Questions 26 to 35 are based on the following passage.
Pursuing a career is an essential part of adolescent development. "The adolescent becomes an alt when he26__________ a real job." To cognitive researchers like Piaget, althood meant the beginning of an27__________ .
Piaget argued that once adolescents enter the world of work, their newly acquired ability to form hypotheses allows them to create representations that are too ideal. The28__________ of such ideals, without the tempering of the reality of a job or profession, rapidly leads adolescents to become29__________ of the non-idealistic world and to press for reform in a characteristically adolescent way. Piaget said: "True adaptation to society comes30__________ when the adolescent reformer attempts to put his ideas to work."
Of course, youthful idealism is often courageous, and no one likes to give up dreams. Perhaps, taken31__________ out of context, Piaget's statement seems harsh. What he was32__________ , however, is the way reality can modify idealistic views. Some people refer to such modification as maturity. Piaget argued that attaining and accepting a vocation is one of the best ways to modify idealized views and to mature.
As careers and vocations become less available ring times of33__________ , adolescents may be especially hard hit.

Section B段落匹配
Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.
Can societies be rich and green?
[A] our economies are to flourish, if global poverty is to be eliminated and if the well-being of the world's people enhanced—not just in this generation but in succeeding generations—we must make sure we take care of the natural environment and resources on which our economic activity depends." That statement comes not, as you might imagine, from a stereotypical tree-hugging, save-the-world greenie (环保主义者), but from Gordon Brown, a politician with a reputation for rigour, thoroughness and above all, caution.
[B] A surprising thing for the man who runs one of the world's most powerful economies to say? Perhaps; though in the run-up to the five-year review of the Millennium (千年的)Goals, he is far from alone. The roots of his speech, given in March at the roundtable meeting of environment and energy ministers from the G20 group of nations, stretch back to 1972, and the United Nations Conference on the Human Environment in Stockholm.
[C] "The protection and improvement of the human environment is a major issue which affects the well-being of peoples and economic development throughout the world," read the final declaration from this gathering, the first of a sequence which would lead to the Rio de Janeiro Earth Summit in 1992 and the World Development Summit in Johannesburg three years ago.
[D] Hunt through the reports prepared by UN agencies and development groups—many for conferences such as this year's Millennium Goals review—and you will find that the linkage between environmental protection and economic progress is a common thread.
[E] Managing ecosystems sustainably is more profitable than exploiting them, according to the Millennium Ecosystem Assessment. But finding hard evidence to support the thesis is not so easy. Thoughts turn first to some sort of global statistic, some indicator which would rate the wealth of nations in both economic and environmental terms and show a relationship between the two.
[F] If such an indicator exists, it is well hidden. And on reflection, this is not surprising; the single word "environment" has so many dimensions, and there are so many other factors affecting wealth—such as the oil deposits—that teasing out a simple economy-environment relationship would be almost impossible.
[G] The Millennium Ecosystem Assessment, a vast four-year global study which reported its initial conclusions earlier this year, found reasons to believe that managing ecosystems sustainably— working with nature rather than against it—might be less profitable in the short term, but certainly brings long-term rewards.
[H] And the World Resources Institute (WRI) in its World Resources 2005 report, issued at the end of August, proced several such examples from Africa and Asia; it also demonstrated that environmental degradation affects the poor more than the rich, as poorer people derive a much higher proportion of their income directly from the natural resources around them.
[I] But there are also many examples of growing wealth by trashing the environment, in rich and poor parts of the world alike, whether through unregulated mineral extraction, drastic water use for agriculture, slash-and-burn farming, or fossil-fuel-guzzling (大量消耗) transport. Of course, such growth may not persist in the long term—which is what Mr. Brown and the Stockholm declaration were both attempting to point out. Perhaps the best example of boom growth and bust decline is the Grand Banks fishery. For almost five centuries a very large supply of cod (鳕鱼) provided abundant raw material for an instry which at its peak employed about 40,000 people, sustaining entire communities in Newfoundland. Then, abruptly, the cod population collapsed. There were no longer enough fish in the sea for the stock to maintain itself, let alone an instry. More than a decade later, there was no sign of the ecosystem re-building itself. It had, apparently, been fished out of existence; and the once mighty Newfoundland fleet now gropes about frantically for crab on the sea floor.
[J] There is a view that modem humans are inevitably sowing the seeds of a global Grand Banks-style disaster. The idea is that we are taking more out of what you might call the planet's environmental bank balance than it can sustain; we are living beyond our ecological means. One recent study attempted to calculate the extent of this "ecological overshoot of the human economy", and found that we are using 1.2 Earth's-worth of environmental goods and services—the implication being that at some point the debt will be called in, and all those services—the things which the planet does for us for free-will grind to a halt.
[K] Whether this is right, and if so where and when the ecological axe will fall, is hard to determine with any precision—which is why governments and financial institutions are only beginning to bring such risks into their economic calculations. It is also the reason why development agencies are not
united in their view of environmental issues; while some, like the WRI, maintain that environmental progress needs to go hand-in-hand with economic development, others argue that the priority is to build a thriving economy, and then use the wealth created to tackle environmental degradation.
[L] This view assumes that rich societies will invest in environmental care. But is this right? Do things get better or worse as we get richer? Here the Stockholm declaration is ambiguous. "In the developing countries," it says, "most of the environmental problems are caused by under-development." So it is saying that economic development should make for a cleaner world? Not necessarily; "In the instrialized countries, environmental problems are generally related to instrialisation and technological development," it continues. In other words, poor and rich both over-exploit the natural world, but for different reasons. It's simply not true that economic growth will surely make our world cleaner.
[M] Clearly, richer societies are able to provide environmental improvements which lie well beyond the reach of poorer communities. Citizens of wealthy nations demand national parks, clean rivers, clean air and poison-free food They also, however, use far more natural resources—fuel, water (all those baths and golf courses) and building materials.
[N] A case can be made that rich nations export environmental problems, the most graphic example being climate change. As a country's wealth grows, so do its greenhouse gas emissions. The figures available will not be completely accurate. Measuring emissions is not a precise science, particularly when it comes to issues surrounding land use; not all nations have released up-to-date data, and in any case, emissions from some sectors such as aviation are not included in national statistics. But the data is exact enough for a clear trend to be easily discernible. As countries become richer, they proce more greenhouse gases; and the impact of those gases will fall primarily in poor parts of the world.
[O] Wealth is not, of course, the only factor involved. The average Norwegian is better off than the average US citizen, but contributes about half as much to climate change. But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels? That question, repeated across a dozen environmental issues and across our diverse planet, is what will ultimately determine whether the human race is living beyond its ecological means as it pursues economic revival.

Section C仔细阅读
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A. , B. , C. and D.. You should decide on the best choice and mark the corresponding letter on Answer sheet with a single line through the centre.
Passage One
Questions 46 to 50 are based on the following passage.
Interactive television advertising, which allows viewers to use their remote controls to click on advertisements, has been pushed for years. Nearly a decade ago it was predicted that viewers of "Friends", a popular situation comedy, would soon be able to purchase a sweater like Jennifer Aniston's with a few taps on their remote control. "It's been the year of interactive television advertising for the last ten or twelve years," says Colin Dixon of a digital-media consultancy.
So the news that Cablevision, an American cable company, was rolling out interactive advertisements to all its customers on October 6th was greeted with some skepticism. During commercials, an overlay will appear at the bottom of the screen, prompting viewers to press a button to request a free sample or order a catalogue. Cablevision hopes to allow customers to buy things with their remote controls early next year.
Television advertising could do with a boost. Spending fell by 10% in the first half of the year. The popularization of digital video recorders has caused advertisers to worry that their commercials will be skipped. Some are turning to the Internet, which is cheaper and offers concrete measurements like click-through rates—especially important at a time when marketing budgets are tight. With the launch of interactive advertising, "many of the dollars that went to the Internet will come back to the TV," says David Kline of Cablevision. Or so the instry hopes.
In theory, interactive advertising can engage viewers in a way that 30-second spots do not Unilever recently ran an interactive campaign for its Axe deodorant (除臭剂), which kept viewers engaged for more than three minutes on average.
The amount spent on interactive advertising on television is still small. Magna, an advertising agency, reckons it will be worth about $138 million this year. That falls far short of the billions of dollars people once expected it to generate. But DirecTV, Comcast and Time Warner Cable have all invested in it. A new effort led by Canoe Ventures, a coalition of leading cable providers, aims to make interactive advertising available across America later this year. BrightLine iTV, which designs and sells interactive ads, says interest has surged: it expects its revenues almost to triple this year. BSkyB, Britain's biggest satellite-television service, already provides 9 million customers with interactive ads.
Yet there are doubts whether people watching television, a "lean back" medium, crave interaction. Click-through rates have been high so far (around 3-4%, compared with less than 0.3% online), but that may be a result of the novelty. Interactive ads and viewers might not go well together.
46. What does Colin Dixon mean by saying "It's been the year of interactive television advertising for the last ten or twelve years(Lines 4-5, Para. 1)?
A. Interactive television advertising will become popular in 10-12 years.
B. Interactive television advertising has been under debate for the last decade or so.
C. Interactive television advertising is successful when incorporated into situation comedies.
D. Interactive television advertising has not achieved the anticipated results.
47. What is the public's response to Cablevision's planned interactive TV advertising program?
A. Pretty positive.
B. Totally indifferent.
C. Somewhat doubtful.
D. Rather critical.
48. What is the impact of the wide use of digital video recorders on TV advertising?
A. It has made TV advertising easily accessible to viewers.
B. It helps advertisers to measure the click-through rates.
C. It has placed TV advertising at a great disadvantage.
D. It enables viewers to check the sales items with ease.
49. What do we learn about Unilever's interactive campaign?
A. It proves the advantage of TV advertising.
B. It has done well in engaging the viewers.
C. It helps attract investments in the company.
D. It has boosted the TV advertising instry.

第一篇：
Merchant and passenger ships are generally required to have a life preserver for every person aboard and in many cases, a certain percentage of smaller sizes for children. According to United States requirements, life preservers must design, reversible capable of being quickly adjusted to fit the uninitiated indivial, and must be so designed as to support the wearer in the water in an upright or slightly backward position.
Sufficient buoyancy(浮力) to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage. Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire.?The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious.
The method of adjustment to the body should be simple, and self-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster. Thus, the life be reversible that it is nearly impossible to get it on wrong. Catches, straps, and ties should be kept to a minimum. In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities. A suitable life also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim.
1. The passage is mainly about____.
A) the uses of life preservers
B) the design of life preservers
C) the materials for life preservers
D) the buoyancy of life preservers
2. According to the passage, a life be first of all ____.
A) adjustable B) comfortable C) self-evident D) self-righting
3. United States Coast Guard does NOT require the life preserver to be made ____.
A) with as few strings as possible
B) capable of being worn on both sides
C) according to each wearer's size
D) comfortable and light to wear
4. By “the uninitiated indivial” (Para. 1, Line. 4) the author refers to the person ____.
A) who has not been instructed how to use a life preserver
B) who has a little experience in using a life preserver
C) who uses a life preserver without permission
D) who becomes nervous before a disaster
5. What would happen if a person were supported by the life preserver in a wrong position?
A) The waves would move him backwards.
B) The water would choke him.
C) He would immediately sink to the bottom.
D) He would be exhausted or unconscious.
第二篇：
The table before which we sit may be, as the scientist maintains, composed of dancing atoms, but it does not reveal itself to us as anything of the kind, and it is not with dancing atoms but a solid and motionless object that we live. So remote is this “real” table——and most of the other “realities” with which science deals——that it cannot be discussed in terms which have any human value, and though it may receive our purely intellectual credence it cannot be woven into the pattern of life as it is led, in contradistinction to life as we attempt it. Vibrations in the ether(以太) are so totally unlike the color, purple that the gulf between them cannot be bridged, and they are, to all intents and purposes，not one but two separate things of which the second and less “real” must be the most significant for us. And just as the sensation which has led us to attribute all objective reality to a non-existent thing which we called “purple”is more important for human life than the conception of vibrations of a certain frequency; so too the belief in God; however ill founded, has been more important in the life of man than the germ theory of true the latter may be.
We may, if we like, speak of consequence, as certain mystics love to do, of the different levels or orders of truth. We may adopt what is essentially a Platonistic (布拉图式的) trick of thought and insist upon postulating the existence of external realities which correspond to the needs and modes of human feeling and which, so we may insist, have their being in some part of the universe unreachable by science. But to do so is to make an unwarrantable assumption and to be guilty of the metaphysical fallacy of failing to distinguish between a truth of feeling and that other sort of truth which is described as “truth of correspondence” and it is better perhaps, at least for those of us who have grown up in thought, to steer clear of such confusions and to rest content with the admission that, though the universe with which science deals is the real universe, yet we do not and cannot have any but fleeting and imperfect contacts with it; that the most important part of our lives-our sensations, emotions, desires and aspirations-take place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.
1. The author suggests that in order to bridge the puzzling difference between scientific truth and the world of illusion, the reader should____.
A) try to rid himself of his world of illusion
B) accept his words as being one of illusion
C) apply the scientific method
D) learn to acknowledge both
2. Judging from the ideas and tone of the selection, one may reasonably guess that the author is ____.
A) a humanist B) a pantheist C) a nuclear physicist D) a doctor of medicine
3. According to this passage, a scientist would conceive of a “table” as being ____.
A) a solid motionless object
B) certain characteristic vibrations in “ether”
C) a form fixed in space and time
D) a mass of atoms in motion
4. The topic of this selection is____.
A) the distortion of reality by science
B) the confusion caused by emotions
C) Platonic and contemporary views of truth
D) the place of scientific truth in our lives
5. By “objective reality” (Last line, Para. 1) the author means____.
A) scientific reality
B) a symbolic existence
C) the viewer's experience
D) reality colored by emotion

第一篇：
1. B
文章主要讲述了救生衣的设计。间接题型段首主旨题。C项和D项都是对救生衣设计中设计材料的说明。A项为陷阱，指救生衣的用途，尽管开头提到，但范围不着边际。故只有B是正确选项。
2. D
根据文章，救生衣首先会自动扶正。事实细节题。本文第三段主要讨论救生衣落水位置，应设计的能“自动扶正”,或稍向后仰。B项是对材料的描述，范围太窄，而A和C不合题意，因此D是正确答案。
3. C
美国海岸巡逻队不需要救生衣根据穿戴者的尺寸生产。事实细节题。A项和B项都涉及method，其相关部分见最后一段第三句，A，B，D三项都是文章中提及的，C项与本题无关的'内容，因此应该选C。
4. A
“the uninitiated indivial”作者指的是不知道怎么使用救生衣的人。语义指代题。根据文章最后一段第一句，我们可推出“the uninitiated indivial”就是指的那些不知道怎么使用救生衣的人。故A是正确选项。
5. D
如果一个人没有正确使用救生衣，就会发生什么?细节辨别题。第三段第一句后半句中a face-down position和本题中的 in a wrong position相对应。因此选项D“他可能太累了或者是已经失去知觉”是正确答案。
第二篇：
1. B
作者暗示为了联系起科学世界和虚幻世界的不同点，把他的话当作一种假相。间接题型段尾结论题。根据第二段最后一句话，我们可推出B是正确答案。
2. A
由文章的观点及语气可推知作者是人文主义者。暗示推断题。文中第一段第一句后半句提到“...but a solid and motionless object that we live”由此我们可以推出该作者是一位人文主义者。
3. D
根据文章，科学家相信“table”就是一群运动的原子。直接题型语义指代题。根据第一段第一 句的前半句“...but it does not reveal itself to us as anything of the kind, and it is not with dancing atoms ...”我们可推出D是正确答案。
4. D
文章的主题为生活中科学真理的地位。段首主旨题。从第二段最后一句后半句“...that the most important part of our lives-our sensations, emotions, desires and aspirations-takes place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.”我们可以推断出本文只要讲了科学真理在现实生活中的地位。因而答案应选D。
5. A
对于作者，“objective reality”意味着科学现实。语义指代题。根据文章最后一段，我们可得知“objective reality”即科学现实的意思，因而，答案应该选A。

Directions: For this part, you are allowed 30 minutes to write an essay on the use of translation apps. You can start your essay with the sentence "The use of translation apps is becoming increasingly popular. " You should write at least 120 words but no more than 180 words.
【参考范文】
The use of translation apps is becoming increasingly popular. Consequently ,people are getting more opportunities to speak or meet another language but their own mother tongue with the development of the economy. Undoubtedly , an app of translation is crucial for people who cannot handle the language perfectly. But the viewpoints are split one whether this kind of apps are wholly a good thing.
Where there is a light , there is a shadow. Some people argue that a translation app will bridge them with the native speakers adequately no matter who will be a traveler or a businessman. It will pose a huge threat for people who can not understand what they say. Fortunately , everyone will interact richly with the apps like this. On the other hand, some people think that the translations app cannot fully create and convey the feelings on the authentic language. As a result , it will bring more misunderstandings. Besides, the opponents take the point of view that people will be more over-reliant on the mobile-phones and Internet.
Form where I stand , I would take the the translation on this kind of apps as a reference rather than a kind of dependence. The most effective and beneficial way to express yourself and communicate with a foreigner is to improve one’s ability to exert this unfamiliar language. As an old saying goes is Practice makes perfect.
【参考译文】
在经济飞速发展的当下，人们有越来越多的机会使用外语。所以对那些外语说的没有那么好的人来说，一款翻译软件就至关重要。可是人们对这款软件却有不同的看法。
凡事皆有两面，有些人觉得这样的软件可以很好地沟通人们，不管你是旅行或者和一个外国人谈生意。如果语言不通会造成很大困扰，但有了这样的软件，大家的交流会更顺畅从而提高效率。但是另一方面，有些人会觉得这种软件有时候不能准确地表情达意从而造成误会，再者，这会使人过分依赖手机和网络。
于我而言， 我觉得更好的是把这些软件里的翻译当做一种参考，而不应过度相信和使用。最有效和有用的提高个人表达自己和与外国人沟通能力的方式就是学会去掌握这门陌生语言。所谓熟能生巧。

2019年大学英语四级考试阅读模拟试题：女人的地位
It is not often realized that women held a high place in southern European societies in the 10th and 11th centuries. As a wife, the woman was protected by the setting up of a dowry (彩礼). Admittedly, the purposeof this was to protect her against the risk of desertion, but in reality its function in the social and family life of the time was much more important. The dowry was the wife’s right to receive a tenth of all her husband’扰卜s property. The wife had the right to with hold consent, in all transactions the husband wouldmake, and more than just a right; the documents show that she enjoyed a real power of decision, equal to that of her husband. In no case do the documents indicate any degree of difference in the legal status of husband and wife.
The wife shared in the management of her husband’s personal property, but the opposite was not always true. Women seemed perfectly prepared to defend their own inheritance against husbands who tried to exceed their rights, and on occasion they showed a fine fighting spirit. A case in point is that of Maria Vivas. Having agreed with her husband Miro to sell a field she had inherited, for the needs of the household, she insisted on compensation. None being offered, she succeeded in dragging her husband to the scribe(法学家) to have a contract ly drawn up assigning her a piece of land from Miro’s personal inheritance. The unfortunate husband was obliged to agree, as the contract says, “for the sake of peace.” Either through the dowry or through being hot-tempered, the wife knew how to win herself, with the context of the family, a powerful economic position.ric illnesses including depression often do not manifest themselves until the late teens or early 20s.
练习题：
Choose correct answers to the question:
1. A decimum was ________.
A. the wife's inheritance from her father
B. a gift of money to the new husband
C.a protection of the wife’s right
D. a written contract
2. In the 10th and11th centuries in southern European, women’s social position was ______.
A. higher than men’s
B. as high as men’s
C. lower than men’s
D.never recognized
3.The purpose of mentioning the case of Maria Vivas_____
A.to show women had the same rights as,if not more than,their husband
B.to prove hot-tempered woman held a powerful economic position
C.to tell the readers the real situations in some countries
D.to show the fight spirits of woman
4.Could a husband sell his wife's inheritance?
A. Yes, if she agreed.
B. No, under no circumstances.
C. Yes, whenever he wished to.
D, Yes, if his father-in-law agreed.
5. Which of the following is NOT mentioned as an effect of the dowry system?
A. The husband had to share the power of decision in marriage.
B. The wife could manage her husband’s personal property.
C. The wife gained a powerful economic position.
D. The wife would not be deserted by her husband.
参考答案及解析
1.[C] 词义推断题。第1段第2句指出了 decimum的作用，即与“彩礼”相当，作为保护妇女的工具。第4句以 “The decimum was...”的句式指出其定义，综合这两句，可断定选项C正确。
2.[B] 推理判断题。文章第1句就表明妇女当时的地位很高，第1段最后两句表明妇女与其丈夫的地位并无不同，是平等的，因此可以推断本题答案应为B。
3.[A] 推理判断题。本题考查例子与观点的关系。该例子是为了证明其前面，即第2段开头两句的观点,选项A是对这两句话的总结。
4.[A]推理判断题。本题考査从例子的推断。根据Maria Vivas的例子可确定答案，而且从第2段第4句中的Having agreed with her husband可推断售卖妻子继承的财产必须先征得妻子的同意，因此选项A正确。
5.[D] 事实细节题。可用排除法找出答案。第1段倒数第2句可证明选项A正确，第2段首句可证明选项B正确，第2段末句可表明选项C正确，只有选项D太绝对。
2019年大学英语四级考试阅读模拟试题：单词拼写
There is a popular belief among parents that schools are no longer interested in spelling .No school I have taught in has ever _____ spelling or considered it unimportant as a basic skill. There are, however , vastly different ideas about how to teach it , or how much _____ it must be given over general language development and writing ability. The problem is , how to encourage a child to express himself freely and _____ in writing with out holding him back with the complexities of spelling? If spelling become the only focal point of his teacher’s interest, clearly a __4__ child will be likely to “play safe”. He will tend to write only words within his spelling range, choosing to avoid __5__ language. That’s why teachers often __6__ the early use of dictionaries and pay attention to content rather than technical ability. I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience ：“ This work is __7__ !There are far too many spelling errors and your writing is illegible( 难以辨认的 ).” It may have been a sharp __8__ of the pupil’s technical abilities in writing, but it was also a sad reflection on the teacher who had omitted to read the essay, which __9__ some beautiful expressions of the child’s deep feelings.
The teacher was not wrong to draw attention to the errors, but if his priorities had centred on the child’s ideas, an expression of his disappointment with the presentation would have given the pupil more __10__ to seek improvement.
A)priority B)criticism C)contained D)clearly
E)adventurous F ) discourage G)motivation H)terrible
I)ignored J)difficult K)encourage L)expressed
M)confidently N)bright O)motive L)expressed
答案及解析:
1. 选 I )。 由该句中的 has 可知，此处应填动词过去式，且表达的含义应和后面的 consider…unimportant 相近，故应排除 contained 和 expressed
而选择 ignored 。
2. 选 A )。 此处应填名词，但能与后面 over 构成固定搭配的名词只有 priority ，故排除 了 criticism 和 motivation 。
3. 选 M). 由空格前面的 and 可知，此处应填副词和 freely 并列。从句意来理解，在没有拼写困难的情况下，怎样鼓励学生自由且 …… 地表达自己，选项中只有 confidently “自信地“符合题意。
4. 选 N )。 很明显这里应填形容词，选项中 terrible ， difficult 后接事物名词 something ，只有 adventurous 和 bright 可用来形容 somebody ( child )，再由后面的play safe“不冒险”，可排除adventurous而选择bright。
5. 选 E )。 由前一句中的 be likely to “ play safe ”和空格前的 avoid 可以推知，此处所填词的意思应与play safe表达的意思相反，故选项中只有adventurous符合题意。
6. 选 K )。 很明显此处应填动词的一般现在时，可选项有 encourage 和 persuade 。由 That’s why 知本句与前一句构成因果关系，而前一句说的是学生往往会用他们拼写范围内的词写文章，从而选择避免用那些不会的词，故由此可推知此句应理解为老师鼓励学生用字典，因此排除 persuade 而选 encourage。
7. 选 H )。 此处应填形容词。由空格后面的 too many spelling errors 和illegible可知，这篇文章是写的很糟，而不是很难理解。故排除difficult而选terrible。
8. 选 B )。 此处应填名词。由后半句中 a sad reflection on the teacher 可知，前半句是在指责学生，故选项中只有criticism符合题意。
9. 选 C )。 此处填动词过去式，本句中由 which 引导的从句是对 essay 的解释，剩余选项中 contained 和 expressed ，根据句意，文章 …… 儿童内心感受的一些好的表达，故只有contained 符合题意。
10. 选 G )。 此处应填名词。根据句意，如果老师更注重学生思想的表达的话，会给学生更大的动力去寻求提高;故排除 motive “动机，原因”而选 motivation 。
全文翻译：
家长们普遍认为中学现在已不再关注单词的正确拼写了。但我所教过的学校从来没有忽视过拼写，或就一种基本技能来说从没有认为它不重要。然而对于怎么来教拼写或者是从提高整个语言的发展和写作能力方面来说，把拼写放在什么样优先的地位存在着许多不同的看法。所存在的问题是，在写作当中怎样鼓励孩子不要让复杂的拼写来影响他流畅地，自信地表达自己的思想。
如果字的拼写成为老师关心的惟一焦点，很明显，聪明的孩子很可能就会为“保险起见”，只写一些他会写的字，避免因冒险而出错的语言。那就是为什么老师常常鼓励学生很早就要使用字典，而且写作时重视内容而非拼写技能。
有一次我非常震惊，在一篇描写个人经历的感情细腻的文章后面读到了这些话：“这篇糟透了!单词拼写错误太多。自己很难辨认!”这对于一个学生的写作技能也许是一次尖锐的批评，但它同时也悲哀地反映出那位老师忽视了去阅读一篇包含了表达孩子内心感情的文章。老师注意到了这些问题并没有错，但是如果他把重点放在关注孩子的思想上，只表示出他对孩子的拼写错误有点失望，就会给学生更大的动力去进一步提高。
