② 新视野大学英语第四册 unit7A The coming energy crisis

Two hundred years ago, the world experienced an energy revolution that launched the Instrial Age. Ever since then, with the rapid increase of population density, the instrialized world's thirst for energy has more than tripled. Petroleum and natural gas are exploited as versatile and high quality energy procts. Uranium is also tapped to fuel nuclear reactors and provide atomic energy.

两百年前，全球经历了一场能源革命，由此引发了工业时代的到来。从那时起，随着人口密度的迅速增加，工业国家对于能源的需求成倍成倍增加。石油和天然气被看作是用途多、质量好的能源产品而得到开发，而铀也得以开发，为核反应堆提供燃料并供应原子能源。

Cheap energy is the lifeblood of human society. But there is a dark side to the near monopoly of non-renewable fossil fuels like coal, oil and natural gas， along with controversial uranium, to supply our growing energy demands.

廉价能源是人类社会的命脉。但是，几乎垄断煤炭、石油和天然气等不可再生化石燃料，以及有争议的铀，以满足我们日益增长的能源需求，还有一个阴暗面。

The supply of these fuels is physically limited, and their use threatens our health and environment. Multiple international treaties have been proposed to limit the use of fossil fuels for this very reason.

这些燃料的供应实际上是有限的，它们的使用威胁到我们的健康和环境。为此，已经提出了多项国际条约来限制化石燃料的使用。

Fears of global warming aside， burning fossil fuels releases chemicals and particulates that can cause breathing problems, cancer as well as brain and nerve damage. Nuclear energy, once hailed as"too cheap to meter"， has never been economically successful when all costs are factored in.

抛开对全球变暖的担忧不谈，燃烧化石燃料会释放出化学物质和微粒，导致呼吸问题、癌症以及大脑和神经损伤。核能曾被誉为“太便宜，无法计量”，但如果将所有成本都考虑在内，它在经济上从未取得成功。

Furthermore, public opinion polls show nuclear energy is too closely associated with disasters like the Chernobyl reactor meltdown and the Fukushima explosion, and with the danger that: rebel insurgents could do damage with the toxic waste.

此外，民意调查显示，核能与切尔诺贝利（Chernobyl）反应堆熔毁和福岛（Fukushima）爆炸等灾难有着太密切的联系，而且还存在着这样的危险：反叛分子可能用有毒废料造成破坏。

Inexpensive and seemingly abundant non-renewable energy from dead plants and extinct animals fueled the 20th century economy, but geologists, climatologists,environmentalists, and many others are warning that the honeymoon may soon be over.

从死去的植物和灭绝的动物身上获得的廉价且看似丰富的不可再生能源推动了20世纪的经济发展，但地质学家、气候学家、环境学家和许多其他人警告说，蜜月可能很快就结束了。

Sticking to high moral standards is easier said than done. Once, a young British car sales manager
who had just finished courses on business ethics was sent to sell cars to an African country. The
negotiations had been going on for months without any real results．He was at his wits' end. Finallyxhe
hit upon a solution．One day he bought a popular novel and slipped a check of #20,000 in the book.
Then he presented it to the minister in charge of transportation. This minister examined its contents，
pretending he didn’t see the check at all．Then he said with a smile："Young man，I hear London is at
its best in May.”The sales manager, who was quick-witted, replied: "My company in London will be
most honored to welcome your visit！”A short time later, the deal was approved in London！

⑥ 新视野大学英语4第六、七单元的选词填空答案详解

Ⅰ. 1. sports 2. Let‟s 3. basketballs 4. sounds 5. collection6. has 7. watches 8. difficult 9. interesting 10. boring Ⅱ. 1. A 题意：你有两只乒乓球拍吗？由可知bat的形式应是复数，故选A。 2. B 题意：“这些是什么？”“它们是足球。”由these可知答语中主语的形式应是复数，应用they来指代，所以答案为B。 3. D 题意：她每天做运动。当主语是第三人称单数时，动词要用第三人称单数形式，play的第三人称单数是plays，否定形式应是doesn‟t play。故选D。 4. B 题意：你看电视吗？ look at强调动作，see强调看的内容，“看电视”和“看球赛”一般用watch，由于do引导的一般疑问句后跟动词原形，所以不用watches，故选B。 5. A 题意：“我们看电视吧。”“不，听起来很无聊。我们打篮球吧。” boring意为“无聊的”，interesting和fun意为“有趣的”，difficult“困难的”，根据题意应选A项。 6. C 题意：“我们踢足球吧！”“听起来好极了。”球类前不加冠词，故选C。 7. D 题意：“你的弟弟有钢笔吗？”“是的，他有。”does引导的一般疑问句的肯定答语应是Yes, hedoes.故选D。 8. A 题意：我喜欢在电视上看足球比赛。“在电视上”应用介词on。 9. C 题意：他不打棒球。由于he是第三人称单数，所以助动词为does，否定形式为doesn‟t，does后跟动词原形，be动词后不能跟动词原形，故选C。 10. A 题意：我妈妈喜欢排球，她认为排球令人轻松。relaxing “令人轻松的”，boring“无聊的”，difficult“困难的”，not good“不好的”，根据题意应选A。 11. D 题意：“我们打网球吧！”“听起来不错。”根据题意应是“听起来”而不是“看起来”；又由于that是单数所以动词要用第三人称单数形式，故选D。 12. B 题意：我爸爸有十只网球拍。he为第三人称单数, have的第三人称单数是has，故选B。 13. A 题意：我们喜欢足球。我们有五个足球。根据题意是 “喜欢足球”，we是复数，所以like用原形，故选A。 14. D 题意：“你们有电视机吗？”“是的，我们有。”本句是do引导的一般疑问句，由于do是助动词，所以肯定答语应是Yes, we do.故选D。 15. C 题意：我们玩电脑游戏吧！ let后跟不带to的不定式，结构为let sb. do sth.，故选C。Ⅲ. 1. has 2. don‟t 3. them 4. sounds 5.doesn‟t Ⅳ. 1. What does；have 2. Does；have；No；doesn‟t 3. don‟t play 4. They have；rackets 5. Does he like Ⅴ. 1. plays sports 2. Do；have 3. Let‟s play 4. sounds interesting 5. watch; on Ⅵ. 1. A 根据句意是做自我介绍，所以应是“我的”名字。 2. C 句意是“我有两个朋友”，I是第一人称，所以用动词原形have。 3. C 从下文人名可确定是sisters，如果是朋友，friend应用复数形式。 4. A their是形容词性物主代词“他们的”，B项和C项是单数形式，D项“我们的”不符合句
意。 5. B all指三者或三者以上，A、C、D三项都是单数形式。 6. B I是第一人称，所以用动词原形like。A项不合逻辑。 7. D 由too“也”可知两人的爱好是一样的，都是soccer ball。 8. C 句意是“她有三个篮球”，she是第三人称单数,所以应是has 。 9. B 句意是“我们放学后打篮球”，we是复数，后用动词原形。be动词后不跟动词原形，所以C项不正确。 10. A 表示“在电视上”应用介词on。Ⅶ. 1. A 根据文中第三句话“I have a sister，but I don‟t have a brother.”可知答案为A。 2. D 根据文中“I likesports.”“I collect 4 tennis rackets.”和“I likeping-pong, too.”可知答案为D。 3. C 根据文中“I playping-pong with my friends.”可知答案为C。 4. B 根据短文内容可知Becky是11岁； Becky没有兄弟； Becky也喜欢乒乓球。只有B项和原文相符。 5.
