原文Making a New Mosquito 
    Bloodsucking mosquitoes are perhaps Earth's most persistent pest, delivering malaria, yellow fever and a host of other diseases each year to more than half a billion people and killing between 2 million and 3 million. Numerous gallons of pesticides are sprayed each year in an effort to wipe out the tiny beasts. But the results have not been good. Many species of mosquitoes have become resistant to insecticides.  

 
 
     For nearly two decades scientists have been thinking of creating a designer mosquito that would have no ability to spread diseases. Finally in 1998, using technologies developed in genetic engineering, scientists succeeded in procing a new type of mosquitoes with red eyes. These mosquitoes not only look different but act in a different way. Every time they suck blood, a substance that recognizes bacteria and kills them will be proced.  
     The major challenge for scientists today is to create a species of mosquitoes that are incapable of transmitting malaria. For this they will have to turn their attention from the laboratory species to malaria-causing species in the wild.  
     As scientists move closer to their goal, they are facing a growing argument over whether it is practicable or wise to create such genetically engineered creatures and set them loose in the environment. One of the problems is that genetically engineered mosquitoes would need to be created for each of the estimated 100 species that carry illnesses that affect humans. Furthermore, strains of these mosquitoes vary from place to place. Even though these problems can be solved, where is the village or town that wants a million or so biting mosquitoes released?

3. She didn't expect that so many people like the books and the book are so successful. 
4. the books are getting darker. 
5. Her favorite writer of all time is Jane Austen 
原文An Interview with a Successful Woman Writer  
(The author of Harry Potter, J. R. Rowling, is being interviewed by a reporter.) 
 
Interviewer: Where do you get your ideas from, Mrs. Rowling? 
Rowling: I wish I knew. Sometimes they just come like magic and other times I have to sit and think for weeks before I manage to work out how something will happen. Where the idea for Harry Potter actually came from I really couldn't tell you. I was traveling on a train between Manchester and London and it just popped into my head. I spent four hours thinking about what Hogwarts would be like -- the most interesting train journey I've ever taken. By the time I got off at King's Cross many of the characters in the books had already been invented.  
Interviewer: Are any of the characters in the books based on real people? Rowling: Tricky question! The answer is yes, and no. I have to confess that Hermione Granger is a little bit like I was at her age, though I was neither as clever nor as annoying. Ron is little bit like my oldest friend and Professor Snape is a lot like one of my old teachers, but I'm not saying which one. 
Interviewer: How long have you been writing? 
Rowling: Nearly all my life. I had written two novels before I had the idea for Harry, though I'd never tried to get them published.  
Interviewer: Did you expect the Harry books to be this successful? 
Rowling: Never. I just wrote the sort of thing I liked reading when I was younger. I didn't expect lots of people to like them, in fact, I never really thought much apart from getting them published.  
Interviewer: Any clues about the next book? 
Rowling: I don't want to give anything away, but I can tell you that the books are getting darker ... Harry's going to have quite a bit to deal with as he 

 
 
gets older. Sorry if they get too scary! 
Interviewer: Who are your favorite authors? 
Rowling: My favorite writer of all time is Jane Austen.

2.      Because everybody else looked so young.  
3.      An old woman was also signing up for a class there to learn something new.

How to Deal with Traumatic Events  
    None of us are fully prepared to deal with traumatic events. We feel devastated whenever property is destroyed or there is a serious injury or a loss of life. We can become overwhelmed when friends, co-workers and loved ones experience tragic, dangerous, life-threatening or violent events. To cope, we can look for support from our community, friends, families, co-workers, employers, or a health care professional. A special meeting within the first 24 to 72 hours of a traumatic incident for the people directly involved as well as others affected is an important step toward recovery.  
     It is critical to discuss what happened, our role, what we thought, as well as our emotional and physical reactions. This may not take place all at once but may need to happen formally and informally over a period of weeks. Without this, the problems associated with traumatic incidents can become chronic and less easy to cure. Talking about traumatic events can become more 

 
 
challenging when an indivial is exposed to repeated traumas over time.

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two可知的形式应是复数，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：“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.
