　　Ⅱ.閱讀理解

　　A

　　What would you think if I told you I could eat 40 percent more food than other people—eating boxes of ice cream, bowls of noodles and plates of meat—all while losing weight?

　　You might hate me, thinking I have one of those annoyingly good metabolisms(新陳代謝)that just burn up fat the instant it enters my body.You might wonder if I have an intestinal(腸的)worm, or perhaps an eating disorder.Or maybe you'd just shrug your shoulders and figure I have a rich fantasy life.

　　You'd be wrong.

　　For my body to finish such a surprising task, I would have to be a mouse.Not just any mouse, but one lucky enough to be involved in a new study at Baylor College of Medicine in Houston.

　　After identifying an enzyme(酶)that allows fat to be stored in the body, scientists fed mice without those enzymes, and found those mice were able to consume far more food than other mice—and still weigh 10 to 15 percent less.

　　Best of all, the mice that had no enzymes were in very good health, producing baby mice with no problem and generally acting like any other mouse.That's great news for obesity researchers, who think that scientists may figure out a way to prevent the fatmetabolizing(脂肪代謝)enzyme in humans and control weight gain.And such a pill would be very exciting for many people who are struggling to get rid of dangerous extra pounds.

　　But don't start planning any big dinner just yet. At this point, of course, any pill for humans is but a twinkle(閃爍) in the eye of every medicine company's CEO.More tests are to be made, and eventually humans will be introduced in the test.

　　But for now，unfortunately，control in diet is still the key.

　　11．What does “such a surprising task” in Paragraph 4 refer to?

　　A．Eating a lot of food while losing weight.

　　B．Burning up fat very quickly.

　　C．Controlling the diet.

　　D．Having a rich fantasy life.

　　12．Why did the author say he/she had to be a mouse in Paragraph 4?

　　A．Because a mouse can lose weight no matter how much it eats.

　　B．Because the weight losing tests were made on the mouse.

　　C．Because the mouse has a very good metabolism.

　　D．Because the author wants to try the food without the enzyme.

　　13．In the experiment, the mice without those enzymes

　　________.

　　A．were in good condition

　　B．put on weight

　　C．became weak

　　D．could not have baby mice

　　14．What does the author want to show through the last two paragraphs?

　　A．You can be free of guilt when having big dinners.

　　B．Scientists cannot find the key to identifying the

　　enzyme.

　　C．Don't overeat before the test is made on humans.

　　D．It is unnecessary to control weight at present.

　　B

　　These fast food restaurants constantly remind us of the American fondness with hamburgers，chips and pizza.But America's reputation as the home of fast food is under threat from the British，according to a research carried out by the BBC in 13 nations among 9,000 people.

　　Despite fears over obesity，the study found the British are more obsessed with junk food than any other nation.

　　Almost half of British respondents(參與調查者)said they enjoyed fast food too much to give it up. About 44 percent in the US claimed they would be unable to stop eating burgers，pizzas and chicken wings，making the country second in the world's junk food league. The third place went to the United Arab Emirates，where 35 percent are junk-food lovers.

　　The research also found that attitudes to food and weight vary wildly around the world. Those in the UK and US believed lack of self-discipline was the main factor behind growing waistlines(腰圍). They can't deny themselves that hamburger or extra piece of pizza，but “make themselves feel better by washing it down with a diet coke”，the study suggested.

　　The French，on the other hand，seem to keep a watchful eye on their weight. They get on the scales every day. Only 19 percent of the French surveyed admitted a fondness for fast food.

　　Thierry Pailleux，of France，from the market research firm that conducted the poll，said the French valued the combination of good food and company. Sharing classic food and time with loved ones is key to the French sensibility. “French people take care of their image as a matter of course. Being thin is part of our culture and a point of pride. We are known for it，” said Pailleux.“On top of this，there is increasing awareness of the devastation(傷害)that obesity can cause to one's health.”

　　15．What's the main idea of the passage?

　　A．A study of different attitudes towards fast food.

　　B．How popular fast food is in foreign countries.

　　C．Different countries' attitudes towards food and body weight.

　　D．A study of how popular fast food is in foreign countries.

　　16．The research shows that ________.

　　A．Americans are proud of the fast foods they eat

　　B．those British who love fast foods do not care about their body weight

　　C．the British would like to think that other foods they eat make up for eating occasional fast food

　　D．most Americans believe the enjoyment of food is more important than its possible effect on their waistlines

　　17．What's the meaning of the underlined word “obsessed” in the second paragraph?

　　A．Crazy.

　　B．Obese.

　　C．Opposed.

　　D．Neutral.

　　18．Why are，according to Thierry Pailleux，the French less obsessed with fast food than the British and Americans？Because ________.

　　A．they value their image

　　B．they have better foods than other countries

　　C．they value self-discipline

　　D．they are afraid of having an unhealthy diet

　　6．C　考查動詞短語辨析。句意： 得知老板同意我可以通過做一些事情來一筆勾銷我的債務，我很高興。write off the debt是指“一筆勾銷債務”。

　　想品嘗美味又害怕體重增加？休斯敦貝勒醫學院的一項實驗將會幫你消除這個顧慮。

　　11．A　信息指代題。此處所說的任務是指第一段中作者指出的大量進食體重還不增加，故選A。

　　12．B　細節理解題。作者在第四段指出要想多吃還不胖，除非變成休斯敦貝勒醫學院減肥實驗中所用的那只老鼠，故選B。

　　13．A　細節判斷題。根據第六段第一句話可知，沒有酶的老鼠的身體仍然健康如故，能繁育后代，行為與其他老鼠并無兩樣，故選A。

　　14．C　推理判斷題。文章最后兩段說明此類藥物仍在開發過程中，還未在人類身上進行實驗，目前要想保持體重，關鍵還是在于不要過量飲食，故選C。

　　B

　　全文都在談論由BBC進行的調查，內容是各國迷戀快餐的人口比例及背后的原因，最后還說了不太喜歡快餐的法國人并分析了原因。

　　15．D　主旨大意題。全文都在談論“a research carried out by the BBC”，內容是各國迷戀快餐的人口比例還有背后的原因，最后還說了不太喜歡快餐的法國人并分析了原因，所以D項正確。

　　16．C　細節理解題。文章開始說了美國式快餐的發源地，但并沒表明他們對吃快餐很自豪，所以A項錯誤。根據第二段可排除B項。根據第四段“They can't deny themselves that hamburger or extra piece of pizza，but ‘make themselves feel better by washing it down with a diet coke’，the study suggested.”看出C項是正確的。原文只是說美國人覺得(忍不住要吃快餐)缺乏自律才導致肥胖，但并不是覺得從吃快餐得到的快樂比對體重的影響更重要。所以D項錯誤。

　　17．A　詞義猜測題。從本段的前半部分猜出詞義。

　　18．A　細節理解題。由最后一段的“French people take care of their image as a matter of course.”看出答案。

　　.19.It will be three months before　It is/will be＋一段時間＋before…表示“多久以后才能……”，此處用將來時。

　　20．have been in heavy debt　be in heavy debt負債累累。因為有since短語，此處用現在完成時。

　　21．Picking up some junk　此處動名詞作主語。

　　22．ought to have arrived　should/ought to have done“本應該做的事情沒有做”，含責備、責難之意。

　　23．(which were) considered impossible in the past　considered sth impossible“認為……不可能”，此處可用定語從句或者過去分詞作定語。

　　24．must have been scolded　對過去的肯定推測用must have done句式。

　　25．shouldn't have left home

　　26．can our army avoid being spied on　by no means在從句句首，所以用倒裝句。“avoid＋v.-ing”是固定結構，所以用avoid being spied on。

　　27．got tired of living in the city　get/be tired of對……膩了，厭倦了，煩了。

　　28．getting away with　“imagine＋v.-ing”是固定結構；get away with僥幸成功，僥幸逃脫。
