Smokers who quit tend to pack on an average of 5 pounds after they stop smoking cigarettes. A new study, published by the journal Science, explains why this happens.The new research explains that nicotine appears to combine with appetite-regulating neurons (调节食欲的神经元) in the brain, besides the receptors (感受器) that bring about addiction. These neurons help regulate how much food gets consumed, but under the influence of nicotine, they lose their selfcontrol. This is why when smokers quit, they tend to eat more and gain weight.The researchers believe that their discovery will lead to the development of drugs that aim at nicotine receptors on brain cells that control appetite. In the future, weight gain may no longer be a reason for smokers to delay the decision to kick the habit, but thats no reason to wait. Nicotine-replacement treatment, while not for everyone, can help. Here are a few more ways to quit smoking and stay slim.Drink water. To improve metabolic (新陈代谢的) rates which is helpful in losing weight, make half of those glasses ice water. Juice can be too high in calories, something youll want to keep an eye on your journey toward being a slimmer nonsmoker.Plan your snacks. Healthy snacks help keep your metabolism working, so you continue to burn calories while stopping wild hunger pain, or fake hunger.Keep moving. Exercise kills two birds with one stone. It helps you burn calories and prevents you from eating when youre not truly hungry. Its also a feelgood stress reliever (缓解物)Focus on your fitness and how being healthy makes you feel. Make exercise a goal and think of quitting as your reward for being physically fit.1Which of the following changes peoples appetite according to the new research?ANicotine.BAppetiteregulating neurons.CThe receptors that bring about addiction.DThe food that has been consumed.2By saying “but thats no reason to wait” in Paragraph 3, the author means that _.Asome new drugs are going to be developed soonBnicotinereplacement treatment cannot help everyoneClosing weight shouldnt be an excuse for smokingDsome ways to quit smoking while staying slim are available3The author believes that _.Aice water can improve metabolic ratesBsmokers should eat fewer snacks to keep slimCstress can lead to fake hungerDexercise can help one eat less4According to the passage, we can infer that _.Aexercise helps you burn calories and makes you not want to eatBspeeding up metabolic rates is helpful to lose weightCit is nicotine that regulates how much food gets consumedDdrinking water is good to reduce the stress5The purpose of the text is _.Ato introduce the result of a new studyBto explain the reason why smokers become slimCto prove the possibility of being a slim nonsmokerDto tell us ways to quit smoking without gaining weight5. 解析：选D。主旨大意题。通读全文可知，文章从一项新的研究成果谈起，分析了戒烟后体重增加的生理原因，并重点介绍了几种应对方法。故选D项。BNow, its time for some brief news items.Teens Go OnlineSome 13 million children under 18 use the Internet for schoolwork, games and music according to research done by Nielsens “Netrating”The study covered Britain, Germany, France, Italy and Spain.

I hoped I could also have it. One day I saw a secondhand bicycle, that was only one hundred yuan. I asked my father the money. But he said he could only give me half of the money. He should find the other half myself. So I went to sell newspapers after the school. My father was pleased if I showed him the money a month after. He gives me the other fifty. You can imagine how much happy I was when I rode to school on my own bicycle.参考答案：.单词拼写1. abused2. mental3. effects4. strengthen5. desperate7. ashamed8. automatic.单项填空1. 解析：选A。句意：每天我们都必须面对新的挑战和问题。事实上，压力并不像常常认为的那样是一件这么糟糕的事情。stress“压力”，符合题意。assistant“助手；助理”；dilemma“(进退两难的)困境”；celebration“庆祝”。2. 解析：选D。考查动词短语辨析。句意：新的调查表明近年来学生沉迷于网络游戏的人数一直在增加。be devoted to“致力于”；be related to“与有联系”；be connected to“与相关联”；be addicted to“对上瘾的”。3. 解析：选C。ban“禁止；取缔”，ban常用于禁烟、禁酒、禁放烟火等。attack“进攻；攻击；抨击”，其宾语常是人；beg“请求；乞求”，其宾语常是人；remove“移动；搬开”，其宾语常是物。句意：有一场禁止在公共场所吸烟的运动。4. 解析：选D。句意：这是我们全家第一次一起在电影院里看电影。“Its the序数词that”结构中，that从句应用完成时态。根据主句的动词is可知此处用现在完成时。5. 解析：选A。句意：由于急切盼望着上大学，这个年轻人全身心地投入到学习当中去。be desperate for“渴望做事”。形容词短语作状语，故选A项。6. 解析：选B。feel like“想要；愿意”，后接动名词形式。would like“想要；情愿”，后接不定式；would rather“宁愿；情愿”，后接动词原形；had better“最好”，后接动词原形。句意：病了好几天，她不想吃任何东西。7. 解析：选A。decide是“决定；决断；判断”的意思，接名词时表示make a choice about what you are going to do; decide on“就某事做出决定；选定”，宾语往往是已确定的事；choose表示从中“选择”；determine表示“确定；决心并坚持”。句意：决定人类命运的是人民。8. 解析：选B。考查动词词义辨析。stop“停止”；quit“离开”；part“分手”；get down后需接to。句意：那年轻人离开了他的工作找了更好的职位。9. 解析：选D。every time本身可作从属连词，直接引导从句，故只有D项是正确的。10. 解析：选D。考查soadj.a/an单数可数名词that从句。such a/an形容词单数可数名词that从句。.阅读理解1. 解析：选A。推理判断题。根据第二段可知，在尼古丁的作用下，调节食欲的神经元失控，故归根结底，是尼古丁“改变”了人们的食欲。2. 解析：选D。推理判断题。根据上下文语境可知，将来，发胖不再成为人们迟迟不肯戒烟的原因，但我们也没理由一直等到将来(新药研制出来再去戒烟)，即：现在我们也有办法在戒烟的同时保持体形，故选D项。3. 解析：选A。细节理解题。由文章倒数第三段To improve metabolic rates . make half of those glasses ice water.可知，A项正确。4. 解析：选B。推理判断题。由第六段第三句可知，运动既可以消耗热量而且可以在你不真正饿的情况下阻止你进食，而非使你不想进食，故A项错误；由第四段第二句可知，加强新陈代谢可以帮助减轻体重，故B项正确；由第二段第二句可知神经元帮助调节消耗的食物量，而非尼古丁，故C项错误；第六段提到运动是一种很好的减压方式，可知D项是张冠李戴。6. 解析：选C。由第一则新闻第二句可知瑞典没有被提到。7. 解析：选D。由第三则新闻The activity is seen as p8. 解析：选C。出题句为The Florida High School, the states only online school, has 250 students who are taking classes at home by computer.。9. 解析：选B。由文章第四则新闻中的第四句可得出答案。10. 解析：选A。由British author JK.Rowling, mother of magic boy Harry Potter, will do an Internet interview about her new book “Harry Potter and the Halfblood Prince” on June 26.可以得出答案。. 短文改错答案：第一句：friendfriends第二句：itone第三句：thatwhich第四句：the money前加for第六句：HeI第七句：去掉the第八句：ifwhen; afterlater第九句：givesgave第十句：去掉much
