36、e accumulated will betray how we ate. 可知，人们在年底大吃大喝之后开始节食，主要是因为害怕夏天来了会暴露出自己臃肿的身材。2. A 事实细节题。根据第四段has identified a precise link between a particular kind of bacteria and unusual weight gain.可知，肥胖和某一种特殊的细菌之间有密切的联系。3. D 推理判断题。根据倒数第四段“The list of diseases that they may play a role in is just growing and
37、growing,”以及.arent yet able to conduct cause-and-effect studies. 可知科学家发现细菌可能与很多疾病有关联。4. B 事实细节题。根据文章倒数第二段researchers tried to cure the patient by feeding him a specialized nutritional liquid food to decrease the bacteria in his guts to ignorable amounts.可知，细菌数量的减少可以使体重下降。5. C 主旨大意题。从文章多次出现found, disc
38、overed 可以看出本文主要讲的是一项新的医学发现。很多考生选了D，误选的考生可能他们不知道该文讲的是肥胖的原因，而不是肥胖的结果。(B) 本文作者主要告诉我们，吃正确的食物、保持足够的睡眠和有规律的运动是保持健康最重要的三种方式。1. D 事实细节题。根据首段There are three things that a person can do to help stay in good shape: eat the right foods, get enough sleep and exercise regularly.可知选D。2. A 事实细节题。由文章第一段中It is import
39、ant to remember that the body needs proper care in order to be healthy.可知A项正确。3. B 推理判断题。根据第二段最后一句However, dont overeat. It is not healthful to be overweight.和第三段If you dont get enough sleep, you feel tired and irritable. You have no energy. Be sure to allow yourself from seven to nine hours of slee
40、p each night.可推知B项正确。4. D 猜测词义题。根据上下文语境可知，如果你自己有足够的睡眠，那么身体和思维这两个方面会有什么样的效果。显然sharp的感情色彩必须和strong and refreshed一致。B和C可首先排除；A项是对sharp的基本释义，并不符合文章语境。故选D符合上下语境。sensitive在此意为“灵敏的，敏锐的”，与sharp一致。5. C 主旨大意题。A、B、D都过于片面，只有C项具有总领文章的概括性。根据文章可知，eat the right foods, get enough sleep and exercise regularly是保持健康(St
41、aying Healthy)的三种方式。故选C合适。二、完形填空本文作者向我们介绍了缺乏睡眠给记忆力带来的影响并建议我们在午饭后休息一会，以补充睡眠。1. C 根据下文，特别是最后一段中的If it is 19 , you should sleep for a short time after lunch可知，研究人员是建议在白天睡个短觉。故选C合适。2. A 根据第一段American researchers或者第三段a lead researcher said.可知选A。属于原词复现。3. C 根据空后的They kept the rats可知选C。同样属于原词复现。4. D 由上文可知，
42、研究人员为了找出缺乏睡眠对记忆力带来的影响，他们用田鼠做试验，他们让田鼠保持清醒达72个小时，言下之意是让田鼠缺乏睡眠，看看会发生什么样的情况。同时也通过这个事实发现一些问题。故选D符合上下语境和逻辑。5. B 结合四个选项和空后的stress hormones to get together可知，此处是指：缺乏睡眠使压力荷尔蒙在一部分脑中聚集。习惯搭配causeto意为“使发生/做”，符合语境。C和D项可首先排除；A项made干扰性较大，但make后常接动词原形，即：makedo。6. B 根据下面的helped new memories可知此处肯定是指在脑中才能与memories有联系。7
43、. A 根据前文中sleep deprivation 5 stress hormones to get together in a part of the 6 , which的which(指代前面缺乏睡眠引起压力荷尔蒙这个情况)造成帮助新的记忆力的细胞的增长减缓。只有选A才符合上下语境和逻辑。8. A 由本段前面的sleep deprivation is stressful可推断，缺乏睡眠会让记忆力变弱。故选A合适。9. C 结合空后的to earlier studies可推出类似的实验以前肯定做过，也得出过相似的结论。故选C合适。10. D 根据空前的sleep-deprived peopl
44、e可知选D合适。11. C 本句是将缺乏睡眠的状态和睡眠正常的状态进行对比。表正常状态常用normal，故选C。12. C 由空后的is bad for memory不难推断出答案选C最合适。lack of意为“缺乏”。13. D 根据本文主要内容，主要就是讲睡眠和记忆力之间的关系，因此不难知道此处选D符合文意。14. D 根据上文拿老鼠做实验的实例可知答案选D正确。15. B 根据空前的is usually long和空后的staying awake for several weeks可知，两者的时间都很长。斟酌四个选项，只有B项是表两者相似的，equal to意为“”相当于。16. A 文
45、章多处提到。属于原词复现。17. B 思考四个选项并考虑句意：既然你现在为进入大学而忙着学习，你最好每天有足够的睡眠。因此此题选A最佳。entry into意为“进入”。entry为名词。18. D 根据本句意和上下语境逻辑可知。19. B 结合本句句意不难知道答案选B正确。其他选项显然逻辑不符合。20. A 结合空后的unexpected可知，此处指饭后休息一下，也许结果是令人惊喜的和意想不到的好。故选A最符合句意和文意。三、语法填空本文主要介绍保护视力的方法和技巧。1. As 空后是两个分句，故一定是填连接词。再根据句意，此处显然表原因，故填As引导原因状语从句。引导词位于句首引导原因状语从句时，常用As。注意首字母要大写。2. or 空的前后是两个短语by medicine
