【语篇解读】少吃食物能让人长寿，你相信吗？科学家正在做实验来证明这一点。
1．D。国家健康协会的一项研究表明：减少30%的卡路里似乎有助于减缓猴子的衰老几率。根据下文“The study has shown that …”可知，show“表明”符合上下文语境。remark评论；believe相信；cau促使，导致。
2．B。appear to do sth.“似乎做某事”。其他选项不符合上下文逻辑关系。
3．B。这项研究的结果为“少吃，人可能长寿”提供了“新”的依据。
4．A。根据常识可知，是人的“均衡的”饮食。
5．C。卡路里的减少导致动物有个较低的温度。根据常识可知，是“拥有”更低的体温，而不是“生产、给出习惯的养成、改变”。
6．B。新陈代谢慢，衰老生理变化“更少”，符合语境。
7．A。在“国家抗衰老研究中心”从事研究的人当然是“科学家”。
8．D。对老鼠进行的实验“也”可运用于猴子。
9．B。对于后面的情况“我们知道、了解”。其他选项不符合上下文的逻辑关系。
10．A。根据前后的逻辑关系可知，应用if表示条件。
11．A。根据上下文可知，这个实验是证明“吃得少，长得慢，活得长”的关系的四君子汤祛湿，所以正确答案是A项。上文的“live longer”为重要依据。
12．C。少吃东西，老鼠可以活得更久，不“常”得病。frequently频繁地；carefully小心地；obviously明显地；definitely清楚地，明确地。
13．B。猴子也是以同样的“方式”做到反应，所以用in the same way。
14．A。同样的生理变化也可能发生在猴子身上。take place发生，举行；work out算出；pick up拾起，搭载；cut down削减。
15．C。“其他的”生化检测也表明，少吃对猴子是“健康的”。
16．A。根据上文对研究的表述可看出，“少吃”对猴子是“健康的”。其他选项不符合上下文逻辑关系。
17．D。这项研究涉及200只猴子，所以应该是在“继续”。
18．A。猴子的食物包含所有“所需的”维生素，其他选项不符合上下文逻辑关系。require需要；refer涉及，谈到，查阅。
19．C。句中的两个宾语从句是转折关系，所以用but连接。
20．B。因为是做实验，有一组猴子在食量方面是受到“控制”的。

The effects of coffee consumption on health have long been a subject of conflict and uncertainty．Since the 1980s, some have spoken out against coffee as harmful to health, while others have welcomed coffee for its suppod benefits to health．
According to a scientific report, mild coffee consumption, three to five cups per day, can be taken as a healthy dietary pattern, along with other healthful behaviors．The report also says that coffee consumption helps reduce the risk of heart dia and it protects against Parkinson's dia．
According to Dr．Donald Hensrud of Mayo Clinic, high consumption of coffee has health risks．Dr．Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body．Some studies said that drinking two or more cups of coffee daily can actually increa the risk of heart dia in the people．
According to conclusions from a recent study led by Dr．Gregory Marcus, a doctor from the University of California San Francisco, daily moderate consumption of caffeine, less t
han 4 cups, is not associated with the issues．
Until the scientific community reaches a general agreement on the effects of coffee consumption on human health, it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks．
