Question

1．The chimp didn't feel well．She fell over，ignoring the other wild chimps．Finally，the sick chimp crawled over to a bush，picked some leaves and swallowed them．By the next afternoon，the chimp was as good as new!
       Biologists watching the chimp were surprised．Somehow，the plant had cured the chimp!Did the chimp know the plant would make her feel better？Or was it just a lucky accident？
       Many scientists don't think it has anything to do with luck．They're discovering that some animals seem to use plants to cure themselves．And these animals are leading scientists to new plants that could cure humans!
       Dr．Richard Wrangham，an anthropologist at Harvard University，agrees that animals may know something we don't know about forest plants．
       Wrangham got to know chimps and their diets while studying them for three years in Tanzania．"You must know a lot about an animal's feeding habits to know what it doesn't consider food，"Wrangham explains．Every morning，he saw that most chimps ate fruit near their nests．Later on，they ate on leaves．
       When he noticed chimps eating the leaves of a plant they usually ignored，Wrangham thought something interesting was going on---especially when he saw that they'd sometimes walk for 20 minutes to find the plant．Another strange thing that caught his eye was how they ate the bitter leaves．
"They swallowed the leaves whole，"explains Wrangham，noting that chimps usually chew their food well．"They seemed to rub（摩擦）the leaves around the roofs of their mouths．They closed their eyes，wrinkled their noses and swallowed slowly．"
       Wrangham wondered what could be so good about something tasting so bad．He had a chemist analyze the leaves．He discovered that the leaves contain a red oil that kills different viruses（病毒）．Later tests showed that the oil might even fight cancer and the AIDS virus!
Why don't the chimps chew the leaves？"Rubbing the leaves between the tongue and the inside of the mouth might allow the chemicals to enter the bloodstream directly，"he suggests，"instead of going to the stomach，where they might get destroyed by acids．The chimps seem to know what they're doing．"

Answer 1

分析 本篇文章属于科普文，讲述的是黑猩猩通过吃一种特殊的树叶可以治愈自己疾病，科学家们对此迷惑不解并进行了持续的研究．

解答 67．答案 A 推理判断题．由第二段"Somehow，the plant had cured the chimp!"和最后一段"Rubbing the leaves between the tongue and the inside of the mouthmight allow the chemicals to enter the bloodstream directly"可知是植物中的化学成分治愈了黑猩猩．故答案为A 
68．答案 C  细节理解题．由第五段"Youmust know a lot about an animal's feeding habits to know what it doesn't consider food，"Wrangham explains．Every morning，he saw that most chimps ate fruitnear their nests．Later on，they ate on leaves．可知了解了黑猩猩的饮食习惯后就可以判断哪些东西不是黑猩猩的食物而是药物．故答案为C 
69．答案  A  写作意图题．阅读全文可知作者的目的是讲述科学家通过观察黑猩猩的活动，发现了黑猩猩可以用吃某些植物叶子的方法治疗自己．所以讲的是一个科学家的发现．
70．答案 B  主旨大意题．阅读全文可知作者讲述的是动物治愈自己疾病的故事．

点评 科普知识与现代技术是高中课程标准规定的话题之一．此类题材的文章涉及内容广泛，如天文地理、生物医药、发明创造、计算机技术等等．这类文章的总体特点是：科技词汇多，句子结构复杂，理论性强，逻辑严谨．具体说来它有以下几个特点：
1．文章中词汇的意义比较单一、稳定、简明，不带感情色彩，具有单一性和准确性的特点．
2．句子结构较复杂，语法分析较困难．为了描述一个客观事物，严密地表达自己的思想，作者经常会使用集多种语法现象于一体的长句．
　3．常使用被动语态，尤其是一些惯用被动句式．
4．科技环保类文章在高考英语试题中出现的频率最高，一直是高考的主要测试内容，此类文章一般为说明文，但也常常夹杂着叙述和议论，并经常出现一些较新的科技名词或术语．着重从不同侧面考查学生筛选、提取、推断信息的能力．考生若经常阅读英语报刊，具备丰富的课外知识，并积累一定的时新词汇，对解读此类文章会大有帮助．
