2014年理工类阅读理解新增文章-书中第38篇

　　4. According to Choes hypothesis,

　　A an ant still smells like a living when it dies.

　　B the I am dead chemical leaves the ants body when it dies.

　　C the I am not dead yet chemical is left when an ant dies.

　　D the I am not dead yet chemical leaves the ants body when it dies.

　　5. What is the result of the test on Choes hypothesis?

　　A It proves that his hypothesis is time.

　　B Not enough evidence has been found to support his hypothesis.

　　C It shows that his hypothesis is wrong.

　　D It indicates that his hypothesis needs revising.

　　答案与题解：

　　1. C 根据文章第二段和第三段的表述，阿根廷蚂蚁身上有种化学物质，它会告诉其他蚂蚁I am dead.。文章没有说这种物质有毒，也没有说它能导致或预防死亡，所以其他三项都是错误的选择。

　　2. B keep sb. from doing sth. 这个句型的意思是：使不做，阻止去做。所以只有 B 是正确理解。

　　3. A 第三段和第四段告诉我们，蚂蚁身上会带有两种化学气味，I am not dead yet 和I am dead。这层意思分别在 B、C 和 D 中的表述出现。短文的第六段告诉我们，蚂蚁死去时，I am not dead yet的气味就离开了它的躯体，剩下的就是I am dead 的气味。I am dead的气味不是死后新产生的化学物质。所以 A 是正确的选择。
