Question

People laugh and people cry. But it is thought that emotions such as anger, or joy, typically make Americans feel uncomfortable and embarrassed. The shedder of tears(落泪者) is likely to apologize, even when a great tragedy was the cause. The observer of tears is likely to do everything possible to put an end to the emotional tears. But judging from recent studies of crying behavior, both those responses to tears are often inappropriate and may even be counterproductive (适得其反).

Humans are the only animals clearly known to shed emotional tears. Since evolution has given rise to few purposeless physiological responses, it is logical to assume that crying has one or more functions that increase survival.

Although some observers have suggested that crying is a way to ask for assistance form others (as a crying baby might from its mother), the shedding of tears is hardly necessary to get help. Vo-cal (出声的) cries would have been quite enough, more likely than tears to gain attention. So, it appears that there must be something special about tears themselves.

Indeed, the new studies suggest that emotional tears may play a direct role in easing stress. University of Minnesota researchers who are studying the chemical composition of tears have recently separated two important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to emotion. Tears shed because of exposure to cut onion would contain no such substance.

Other researchers are looking into the usefulness of tears as a means of diagnosing human ills and monitoring drugs. At Tulane University’s Teat Analysis Laboratory Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse, to study the causes of "dry eye" syndrome(综合症) and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.

1.What does the phrase "both those responses" in Paragraph 1 refer to?

A. Crying out of sorrow and shedding tears for happiness.

B. The embarrassment and unpleasant feelings of the observers.

C. Linking illness with crying and finding the chemical composition of tears.

2.It is known from the first paragraph that____.

A. shedding tears gives unpleasant feelings to Americans

B. crying may often result in tragedy

C. crying usually wins sympathy from other people

D. one who sheds tears in public will be blamed

3.What does the author say about crying?

A. It is a pointless physiological response to the environment.

B. It must have a role to play in man' s survival.

C. It is meant to get attention and assistance.

D. It usually produces the desired effect.

4.From the passage we can infer that____.

A. it is unnatural for people to shed tears

【解析】

试题分析：人们开心的时候会笑，不开心的时候会哭泣。但是，生气、欢乐等情绪会让美国人感到不舒服。研究发现，因为某种情感而流出的泪水能够减轻压力。研究人员在情绪性的泪水中发现了两种特殊的化学物质，而切洋葱时流的泪中不含这两种物质。

1.The shedder of tears(落泪者) is likely to apologize,...The observer of tears is likely to do everything possible to put an end to the emotional tears.”可知，划线部分指的是流泪者的道歉和他人的安慰，故选D。

2.The shedder of tears(落泪者) is likely to apologize, even when a great tragedy was the cause.”可知，即使是因为很悲惨的事情落泪，只要被他人看见，落泪者就会道歉，说明美国人认为眼泪会给他人带来不好的感受，故选A。

3.crying is a way to ask for assistance form others...Vo-cal (出声的) cries would have been quite enough, more likely than tears to gain attention.”可知，哭是求助的一种方式，但是，仅有出声的哭喊就足够了，喊叫声比眼泪更有可能引起注意，说明哭是一种求助和引起注意的方式，故选C。

4.emotional tears may play a direct role in easing stress...Both chemicals are found only in tears that are shed in response to emotion. Tears shed because of exposure to cut onion would contain no such substance.”可知，研究显示，情绪性的眼泪能够减轻压力，情绪性的眼泪中含有两种特殊的化学物质，受到洋葱的刺激而流的眼泪中不含这两种物质，说明情感性的泪水能减轻压力，故选B。
