Tears are nature's way of making us feel more comfortable． When our eyes is made uncomfortable by some small pieces of pollution ， or when we are cutting onions， or when we are exhausted and "red-eyes" from over work and late hours， tears form in our eyes to clean and refresh them． Tears are also a sign of strong emotion． We cry when we are sad and we cry when we are happy． And tears seem to be uniquely human． We know that animals also experience emotion fear， pleasure， loneliness， but they do not shed （流） tears． Biologically speaking， tears are actually drops of saline fluid， which is a little bit salty， produced by a gland （腺） in the body． Because salt is an important component， tears may actually constitute the most conclusive evidence that the human animal is the end product of a long evolutionary process that began in the sea． And it is clear that， in addition to the emotional benefits， the shedding of tears has a specific biological function as well． Through tears， we can eliminate from our body certain chemicals which build up in response to stress and create a chemical imbalance in the body． Crying actually makes us feel better by correcting that imbalance and making us feel good again． And thus the emotional and the biological functions of tears merge （合并） into one and make us even more "human" than we would otherwise be．（1）According to the passage， human beings may have originated in ____ ．A．the seaB．the saltC．chemicalsD．animals（2）Which of the following is NOT a function of tears？ ____ A．Biological．B．Emotional．C．Political．D． Chemical．（3）According to the article， which of the following is unique to humans？ ____ A．The feeling of loneliness．B．The state of feeling good．C．The ability to shed tears．D．The feeling of fear．（4）The underlined word "eliminate" probably means ____ ．A．addB．produceC．replaceD．remove（5）Which of the following is the best title of the passage？ ____ A．Tears are a sign of strong emotion．B．Tears are always making us feel more comfortable．C．Tears are uniquely human．D．Tears have certain biological function．
Tears are nature's way of making us feel more comfortable． When our eyes is made uncomfortable by some small pieces of pollution ， or when we are cutting onions， or when we are exhausted and "red-eyes" from over work and late hours， tears form in our eyes to clean and refresh them．
Tears are also a sign of strong emotion． We cry when we are sad and we cry when we are happy．
And tears seem to be uniquely human． We know that animals also experience emotion fear， pleasure， loneliness， but they do not shed （流） tears．
Biologically speaking， tears are actually drops of saline fluid， which is a little bit salty， produced by a gland （腺） in the body． Because salt is an important component， tears may actually constitute the most conclusive evidence that the human animal is the end product of a long evolutionary process that began in the sea．
And it is clear that， in addition to the emotional benefits， the shedding of tears has a specific biological function as well． Through tears， we can eliminate from our body certain chemicals which build up in response to stress and create a chemical imbalance in the body． Crying actually makes us feel better by correcting that imbalance and making us feel good again． And thus the emotional and the biological functions of tears merge （合并） into one and make us even more "human" than we would otherwise be．
（1）According to the passage， human beings may have originated in ____ ．
A．the sea

C．chemicals

题目解答
答案
1．A．细节理解题．根据第四段的…tears may actually constitute the mostconclusive evidence that the human animal is the end product of a long evolutionaryprocess that began in the sea，可知，眼泪可被视为是人类是海洋生物经过了漫长的进化过程的最终产物．故选A．
2．C．细节理解题．根据第三段可知，眼泪可以表示情绪的变化．根据第四段可知，眼泪是生物功能的产物．根据最后一段可知，眼泪可以平衡身体内化学物质．故选C．
3．C．细节理解题．根据第三段的 And tears seem to be uniquely human． We know thatanimals also experience emotion fear， pleasure， loneliness， but they donot shed tears可知，动物也会有恐惧、愉悦、孤独等情绪，但他们不会流眼泪，因此眼泪是人类独有的．故选C．
4．D．词义猜测题．根据划线词所在的句子，通过流眼泪，我们可以把身体内一些与压力有关的化学物质排出去，从而达到体内化学物质的平衡，由此推知eliminate的意思是去除．故选D．
5．B．标题概括题．本文从生物学、情绪、化学三个方面指出了流眼泪是使人感觉更舒服的一种自然方法，故选B．
