Shedding tears(流淚) is a natural way of making us feel more comfortable．When our eyes are made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted(精疲力竭; 疲勞) and have “red-eyes” from overwork 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 (惟獨) human．We know that animals also experience emotion ——fear, pleasure, loneliness——but they do not shed (流) tears．From this, we can conclude that tears are closely related to the emotional and biological make-up(結(jié)構(gòu)；組成) of the human species．

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 (除了) the emotional benefits (好處), 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(不平衡) in the body．Crying actually makes us feel better by correcting that imbalance and making us feel good again．And thus the emotional and biological functions of tears merge (合并) into one and make us even more “human” than we would otherwise be．

A. the sea                 B. the salt      C. chemicals     D. animals

61、Which of the following is NOT a function of tears?

A. Biological    B. Emotional    C. Political           D. Chemical

62、The underlined word “eliminate” probably mean_______．

63、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．

       Harald Kaas was sixty. His back became rounded, and he bent a little. His forehead, always of the broadest－no one else’s hat would fit him － was now one of the highest, that is to say, he had lost all his teeth, which were strong though small, and blackened by smoking. Now, instead of “deuce take it” he said “deush take it”. He had always held his hands half closed as though grasping something; now they stiffened so that he could never open them fully. The little finger of his left hand had been bitten off. According to Harald’s version of the story, the fellow swallowed the piece on the spot.

       He was fond of showing off the left part, and it often served as an introduction to the history of brave adventures, which became greater and greater and greater as he grew older and quieter. His small sharp eyes were deep set and looked at one with great intensity. There was power in his individuality. He has no lack of self-respect.

       His house, raised on an old foundation, looked out to the south over many islands; farther out were more islands and the open sea. Its eastern wing was barely half furnished, and the western inhabited by Harald Kaas. These wings were connected by a gallery, behind which were the fields and woods to the north.

In the gallery itself were heads of bears, wolves, foxes and lynxes and stuffed birds from land and sea. Skins and guns hung on the walls of the front room. The inner rooms were also full of skins and filled with the smell of wild animals and tobacco-smoke. Harald himself called it “man-smell”; no one who had once put his nose inside could ever forget it. Valuable and beautiful skins hung on the walls and sat, and walked on skins, and each one of them was a subject of conversation. Harald Kaas, seated in his log chair by the fireside, his feet on the bearskin, opened his shirt to show the scars on his hairy chest (and what scars they were) which had been made by a bears teeth, when he had driven his knife, right up to the end, into the monster’s heart. All the tables, and cupboards, and carved chairs listened in their silence.

68．Who or what most probably bit harald Kaass’ little finger off?

       A．On of his fellow hunters

B．An adversary in a boxing match

C．A wild animal 

D．One of his hunting dogs
