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 re-flesh 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（唯独）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 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（好处）, 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.

A．the sea B．the salt C．chemicals D．animals
69．Which of the following is NOT a function of tears?
A．Biological B．Emotional C．Political D．Chemical
70．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
71．The underlined word “eliminate” probably means_______.
A．add B．produce C．replace D．remove

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Laughter and tears are part of living. But do you find enough time for laughter? I am not
asking if you experience lots of good times. Of course we should laugh during the happy times.

Erma Bombeck is known for her humorous books, but she wrote one that covered a more
serious topic: cancer in children. Erma talks with lots of children with cancer and learns an important life lesson from them. 2
She tells the experience of 15-year-old Jessica from Burlington, VT. Jessica’s leg was amputated (锯掉) at the knee because of cancer. Jessica tells about playing soccer. She kicked the ball hard and it flew off in one direction while her artificial leg flew another way. Then “the tall, pretty person that I am,” she said, “sat on the floor in laughter.”
Jessica may not have laughed about her cancer, but she laughed about dealing with its results. 3
Then there is the story of 17-year-old Betsy. She made her way to the radiation room(放射室) for
her regular radiation therapy. As usual, she dropped her hospital coat and, wearing only her birthday suit, climbed onto the table and waited. After a couple of moments she began to realize something disturbing: the extra people in the room were not the medical students she had thought, but rather painters giving an estimate on painting! 4 And like Jessica, her ability to laugh helped her to deal with one of the most difficult things a young person can endure(忍受) — cancer.

| A．She was learning to wear an artificial leg. |

| C．You would be happy if you find reasons to laugh. |
