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（唯獨(dú)）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 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.

68．According to the passage, human beings may have originated（起源于）in________.

A．the sea              B．the salt         C．chemicals       D．a(chǎn)nimals

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．a(chǎn)dd             B．produce        C．replace         D．remove

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.
1  
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 (鋸掉) 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.
There is a time to weep and a time to laugh.    5   And you’ll smile at the end.

A．She was learning to wear an artificial leg.
B．And her laughter helped her cope.
C．You would be happy if you find reasons to laugh.
D．Betsy laughed heartily about the incident.
E. But do you also laugh during the difficult times?
F. If you can laugh even when the going gets rough, you’ll make it.
G. She learns that all cancer survivors prefer to laugh.

The Value of Tears
Tears can ruin make-up, bring conversation to a stop, and give you a runny nose. Tears leave you embarrassed and without energy. Still, crying is a fact of life, and your tears are very useful. Even when you’re not crying, they make a film over the eye’s surface.  【小題1】
When tears fall, they reduce stress. But we tend to fight them for all sorts of reasons. “People worry about showing their emotions（情緒）, afraid that once they lose control they’ll never get it back.”  【小題2】 After we cry, the  feelings that caused the tears often disappear.
Sometimes people become much stressed and can’t cry. Whatever emotion they are feeling — shock, anger, fear, or sadness— is being held back.
But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry.  【小題3】 Patients practice crying just to become used to expressing emotions. She suggests safe, private places to cry, like under the bedcovers or in the car. Crying is a way of ease tension, but people don’t like it when others cry because it makes them tense.【小題4】 And they’ll do just about anything to make you stop.
In certain situations, such as at work, tears are not appropriate. It’s good not to cry during a tense business discussion.  【小題5】You should also act out the whole situation again and be as noisy and angry as you like. It will help you feel better. “And,” she adds, “Once your tears have taken away the stress, you can begin to think calmly of ways to deal with the problem.”
Tears are a sign of our ability to feel. If you find yourself near someone crying, deal with it. And never be afraid to cry yourself.

A．They too may be holding back a need to cry.
B．They cry for different reasons.
C．She gives crying exercises.
D．It contains a chemical against infection（炎癥）.
E. The fact is no emotion lasts forever.
F. It forms in response to the stress on the surface of the eye.
G. But once you’re safely behind closed doors, don’t just cry.

閱讀表達(dá) （滿分 10 分）

(1)The half-empty coffee cups, still standing next to their plates, tell of a morning like others. And yet, that grey covering of dust that everything wears tells a different story: it tells of screams, tears, confusion, terror and blood.

   (2)Now the restaurant in the World Trade Center will never again serve breakfast. And never again will all those people go there to eat or work --- those people of America whose faces have entered our hearts. So many people whose faces we associate with life and liveliness _______ tonight. So many words remain unsaid, and so much happiness has been destroyed. In their places are tear-stained faces. My generation has seen this. On Monday, a fight with my sister and a bad grade seemed to be the biggest problems in the world. Tonight, so many people across the country know that America’s pain is at its worst ever. We have read about World War II, and we have seen the black-and-white pictures. But to most students, that’s an event on a textbook page that would never happen today.

  (3) After all, this was a time of peace and wealth --- the United States was powerful and successful. There would be no more wars, and we were lucky to live in such a time. But when those planes hit; when firefighters with terror on their faces ran among the parts of the buildings that had fallen; when people screamed for their family members; when history was unfolding before our eyes, in full, clear colour ---- then we knew the world had been changed.

  (4) Everything that had happened in the past seemed to take on new life through September 11, 2001. And when they say this is the worst wound in American soil, I say, I thought this place was an empire. And I say, I thought this was a time of peace. And I say, I thought we were safe.

  (5) Knowing how many human beings turned to ashes in a second, and seeing some jumps from the buildings, I know that my generation is growing up in a world where mankind can still be evil. But seeing those heroes risk lives among the castle-like ruins, and seeing the eager blood donors at the hospitals, my generation has learned that tears are allowed, that mankind can also be beautiful, and that the ghost of evil will never defeat the spirit of good.

B

Snow can be very beautiful. When snow covers everything around you , the world looks like a “Winter Wonderland”. That is the name of a very popular song about winter. Richard Smith and Felix Bernard wrote the song in 1934.

But winter is not always such a beautiful and happy time. It is cold outside.The wind blows and makes it even colder. The days are shorter and darker. The sun rarely shines.

Many people believe the glare from snow causes snow-blindness. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of “snow light”. The United States Army has now determined that glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of barren (少植被的) snow-covered terrain (地形). So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature eases this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs (模糊), then is obscured (遮蔽), and the result is total, even though temporary, snow-blindness.

Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop scouring the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white terrain is overcome.

1. To prevent headaches, watering eyes and blindness caused by the glare from snow, dark

glasses are _________.

A. indispensable and essential   B. useful                       C. ineffective      D. available

2. When the eyes are sore tears are produced to _________.

A. balance the pain                                                       B. treat snow-blindness 

C. clear the vision                                                            D. loosen the muscles 

3. Snow-blindness may be avoided by _________.

A. concentrating on the solid white terrain

B. searching for something to look at in snow-covered terrain

C. providing the eyes with something to focus on

D. covering the eyeballs with more fluid 

4. The scouts shake snow from evergreen bushes in order to _________.

A. prevent the men behind losing their way 

B. beautify the landscape of the terrain

C. warm themselves in the severe cold

D. give the men behind something to see

5. A suitable title for this passage would be _________.

A. nature's cure for snow-blindness       B. snow-blindness and how to overcome it

C. soldiers marching in the snow          D. snow vision and its effect on eyesight
