As we all know, nature has supplied every animal except man with some covering for his body such as fur, feathers, hair, and shells as a thick hide. But man has nothing but a thin skin.
If someone were to ask you, "Why did human beings start to cover their bodies with clothes?" most would answer, "To keep themselves warm, of course."
It is only when we begin to think about it a little that we realize that clothes are worn for a great many reasons that have nothing to do with our need for warmth at all.
For example, we wear clothes to some degree in order to decorate ourselves－to make ourselves, if possible, look more dignified (尊严) or nicer.
Clothes of a special kind are often worn to show that the wearer has authority or power. The individual wearing them is treated with respect because he occupies a certain office. The judge on the Bench, for example, might look a very ordinary and unimpressive figure without his wig and gown. Clothes are an important part of ceremony, whether it is connected with belief, the law, parliament, and royalty, the fighting forces or the state. How very different the Queen's Coronation ceremony (加冕仪式) would have looked without the robes, coronets and the cloth of gold.
Sometimes, even in some modern countries people wear some article of clothing, or some jewel, because they believe that it will bring them luck or protect them from evil or illness, or because it is connected with their beliefs.
None of these reasons for wearing clothes－to decorate ourselves, to show our position in the world, for ceremonial purposes, for "luck", to give ourselves dignity and authority－have anything to do with our need for warmth.
65.From the passage we know that wearing clothes is man's basic necessity to________.
A. protect skin    B. show beauty      C. keep warm    D. bring luck
66.According to the passage, the judge wearing special clothes on the Bench________.
A. looks nicer      B. looks different        C. shows wealth         D. shows power
67.Even in modern countries, sometimes people wear certain clothes because________.
A. they believe that they will get protected from bad luck and illness
B. it has something to do with their wealth
C. they want to show their power
D. they enjoy wearing such kind of clothes
68.The author's purpose in writing this article is to tell us that clothes are worn________.
A. for ceremonial occasions B. for many other reasons besides warmth
C. to keep people impressive and nicer        D. to show people's authority or power       

The sun was shining when I got on No. 151 bus. We passengers sat jammed in heavy clothes. No one spoke. That’s one of the 36 rules. Although we see the same faces every day, we prefer to 37 behind our newspapers. People who sit so close together are using those thin sheets of newsprint to keep their 38.

As the bus came near the Mile, a 39 suddenly rang out, “40! This is your driver speaking.” We 41 the back of the driver’s head. “Put your papers down. All of you.” The 42 came down. “Now, turn and face the person next to you. Go 43.” 

Surprisingly we all did it. Still no one smiled. I faced an older woman, her head wrapped in a red scarf. I saw her 44 every day. Our eyes met. We waited for the next  45 from the driver. “Now repeat after me. Good morning, neighbor!”

Our voices were 46. For many of us, these were the 47 words we had spoken that day. But we said them together, like 48, to the strangers beside us. We couldn’t help 49. There was the feeling of relief(解脱) that we were not being robbed. Moreover, there was the sense of ice being 50. “Good morning, neighbor.” It was not so 51 after all. Some of us repeated it, others shook hands, and many laughed.

The bus driver said nothing more. He didn’t 52 to. Not a single newspaper went back up. I heard laughter, a warm sound I had 53 heard before in bus No. 151.

When I 54 my stop, I said goodbye to my seatmate, and then jumped off the bus. That day I was 55 off happily.

We all, at one time or another, have pretended to be a rock star, singing and dancing along to our favorite song. Most of us have done this in the privacy of our own room when we were kids and as adults, in the privacy of our homes. Me? I love to do that when I drive! I turn on the radio, find a song that I can sing along too and pretty soon my arms are in the air and I am moving along to the rhythm. Most of the time, I do this on my way to work.

　　Yes, that is true. I will be in my nice work clothes, jamming while driving or stopped at a traffic light. I get weird looks from some people and others laugh. Personally, I love to get lost in the rhythm of a song which leads me to share with you the importance of being silly!

　　The definition for the word silly, according to the dictionary is: stupid, foolish and nonsensical. I know many people do not want to look foolish. So they walk around all serious, which in all honesty, is foolish!

　　No one is perfect, I repeat: no one is perfect. I don’t care how educated, how thin, how beautiful, how simple, how frugal, how rich, and so on… No one is perfect! So why pretend to be something you are not?

Life is so short… You never know when this beautiful journey will be over, so why waste a single second on being so full of rigidity(呆板)? Here is a quote by Souza, that I think says it all and is a great recipe for life:

　　"Dance as though no one is watching you,

　　Love as though you have never been hurt before,

　　Sing as though no one can hear you,

　　Live as though heaven is on earth."

　　When we were kids, we had no idea of what limitations were and we had no care in the world so we could do things without worrying about how we appeared to others. However, as we grew up, we lost that childlike innocence.

　　So don’t lose the child that still lives within you. The next time you feel down, go turn on your favorite song, and sing and dance along like there is no tomorrow. Or watch something that makes you laugh. Laughter is the best medicine to whatever ails you and nothing is better than laughing so hard that your tummy hurts. Trust me, you will feel a whole lot better, and who doesn’t want to feel good?

1. According to the passage, what does the writer usually do?

2.What do other people think of the writer?

3. What is the writer’s opinion about the people who look very serious?

4. The writer quotes Souza to show that _______.

5.The underlined part “the child” in the last paragraph probably refers to _______.

There are several advantages in planting trees：they firm the soil，soak(渗透) up extra water and take carbon dioxide out of the atmosphere. However，it now turns out that planting trees could add to global warming. We all know that tree roots do a great job of keeping soil firmly on the ground and out of the wind's power. The problem is that some of the dust clouds play an important part in soaking up carbon dioxide.

Huge dust storms blow out over the oceans from  dry parts of North Africa and Central Asia. Tons of dust are lifted and left as a thin film over the ocean surface.

Dust from China is carried east and left in the Pacific Ocean. If a tree­planting programme there is successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked away in the ocean.

Andy，an environmental scientist has spent the past few years studying dust and says his work shows clearly the complexity of the system. For this reason the need is to focus on cutting carbon dioxide giving off rather than doing anything else.

Robert, an American scientist, has  shown that when native grassland areas are invaded by trees, carbon is lost from the soil. “We are studying why the soil carbon disappears，but one theory is that trees do a lot more of their growing above ground compared to grass, so less carbon goes directly into the soil from trees.” said Robert.

In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed by the loss of carbon from the soil below ground.

Countries that plan to fight against global warming by planting trees may have to think again. Solutions to environmental problems are often more complex than they first appear，and understanding the Earth's climate is a very great challenge.

A. huge dust storms can destroy carbon dioxide

B. planting trees could reduce global warming

A. environmental problems are more complex than expected

62．Robert's experiment proves that ________.

A. trees absorb more carbon than grass

C. less carbon can make trees grow faster

D. grassland areas should be covered by forests

63．The best title for this passage is “________”．
