What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time.

Let us take an example. Man, even five hundred years ago, was shorter than he is today. Now, on the average, men are about three inches taller. Five hundred years is a relatively (相对地) short period of time, so we may suppose that man will continue to grow taller.

    Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity (容量.) As time goes on, however, we shall have to use our brains more and more and finally we shall need larger ones! This is likely to bring about a physical change too. The head, especially the forehead, will grow larger.

    Nowadays our eyes are being used too much. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger.                      

    On the other hand, we tend (有…的趋势) to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive (敏感的) because they are used a great deal in modern life.

    What about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both men and women are probably to be hairless!

    Perhaps, all this gives the impression that future man will not be a very attractive (有吸引力的) person to look at! This may well be true. All the same, besides these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and feelings similar to our own.

My Favorite Animal

On March 9, Kiska died（去世） at 47. She lived in a park in Canada for more than ten years. When she was three（冰岛水域） in 1979. Then they went to Canada. They lived there together for a few years. In 1985, Keiko went to Mexico. He even played a role in the movie Free Willy in 1993. After that, he went back to the ocean.

Kiska was not that lucky. She did not go anywhere. In her lifetime, she had five babies, but all of them died very young. This made her very sad. If whales live in the wild（野外）（水箱） went back to the United States in 2011. From then on, she was there on her own. 

About 4 years ago, a bill（议案） passed in Canada. The bill banned（禁止） the whole country from raising whales. But it was too late for Kiska. The bill could not protect her because she was already in  th tank.

Most of us need friends, but some of us do not know how to make friends. My teacher Mr. Smith gave me some advice

{#blank#}1{#/blank#} you make friends, you must decide who you want to choose to be your friends. Most people like to have friends who like to do the same things {#blank#}2{#/blank#} they do. Think about your favorite things and try talking to your classmates about your {#blank#}3{#/blank#} hobby.

The quickest way to make {#blank#}4{#/blank#} friend is to smile. If you do so, people think you're friendly. At first, it may not be easy to smile. However, remember that nobody {#blank#}5{#/blank#}( like) a long or cold face

One easy way to talk with people is to say something nice about them. Just think about {#blank#}6{#/blank#} you feel when someone says something nice about you. Doesn't it make you want to keep {#blank#}7{#/blank#} ( talk) with a person?

Ask {#blank#}8{#/blank#}( you) new friends questions about them. Who's their favorite singer? Where do they live? Who's their teacher or what do they do after school? Sometimes you can make friends {#blank#}9{#/blank#} ( easily) if you ask more questions.

After making some friends that share the same interests. It's always fun {#blank#}10{#/blank#} ( play) or do something together. And this is the right way to make a friendship closer.

There are many ways to help improve your health like eating healthy food. Taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are，the longer sleep you need. But regardless of（不管）age，some people need to sleep more while for some a few hours is enough. 

 ① .  According to the World Health Organization over half the people in the world may be sleep﹣deprived(睡眠不足的). Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100, 000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure. 

 ② . Why are so many people sleep-deprived? Part of the reasons may be cultural. In the American culture, people put a higher value on work than on sleep. In fact, people who sleep a lot are usually seen as "lazy". Also, you can sometimes hear some people say proudly that they don't have much time to sleep. They only sleep four or five hours a night. It seems that the less you sleep，the more work you'll do. 

 ③ . How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas, an expert in sleep. He says, "Sleep is like a credit （信用卡） card. When you sleep less, you are only borrowing time. You always have to pay it back. The more hours you don't sleep, the more hours you should sleep to 'pay back' the hours on your 'sleep credit card. '"

 ④ . For those who value work more than sleep, they should listen to what a famous person once said. " Don't think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more. "
