My legs don't do much because I have a serious disease. They just sit there and look pretty. When people look at me, they only see the chair - my wheelchair. I've been in one since I was 3 years old. And it doesn't matter if I graduate at the top of my class and go to law school. To some, I'll always be the girl in the chair.

　　But I don't think of myself as the kid who can't walk. Most of my friends don't even notice the chair anymore. I'm just the girl they've been friends with. My friends are good at lifting me in and out of my small car when we go to the movies. We even took the car to the dance. One of the boys helped me out of the car and all the girls helped me to fix my dress. Even in the crowded school elevator, there's always someone around to carry me.

　　There are a lot of things I can't do for myself, such as lifting my arms, dressing myself, and feeding myself. Even so, I do very well at school and I always tell myself that I'm just like any other kid in my school.

　　The truth is that my parents raised me to be proud of my disability (残疾). There are plenty of things I wish I could do differently. I wanted to be a doctor. But that's not going to work out. So I'll be a lawyer (律师) instead. I also wanted to dance and play soccer. My parents taught me that I'm like this for a reason - to educate people and show them that this disease affects (侵袭) my bones - not my brain. My friends Erica once said to me，"Kennedy, you're not disabled. You just can't walk."

　　What will man be like in the future - in 5,000 or even 50,000 years from now？We can only make guesses, 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 obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively a short period of time, so we may assume 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. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones！This is likely to bring about a physical change to the head, in particular, the forehead will grow larger.

　　Nowadays our eyes are in constant use. 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 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 because they are used a great deal in modern life.

But 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 sexes are likely to be
