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

Let us take a clear example. Man， even five hundred years ago， was shorter than he is today. Now on average， man is about three inches taller. Five hundred years is relatively a short period of time， so we may imagine that man will continue to grow taller.

Again， in the modern world we use our brain a great deal. Even so， we still make use of only about 20% of the brains capacity （容量）. 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 too： the head， in particular the forehead， will grow larger.

Nowadays our eyes are in frequent 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 mans 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 sometime because it does not serve a useful purpose any longer. In the future， then， both men and women are likely to be bald （秃头的）！

Perhaps all this gives the impression that future man will not be a very attractive creature to look at！ This may be true. All the same， even though with these changes， future man will still have a lot in common with us. He will still be a human being， with thoughts and emotions similar to our own.

B

Theres more to learning math than paying attention in class， according to recent research. It shows that kids math performance may be better for those with a natural gift for sensing numbers.

Scientists showed a number of dots （小圆点） for a very short time—some blue， others red—and asked someone to determine which group of dots was more. The dots appear and disappear so quickly that it becomes impossible to count， so the numbers have to be sensed instead.

In the experiment， researchers studied 174 children between 3 and 5 years of age to judge their ANS （the Approximate Number System， 略估数字系统） with computer tests. Then they judged childrens math and verbal （口头的） skills through a lot of tests and asking parents to list common words in their childrens vocabulary.

Allowing for age， vocabulary size and speed of taking the test， the group still found better ANS scores to be connected with childrens early math abilities. In the past it was thought to be the result of different teaching styles， but this connection seems to already exist before kids start formal math education in school.

However， the authors of the paper admit they cannot use ANS to predict math ability easily. They said that they could not control other parts of learning， which may also have an effect.
