龙人图书快乐假期暑假作业郑州大学出版社系列答案【题目】
We all know the strange feeling of watching the time change on a clock. You never really see it change because the hands move so slowly. But, of course, the time is changing all the time.
Human faces, like clock faces, are also changing. And like clocks, the changes take place too slowly to be noticed. Over many thousands of years, though, huge changes are possible. For example, the human brain is three times as large as it was thousands of years ago. Our faces became fatter, and began to think more.
If our heads became larger in the past, how will things change in the future? Unlike the changes of a clock face, the changes in human faces are very difficult to predict(预测). One of the main reasons for this is the way in which we can now control parts of nature. Hundreds of thousands of years ago, all changes were natural, but now we can actively choose paths for our own evolution(进化).
A US artist named Nickolay Lamm has recently offered an idea. It is what human faces may one day look like. The designs, inspired（受启发)by his conversations with the scientist Alan, show humans with larger heads and eyes. In particular(特别的), Lamm predicts the forehead may be larger because of increasing usage of the brain.
Just a few hundred years ago, most humans were working in the fields. However, nowadays more and more people receive education. These are just predictions, and no one can be sure how human beings will become in the future. But with such huge changes in our environments, it seems likely(很可能)that we will not look the same in the future.
