     Olaf Stapledon wrote a book called First and Last Men, in which he looked millions of years ahead.  

He told of different men and of strange civilizations, broken up by long dark ages in between. In his view, what is called the present time is no more than a moment in human history and we were just the First

Men. In 2 000 million years from now there will be the Eighteenth of  "last men". 

     However, most of our ideas about the future are really very short-sighted. Perhaps we can see some

possibilities for the next fifty years. But the next hundred? The next million? That's much more difficult.

     When men and women lived by hunting 50 000 years ago, how could they even begin to picture

modem life? Yet to men of 50 000 years from now, we may seem as primitive(原始的) in our ideas as

the Stone Age hunters to us. Perhaps they will spend their days gollocking to make new spindles, or

struggling with their ballalators through the tribes. These words, which I have just made up, have to

stand for things and ideas that we simply can't think of.

     So why bother even to try imagining life far in the future? Here are two reasons. First, unless we  

remember how short our own lives are compared with the whole human history, we are likely to think

our own interests are much more important than they really are. If we make the earth a poor place to live

on because we are careless or greedy or quarrelsome, our grandchildren will not bother to think of

excuses for us. Second, by trying to escape from present interests and imagine life far in the future, we

may arrive at quite fresh ideas that we can use ourselves. For example, if we imagine that in the future

men may give up farming, we can think of trying it now. So set your imagination free when you think

about the future.

A. serves as a description of human history

3. Spindles and ballalators are used in the text to refer to         .

A. tools used in farming
