3 . Recently we carried out a survey of 1,000 people from different countries to find out what they think _______will be like in the future. The results clearly show both our _______and fears.

The survey suggests that_______ — one of the most important human relationships — will change greatly. People will make friends through the Internet. Computers will become really_______by 2050. Even now, some people describe them as their best friends! Others, _______, say that we will become much more isolated (孤立的) from each other _______we will have little real human communication.

4 . What will man be like in the future? How about in 5,000 or even 50,000 years from now? We can only make a________, of course, but we can be sure that he will be different from________he is today, for man is slowly________all the time.

Let us take an example. Man, even 500 years ago, was________than he is today. Now, on average, men are about three inches taller. 500 years is a relatively short period of________, so we may guess that man will________to grow taller.

Again, in modern world we use our________a great deal. Even so, we still________only about 20% of the brain’ s capacity (容量).As time________, however, we shall have to use our brains more and more --and finally we shall need even larger ones! This is likely to________a physical change, too. The head,________, the forehead, will grow larger.

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

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