32.Can you imagine traveling to work in a one-man submarine?Some scientists believe that some day one-man submarines will be as many as automobiles are today.A famous French driver says, "One day soon,men will walk on the ocean floor as they do on the street!" Perhaps during your lifetime people will travel,and live in the sea. If human beings want to live in the ocean,many human problems will need to be studied first. Some of these problems,similar to those of living in outer space,are pressure,lack of oxygen and weightlessness.Many questions are still unanswered.For example,can our blood make itself fit for underwater surroundings?What will happen to our muscle if we live in the water very long?Scientists are looking for answers. Perhaps in the future man will live in the sea,away from the crowded and noisy cities on land.Then sea has plenty of space,not only for floating living buildings and parks,but also for storing supplies and for underwater travel. Some scientists believe that ocean living will benefit man in more than physical ways.In the freedom and beauty of the deep sea,man may find new sources of joy.

33.Scientists all over the world are trying to make robots think.They all think it is one of the biggest challenges for them.(1)
Of course not.And that could even be dangerous because the robot might not do what the scientists want it to do.(2)
But scientists do want to make robots do more things for human beings.One recent experiment about developing "thinking robots" has made robots play football.(3)
These robots know which team they are playing for if players on the same team wear the same coloured clothes.(4)
The robot can move the ball in a suitable direction to another player on its own side.They also have a goalkeeper.It has two real eyes. (5)
Games are a good way for scientists to test robots.
A.We have seen many frightening films and books about robots controlling human beings. B.Because they can tell which colour it is. C.Do you think we can make a real human brain for a robot? D.The eye at the front moves with the ball to right or left. E.It's called Robot Cup football.
