The machines have names like Space Warr

11、ior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back. Many teenagers like electronic games so much that they cant stop playing. They spend hours tightly holding the joystick controls and

12、 constantly pressing buttons marked “fire”. They develop pains on their fingers because of the constant pressure. They play and play that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: The muscles of the w

13、rist and arm become so inflamed and swollen(充血红肿) that they press against the bones. This condition is what doctors now call “Space Warriors Wrist”.Other strange aches and pains also are likely to affect the elbows and shoulders. Another even more alarming problem is shown by the case of a 17-year-o

14、ld girl which was recently reported in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a

15、 game called Dark Invader, she lost consciousness(晕倒) and fell to the floor.

17、-old girl given by the writer shows that the writer _.

These machines can do jobs in places that are too dangerous for human

19、s. For example, they are being developed to work in nuclear power center, deep under the oceans and in outer space. John Marrit, a psychologist(心理学家) in Williamsburg Massachusetts, helped develop the new machine. This is how they work. A machine is placed in an area far away from the person who oper

20、ates it. The person wears special hard hat with television screens and sound equipment. The screens and sound equipment let the person see and hear exactly what the machine is seeing and hearing. Mr. Marrit says this gives the person the feeling of being in the same place as the machine. The idea, h

21、e says, is being there without going there. The person uses an electronic control to make the machine move. The machine copies the persons movements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an expert can do a dangerous job while staying in the sa

22、fe place. For example, a person can direct the machine to destroy a bomb without going near the bomb himself.25. The new kind of machine being introduced in the passage is _.A. in existenceB. only an idea C. being tried outD. being researched and developed26. The machine _.A. follows the persons ord

23、er B. is controlled by a computerC. does exactly what the person does D. is controlled by a television on the persons head27. The difference between such a new machine and a robot is that _.

24、d C. a robot is controlled by man indirectly D. a robot cant be used in places too dangerous or faraway C You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be

25、seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You

26、see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight. When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no

27、light for the book to reflect, then you could not see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilomete

28、rs away, in only a little more than a second.28. The underlined word “luminous” means_. A. visible B. all colors C. giving off light D. sunlight29. _ have light of their own.A.

We are using up our natural resources too quickly, and at the same time we are polluting our environment 32_ dang

31、erous chemicals. If we continue like this, human life on earth will not survive.Everyone realizes today that if too many fish are taken from the sea, there will soon be 33_left. Yet, with modern fishing methods, more and more fish are 34_. We know that if too many trees are cut down, forests will 35_ and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.We realize 36_ if rivers are polluted with waste products from factories, we will die. However, in most countries was
