题目内容

　　Waves are beautiful to look at, but they can pull down ships at sea, wash away fields and buildings near the shore. The sun heats the earth, causing the air to rise and the winds to blow. The winds blow across the sea, pushing little waves into bigger and bigger ones.

　　The stronger the wind is, the bigger the waves are. The longer the wind blows, the larger the waves are. In a small pond big waves never build up. But at sea the wind can build up giant powerful waves.

　　A rule says that the eight of a wave (in metres) will usually be no more than one-tenth of a wind's speed (in kilometres). In other words, when the wind is blowing at 120 kilometres per hour, most waves will be about twelve metres. In 1933 the U. S. A Navy reported the largest measured wave in history, which rose in the Pacific Ocean to a height of thirty four metres.

(1) Waves are caused directly by ________

[　　]

A．the sun
B．winds
C．the sea
D．the air

(2) How many factors（因素）does the size of a wave depend on?

[　　]

A．Just one.
B．Two.
C．One or two
D．Three.

(3) If it is measured in metres, the wind' s speed is about ________ of the height of a wave.

[　　]

A．ten thousand times
B．one-tenth
C．ten times
D．one-thousandth

(4) According to the rule, the wind blew at ________ per hour when the largest wave rose in 1993.

[　　]

A．thirty-four metres

B．three thousand and four hundred kilometres

C．three hundred and forty kilometres

D．thirty-four kilometres

(5) Beautiful as waves are, they might be ________.

　　In summer,millions of people will head for the beach．And while the ocean can be a great place to swim and play,it may also be useful in another way．Some scientists think that waves could help make electricity．

　　“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?Or have you jumped in the water and felt lhe energy as waves crashed over you?”asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．”

　　Scientists are working on using that energy to make electricity．

　　Most waves are created when winds blow across the ocean．“The winds start out by snaking little ripples（波纹）in the water,but if they keep on blowing,those ripples get bigger and bigger and turn into waves,”Taylor said．“Waves are one of nature's ways of picking up energy and then sending it off on a journey．”

　　When waves come towards the shore,people can set up dams or other barricades to block the water and send it through a large wheel called a turbine（涡轮机）．The turbine can then power an electrical generator（发电机）．

　　The United States and a few other countries have started doing research on wave energy,and it is already being used in Scotland．

　　The resource is huge．We will never run out of wave power,besides,wave energy does not create the same pollution as other energy sources,such as oil and coal．

　　Oceans cover three quarters of the earth's surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks,however．

　　Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus,wave power would get in the way of fishing and boat traffic．

　　With more research,however,“many of these problems might be overcome,”Taylor said．“Demand for energy to power our TVs and computers,drive our cars,and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important,for traditional sources of energy like oil and gas may run out some day．”

　　In the future,when you turn on a light switch,an ocean wave could be providing the electricity!

The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent camera crew out one evening to film the sunset for him.

　　The next morning he said to the men, "Have you provided me with that sunset? "

　　"No, Sir," the men answered.

　　The director was angry. "Why not? " he asked.

　　"Well, Sir, " one of the men answered, "we are on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset."

　　"But I want a sunset!" the director shouted. "Go to the airport, take the next flight to the west coast, and get one. "

　　But then a young secretary had an idea. "Why don't you photograph a sunrise, " she suggested, "and then play it backwards? Then it'll look like a sunset."

　　"That's a very good idea! " the director said. Then he turned to the camera crew and said, "Tomorrow morning I want you to get me a beautiful sunrise over the sea. "

　　The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay（海湾）. Then at nine o'clock they took it to the director. "Here it is, Sir, " they said, and give it to him. He was very pleased.

　　They all went into the studio（摄影棚）. "All right, " the director explained, "now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the 'sunset' behind them. "

　　The "sunset" began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.

　　The birds in the file were flying backwards, and the waves on the sea were going away from the beach.

One evening, the director sent his camera crew out____.

　　A. to watch a beautiful sunset  B. to find an actor and an actress

　　In 1961, scientist set up gigantic, sensitive instruments to collect radio waves from the far reaches of space, hoping to discover in them some mathematical pattern indicating that the waves were sent out by other intelligent beings. The first attempt failed, but someday the experiment may succeed.

　　What reason is there to think that we may actually detect intelligent life in outer space？To begin with, modern theories of the development of stars suggest that almost every star has some sort of family of planets. So any star like our own sun （and there are billions of such stars in the universe） is likely to have a planet situated at such a distance that it would receive about the same amount of radiation as the earth.

　　Furthermore, such a planet would probably have the same general composition as our planet; so, allowing a billion years or two or three, there would be a very good chance for life to develop, if current theories of the origin of life are correct.

　　But intelligent life？Life that has reached the stage of being able to send radio waves out into space in a deliberate pattern？Our own planet may have been in existence for five billion years and may have had life on it for two billion, but it is only in the last fifty years that intelligent life capable of sending radio waves into space has lived on earth. From this it might seem that even if there were no technical problems involved, the chance of receiving signals from any particular earth-type planet would be extremely small.

　　This does not mean that intelligent life at our level does not exist somewhere. There are such an unimaginable number of stars that, even at such miserable possibility, it seems certain that there are millions of intelligent life forms scattered through space. The only trouble is, none may be within easy distance of us. Perhaps none ever will be; perhaps the distances that separate us from our fellow “creatures” of this universe will forever remain too great to be conquered. And yet it is conceivable that someday we may come across one of them or, frighteningly, one of them may come across us. What would they be like, these outside-the-earth creatures？

1.What point is the author making by stating that almost every star has some sort of family of planets？

　　A. Sooner or later intelligent beings will be found on one of the stars.

　　B. There must be one or two of the planets on which there are no intelligent beings.

　　C. There are sufficient planets for there to be one that enjoys the same conditions as the earth does.

　　D. One or two billion years later intelligent beings will generate on those planets.

2.What is the main topic of the passage？

　　A. Some probable intelligent life forms on other planets.

　　B. Various stages undergone by the intelligent life on other planets.

　　C. Grounds for probable existence of intelligent life on other planets.

　　D. The possibility of intelligent life existing on our planet.

3.Which of the following can be inferred from the passage？

A. An encounter is probable between people from the earth and intelligent beings from another planet.

B. Though the first attempt failed, scientists did discover the radio waves sent out by other intelligent beings.

C. Other intelligent beings were able to send our radio waves into space well before the last fifty years.

D. It is certain that there are millions of intelligent beings scattered in space but only too far away.

4.According to the author, what is the difference between “we may come across one of them” and “one of them may come across us”？

A. The earth would be dangerously disadvantaged if it is sought after by possibly much more developed creatures.

B. It would prove that there are too many outside-the-earth creatures if “one of them comes across us”.

C. The history of the development of the earth would be proved to be shorter than that of “them” if “they” come across us.

D. it would prove that the distance in between is not so great as we think if “we come across one of them” someday.
