听力原文：Of all the stars the sun is the nearest to the earth. Millions of other stars are

听力原文： Of all the stars the sun is the nearest to the earth. Millions of other stars are even bigger and brighter than the sun. They look small only because they are much farther away. You can't see them in the daytime. But if you go out at night, you'll be able to see thousands of them.

The earth is one of the sun's planets, and the moon is one of the earth's planets, and men have visited it already. No man has traveled farther than the moon, but spaceships without people have reached other planets.

Many countries have sent up man-made satellites to circle the earth. With their help, people have done much research in many fields of science. Some countries have sent up man-made satellites to send and receive TV programs. This has helped the people of China and ether countries to understand each other better.

(33)

A．It is the smallest one of all the stars.

B．It is the nearest one to the earth.

C．It is the biggest one of all the stars.

D．It is the farthest one from the earth.

听力原文：Some people dream of being president of the United States, some of becoming stars

听力原文： Some people dream of being president of the United States, some of becoming stars in a Hollywood movie, and others of making millions of dollars overnight. Could a dream like that come true in real life？ Well, it did happen to Peter Johnson. Peter was an auto mechanic. One day, he walked into the Union Trust Bank in Waltermore and took ＄5,000 that did not belong to him. The guards and other employees stood back and let him stuff the bills into his shirt and pants without trying to prevent him from taking the money. No one pressed the alarm. No one pulled the gun. No one called the police. Why did they allow him to get away with it？ Well, everything was legal. Peter had won a contest promoted by a Waltermore radio station. The first prize entitled him to enter the Union Trust Bank to gather up as much money as he could lay his hands on within five minutes. Because he could not bring any large sacks or boxes into the bank, all the money had to be placed in his pockets. As the time went by, Peter ran about wildly and tried to pick up as many large bills as he could find. When his time was up, he was out of breath, but was ＄5,000 richer.

(23)

A．Mechanic.

B．Bank employee.

C．Bank guard.

D．Policeman.

Galaxies are the major' building blocks Of the universe: A galaxy is giant family of many

millions of stars, and it is held together by its own gravitational field. Most of the material universe is organized into galaxies of stars together with gas and dust.

There are three main types of galaxy: spiral, elliptical, and irregular. The Milky Way is a spiral galaxy, a flattish disc of stars with two spiral arms emerging from its central nucleus. About one-quarter of all galaxies have this shape. Spiral galaxies are well supplied with the interstellar gas in which new stars form. as the rotating spiral pattern sweeps around the galaxy it compresses gas and dust, triggering the formation of bright young stars. The elliptical galaxies have a symmetrical elliptical or spheroidal shape with no obvious structure. Most of their member stars are very old and since ellipticals are devoid of interstellar gas, no new stars are forming in them. The biggest and brightest galaxies in the universe are ellipticals with masses of about 1013 times that of the sun, these giants may frequently be sources of strong radio emission, in which case they are called radio galaxies. About two-thirds of all galaxies are elliptical. Irregular galaxies comprise about one-tenth of all galaxies and they come in many subclasses.

Measurement in space is quite different from measurement on Earth. Some terrestrial distances can be expressed as intervals of time, the time to fly from one continent to another or the time it takes to drive to work, for example. By comparison with these familiar yardsticks, the distances to the galaxies are incomprehensibly large, but they too are made more manageable by using a time calibration, in this case the distance that light travels in one year. On such a scale the nearest giant spiral galaxy, the Andromeda galaxy, is two million light years away. The most distant luminous objects seen by telescopes are probably ten thousand million light years away. Their light was already halfway here before the Earth even formed. The light from the nearby Virgo galaxy set out when reptiles still dominated the animal world.

What does the second paragraph mainly discuss？

A．The Milky Way.

B．Major categories of galaxies.

C．How elliptical galaxies are formed.

D．Differences between irregular and spiral galaxies.

DMillions of stars are travelling about in space. A few form. groups which journey togethe

r, but most of them travel alone.

And they travel through a universe so large that one star seldom comes near to another. For the most part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbor. From this it is easy to understand why a star seldom finds another anywhere neat it.

We believe, however, that some two thousand million years ago, another star wandering (漫游) through space, happened to come near our sun, Just as the sun and the moon raise tides (潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; a large tidal wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space.

These small pieces have been going round the sun ever since. They are the planets (行星).

第47题：Millions of stars are ________.

[A] following a regular path in space

[B] moving about without a fixed course

[C] seldom wandering about in the universe

[D] always travelling together

What Makes a Soccer Player Great？

Soccer is played by millions of people all over the world, but there have only been few players who were truly great. How did these players get that waywas it through training and practice,or are great players "born, not made"？ First, these players came from places that have had famous stars in the past players that a young boy can look up to and try to imitate (效仿 ). In the history of soccer, only six countries have ever won the World Cup---three from South America and three from Western Europe. There has never been a great national teamor a really great player from North America or from Asia. Second, these players have all had years of practice in the game. Alfredo Di Stefano was the son of a soccer player, as was Pele. Most players begin playing the game at the age of three or four.

Finally, many great players come from the same kind of neighbourhood (聚居区) --a poor,crowded area where a boy&39;s dream is not to be a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer. For example, Liverpool, which produced the Beatles (甲壳虫乐队) , had one of the best English soccer teams in recent years. Pele practiced in the street with a"ball" made of rags (破布). And George Best learned the tricks that made him famous by bouncing the ball offa wall in the slums (贫民窟) of Belfast.

All great players have a lot in common, but that doesn&39;t explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique quality that sets them apart from all the others.

According to the author， which of the following statements is true？查看材料

A.Great soccer players are born， not made

B.Truly great players are rare

C.Only six countries have ever had famous soccer stars

D.Soccer is the least popular sport in North America and Asia

Light Night, Dark Stars Thousands of people aroundthe globe step outside to gaze at their

Light Night, Dark Stars

Thousands of people aroundthe globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, or artificiallights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, anastronomer with the University Corporation for Atmospheric Research (UCAR) in Boulder, Colo.But when people are surrounded by city lights, he says, they're lucky to see 150 stars.

If you've ever driventoward a big city at night and seen its glow from a great distance, you've witnessed light pollution. It occurs whenlight from streetlights, office buildings, signs, and other

sources streams into space and illuminates the night sky. This haze oflight makes many stars invisible to people on Earth. Even at night, big citieslike New Yorkglow from light pollution, making stargaz-ing difficult.

Dust and particles ofpollution from factories and industries worsen the effects of lightpollution."If one city has a lot more light pollution than another,"Ward says, "that city will suffer the effectsof light pollution on a muchgreater scale. "

Hazy skies also make it farmore difficult for astronomers to do their jobs.

Cities are getting larger.Suburbs are growing in once dark, rural areas. Light from all this newdevelopment is increasingly obscuring the faint light given off by distantstars. And if scientists can't locate these objects, they can't learn moreabout them.

Light pollution doesn't onlyaffect star visibility. It can harm wildlife too. It's clear that artificiallight can attract animals,'making them go off course. There's increasingevidence, for example, that migrating birds use sunsets and sunrises to helpfind their way, says Sydney Gauthreaux Jr. , a scien- tist at Clemson Universityin South Carolina."When light occurs at night, " he says, "it has a very dis- ruptive influence." Sometimes birds fly into lighted towers, high-rises, and cables fromradio and tele- vision towers. Experts estimate that millions of birds die thisway every year.

41.When can people see 14,000 stars？

A.When they have a fairly good telescope

B.When they are in a large city

C.When the n:ght sky is clear of clouds, moonlight and artificial lights

D.When the night sky is without haze and fog

A superstar usually is someone who has become famous in sports, or films, or popular music

, someone like the famous singer Michael Jackson.

One of the most famous sports superstars in the United States was the boxer, Muhammad Ali. As a young man, he won a gold medal in the Olympics as a boxer. Then he became the heavy weight boxing champion of the world. Before long, he was known as one of the greatest boxers in sports history. Once Ali said when he was a champion he was more famous than the president of the United States or the head of any other country in the world.

The word "super" means something that is good, and of course, a star is a person who is famous. So people use "superstar" to describe the top people in sports, films or music. But like the stars in the sky, a superstar disappears as time goes by. Many people, for example, know little these days about Ali or Jackson. Superstars are loved by millions of people today, but often forgotten tomorrow.

Michael Jackson is famous for his______ but Muhammad Ali for his______.

A．films; heavy weight

B．basketball; Olympic record

C．songs; heavy weight boxing

D．voice; Olympic record

第10题

In 1961, scientists set up gigantic, sensitive apparatus to collect radio waves from the f

ar reaches of space, hoping to discover in them some mathematical pattern indicating that the waves were sent out by other intelligent beings. 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 own; so, allowing a billion years or two--or three--there would be a very good chances for life to develop, if current theories of the origin of life are correct.

But intelligent life7 Life that has reached the stage of being able to send radio waves out into space in a conscious pattern7 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 we are capable of sending radio waves into space. From this it might seem that even if there were no technical problems involved, the chance of receiving signals from another 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 odds, it seems certain that there are millions of intelligent life forms scattered through space. The only trouble is, none may be within our reach. Perhaps none never will be; perhaps the distances that separate us from our fellow inhabitants 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 one of them may come across us. What would they be like, these extraterrestrial(地球以外的) creatures？

If the radio waves had reached our planet one hundred years before, we would have______.

A．sent an immediate answer

B．sent an alarm against extraterrestrial attack

C．sent a short reply

D．sent no answer
