The warning is: The sun’s summertime rays are more dangerous than once thought.A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone (臭氧层) in the atmosphere，which protects humans from harmful levels of ultraviolet（紫外线）radiation，will be thinner over the United States this summer. The thinner layer allows more ultraviolet rays from the sun to reach Earth. The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.Scientists first became concerned about the ozone layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter. The hole was caused by chemicals used in refrigerators and airconditioners. When these chemicals are sent out into the atmosphere，they produce gases that destroy the ozone.Concern about the protective ozone layer rose more recently when data(数据) from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica. Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.Although many countries have already begun stopping the use of ozone destroying chemicals，the new findings are expected to advance the timetable for a total ban(禁止) of the chemicals.1. The scientists have observed the ozone layer_____.A. since 1980B. since last winterC for about 20 years D. for about one year2. The ozone layer in the atmosphere can _____.A. do a lot of good to human beings in many ways.B. protect humans from diseases caused by bad weather.C. do a lot of harm to human beings in the summer-time.D. protect humans from harmful levels of ultraviolet radiation.3. Scientists first found that there was a hole in the ozone layer_____.A. above Arctic during the winter in the mid-1980sB. above Antarctica during the winter in the mid-1980sC. over somewhere in the north of the equator in 1980D. over the U.S.A in the summertime in the mid-1980s4. The damage to the ozone layer was caused by_____.A. the changeable weatherB. ozone-destroying chemicalsC. chemicals from refrigeratorsD. chemicals from air conditionersBEarly in the morning of June 29，1991，Carrie and Morgenstern were watching the field. Although they could see nothing through the thick fog，they kept their camera running.By 6 a.m. the fog began to lift. A remarkable pair of circles had been flattened. Stalks (主茎) were bent but not broken. Outside the circles the wheat was untouched. Muddy though the field was，there were no footprints or other marks. The circles seemed to have come from nowhere. “ I can’t explain it at all ，” Mike Carrier said to himself with his eyes wide open.Carrier is not alone since the early 1980s，more than 2019 circles have app eared in farmer’s fields. Most circles form at night between May and August.Some believe the circles are caused by deer or some other animals. Others think of UFOs. “The circles are messages given by those who come from outer space，” says Michael Green. “Perhaps they are trying to get in touch with us.”Pat Delgado has done research on crop circles since 1981. He believes that they are caused by “ some form of earth energy.”Most scientists think that there’s no scientific basis to back up Green’s or Delgado’s theories. Some of them say，“We think they’re nothing but hoax(骗局).”In September 1991，Doug Bower and Dave Chorley told newsmen that since 1979 they had made circles throughout southern England to fool people who believed in UFOs.Since the early 1980s，Dr. Terence Meaden has visited more than1000 circles. Now he thinks he may have the answer. He believes true crop circles are made by vortex(旋风) which can flatten the crop in circular patterns.Now crop circles are still found in southern England each summer. Are they really the traces of UFOs?5. On the morning of June 29，1991，Carrier and Morgensern hoped to________.A. record the important thingB. draw a conclusionC. find a secret of natureD. see something funny6. When he saw the crop circle，Mike Carrie was________.A. satisfiedB. frightenedC. surprised D interested7. Most scientists consider that theories of Green and Delgado are_________.A meaningful B. reasonableC instructive D. against the laws of science8. According to the article we may know that all the crop circles______.A. are made by those who come from outer spaceB. are nothing but hoaxesC. are not hoaxes D can be explained by scientistsCThe journey to the moon had been the first step toward future exploration(探险) in space. The distance between the Moon and Earth is very short indeed when compared with the distances between Earth and the other planets. Mars，the nearest planet to Earth is millions of miles away. Traveling to the planets will be man’s next aim. Such travels will be more challenging than the trip to the moon and certainly more adventurous.Recently，two American spaceships，Vikings 1 and 2，landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither confirmed(确认) nor ruled out. Russians have discovered that the surface of Venus(金星) is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense(稠) and the pressure is nearly a hundred times greater than that of the Earth’s atmosphere.Scientists believe man may find planets which have the same conditions as those we have on Earth ，but man should realize Earth will be his only home for a long time and begin to love and care for it.9. According to the passage，traveling to the planets will be ________.A. much easier and even more interestingB. far more exciting and dangerousC. man’s final aimD. man’s first step10. Which of the following is Not true?A. Mars is nearer to the earth than the moon.B. The moon is much nearer to the earth than Mars.C. Of all the planets，Mars is the nearest to the earth.D. All the planets are much farther to the earth.11. From the passage，we can guess_____.A. there is life on MarsB. there is no life on MarsC. the atmosphere of Mars is not so dense as that of VenusD. scientists will have little hope to find the answers12. Man can live on under the conditions of _______.A much too hot surface B. the same pressure as we get on earthC. normal atmosphere as we have on earthD. both B and CDUnless we spend money to spot and prevent asteroids(小行星) now，one might crash into Earth and destroy life as we know it ，say some scientists.Asteroids are bigger versions of the meteoroids(流星) that race across the night sky. Most orbit the sun far from Earth and don’t threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth.Buy $ 50 million worth of new telescopes right now，Then spend $ 10 million a year for the next 25 yearsto locate most of the space rocks. By the time we spot a fatal one，the scientists say ，we’ll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear we apons. But the cost wouldn’t be cheap.Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is；2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500 000 years. Sounds pretty rare-but if one did fall，it would be the end of the world. “ If we don’t take care of these big asteroids，they’ll take care of us，” says one scientist. “ It’s that simple.”The cure，though ，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，”said a New York Times article.13. What does the passage say about asteroids and meteoroids? _________.A. They are heavenly bodies different in compositionB. They are heavenly bodies similar in natureC. These are more asteroids than meteoroidsD. Asteroids are more mysterious than meteoroids14. What do scientists say about the collision of an asteroid with Earth? _______.A It is unlikely but the danger existsB. Such a collision might occur once every 25 yearsC. Collision of smaller asteroids with Earth occur more often than expectedD. It’s still too early to say whether such a collision might occur15. What do people think of the suggestion of using nuclear weapons to alter the course of asteroids? _______.A. It sounds practical but it may not solve the problemB. It may create more problems than it might solveC. It is a waste of money because a collision of asteroids with Earth is very unlikelyD.
