Houston, Texas (June 8. 2002)–in 2004, the National Aeronautics and Space Administration (NASA) will send two robots to separate places of Mars to seek out past or present signs of water. It is an exciting idea to send two robots driving over very different places of Mars at the same time, to be able to see what is on the other side of the hill.
Last month, NASA announced it was sending one robot to Mars, but after two weeks, it decided there was enough money for two. The robots will be sent up within two weeks of each other in May and June of 2003 from Kennedy Space Center. If all goes well, the two spacecraft will touch down on Mars, after a seven-and –a-half-month space flight, on January 2 and 20, 2004.
The robots, each weighing 150 kilograms, can cover 100 meters per day. They are designed to be able to examine the mineral content of the soil, and their special camera will take pictures of the lands and hills. Although they will be under control from the earth, the robots are able to move more freely compared to those sent up before them.
The actual landing points have not been determined yet, but the scientists say it will be in areas where they hope to find water.
49.According to the news report, scientists plan to send robots up to Mars to _____.
A.find out whether there is water on Mars B.see if robots can find minerals there
C.test how fast robots can drive there D.prove that robots can work on Mars
50.How long in between will the two robots be sent to Mars?
A.1 year B. 7.5 months C. 2 months D. 2 weeks
51. One of the important jobs for the robots on Mars is to _______.
A.study the soil B. walk everywhere
C.test the new camera D. find a suitable landing point
52. We can infer from the last sentence that scientists ________.
A. have changed the landing points many times B. hope to land the robots on the surface of water
C. are still working on the plan D. know where they can find water |

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. |
Los Angeles June 14, 2006 – Hollywood actress Daryl Hannah was arrested yesterday after spending two weeks sitting in a walnut tree on an urban farm a few kilometers from downtown Los Angeles. She was one of 40 people, including celebrities from the music and movie world, who were protesting at the proposed destruction of the 14 – acre farm. Police officers cut away branches from the tree and used a fire engine to reach Ms Hannah and her co – protester, environmentalist John Quigley. The two of them raised their fists in defiance（反抗）as they were removed.
Protesters, some of whom had chained themselves to concrete –filled barrels（桶），said that it was essential to keep the farm operating, as it provided food for hundreds of poor families in the area. About 350 people grow produce and flowers on the farm, which has been there for more than a decade and is situated in an inner –city area surrounded by warehouses and railroad tracks. However, the local authority recently approved plans for the area to be cleared and redeveloped for the construction of a huge new warehouse.
Ms Hannah, 45, star of films such as Splash and Kill Bill was not thrilled about being arrested. “But I felt it was important to show my support for the people,” she said. “This farm should be a model for sustainable (可持续的) urban agriculture. It needs to be replicated, not eradicated.”
The record length for a tree protest is held by a woman called Julia Hill, who remained on top of a 30-metre-high redwood tree in Northern California for 738 days from December 1997 to December 1999. She was successful in saving the tree and those around it from destruction. Ms Hill was also at the Los Angeles urban farm project this week, but her presence failed to stop the inevitable (不可避免的). No sooner had the protesters been removed than earth-moving machines moved in and began to clear the land.

In front of 60,000 fans, the former Olympic and world champion, Liu Xiang got his third National Games gold medal in the final of the men’s 110 meters hurdles at the Olympic Sports Center in Ji Nan, Shandong province．
Before winning this game, Liu joined in the Shanghai Golden Grand Prix meet(上海国际田径黄金大奖赛) in September, 2009 and won the second place in men’s 110 meters hurdles with a very slight loss to his solid rival–American athlete, Terrence Trammell．That was the first time that he had shown up on the track and in public after his 13 month’s lay–off．So, this game on October 25, in 11th Chinese National Games was very critical for him to handle．After crossing the finishing line, Liu said, “The most important thing was to finish the race safely and smoothly．The result is not very good but the effort was not bad．”
With the final result of 13.34 seconds, Liu became the first Chinese hurdler to win a National Games title three times．“I’m feeling very good now,” Liu said．“I started to compete at the National Games at the age of 18 and now I’m 26．I hope I can run at the Games again in four years’ time because, for all Chinese athletes, is a dream and it is also my starting point．I would just like to thank all the people who have supported me and all the spectators who cheered for me here．”
It is hard for most of Liu’s fans to forget the heartbroken moment at Bird’s Nest last year at the Beijing Olympics because of the foot injury．Thirteen months later, however, the strong-minded man thrilled the home crowd with the strong comeback and would gain another take–off in his career．“I never thought of coming back when I got injured and I felt my future was in doubt,”Liu said, “But now I have seen there is still a future．”
