| 第2、3、4、5、6、7、8题：The Milky Way(银河) contains billions of Earth-sized planets that could support life.That's the finding of new study.It draws on data that came from NASA's top planet-hunting telescope. A mechanical failure recently put that Kepter space telescope out of service.Kepler had played a big role in creating a census of planets orbiting some 170,000 stars. Its date have been helping astronomers predict how common planets are in our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth. The authors of a study published in The Proceedings of the National Academy of Sciences conclude that between 14 and 30 out of every 100 stars with a mass and temperature similar to the Sun may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth's but no more than twice that big.The planet also would have to orbit in a stor's habitable zone. That's where the surface temperature would allow any water to exist as liquid. The new estimate of how many plantes might fit these conditions comes from studying more that 42,000 stars and identifying suitable worlds orbiting them.The scientists used those numbers to extrapolate(推算) to the rest of the stars that the telescope could not see. The estimate is rough，the authors admit. If applied to the solar system，it would define as habitable a zone starting as close ot the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike(although either might have been in the distant pase). Using tighter limits the researchers estimate the between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to complete a yearly orbit. Four out of every 100 sunlike stars doesn't sound like a big number. It would mean however that the Milky Way could host more than a billion Earth-sized planets with a chance for life. 16. The Kepler space telescpe has been in service for 15 years A Right B Wrong C Not mentioned17.The main task of the Kepler space telescope is to find out planets with similar conditions to Earth's. A Right B Wrong C Not mentioned18.The planet that could support life might be a little bit smaller than Earth. A Right B Wrong C Not mentioned19.The Earth is a planet orbiting in the Sun's habitable zone. A Right B Wrong C Not mentioned20.The new finding is based on a thorough study of 170,000 stars on the Milky Way. A Right B Wrong C Not mentioned21.The estimate of the number of planets that could support life is not very accurate. A Right B Wrong C Not mentioned22.This is the first research finding about the planets with a chance for life. A Right B Wrong C Not mentioned |

| 第9、10、11、12、13题：The Day a Language Died When Carios Westez died at the age of 76, a language died, too. Westez, more commonly known as Red Thunder Cloud, was the last speaker of the Native American language Catawba. Anyone who wants to hear the songs of the Catawba can contact the Smithsonian Institution in Washington, D.C., where, back in the 1940s, Red Thunder Cloud recorded a series of songs for future generations.________ (46) They are all that is left of the Catawba language. The language that people used to speak is gone forever. We are all aware of the danger that modern industry can cause the world’s ecology(生态).However, few people are aware of the impact widely spoken languages have on other languages and ways of life. English has spread all over the world. Chinese, Spanish, Russian, and Hindi have become powerful languages as well. As these languages become more powerful, their use as tools of business and culture increases. As well,_________ (47) When this happens, hundreds of languages that are spoken by only a few die out. Scholars believe there are around 6,000 languages around the world, but more than half of them could die out within the next 100 years. There are many examples, Araki is a native language of the island of Vanuatu, located in the Pacific Ocean. It is spoken by only a few older adults，so like Catawba，Araki will soon disappear. Many languages of ethiopia will have the same fate because each one has only a few speakers. _________ (48) In the Americas, 100 languages, each of which has fewer than 300 speakers, are dying out. Red Thunder Cloud was one of the first to recognize the danger of language death and to try to do something about it. He was not actually born into the Catawba tribe, and the language was not his mother tongue._________ (49). The songs he sang for the Smithsonian Institution helped to make Native American music popular. Now he is gone, and the language is dead. What does it mean for the rest of us when a language disappears? When a plant insect or animal species dies, it is easy to understand what has been lost and to for the balance of the natural word. However, language is only a product of the mind. To be the last remaining speaker of a language，like Red Thunder，must be a peculiarly lonely destiny, almost as strange and terrible as being the last surviving member of a dying species.________ (50) A .As these languages become more powerful, their use as tools of business and culture increase. B .However，he was a frequent visitor to the Catawba reservation in South Carcinoma where he learned the language. C .Papus New Guines is an extremely rich source of different language，but more than 100 of them are in danger of extinction(灭绝). D .For the rest of us, when a language dies, we lose the possibility of a unique way of seeing and describing the world. E .Some people might want to learn some of these songs by hearts. F .These languages don’t have many native speakers. |

| 第14、15、16、17、18、19、20题：E1 Nino While some forecasting methods had limited success predicting the 1997 E1 Nino a few months in advance, the Columbia University researchers say their method can predict large E1 Nino events up to two years in advance. That would be good news for governments, farmers and others seeking to plan for the droughts and heavy rainfall that E1 Nino can produce in various parts of the world. Using a computer the researchers matched sea-surface temperatures to later E1 Nino occurrences between 1980 and 2000 and were then able to anticipate E1 Nino events dating back to 1857, using prior sea-surface temperatures. The results were reported in the latest issue of the journal Nature. The researchers say their method is not perfect, but Bryan C. Weare, a meteorologist at the University of California, Davis, who was not involved in the work, said it "suggests E1 Nino is indeed predictable." "This will probably convince others to search around more for even better methods." said Weare. He added that the new method "makes it possible to predict E1 Nino at long lead times." Other models also use sea-surface temperatures, but they have not looked as far back because they need other data, which is only available for recent decades, Weare said. The ability to predict the warming and cooling of the Pacific is of immense importance. The 1997 E1 Nino, for example, caused an estimated $20 billion in damage worldwide, offset by beneficial effects in other areas, said David Anderson, of the European Centre for Medium. Range Weather Forecasts in Reading England. The 1877 E1 Nino, meanwhile, coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China prompting the development of seasonal forecasting, Anderson said. When E1 Nino hit in 1991 and 1997, 200 million people were affected by flooding in China alone, according to a 2002 United Nations report. While predicting smaller E1 Nino events remains tricky, the ability to predict larger ones should be increased to at least a year if the new method is confirmed. E1 Nino tends to develop between April and June and reaches its peak between December and February. The warming tends to last between 9 and 12 months and occurs every two to seven years. The new forecasting method does not predict any major E1 Nino events in the next two years, although a weak warming toward the end of this year is possible. The method used by the Columbia University researchers can predict E1 Nino a few months in advance. A．Right B．Wrong C．Not mentioned 17、 The Columbia University researchers studied the relationship between the past E1 Nino occurrences and sea-surface temperatures. A．Right B．Wrong C．Not mentioned 18、 The Columbia University researchers are the first to use sea-surface temperatures to match the past E1 Nino occurrences. A．Right B．Wrong C．Not mentioned 19、 Weare's contribution in predicting E1 Nino, was highly praised by other meteorologists, A．Right B．Wrong C．Not mentioned 20、 According to a Chinese report, the flooding in China caused by E1 Nino in 1991 and 1997 affected 200 million Chinese people. A．Right B．Wrong C．Not mentioned 21、 It takes about eight months for E1 Nino to reach its peak. A．Right B．Wrong C．Not mentioned 22、 A special institute has been set up in America to study E1 Nino. A．Right B．Wrong C．Not mentioned |
