1、Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world. But ecologists can\'t be everywhere so they\'re turning to non-scientists, sometimes called citizen scientists, for help. Climate scientists are not present everywhere. Because there are so many places in the world and not enough scientists to observe all of them, they\'re asking for your help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. and send their observations to a giant database to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready for the conditions where they live. All that\'s needed to become one is a few minutes each day or each week to gather data and send it in. A group of scientists and educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group\'s first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website. "People don\'t have to be plant experts, they just have to look around and see what\'s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we\'ll be able to make an estimate of how plants and communities of plants and animals will respond as the climate changes. "What are citizen scientists asked to do?【单选题】

A.To develop a specific research interest and become professional scientists.

B.To send their research observations to a professional database.

C.To increase their knowledge about climate change.

D.To keep a record of their research observations.

正确答案:B

答案解析:根据send their observations to a giant database to be observed by professional scientists可知。

2、Storms Sink ShipsRescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21. Hundreds more are missing or feared dead. The two ferries sank in different rivers near the capital city of Dhakfi as strong winds and rain hit the South Asian country. The government has since banned all ferries and other boats from traveling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made for just 300, police said. The second ferry carried about 100 passengers. "The number of deaths is certain to rise." said an official in charge of the rescue work. "No one really knows how many people were on board the ferry or how many of them survived. Ferries in Bangladesh don\'t always keep passenger lists, making it difficult to determine the exact number of people on board. Besides the ferry accidents, at least 40 people were killed and 400 injured by lightning strikes, falling houses and trees and the sinking of small boats. Storms are common this time of year in Bangladesh, as are boating accidents. Ferry disasters take away hundreds of lives every year in a nation of 130 million people. Officials blame these river accidents on a lack of safety measures too many passengers in boats and not enough checks on weather conditions. Ferries are a common means of transport in Bangladesh. It is a country covered by about 230 rivers. Some 20,000 ferries use the nation\'s Waterways every year. And many of them are dangerously overcrowded. Since 1977, more than 3,000 people have died in some 260 boating accidents.Officials attribute boating accident to____. 【单选题】

A.strong winds.

B.bad weather conditions.

C.the blockages of waterways.

D.the lack of safety measures.

正确答案:D

答案解析:倒数第3段说到了缺乏安全措施。

3、Arctic MeltEarth\'s North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But for many years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drop in end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. And it\'s a very large 23 percent below the previous record low, which was set just 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.What may be some of the reasons for the ice melt in the Arctic? ______【单选题】

A.Unusually strong winds and clearer skies.

B.Heavy clouds and light winds.

C.Longer summers and shorter winters.

D.Thin ice and open water.

正确答案:A

答案解析:本题有一定的难度，但答案依据还是比较明显，不过跨越了两个段落，文章第五段谈到去年有强风刮过北极，第六段谈到科学家怀疑云层少了，所以答案是A。

4、The carCars are an important part of life in the United States. Without a car most people feel that they are poor. And even if a person is poor he doesn\'t feel really poor when he has a car. Henry Ford was the man who first started making cars in large numbers. He probably didn\'t know how much the car was going to affect American culture. The car made the United Stated a nation on wheels. And it helped make the United States what it is today. There are three main reasons why the car becomes so popular in the United States. First of all, the country is a huge one and Americans like to move around in it. The car provides the most comfortable and cheapest form of transportation. With a car people can go anylace without spending a lot of money. The second reason cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the country as they are in other parts of the world. Nowadays there is a good system of air-service provided by planes. But it is too expensive to be used frequently. The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don\'t like to wait for a bus, or a train or even a plane. They don\'t like to have to follow an exact schedule. A car gives them the freedom to schedule their own time. And this is the freedom that Americans want most to have. The gas shortage has caused a big problem for Americans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas. Henry Ford was the first to ____ cars in large numbers. 【单选题】

A.invent

B.sell

C.have

D.produce

正确答案:D

答案解析:依据第2段第1句“Henry Ford was the man who first started making cars in large numbers”。make:制造，等于produce。
