Ques:Article: American middle school students don't seem to care that they're worse at maths than their counterparts in China's Hong Kong and Finland. "I don't need it," my student says, "I'm going to be a basketball star." Or a car mechanic, or a singer. Middle school students' maths skills were tested by the International Organization for Economic Co-operation and Development. The United States ranked 28th out of 41 countries tested. After all, when was the last time you used algebra ? But maths isn't just about training Americans to become scientists. It has its own value. It helps you see patterns and develops your logic skills, and it teaches you to concentrate and to separate truth from falsehood. Maths helps you make wise financial decisions, so you can avoid false claims from advertisers, politicians and others. It helps you determine risk. For example, after an airplane crash, studies show that people are more likely to drive than to take a plane in spite of the fact that they are much more likely to be killed or injured while driving. Planes are not like criminals who repeat the same crime over and over. One plane is not more likely to crash just because another plane recently did. In fact, the most dangerous time to drive is probably right after a plane crash because so many people are on the road. It is not possible to really understand science and the scientific method without understanding maths. A rainbow is even more beautiful and amazing when we understand it. The precision of maths helps us think in a very special way. How do we bring the learning of maths back to life? I don't have the big answer. I try my best to help pupils find answers to some maths problems. When I can get one to say, "Wow, that's great," I feel the joy of a small victory. Question: The writer would agree that _ . Yes or no, is the answer "without maths we'll miss much in our life"?

Ans:No

Ques:Article: We often use an Internet search engine to find a website that will provide information. For example, if we want to learn something about the Pepsi Cola Company, its website provides information about the history of the company. We can also find articles in newspapers and magazines. We confirm information with second and third sources to make sure the information is correct. Sometimes we also use an encyclopedia --- a set of books containing information on almost any subject. Encyclopedias are written by experts and have been a trust --- worthy source of information for years. Now there is also a free online encyclopedia called Wikipedia, which is written by people around the world. Anyone can edit or add to an article, but this has caused problems. Last year, a former editor of the paper USA Today discovered wrong information about him on Wikipedia. Someone had written an article that falsely linked him to a political assassination . This wrong information was quickly corrected. According to a recent study by the publication Nature, Wikipedia has more mistakes, compared with Britannica --- a well-known printed encyclopedia. It found an average of four mistakes in a Wikipedia article, and three in an article of Britannica's. But Wikipedia supporters note that they are able to correct information when they find a mistake while written publications are not able to do this. Wikipedia started in 2001. The word "wiki" comes from "wiki wiki", which means "quickly" in the Hawaiian language. It is said that it is the largest single source of information in history. It is also one of the fastest growing sites on the Internet. It offers more than three million articles in more than two hundred languages. Each month, it records more than two billion page visits. Jimmy Wales, who helped start Wikipedia, says that its purpose is to provide everyone with a free encyclopedia written in their native language. You can find information on nearly every subject on Wikipedia. However, some experts warn people not to believe... Question: Compared with Britannica, Wikipedia _ . Yes or no, is the answer "is easier to edit and revise"?

Ans:Yes

Ques:Article: Twothirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to store water and provide power.In the US,there are more than 85,000 dams,disrupting large and small rivers,and in most cases transforming natural flow.The most famous of these,the Hoover Dam,constructed in the 1930s,is mainly responsible for the fact that the Colorado River no longer reaches the ocean. Dams,besides all their attractive benefits,also have negative impacts.Creating a reservoir means a large area must be flooded.Communities may lose their land,houses and culturally important sites. Environmentally,the new reservoir can be a paradise for wildlife,especially birds;however,it can cause greenhouse gas emissions and poison the water.Also,the dramatic rise and fall of water levels during dam releases is too extreme for plants and animals to cope with,resulting in dead zones around the shores of reservoirs.Fish that lay their eggs in the shallows,for example,may find a few hours later that those sites are high and dry. Downstream of a dam,the flow may be reduced so that farmers cannot irrigate their fields.Many rivers run through national borders,which may cause conflict over precious water.Disputes have been continuing between India and Pakistan,and Turkey,Syria and Iraq,for example. Dams don't just block the flow of water.They also prevent fish migrations,and dams are a barrier to sediment flows.Instead of rushing downriver,sediments get backed up against the dam wall,which causes the reservoir level to increase over time.However,sediments which are rich in nutrients have become a problem.The fertility of the entire system can be influenced,with soils lost during seasonal rains not being replaced. Perhaps the biggest problem can be seen in deltas,which are sinking into the oceans.Groundwater is being extracted to feed the city,causing the city to sink,and sediments washed away by the ocean are no longer being replaced.The result is that sea level rises in cities from Shanghai to Alexandria. Question: How can dams influence large cities like Shanghai? Yes or no, is the answer "They will lie below sea level in future."?

Ans:
No
