The prefix = st1 /USgovernment has announced plans to list polar bears as a threatened species because of concerns that the ice where they live is melting. But as the BBC's Owen Clegg reports, theUSplans are also important for other reasons. It's estimated that there are no more than twenty-five thousand polar bears living in the wild, and this number could go down by a large amount as the floating ice upon which the bears survive melt away. Now, without admitting the cause of this melt, the US Fish and Wildlife Services are reviewing the bear's living conditions. That action is being taken at all, and marks an important change for the Bush administration; for the first time, it may be forced to acknowledge a link between global warming and its effect on a species. Such a conclusion by an unwilling Bush administration could force far wider changes inWashington's policy towards the environment. This review only came about after a union of environmental groups brought a legal case against the government to take action. Environmentalists, like David Doniger, believe that by calling on the protections of the Endangered Species Act, theUSgovernment may finally be forced to cut back on its sending out greenhouse gases: "It is a very important thing today to have the Bush administration notice that global warming is threatening the existence of the polar bear. Now, it's up to the administration to do something to stop the global warming that's threatening the polar bear." ( David Doniger) The United States is the world's largest emitter of greenhouse gases which are blamed for trapping heat from the sun and changing the earth's climate. Since taking office in 2001, President Bush has refused to make the link with global warming, but the bad, serious situation of the polar bear may force that position to change. Which country has been sending out the largest number of greenhouse gases according to the passage? A) China. B) Britain. C) TheUnited States. D) Not mentioned.

(Question)
In the last few years, some researchers have decided to study why kids lie ,So they made up a special team of 12 students, all under the age of 21. Each student was given 36 cards, and each card listed a topic that teens sometimes lie about to their parents, The researchers worked through the cards with the teens, learning what things the kid was lying to his parents about, and why. By the end of the interviews, the kids saw for the first time how much they were lying and how many of family's rules they had broken. It was reported that 98% of the teens had lied to their parents. Out of the 36 topics, the average teen was lying to his parents about 12 of them. The teens lied about what movie they went to, and whom they went with .They lied about how they spent their afternoons while their parents were at work, and something like that. Most parents hear their child lie and think he's too young to understand what lies are or that lying is wrong. They believe their child will stop when he gets older. Many books also advise parents to just let lies go -- they'll grow out of it. But the truth is that kids grow into it. In studies where children are observed in their natural environment, a 4-year-old child will lie once every two hours, while a 6-year-old child will lie about once every hour and a half. The topics on 36 cards are mostly between kids and _ . A) parents B) teachers C) researchers D) friends

Basketball really took a turn in the1980's as Magic Johnson and Larry Bird took the NBA to another level.Of course,basketball was already popular and had seen such stars as Jerry West and Dr.J,but the real breakthrough came in the 1980's and from there it really took off with Michael Jordan into the 90's.Basketball has even become very global now as many NBA stars competed in the Olympics and faced no competition.Today,they had better be ready because there are so many talents in other countries and the competition will be stiff. Like basketball,American football has always been a favorite of many sports fans and its popularity has grown widely.The ratings that Super Bowl Sunday brings are amazing.They have even talked about making Super Bowl Sunday a national holiday. In the year 2050,basketball and American football will have history like baseball's rich history and maybe American national sport.They have been trying for years,but it is not going to happen. So what is American's number one sport?

This passage mainly talks about A) baseball and its history B) the most popular sport in the world C) which sport is the number one in America D) whether basketball is a global sport pastime

Li Denghai, with his muddy boots and tanned face, may not look like he is one of China's famous agricultural pioneers. But the 61-year-old man from Shandong Province has made scientific breakthroughs , which made great contributions to China's food security . His main work has been in achieving the higher output of corn production. Li, who holds the world record for the highest output of summer corn, once says, "Corn has a life; it sings and dances. If you listen clearly, it can speak to you." He started his research in 1969 when he was 20 and just dropped out of a high school. He then read an article which pointed that corn output per mu in the USA was six times higher than that in China. He was shocked and set out to work on just a small piece of land _ to see if he could increase the output. He often went to the field with a flashlight late at night, if he had been away during the day. By careful nurturing he managed to double the output. Li Denghai was awarded the "China Award for Significant Contribution to the Maize Industry" in 2005, and the same year the company named after his own name came into the market on the Shenzhen Stock Exchange. Li, however, is never happier than when he is in the middle of his cornfields. "I can forget my tiredness when talking to my corns," he says. When Li Denghai began the study of corn, _ . A) he just graduated from an ordinary high school B) he was shocked that the corn output in China was so low C) he was only in his thirties D) he wasn't really fond of his work
