Q: 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. What is the direct reason for the polar bear to become endangered? A) It is that the floating ice upon which they survive melts away. B) It is that more greenhouse gases have been sent out. C) It is because of the global warming. D) It is because of no protection of their living conditions.

Q: Sub-Saharan Africa has the world's highest hunger rate. But according to a new report, African farmers also have ideas that could help the world fight hunger and poverty. Danielle Nierenberg from the Worldwatch Institute in Washington spent a year visiting twenty-five countries south of the Sahara. In Nairobi, Kenya, for example, Ms Nierenberg found women farmers growing vegetables just outside their doorsteps in the Kibera settlement. She says they are finding ways to make their lives better. The women feed their families and sell their _ They use the money to send their children to school. Last year, about 925,000,000 people worldwide did not get enough to eat. Half of all people in the world now live in and around cities. Researchers like Ms Nierenberg are looking increasingly at creative ideas to feed those who don't have enough good food to eat. She says there are a lot of lessons that people in the Western world can learn from Africa. And what they are doing can certainly be done in other developing countries. Farmers in the developing world lose between twenty and forty percent of their harvest before it ever reaches market. There are many reasons why food gets wasted. Farmers are without electricity and cold storage. They lack good seeds and fertilizer. They lack good roads. Conditions like these keep small farmers in poverty. Ms Nierenberg says more attention needs to be paid to protecting harvests. She says, "Given all that we invest in producing food in the first place, we need to devote the same amount of attention to making sure that it is not wasted." In Nigeria, village processing centers are helping farmers reduce their losses and earn more money. They centers process cassava, a root vegetable, into basic food products. In Uganda, the Worldwatch report says some schools are teaching children how to grow local kinds of crops. And in South Africa and Kenya the report praises the breeding of local kinds of livestock. These animals may produce less milk or meat than other breeds, but they can... We could learn from the new report in Para.1 that _ . A) sub-Saharan Africa has the world's highest hunger rate B) African farmers have ideas to help fighting hunger and poverty C) women farmers grow vegetables in the Kibera settlement D) women farmers grow vegetables to send their children to school.

Q: When you were looking for a reliable, honest auto mechanize, how did you find him? Before you went into that restaurant you recently tried, how did you know that it served great good? If you are like most people on the planet, you want to lower your risk of a big ugly surprise so you asked people you trust to refer to a business they trust. Marketers call this friend-to friend recognition of business "word-of -mouth advertising. When you do a treat job for your customer for a band job, people are going to talk about your business.

Q: In Jane Austin's time, unmarried girls were always closely guarded, and hardly allowed to be alone with a young man; and during the Victorian period (just the period after Jane Austin) exposure of the body in particular was thought to be most immoral, Victorian ladies wore dresses reaching down to their feet, long in the sleeve and high at the neck. Since then, ways of dressing as well as times have changed. Girls were no longer guarded, and they can do more or less what they like. And yet among all these astonishing changes, one thing has remained much the same for most people, and that is the same of becoming a mother before being married. If this does happen, there often comes a quick marriage with the responsible man. If this is impossible, the affair may bring considerable shame to the girl's parents as well as to herself. It is now quite normal for a girl, once past the age of about fifteen, to go out with a boyfriend, and although her parents will probably insist that she come home at a certain time, beyond this they depend on her or look after herself. Kisses between young men and women are now considered to be perfectly normal, but although times have changed so much, most people still believe that a woman should not become a mother before being married. From the article, we learn that _ . A) an unmarried girl must come back home for the night. B) it is good for a girl of 15 to have a boyfriend. C) the unmarried girl who has a baby needn't get married at once. D) a girl of 15 has the right to be alone with her boyfriend.
