Q: Read the article and select the best answer. Article: It is the duty of every man to work. The life of a lazy man is of no use to himself and to others. The man who is too lazy to work is the man who is generally most ready to beg or to steal. Every boy, when he is young, should learn how to do some useful work. But it is not enough that a boy should learn some kind of work. He should put his heart and soul completely into his work, and not waste his spare time.

There is no better help to diligence than the habit of early rising, and this, just like all other good habits, is most easily formed in youth. There is an English saying, "Lost time never returns". This means that everybody must be diligent and make good use of his time. One must study hard when one is young so that one may make great progress, succeed in life and become useful to one's country. Those who are diligent will never become beggars.

Q: Read the article and select the best answer. Article: An experimental treatment that causes AIDS patients to develop a dangerously high fever has shown promise as a way of prolonging and improving the patients' life.Called the Biologic-HT System, the new treatment lets doctors extract the blood of a patient and heat it before circulating it back into the body. The heated blood causes the patient's body temperature to rise above 42 degrees Celsius. In people with AIDS, that increase in temperature kills some heat-sensitive HIV, the virus, most doctors say, causes AIDS. Heating the blood of AIDS patients has been tried before, say doctors. But during previous attempts, the treatment induced deadly chemical changes in the blood. The Biologic-HT System prevents those changes from happening, allowing the heat to kill viruses with few ill side effects. The new heat treatment cannot be considered a cure for Aids, says president of the company that makes the system. He says the treatment doesn't kill all traces of the virus. However, it kills enough virus particles to give a patient's immune system a reprieve in its deadly duel with HIV. Tests of the Biologic-HT treatment began on 36 patients earlier this year. The treatment takes about four hours, and the patient normally feels well enough to leave the hospital or clinic the following morning. So far, the patients who have had the treatment say they feel better and have developed no new opportunistic infections--disease that strike people with damaged immune systems. The patients also have experienced about a 50 percent increase in the number of T cells in their bodies. T cells are key disease-fighting cells of the immune system and the main target of HIV. Question: According to the passage, the new treatment _ . Options: A: can kill all the HIV viruses B: cannot eliminate the viruses completely C: can double the number of disease-fighting cells D: can reconstruct the patient's immune system.
A: B

Q: Read the article and select the best answer. Article: Little Mark is only 6, but he has an IQ of 200, a genius among geniuses. _ His parents must keep him intellectually simulated while making sure he is like any other little boy. Mark has been attracted by the way how the world works since he was a baby. When he was 3, Mark was reading fluently, mostly self-taught. His parents haven't been able to keep him away from books since. "I tried many times to stop him reading. We worry about his crazy fond of reading because he constantly wants to read every-thing whatever it is." A psychologist at the Centre for gifted children tested Mark and gave him an IQ of 200. The average child of Mark's age has an IQ of 100. At 200, Mark is a genius-even compared with other child geniuses. "With children like Mark you can tell that's a bright child as soon as they walk in. They just have this sort of intensity, and maybe they're not so good at communicating with people," the psychologist said. "He will never fit perfectly into a class where he's with children of his age."But Mark's mother worries about the "socially isolated" labels. "Nobody wants their child to grow up with that image. I want him to communicate with others freely, but not to be frustrated academically, so it's really hard to find a balance," she says. Helen Dudeney from the Talented and Gifted Children Association says Mark is one in a million with such a high IQ. She points out that geniuses are still rare and difficult for the public education system to handle. "The lack of coping comes because teachers aren't trained in teaching gifted children," says Dudeney. Helen believes it's also extremely important for them to be recognized and supported in their talents. Mark's parents are trying to figure out how best to help Mark. At the moment, there are few options. Mark finds first year work boring and simple, but he must learn to complete the work. His mother says, "We just want to be happy. Just to have a happy childhood and want to go to school every day." Question: What would be the best title for the passage? _ Options: A: A genius' craziness for books B: The life of the genius' parents C: The burden of being gifted D: The characteristics of Mark
A: C

Q: Read the article and select the best answer. Article: Houses fall down. Trees fall over. Large holes form in the ground. Could Alaska be sinking? That's what some villagers in Alaska have been asking themselves recently--and scientists think they know why. Warmer temperatures may be causing Alaska's frozen ground to thaw . About 85 percent of Alaska's land surface has _ . Permafrost supports the ground above it--including trees, houses, and roads. But why is the permafrost thawing? Some scientists say that human-caused pollution is leading to global warming. And most scientists agree that Alaska has been getting warmer. They say that the warmer temperature is causing permafrost to thaw in some areas. The thawing permafrost can cause problems for people, plants, and animals. "The collapsing is a problem in the villages in Alaska which are built on permafrost, and some of them may have to move to safer ground, where there is no permafrost," Weller said. The Alaskan town of Glennallen saw its old post office collapse. And, according to James Walters, a permafrost expert at the University of Northern Iowa, house-moving companies have been very busy. "Melting permafrost can also destroy trees and forests," Weller said. "When holes in the ground form, trees fall into them and die. This could turn a forest into a swamp , and animals which need the forest will have to move elsewhere." The melting could cause "severe problems." Weller says: "This could take hundreds of years, but in the end Alaska will look quite different from what it looks like now." Question: What does the word "permafrost" refers to in this passage? Options: A: It is a part of the ground that is always frozen. B: It is a part of land on which people live. C: It is a part of land on which people build houses. D: It is a part of ground with solid rocks.
A: A
