Her rare condition has just eight hundred documented sufferers throughout the world, and causes diseased pieces of the lungs to filter oxygen through extra layers of cells, making it hard or almost impossible to breathe. For Alida and her parents, it meant that even a walk in the park was very difficult because oxygen equipment was too heavy for the youngster to be able to carry herself. As parents, they wanted to do something to help their daughter survive despite having a tube following her all the time. _ found out about "service dogs" from a TV program and realized an animal trained to help the blind could be trained to help Alida.

Snow-melting Agent A heavy snow can kill pests and this means a good harvest next year.This will bring as well as trouble to urbanites. On Nov.16,2003,a cold air current brought a heavy snow to Beijing.To prevent traffic jams,related government departments mobilized people to clear off snow on streets. One of the most effective ways to clear off snow on roads is to scatter snow-melting agent on the roads.The major component of the snow-melting agent is salt.The snow-melting agent can make snow stop from freezing,make it easier to clear off the road,and allow traffic to flow smoothly.But it also brings about some hidden dangers.In the spring of 2003,over 300 000 trees in Beijing urban districts died.After analyzing soil around these trees,experts discovered that the salt content of these soils was 392 times higher than normal.Where did the excessive salt come from?After investigating,forestry experts found that when clearing snow in the winter,people usually heap snow containing snow-melting agent at trees' roots,and that when the snow melts,this agent penetrates the soil and increases its salt content.The snow-melting agent indirectly killed the trees. Statistics show that during a heavy snow in 2002,over 1000 tons of snow-melting agent was scatterred on streets in Beijing.Snow water containing a large amount of snow-melting agent got into the soil through sewers. In addition,salt in the snow-melting agent can expedite the corrosion of steel bars in concrete buildings and cause the concrete to crack and peel,shortening the life of roads. Scientists and government officials are required to solve traffic problems caused by heavy snows as soon as possible and at the same time try to reduce the negative effects of the snow-melting agent.This is a difficult problem placed before them.Related authorities have framed some local criteria to regulate the production and use of snow-melting agents. Now,more harmless snow-melting agents are being developed.Now that even snow-melting agents that meet today's criteria must... This text most probably appears in _ . A) a newspaper B) a magazine on latest findings C) a book on salt D) a magazine on environmental protection

Q: Barack Obama has never been shy about comparing himself with Abraham Lincoln. He did so when he announced his presidential election in Illinois, where both he and Lincoln served in the legislature . "The life of a tall, thin, self-made Springfield lawyer tells us that a different future is possible." Obama said. "He tells us that there is power in words and that there is power in hope." Such comparisons have continued on big and small occasions, but the most important similarity, in Obama's mind, is how he plans to govern if elected. Obama says he admires Doris Kearns Goodwin' s wonderful Lincoln biography, Team of Rivals. "He talks about it all the time." says a top assistant. "He is particularly interested in the idea that Lincoln successfully won the hearts of many people who had run against him for President, some of them even disagree with him firmly." "The lesson is that you shouldn't let your hatred get in the way of hiring ly the best people." says Obama. "I think American people are practical and so I have an interest in casting a wide net, seeking out people with a wide range of expert knowledge, including Republicans, for the highest positions in the government." "I don't want to have people who just agree with me." He says. "I want people who are continually pushing me forward and I'd be very interested in having those sorts of Republicans in my government, especially people who can speed up a responsible and logical conclusion to the Iraq war." The author wrote the passage to _ . A) compare Obama and Lincoln B) help Obama to win more support C) tell us something about Obama D) announce Obama's political ideas

*Question*
Dr Wiseman started "the laugh lab" project in September 2001. It is the largest study of humour. Participants are invited to log on to the laugh lab website, give a few personal details, tell their favourite jokes and judge the jokes told by other people. The project will last for a year, and the organizers hope to finally discover the world's funniest joke. But there is also a serious purpose. The researches want to know what people from different nations and cultures find funny. And they want to find out the differences between the male and female sense of humour. The idea is that if we want to understand each other, we have to find out what makes us laugh. This is a subject that has long attracted psychologists and philosophers. Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves. By December 2001 over 10, 000 jokes had been submitted. This gave the scientists enough evidence to make early conclusions. It seems that men and women do have different senses of humour, for instance. "Our findings show the major differences in the ways in which males and females use humour, " said Dr. Wiseman. "Males use humour to appear superior to others, while women are more skilled in languages and prefer word play. " Researchers also found that there really is such a thing as a national sense of humour. The British enjoy what is usually called "toilet humour". But the French like their jokes short and sharp: "You're a high priced lawyer. Will you answer two questions for $500?" "Yes. What's the second question?" The Germans are famous for not having a sense of humour. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality. Perhaps that proves the point. Is this joke funny? I don't know, but let's say yes, just to be safe. Dr Wiseman and his workmates also submitted jokes created by... We can infer from the passage that _ . A) most of the people all over the world are completely honest B) psychologists and philosophers take interest in the "laugh lab" project C) ordinary people are not interested in "the laugh lab" project at all D) people tell the truth about themselves only when they laugh
