As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.

Scientists have found out that the radiation(辐射)is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health. The harm of the radiation won’t be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far.

Space rubbish is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage（损坏）.

Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may become possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.

A recently study found people’s lives are made shorter in North China. It is showed the life expectancy(平均寿命) had been cut down by 5.5 years there. Researchers think that the heavy air pollution in China should be to blame(承担责任). It’s really the truth. Our government has already done something. However, it doesn’t seem to work so well.
“Air pollution in China is doing harm to people’s health. The harm is much more serious than we can imagine,” said Chen Yuyu of Beijing University, one of researchers of this study.
Dirty air brings serious problems in North China. In January this year, the air pollution was worse than that in other places. That was caused by rising temperature and waste gas(废气) from coal heating.
Chinese government should strongly fight against air pollution. They should think of more proper ways to deal with the problem. People should be encouraged to take buses, ride bicycles or walk, instead of driving cars. The factories that pollute heavily should be closed.
“We need to improve our environment, although it might be expensive. Protecting our environment means protecting ourselves,” Li Hongbin, another researcher of the study said.

A great number of people have to s???? at home for fear of the poisonous(有毒的) air caused by the smog.

People have realized(意识到) the great harm caused by the smog and the importance of

“I had a Welsh speaking test. I'd had to memorize a paragraph in front of the whole class. I just couldn’t do it,” says 13-year-old Mary. “I pretended to be ill.” But Mary did not enjoy her day off. “I watched TV all day — it was boring. I wished I had gone to school.”
Mary’s story is not unusual in Britain. According to the latest government figures, pupil absences are rising, despite schools taking a hard line on truancy (逃学)．
Philippa James, a PhD researcher at Cardiff University’s school of social sciences, thinks she knows why: “The more schools improve methods of detection（检查）, the more children work out better methods of deception.” Teenagers told her it was now harder to skip a single lesson, so they’d miss whole days to avoid being caught.
For several years, James has researched student truancy of 60 teenagers, aged 13 and 14, including Mary, to see how the teenagers truant, for how long, and why.
Through online conversations and face-to-face interviews, she discovered that most truancy was “a response to factors within the school”. Truants are not necessarily less advanced or less intelligent. They complained of teachers who failed to engage them, and of “boring” lessons. “Many truants really enjoy school and believe in education, but drop out when aspects of it were ineffective.” James says.
The views of students like Adam, who believes that skipping lessons has little impact on his schooling, were common. “I only take-off for a lesson, or a couple of days. It doesn’t affect my education,” he told James.
James’ study concludes that schools need to address the question of why pupils want to leave in the first place. “Pupils need help from the start.” she says. “It’s a two-way process – schools must be responsive. We need to look at the reasons for truancy rather than the number, so that instead of walking away from school, students have the skills and chances to talk through problems and make a change.”
【小题1】What is one of the reasons for school truancy according to James’ study?
