2019中考（人新）英语八下U10阅读练习及答案 一、阅读理解： A As space science develops（发展）, 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（伤害）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（有效的）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.

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.
