Question

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（輻射） 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（損壞）.
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.

小題1:A
小題1:A
小題1:C

【主旨大意】文章介紹了宇航員們在太空當中也會面臨著許多危險，其中主要是輻射和太空垃圾的威脅；輻射對宇航員們的傷害可能會在他們的第二代甚至第三代身上表現出來；太空垃圾中有一些是人造垃圾。太空垃圾對人們探測宇宙有很大的。
小題1:B 推理判斷題  由第三段中的句子“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.”可推斷出選項B是正確答案；
小題1:D細節理解題  根據第二段的句子“Scientists have found out that the radiation（輻射） is the greatest danger to spacemen in space. ”可知道輻射是有害的，故選D；
小題1:A詞意猜測題  根據下文中的small piece等可以看出該詞意為“碎片”，故答案選A；
小題1:A總結歸納題  文章中共提到了兩種太空威脅：一種是輻射；另一種是太空垃圾，故正確答案選A。
小題1:C 推理判斷題 根據文中第一段中的句子“ The harm of the radiation won’t be found until their children even grandchildren are born.”可得到正確答案為C。
