It was the first time two working satellites had hit each other in orbit. The Russian satellite was an old military one that no longer worked. The American satellite belonged to a private company and was still active. At the time of the crash, both satellites were travelling at about 28,000 kilometres per hour. They were moving in opposite directions, so the collision created a huge amount of space junk—more than 2,000 pieces larger than a football, and thousands of smaller pieces. Space agencies track all large objects in space, but they didn’t notice the problem before the crash. While they were watching other objects, the two satellites were moving towards each other silently. This accident taught people how dangerous space junk can be. Even small pieces of junk can destroy a spacecraft because they are moving so fast. Today, space junk is a big problem. There are millions of pieces of junk in orbit, from old rocket parts to tiny pieces of broken satellites. Scientists are trying to find ways to clean up space and prevent future crashes. 1. When did the two satellites crash into each other? A. In 2008. B. In 2009. C. In 2010. D. In 2011. 2. Which of the following is TRUE about the two satellites? A. Both were working satellites. B. Both belonged to the same country. C. They were moving at different speeds. D. They were moving in opposite directions. 3. Why didn’t space agencies stop the crash? A. They didn’t track any objects in space. B. They were too busy with other work. C. They didn’t notice the two satellites moving towards each other. D. They thought the satellites would change direction. 4. What can we learn from the passage? A. Space junk is not dangerous at all. B. The crash created no space junk. C. Small pieces of space junk can still be dangerous. D. Scientists have already cleaned up all the space junk. 四、完形填空（共 10 小题，每小题 1 分，满分 10 分） 阅读下面短文，掌握其大意，然后从各题所给的 A、B、C、D 四个选项中选出最佳选项。 Last Saturday, I watched a TV programme about space.
