Ⅳ.任务型阅读
阅读下面短文,并用英语回答问题(请注意每小题的词数要求)。
Do you know the Nile River? It is the longest river in the world. It's 6,650 kilometres long. Now we will do a special experiment(实验). But nobody knows for sure who first suggested the ping-pong ball experiment along the Nile River. But some inventors(发明家) and scientists will finish it. How is the experiment done, and what does it want to show?
The experiment will end when the ping-pong ball reaches the capital city of Egypt, Cairo. At that time,a person in Cairo will reach down into the Nile,and pick up the ping-pong ball. People will follow it all along its long journey. Scientists will follow it by driving along roads. They will keep many careful records of how far the ping-pong ball goes each day. It will be an interesting experiment. But just perhaps,the experiment itself will help people realize that in some ways the earth is just a small ping-pong ball travelling through space. The earth is our home. We should love and protect it.
