Lesson 61 Trouble with the Hubble

The Hubble telescope was launched into space by NASA on April 20,1990 at a cost of over a billion dollars. Right from the start there was trouble with the Hubble. The pictures it sent us were very disappointing because its main mirror was faulty! NASA is now going to put the telescope right, so it will soon be sending up four astronauts to repair it. The shuttle Endeavour will be taking the astronauts to the Hubble. A robot-arm from the Endeavour will grab the telescope and hold it while the astronauts make the necessary repairs. Of course, the Hubble is above the earth's atmosphere, so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen. The Hubble will tell us a great deal about the age and size of the universe. By the time you read this, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures.

哈勃望远镜于1990年4月20日由国家航空航天局发射升空，耗资10多亿美元。从最开始哈勃望远镜就有问题。它传送给我们的图像很令人失望，因为它的主要镜子有误差。国家航天局准备纠正这一错误，为此将把4名宇航员送入太空修复望远镜。“奋进”号航天飞机将把宇航员送上哈勃。当宇航员进行必要的修复工作时，“奋进”号上的一只机器手将抓住望远镜并托住它。当然，哈勃位于地球的大气层之外，因此，它很快就会给我们传送我们所见到过的、有关行星和远距离星系的最清晰的照片。哈勃将告诉我们有关宇宙的年龄和大小的许多事情。等到你读到这篇文章时，敏锐的哈勃望远镜已经为我们送来了成千上万张精彩的照片。

Exercise

1. They __________ for 20 years by next year.

A. will have been married    B. will be married

C. have been married         D. have married

2. By the end of this month he __________ for ten years.

A. will has lived   B. will have been living   C. will live   D. have lived

解析：1.有时间标志词for twenty years还有时间截止点by next year，因此使用将来完成时，瞬间动词不能持续一段时间，因此使用表示状态的married，故get married换成have been married。答案：A。

2.有时间标志词for ten years还有时间截止点by the end of next month，因此使用将来完成时,并且动作未完成，正在继续，所以使用进行时时态。答案：B。
