新概念英语第二册Lesson 61 Trouble with the Hubble
最后一句：
By the time you read this, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures.
课后，中国的编辑根据此句，编出如下选择题：
7______ you read this, thousands of pictures will have been sent to us.
a． As soon as b． The moment
c． Befored． When
正确答案C
这种选择题，实质上有阅读理解的性质。不是真正的单项选择题。楼主应该指出题目的出处。否则，此题从语法上讲，4个选项都是正确的。因为它们都是引导时间状语从句。A=B，D也是可以的。
Lesson 61 Trouble with the Hubble哈勃望远镜的困境
First listen and then answer the question.
听录音，然后回答以下问题。
What is the special importance of a telescope in space?
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.

一、《新概念英语》中的must
在《新概念英语》经典版中，must出现的频率较高，分别出现在第一册第43-46课、第61-66课、第77-80课、第125-132课以及第二册第17课、第41课、第65课、第89课。
must比较常见的用法是：表义务或要求等的“必须”;表猜测的“肯定，一定”。
二、表义务或要求等
这时，must表示“必须”。如：
肯定句：He must have some water after the heavy work.
否定句：He needn't have any water after the heavy work.
一般疑问句及其回答：Must he have any water after the heavy work? Yes, he must. / No, he needn't.
划线部分提问：What must he do after the heavy work?(假如划线部分为have some water的话)
【注意】
(一)mustn't与needn't
很多学生一说到must的否定，首先想到的一般都是mustn't。
