新概念英語第二冊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.
課后，中國的編輯根據此句，編出如下選擇題：
7______ you read this, thousands of pictures will have been sent to us.
a． As soon as b． The moment
c． Befored． When
正確答案C
這種選擇題，實質上有閱讀理解的性質。不是真正的單項選擇題。樓主應該指出題目的出處。否則，此題從語法上講，4個選項都是正確的。因為它們都是引導時間狀語從句。A=B，D也是可以的。
Lesson 61 Trouble with the Hubble哈勃望遠鏡的困境
First listen and then answer the question.
聽錄音，然后回答以下問題。
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、《新概念英語》中的must
在《新概念英語》經典版中，must出現的頻率較高，分別出現在第一冊第43-46課、第61-66課、第77-80課、第125-132課以及第二冊第17課、第41課、第65課、第89課。
must比較常見的用法是：表義務或要求等的“必須”;表猜測的“肯定，一定”。
二、表義務或要求等
這時，must表示“必須”。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.
一般疑問句及其回答：Must he have any water after the heavy work? Yes, he must. / No, he needn't.
劃線部分提問：What must he do after the heavy work?(假如劃線部分為have some water的話)
【注意】
(一)mustn't與needn't
很多學生一說到must的否定，首先想到的一般都是mustn't。
