Answer 1

【答案】

1.It is important?

2.ought to

3.didn’t have to

4.unless… rains

【解析】

试题分析：

1.句意：早睡是对年轻人很重要的。这里是it is+形容词+for sb to do ，it是形式主语，真正的主语是to go to sleep early ，故用It is important。?

2.句意：你应该多读英语书。这里should= ought to “应该”，故用ought to。

3.句意：他不得不熬夜因为他没有背下来新概念英语。因为谓语动词是had to，变否定句的时候应该用助动词didn’t 来帮助构成，故用didn’t have to。

4.句意：如果明天不下雨，我们将去登云台山。这里if …not = unless ；unless引导的是条件从句不能用将来时而用一般现在时，故用unless… rains。
