1.If it ______ tomorrow, we’ll go roller-skating.

A. isn’t rain B. won’t rain C. doesn’t rain D. doesn’t fine

1.【答案】C。解析：考查时间状语从句中主将从现的用法。句意：如果明天不下雨，我们将去滑旱冰。主句用一般将来时，从句往往用一般现在时。又因为实义动词的否定在前面加 doesn’t，don’t，或didn’t, it是第三人称单数，否定用doesn’t，故选C。

2.______ not for the support of the teachers, the student could not overcome her difficulty.

A.It were B.Were it C. It was D.Was it

2.【答案】B。解析：考查虚拟语气省略if的倒装形式。句意：如果不是老师们的支持，这个学生不可能克服困难。 含有were…; should…; had…的虚拟条件句，如果省略了if，从句中的“were, should, had”需要提前在主语之前。故选B。

3.他把儿子锁在屋里，以免他再次逃学。

A. He locked his son in, in case he play truant again.

B. He locked his son in, in case he played truant again.

C. He locked his son in, in case he might play truant again.

D. He locked his son in, in case he would play truant again.

3.【答案】A。解析：考查in case引导的虚拟语气。in case表示以免，用作虚拟语气，防止他儿子逃学，是对将来的虚拟，后面用主语+ should 动词原形，其中should 可以省略，故选A。
