中考英语考查不定式使用方法的核心考点
考试知识点一 try doing sth与try to do sth
try to do sth表示设法或尽力去做某事；try doing sth表示试着做某事看会不会有哪些结果或成效。如：
I’ll try to be more careful next time. 下次我要更小心一些。
Try holding your breath to sTOP sneezing. 试着屏住呼吸以止住打喷嚏。
考试试题实例：
—I didn’t hear you come in just now.
— That’s good. We tried ____any noise, for you were sleeping.
A. not make B. not to make C. to make D. making
剖析：选B。依据后面说的“你在睡觉”可知，前面是说“尽可能不要出声”，故用try not to do sth。
考试知识点二 asksb to do sth
用于这种句式最常见的动词是ask和tell，asksb to do sth的意思是“叫（告诉）某人做某事”。除ask, tell以外，以下动词也非常重要：persuade, wish, invite等。如：
He asked us to wait for him at the gate. 他叫大家在门口等他。
The teacher told the students to keep quiet. 老师叫学生安静。
They invited her to go for a walk. 他们请她一块去散步。
He persuaded his wife to change her mind. 他说服他老婆改变了主意。

3. —What are you going to do when you grow up?

考试知识点三 enough to do sth
enough to do sth一般用于形容词或副词的后面，表示“足够地……可以做某事”。如：

used to do sth指过去常常做某事；be used to doing sth指习惯于做某事。如：
