考点7 考查不定式用作宾语补足语
能后接不定式作宾语补足语的动词很多，但中考英语中经常涉及的只有少数几个，即ask, tell, order, use, want, warn, wish等。如：
He asked me to get the car ready. 他叫我把车准备好。
The doctor told me to give up smoking. 医生叫我戒烟。
He ordered us to be quiet. 他命令我们安静。
People use a knife to cut things. 人们用刀切东西。
He warned me not to going out at night. 他警告我不要晚上出去。
My parents wanted me to have a good education. 我的父母想要我受到良好的教育。
注意，动词hope习惯上不用于以上类似表达，所以当表示汉语“希望某人做某事”时，不能用hope sb to do sth。如：
史密斯先生希望他所有的学生都能考及格。
误：Mr Smith hopes all of his students to pass the test. (ask.hxen.com)
正：Mr Smith hopes that all of his students can pass the test.

当需要强调时，可在不定式前加上in order或so as。如：
