初中英语语法知识（动词不定式）
1） 常在其后加动词不定式的动词有：afford , agree , ask , choose , decide , demand , expect , fail , hope , manage , offer , plan , pretend , promise , refuse , want ,would like , wish  , can’t wait 等。( 不定式作宾语时，如后有宾语补足语，常用 it 作形式宾语，而把不定式放在宾语补足语后。Eg. He found it very difficult to get to sleep . 主语+ think / find / feel +it + 形容词 + to do sth. 这一句型就是该知识点的体现。)
