1、巧记不定式省TO的口诀ByMs.Wang我们知道不定式可作主语，宾语，表语，定语，状语，也可作宾语补足语。作宾语补足语时，有时可加上不定式符号to,有时可省略to.那么什么情况下可加to,什么情况下不加to？在下列词语后的不定式作并宾补要加to:tellsb.todosth.,asksb.todosth.wantsb.todosth,ordersb.todosth.teachsb.todosth,wouldlikesb.todosth.allowsb.todosth,expectsb.todosth.encouragesbtodosth,ad

2、visesbtodosth.waitforsbtodosth,remindsbtodosth.但在有些词后面的不定式符号to可省这些词是：let(让），feel(觉得），notice(注意），help(帮助,既可加，也可省），两使（make,have),两听（listento,hear),四看（lookat,see,watch,observe).为了方便学生记忆，在教学中我把这些词编成口诀：不定式省to有习惯，只有动词11个半；让，觉得，注意和帮助，两使两听加四看。运用与练习1：用不定式填空⑴.Thebossmadetheboy-------
