近乎万能的动词不定式,几乎可以充当句子中所有的成分,它分为带 to 不定式和不带 to 不定式。其中,不带 to 不定式不要跟动词的基本形式混淆起来。一提到不带 to 不定式,相信大家大脑已经有一箩筐的语法知识在涌动,但是比较少的人知道 why 后面接不带 to 不定式的本质。一、常见的接不带 to 的不定式作直接宾语的是使役动词如 let,help 和 make 等,以及感官动词如 hear,see,feel 等,例如:Please let me go to the party, mom.His father makes him study.Jack is helping me clean the garage.I saw her look in my direction.二、had better 后面也可以接不带 to 不定式,相当于 should,建议一个必要或可取的行动,例如:You had better clean this up before your father gets home.I think we’d better go home soon.You had better listen to what I'm saying before you get yourself into more trouble.三、why 后面可以接不带 to 不定式的本质是句中隐含的成分被省略了,例如:Why study when I already know the material by heart?解析:完整的句子可能是 Why should I study when I already know the material by heart?Why watch TV when we could play outside?解析:完整的句子可能是 Why would we watch TV when we could play outside?
