不是啊
动词不定式在英语中的使用频率很高,可以作主语、表语、宾语、同位语、补语及独立成分等.带to的不定式是经常见到的,但有时也会遇到省略to的不定式.那么,什么时候可以省略to,什么时候又必须保留呢?这是大家学习不定式时的难点,下面笔者就常见的不定式的几种用法进行一下简单总结
一、不带to的不定式常见于以下几种情况:
1.如果主语是all或是what引导的从句,主语受first,only,one,least或形容词最高级修饰,且后面的从句或短语中有实意动词do时,作表语的不定式前不用to.如:
The only thing I can do was keep silent.
What he wants to do is complete the whole task as soon as possible.
All he does is study hard.
all作主语时,如果从句含有say,其后作表语的动词不定式有时可以省略to.如:
All they say is hurry up.
但在其他情况下,to不能省略.如:
All I wanted was to help him.
2.在一些固定搭配中,如:let go,make believe,go hang等,不用to.如:
We'll have to make do with dry bread. He made believe he was innocent. They can't let things go hang.
3.在would rather,would sooner(宁愿……也不),might (just) as well,cannot help but,cannot but (不得不),do nothing besides,do nothing but,do nothing than,had better,had best等结构后,用不带to的不定式.
The soldiers would rather die than surrender. I cannot but decline his offer.
He did nothing else than cry.
