do nothing but do,后面的do有没有时态变化
do nothing but do后面接的动词没有时态的变化,直接+动词的原形。
【语法分析】:but 后面有时接带to的动词不定式,有时接动词原形(不带to的动词不定式),取决于句子前面是否已经有实意动词do.有相同用法的词还有except、besides。
当句子前面有do时,but后面跟的动词通常是原形,句子的结构是:
do nothing (anything) but+V-原形……;或者have……to do but+V-原形.当句子前面没有do时,but后面跟的动词通常不省略to。
【例句区分】:
I have nothing to do but (wait )for him. 因为but前面有了实意动词do,所以but后不加to。
She have no choice but (to accept )the fact. but前面的句子没有实意动词do,就要加to.
