精选优质文档-倾情为你奉上前有do后无to的用法。具体参考如下:(1)连词连接两不定式前面的有do后面的to do的to省略,如: I have nothing to do but watch TV all day long. 短语:have nothing to dobut do. Tom have no choice but to give it up. 短语: have no choice but to do 在nothing but句型中,有do无to是指nothing 前有do的任何形式出现,but后的动词前就不能出现to,如:He did nothing but piddle away the time.他不做事,只是混日子。He could do nothing but stand and wonder.他只得惊奇地站著不动。 Jimdoes nothing but play basketball in the morning.
