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.
