求教,except后面能否接to do做介词宾语?

求教,except后面能否接to do做介词宾语? except后面是doing还是to do imagine后面是接to do 还是?求教 except to do sth except 后面的动词要用什么形式?要用doing 还是to do?例如：I want to do nothing except ______ my homework. I have no choice but to wait.I have nothing to do except sleep.这两句子中的but except.如何才能分析它是介词还是实义动词啊?来决定后面接不定式 ... 你在except 的区别上写错了吧?expect to do 期望做某事,不是except 吧? except加doing 还是加to do there is nothing to do except waiting还是there is nothing to do except to wait everybody except john was able to answer ..能否改成everybody was able to answer except john except to后面+动词原形还是动名词?为什么? settle down to 后面接do refuse 后面接doing还是to do aim后面接to do 还是doing 关于except和except to的疑问（1）He can do everything except cook（2）He didn't open his mouths except to complain.1和2都是用连接词except,倒是那些时候用接to,什么时候接原型呢? what do you except to learn in your English class except sb.to do有这个短语嘛? I can'to do anyting really except that!
