He did nothing except () at the piano.except look but to look exc_英语解答

He did nothing except () at the piano.
except look
but to look
except to look
but looking
为什么选a,不选c啊,不是except to do么
还有but to do还是do是看but前有没有to么

解答

不定式动词在介词but,except,besides后面时,如果这些介词之前有行为动词do的各种形式,那么,这些介词后的不定式不带to,否则要带to.你这个句子except前面已经有一个did了,所以except后面不能加to
