there's nothing for them to do but ____ silence.
请问这空是填to remain 还是remain,各个感觉应该是填remain,因为前面有实义动词的do,后面不是应该省略to吗,但是答案是to remain.
There is nothing left to him but to hit back.此句我能理解
试比较：There is nothing left for him to do but hit back.而此句跟各位给出的there's nothing for them to do but to remain,到底应该用哪个呢？

there's nothing for them to do but ____ silence.请问这空是填to remain 还是remain,各个感觉应该是填remain,因为前面有实义动词的do,后面不是应该省略to吗,但是答案是to remain.There is nothing left to him but to hit ba
but 前面是to do,but后面要跟前面的一致,所以也应该是to do sth

to remain

除了保持缄默他们没有其他事可做
这里to do 和 to remain 是并列结构
他们一方面没事做一方面保持沉默
所以remain不是do的谓语，but作为并列连词作用和and是一样的。

这里的but是介词,其后常跟不定式做宾语.不定式是否带to的判定方法是;but之前有个行为动词do,but之后不带to
所以窃以为答案错了

to remain
