英语语法求救
1,I'm not sure which restaurant______
A,eating at B,to eat at C,for eating
填to eat at
麻烦帮我解释下具体原因
be sure 的后面接什么从句？宾语从句还是?

Answer 1

是选B
是疑问词+不定式作宾语.
1.如果不定式和疑问词之间有动宾关系,如果是不及物动词需要加上适当的介词.
对比：I don't know what to do next.
I don't know which one to choose.
2.be sure 的搭配：
be sure +of sth/about sth.
be sure to do sth
be sure that-cl
He is sure of success.=He is sure that he will succeed.他自信能成功.
He is sure to succeed.他肯定能成功.（说话者认为他能成功.）
祝你学习愉快!
