几道英语的反义疑问句想问下怎么做，可以的话顺便说一下句子中的主语和宾语分别是什么

Question

I think she isn't good,—— ——？
l don't think she is good,_____ _____?
l don't think she isn't good____ _____?

Answer 1

主句是I think，I believe，I suppose，I imagine，I expect时要反问从句，其余句式均反问主句。例如：I expect our English teacher will be back this weekend, won't she/he?We suppose you have finished the project, haven't you?值得注意的是，当这些动词后接的宾语从句的否定转移到主句时，其仍属否定句，故其后的简短问句应用肯定式，而非否定式。例如：I don't believe that he can translate this book, can he?We don't imagine the twins have arrived, have they?当主句的主语为第二、三人称时，其后的简短问句则应与主句相一致（此时，否定只看主句，与从句无关）。例如：Your sister supposes she needs no help, doesn't she?They don't believe she's an engineer, do they?

I think she isn't good,is she?主语：I 宾语从句：she isn't good
l don't think she is good,is she?主语：I 宾语从句：she is good
l don't think she isn't good,isn't she?主语：I 宾语从句：she isn't good
