含有think的主从复合句的反义疑问句的问题

doesn't he?

陈述部分--是think/believe/suppose (表示“认为；猜测”类动词)引导的复合句(即宾语从句)时，疑问部分：
○1当主句的主语是第一人称时，则和从句保持一致。如 I believe Miss Wang is right, isn’t she? / We don’t think you can answer so difficult a question, can you?
○2当主句的主语不是第一人称时，则和主句保持一致。如 He thinks he can mend this bike, doesn’ t he?

希望我的回答能够帮到你，望采纳！
祝你学习进步，天天快乐。O(∩_∩)O

五、 反意疑问句的陈述部分含有由带有定语从句或宾语从句的主从复合句，若其陈述部分为I(We) think(believe,have用作实义动词时，反意疑问句部分

He thinks she is a teacher,_doesn't he_______？
I think she is a teacher,_isn't she_______？
I don't think she is a teacher,__is she______？

疑问句部分的人称，时态与宾语从句保持一致。is she?
