反义疑问句什么叫肯定否定看主语人称时态看从句(例如：I do not think Tom is at home ,is he? ）

Question

谢谢！

Answer 1

I /We don't think Tom is at home, is he?
I/We think Tom is at home, isn't he?
Lucy thinks Tom is at home, doesn't she?
Lucy doesn't think Tom is at home, does she?
当主句是第一人称I/We...时，反意问句是针对后面的从句的主、谓。
当主句的主语是其它人称时：He/She/ You/ They think/ don't think that Tom....后面的反意问句是针对前面的主句部分的主谓。

Answer 2

此种说法一般用于宾语从句，当主句主语是第一人称时，且主句的谓语动词是表示人思维的词时，（think,suppose, imagine,believe....）,反义疑问句的主语要和从句的主语保持一致。例如:
(1) I think Tom was at home, was he?
(2) I do not thinkTom is at home, isn't he?
(3) I said Tom is at home, did I?
(4) He thinks that Tom is at home, doesn't he?.

Answer 3

我记得 主语是第一人称时，看从句
主语是第二，第三人称时，看主句
欢迎各位批评指正！

Answer 4

出现not,few,little,never等词，从句用肯定形式。如果主句中出现带有否定前缀的词，从句依然是否定形式。在做题时要遵循两个原则：前肯后否，前否后肯；一从二三主。
