宾语从句的否定转移
主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.
I don’t think he will come to my party.而不能说成I think he won’t come to my party.
我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?
我认为那个人不是Jim所杀的,是不是?
如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式.
We find that he never listens to the teacher carefully,does he?
我们发现他从来不仔细听老师讲课,是不是?

肯定的告诉你，无论第几人称。think都要否定转移。
人称和否定转移唯一有特殊变化的是体现在 反义疑问句上。具体可参考以下内容：

think，believe 等后接宾语从句的惯用法
有这样两个句子：1. I'm sorry, but I don't think I know you. 2. But I don't think we can go. 两句中的宾语从句的否定均转移到主句谓语动词上去了，这属于英语中的惯用法。为便于同学们将知识系统化，现将think, believe等动词后接宾语从句的有关惯用法归纳如下：
一、否定转移
当think, believe, suppose, imagine, expect等动词后接的宾语从句为含有not的否定句时，该否定应移至主句，即否定主句的谓语动词。例如：
I don't think it will rain tomorrow.
We don't expect our football team will win the World Cup.
但hope后接的宾语从句的否定不需要转移。例如：
I hope you weren't ill.
需要特别说明的是：涉及到转移的只是not，not以外的其它否定词，如no, never, hardly, few, little, seldom等，不必转移。例如：
I believe my brother has never been late for school.
We can imagine birds can hardly live without these woods.
二、反意疑问句的构成视情况不同有两种
think, believe, suppose, imagine, expect等动词后接宾语从句在构成反意疑问句时，视情况不同有两种不同的构成方式。
1.当主句的主语为第一人称时，其后的简短问句应与从句相一致。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，其仍属否定从句，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?
此类句子的回答同"前否后肯"型反意疑问句一样，如上述后一个句子，若双胞胎已经到了，则回答为"Yes, they have."；若尚未到达，使用"No, they haven't."。
2.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。例如：
Your sister supposes she needs no help, doesn't she?
You thought they could have completed the project, didn't you?
They don't believe she's an engineer, do they?
She doesn't expect that we are coming so soon, does she?
三、简略回答用so或not
口语中，可以用so或not替代这些动词之后的肯定或否定的宾语从句，以避免重复。例如：
1. - Are you able to come to our party tomorrow?
-I think so. What time? (so= I am able to come to your party tomorrow)
2. -Is my car ready?
-I believe not. (I don't believe so.)
这里的not = it is not ready；so = it is ready。
3. -Is Peter coming to the concert?
-I expect so/not.
需要说明的是，在think, imagine, believe三词的否定答语中，用don't think/imagine/believe so比用not更为常见。hope则只能使用not，不能使用don't hope so

收起

主句的谓语动词是think,believe,imagine,suppose,consider,guess等表示主观想法的动词时无论时态人称都需要否定提前，只是注意believe，suppose，consider，guess在否定回答时只能是主语+动词+not的形式
