关于think用法的几点注意事项
1. 作谓语动词时，否定前移现象.类似的词有：suppose, believe, expect, imagine
I don’t think he will come.
I don’t imagine they will come if it rains.
I don’t think I know you.
2． 反意疑问部分主谓的选择. 当复合句的主语是第一人称，而谓语动词是think，believe, suppose,imagine, expect等表示认为，猜想，相信的词的一般现在时时， 反意疑问句的主谓与从句一致。
I think that it is a good thing, isn’t it?
I don’t suppose he cares, does he?
Compare：You never told us why his brother was thrown into prison, did you?
He says that it is true, doesn’t he?
This is the first time you have operated a computer, isn’t it?
3．双重疑问句. 对它的宾语从句中的某一部分提问时，语序应是疑问词+ +宾语从句其余部分。
和它这种用法相同的词还有say, suppose, imagine, etc.
What do you think the ocean bottom is made up of?
Which way do you imagine he went?
What do you imagine has happened to him?
Who do you think is fit for the job?
Whom do you think he lives with?
4 简单答语. So 作代词时，可以作宾语，用在动词think, hope, expect, suppose, imagine, believe 等的后面。
Do you believe he will come?
---Yes, I believe so./ No, I believe not./ I don’t believe so.
But: Will it rain tomorrow?
----I hope so./ I hope not
5. 过去完成时表“曾认为，本认为”。类似的词还
有hope, plan, want, expect, suppose, mean，Intend，wish.

关于否定转移的补充
1． 若否定不转移，则否定意义较强，因此语义不委婉。
2． 当 think以过去时，过去进行时或过去完成时，现在完成时或现在进行时出现时，不用转移。

3． 当 think前有副词修饰语时，不转移。
I often/always think that you are not fit for that job.
I really think you needn’t worry about his safety。
4． 当 think前有助动词do 表强调时，不转移。
I do think that you shouldn’t do that.
I do think it is wise of him to do so。
5. 当think用在疑问句中时。
Why do you think I can’t change your note.

6. 当think与情态动词连用时。

7．当宾语从句有no， never， hardly， 等否定副词时。
