医妃难求txt百度云:急!请问think of,think over与think about的区别及用法

think of 与 think about用法类似
考虑, 关心, 想起, 想象, 有...的看法, 记起

think of (about) 可以用来表示对问题的看法或考虑某件事：
表示“认为”时，不用进行时态

我认为这是不可能的。
What do you think about it?
你认为这件事怎么样？
I think that the doctor had better see you.

表示计划或想法时可以用进行时态。

think over
仔细考虑, 重新考虑
比起think of 与 think about更深入的考虑

think up，think out，think over，think of.
think up，think out侧重于思考的结果，即是否想出了办法、计划等；
think up主要表示“设想、构思”之意；think out主要表示“仔细思考并研究出（计划等），或者想透问题”等，两个短语均为动副结构；think over也为动副结构，侧重于思考，不涉及结果，表达“深思熟虑，仔细思考”之意；think of主要表示“考虑，关心，想起，对……有某种看法”之意，为动介（动词十介词）结构。表示看法、评价之时，常用一些副词来修饰，如think much／a lot／a great deal／highly／well／ill of…（对……评价高／好／不好）；若问评价如何，觉得怎样，常用what…think of…；若表示“以为，认为”时，则用think of…as。e．g．
