think
1.下面每组里的第一句比第二句普通：
- I think it a shame.
I think of it as a shame. - This used to be thought impossible.
This used to be thought of as immpossible.
注意不可没有of而有as，如不可说：
- I think it as a shame.
- This used to be thought as impossible.
2.下面四句意思相同：
- I think it a shame.
- I think it to be a shame.
- I think it is a shame.
- I think that it is a shame.
第三句和第四句比第一句和第二句通俗。
3.I do not think (that) it's going to rain today比I think (that) it's not going to rain today普通。
4.think后面接不定式作“想要…”，“以为将…”或“记着而做…”解。例如：
- He did not think to deceive us. （他不曾想要欺骗我们。）
- He did not think to meet us. （他不曾以为将遇到我们。）
- He did not think to ask us about you. （他不曾记着而向我们问起你。）
有人以为这种用法不算正当。
5.下面每组里的两句都可以说，注意think和know不可对调：
- Who do you think told me so?
Do you know who told me so? - Where do you think she lives?
Do you know where she lives?
6.下面每句里的how都该改作what：
- How do you think?
- How do you think of it?
- He told me how he thought about it.
7.下面三句意思相同：
- When she was alone, she thought the matter out.
- When she was alone, she thought the matter over.
- When she was alone, she thought over the matter.
下面几点该注意：
（1）第二句里的over是副词，第三句里的over是介词。think things out和think things over都可以说，但似乎不说think over things。
（2）think out着重在“彻底”，think over着重在“仔细”。
（3）think out a plan是“作出一个计划”，think a plan over或think over a plan是“再三考虑一个计划”。
8.下面两句都作“你想一想，（便可以知道）你的情况并不像你所说的那样坏”解：
- When you come to think of it, things are not so bad with you as you say.
- Come to think of it, things are not so bad with you as you say.
9.下面两句里的for可有可无，有人以为最好不用。
- His plan may prove better than you think (for).
- The weather has turned out as fine as we thought (for).
注意think for只用在比较级的后面。
10.think up作“想出”解，主要是美国英语。例如：Can you think up a reply? 和I must try to think up something to say.
11.下面各句里的think用作名词，是口语用法：
- You had better have another think.
- An occasional think might do you much good.
- My think is that you've consulted the wrong man.
