673 think的用法及否定转移问题

◎ think可以用作及物动词和不及物动词。

① 用作及物动词,表示“想,思考”。

I think (that)she should go there. 我想她该去那里。

② 用作及物动词,表示“认为”。结构为:

think sb./sth. to be+宾语补足语 (to be 可省)

be thought to be+主语补足语

think+that从句

think+it+宾语补足语+不定式或that从句

We thought him (to be)an honest man. 我们认为他是一个诚实的人。

(被动结构为:He was thought to be honest. to be 不可省)

I think her (to be)clever. 我认为她聪明。(被动结构为:She is thought to be clever. to be不可省)

I think it is our duty to help her. 我认为我们有责任帮助她。

I think it a good idea to go there. 我认为去那里是个好主意。

I think it best that you should come. 我认为你来最好。

This book is thought to be the best English grammar book. 这本书被认为是最好的英语语法书。

③ 作及物动词,表示“打算(做某事),想要”,结构为:

think to do sth. (用于肯定句、否定句)

think+that从句

think+what从句

We thought to go on a holiday. 我们本打算去度假的。

I didn't think to meet you here. 我没想到在这里见到你。

I can't think what you mean. 我想不出你的意思。

④ 用作不及物动词,表示“想,思考”。

First think,then speak. 先思而后言。

You have to think very quickly. 他应该快速思考。

⑤ 表示“考虑,对……有某种看法”时,think about和think of可换用。

She thinks too much about/of herself. 她过多地考虑自己。

I don't care what other people think about/of me. 别人对我有什么想法我不在乎。

I'm thinking about/of buying a bike. 我正在考虑买一辆自行车。

We have many things to think about/of. 我们有许多事情要考虑。

What do you think about/of the book?你认为这本书怎么样?

⑥ 当think about表示“回想(过去的事情)”,“考虑”某事、某计划等是否可行时,不可用think of替换。

Don't think about the past any more. 不要再想过去的事了。

I've thought about it for some time. 这件事我已经考虑一段时间了。

⑦ 当think of表示“关心,想出,想到;想要,打算;记得,想起,想念”时,不可用think about替换。

He is always thinking of others. 他总是替别人着想。

I can not think of a suitable reply. 我想不出一个合适的回答。

He longed for her return and thought of writing to her. 他盼望她回来,想写信给她。

Could you think of Tom,our old friend?你还记得我们的老朋友汤姆吗?

⑧ think of…as意为“把……看作,把……认为是”。

I think of it as the most important problem. 我认为它是最重要的问题。

It was thought of as possible. 它被认为是可能的。

⑨ think sth. over意为“仔细考虑”。

You'd better think it over. 你最好认真考虑一下这件事。

We have to think the matter over. 我们得仔细考虑这件事。

⑩ think后的宾语从句如果表示否定意义,要进行“否定转移”,即否定主句中的think,肯定从句。要进行否定转移的动词还有expect,hope,believe,imagine,suppose等。

I don't think it is necessary. 我认为这没必要。

I think I don't know you.

I don't think I know you.

我想我不认识你。

I think you are not right.

I don't think you are right.

我认为你不对。

⑪ 在用英文说话或造句时,应注意“时态迁移”,是指说话人在表述的同时某动作已经过去,就要用一般过去时,这种瞬间的时间变化,中文往往表达不出来。

I thought you were out. 我还以为你不在家呢。

I never thought you would send me a gift. 我从没想到你会给我送一个礼物。

I meant to call you,but I forgot all about it. 我本打算给你打电话的,可我全忘了。

I completely forgot. 我完全忘了。

I forgot that he was coming. 我忘了他要来的。
