Let me go to Beijing.
让我去北京吧。（go：不带 to 的不定式）

动词不定式有动词的属性，可以有自己的宾语、状语。
John told me to leave the office at once.
约翰让我立刻离开办公室。（the office：宾语；at once：状语 )
动词不定式在句子中不能用作谓语，因此也称为非谓语动词，但可用作主语、宾语、补语、表语、定语、状语等。虽然动词不定式在语法上没有表面上的直接主语，但它表达的意义是动作，这一动作一定由使动者发出。这一使动者可以称为逻辑主语。
动词不定式
1. 作主语
动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种：（1）把不定式置于句首；（2）用 it 作形式主语，把真正的主语不定式置于句后。
To get there by bike will take us half an hour.
骑自行车到那儿将花费我们半个小时。
It will take us half an hour to get there by bike.
骑自行车到那儿将花费我们半个小时。
动词不定式
2. 作宾语
动词不定式可以直接位于动词后作宾语，也可以和疑问词一起位于动词后作宾语。

I happened to know the answer to your question. 我碰巧知道你那道问题的答案。
Please show us how to do that. 请演示给我们如何去做。
The question is when to put it into practice. 问题是何时把它付诸实施。
动词不定式
3. 作宾语补语
有些动词在宾语之后还能跟不定式作宾语补语，即动词 + 宾语 + 补语（不定式）。有时可以先用形式宾语 it 代替不定式，把不定式置于补语之后，即动词 + it + 补语 + 宾语（不定式）。
I didn’t expect you to come so early. 我没想到你来得这么早。
Would you like us to go with you？你愿意我们和你一起去吗？
He feels it his duty to help the poor. 他觉得帮助穷人是他的责任。
I find it difficult to learn English well. 我发现学好英语很难。
动词不定式
4. 作表语
不定式作表语表示具体动作或将来动作。
My main purpose is to point out the difficulties of the matter.
我的主要目的是指出这件事面临的困难。
What I would suggest is to put off the meeting.
我会建议推迟会议。
动词不定式
5. 作状语
动词不定式可以作状语修饰动词、形容词、副词等，表示目的、结果、原因、条件等。
I come here only to say good-bye to you.
我来仅仅是向你告别。（目的）
He searched the room only to find nothing.
他搜查了房间，但一无所获。（结果）
I’m glad to see you.
我很高兴见到你。（原因）
To hear him talk in that manner, you would think him a foreigner.
听他那样说话，你会以为他是个外国人。（条件）
动词不定式
6. 作定语
动词不定式在句中作定语，置于被修饰的名词或代词之后。
The next train to arrive is from Washington. 下一辆到达的列车来自华盛顿。
Would you please give me some paper to write on 能请你给我一些写字的纸吗？
动词不定式
7. 动词不定式的时态、语态变化
动词不定式有进行时和完成时形式，也有被动语态。
动词不定式有进行时和完成时形式，也有被动语态。例如：
He seems to be eating something.

We passed/spent a pleasant hour. 我们度过了一个小时的愉快时光。

There seems to be no difficulty to be discussed. 看上去没有难点要讨论。
It seems that he doesn’t have much choice. 他似乎没有太多的选择。

了。
He appears/seems to be friendly. （√）
He looks to be friendly.（╳）
他看上去很友好。
动词词组的不同结构形式是决定不同基本句型的重要依据。英语的基本句型主要有五种。这些基本句型可以转换扩张成千变万化的句子。我们学习英语句子结构，应以基本句型为出 发点。英语的基本句型如下：
1. 主语 + 动词 + 补语（SVC）结构
The man is a teacher. 这位男士是教师。
George looks fine. 乔治看起来很好。
Dinner is at 6 o’clock. 晚餐在六点钟。
2. 主语 + 动词（SV）结构
