非谓语动词第一、二、三课时

一、学情分析

非谓语动词在英语学习当中占了很大的比例，而学生时常不能很好地处理该部分知识点，经常分不清是什么是谓语，什么是非谓语，更搞不清楚什么时候该用谓语，什么时候该用非谓语；其中过去分词和现在分词的用法尤为混乱，不能很好地判断何种情况该用现分，何种情况该用过分；非谓语动词的相关练习做得不够多，综合运用能力较低。

3. 非谓语动词的种类和基本用法。

Step2: 动词不定式用法

一、不定式的语法意义：

I heard her sing. (唱和听见同时发生)

I expect to come back next Sunday.(“回来”发生在“预计”之后)

2.不定式完成式：表示的动作发生在谓语动词表示的动作之前；

He pretended to have reviewed his lessons.

I am glad to have met you before.

3.不定式进行式：表示的动作与谓语动词表示的动作同时发生；

She seems to be waiting for somebody.

When he came to see me, I happened to be taking a bath.

4.不定式完成进行式：表示的动作发生在谓语动词表示的动作之前，并延续到那个时候，可能仍在进行；

She is said to have been waiting a novel this year.

She seemed to have been working on a difficult maths problem.

5.主动语态：一般表示主动的意义，但有时也可以表示被动意义；

They began to learn Japanese last winter.

Some stars are too far to see.(= to be seen)

6.被动语态：表示被动的意义；

The composition contest is to be held next month.

She is anxious to be invited to the ball.

二、不定式的句法功能：

1.作主语：一般表示具体的某次动作。

1)不定式作主语时，谓语用单数：To do such things is foolish.

2)主系表结构：To see is to believe.

3)当主语较长，谓语较短时，常用it做形式主语，将不定式放到谓语的后面。

常用于下列结构中：

(1)It is/was +adj.+(of sb.) to do…（如goo d/ kind/ nice/ clever/ foolish/ selfish…）

(2)It is +adj.+(for sb.)+to do…（如easy / difficult / hard / / unwise / possible/ necessary…）

(3)It is +a/an +名词+ to do...（如a pity/ a shame / a pleasure /one’s duty / an honor …）

(4)It takes (sb.) some time / courag e / patience …to do…

(5)It requires courage / patience / hard work… to do…

2. 作表语：常表示将来的动作或状态。

Her wish is to become a lawyer.

3. 作宾语：ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用动词不定式作宾语。

注意:1.某些及物动词可用-ing也可用动词不定式作宾语但意义不同stop/ go on/ remember/ forget/ regret/ try/ mean….

2.某些及物动词think, believe, consider, feel, find, make等后常用it作形式宾语。4．作定语：当不定式的逻辑主语是句子的主语时，要用主动表被动。

Xiao Li is a very nice person to work with.

He wants you to be his assistant.

The pen is very nice to write.(用主动表被动)

5.作状语：表示目的、结果、原因和情况，不定式的逻辑主语通常是全句的主语；To make a living, he had to work from morning to till night. (目的)

6. 作宾语补足语：宾语是不定式的逻辑主语，不定式在表示知觉的动词和使役动词后，不用to ，在动词help后to可用可不用。这些动词有see, hear, feel, watch, notice; have, make, let等。但如果句子是被动语态，则to不可省略。

He asked me to help him.

She usually helped her mother (to) wash clothes on Sundays.

7. 同位语: Is this your purpose, to avoid being punished?

8. 独立成分: To tell you the truth, I don’t like you.

类似的有：to be frank坦率地说，to cut a long story short 长话短说，等等。

三、不定式的其他用法

1.“疑问词+不定式”结构，不定式可以和who, whom, whose, what, which, when, how, where, whether等连用，构成动词不定式短语，在句子中起名词作用，可作主语，宾语，
