写几个动词不定式作主语的句子,不要抄书上的。

1、不定式的逻辑主语是泛指的,不明确的人或人们。

a) To see is to believe.

b) To plan is to act.

c) It always pays to tell the true.

b) To point out the difficulties is my purpose. ( 不定式的逻辑主语是 “I”)

这些情况都可以放句首。

动词不定式作主语、宾语、定语、状语、补语的句子

一、作主语 (1)动词不定式作主语时,谓语动词常常用单数。

例如: To do morning exercises is useful for our health. 做早操有利于我们的健康。

To sweep the floor is my duty every day. 每天打扫地板是我的责任。

(2)如果动词不定式太长,常常用 it 作形式主语,而将真正的主语——动词不定式后置。

例如: It took me half an hour to walk there.我走到那儿花了半小时的时间。

It's important for us to learn English well.对我们来说,学好英语是重要的。

二、作宾语 (1)能够接动词不定式作宾语的有 ask, agree, beg, decide, determine, fail, hope, manage, offer, plan, prepare, pretend, promise, refuse, wish 及 would like/love 等动词,但 finish, enjoy, miss, appreciate, mind, advise, suggest 等动词后面通常只能接动名词作宾语。

例如: I hope to visit this place again. 我希望能再度访问此地。

She enjoys reading very much.她非常喜欢读书。

The driver failed to see the other car in time. 司机没能及时看见另一辆车。

(2)动词不定式与名等词构成复合宾语时,通常要用 it 作形式宾语,而将真正的宾语——动词不定式后置。

例如: I think it our duty to obey the laws. 我认为遵守法律是我们的义务。

I found it difficult to see him here. 我发现在这里见到他是很难的。

三、作补足语 (1)某些动词在主动式中后接动词不定式作宾语补足语;在被动式中,由于原来的宾语变成了主语,故原来的宾语补足语变成了主语补足语。

这类动词常用的有 consider, expect, tell, want, warn, wish,invite等。

例如:They told him not to be late again.他们告诉他不要再迟到了。

→He was told not to be late again. She invited me to have dinner with her yesterday.昨天她请我一起进餐。

(2)在feel(一感),listen to,hear(二听),let,make,have(三让),look at,see,watch,notice(四看)等词之后接不带to的不定式作宾语补足语,强调动作的完成过程;它们作被动句的谓语时,to要补上。

如:I heard her sing today.She sang wonderfully.今天我听见她唱歌了,她唱得非常精彩。

She was heard to sing today.今天有人听见她唱歌了。

She is often heard to sing this song(by us).我们经常听见她唱这首歌。

四、作状语 ⑴动词不定式作状语可表示目的、原因及结果等,其逻辑主语就是句子的主语,因此动词不定式作状语往往用主动式。

例如: Come to see me again soon. 尽快再来看我。

I trembled to think of it. 我一想到那件事就不寒而栗。

You couldn't do that to save your life. 你即使为了救自己也不能那样做。

(2) only to do sth. 与 only doing sth. 都可作表示结果的状语,区别是:only to do sth. 表示一个与主语愿望相反的或出乎主语意料的结果, 或用来暗示最初的未能实现的动作;only doing sth. 表示谓语动词本身的动作造成的结果。

例如: I worked hard, only to fail at last. 我努力工作,结果最后却是失败。

He died, only leaving nothing but debts. 他死了,只留下一身债 五、作表语 (1)动词不定式往往放在系动词be(,become, sound, taste 等系动词后面一般不接不定式)的后面作表语,表示将来的情况,说明主语的内容。

例如: My wish is to become a teacher.我的愿望是当一名教师。

Your job today is to clean the playground. 你今天的工作是打扫操场。

(2)如果系动词后的动词说明主语的性质,特征,相当于形容词。

这时就要用现在分词作表语,而不用不定式。

例如:He said that the story was interesting.他说这则故事很有趣。

六、作定语 (1)动词不定式常常放在名词或不定代词后面作后置定语,其逻辑主语往往是句子的主语,故动词不定式作定语时往往用主动式;如果动词不定式的逻辑主语不是句子的主语,该动词不定式要用被动式。

例如: Do you have anything to do tonight? 你今晚有什么事要做吗? I am going to Shanghai tomorrow. Do you have anything to be taken there? 明天我要去上海。

你有什么东西要捎去的吗? (2)动词不定式作定语往往表示尚未发生的动作,如果动作已发生或正在发生,一般用现在分词作定语。

例如: I have no pen to write with.我没有钢笔写字。

The man standing there is Li Ming. 站在那里的那个人是李明。

七、和疑问词连用:不定式前可用what,who,which,where,when,how,why等疑问词构成不定式短语,这种短语在句子中可作主语、宾语和表语等成分。

(1)作主语。

例如:When to start has not been decided. 什么时候出发还没定下来。

(2)作表语。

例如:The question is how to do the job well. 问题是怎样做好这项工作。

(3)作宾语。

例如:He told me where to find the book. 他告诉我了在哪找到这本书的。

Do you know how to play football? 你知道怎样踢足球吗?八、不定式的被动式 在初中阶段还涉及到动词不定式被动式的一般式,这种形式是由“to be+动词过去分词”构成的,表示“被……”之意。

例如:

动词不定式常常放在名词或不定代词后面作后置定语,其逻辑主语往往...

这句话讲的就是to-do动词不定式做后置定语时的两种情况.首先,定语都有其修饰的逻辑主语,当这个动词不定式做后置定语时,若其逻辑主语是整个句子的主语,则动词不定式用主动式,也就是直接to-do;如果动词不定式的逻辑主语不是整个句子的主语,该动词不定式要用被动式,也就是 to-be-done.

动词+ing形式当主语放在句子中有什么重点与要点

动名词是英语中动词的非谓语形式的一种,起名词的作用。

在动名词短语中,动名词还保留动词的属性,如可以带有自己的宾语、状语等。

一、动名词作主语的几种类型 动名词可以在句子中充当名词所能充当的多种句子成分。

在这里仅就动名词在句子中作主语的情况进行讨论。

动名词作主语有如下几种常见情况: 1. 直接位于句首做主语。

例如: Swimming is a good sport in summer. 2. 用 it 作形式主语,把动名词(真实主语)置于句尾作后置主语。

动名词做主语时,不太常用 it 作先行主语,多见于某些形容词及名词之后。

例如: It is no use telling him not to worry. 常见的能用于这种结构的形容词还有:better,wonderful,enjoyable,interesting,foolish,difficult,useless,senseless,worthwhile,等。

注意:important,essential,necessary 等形容词不能用于上述结构。

3. 用于“There be”结构中。

例如: There is no saying when he'll come.很难说他何时回来。

4. 用于布告形式的省略结构中。

例如: No smoking ( =No smoking is allowed (here) ). No parking. 5. 动名词的复合结构作主语 当动名词有自己的逻辑主语时,常可以在前面加上一个名词或代词的所有格,构成动名词的复合结构(——这时,名词或代词的所有格做动名词的逻辑主语)。

动名词的复合结构也可以在句中作主语。

例如: Their coming to help was a great encouragement to us. 二、动名词作主语与动词不定式作主语的比较 动词不定式和动名词都可以用作主语。

在意义上相近。

但动名词多用来表示泛指或抽象动作,不定式多用来表示特指或具体动作。

比较: Smoking is not good for health. It is not good for you to smoke so much. 注意: 1)在口语中,用动名词作主语位于句首的较不定式多见。

2)在“It is no use...”,“It is no good...”,“It is fun...”,“It is a waste of time...”等句型中,通常用动名词作真实主语: It is no use/good/a waste of time talking about that. *It is no use/good/a waste of time to talk about that. 3)在疑问句中,通常用动名词的复合结构,而不用不定式的复合结构作主语: Does your saying that mean anything to him? *Does for you to say that mean anything to him? 4)在“There be”句型中,只能用动名词,而不能用不定式作主语: There is no telling what will happen. It is impossible to tell what will happen. 5)当句子中的主语和表语都是非限定动词时,要遵循前后一致的原则,主语和表语在形式上要求统一: Seeing is believing. *To see is to believe. 参考资料:edu.sina.com.cn/en/2005-03-08/31436.html

动词不定式的应用范围

一. 作主语 例如: To be a doctor is hard. 做医生很难。

To learn English well is not easy. 学好英语不容易。

动词不定式(短语)作主语时,为了避免句子的头重脚轻,可以用“it”作形式主语,而把真正的主语--动词不定式(短语)放在句子的后部。

例如上面的句子可以表示为: It is hard to be a doctor. It is not easy to learn English well. 再如: It's important to plant trees in spring. 如果动词不定式的动作是谁做的,可以在动词不定式前面 加一个由介词for引导的短语,称为不定式的复合结构。

例: It's good for us to read English aloud in the morning. 对我们来说每天早晨大声读英语是很有益的。

It is important for students to use English every day. 对学生来说每天使用英语是很重要的。

二. 作表语: 动词不定式(短语)作表语常用于系词be的后面。

例: His work is to drive a car. 他的工作是开车。

My job is to feed animals. 我的工作是饲养动物。

Her ambition is to be a doctor. 她的理想是当医生。

三. 作宾语 动词不定式(短语)可以放在一些动词后面用作宾语,能以动词不定式作宾语的动词有:begin,start, want, forget, remember, show, learn, like, hate, love, ask等。

例: I want to tell you a story. 我想给你讲个故事。

They begin to work at eight every morning. 他们每天早晨8点开始工作。

Don't forget to lock the door. 别忘了锁门。

Would you like to go and have a picnic with us tomorrow? 明天和我们一起去野餐好吗? *如果and连接两个动词不定式,第二个动词不定式一般省“to”例: (1)He wants to go and have a swim with us. 他想和我们一起去游泳。

(2)若作宾语的动词不定式(短语)很长,可用it作形式宾语。

I find it interesting to learn English with you. 我觉得和你一起学英语很有趣。

He found it hard to catch up with others. 他觉得赶上别人很困难。

四. 作宾语补足语。

例如: The teacher asked us to read English for half an hour in the morning. 老师让我们早晨读半小时英语。

The teacher often tells Jim not to spend too much time playing computer games. 老师常告诉Jim不要花太多时间玩电脑游戏。

Please let me help you. 让我来帮助你。

动词不定式作宾语补足语,表示宾语所做的动作,可以用 动词不定式作宾语补足语的动词有:tell, ask, want, like, invite, encourage, help等。

但在let, make, see, watch, hear, feel, notice, have等感官听觉动词或使役动词后面作宾语补足语的动词不定式一般要省略动词不定式符号“to”,可以归纳为以下三种句式: 1.不可以省to的不定式作宾语补足语: tell /ask / want / would like / wish / like / invite /encourage /teach sb. to do sth. 例:The teacher told us to come earlier tomorrow. I want you to go now. 我想让你现在就走。

Her parents wish her to be a teacher. 她父母亲希望她当老师。

2.省“to”的不定式作宾语补足语: Let / make / have sb. do sth. Let the boy go out now. 让那个男孩出去。

The boy made the baby cry. 男孩弄哭了这个小孩。

see / watch / hear / notice / feel sb. do sth. I saw the students play basketball on the playground yesterday. 昨天我看见学生们在操场打篮球。

I often hear the girl sing in the next room. 我经常听到女孩在隔壁唱歌。

3.可省可不省的: help sb. (to)do sth. I often help my mother (to)do housework. 我经常帮妈妈做家务。

*动词不定式的否定式是直接在to之前加not. 例: (1)Tell them not to play football in the street. 告诉他们不要在街道上踢足球。

(2)省to的动词不定式的否定式是直接在动词前面加not. 例: Let the boy not go. 让那个男孩别走。

(3)如果将主动语态变为被动语态时,作宾语补足语的动词不定式变为主语补足语,动词不定式则不省“to”,即原来省的再加上,例: The boy made the baby cry. The baby was made to cry by the boy. 那个孩子被男孩弄哭了。

五. 动词不定式作定语 动词不定式作定语常用来修饰名词或不定代词,放于所修饰的词后,为后置定语。

例: Who was the first one to arrive?
