不定式和动名词做主语的区别
⒈不定式作主语
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.如:
To get there by bike will take us half an hour.
(2)用it作形式主语,把真正的主语不定式置于句后,常用于下列句式中.如:
①It+be+名词+to do
It's our duty to take good care of the old.
②It takes sb + some time +to do
How long did it take you to finish the work
③It+be+形容词+for sb +to do
It is difficult for us to finish writing the composition in a quarter of an hour.
④It+be+形容词+of sb +to do
It is stupid of you to write down everything the teacher says.
⑤It seems(appears)+形容词+to do
It seemed impossible to save money.
在句型③中,常用表示客观情况的形容词,如:difficult, easy, hard, important, impossible, necessary 等;在句型④中,常用careless, clever, good, foolish, honest, kind, lazy, nice, right, silly, stupid, wise等表示赞扬或批评的词.在不定式前的sb,可看作其逻辑主语.这一句式有时相当于Sb is+形容词+to do句式,如:It's kind of you to help me with my English.=You are kind to help me with my English.
⒉动名词作主语
Learning without practice is no good.
动名词作主语时,也常用It句式.如:
①It's +no good(no use, fun, a pleasure, a waste of time)+doing…
It's no good reading in dim light.
It's no use sitting here waiting.
②It's+形容词+doing
It's dangerous swimming in the sea in windy days.
这样用的形容词有expensive, nice, tiring等,但important, necessary则不适用于这种结构,应用不定式代替,如:It's important for you to keep fit.
③There is no + doing
There is no saying what will happen next.
在这一结构中,动名词后常带宾语,相当于"It's impossible to…"结构.
⒊动词不定式和动名词作主语的区别
①不定式作主语经常表示具体动作,常与特定的动作执行者联系在一起;而动名词作主语经常表示抽象动作,经常不与特定的动作执行者联系在一起.如:
It's no good eating too much fat.
It's no good for you to eat so much fat.
②动名词结构作主语,可以用名词或代词属格形式作逻辑主语.如:
It's no use your pretending that you didn't know the rules.
不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。
It took me only five minutes to finish the job.
○3在疑问句中，句首总用-ing形式，而不用不定式。
Does our saying mean anything to him? 我们说这话，对他能起作用吗？
○4动名词作主语时，通常用以表示一件已知的事或经验。
不定式短语通常用来表示一件未完成的事或目的。
Climbing mountains is interesting．爬山很有趣。(经验)
Driving a car during the rush hour is tiring．在高峰时刻开车令人厌烦。(经验)
不定式和动名词作宾语的区别
在一个句子中，用不定式，还是用动名词作宾语，往往是由句子谓语动词的用法来决定的。
英语中大多数动词既可跟不定式，也可跟动名词作直接宾语，但有些动词要求：
(1)不定式做宾语和宾语补足语

(3)有些动词后使用动名词和动词不定式作宾语的差别
1）forget to do 忘记要去做某事（此事未做）
forget doing忘记做过某事（此事已做过或已发生）
2）stop to do 停止、中断（某件事），目的是去做另一件事
stop doing 停止正在或经常做的事

remember doing记得做过某事(已做)
4) regret to do对要做的事遗憾
regret doing对做过的事遗憾、后悔
5）try to do努力、企图做某事

6) mean to do打算，有意要…
mean doing意味着
7）go on to do 继而（去做另外一件事情）
go on doing 继续（原先没有做完的事情）
8）propose to do 打算（要做某事）
proposing doing建议（做某事）
9) like /love/hate/ prefer +to do 表示具体行为；+doing sth 表示抽象、倾向概念
（注）如果这些动词前有should一词，其后宾语只跟不定式，不能跟动名词。例如：
I should like to see him tomorrow．
10）need, want, deserve +动名词表被动意义；+不定式被动态表示“要(修、清理等)”意思。
Don't you remember seeing the man before?你不记得以前见过那个人吗?
You must remember to leave tomorrow．你可要记着是明天动身。
I don't regret telling her what I thought．我不后悔给她讲过我的想法。(已讲过)

I didn't mean to hurt your feeling．我没想要伤害你的感情。
This illness will mean (your) going to hospital．得了这种病(你)就要进医院。
不定式，现在分词，过去分词与动名词做表语的区别（一）：
(1) 不定式作表语
1)不定式作表语一般表示具体动作，特别是表示将来的动作。
To do two things at a time is to do neither．--次做两件事等于未做。
What I would suggest is to start work at once.我的建议是立刻开始干。
2）如果主语是不定式（表示条件），表语也是不定式（表示结果）。
To see is to believe.百闻不如一见。
To work means to earn a living．工作就是为了生活。
3)如果主语是以aim，duty，hope，idea，happiness，job，plan，problem，purpose，thing，wish等为中心的名词，或以what引导的名词性从句，不定式作表语是对主语起补充说明作用。
His wish is to buy a luxurious car in the near future．他的希望是在不远的将来买一辆豪华轿车。
The function of Louis Sullivan's architecture was to provide large uninterrupted floor areas and to allow ample light into the interior.
The most important thing is to negotiate with them about the future of the plant．
(2)动名词作表语：动名词作表语，表示抽象的一般性的行为。
Our work is serving the people．我们的工作是为人民服务。
His hobby is collecting stamps．他的爱好是集邮。
(注)动名词作表语时与进行时态中的现在分词形式相同，但其所属结构迥异，进行时态说明动作是由主语完成的。动名词做表语，说明主语的性质或情况。
People cannot but feel puzzled，for they simply cannot understand how he could have made such a stupid mistake.
His victory in the final was no more convincing than I had expected．
(3)分词作表语
分词做表语有两种情况，一种是现在分词做表语，一种是过去分词做表语，这两者区别是考试中经常考到的地方。一般来说，表示心理状态的动词如excite，interest等都是及物动词，汉语意思不是“激动”，“高兴”，而是“使激动”、“使高兴”，因而现在分词应该是“令人激动的”、“令人高兴的”，过去分词则是“感到激动的”和“感到高兴的”。所以，凡表示“令人……的”都是-ing形式，凡是表示“感到……”都用-ed形式。换句话说，若人对……感兴趣，就是somebody is interested in...,若人/物本身有兴趣时，就是说sb./sth. is interesting.这类词常见的有：
interesting使人感到高兴--interested感到高兴的
exciting令人激动的--excited感到激动的
delighting令人高兴的--delighted感到高兴的
disappointing令人失望的--disappointed感到失望的
encouraging令人鼓舞的--encouraged感到鼓舞的
pleasing令人愉快的--pleased感到愉快的
puzzling令人费解的--puzzled感到费解的
satisfying令人满意的---satisfied感到满意的
surprising令人惊异的--surprised感到惊异的
worrying令人担心的--worried感到担心的
Travelling is interesting but tiring．旅行是有趣的，但是使人疲劳。
The pupils will get confused if they are made to learn too much．如果要学生学得太多，他们会感到糊涂的。
The argument is very convincing．他的论点很令人信服。
They were very excited at the news．听到这个消息，他们非常激动。
不定式和动名词做主语的区别 不定式和动名词都可在句子中作主语，一般说来, 有下面几点须给予注意： (1)不定式一般表示具体的、特定的行为，通常表示一种意愿、目的或者未完成的事情。；而-ing分词一般表示抽象的、一般的行为通常表示已经知道的事实或者经验。 如： To complete the program needs much effort. 完成这项计划需要很大的努力。 Riding a bike can make a man smart. 骑单车能使一个人敏捷。 (2)在疑问句中，只能用动名词的复合结构作主语。如： Is his speaking reasonable? 她的说话有道理吗？ (3)在某些句型中通常要用动名词短语作主语。如：It is no use doing…/ It is no goo d doing…/ It is useless doing…/ It is worthwhil e doing…如： It is no use talking your trouble to a man like him. 跟他那样的人谈你的烦恼没有用。 (4)一般说来，作主语和表语的非谓语动词形式应一致，即：或同时为不定式，或同时为-ing分词。如： Seeing is believing. 眼见为实(from https://www.doczj.com/doc/a54579001.html,)。 但是，在现代英语中，当表语用来说明主语的特定意义或具体内容时，主语和表语的非谓语动词的形式可以不一致，即，主语用动名词，而表语用动词不定式。如：Waving your hand is to say “Good-bye”. 挥手就是说“再见”。 Nodding your head is to say “Yes”. 点头就是说“对，是的”。
接不定式和动名词含义不同的动词 1. remember(记得)，forget(忘记)，regret(后悔)后接不定式指该不定式所表示的动作还未发生，后接动名词(有时可用完成式)，则指该动名词所表示的动作已经发生。比较。如：Remember to post the letter. 记住把这封信寄了。(“寄信”未发生) I remember posting the letter. 我记得寄了那封信。(“寄信”已发生) He forgot to pay me the money. 他忘记要给我付钱了。(“付钱”未发生) He forgot paying me the money. 他忘记曾给我付过钱。(“付钱”发生了) 2. try 后接不定式表示设法做某事，接动名词表示做某事试试(看有什么效果)。如： I’ll try to come tomorrow. 我明天设法来。 Let’s try knocking at the back door. 咱们敲敲后门试试。 3. mean 后接不定式表示打算(想要)做某事，接动名词表示意味着(要)做某事。如： He means to be a teacher. 他打算当老师。 He did not mean to hurt you. 他不是有意要伤害你。 This illness will mean going to hospital. 得了这种病就意味着要住院。 4. stop 后接动名词表示停止做某事，接不定式表示停下正在做的事去做另一事。如： He stopped speaking, and there was not a sound in the room. 他停止讲话，房里一点声音也没有了。 He stopped to listen, but there was no more sound. 他停下来听，但再也没有听到什么声音。 【注】后接不定式时，不定式不是宾语，而是目的状语。 5. can’t help后接动名词表示禁不住去做某事，接不定式表示不能帮助做某事。如： He couldn’t help crying when he heard the news. 他听到这个消息时禁不住哭了。 The medicine can’t help to get rid of your cold. 这药不能帮你治好感冒。 6. go on 后接不定式表示做完某事后接着做另一事，接动名词表示继续做正在做的事。如： You oughtn’t to go on living this way. 你不应该再这样生活下去了。 Go on to do the other exercises after you have finished this one. 做完这个练习后, 请接着做其他的练习。 【注】也人认为go on doing sth中的doing是现在分词而不是动名词。
动词不定式、动名词的用法和区别 动词不定式：动词不定式是由to + 动词原形构成，在句中起名词，形容词和副词的作用，可以担任除谓语以外的其它任何成分。 1. 动词不定式作主语： To mast a language is not an easy thing. / To teach English is my favorite. 动词不定式作主语时可以放在后面，而用it 作形式主语放在原主语的位置上。 It's very kind of you to have given us much help. 2. 动词不定式作宾语： 某些及物动词可以用动词不定式作宾语，这些动词有decide, begin, help, begin, want, wish, like, forget, learn, ask. I like to help others if I can. 3. 动词不定式作宾语补语。 We expect you to be with us. 我们希望你和我们在一起。/ Please ask him to come here quickly.请叫他快过来。 4. 动词不定式作表语： What I should do is to finish the task soon. / The most urgent thing is to find the boy immediately. 5. 动词不定式作定语： There are many ways to solve the problem. / I have something important to tell you. 6. 不定式作状语： We went to the hospital to see our teacher. / She is making a test to get a kind of useful medicine from a Tibet flower. 动词不定式的否定形式：not + to + 动词原形 The teacher told us not to swim in that river. 老师告诉我们不要在那条河里游泳。 It's unfair not to tell us. 没告诉我们真是不公平。 带疑问词的不定式： 疑问词who, what,which,when, where, how, why 可以加在不定式的前面，构成不定式短语，使含义更加具体。Where to go is not known yet. I don't know when to begin.。 Can you tell me where to get the battery. Do you know how to get to the station. 带逻辑主语的不定式： 动词不定式可以带有自己的逻辑主语，构成方法是：for + 逻辑主语+ 不定式。 注意：逻辑主语用宾格形式，for 本身无实际意义，它只表明后面的主语从逻辑上分析是不定式的主语。 It's necessary for us to help each other. / There are much work for me to finish, 动词不定式的被动形式：表示不定式动词同所修饰的名词是被动关系。 He is the man to be examined. 他是受检查的人。/ There are much work to be done. 有好多工作要做。 ●动名词 动名词是由动词原形+ ing 构成，同现在分词形式一样，在句中可作主语，宾语，表语和定语。 1) 动名词作主语： Talking like that is not polite. / Learning from others is important . / Putting on more clothes is not so good . （注：动名词可以象动词不定式一样，用it作形式主语，而把动名词写在后面做真正的主语。）It's no use waiting here, let's go home. / It's very difficult climbing this mountain. 2) 动名词作表语 The nurse's job is looking after the patients. 3)动名词作宾语 有些动词须用动名词来作宾语,它们是begin, mind, suggest, finish, stop, need, enjoy, miss, keep. Please stop smoking in the house. / I like reading in the forest. / Do you mind my opening the windows? 4）动名词作定语 She is studying in the reading room. / He slept in the sleeping bag. （动名词的否定形式：not + 动名词） He pretend not knowing it at all. 他假装全然不知。/ We considered not doing it now. 我们考虑现在不做这件事。 动名词的被动形式：当动名词和它的逻辑主语是被动关系时，用动名词的被动形式来表示。）His being looked down upon made him sick. / I can't really stand being treated like that.

动词不定式和动名词是英语非谓语动词的两个重要部分 一、作主语 1、不定式作主语：动词不定式可直接用作主语, 句子的谓语动词常用单数。 To get there by bike will take us half an hour. 对于主语较长的不定式，可以用it 作形式主语。例如： It's our duty to take good care of the old.How long did it take you to finish the work It is difficult for us to finish writing the composition in a quarter of an hour. It seemed impossible to save money.It's kind of you to help me with my English. 2、动名词作主语：动名词也可直接用作主语，或者用it 作形式主语。例如： Learning without practice is no good.It's no good reading in dim light.It's no use sitting here waiting.It's dangerous swimming in the sea in windy days.There is no saying what will happen next. 3、动词不定式和动名词作主语的区别 (1)不定式作主语经常表示具体动作，或者表示将要进行的动作。而动名词作主语经常表示 抽象的一般性的动作。例如：It's no good for you to eat so much fat. ( 有具体的人for you) It's no good eating too much fat. ( 泛指 ) (2) 不定式的逻辑主语常用 of, for 表示；动名词逻辑主语则常用物主代词、名词、代词表示。例如：It is stupid of you to write down everything the teacher says. (of you) It's no use your pretending that you didn't know the rules. (your) The doctor suggested them having their health check-up once a year. 二、作宾语 1、不定式作宾语 (1) 以下动词后 , 一般只用不定式作宾语 .如 :agree, attempt ， apply， ask, aim, arrange, beg ，choose, decide, demand, expect, fail , help, hope, lean, long, manage, offer, plan, prepare, pretend, promise, refuse, wish afford 等。 I decided to ask for my money back. I decided that I would ask for my money back. When our visit to the farm was over, we expected to start back on foot. When our visit to the farm was over, we expected that we would start back on foot. (2)不定式可先用 it 做形式宾语。 2、动名词作宾语 (1)以下动词后 , 一般只用动名词作宾语 , 如 :admit, appreciate, consider, delay, enjoy, finish, keep, imagine, mind, miss, practise, resist, risk, save, suggest, don't mind, give up, insist, on, put off 等。 I suggest spending our summer vacation in a seaside town. You must give up smoking, for it does too much harm to your health. (2)介词后只能接动名词做宾语 I should go to attend the birthday celebration instead of staying at home. What about inviting Li Jun to make a speech (3)少数特殊结构中只用动名词做宾语。它们可以看作是省略的介词的形式。例如： have difficulty prevent/stop (in) doing sth. have ?

动词的不定式,\分词\.动名词的区别及其用法、搭配。 答：非谓语动词包括动词不定式。动名词和分词三种形式,分词又包括现在分词和过去分词。这三种形式都是由动词变来的,但在句子中都不能作谓语,故这三种形式被称为非谓语动词。下面就这三种形式在用法上的区别浅析如下: 一、动词不定式和动名词在句子中均可作主语和表语 在表示一个具体的。个别的或将来的动作时,要用动词不定式。如: My job is to teach the first-year students grammar. To study English well is very important. 在表示比较抽象的一般的行为和动作时,二者可以互换。如: To climb mountains is a good form of exercise. Climbing mountains is a good form of exercise. 二、动名词、现在分词和动词不定式都可以作定语 1.动名词作定语时,和它所修饰的名词之间没有逻辑上的主谓关系,只表示被修饰名词的一般用途,必须位于名词之前。如: There is a swimming pool in our school. 2.现在分词作定语时,和它所修饰的名词之间有逻辑上的主谓关系,表示所修饰名词的特征。如: Listen to the singing bird. Who is the boy running towards us。 3.动词不定式作定语时,当所修饰的名词指人时,和它所修饰的名词之间有逻辑上的主谓关系。如: He is always the first to come to school. 当所修饰的名词指物时,和它所修饰的名词之间有逻辑上的动宾关系。如: I have a meeting to attend. 如果作定语的动词不定式中的动词是不及物动词,需加上相应的介词。如:
初中不定式和动名词 一、动词不定式：构成：to + 动词原形 1. 下列动词只能接不定式作： want 想要, agree 同意, choose 选择, decide 决定, expect 期望, hope 希望, earn 学会, need 必要, offer 提供, prefer 宁愿, +to do promise保证, plan 计划refuse 拒绝, wish 希望, would like想要 2. 下列动词只能接动名词（即动词+ing） Enjoy; mind; practice; finish；suggest ;deny; admit ; keep; spend; feel like + doing sth. enjoy doing sth., 喜欢做某事mind doing sth. 介意做某事, practice doing sth. 练习做某事finish doing sth. 做完某事 feel like doing sth. 想要做某事keep doing sth. 坚持做某事 have fun doing sth. 尽情做某事suggest doing sth.建议做某事 deny doing sth. 否认做某事admit doing sth.承认做某事 be/get used to doing sth. 习惯做某事look forward to doing sth. 盼望做某事 spend…(in) doing sth. 花费时间做某事can’t help doing sth. 情不自禁做某事 be busy doing sth 忙于做某事be worth doing sth 值得做某事 prefer doing sth. to doing sth 与…相比更喜欢做某事pay attention to doing sth. 注意做某事3．有些动词后面既可接不定式，也可接动名词，意思相同。如： begin/start to do sth.= begin/start doing sth开始做某事, like/love to do sth= like / love doing sth. 喜欢做某事; hate to do sth. =hate doing sth.憎恨做某事 4. 有些动词后接不定式或名词时，意思不同。如： 1）remember doing sth. 记得作过某事（某事已做过） remember to so sth.记住去做某事（某事还没做） 2）forget doing sth. 忘了作过某事（某事已做过） forget to do sth. 忘了去做某事（某事还没做） 3）try to do sth.=do one’s best to do sth. 尽力去做某事 try doing sth. 尝试做某事 4）stop doing sth. 停止做某事（停止正在做的事） stop to do sth.停下来做某事（停止的事去做另外的事） 5）go on doing sth. 继续做某事（同一件事） go on to do sth. 接着去做某事（不同的事） 5.下列动词跟动词不定式充当宾语补足语：vt.+sb. to do sth. vt.+ sb.+not to do sth. Want/ask/ tell /order/ allow/ wish/beg/advise / call /invite +sb. to do sth. She told me to buy a ticket.她让我去买张票 My mother often tells me not to go out at night. 6.help 后的不定式可带to, 也可不带to The teachers helped the students (to) learn English well. 那些老师帮助学生学好英语。 He often helps his mother (to) tidy up the room.他经常帮助他妈妈整理房间。
不定式和动名词作主语的区别： (1) 动名词作主语通常表示抽象动作；而不定式作主语表示具体动作。 Smoking is prohibited(禁止)here．这里禁止抽烟。(抽象) It is not very good for you to smoke so much．你抽这么多烟对你身体很不好。(具体) (2) 动名词作主语时，通常用以表示一件已知的事或经验。不定式短语通常用来表示一件未完成的事或目的。 Climbing mountains is interesting．爬山很有趣。(经验) Driving a car during the rush hour is tiring．在高峰时刻开车令人厌烦。(经验) To finish the task will take a long time.要完成这项任务将要花费很长时间。（具体） (3) 不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。 It took me only five minutes to finish the job. （4）动名词做主语往往表示普通的，一般的行为；不定式作主语常常表示某次具体的行为。 Collecting information about children's health is his job. 收集有关儿童健康的信息是他的工作。 It’s necessary to discuss the problem with an experienced teacher. 与一位有经验的老师讨论这个问题是有必要的。
2、常用不定式做主语的句型有： （1）It’s difficult (important, necessary) for sb. to do （2）It’s kind (good, friendl y, polite, careless, rude, cruel, clever, foolish, brave) of sb. to do. 3、常用动名词做主语的句型有： It’s no good (use, fun) doing. It’s (a) waste of time one’s doing.
动名词，分词和动词不定式的用法 (一)不定式和动名词作主语的区别 (1)动名词作主语通常表示抽象动作；而不定式作主语表示具体动作。 Smoking is prohibited(禁止)here.这里禁止抽烟。(抽象) It is not very good for you to smoke so much.你抽这么多烟对你身体很不好。(具体) (2)动名词作主语时，通常用以表示一件已知的事或经验。 不定式短语通常用来表示一件未完成的事或目的。 Climbing mountains is interesting.爬山很有趣。(经验) Driving acar during the rush hour is tiring.在高峰时刻开车令人厌烦。(经验) (3)不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。 It took me only five minutes to finish the job. (二)不定式、动名词和分词作表语的区别 (1)不定式作表语。 A.不定式作表语一般表示具体动作，特别是表示将来的动作。例： To do two things at atime is to do neither.一次做两件事等于未做。 What Iwould suggest is to start work at once.我的建议是立刻开始干。 B.如果主语是不定式(表示条件)，表语也是不定式(表示结果)。例： To see is to believe.百闻不如一见。
To work means to earn aliving.工作就是为了生活。 C.如果主语是以 aim,duty,hope,idea,happiness,job,plan,problem,purpose,thing,wish等为 中心的名词，或以what引导的名词性从句，不定式作表语是对主语起补充说明作用。例： The most important thing is to negotiate with them about the future of the plant.His wish is to buy aluxurious car in the near future. 他的希望是在不远的将来买一辆豪华轿车。 (2)动名词作表语：动名词作表语，表示抽象的一般性的行为。例： Our work is serving the people.我们的工作是为人民服务。 His hobby is collecting stamps.他的爱好是集邮。 〈注〉动名词作表语时与进行时态中的现在分词形式相同，但其所属结构 迥异，进行时态说明动作是由主语完成的。动名词做表语，说明主语的性质或 情况。His victory in the final was no more convincing than Ihad expected. (3)分词作表语。 分词做表语有两种情况，一种是现在分词做表语，一种是过去分词做表语。一般来说，表示心理状态的动词如excite,interest等都是及物动词，汉语注 解不是"激动"、"高兴"，而是"使得激动"、"使高兴"，因而现在分词应该是"令人激动的"、"令人高兴的"，过去分词则是"感到激动的"和"感到高兴的"。所以，凡表示"令人…的"都是-ing形式，凡是表示"感到…"都用-ed形式。换句话说，若人对…感兴趣，就是somebody is interested in.，若人/物本身有趣时， 就是sb./sth.is interesting。这类词常见的有： interesting使人感到高兴--interested感到高兴的
接不定式与动名词意义不同的动词有些动词后面既可接不定式也可接动名词，但意思明显不同。这类动词主要有以下几类： 第一类 remember, forget, regret：remember(记得)，forget(忘记)，regret(后悔)后接不定式表示动作尚未发生，后接动名词(可用一般式或完成式)表示动作已经发生。比较：Remember to post the letters. 记得把这些信寄掉。 I remember posting the letters. 我记得这些信是寄掉了的。 I forgot to tell him the news. 我忘告诉他这消息了。 I forgot telling her the news. 我忘了曾告诉过她这个消息。 She never regretted doing this. 她从没后悔这样做过。 I regret to tell you that he can’t come. 很抱歉他不能来。 第二类 go on：其后接不定式表示接着做另一事，接动名词表示接着做同样的事或不停地做着同样的事。如： Go on to do the other exercises after you have finished this one. 做完这个练习后, 请接着做其它的练习。 You oughtn’t to go on living this way. 你不应该再这样生活下去了。 She nodded, smiled, and went on stitching. 她点了点头，笑了笑，又继续缝衣服。 注：go on后接的doing也可视为现在分词而非动名词。 第三类 mean：其后接不定式表示打算做某事或有意做某事，后接动名词表示意味着做某事。如： To raise wages means increasing purchasing power. 提高工资意味着增加购买力。 I’m sorry I didn’t mean to be rude to you. 对不起，我并不想对你粗鲁无礼。 To mean to do something and to actually do something are two different things. 打 算做一件事和实际上做一件事完全是两回事。 第四类
既可接不定式也可接动名词，但含义完全不同的8个动词 有些动词只能接不定式做宾语，有些动词只能接动名词做宾语，正如前两天小简老师和大家分享的一样。还有一些动词即可以接不定式也可以接动名词做宾语，但含义不同，今天我们就来看看这样的动词都有哪些！ 1. remember to do sth. 记住要做某事（未做） remember doing sth. 记得做过某事（已做） Remember to close the door,please. 记着关门.
