介词情态动词动名词it 的用法疑问词组

考点名称:介词

  • 介词:
    是一种用来表示词与词、词与句之间的关系的虚词,在句中不能单独作句子成分。
    介词后面一般有名词代词或相当于名词的其他词类,短语或从句作它的宾语。

  • 介词的分类:
    (1)表示时间,处所:从 自 自从 于 打 到 往 在 当 朝 向 顺着 沿着 随着
    (2)表示方式:按 照 按照 依 依照 本着 经过 通过 根据 以 凭
    (3)表示目的:为 为了 为着
    (4)表示原因:因 由于 因为
    (5)表示对象,范围:对 对于 把 向 跟 与 同 给 关于
    (6)表示排除:除 除了 除去 除非
    (7)表示被动:被 叫 让 给
    (8)表示比较:比 和 同
    上述介词中的“着,了,过”是语素,不是动态助词。

  • 介词at, in, on的区别: 
    1. 表示时间,注意以下用法:
    (1) 表示时间的某一点、某一时刻或年龄等用 at。如:
    I get up at six in the morning. 我早上六点钟起床。
    He got married at the age of 25. 他 25 岁结婚。
    (2) 泛指一般意义的上午、下午或晚上以及月或年等较长的时间,一般用 in。如:
    We watch TV in the evening. 我们晚上看电视。
    He went to Japan in 1946. 他于 1946 去了日本。
    (3) 若表示星期几或某一特定的日期,则用 on。如:
    He left here on the fifth of May. 他于 5 月 5 日离开这儿。

    2. 表示地点、场所、位置等,注意以下用法:
    (1) 表示某一点位置,用 at。如:
    We live at No 87 Beijing Road. 我们住在北京路 87 号。
    The hospital is at the end of the street. 医院在这条街的尽头。
    与名词所有格连用表示地点,也用 at。如:
    at my sister’s 在我姐姐家  at the doctor’s 在医务室
    (2) 表示空间或范围,用 in。如:
    What’s in the box? 这盒子里有什么?
    He lives in Paris with his wife. 他同他妻子住在巴黎。
    但有时两者可换用。如:
    The meeting was held at [in] the hotel. 会议在宾馆举行。
    (3) at 与 in 的另一个区别是:at 用于指较小的地方,而 in 用于指较大的地方。如:
    in Shanghai 在上海    at the station 在车站
    但是,大与小是相对的,有时随着说话者的着眼点不同,大地方也可能用 at(比如把一个大地方看作一个点时)。如:
    Our plane refuelled at London. 我们的飞机在伦敦加油。
    We stopped for an hour at Moscow on our way to Paris. 我们在去巴黎的途中在莫斯科停了 1 个小时。
    (4) 介词 on 用于地点,主要指在某物的表面。如:
    What’s on the table? 桌上有什么?
    There’s a wallet lying on the ground. 地上有个钱包。
    注:在少数搭配中,也用介词 on。如:
    He works on a farm. 他在农场工作。

    3. 在某些搭配中,三者的区别与英国英语和美国英语有关:
    in the street (英) / on the street (美) 在街上
    in the road (英) / on the road (美) 在路上
    in the team (英) / on the team (美) 在这个队
    at the weekend (英) / on the weekend (美) 在周末
    at weekends (英) / on weekends (美) 在周末
    4. 有时三者的差别与搭配习惯和用法有关:
    in bed / on the bed 在床上
    in the tree (多指树外之物) / on the tree (多指树本身之物) 在树上

    介词besides,but,except的用法区别:
     1. 三者都可表示“除外”,但 besides 表示一种累加关系,意指“除了什么之外,还有……”;
    而 except 或 but 则表示一种排除关系,意指“除了什么之外,不再有……”。如:
    Besides his wife,his daughter also went to see him. 除他妻子外,他女儿也去看过他(即妻子女儿都去看过他)。
    Nobody went to see him except [but] his wife. 除他妻子外,没有一个人看过他(即只有他妻子去看过他)。
    注:在否定句中,besides 也表示“除……之外不再有…… ”,与but, except 同义。如:
    No one passed the exam besides [except] Jim. 除吉姆外,没一个人通过考试。

    2. 关于 but 与 except:
    (1) 两者都可表示“除……外不再有……”,但含义上略有差别:
    but侧重指意义的几乎完整性,而 except 则侧重指后面除去的部分。比较:
    All are here but one. 除一个人都到了。
    All are here except one. 还有一个人没到。
    (2) 在现代英语中,but 的介词用法十分有限,一般说来,它只能用在下列词语之后:
    ① no, no one, nobody, nothing, nowhere 等
    ② any, anyone, anybody, anything, anywhere 等
    ③ every, everyone, everybody, everything, everywhere 等
    ④ all, none 等
    ⑤ who, what, where 等
    Everyone knows it but you. 除你之外大家都知道。
    I haven’t told anybody but you. 除你之外,我没告诉任何人。
    No one but he [him] showed much interest in it. 除他之外没有一个人对此有很大兴趣。
    一般说来,若没有出现上述词汇,就不宜使用介词 but,否则可能造成错句。但是 except 却没有以上限制。比较:
    正:The window is never opened except in summer. 除夏天外,这扇窗户从不打开。
    误:The window is never opened but in summer.
    (3) but 一定不能用于句首,except 通常不用于句首:
    除我之外每个人都累了。
    正:Everyone is tired but (except) me.
    正:Everyone but (except) me is tired.
    误:But (Except) me, everyone is tired.
    注:except for 可用于句首,表示 except 的意思:
    正:Except for me, everyone is tired.

    3. 关于 except 与 except for:
    except 主要用来谈论同类的东西,而 except for 则主要用来谈论不同类的东西,有时含有惋惜之意。如:
    All compositions are well written except yours. 除了你的作文外,其他的作文都写得很好。
    His composition is good except for a few spelling mistakes. 他的作文写得不错,只是有几处拼写错误。
    注:若用于句首,则 except for 与 except 同义(但 except 通常不用于句首)。

    4. 关于 except for 与 but for:
    except for 主要表示排除,but for 主要表示一种虚拟条件(与虚拟语气连用)。如:
    Except for me, everyone passed the exam. 除了我之外,大家都通过了考试。
    But for my help, she would not have passed the exam. 若不是我的帮助,她就不会通过考试。
    But for the atmosphere plants would die. 如果没有大气,植物就会死亡。
    5. besides 除用作介词外,还用作副词,其意为“此外”、“而且”,可用于分句句首(通常用逗号隔开)或句尾。如:
    I don’t want to go; besides, I’m too tired. 我不想去,而且我也太累了。
    This car belongs to Smith, and he has two others besides. 这部车是史密斯的,此外他还有两部。

考点名称:情态动词

  • 情态动词:
    是一种本身有一定的词义,表示说话人的情绪、态度或与语气的动词,但不能单独作谓语,只能和其他动词原形构成谓语。
    无人称和数的变化,情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 “not”。
    个别情态动词有现在式和过去式两种形式,过去式用来表达更加客气,委婉的语气, 时态性不强,可用于过去,现在或将来。情态动词属非及物动词,故没有被动语态。
    情态动词有四类:    
    ①只做情态动词:must, can(could),may(might)……    
    ②可做情态动词又可做实义动词:need, dare   
    ③具有情态动词特征:have(had, has) to, used to    
    ④情态动词表猜测
    注:mustn't代表强烈禁止 must表示主观,have to表示客观。
    常用的有:can  may  could  must   have  use  .

  • 情态动词特点:
    情态动词无人称和数的变化,情态动词后面跟的动词须用原形,否定式构成是在情态动词后面加 "not"。
    个别情态动词有现在式和过去式两种形式,过去式用来表达更加客气,委婉的语气,时态性不强,可用于过去,现在或将来。情态动词属非及物动词,故没有被动语态。
    He could be here soon.他很快就来。
    We can't carry the heavy box.我们搬不动那箱子。
    I'm sorry I can't help you.对不起,我帮不上你。

    基本助动词与情态助动词最主要的区别之一是:
    基本助动词本身没有词义,而情态助动词则有自己的词义,能表示说话人对有关动作或状态的看法,或表示主观设想:
    What have you been doing since? (构成完成进行体,本身无词义)
    I am afraid I must be going. (一定要)
    You may have read some account of the matter. (或许已经)

    除此之外,情态助动词还有如下词法和句法特征:
    1) 除ought和used以外,其他情态动词后面只能接不带to的不定式。如果我们把ought to和used to看做是固定词组的话,那么,所有情态动词无一例外地只能接不带to的不定式:
    We used to grow beautiful roses.我们过去常常种这种漂亮的玫瑰花
    I asked if he would come and repair my television set.我问他是否来修我的电视机
    2) 情态助动词在限定动词词组总是位居第一:
    They need not have been punished so severely.
    3) 情态助动词用于第三人称单数现在时的时候,没有词形变化,即其词尾无-s形式:
    She dare not say what she thinks.
    4) 情态动词没有非限定形式,即没有不定式和分词形式,也没有相应的动名词:
    Still,she needn't have run away.
    5)情态助动词的“时”的形式并不是时间区别的主要标志。在不少场合,情态助动词的现在时和过去时形式都可以表示现在、过去或将来时间:
    Would you mind very much if I ask you to do something?
    She told him he ought not to have done it.
    6) 情态助动词之间是相互排斥的,即在一个限定动词词组中只能出现一个情态助动词,但有时却可以与have和be基本助动词连用:
    You should have washed the wound.
    Well,you shouldn't be reading a novel.
    7)情态动词must一般疑问句否定回答用needn't
    Must I read books every day、
    No,you needn't

  • 常见情态动词用法:
    1.can (could) 表示说话人能,可以,同意,准许,以及客观条件许可,could 为 can 的过去式。
    2.Must 必须,应该,一定,准是,表示说话人认为有必要做某事,命令,要求别人做某事以及对事物的推测。
    must 用来指一般现在时和一般将来时, 过去式可用 have to 的过去式代替。
    must + have + 过去分词,表示现在对过去事物的推测。
    must 和 have to 的区别:must 表示说话人的主观思想,have to 表示客观需要。
    3.need 是一个情态动词,他的用法完全和其他情态动词一样,但 need 还可当作实义动词使用,这时 need 就象其他动词一样,有第三人称,单复数, 后面加带 to 的动词等特性。
    needn't + have + 过去分词 表示过去做了没必要做的事情。
    4.dare 除用作情态动词外,更多的是当实义动词使用, 用法同实义动词一样,要考虑人称,单复数,时态等。
    5.ought 应当,应该。后面跟带有 to 的动词不定式。
    ought + to have done 句型。指过去动作,表示一件事情该做而未做。
    ought not to have done 句型。表示一件不该做的事情却做了。
    6.will (would)决心,愿望。 would 为 will 的过去式,
    will, would用于疑问句表示说话人向对方提出请求或询问,用 would 比 will 更婉转,客气。
    7.Shall、should 表示命令,警告,允诺,征求,劝告,建议,惊奇。
    8.have to,不得不,必须,表示客观条件只能如此,而must 则表示主观思想。

  • 情态动词功能:
    助动词主要有两类:基本助动词和情态助动词。
    基本助动词有三个:do,have和be;
    情态助动词基本的有十四个:may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to.had better 上述两类助动词的共同特征是,在协助主动词构成限定动词词组时,具有作用词的功能:
    1) 构成否定式:
    He didn't go and neither did she.
    The meeting might not start until 5 o'clock.
    2) 构成疑问式或附加疑问式:
    Must you leave right now?
    You have been learning French for 5 years, haven't you?
    3) 构成修辞倒装:
    Nowhere can he obtain any information about his sister.
    Hardly had he arrived when she started complaining.
    4) 代替限定动词词组:
    A: Who can solve this crossword puzzle?
    B: Tom can.
    A: Shall I write to him?
    B: Yes, do.

    情态动词表推测的用法小结   
    (一)情态动词表推测的三种句式    
    1.在肯定句中一般用must (一定),may(可能),might /can, could(也许,或许)。   
    (1)He must/may/might know the answer to this question?    
              他一定/可能/也许知道这个问题的答案。   
    (2)It is cold in the room. They must have turned off the heating.   
              屋里很冷,他们肯定把暖气关了。    
    2. 否定句中用can’t / couldn’t(不可能), may not/might not (可能不)。   
    (1)It can’t/couldn’t be the headmaster. He has gone to America.  这不可能是校长,他去美国了。   
    (2)He may not/might not know the scientist. 他也许不认识那位科学家。   
    3. 疑问句中用can/could (能……?)。    
     (1)Could he have finished the task? 他可能把任务完成了吗?    
     (2)Can he be at home now?  他现在能在家吗?   
    注:以上三种句式中情态动词的语气按程度都是依次递减的。Might, could并非may, can的过去式,而表示语气较为委婉或可能性较小。   

    (二)情态动词表推测的三种时态   
    1. 对将来情况的推测,用“情态动词 + 动词原形”。    
    (1)She must / may / might / could arrive before 5.  5: 00 前她一定/可能/也许到。    
    (2)She must/may/might/could walk miles and miles among the hills without meeting anyone.   
               她一定/可能/也许会在山里一连走好几英里而遇不到一个人。   
    2. 对现在或一般情况的推测,用“情态动词 + be”,“情态动词 +be doing”或 “情态动词 + 动词原形”。    
    (1)He must / may / might / could be listening to the radio now. 他一定/可能/也许正在听收音机。   
    (2)He can’t ( couldn’t ) / may ( might ) not be at home at this time. 这个时候他不可能/可能不在家。   
    (3)Mr. Bush is on time for everything .How can ( could ) he be late for the opening ceremony ?   
              布什先生一向准时,这次开幕式他怎么可能迟到呢?    
    3.对过去情况的推测,用“情态动词 + have +过去分词”。   
    (1)It must / may / might / could have rained last night .The ground is wet.  地湿了,昨晚肯定/可能/也许下雨了。   
    (2)The door was locked. He can ( could ) not / may ( might ) not have been at home . 门锁着,他不可能/可能不在家。   
    (3)Can / Could he have gotten the book? 难道他找到书了吗?    
    注:情态动词 should /ought to表推测时,意为“想必会,理应……”但与“have +过去 分词”连用时,则又可构成虚拟语气意为“本应该做某事却没做”。 
    例如:   
    (4)It’s seven o’clock. Jack should/ought to be here at any moment.   
         现在七点钟了,杰克理应随时到达。(推测)   
    (5)She should / ought to have attended your birthday party, but she had to look  after her mother in hospital. (虚拟)   
    她本该出席你的生日晚会的,可是她得在医院照顾她妈妈。   
    (6)Tom should not /ought not to have told me your secret, but he meant no harm.   (虚拟)   
    汤姆本不该告诉我你的秘密,可是他并无恶意。

考点名称:动名词

  • 动名词:
    如果一个动词加上了ing变成了名词,那么这个词称动名词。 动名词是一种兼有动词和名词特征的非限定动词。
    它可以支配宾语,也能被副词修饰。
    由于动名词是由动词变化而来,它仍保留着动词的某些特征,具有动词的某些变化形式,用以表达名词所不能表达的较为复杂的意念。
    动名词的名词特征表现在它可在句子中当名词来用,作主语、宾语、表语、定语。

  • 动名词的结构和形式:
    动名词的否定结构:
    动名词的否定结构由not 动名词组成。如:
    Trying without success is better than not trying at all. 实验没有成功也比不实验好。
    He hated himself for not having work hard. 他悔恨自己没有用功。
    I’m sorry for not having telephoned you before. 很抱歉,没有早给你打电话。
    He felt sorry for not having done the work well. 他为没有把工作做好感到难过。
    I fancy it has done you a lot of good not going. 我看不去对你倒好了。
    (not going 是动名词一般式的否定形式)
    There is no denying the fact that he si diligent.
    (no denying 也是动名词一般式的否定)

    动名词复合结构:
    通常情况下,动名词的逻辑主语为谓语动词的主语。如果动名词动作的发出者不失谓语动的主语时,则需要有自己的逻辑主语物主代词或名词所有格加动名词就构成了动名词的复合结构,这种结构在句中可以作主语,宾语等。
    (1)逻辑主语是有生命的名词作主语时,必须用名词或代词所有格,作宾语时(尤其在口语中),也可用名词普通个或人称代词宾格。如:
    Do you think my going there will be of any help?
    你看我去会有什么帮助吗?(宾语)
    The student’s knowing English well helps him in learning French.
    这位学生通晓英语对他学法语很有帮助。(主语)
    Do you mind my(me) smoking ? 你介意我抽烟吗?(宾语)
    They insist on Mary’s (Mary) going with them there.
    他们坚持要玛丽跟他们一起去那儿。(介词宾语)
    (2)逻辑主语是无生命名词是,通常只用名词普通格。如:
    Do you hear the rain pattering on the roof?
    你听见雨点打在屋顶上了吗?
    Is there any hope of our team winning the match ?
    我们对赢得比赛有希望吗?
    (3) 逻辑主语是指示代词或不定代词this that , somebody , someone , nobody, none, anybody, anyone 时,只用普通格。如:
    She was woken up by somebody shouting outside.
    她被外面喊叫的人吵醒了。

    动名词的形式(一般式,完成式和被动式):
    (1) 动名词的一般式所表示的动作与谓语动词所表示的动作同时发生,或在谓语动词表示的动作之后。如:
    We are very interested in collecting stamps. 我们对集邮很感兴趣。
    His coming will be of great help to us . 他来对我们大有帮助。
    但是有些明确表示时间的动词和介词 after, on,upon, 或for之后,常用一般式代替完成式,表示动作发生在谓语动作之前。如:
    I shall never forget seeing the Great Wall for the first time.我永远不会忘记第一次看到长城的情景。
    On hearing that bad news , the mother couldn’t help crying. 一听到这个糟糕的消息,母亲就禁不住哭了起来。
    Excuse me for coming late. 我来晚了,请原谅。
    Thank you for giving us so much help. 谢谢你给了我们这么多帮助。
    (2) 动名词的完成式所表示的动作或状态在谓语动词之前完成或结束。
    He regrets not having taken part in the work. 他后悔没有参加这项工作。
    We were praised for having finished the work ahead of time. 我们因提前完成了这项工作而受到了表扬。
    (3)动名词的被动式:当动名词的逻辑主语是行为承受者时,用被动语态。如:
    I like being given harder work. 我喜欢接受难点的工作。
    She is proud of being admitted into the university. 她为被大学录取而感到自豪。
    The meeting was put off without his having been consulted. 会议延期并未和他商量。
    He doesn’t mind having been criticized. 他不介意过去受到的批评。

  • 动名词与现在分词的关系:
    动名词它在形式上与现在分词相同,都是在动词原形的词末加-ing。在现代语法中,这两种形式同视为"-ing形式"。
    这两种形式的另一个相同之处是:
    它们都是由动词变化而成的,它们都保留了动词的某些特征,它们都能带自己的宾语、状语,而构成动名词短语或是现在分词短语去担当句子成分。
    例如:
    Speaking in the public,he will surely be very cheerful .
    (现在分词短语,作状语)他在公众场所讲话时总是兴高采烈的。
    She hates speaking in the public.
    (动名词短语,作宾语)她不喜欢在公众场所讲话。

    动名词和现在分词都可以用于系动词之后作表语,区别方法是:
    ①作表语的动名词与主语指的是同一件事,此时系动词相当于“是”,通常把主语和表语的位置互换,语法和意思不变,例如:
    My hobby is swimming.可改为Swimming is my hobby.(可将原句中的主语与表语位置互换)
    ②现在分词作表语主要用以说明主语的性质,不能与主语互换位置,例如:
    The story is interesting .不可改为:Interesting is the story.
    2.动名词和现在分词都可以用作定语来修饰名词,两者的区别在于:
    动名词修饰名词时主要表示该名词的用途,而现在分词修饰名词时性质、状态或动作等。试比较:
    ①a swimming boy和a swimming suit
    前者的意思是“一个正在游泳的男孩”,即a boy who is swimming,现在分词swimming 表示被修饰名词boy的动作;
    而后者的意思是“游泳衣”,即a suit for swimming,动名词swimming表示suit 的用途。
    ②a sleeping child 和 a sleeping car
    前者的意思是“一个正在睡觉的孩子”,即a child who is sleeping,现在分词sleeping 表示被修饰名词 child 正处于的状态;
    而后者的意思是“卧车(被用来睡觉的车厢)”,即 a car which is used for sleeping,动名词 sleeping 表示car 的用途。

  • 动名词用法口诀:
    动名词常泛指,句法作用宾/表/定与主,时态/语态之形式,一般/完成/被动式。
    Being done 系被动,不含任何进行意。用作主语请留意,常用it作形式主语,不指未来发生事,表达的信息系已知。
    用作表语请记清,作用相当一名词,检验方法很简单,主与表换位能成立。
    用作定语也易辩,表示名词之用途。
    用作宾语稍复杂,关键留意谓语动词(跟动名词作宾语的常用动词附后),时态同谓动作比较,先于谓动用完成式,其逻辑主语不固定,在句中/句外均有之。
    否定式其前加not,复合式其前加物主词,非句首宾格词也可用,尤其口语中更如此。
    说明:1、主-----主语 2、宾-----宾语 3、表------表语 4、定------定语 5、谓动---谓语动词

    动名词的用法:
    一、动名词作主语 
    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) ). (禁止吸烟)   
    No parking. (禁止停车)   
    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、动名词作宾语
    1.作动词的宾语   
    某些动词后出现非限定性动词时只能用动名词作宾语,不能用不定式。常见的此类动词有:
    admit, appreciate, excuse, stand, advise, allow, permit, avoid,  consider, enjoy, finish     
    They went on walking and never stopped talking.他们继续走,说个不停。 
    I found it pleasant walking along the seashore.在海滩上走真是乐事。   
    Mark often attempts to escape being fined whenever he breaks traffic  regulations.   
    每当马克违反交通规则时,他常常企图逃避罚款的处分。    
    2.作介词的宾语   
    We are thinking of making a new plan for the next term. 我们正考虑为下学期制定新的计划。   
    Shall we have a rest or get down to doing our work? 我们休息呢还是开始干活?   
    3.作形容词的宾语   
    The music is well worth listening to more than once.  这种曲子很值得多听几遍。   
    We are busy preparing for the coming sports meet. 我们正为马上到来的运动会忙着做准备。

    三、动名词作表语
    动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。
    表语、动名词与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。   
    Your task is cleaning the windows.   你的任务就是擦窗户。
    (Cleaning the windows is your task.)   
    What I hate most is being laughed at.  我最痛恨的就是被别人嘲笑。
    (Being laughed at is what I hate most.)

    四、动名词作定语
    动名词作定语往往表示被修饰词的某种用途。如:   
    a walking stick =a stick for walking=a stick which is used for walking   
    a washing machine=a machine for washing=a machine which is used for washing    
    a reading room=a room for reading=a room which is used for reading   
    a measuring tape=a tape for measuring=a tape which is used for measuring   
    sleeping pills=pills for sleeping=pills which is used for sleeping

  • 动名词是非限定动词的一种形式,由动词原形+ing构成。它既有动词的特征,又有名词的特征,故称。
    动名词也有时态和语态的变化,如表所示(以及物动词write为例),不及物动词没有语态的变化。
    时态、语态 主动 被动
    一般式 writing being  written
    完成式
    having written
    having been written

  • 动名词使用注意事项:
    1) 动名词做主语时,谓语动词为单数
    2) 在动名词和不定式中,作为介词的宾语是动名词
    3) 动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语
    例:I would appreciate you calling back this afternoon.
    4) 有些词后只能接动名词
    acknowledge;admit; advise;advocate;allow;appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny;
    detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can’t help;
    hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent;
    recall; report; resent; resist; risk; suggest; understand...
    5) 另外还有一些接-ing形式的常用说法
    it’s no good; it’s no/little/hardly any/ use; it’s not/hardly/scarcely use; it’s worthwhile; spend money/time; there’s no;
    there’s no point in; there’s nothing worse than; what’s the use/point
    6) 有些词后面加不定式和动名词均可
    remember,forget,try,stop,go on,continue,stop,regret,cease,mean后面均可用不定式和-ing形式,但意义截然不容。
    例:remember to do/doing:
    ①I remembered to post the letters.(指未来/过去未来将要做的动作)
    ②I remembered posting/having posted the letters.(我记得做过这个动作)
     forget与remember的用法类似。
     regret的用法:
    ①I regret to inform you that…(我很遗憾地通知你……)
    ②I regretted having left the firm after twenty years.(为了“二十年前的离开”而遗憾。)
     try to(努力)与try +–ing(试验):
    ①You really must try to overcome your shyness.
    ②Try practicing five hours a day.

    四、it用作形式宾语
    1. 基本用法
    当不定式、动名词、从句等复杂成分用作宾语且其后跟有宾语补足语时,通常会在宾语补足语前使用形式宾语,而将真正的宾语移至句末。
    其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”。如:

    it在强调句中的使用
    It is+被强调部分+that(who)+其他

    1. 请注意强调句型的特殊疑问句 
    2. 在强调原因状语从句时,只能强调由because所引导的从句。
    3. 在强调not … until结构时必须把not与until一起放到被强调的位置上。
    4. 注意强调句型与定语从句的区别。
    5. 不管被强调部分是单数还是复数,其前一律用It is / It was,而不能用They are / There were之类的。
    6. 被强调部分是指人时,被强调部分后可用that / who,被强调部分指物时,被强调部分后只能用that。
    7. 被强调部分是指时间或地点时,被强调部分后通常用that,一般不用when,where之类的。例:
    It is I who am right. 是我对。
    It was you that were wrong. 是你错了。
