据专家权威分析,试题“用括号中所给动词的适当形式填空。1.Our dog_____ (take) care ..”主要考查你对 被动语态,不定式,动名词 等考点的理解。关于这些考点的“档案”如下:
被动语态的构成: 被动语态的基本结构: 主语+be +过去分词(+by+动作的发出者) ① 一般现在时:am/is/are+过去分词 如:Trees are planted every year. ② 现在进行时 am/is/are+ being +过去分词 如:The road is being repaired. ③ 现在完成时 have/has + been +过去分词 如:The work has been finished. ④ 一般过去时 was/were + 过去分词 如:The story was told by him. Many birds were killed last year. ⑤过去进行时 was/were+ being + 过去分词 如: The new house was being painted when I got home. ⑥过去完成时 had +been+ 过去分词 如: He told me that the work had been finished. ⑦一般将来时 will +be + 过去分词 如:The problem will be discussed tomorrow. ⑧ 过去将来时 would/should +be +过去分词 如: He said that the Christmas tree would be put up soon. ⑨情态动词的被动语态 情态动词+ be +过去分词 如:The problem must be solved soon. Children should be taught to love animals.
被动语态使用注意: 1. 不及物动词无被动语态。 如:happen, break down, come out...... What will happen in 100 years. The dinosaurs disappeared about 65 million years ago. 2. 有些动词用主动形式表示被动意义。 如: write, sell, ride..... This pen writes well. This new book sells well. 3. 感官动词或使役动词使用省略to的动词不定式,主动语态中不带“to”,但变为被动语态时,须加上“to”。 例:make somebody do something→somebody+ be +made to do something see somebody do something→somebody +be +seen to do something A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by. The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss. 4. 如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定。 He gave me a book.→A book was given to me by him. He showed me a ticket.→A ticket was shown to me by him. My father bought me a new bike. →A new bike was bought for me by my father. 5. 一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词。 We can’t laugh at him. →He can’t be laughed at by us. He listens to the radio every day. →The radio is listened to by him every day. The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse. 构成be+done.
不用于被动语态的情形: ①不及物动词没有被动语态 这类动词有take place, happen, come about, break out, appear, disappear, last, arise等。 例如:A fire broke out during the night. ②某些静态动词不用于被动语态 这类动词有have, lack, fit, hold, suit, resemble等。 例如:My shoes do not fit me. ③宾语为相互代词和反身代词时不用于被动语态 例如:We should help each other.
关于主动形式表示被动意义: ①系动词(如look, sound, smell, feel, taste, prove等)要用主动表被动,因为系动词为不及物动词,它们没有被动语态形式。 例如:The building looks very beautiful. ②当open, close, shut, lock, move, read, wash, clean, cook, cut, wear, carry 等用作不及物动词且表示主语的某种属性时,通常用主动形式表示被动意义。 例如:The book sells well. ③有的动词本身含有被动意味,通常用主动形式来表示被动含义。 例如:Her eyes filled with tears. ④不定式to blame, to let用作表语时,通常要用主动表被动。 例如:Who is to blame? ⑤某些“be+形容词+to do”结构中的不定式通常要用主动形式表示被动意义。 例如:The book is difficult to understand. ⑥不定式用于某些动词(如have, have got, get, want, need等)的宾语后作定语时,如果不定式的逻辑主语就是句子的主语,通常用主动形式表示被动意义。 例如:Do you have time to help us? ⑦在too...to do sth.和...enough to do sth. 这两个结构中,若主语与其后不定式为to do sth.被动关系,则该不定式通常用主动形式表示被动意义(有时也可直接用 被动式)。 例如:The writing is too faint to read. ⑧be worth后的动名词要用主动表被动。 例如:This movie is worth seeing. ⑨在need, want, require等少数表示“需要”的动词后的动名词用主动形式表示被动意义。 例如:The house needs cleaning.
表示“据说”的三类被动句型: ①It is said that...句式 例如:It is said that thirteen is an unlucky number. ②There is said that...句式 例如:There is said to be plenty of oil off our coast. ③sb./sth.is said that...句式 例如:Mr. Brown is said to have died of liver cancer.
不定式的用法: 1、不定式作主语 例如:To remember this is very important. 注意:为了避免头重脚轻,在许多情况下,通常都将作主语的不定式置于句子后部,而在句首主语位置使用形式主语it。 例如:It is very important to remember this. 2、不定式作表语 例如:He seems to be ill. 注意:不定式作表语主要有三种情况,一是用于seem, appear, prove等系动词之后的不 定式(尤其是to be), 二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形, 三是表示想法、约定、义务、命令、可能性、命运等,如: You are to come when I call. 3、不定式作宾语 例如:I can not afford to buy a car. 注意: ①不定式不仅用作动词的宾语,还可用作个别介词(but, except)的宾语。 例如:I had no choice but to wait. ②当作宾语的不定式后跟有宾语补足语时,通常要用形式宾语it代替不定式,并将真正的宾语不定式置于宾语补足语之后 例如:I find it difficult to learn Japanese well. 4、不定式作宾语补足语 例如:Who taught you to drive? 5、不定式作定语 例如:I have a question to ask you. 注意:有的名词(如way, chance, right等)后用作不定式可换成of doing sth. 如:It is the best way to do (of doing) it. 但是以下名词后接不定式作定语时通常不能换成of doing sth. attempt courage decision effort fortune failure invitation wish 6、不定式作状语 例如:I went to France to learn French.
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
