非谓语动词分步讲解.docx

非谓语动词分步讲解一、非谓语动词的概念 动词的基本用法是作谓语。当句中已经有了谓语动词了，要选或要填的动词就只能用非谓语形式了。 非谓语形式有三种：1、动词不定式：to do 2、动词的ing : doing 3、动词的过去分词：done二、三种形式的含义（基本用法）不定式：表示目的和将来；动词的ing：表示主动和进行；过去分词：表示被动和完成。三、非谓语动词的时态和语态一般式 完成式 进行式不定式 主动 to do to have done to be doing被动 to be dong to have been done ing 形式 主动 doing having done 被动 being done having been done 过去分词 被动 done 四、非谓语动词的否定形式在非谓语动词前加not, never. 即 not / never to do, not / never doing 五、非谓语动词的复合结构不定式的复合结构：for / of sb. to do sth.动词 ing 形式的复合结构：宾格或所有格+doing (-ing 形式作主语时，用的所有格doing)六、非谓语动词的做题步骤1、判定是否用非谓语形式。方法：看看句子中是否已有了谓语动词了。2、找非谓语动词的逻辑主语。方法：非谓语动词的逻辑主语一般是句子的主语。3、判断主被动关系。方法：非谓语动词与其逻辑主语的主动还是被动关系。4、判断时间关系。方法：分析句子，看看非谓语动词所表示的动作发生在谓语动作之前、之后还是同时。之前常用 done; 之后常用to do; 同时常用doing。学习非谓语形式时，建议把三种形式一起来比较学习，会更加有效一些。一、非谓语动词作主语和表语的比较1、不定式和动名词作主语和表语a. 不定式表示一次性的、具体的动词。动词ing 常表示一般的、泛指的或习惯性的动作。如：_ is a good form of exercise for both young and old.A. The walk B. Walking C. To walk D. Walk(分析)a good form 暗示泛指一般的行为，用动名词作主语，选Bb. 不定式作主语时，常用it 作形式主语，即用句型：It is + adj. / n. + (for / of sb. ) to do sth. Its important for us to learn English well.Its kind of you to help us.注意：下面几个句型是用动名词：Its no good / use doing sth.Its useless doing sth. There is no need to do sth. 2、不定式、动名词、分词作表语的比较a、不定式、动名词作表语，.表示主语的内容。如：My job is teaching / to teach English. (teaching / to teach English 是my job的内容)Knowing who we are means knowing what we like to do.（主表语要用同一种形式）b、分词作表语记住：一些表示情感、情绪的动词，常用分词形式作表语。现在分词表示主语的性质特征，用过去分词表示主语的状态。常用动词：surprise (使某人吃惊)， surprising (令人吃惊)， surprised (主语)感到吃惊）类似动词有：excite (激动)，astonish (惊奇)，shock (震惊)，scare (惊恐)，disappoint (失望)，move（感动），如：The movie is exciting. We are excited at the news. c、在seem / appear (似乎，好像)， prove/ turn out (被证明是)， remain (仍然是，尚待)等连系动词后，可用不定式作表语。如：He seemed (to be ) very happy.Having a trip abroad is good for the old couple, but it remains _ whether they will enjoy it. (to be seen)二、不定式、动名词作宾语的比较1、只能接不定式的动词：a.（想要）want, would like, would prefer,ask, demand, intend, desire, b.(希望) wish, hope, expect,c.（决定）agree, decide, manage, promise, choose, continue, plan, prepare, make up ones mind, try ones best, offer, apply, d.happen, learn, fail, pretend, refuse, afford2、只能接动名词的动词：suggest, advise(建议), finish, mind(介意)，enjoy (喜欢)，appreciate (鉴赏，感激)，forbid禁止），avoid (避免)，cant help doing (忍不住)，risk (冒险)，feel like (想要)，delay, put off （推迟），give up (放弃)，be busy (忙于)，be worth (值得)，practise (反复练习)，3、接不定式和接动名词意义不同的动词：remember to do 记得去做，remember doing 记得做过 forget to do 忘记去做，forget doing 忘记做过了, regret to do 遗憾去做，regret doing 后悔做过, try to do 设法去做，try doing 试着做, go on to do 接着做另一件事，go on doing 继续做同一件事,mean to do 打算做，mean doing 意味着做, stop to do 停下来去做，stop doing 停止做,cant help (to) do 不能帮助做，cant help doing 忍不住做。如：In some parts of London, missing a bus means _ for another hour.A. waiting B. to wait C. wait D. to be waiting A4、表示未实现的愿望的动词,即表示本打算、想做，但事实上没做这些动词 plan, intend, mean, want, hope, wish, expect , 用 had planned to do sth. / planned to have done 来表示。Would like / love 只用would like to have done 如：I would love _ to the party last night but I had to work extra hours to finish the report.

A. being tied B. having tied C. to be tied D. tied D5、have 句型：have sb do sth, have sb/ sth doing, have sb /sth donehave sth done 表示两种意义：请别人做，而不是主语做；意外事故引起的。如：He didnt keep on asking me the time any longer as he had had his watch _.A. to repair B. repaired C. repairing D. repair B6、find + 宾语 + 宾补（doing / done）, keep +宾+doing, catch sb + doing (撞见某人在做)，smell sb +doing (察觉到某人在做)He looked around and caught a man _ his hand into the pocket of a passager.A. put B. to be putting C. to put D. putting D7、表示“认为”的 think, believe, consider, judge 等，常用句型：think sb (to be )+ adj. / n. , be considered to have done sth. 被认为已做了某事8、make oneself understood / heard / known , 即用了过去分词作作宾补9、句型 It is said / reported / thought / known that. 可变成：sb / sth be said / reported to have done sth. 如：Robert is said _ abroad, but I dont know what country he studied in.A. to have studied B. to study C. to be studying D. to have been studying A四、不定式、现在分词、过去分词作状语的比较 1、不定式作目的、原因、结果状语a.作目的状语：有三种形式，可互换：to do, in order to do, so as to do (不用于句首)b.原因：不定式常放在表示情绪反应的形容词后。如：happy, sorry, glad, sad, surpried, disappointed. 不定式不放在句首。如：I am sorry to hear that your father is ill.c. 结果：常用 only to do来表示末曾预料到或令人不快的情况，其动作发生在谓语动作之后。另外固定结构：too to do, enough to do, so / such as to do 中，不定式也作结果状语。d.在形容词后作状语，只用不定式如：The book is easy to read. (=It is easy to read the book.)We find the lake safe to swim in. (注意尾介词) 2、现在分词、过去分词可作时间、条件、让步、方式、原因、结果状语，就不作目的状语。注：表示时间、条件或让步的分词，有时可带上连词（if, unless, when, while, once（一旦） though, although）1）_ time, hell make a first-class tennis player.A. Having given B. To give C. Giving D. Given D2）I wont attend his wedding _ .A. unless invited B. if invited C. unless inviting五、三种非谓语形式作定语定语的比较 1、不定式作定语常表示“用要做”和“修饰the +序数词”。常用句型：have / there be / with +宾语+ to do 分析：以I have homework to do. 为例：不定式作定语有两种关系：a.主谓关系：I do homeworkb.动宾关系：to do 与 homework 构成动宾关系注意：以 Jack, do you have some clothes _? A. to wash B. to be washed 为例：分析：（1）动宾关系：wash clothes 成立；（2）主谓关系：You wash clothes成立吗？根据句意，显然不是。这里的洗衣服是说话做，而不是句子的主语you. 所以只能用不定式的被动式，选B。如：1）He gave me a book to read. 2）There are five pairs _, but Im at a loss which to choose.A. to be chosen B. to choose from C. to choose D. for choosing B(根据语境，可知是“有五双可供选择，即从5中选1，而不是选5)3）There are always people to _ if you feel like a chat.A. talk to B. talk C. speak about D. speak A(to talk 要与people构成动宾关系，要用短语 talk to / with sb) 2、分词作定语：单个的分词作定语，放在被修饰的名词前，而分词短语常放在后面。（1）They made efforts to bring stolen cultural relics back to China. (过去分词表被动和完成)(2) I want to write about people addicted to drugs.比较：a sleeping boy (= a boy who is sleeping); a swimming pool (= a pool for swimming)falling leaves (leaves that are falling); fallen leaves (leaves that have fallen down)a developing country (发展中国家)；a developed country (发达国家)3、to be done, being done, done 作定语的区别这三个都表示被动，就是时间不同。To be done 表将来，being done表同时进行，don
