教学过程
动词的非谓语形式:动词不做谓语时的固定形式。
(1)动词的非谓语形式: to do; doing; done 不能单独做谓语。
(2)动词不定式:
① 形式: to do 否定为 not to do
它的疑问形式是:“wh-疑问词+to+动词原形”。*它的被动形式:“to be +过去分词”。*它的完成形式:“to have +过去分词”。
动词不定式可以放在谓语前句子作主语。但是通常将作主语的动词不定式或不定式短语放在谓语后面,而在主语位置用“it”作形式主语(有时在不定式的前面还会用for sb.表示不定式的逻辑主语)。
如:To help animals is helping people.(帮助动物就是帮助人)/
It is very difficult (for us) to learn Chinese well.((对于我们而言)学好汉语是非常的困难)/
It took me half an hour to work out this problem.(解出这道题花了我一个小时的时间)
④ 动词不定式可以作谓语动词(及物动词)的宾语。
[A] 及物动词+不定式一般形式:want(想) / try(试图) / decide(决定) / would like(想要) / hope(希望) / love(喜爱) / learn(学会) / afford(提供) / agree(同意) / fail(失败、未能) / mean(意味着) / prefer(宁愿) / wish(希望)
forget(忘记) / remember(记得)/ like(总爱)
[比较] He forgot to turn off the light.(他忘了关灯.) (没关)/ He forgot turning off the light.(他忘记关过灯.)(关了) / Please remember to ring me up.(记得给我打电话.)(还没打电话) / I remember calling you yesterday but you forgot.(我记得昨天给你打电话了,但是你忘记了.)(打过电话)
[B] 及物动词+疑问词+不定式:
如:He does not know which one to take.(他不知道该选哪个)/ Tell me how to get to the station.(告诉我怎么样去火车站)/ She asked me what to do for today’s homework.(她问我今天家庭作业做什么)/ Can you teach me how to search the internet?(你能教我怎样上网吗?)
[C] 不定式作宾语而后面又有宾语补足语时,通常用it代替作形式宾语,而不定式则后置。如: I found it not very easy to learn to ride a bike.(我发现学骑车不很容易)
⑤ 动词不定式可以在句子中用作定语,放在名词或代词后面。
[A] 记住下面的一些结构:
被修饰部分 + 不定式(作后置定语)
汉 语 意 思
a key
to lock the door
锁门的钥匙
a box
to hold these things
装这些东西的箱子
give her a book
to read
给她一本书读
Is there any (+名词/代词)
to (do)?
有…要(做的)吗?
It’s time
to go.
是走的时间了。/ 该走了。
Do you have any work
to do?
你有工作要做吗?
I’d like something
to eat.
我要点儿吃的。
I have nothing
to say.
我没有话要说。
Would you like something
to drink?
你要点儿喝的吗?
[B] 在这种情况下,如果不定式动词是不及物动词,则后面必须加介词。如:
They could not find a place to live in.(他们找不到住的地方)/ Please give me a chair to sit on.(请给我一张椅子坐坐)/ He has got a writing brush to write with.((他找到了写字的毛笔)
⑥ 动词不定式可以在句子中用作状语,有下列几种情况:
[A] 放在不及物动词(come, go, stop, finish, wait等词)的后面。如:He came to see her yesterday.(他昨天来看望她)(表示来的目的)/ I stopped to have a rest.(我停下来休息一会儿)(表示停下来的目的)
[B] 放在完整的谓语之后(即“谓语+宾语”、“谓语+宾语+补语”、“动词+表语”之后)。如:We cleaned the room to let him play in it.(我们打扫了房间以便让他在里面玩)/ I opened the window to see more clearly.(我打开窗子以便看得更清楚点儿)
[C] 有时表示目的的不定式短语可以放在句首。如:To arrive there on time,I got up one hour earlier than usual.(为了按时到达,我们比平时早起了一个小时)(表示早起的目的)
[注意] stop to do 与stop doing的不同。如:They stopped to have a look.(他们停下来看看)(不定式作“停下来”的目的状语)/ They stopped looking out of the window and began to listen to the teahcher.(他们停止向窗外望,开始听老师讲课)(动名词作宾语,表示“停止”的内容)
⑦ 动词不定式可以在句子中用作表语,限用于连系动词之后。如:My job is to keep the goal.(我的工作就是守住球门)
⑧ 动词不定式可以在句子中用作复合宾语中的宾语补足语。
谓 语 动 词(vt.)
+ 宾语 (人 / 物)
+不定式 (作宾语补足语)
ask(请) / tell(关照) / teach(教) / want(想要) / would like(想要) / get(让) / help(帮) / invite(邀请) / like(喜欢) / warn(警告) /
+sb. / sth.
+to (do)
make(使得) / let(让) / hear(听) / see(看) / feel(感觉) / watch(观看)/ have(使得) / help(帮助)
+sb. / sth.
+ (do)
如:Mum asked me to help her with the cooking.(妈妈叫我帮助她做饭)/ I would like you to see my parents.(我想要你见见我的父母)/ The boss often made the workers work 14 hours a day.(老板常让工人们一天工作14小时)/ Now let me hear you play the violin.(现在让我来听你拉小提琴)
[注意] help之后做宾补的不定式符号to可以省略;hear / see / feel / watch之后的宾补用不定式与现在分词时,含义不同,需特别注意,(参见现在分词部分)。试比较:
I heard her crying when I walked past.(我路过时听到她正在哭)(指当时瞬间的情况)
I sat near her and heard her sing the new song.(我坐在她附近听她唱新歌)(指整个过程)
(3)动名词
① 动名词由动词原形加词尾“ing”构成。动名词有动词的特征,可以跟宾语,可以被状语修饰;它也有名词的特征,在句子中可以作主语、宾语(包括介词宾语)等。动名词加相关词语(宾语或状语等)构成动名词短语。
② 动名词可以作主语。一般可用it作形式主语而将动名词短语后移。如:Learning English all by yourself is not so easy.(自学好英语不那么容易)(=It is not so easy learning English all by yourself.)
③ 动名词可以作宾语。
[A] want / need之后用动名词时,含有被动意思。如:Your car needs reparing badly.(你的车急需修理。)(被修)My hair needs cutting.(我要理发。)(头发被理)
[B] remember / forge / stop / finish之后用动名词时,与用不定式含义不同。如:I forgot to write a letter to him.(我忘了给他写封信)(根本没写) / I forgot writing a letter to him.(我忘了给他写过信)(写了却忘了) / They stopped to look back.(他们停下来向后看)(停下的目的是向后看) / They stopped looking back.(他们停止向后看)(不向后看了)
[C] enjoy / mind / keep / hate/ go等词一般用动名词作宾语。如:Do you mind my closing the door?(把门关上你介意吗?)/ She hates travelling by air.(她讨厌坐飞机旅行)/ They went swimming every afternoon.(他们每天下午去游泳)/ I enjoy walking around the town.(我喜欢在镇上转悠)
[D] like / love / start / begin / learn后面用动名词时,与用不定式意思相近或相同。如:We began to study English when we were at primary school.(我们在小学时就开始学英语了) / We began studying English when we were at primary school. (我们在小学时就开始学英语了)
④ 动名词可以作表语,此时特别注意不要与现在进行时混淆。如:My job is putting these parts together.(我的事情是把这些部件拼起来) / I am putting these parts together.(我正在把这些部件拼起来)
⑤ 动名词与现在分词构成相同,但是含义不同,动名词主要表示事情,而现在分词则主要表示进行着的动作。如:Eating too much is not good for your health. (动名词短语,作主语) / Seeing is believing.(动名词短语,分别作主语和表语) / He ran after a moving bus and got onto it.(现在分词,作定语) / His father saw him sitting on some eggs.(现在分词,作宾补)
(4)分词: 包含现在分词和过去分词。(高中学习重点)
① 主要区别:现在分词一般有主动的意思或表示动作正在进行的意思;过去分词有被动或动 作已经完成的意思。分词可以有自己的宾语或状语。
② 分词或分词短语在句子中作定语、状语和复合宾语等。
[A] 作定语:分词作定语时,一般要放在修饰的名词之前,分词短语作定语时,则要放在所修饰的名词之后。 如:I have got a running nose.(我流鼻涕) / The woman running after the thief shouted very loudly,“Stop the thief!”(跟着小偷追的妇女大喊:捉小偷!) / Yesterday I met a man called Mr. Black.(昨天我遇见了一个名叫布莱克先生的人)/ He only gave me a broken glass,so I was very angry with him.(他只给了我一个坏玻璃杯,所以我很生他的气)
[B] 现在分词可以作下列动词的宾语补足语。(参考不定式作宾语补足语)
谓语动词(vt.)
宾语
宾语补足语
keep(保持) / see(看到) /
hear(听到) / watch(注意到) / feel(感觉到)
sb./sth.
(do)ing
如:Mum kept me working all the week.(妈妈让我一个星期都在工作)/ When I entered the room,I saw Jack eating a big pear.(我进入房间时看到杰克正在吃一只大梨子)/ In the dark I felt something very cold moving on my foot.(黑暗之中我感到有个冷的东西在我的脚上移动)
[C] 现在分词可以作状语,表示伴随情况。如:She came into the classroom,holding a pile of papers in her hand.(他走进教室,手上抓着一沓纸)/ I am very busy these days getting ready for the coming oral test.(这些日子我正忙着准备即将来到的口语考试)
[D] 过去分词可以作表语,放在连系动词后面,但要注意不要与被动语态混淆,“主系表”主要表示状态,而被动语态则表示动作。常用过去分词作表语的结构有:be worried (焦虑) / be pleased (高兴) / be tired (疲劳) / get dressed (打扮好) / get lost (迷路) / get caught (遭遇) / beome frustrated (沮丧) / become intereted in (对…感兴趣)等等。例略。
[E] 过去分词可以作宾语补足语。如:I had my hair cut this morning.(今天早上我让人给我理了发)(注意:have sth. done表示动作由别人来做,而have done sth.则为现在完成时的结构,两个结构不可以混淆)
8、动词用法辨析:
(1)“Why not+动词原形+…?”(干嘛不……?)是简略句,完全形式是:Why don’t you +动词原形+…?如:Why not go and have a look?(干嘛不去看看?
(2) seem(好象)的用法:记住几个结构:①sb./sth. + seem + (to be+)形容词+…;②sb./sth. + seem + like +…;③sb/sth + seem + to (do);④It seems that + 从句。如:He seemed (to be) very happy when he was called by the headmaster. (被校长叫到名字时他好象很开心) / It seems that nobody else could do such a foolish thing except Jim. (除了吉姆好象没有什么人会做出如此愚蠢的事情来)
(3) be afraid(害怕)的用法:记住几个结构:①be afraid of sth; be afraid of (doing); ②be afraid to (do); ③be afraid that+从句。如:She is a little afraid of snakes.(她有点怕蛇)/ Don’t be so afraid to stay at home alone at night.(别害怕晚上一个人在家)/ I’m afraid that somebody will take his place because of his serious mistakes.(恐怕有人要取代他了,因为他犯了那么大的错误)
(4) be sorry(抱歉)的用法:记住几个结构:①be sorry for (sth); ②be sorry for (doing sth); ③be sorry to (do); ④be sorry that+从句。如:I am very sorry for keeping you waiting so long.(不好意思让你久等了)I am sorry to trouble you.(对不起,麻烦你了)/ I am sorry (that) he isn’t here at the moment.(恐怕他现在不在)
(5) be sure (确信)的用法:记住几个结构: ①be sure of (sth); ②be sure to(do); ③be sure that+从句。如:She told me many times that she was sure to come.(她给我讲过多次她一定会来的) / Are you sure of your answer?Maybe it’s wrong.(你对你的答案有把握吗?也许是错的。)/ I am sure that Dad will help me with the job.(我确信爸爸会帮着我做这件事情的)
(6) make 与do的用法:一般情况下表示进行活动或者做工作用do,表示创造建构某事物用make. 如:I don’t know what to do.(我不知道该干什么)/ I’m not going to do any work.(我不准备做什么)/ My father and I once made a boat.(我和我爸曾经做过一只船)
此外还要记住一些固定说法:do good / harm / business / one’s best / a favour……
make a decision / an effort / a mistake / a noise / a phone call / money / war / the bed / sure,...
(7)put on、wear、have…on、be in、try on、dress的用法:put on强调“穿、戴”这个动作过程,wear则表示“穿着、戴着”这一状态,have+衣物+on主要表示状态,be in(+颜色/衣物)也是表示一个状况,dress(+人)表示“给…人穿衣”。如:Please put on your new shoes.(请穿上你的新鞋)/ The twins are wearing the same clothes.(双胞胎穿着相同的衣服)/ Today she has an overcoat on.(今天她穿着一件大衣) / Do you know the woman who is in black?(你认识那个身穿黑衣的女人吗?)/ Dad is dressing Tom now.(爹正在给汤姆穿衣)
[注意]dress与wear或put on的区别:wear或put on常用衣物作宾语,而dress常用人作宾语。表示给自己穿衣时常用“get dressed”或“dress oneself”表达。be dressed in与wear基本同义。dress up意为“穿上盛装、乔装打扮”。如:Could you dress the baby for me?(你能替我给宝宝穿衣吗?)/ He is eight but can’t dress himself.(他八岁了,还不会穿衣服)/ She was dressed in a red coat.(她穿着一件红上衣)/ Do I have to dress up to go to Jim’s party?(我得穿上好衣服去参加吉姆的聚会吗?)
(8)look for、search…for、find、find out的用法:前面两个词语表示动作过程,后面两个表示结果,look for指“寻找”不见的或丢失的东西,但还没有找到;search…for…指“为找…而搜寻…”;find指“找到”了东西;find out主要指“查明一个事实真相”。如:Hey, Monkey, what are you looking for in the cupboard?(嘿,猴儿!你在厨子里面找什么呢?)/ Have you found the lost key to your car?(你找着丢失的车钥匙了吗?)/ The soldiers were searching the room for the spy when they heard a loud noise.(士兵们正在房间里面搜寻间谍突然间他们听到了衣声巨响)/ Let’s try to find out who broke the window.(让我们查查谁把窗子打破了)
[注解] find的几个结构:find sb. sth“为某人找到…”,find sth./sb. + adj./n.“发觉某人是…”,find it +adj. + to do…(或+宾语从句)“发现(做……)如何”。如: His mother found her daughter a very clever girl.(他的母亲发现她的女儿是个聪明的女孩)(名词作补语补足语) / You can easily find it not good for your health to eat cold food.(你很容易就会发现吃冷食对你的身体是不利的)
(9)look、see、watch、read的用法:四个词均与眼睛有关,look指放眼去“看”(不管是否看得到),指“看”的过程;see指“看见”这一结果,有时see还引申为“明白”,表示“看”时后面加“电影”等词;watch指专注的看,含有“注视、监视”之义,后面常跟“电视、比赛”等词;read限制为看书面材料,译为“看、阅读”,后面跟“书、报纸、杂志”等词。如:What are you looking at?(你在看什么?)/ Please look at the blackboard. (请看黑板)/ Let me go to see the film, mum, will you? (妈妈,让我去看电影吧,好吗?)/ He won’t feel well until he finishes watching the football match. (要看完了足球赛他才会感觉好些)/ Reading gives us knowledge.(阅读给我们知识)
(10)hear、hear of、hear from、learn的用法: hear“听说”,后面可以跟名词、代词、从句表示听见的内容,hear of“听说”,后面跟人,指对某人有耳闻但没有见过面;hear from“收到……的来信”,后面加人;learn“听说、得知”,后面跟从句,含义与hear相似。如:I hear Mr Green is coming to see us tonight. (我听说格林先生今晚要来看望我们)/ Have you ever heard of the man who once went to the Himalaya Mountains? (你是否听说过那个去过喜马拉雅山的人?)/ How often do you hear from your father? (隔多久你收到你父亲的信?)/ He learned the musician himself was in town.(他听说音乐家本人就在城里)
(11)speak、talk、say、tell的用法:四个词与“说”有关。speak“讲话、发言、演说”,是不及物动词,涉及人时要加介词to,speak作及物动词时后面跟语言名称;talk“谈话、闲谈”,是不及物动词,涉及人时用介词with、to等,涉及事情时后面跟介词about等;say 是及物动词,后面跟名词、代词、从句等,表示说的内容;tell是及物动词,后面首先要跟人,然后再跟从句或者介词短语等。如:Do you speak English? (你讲英语吗?)/ Who spoke at the meeting? (谁在会上发了言?)/ Our teacher is talking to Lin Tao’s parent. (我们的老师正在跟林涛的家长讲话)/ Can you say it in English? (你能用英语说出它吗?)/ Please tell me something about the strange flying object. (请跟我讲讲那个奇怪的飞行物的事情吧)
(12)there be、have的用法:两个词都可以译为“有”,但是,have表示的是“拥有”,主语必须是人或者物;there be表示“存在”的概念,主语在there be之后。如:How many brothers and sisters do you have? I have only one brother. (你有多少兄弟?我只有一个兄弟。)/ How many chairs and desks are there in their classroom? There is none. (他们教室里有多少张桌椅?一张也没有。)
[注解]there be sb./sth doing与there be sb./sth to do 有所不同:用doing表示一个正在发生的事情,而用to do 则表示一个滞后或迟于there be的动作。如: Look! There is a dog lying on the stairway. / Take your time. There is nothing for you to do tonight.
(13)borrow、lend、keep的用法:表示“借”的三个词,borrow“借进”、lend“出借”都是一次性动作,不可以和表示一段的时间状语连用;keep“保存”用来表示借一段时间。如: I have lost the book I borrowed from my teacher. What can I do? (我丢掉了从老师那里借来的书)/ How long have you kept my dictionary,eh?For more than two months! (呃,我的字典你借了多久了?两个多月了!)
(14)bring、take、carry、send、lift的用法:bring指从远处“拿来”;take指从面前“拿走”;carry指一般的搬运,不涉及方向;send主要指“送、派遣、寄”;lift指把东西由低向高“提起、拎起”。例略。
(15)hope、wish的用法:两个词都表示“希望”,但是,hope表达有把握或信心实现的事情,后面直接跟动词不定式或者宾语从句,不可以跟动名词或作宾语补足语的不定式;wish表达实现的可能性不大的事情,后面跟名词、宾语从句(用过去时)或者作宾语补足语的不定式。如:We all hope to see him very soon. (我们全都希望尽快见到他)/ I hope it will be fine tomorrow so that we can go out. (我希望明天天好,这样我们就能出去了。)/ How I wish it was not raining at the moment!(我多么希望此刻不在下雨!)(事实上天正在下雨)

(17)arrive in/at、reach、get to的用法:arrive是不及物动词,到达具体地点时后面加介词at,到达一个大的地方(国家、城市)时后面加介词in,arrive后面可以直接跟地点副词here/there/home等;get表示“到达”时是不及物动词,涉及地点(无论大小)时后面加to,get后面可以直接跟地点副词here等;reach是及物动词,后面直接跟地点名词。如:He arrived in San Francisco last Sunday. (上个星期天他抵达旧金山)/ How did you get there in the night? (你是怎样在夜间到达那里的?)/ We hurried all the way and reached the station just five minutes before the train left. (我们一路狂奔在火车启动前5分钟到达车站)
(18)be made of、be made from、be made into、be made in、be made by、be made for的区别:be made of指从制成品中可以看得出原材料,而be made from则指从制成品中看不出原材料,口语中都可以换成be made out of。 be made into表示“被制成……”,be made in表达被制造的地点,be made by表达制造的人,be made for表达被制造的目的。如:This kind of paper is made from bamboo.

而lose则表示“输了”,常用句型:lose sth. to sb. 如:Unluckily we lost the match to Class Three. (不幸的是我们比赛输给了三班)
