动词词义辨析
动词是是各类考试的重点，高考试题中，单项填空、完形填空和改错等三项题型中，动词辨义的比重较大，并逐年增加。动词辨义主要指：1、形状相同的动词之间辨义。如：lie, lay; hanged, hung; rise, raise; sit, seat等。2、意义相近的动词之间辨义。如：borrow, lend; speak, say, talk; hope, wish等。3、动词与其它词形相近、意义相似的词的辨义。如：advise, advice; cost, worth; pass, past 等。4、意义不同，但容易混淆的动词的辨义。如：explain, say; discover, invent, uncover; find, find out等。5、某些常用动词的习惯用法的辨义。如：ask, give, call, make, find, get, keep, want, see, hear等。6、某些常用动词短语的辨义。如：give in, give up, turn on, turn off, turn down, turn up 等。
（一）易混动词
1、lay（放）, lie（躺）与lie（说谎）：这三个易混
rose，过去分词是risen，而raise是及物动词，是规则动词。
3、hear与listen to：hear侧重点是听到，听见什么，而listen to是侧重于听的倾向，但hear用于无意中的听见，而listen to却用于集中注意力的听。
4、see, watch和look：see用作看电影，剧目；watch 则用作看电视比赛，而watch还有在旁观看之意。如：Are you going to play or only watch?；look一般用作不及物动词，只是当盯着某人看时用作及物动词，如：The little boy looked me in the face.（小男孩直盯着我的脸。）
5、wind和wound：wind意为蜿蜒而行，其过去式与过去分词都是wound，而动词原形wound意为伤害，其过去式、过去分词都是wounded。
6、hang的用法：hang有两个意思：一为悬挂，是不规则动词，过去式、过去分词都是hung；二为绞刑，是规则动词，其过去式、过去分词都是hanged。
7、hear的过去分词born与borne：bear作为出生讲有两个过去分词born，borne。只有当be+born…
进行时态。put on是动作，但dress既可用作状态，又可用作穿衣动作，但用作状态时要用其过去分词作形容词如:He was dressed in a b1ue suit作动作讲时，其后不要接衣物而要接反身代词或表示人、物的名词，如：I dress my children in the morning every day.
20、begin与start
begin与Start 均可作开始讲，并无多少区别，同样可接不定式或动名词，但在下面的场合多要用Start：1)机器的开动发动；2)旅途的开始。如:we shou1d have to start early because there was a lot traffic in the street。
21、allow 与permit
allow与permit其后直接接动作时要用动名词，如接人后再接动词则要用不定式，所以用在被动语态时一定要用不定式。如：People are not allowed to spit.
22、find与found
find找到的过去式和过去分词都是found，而found 是动词“建立”的原形，其过去式和过去分词是founded，founded，如：The People’s Republic of China was founded in 1949.
23、speak, say, talk 与tell
英文中讲有4个词，speak, say, talk, tell，但其中speak, talk多用作不及物动词，但speak后加语言名词时则用作及物动词，如：Please speak English。而say与tell是及物动词，其中tell常用作接双宾语，如：Tell me a story。但也有些特定的习惯用法，如：在作讲实话，讲谎言，表示时间常用单宾语而不能换其它词，如：My watch was broken. It couldn’t tell time correctly。在书信、便条、海报上写着英文应为It said …。在作辨别不同讲时是tell，如：Can you tell me the difference between the two？而讲别人好坏话时用speak，如：The father always speaks well of his son.。
24、excuse me 与sorry
excuse me用于来打拢对方前以提醒对方注意的提示语，而sorry则表达因作了某事向对方道歉。
25、care for 与care to do
care for其后要接不定式时则要省去for或换用名词，如：Would you care for a cup of tea？但care for 作照顾讲时与look after相同。
26、与名词易混的动词有：advise(v.), advice (n.); accept(v.), except(prep.); pass(v.), past(prep.); bathe(v.), bath(n.); breathe(v.), breath(n.); choose(v.), choice(n.); succeed(v.), success(n.);
27、意义相近的动词：ring摇铃，打铃，电话铃响，strike专指敲钟，打几点，撞击；suggest提出实验性或推测性的建议，advice表示对经验不足人的一种忠告；look由视觉得出的印象，seem暗示一定根据的判定，appear外表印象而实际或结果并非如此；stay
停留，逗留，remain遗物，某物被取走一部分后剩余部分；discover（发现）找到早已存在但未被人所了解的东西，invent（发明）研制出不存在的东西；remember记忆起以前经历或知道的事，remind提醒某人做某事。
28、动词+ 副词+ 介词：catch up with, look forward to, come up with, keep up with, go in for, look down on, get on with …
29、动词+ 介词to的词组有：come to, stick to, object to, agree to, turn to, attend to, belong to, devote to, reply to …
30、与in相结合的动词有：give in, hand in, bring in, drop in, succeed in, take in, check in, engage in, fill in, trade in …
（二）动词短语
动词短语是指动词和介词、副词或名词的习惯搭配。有关动词短语的测试点主要涉及结构上选用恰当的搭配词，不同搭配含意上的辨异及不同短语的辨异。需掌握以下要点：
1、根据动词短语的不同特点，掌握其运用规律。
(I)动词+副词(不及物)
Harry turned up after the party when everyone had left. 晚会后，人们都已离去，哈里出现了。
(2)动词+副词(及物)
Please turn every light in the house off. 请把房子里的每一盏灯都关掉。
注意：①如果宾语较长，就应避免把副词同动词分开。如：She turned off all the lights which had been left on. 她关掉了所有还在亮着的灯。②如果宾语是人称代词，只能放在动词和副词之间。如：She gave them away. 她送掉了它们。
(3)动词+介词(及物)
I'm looking for my glasses. 我在找我的眼镜。
注意：①当它跟宾语时，不能把介词放在宾语后面。
②动词短语可以放在句子或从句末尾。如：She's got more work than she can cope with. 她的工作多得使她应付不了。
(4)动词+副词+介词
I look forward to seeing you soon. 我盼望不久就见到你。
注：“动词+介词”、“动词+名词+副词”、“动词+副词+介词”，这三种搭配都是及物的，如变成被动语态，不可漏掉介词。In this way both grain and vegetable can be well looked after. (不能漏掉after) 这样一来，粮食和蔬菜都能兼顾了。
2、熟悉同一动词和不同介词或副词、不同的动词和同一介词或同一副词搭配在意义上的差异。
(1)同一动词和不同介词搭配时，意义上的差异。如：①hear from收到…的来信，hear of听说。②look after照料，look at看，look for寻找。
(2)同一动词和不同副词搭配时，意义上的差异。如：①ring back回电话, ring off挂断电话, ring up打电话②put away放好, put on穿，上演, put up挂起，举起。
(3)不同动词和同一介词搭配时，在意义上的差异。如：look for寻找, call for去取(某物)，去接(某人), ask for请求, wait for等候, send for派人去叫。
(4)不同动词和同一副词搭配时，在意义上的差异。如：①break out发生，爆炸, carry out进行，开展, go out熄灭, hand out分发, let out放出, look out当心, sell out卖完, set out出发, take out取出, work out算出。②break down出毛病, come down落下来, get down下车, take down取下, write down写下。

高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 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. 情态助动词的特征 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

最新英语语法情态动词归纳总结 一、单项选择情态动词 1．Mr. Smith is almost on time for everything. How ________ it be that he was late for the meeting? A．can B．should C．may D．must 【答案】A 【解析】 【详解】 考查情态动词辨析。句意：史密斯先生几乎任何事情都是准时的。他怎么可能开会迟到了？ A. can可能，可能性，表示可能性时，常用于否定句和疑问句中，且有时还带有“惊奇、不相信” 等感情色彩。B. should 应该； C. may也许，表示可能性时常用于肯定句中，不用于疑问句中。D.must常用于肯定句中表推测，“一定……”的意思；本题是强调句型的一个变式：强调其特殊疑问句how的形式。根据前句“斯密斯先生几乎是很准时”可推测出“怎么可能开会迟到呢？”。根据句意可知，用于疑问句中的“可能性”且有不相信的色彩，四个选项只有“can”符合题意。故选A 【点睛】 情态动词就是表示说话者对事情的一种看法，也就是一种语气。情态动词的用法一直是命题者常设置的考点和重点，平时要加强记忆。 2．--- Oh, my God! I just missed the last bus back home. --- That’s really bad. I’m sure you ______ it, but you just didn’t hurry up. A．had caught B．could have caught C．could catch D．can catch 【答案】B 【解析】 【详解】 考查情态动词+have done结构。句意：——哦,我的上帝!我刚好错过了回家的末班车。——这是非常糟糕的。我肯定你能赶上，但你就是不抓紧。could have done“本来能做而没有做”。故选B。 3．-- Did Jim come? -- I don’t know.

高中英语语法之情态动词 （一）情态动词的定义：情态动词表示说话人对某一动作或状态的态度。 （二）情态动词的特点：1）有一定词义；2）不受主语人称和数的变化影响；3）与主要动词 的原形（或称不带to的不定式）一起构成谓语（除ought to作固定词组看待）。 情态动词无人称和数的变化, 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。 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. I asked if he would come and repair my television set. 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. （三）情态动词有四类：①只做情态动词：must,can(could),may(might),ought to ②可做情态动词又可做实义动词：need,dare ③可做情态动词又可做助动词：shall(should),will(would) ④具有情态动词特征：have(had,has) to,used to ⑤情态动词表猜测 （四）情态动词的基本用法 1. can (could) 1）表示能力，could主要指过去时间。 Two eyes can see more than one. 两只眼比一只眼看得清。 Could the girl read before she went to school? 这女孩上学前能识字吗？ 2）表示可能（理论上或是逻辑判断上）。 The temperature can fall to –60℃, that is 60℃ below freezing. 气温可降至—60℃，也就是零下60℃。 t) have enough money for a new car. 他不可能有足够的钱买新车。 He can′ t (couldn′ re walking around in the wood. You could start a fire. You mustn′ t smoke while you′
