start在许多场合可与begin通用，但start侧重动作的起点。
commence可与begin换用，但commence系书面正式用词，语气庄重，特指有正式程序或一定仪式，或某种正式行动的“开始”。
initiate指创始或发起，侧重某过程的第一步，不考虑结束，强调起始。 inaugurate指正式而隆重的开始。三、词义辨析：depart,leave,go,start,quit,set out这些动词均含“离开某处”之意。 depart较正式用词，指经过周密考虑或郑重地离开，强调离开的起点。 leave侧重出发地而不是目的地。
go一般用词，指从所在地到其它地方去，着重目的地而非出发地。 start可与leave换用，强调目的地，但不及leave普通。
quit侧重指离开令人烦恼的地方，或摆脱使人不快的人或事。 set out书面用词。四、相关短语：at the start开始时from start to finishadv.自始至终housing start住房工程,安居工程kick start摩托车start outv.出发,动身start upv.突然站起,突然出现,发动,开动flying startn. 快速起跑，快速起动 迅速起步，迅速发展head startn. 领先running start良好的开端一、参考例句：Start small.从小事开始吧。Start early.尽快开始。Let' s start afresh.我们重新开始吧。Start a telephone conversation.开始一个电话对话。Start on Johnson Road.从约翰逊路出发。Let's start cooking.我们开始做饭吧。Prices start at $ 5.从五美元起价。Start your life handbook.写本“人生手册”。Start keeping a journal.开始写日志。Start a journal.开始写日记。近义词辨析—start和begin在用法上面的区别start和begin在用法上面的区别单词 start 和 begin 都是使用频率很高的基础词汇。它们都有“开始”的意思，而且在英语中常被当成近义词甚至是同义词使用。可以说，掌握
start 和 begin 的用法是英语初学者的必修课。一、我们先来复习一下它们的共同点。首先，这两个词都包含“开始”的意思，先来听两个例句。Shall westart?Shall we begin?在以上的两个例句中，“shall we start”和“shall we
begin”都是“我们可以开始了吗?”的意思，没有本质上的区别。在这里，start 和 begin 都是不及物动词。start 和 begin 的后面都可以接不定式“to do”或动名词“doing”，意思是“开始、着手做某事”。请看两个例句：I got the job and I begin towork on Monday! 我得到了这份工作，将在周一开始上班。She started to feel dizzy soon afterthe accident. 事故发生后不久，他就感到头晕。二、虽然，start 和 begin 在很多情况下含义相似，但在日常生活中，start 的使用频率更高, 更随意，也较为口语化。单词 start
有一些 begin
不具备的用法。例如,“start”的意思是“创立公司、企业、机构、发动汽车、机器等”。在表达这层意思时，我们不能用“begin”与之替换。Sammy started his own company at 16 years old.赛妮在她16岁时就开始创办了自己的公司。Richard returned to his hometown and started his own business.理查德回到了家乡，开始了自己的事业。Li Mei couldn't start the car. 李梅发动不了那辆汽车。Some modern cars allow you to start the engine without using a key.一些现代化的汽车已经可以不用钥匙便发动汽车了。此外,“start a family 组建家庭”指“生第一个孩子”。Recently,Mary and I have been thinking about starting a family.最近，玛丽和我开始考虑组建一个家庭。start 后面还可以接不同的介词，比如“start over 重做、重新开始”等等。Don’t talk to me when I’m counting. Now I have to start all over again.当我在数钱的时候不要跟我说话。现在我不得不重新数一遍。三、begin的用法和start不同。begin有从头开始的意思，而start是从哪儿开始(不一定是起点，半截也行)都行。Let us begin
our show! 让我们开始节目吧!(在这里节目是从头开始。)四、如果我们想说“从头开始”，那我们既可以用start也可以使用begin，但用法略有不同1)使用start：Start from the beginning (这里要加from the beginning 来强调”从头开始“里的“从头”)
2)使用begin：Begin from here (在这里不用加“from thebeginning”因为begin含有从头的意思)五、start 的名词形式也是 start，而 begin 的名词形式是 beginning。We were late, so we missed the beginning of the movie.因为我们来晚了，所以我们错过了这部电影开始的部分。he school has courses for beginning [=elementary], intermediate, and
advanced students.这所学校为学生准备了初级课程、中级课程和高级课程。名词“beginner”指“初学者、新手”。来听几个例句。This is a swimming classfor complete beginners( =a beginner class).这是一个为初学者准备的游泳课。I am not a very good driver. I am just a beginner.我不是一个有经验的司机。我现在还是一个新手。start的用法和短语例句start的用法：start的用法1：start的基本意思是“从静止状态转移到运动状态”,可指工作、活动等的开始; 战争、火灾等的发生;
也可指人开始工作,着手某项活动等; 还可指人、事物使某事情发生或引起某事情。start的用法2：start可用作不及物动词,也可用作及物动词。用作及物动词时,可接名词、代词、动名词、动词不定式作宾语,也可接以现在分词充当补足语的复合宾语。start偶尔还可用作系动词,接形容词作表语。start的用法3：start可用一般现在时或现在进行时来表示将来。start的用法4：start后可接动名词或动词不定式。接动名词时常表示动作将持续下去,接动词不定式时常表示动作的开始。start的用法5：start用作可数名词的基本意思是“开始,出发,起点”,可指做某件事情的开始,也可指某件事情的开始地点,是可数名词。start的用法6：start也可用于表示某件事开始时就有“领先地位,有利条件”,通常用作不可数名词,但可用不定冠词a修饰。start的用法7：start还可作“惊动,惊起”解,一般为可数名词,经常用单数形式,与不定冠词a连用start的常用短语：用作动词 (v.)start back (v.+adv.)start for (v.+prep.)start in (v.+adv.)start off (v.+adv.)start out (v.+adv.)start out of (v.+adv.+prep.)start over (v.+adv.)start somethingstart up (v.+adv.)用作名词 (n.)for a startfrom start to finishget off to a good〔bad〕, etc. startmake a fresh startstart的用法例句：1. there has been a busy start to polling in today's local elections.今天地方选举的投票一开始就人头攒动。2. try these toning exercises before you start the day.在开始一天的活动之前，试着做做这些强身健体的体操。3. i saw through your little ruse from the start.从一开始我就看穿了你的小计谋。4. it's just not enough money to start life over.这些钱根本不够用来开始全新的生活。5. the horse made a winning start for his new trainer.这匹马为它的新驯马师开了个好头。6. thousands and thousands of start-up firms have poured into the computer

高中英语动词的时态和语态专题训练题【网络构建】动词时态与语态是两个非常重要的语法范畴，构成了英语语法的基本框架。因此时态与语态也是高考中出现频率最高的语法项目。英语有十六种时态，但常考的主要有一般现在时、一般将来时、一般过去时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时及完成进行时等。语态一般不单独设题，通常结合时态进行综合考查。（一）时态概念时态是谓语动词所表示的动作或情况发生的时间的各种形式。英语中有十六种动词时态形式，但常见的有九种，见下表：时态名称 表示时间 表达的意义 例 句一般现在时现在 习惯于或经常性动作 Class begins at eight every morning .状况 He looks very pale .瞬间动作 There comes the school bus .过去 描述过去的事实，以求描述的生动性 The river rises higher and higher , breaks the banks and fills all low places .将来 固定不变或不易变的动作或状态 Tomorrow is Sunday .（在时间或条件从句中）表示将来的动作或状态 When he arrives ,we’ll go out to meet him .It will be 3 hours before I come back .不受时间限制的动作或状态 The sun rises in the east .Practice makes perfect.一般过去时过去 某时（或某段时间内）的动作 He traveled in France last year.状态 He was in Shenzheng some years ago .习惯动作 When I was at college , I wrote home once a month.先后一连串动作 He went to town ,bought some books and visited his daughter.现在或将来 非真实的动作或状态，属虚拟语气范畴 It’s time we had supper.If he arrived tomorrow , I should meet him at the airport.一般将来时将来 某个时刻（或某段时间内）将要发生的动作，更多地用于带有条件从句的主句中 He will come next week . I’ll ask her as soon as she comes.状态 Your dress will be ready soon.现在 预测现在某事可能要发生了 It’s ten o’clock . Mary will be in bed by now.现在的习惯 A lion will never attack an elephant .现在的需要 Shall I help you ?对将来的事情现在作出决定 ---Which shirt do you want ?---I’ll take the red one, please.现在进行时现在 某时（或某段时间内）正在进行的动作 He is writing a letter now. She is visiting Shanghai this week .婉转口气 I’m hoping to hear from you soon.带有感情色彩的叙述 The boy is always talking in class.将来 按计划一般不易变更的动作 The train is leaving at 11:00 p.m..（在时间或条件从句中）表示将来的动作 When you are cycling along the street , don’t’ forget the traffic light.过去进行时过去 某时（或时间段内）进行的动作 I was doing my homework this time last night.故事发生的背景 The wind was blowing and it was raining hard.带有感情色彩的叙述 He was making trouble all the time .过去说话前不久的动作 I was telling him his mother was ill .婉转口气 I was hoping you could help me.过去将来时过去 间接引用某人过去的话和想法 He warned us that the journey would be dangerous .习惯性动作 At dusk , these old ladies would sit in rocking chairs and talk.现在 非真实的动作或状态 If I were you , I would study French .客气的请求 Would you mind helping me ?愿望 I would like a cup of tea.现在完成时完成用法 现在时间前完成的动作留下的结果或影响 He has turned off the light .I have been to Japan .现在时间前已做的动作 He is reading the book that he has bought recently .（在时间或条件从句中）表示在将来某个时间前先要做完的动作 I’ll return the book to you as soon as I have finished it .未完成用法直到现在为止尚未完成的动作 He has lived in Wuhan since last summer.过去完成时 完成用法 过去某一时刻或某一事件前完成的动作或状态 By the end of last term we had learned 3000 English words.未完成用法 过去某一时刻或某一事件前已发生但未完成的动作 By December last year , he had worked in Beijing for five years .其他用法表示非真实的,想象的过去动作或状态 I wish I had told him about it . If she had worked harder , she would have succeeded.They had meant to see me off at the airport , but they got there too late.（二） 时态的运用1．现在时等表示将来时【重点提示】 用现在时表示将来时往往出现在以下状语从句中：if , unless , even if 等引导的条件状语从句；when , before ; after ; once ; until ; till ; as soon as ; (the moment ;immediately )等引导的时间状语从句；no matter what/ who/ which/ when/ where/ how 或whatever/ whoever/ whenever/ wherever/ however/ whichever引导的让步状语从句。在上述从句中如果主句是将来时（往往出现will , shall , can , must 等情态动词或祈使句），从句用一般现在时表示一般将来时。如：I’ll not go to his birthday party unless I’m invited.Tell him the news as soon as he comes back .有时这个时态表示按计划、规定要发生的动作（句中带有时间状语），但限于少数动词如begin , come , leave, go arrive , start , stop , return , open , close等。如：The meeting begins at seven .The train starts at nine in the morning .当主句是过去将来时，用一般过去时表示过去将来时。如：He said he would go for a holiday when he finished his work.上述从句中还用现在完成时表示将来完成时，此时强调从句动作在主句之前发生。如：You can’t go out until you have finished your homework .(先完成作业再出去玩。)2．过去时在语境中的运用【重点提示】在没有明确时间状语的情况下，考生对过去时的判定往往会失误，原因是只凭汉语直译而不看语境。语境中的过去时往往表示“刚才、刚刚”之意，暗示现在已“不再这样”。如：I never thought he would do that .3.现在完成时与一般过去时【重点提示】考生很容易将现在完成时误用为一般过去时，原因是没有深刻领会“现在完成时强调对现在造成的影响”这句话的含义。一般过去时仅仅说明动作在过去，不强调对现在的影响。如：---Where have you put the recorder? I can’t find it anywhere!---I put it right here , but now it’s gone .问句用现在完成时，表明说话者在找录音机，希望对方告诉他录音机在哪里。而答语用过去时，因为“录音机已经不见了”。“刚才”把录音机放这儿与“现在不见了”没有直接关系。4．某些固定的句式中的时态【重点提示】在某些固定的句式中，其时态是固定的、约定俗成的。1） This / It is / will be the first / second ---time +that 从句一般用现在完成时，若主句be动词用was ,则that 从句用过去完成时。如：This is the first time I have come here.It was the third time (that) he had made the same mistake.2） It is / has been + 一段时间+since 从句。Since 从句中一般用过去时，如果将前边的is 改成was ，则since 从句中用过去完成时。如：It was ten years since we had had such a wonderful time .3) be about to do ---when ---意为“即将------（这时）突然------”。如：I was about to go to bed when the telephone rang.4) be (was / were ) doing--- when ---意为“正在干------（这时）突然------”。如：They were playing football when Jack shouted in pain .5) Hardly had ---done ---when--- ; No sooner had --- done ---than---when 和than 从句里也用过去时，表示“刚刚------就------”。如：Hardly had I got home when the rain poured down .No sooner had the villagers left the burning building than it fell down into pieces .6) It + be +一段时间+before 从句该句式分两种情况：若主句用将来时，则从句用一般现在时表将来时，意为多长时间以后即将发生某事；若主句用过去时，从句也用过去时，意为多长时间后发生了某事。如：It wont’ be long before he succeeds.(=He will soon succeed.)It was ten years before they met again .(=They met again ten years later.)5.现在完成进行时【重点提示】 现在完成进行时主要表示动作开始于过去某时，一直持续到现在，当然中间动作有时并非无停顿。事实上现在完成进行时除了表示动作“已完成”的概念外，也可以表示动作“未完成”概念，一般可换用，但口语中更倾向于用现在完成进行时。如：He has taught English for 10 years.也可说成: He has been teaching English for 10 years .下列最好用现在完成进行时，因为带有一定的感情色彩。如：Where have you been ? I’ve been telephoning you the whole morning !He’s been talking to me since this morning .6.非延续性（终止性）动词怎样表示一段时间【重点提示】 非延续性动词有mary , die , close , arrive , post , come , fall , leave, go , break , give , join , jump , receive, buy , borrow , become , start , begin , graduate等。这些非延续性动词如果用于现在完成时，不能与表示一段时间的时间状语for ---, since ---连用。如：可以说：I have bought an Audi car.不可以说：I have bought an Audi car for a year.如果要表示一段时间，句中不能用终止性动词，一定要用相应的延续性动词。如：I have had an Audi car for a year.也可以用以下方式：I bought an Audi car a year ago .It’s / has been a year since I bought an Audi car.二、 语态当句子的主语是动作的承受者时，谓语要用被动语态。被动语态由be动词+动词过去分词构成，时态通过be 的变化形式来体现。如：The bridge is being built now .He was asked a lot of questions at the meeting .动词say , believe , report , announce , suppose ,know ,consider ,hope 等以it 作主语时用被动语态，后面接that 从句。如：It is said that our football team has won the game .【重点提示】　英语中有时用主动形式表示被动含义，主要有以下三种情况：谓语动词、非谓语动词和介词短语。(一) 用谓语动词的形式表示被动含义1． 表示状态特征的连系动词look , sound , feel ,smell , taste , prove, appear+形容词/ 名词构成的系表结构。The steel feels cold.His plan proved (to be )practical .2.表示“开始”、“结束”、“运动”的动词，如begin , finish , start , open , close , stop , end , shut , run, move.Work began at 7 o’clock this morning .The shop closes at 6 p.m. every day .3.表示主语的某种属性特征的动词，如read, write ,act , sell , wash , clean ,open , cook,lock ,shut ,dry ,eat , drink.这类动词一般不单独使用，常加上一个修饰语。如：This coat dries easily .The pen writes smoothly.4.少数动词用于进行时，其主动形式表示被动含义。如 ：print , build , cook , fry , hang ,make .The books are printing .（二）用非谓语动词的主动形式表示被动含义1. want , need , require 作“需要”讲时，后用动名词的主动形式表被动含义，这时动名词同句子的主语之间在逻辑上有动宾关系。如：The house needs / wants / requires repairing .2. 形容词worth 后用动名词的主动形式表示被动含义This problem is well worth considering .The close game is worth watching .3. 不定式在某些形容词（difficult ,easy ,hard ,comfortable , pleasant , fit ,unfit , light , heavy ,good , safe ,dangerous ）后作状语且和句子的主语（或宾语）构成逻辑上的动宾关系时，用主动形式表示被动含义，这是因为人们往往认为形容词后省去了for sb. 如：The question is difficult (for me )to understand .She is easy (for people )to get along with .4. 不定式作名词的后置定语，与被修饰的名词构成逻辑上的动宾关系，又和该句的主语后宾语构成逻辑上的主谓关系时，不定式常用主动式表被动含义。如：I have a lot of work to do this evening .5. 在there be 句型中修饰主语的动词不定式用主动形式和被动形式皆可。在口语中多用主动形式。如：There are many things to do / be done .6. 不定式to let , to blame 等表示被动意义。如：The car is to let. (汽车出租。)（三） 介词in , on , under 等+n. 构成的介词短语表示被动意义The house facing the lake is in the possession of John.=The house facing the lake is possessed by John.The question is under discussion .=The question is being discussed .【命题趋势】历年来高考中时态题一般要求考生能够根据上下文捕捉和体会动作发生的时间信息，充分注意题干中语境，准确判断时态，弄清句子主语和谓语之间的主动关系和被动关系；熟练掌握英语动词的各种时态，并侧重区别一般过去时与现在完成时、一般过去时与过去完成时的用法。一般来说考进行时和完成时的频率更高一点。语态一般很少单独设题，往往穿插在时态中进行综合考查，要求考生掌握各种时态的被动形式尤其是现在进行时的被动语态和过去完成时的被动语态。【点击真题】【例1】---Sorry to have interrupted you . Please go on .---Where was I ?--- You ____ you didn’t like your father’s job. (2004北京春)A. had said B. said C. were saying D. had been saying【答案】 C。【点拨】本题考查过去进行时与过去时及过去完成时的区别。【解析】本题是一组对话。第二句意为“我刚才讲到哪里了？”对方回答说“你刚才正讲到你不喜欢你父亲的工作那个地方。”应该指刚才正讲到------，所以用过去进行时，选C。【例2】 How can you possibly miss the news ?It ____ on TV all day long .has been B. had been C. was D. will be (2004北京春)【答案】A.【点拨】本题考查时态用法。【解析】从句意来看，“你怎么可能会没听到这个消息呢？电视上整天在播放该消息。” 而且句中all day long 表示该动作或状态一直在进行，因此应该用完成时态。【例3】All morning as she waited for the medical report from the doctor , her nervousness ___.A. has grown B. is growing C. grew D. had grown (NMET2003)【答案】C.【点拨】本题考查时态用法。【解析】 先排除A、B两项，因为从从句看，说的是过去的事，与现在无关；再排除D项，因为“她”不可能在等候医学报告之前就增加了紧张感了。故应选C表明“等候”与“增长”两个动作都在过去同时发生。【例4】At this time tomorrow ____ over the Atlantic .A. we’re going to fly B. we’ll be flying C. we’ll fly D. we’re to fly (2003北京)【答案】B。【点拨】本题考查将来进行时shall (will )be +现在分词的用法。【解析】shall (will )be +现在分词的用法可表示“纯粹的将来”，说话者仅陈述一个事实。或表示某种可能的推测，有“我料想，我估计”的含义。本题中的时间状语at this time tomorrow很明显是个将来进行时，故选B。【例5】---____ David and Vicky ____ married ?---For about three years.A. How long were; being B. How long have ; gotC. How long have ; been D. How long did ; get （2003北京）【答案】C.【点拨】本题考查1.延续性动词的用法.2.动词短语be married ,get married 的区别.【解析】 根据回答 “For about three years .”可知应提问两人结婚(到现在)已多久了,须用现在完成时,排除A、D两项；再排除B项，get married 当作非延续性动词使用，不能和表示一段时间的状语连用，不能用How long 来提问。Be married 表示延续的状态，是延续性动词。【例6】 The news came as no surprise to me .I ____ for some time that the factory was going to shut down . （2003北京）A. had known B. knew C. have known D. know【答案】A.【点拨】本题考查动词时态的用法知识。【解析】本题的第一句是关键“对于那消息我不感到惊讶”，原因就是在这之前已经知道了内容。第一句用了一般过去时，在一过去动作之前的事情，应选过去完成时。【例7】 I ____ ping-pang quite well , but I haven’t had time to play since the new year .A. will play B. have played C. played D. play (NMET2001)【答案】D。【点拨】该题考查动词时态。【解析】But 后的并列分句用在现在完成时的否定表示到现在为止未完成的动作，由此可推断出一个并列分句表示的是经常性的或习惯性的动作，须用一般现在时，故答案为D。【例8】 I arrived late ; I ____ the road to be so icy. (2004北京春)A. wouldn’t expect B. haven’t expectedC. hadn’t expected D. wasn’t expecting【答案】C。【点拨】本题考查的是时态用法。【解析】本题由两个分句组成。前一个分句用一般过去时。后一个分句中的动词expect 实际上是发生在前一个分句中动词arrived之前，指在此之前没有料到路面会那么的滑。因此应该用过去完成时。故答案选C。【例9】Selecting a mobile phone for personal use is no easy task because technology ___ so rapidly . (NMET2001)A. is changing B. had changed C. will have changed D. will change【答案】A.【点拨】本题考查动词的时态用法。【解析】题干为一个含有原因状语动句的主从复合句，主句陈述的情况是一客观事实，原因状语从句强调一直正在进行的动作，故答案为A。又如：Don’t turn off the light because I am reading a report now.【例10】Come and see me whenever _____.A. you are convenient B. you will be convenientB. it is convenient to you D. it will be convenient to you (2003北京)【答案】C。【点拨】本题考查1.whenever “任何时间”引导的时间状语从句2.convenient 一词的用法.【解析】 1.先排除B、D两项，因为状语从句中一般将来时需用一般现在时代替。2.convenient “方便的,合适的”,be convenient to sb.(对某人来说)如果方便的话.排除A 项.【拓展演练】【基础过关题】1.---You’re drinking too much .--- Only at home .No one ___ me but you .A. is seeing B. had seen C. saw D. sees2.---Look at the terrible situation I am in !
