7、the high way this morning. Three men were killed, the wounded were taken away to hospital at once and policemen were sent there to cope with the event.今天早晨高速公路上发生了一起车祸，三人丧生，伤员马上被送往了医院，并马上派了警察去处理这一事件。另外，在科技论文中，常使用被动语态来强调客观事实。如：When it is cold enough, water will be turned into ice.当天气足够冷时，水就会变成冰。So fa

8、r, the moon has been visited by earthmen several times.到目前为止，地球人已经几次拜访了月亮。并列连词eitheror用法归纳eitheror主要用于表示选择，其意为“要么要么”“或者或者”，用于连接两个性质相同的词或短语。如：You can have either this one or that one.你拿这个或那个都可以。You must either go at once or wait till tomorrow.你要么马上走，要么等到明天。We can finish the work either this week or n

9、ext week.不是这星期就是下星期我们就可完成这项工作。在具体使用not onlybut also时还应注意以下几点：1.eitheror连接两个成分作主语时，谓语动词通常与其靠近的主语保持一致。如：Either you or I am to go.你或我必须有人去。Either he or you are right.要么他对，要么你对。但在非正式文体中，有时也会一律用复数谓语。如：If either David or Janet come, they will want a drink.大卫或珍妮特来的话，是会要喝酒的。2.eitheror除可连接两个词或短语外，有时也可连接两个句子。

10、如：Either you must improve your work or I shall dismiss you.要么你改进工作，要么我就辞退你。Either youll leave this house or Ill call the police.你要是不离开这座房子，我就叫警察来。3.eitheror的否定式可以是not eitheror，也可以是neithernor.。如：He didnt either write or phone.=He neither wrote nor phoned.他既没写信又没打电话。注意，正如不能说eithernot一样(但可说noteither)，英

11、语习惯上也不说eitherornot，如不能说：Either he or his wife hasnt come.可改为：Neither he nor his wife has come.并列连词not onlybut also用法归纳not onlybut also表示“不仅而且”“既又”，用于连接两个性质相同的词或短语。如：Not only men but also women were chosen.不仅仅是男的，女的也有被选中的。We were not only hungry, but also tired.我们不但饿了，而且也累了。She likes not only music b

12、ut also sport.她不但喜欢音乐而且喜欢运动。She not only plays well, but also writes music.她不仅很会演奏，而且还会作曲。We go there not only in winter, but also in summer.我们不仅冬天去那儿，而且夏天也去。另外，在使用not onlybut also时还应注意以下几点：1.有时可将but also分开用，即将but视为普通的并列连词，用于连接两个句子，然后将also用于句中（用谓语动词用在一起）。如：Hes not only very fast, but hes also got ma

13、rvellous technique.他不仅很快，而且技术高超。2.该结构中的also有时可以省略，或将also换成too, as well（置于句末）。如：He not only washed the car, but polished it too as well.他不仅冲洗汽车，而且还擦拭了它。His name is known not only in Japan, but in China.他不仅在日本出名，而且在中国也出名。3.有时因为语境的需要，not onlybut also也可能用于连接两个性质不同的词或短语，但这多半因为承前省略的原因。如：He not only goes t

14、o work on weekdays, but also on weekends.他不仅工作日去上班，在周末也去上班。句中的not only后接的是谓语goes to，而but also后接的却是状语on weekends，可视为but also后承前省略了谓语动词goes to work。4.当not onlybut also连接两个主语时，谓语动词的数原则上与其相近的主语保持一致。如：Not only the students but also their teacher is enjoying the film.不仅学生们在欣赏这部影片，他们的老师也在欣赏这部影片。5.为了强调，可将no

15、t only置于句首，此时其后的句子通常要用部分倒装的形式。如：Not only has she been late three times, she has also done no work.她不仅仅迟到了3次，她还没干一点活。Not only do they need clothing, but they are also short of water.他们不但需要衣服，而且还缺水。有时也可见到不倒装的情形，此时主要见于but also后接省略结构的情况（省略只剩下主语）。如：Not only my mother was unhappy, but Marian, too.不仅我母亲不快乐

16、，玛丽安也不快乐。注意这些句子中的并列连词有这样一道题，该选哪个答案？注意与句中的并连词有关：They werent a particularly good team, but they refused to give in and_defeat.A. acceptB. acceptedC. acceptingD. to have accepted容易误选B，误认为accepted与谓语refused并列。其实，最佳答案为A，动词accept与give并列。请看类例：(1)Mother told Jim to watch the milk until it boiled and then_of

17、f the gas.A.turnB.turningC.turnedD.having turned答案为A，turn off the gas与watch the milk until it boiled并列。(2)He just does what he pleases and never_about anyone else.A.thinkB.thinksC.thinkingD.thought答案选B，thinks与前面的does为并列谓语，同用一般现在时。(3)I dont know whether to stay in teaching or_another job.A.trying get

18、tingB.to try to getC.trying to getD.try get答案选B，to stay in teaching与to try to get another job为两个并列的选择成分，故同用不定式。另外比较：try to do sth=设法做某事，try doing sth=做某事看看有何效果。连词because用法详解1.表示原因，语气较强，可用来回答why提出的问题。如：A：Why do you love her?你为什么爱她?B：Because she is kind.因为很善良。2.because除经常用于引导原因状语从句外，还可引出表语从句或用于强调句等。如：

19、It is because youre eating too much.那是因为你吃得太多了。It was because I wanted to buy a dictionary that I went to town yesterday.我昨天是由于想买本字典而进城的。3.汉语说“因为所以”，但英语却不能用becauseso这样的结构。如：因为我病了半年，所以把工作丢了。误：Because I was ill for six months, so I lost my job.正：Because I was ill for six months, I lost my job.正：I was

20、ill for six months, so I lost my job.4.汉语说“之所以是因为”，英语可以类似以下这样的句型（用that比用because普通）。如：The reason(why)Im late is thatbecauseI missed the bus.我迟到的原因是因为我没有赶上公共汽车。传统语法认为这类句型不能用because,但在现代英语中用because的情形已很普遍。5.在notbecause这一结构中，not有时否定主句，有时否定从句，具体视语境而定。一般说来，若not否定主句，最好在because之前用逗号，否则会引起歧义，如下句在没有特定上下文时就有两种

21、解释：I didnt go because I was afraid.这个句子既可理解为“我没有去是因为怕”，也可理解为“我不是因为怕才去”。但是，如果because之前有副词just修饰，一般认为not是否定从句而不是主句。如：You shouldnt get angry just because some people speak ill of you.你不要因为有人说你坏话而生气。6.有时可引导一个句子作主语，此时通常采用just because这样的形式，并且主句谓语动词通常（当然不是一定）为mean。如：Just because you speak English doesnt me

22、an you can teach it.你会说英语并不意味着你能教英语。Just because youre old doesnt mean you have to be idle.只是因为你年纪大了，这并不意味着你就应该懒散不活动。Because you have words with your wife is no reason to smash up things.你和你的妻子吵架并不能成为摔东西的理由。7.用于构成复合介词because of，其后可接名词、代词、动名词、what从句（但不能是that从句或没有引导词的从句）等。如：He is here because of you(t

23、hat).他为你（那事）而来这里。We said nothing about it, because of his wifes being there.因为他妻子在那儿，我们对此只字未提。He left the company because of what the boss said at the meeting.他离开了这家公司，是因为老板在会上讲的话。8.because of通常用来引导状语，而用于不引导表语（引导表语时可用due to）。如：误：His absence is because of the rain.正：His absence is due to the rain.他因雨

24、未来。但是，若主语是代词（不是名词），则它引出的短语也可用作表语。如：It is because of hard work.那是因为辛苦工作的原因。It will be because of money.那将都是因为钱的原因。although与though的同与异1.用作连词，表示“虽然”，两者大致同义，可换用，只是although比though更为正式。如：ThoughAlthoughtheyre expensive, people buy them.虽然它们很昂贵，人们还是买。2.although一般不用作副词，而though可用作副词，表示“可是”“不过”。如：I expect your

25、e rightIll ask him, though.我认为你说得对我去问问他也好。She promised to phone. I heard nothing, though.她答应要打电话来.可我没听到回信儿。这样用的though通常位于句末，但有时位于句首的though也有这样的意思。如：他说他要付钱，然而我认为他不会付的。正：He says hell pay, though I dont think he will.正：He says hell pay;I dont think he will, though.3.在as though（好像，仿佛），even though（即使，纵然）

26、等固定短语中，不能用although代替though。如：She treats me as though I were a stranger.她待我仿佛我是一个陌生人。Hes the best teacher even though he has the least experience.他尽管经验最少，但教得最好。4.两者均可用于省略句，通常见于主句与从句主语相同，且从句谓语含有动词be的情形。如：AlthoughThough(it was)built before the war, the engine is still in perfect order.尽管是战前制造的，这台发动机仍然处

27、于良好状态。AlthoughThough(he is)still young he is going very grey.尽管他还年轻他的头发却已变得灰白。AlthoughThough(she was)in pain, she bravely blinked back her tears.她虽然很疼痛，但还是硬把眼泪抑制住了。5.当though用于倒装形式，它不能换成although，但可换成as。Successful thoughashe is, he is not proud.他虽然成功，但不骄傲。Much thoughasI like you, I couldnt live with y

28、ou.我尽管很喜欢你,却不能和你在一起生活。Try thoughasI would, I could not make her change her mind.不管我多努力，也不能让她改变主意。Surrounded thoughaswe were by the enemy, we managed to march forward.虽然我们被敌人包围着，但我们还是设法前进了。Raining hard thoughasit is, Im going out for a walk.虽然正在下着大雨，我还是要出去散步。注意，若倒装后置于句首的是名词时，其前习惯上不用冠词或其他限定词。如：Expert

29、thoughashe was, he failed.他虽是专家，但还是失败了。Big puzzle thoughasit was, it hadnt got the better of Jim.虽然是个大难题，但仍没有难倒吉姆。6.不要按汉语“虽然但是”的表达习惯，在although后连用but。如：虽然他只是个业余爱好者，但却是一流的高手。误：Although hes only an amateur, but hes a first-class player.正：Although hes only an amateur, hes a first-class player.但是在强调时，alt

30、hough可与yet, still等副词连用。如：Though he seems happy, yet he is worried.虽然他看起来很幸福，但他实际上很烦恼。值得一提的是，在某些特定的语境中，although与but连用的句子是可能的（注：but引出的句子在although从句之前）。如：But I didnt know that then, although I learned it later.但我当时的确不知道此事，尽管后来还是知道了。He wanted to go abroad, but although he had some money he couldnt affor

31、d it.他想出国，尽管他有些钱，但还是负担不起。but与however有何区别两者均可表示转折或对比，意为“但是”“可是”“然而”等，但有区别：1.表示转折时，but是连词，用于连接词、短语或句子。如：He is young but very experienced.他虽年轻，但经验很丰富。2.however表示“然而”“可是”时，有的词书认为它是连词，有的词书认为它是副词。之所以将其视为副词，也许是因为像许多副词一样不仅能位于句首，而且能位于句中(注意前后使用逗号)，甚至句末(注意其前也用逗号)。如：Later,however, he changed his mind.可是他后来改变了主意

32、。He hasnt arrived. He may, however, come later.他还没有到，不过他等会儿可能会来。He said that it was so; he was mistaken, however.他说情况如此，可是他错了。注：以上各例中的however不能换成but，但可用but来改写：He said that it was so, but he was mistaken.他说情况如此，可他错了。but与however的用法区别两者均可表示转折或对比，意为“但是”、“可是”、“然而”等，但有区别：1.表示转折时，but是连词。如：He is young but v

34、rrived.

35、 hard. However, I think we should go out.雨下得很大，但我想我们还得出去。注：上例中的however不能换成but，但可用but来改写(注意所用标点的变化)。如：Its raining hard, but I think we should go out.如何理解in that引导从句的用法如果是作为自由搭配in that，那么它的意思需视上下文而定。如：Put the bookcase in that corner.把书柜放在那个角落里。You ought on no account to take part in that.你千万别参与那事。It i

36、s expensive to stay in that hotel.住那家旅馆很贵。如果用in that引导从句，则它是一个习语，意思是“因为”“由于”，与从属连词because意思相同。如：She was fortunatein thatshe had friends to help her.她很幸运，有一些朋友帮助她。The situation is rather complicatedin thatwe have two managing directors.由于我们有两位总经理，所以情况很复杂。Im in a slightly awkward position,in thathes n
