  • with的用法

  •   英语学*最基础的就是词汇量的积累,大量的词汇积累是我们学*英语最重要的。小编为大家精心准备了with的用法,欢迎大家前来阅读。

      with词义

      1.和……一起;由……陪同;有……在场

      Would you like to go to the theatre with us?

      你愿意和我们一齐去剧院看戏吗?

      The money is on the table with the shopping list.

      钱和购物清单都在桌子上呢。

      2.随着

      With time passing by, they have grown into big boys and girls.

      随着时光的流逝,他们都长成大小伙子和大姑娘了。

      The shadows lengtheded with the approach of sunset.

      随着太阳下落,影子也逐渐伸长。

      3.用(表示使用工具或器具)

      It is easy to translate with a dictionary.

      借助字典进行翻译就会很容易。

      You can see it with a microscope.

      用显微镜就能看见它了。

      4.带有(能够作定语,也能够表伴随)

      We need a person with a knowledge of European markets.

      我们需要一个熟悉欧洲市场的人。

      He looked at her with a hurt expression.

      他带着受伤的神情看着她。

      5.因为;由于

      The small child trembled with fear.

      这小孩吓得直打哆嗦。

      It is very stuffy in the room, with all the windows closed.

      由于窗户都关着,屋子里十分闷。

      6.尽管

      With all her faults he still loves her.

      尽管她有那么多缺点,可他仍然爱着她。

      7.用以表示方式、情景、环境或条件

      I'll do it with pleasure.

      我很高兴做这件事。

      She fell asleep with the light on.

      她开着灯睡着了。

      辨析

      1.and 和with

      两者都有“和”的意思。and是连词,with是介词。当and连接两个主语时,谓语动词必须是复数;而with要看“真正主语”的单复数,也就是with前方的名词。如:

      Tom and his mother often _________(go) shopping on weekends.

      Tom with his mother often _________(go) shopping on weekends.

      and连接两个主语,Tom和妈妈,两个人肯定是复数,所以要用动词原形go; with 要看前方的主语,是Tom一个人,所以要用单数goes

      2.as和with

      两者都有“因为”“随着”的意思。不管什么意思,两者的核心区别就在于:as要接从句;with只接短语

      With our teacher ing, the class bee silent.

      As our teacher es, the class bee silent.

      with结构的构成

      它是由介词with或without+复合结构构成,复合结构作介词with或without的复合宾语,复合宾语中第一部分宾语由名词或代词充当,第二部分补足语由形容词、副词、介词短语、动词不定式或分词充当,分词能够是此刻分词,也能够是过去分词。

      With结构构成方式如下:

      1. with或without-名词代词+形容词;

      2. with或without-名词代词+副词;

      3. with或without-名词代词+介词短语;

  • for的用法

  • for的用法

      大家应该都是认识for吧,for是作为一个常见的英语介词,用法很多,了解它的用法,可以为自己学*英语提供了很多方便。下面是小编给大家带来的for的用法,以供大家参考,我们一起来看看吧!

      for是个常用词,在英语中出现频率高、含义多、用法广,可以与许多名词、形容词和动词搭配。下面举例说明,希望对同学们学好、用准英语知识能够有所帮助。

      一、用作介词。

      1.表示目的,意为“为了”。例如:

      Ann goes home for holidays every year with her parents.安每年与她父母一起回家度假。

      此外,下列动词后跟双宾语,起间接关系作用的介词for均表目的。get/buy/make/draw/play(播放,上演)/save(节约)/find/fly/mend/take/do sb. sth.=get/buy/make/draw/play/end/take/do sth. for sb.

      2.表示对象、用途,意为“对于,供,适合于”。例如:

      Walking is good for health.散步有利于健康。

      Here are books for children.这些是供儿童阅读的书籍。

      3.表示目标、去向,意为“往,向”。例如:

      I’ll leave for Shanghai.我要前往上海。

      What time do you leave home for school?你何时离家上学?

      4.表示等值或交换关系,意为“兑,换”。例如:

      We can get two tickets for eight yuan.用八元钱,我们可以买两张票。

      Don’t put the whole English sentence word for word into Chinese.不要把整个英语句子字对字地译成汉语。

      5.表示愿望、爱好、特长等,意为“对于”。例如:

      He hopes for the best.他抱着乐观的希望。

      The children in China long(vi.渴望) for the Mid-Autumn Festival.*儿童盼望中秋节。

      6.表示原因,意为“由于,因为”。例如:

      He has lived there for nine years.他在那里住了九年。

      You can see nothing but trees for two miles.(www.fwsir.com)两英里之内,你只能看见树木。

      8.与名词或代词连用,后接动词不定式,构成名词短语。其中介词for后面的名词或代词在逻辑上是不定式的主语。例如:

      Are you for or against?你是赞成还是反对?

      How many of you are for the idea?你们多少人赞成这个意见?

      11.意为“当做,作为”。例如:

      We often mistake Lucy for Lily.我们时常把露西当做莉莉。

      Most of the houses are used for the teachers’ offices now.这些房子现在多数用作教师的办公室了。

      12.意为“至于,就……而言……”。例如:

      He is tall for his age.就年龄而言,他算是高个子。

      二、用作并列连词,表示因果关系,意为“因为”。

      并列连词for引导的表示原因的从句不能用于句首,较because正式,用于正式文体中,但语气比because弱;回答why引导的问句时,应用because,而不能用for。例如:

      You’d better put on your sweater,for it’s rather cold outside.你最好把毛衣穿上,外边相当冷。

      I must be off now,for my sister is waiting for me.我得走了,因为我姐姐在等我。

      三、用于某些成语,构成固定词组。例如:

      1.for days(years) 连续多日(年)

      2.for ever 永远

      3.for long 长久

      4.long for 渴望

  • allow的用法

  • 英语,职场,考试
  • allow的用法

      导语:英语学*即学*英语,主要讲述学*英语的方法,注意事项等内容。学*英语贵在坚持,找到适合自己的方法,多运用多温故。以下是小编为大家整理的allow的`用法,欢迎阅读与收藏。

      allow 允许,准许

      用法:

      allow for sth. 允许某事

      allow doing sth. 允许做某事

      They dont allow smoking here.=They dont allow others to smoke here

      allow sb. to do sth. 允许某人做某事

      (注意被动:sb. be allowed to do sth.)

      1、allow意为“允许;许可”,常用于“allow sb. to do sth.”结构,表示“允许某人做某事”。allow后面可接动名词作宾语,不可用动词不定式作宾语,即: allow doing sth.“允许做某事”。如:

      My father allowed me to play basketball after finishing my homework. 我的父亲允许我做完作业后打篮球。

      They do not allow smoking in public. 他们不允许在公共场合吸烟。

      [注意] allow用于被动语态时,必须接不定式作宾语补足语,不能接动名词形式。“Sb. / Sth. be allowed to do sth.”结构,也可在allow后面接介词短语,即“Sb. / Sth. be allowed 介词短语”。如:

      Women were not allowed to take part in the games. 妇女是不允许参加这些比赛的。

      I dont allow dogs in the house. 我不允许狗进屋。

      2、allow意为“让……得到;同意给予”,后面接双宾语。如:

      How much money does your father allow you every week? 你爸爸每周给你多少钱?

      3、allow意为“承认”,后面可跟从句,也可跟“to be”复合宾语。如:

      We had to allow that he was the best teacher we had met. 我们不得不承认他是我们遇到的最好的老师。

      We must allow him to be a genius. 我们必须承认他是个天才。

      4、allow for 表示“考虑到;体谅”。如:

      You have to allow for the weather there. 你不得不考虑到那里的天气。

      5、allow还常与 out, in, up等副词搭配使用,即 allow sb. in / out / up等。如:

      The patient was allowed up after ten days. 十天后这位病人才被允许起床(下地)。

      [注意] 口语中常说Allow me!(让我来吧!),用于表示要抢先做某事,以表示客气。

      动词allow搭配小议

      1、其后可接动名词作宾语,但通常不接不定式:我们不允许在此抽烟。

      误:We don’t allow to smoke here.

      正:We don’t allow smoking here.

      2、若其后跟有间接宾语, 则可用不定式, 即可用于 allow sb to do sth:

      我父母不允许我深夜还留在外头。

      误:My parents don’t allow me staying out late.

      正:My parents don’t allow me to stay out late.

      3、其后不接不定式作宾语,但是被动语态之后可用不定式(此时的不定式不是宾语,而是主语补语):

      人们不准在此大声讲话。

      误:People are not allowed talking loudly here.

      正:People are not allowed to talk loudly here.

      正:We do not allow people to talk loudly here.

      析:上面误句主要是误认为 talking loudly 是动词 allow的宾语 (所以在其后接动名词), 而其实这是一个被动结构, talking loudly 不是动词 allow 的宾语, 而是主语 people 的补语。若将此转化为主动结构, 即为 allow sb to do sth 这一句型。

      4、关于allow for与allow of

      这些事实只能有一种解释。

      误:The facts allow for only one explanation.

      正:The facts allow of only one explanation.

      析:不要混淆 allow for(考虑到,体谅)与 allow of(容许,对.. .留有余地)。如:

      Don’t forget to allow for traffic delays. 不要忘记把在路上交通耽误的时间考虑在内

  • however的用法

  • 英语,职场,考试
  • however的用法

      英语单词的产生是汉英两种语言双向交流的产物,一些带有*特色的名称和概念进入了英语词汇,同时还有一些英语词汇进入了汉语,在文化环境中衍生出新的含义,形成了英语词汇的语义文化特征。以下是小编精心整理的however的.用法,欢迎大家分享。

      however

      [英][haev(r)][美][haev]

      adv.然而; 可是; 无论如何; 不管到什么程度;

      conj.不管怎样;

      1、用作副词,注意以下用法:

      (1) 表示让步,意为“无论如何”“不管怎样”,用来修饰形容词或副词,其词序为:however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能,用以引导一个让步状语从句。如:

      However much he eats, he never gets fat. 不管他吃多少,他永远吃不胖。

      However cold it is, he always goes swimming. 不管天有多冷,他都去游泳。

      However far it is, I intend to drive there tonight. 不管有多远,我今晚也要开车到那儿去。

      这样用的 however 与 no matter how 大致同义。如:

      No matter how much he eats, he never gets fat.

      No matter how cold it is, he always goes swimming.

      No matter how far it is, I intend to drive there tonight.

      有时从句谓语可用情态动词。如:

      Don’t laugh, however funny it may be. 无论多么有趣也不要笑。

      I’ll try to finish it in time, however hard it may be. 无论多么难,我也要按时完成。

      另外,“however+形容词或副词+主语+谓语”有时可以有所省略。如:

      I refuse, however favourable the conditions. 不管条件如何有利,我都不干。(conditions后省去了are)

      I’d rather have a room of my own, however small (it is), than share a room. 无论房间多么小,我宁愿一个人住一间,而不愿意与别人合住一个房间。

      A grammar rule, however true (it is), is useless unless it can be understood. 一条语法规则,不管如何正确,除非能懂,否则毫无用处。

      (2) 表示转折,尤其用于谈及一个既成事实时,表示转折,其意为“可是”“仍然”等。可放在句首、句中或句末,通常用逗号与句子其他成分隔开。如:

      My father, however, did not agree. 但是,我父亲不同意

      My room is small; however, it’s comfortable. 我的房间很小,但却很舒服。

      He said that it was so; he was mistaken, however. 他说情况如此,可是他错了。

      注意,however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号)。如:

      我们都已尽了最大的努力,不过我们还是输了。

      误:We all tried our best, however we lost the game.

      正:We all tried our best, but we lost the game.

      正:We all tried our best; however, we lost the game.

      正:We all tried our best. However, we lost the game.

      (3) 表示惊奇或强调,相当于how ever的用法,其意为“究竟怎样,到底以什么方式”。如:

      However did you get here without a car? 没有汽车你究竟是怎样来的呢?

      However does he manage to write music when he is so deaf? 他聋成这个样子,究竟是怎样从事作曲的呢?

      2、用作连词,引导方式状语从句,表示“无论以何种方式”“不管怎样”。如:

      However it may be, I shall take your word. 无论如何,我将会相信你的话。

      The painting looks wrong however you look at it. 这张画不论怎么看都显得不对劲。

      However you travel, it’ll take you at least two days. 无论你怎么个走法,至少要两天时间。

  • must的用法

  • 英语,职场,考试
  • must的用法

      一般来说must具有名词,情态动词,动词以及形容词等用法,而大家容易混淆的或者说比较重点的用法在于must作情态动词的用法,以下是小编为大家带来的must的用法,希望能帮助到大家。

      关于情态动词must的`用法,应注意以下几点:

      一、must表示“必须”、“一定要”:

      (1) 可用于肯定句、否定句或疑问句;用于否定句时,mustn’t的意思是“一定不要”、“不能”,而不是“不必”:

      You must finish it today. 你一定要在今天完成它。

      You must see the doctor. 你一定要看医生。

      Must you go so soon? 你一定得这么早就走吗?

      We mustn’t think only of ourselves. 我们可不能只考虑自己。

      (2) 主要表示现在或将来,但有时(如在间接引语中)也可表过去(=had to):

      She asked if she must (had to) leave. 她问她是否一定要离开。

      (3) 对于must 开头一般疑问句,若要作否定回答,可用needn’t,不用mustn’t:

      "Must I come over tonight?" "No, you needn’t." “我今晚必须过来吗?”“不必。”

      (4) 其后可接被动结构或进行形式:

      Something must be done to stop it. 必须采取措施来阻止它。

      I think I must be going. 我想我得走了。

      二、must表示推测

      其意为“准是”、“一定是”,注意以下几点:

      (1) 通常只用于肯定句,在否定句或疑问句用can代之:

      It must be true. 那一定是真的。

      比较:Can it be true? 那可能是真的吗? / It can’t be true. 那不可能是真的。

      (2) 后接动词原形,表示对现在情况的推测:

      He must be wrong. 他一定错了。

  • GMAT语法《NOT ONLY…BUT ALSO…》的用法

  • GMAT语法《NOT ONLY…BUT ALSO…》的用法

      “NOT ONLY…BUT ALSO…”是表示“不仅……而且……”的意思,那么他在句子中要怎么使用呢?下面是小编整理的关于NOT ONLY…BUT ALSO…的语法知识,欢迎阅读!

      NOT ONLY…BUT ALSO…

      看了GWD8-20, 以前的NN讨论的的太好了,可是藏的太深,很多人都看不见, 后来又看了好些的帖子,,收益良多.所以我把大家观点总结一下,

      首先Not only…..but (also)表示的关系是递进, 其中also可以省略

      But/but also表示的是转折. 在but also中, ring_cheng认为also不属于重复, 所以应当保留.该观点尚未证实.

      not only ...but also表示并列,不能表示转折,不要有先入为主的感觉认为not only...but also必须一起出现。单独出现but also是可能的.,此时表示的是转折,参见大全74

      All-terrain vehicles have allowed vacationers to reach many previously inaccessible areas, but they have also been blamed for causing hundreds of deaths, injury to thousands, and seriously damaging the nation’s recreational areas.

      (A)deaths, injury to thousands, and seriously damaging

      (B)deaths and injuring thousands, and serious damage to

      (C)deaths, thousands who are injured, as well as seriously damaging

      (D)deaths and thousands of injuries, as well as doing serious damage to (D)

      (E)deaths, thousands are injured, and they do serious damage to

      关于not only…but also.. 的用法,我根据前人的发言并结合GMAT的思路挑出了这几条:

      1.在正常语序中: not only … but also 应连接两个相对称的并列成分。例如:

      Not only Mr Lin but also his son joined the Party two years ago. (连接两个主语)

      I not only play tennis but also practise shooting. (连接两个谓语动词)

      He plays not only the piano but also the violin. (连接两个宾语)

      在正常语序中: 短语本身不可以加入其它成份,比如变成:not only...but it also...是错误的(因为破坏了*衡)。

      如大全中:

      125.The winds that howl across the Great Plains not only blow away valuable topsoil, thereby reducing the potential crop yield of a tract of land, and also damage or destroy young plants.

      (A)and also damage or destroy

      (B)as well as damaging or destroying

      (C)but they also cause damage or destroy

      (D)but also damage or destroy(D)

      (E)but also causing damage or destroying

      Choice D, the best answer, correctly employs the correlative construction not only x but also y, where x and y are grammatically parallel and where both x and y (damage and destroy)ap* to young plants. Choices A, (not only... and also), B (not only... as well as), and C (not only... but they also)violate the not only... but also paradigm. Moreover, B contains terms (blow... damaging)that are not parallel. In C and E, damage is used not as a verb with young plants as its direct object but as a noun receiving the action of cause; consequently, these choices fail to state explicitly that the damage is done to young plants. E also violates parallelism (not only blow... but also causing)

      2. not only … but also 连接两个主语时,谓语动词要和与其最*的主语保持人称和数的一致。例如:

      Not only the students but also the teacher was against the plan. / Not only the teacher but also the students were against the plan.

      3. not only … but also 不能用在否定句中。例如:

      误: They don't fear not only hardship but also death.

      正: They fear neither hardship nor death.

      正: They don't fear either hardship or death.

      4. not only … but also 连接两个分句,并且 not only 位于句首时,第一个分句中的主语和谓语要部分倒装。例如:

      Not only does the sun give us light, but also it gives us heat.

      Not only did he speak English correctly, but he also speaks it fluently.

      《新编英语语法》薄冰P633:Not only does he compose music, but he also play./ Not only does he have to type out the answer on a com*r, but he also gets the com*r to translate it into sounds.

      《新编英语语法》章振邦1005:She was not only compelled to stay at home, but she was also forbidden to see her friends

      英语语法大全上的例句是: Not only did they break into his office and steal his books, but they also tore up his manuscripts. 所以我个人认为在倒装的情况下,but also是可以被主语拆开的.

      这里附上ring_cheng的观点:倒装时可以在短语中插入某类成分,如:not only did sb do sth, but sb also did sth (之所以前后都加入主语,不是为了连接主语,而是为了句子的对仗工整而补足主语,连接的其实是主语的两个不同的谓语动作。又因为not only在句首已经倒装过了,所以but also用正常语序即可。依然满足句子*衡的要求).如大全354中but also被主语+助动词拆开:

      354.In 1978 a national study found that not only had many contractors licensed by a self-policing private guild failed to pass qualifying exams, they in addition falsified their references.

      A. they in addition falsified their references

      B. they had their references falsified in addition

      C. but they had also falsified their references

      D. they had also falsified their references(C)

      E. but their references were falsified as well

      (3)严重脏污领口、袖口、可用洗衣皂清洗后在放入洗衣机中。

      洗衣粉的使用误区

      误区一、泡沫越多去污力越强

      有的消费者错误地认为洗衣粉泡沫越多越好,实际上泡沫的多少和去污力没有直接联系。在洗衣服时,洗衣粉的量应加足,洗涤特别脏的衣服时多加一些是应该的,但并不是洗衣粉加得越多越好。当洗衣粉达到一定浓度,水溶液的表面活性达到最大值以后,去污力就不再随着洗衣粉的增加而增加了,反而有减少的趋势。实践证明:洗衣粉的浓度在0.2%~0.5%时,水溶液的表面活性最高,洗涤去污能力最强,也就是说,在一面盆的清水中加入5~10克(约1茶匙)的洗衣粉就足够了。洗衣粉加过量除了不会再增加去污效果外,还会因溶液中碱性的增加而对衣服纤维有损伤。另外,大量洗衣粉附在衣服上,泡沫多,不易漂净,费水、费时间,造成浪费不说,残留在衣物上的成分还会对皮肤造成伤害,引起过敏反应等。

      误区二、天然皂粉= 洗衣粉

      目前市场上出现了名叫天然皂粉的产品,很多消费者都以为也是一种洗衣粉,其实肥皂粉不完全等于洗衣粉。从功能上看,天然皂粉优于洗衣粉。它不含磷酸盐,且具有天然特性,因此对皮肤刺激性小、安全,且保护织物,对织物具有亲和性,洗后衣物蓬松柔软,解决了用合成洗衣粉多次洗涤后织物污垢积淀、织物硬化、带静电等问题。皂粉是超低泡型洗涤产品,更易漂清,所以更适合洗贴身衣物。由于天然皂粉添加了特种钙皂分散剂,其去污力更强。另外,香气浓郁,织物干后仍留有余香。

      误区三、洗衣粉不伤手

      由于洗衣粉市场竞争激烈,为了显示产品的“独特”功效,一些厂家别出心裁地推出“不伤手的洗衣粉”、“不伤手的洗洁精”等,意在多占一点市场份额。然而,这些被夸大的宣传很容易误导消费者。因为,合成洗涤剂在本质上归根到底都属于化工产品,去污的同时或多或少地都会对皮肤造成伤害。长时间接触后会导致皮疹、红斑、脱屑、湿疹等皮肤问题。如果通过皮肤过多地吸收到体内,还可能损害人体的造血功能、 淋巴系统和肝功能,有的甚至有致癌的危险。

      误区四、把洗衣粉当作洗碗剂

      有的家庭用洗衣粉洗 餐具,这是非常不好的。洗衣粉中的主要成分是烷基苯磺酸钠,具有中等毒性。如果它的微粒附着在餐具上通过胃肠道进入人体后,可抑制胃蛋白酶和胰酶的活动性,从而影响胃肠消化功能,同时还会损害肝细胞,导致肝功能障碍,久而久之,会使人腹泻、消化不良、肝肾异常、脾脏缩小、甚至致癌、导致血液疾病。因此,千万不要拿洗衣粉当洗碗剂来用。

  • that用法详解

  • that用法详解

      想要学好考研英语怎么能不知道that的用法呢?下面就让小编为大家详解一下吧。欢迎阅读收藏。

      that是英语中十分常见的单词,用法灵活多样,是英语中最常用的词汇之一。正因为它是我们认为自己最熟悉的单词,反而容易忽视它。在考研英语中,对that的考查包括三个方面:

      (1)that作指示代词的用法;

      (2)that作连词引导各类从句时,需要准确辨别从句类型。

      一、that 作限定词或代词

      that可以作限定词或代词连接名词或名词短语,也可单独使用,用以指代人或者物。此外,that不仅可以指代单独的人或物,还可以指代一句话。

      例:Furthermore, in the early days of long line fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now. [2006, text3]

      分析:

      A.分析句子结构。Furthermore, in the early days of long line fishing, a lot of fish were lost to sharks //after they had been hooked. That is no longer a problem, //because there are fewer sharks around now.

      第一个句子的主句为a lot of fish were lost to sharks,介词短语in the early days of long line fishing作状语,after引导时间状语从句。第二个句子主句是That is no longer a problem, that为代词,because引导原因状语从句。

      B.分析that指代。that指代第一句话,“a lot of fish were lost to sharks after they had been hooked”,其中after引导时间状语从句。

      C.译文:而且,在使用多钩长线捕鱼的初期,许多鱼被钩住后又被鲨鱼夺走。这不再是一个问题,因为附*的鲨鱼更少了。

      二、that作副词表示程度,相当于so

      例:It isn’t all that cold. 天没有那么冷。

      三、that作连词引导各类从句

      (1)that引导名词性从句

      that后面连接一个完整的陈述句,可以位于主语、宾语、表语或同位语的位置,分别引导主语从句、宾语从句、表语从句和同位语从句。此时,that没有实意,而且不在从句中做任何成分。that引导主语从句和同位语从句时不可以省略。

      例1:That the plates are movingis now beyond dis*. (主语从句)

      地球板块是在漂移的,这一事实毋庸置疑。

      例2:The truth is that everyone should take care of orphan, not just the authorities.(表语从句)

      事实是,所有人都应该照顾孤儿,而不仅仅是完全由*承担。

      例3:All people believed that it was right to rescue the temple. (宾语从句)(注:that可以省略)

      所有人都认为拯救古庙是正确的。

      例4:The students expressed their hope that they could be admitted by that university.(同位语从句)

      学生们表达了他们向被这所大学录取的愿望。

      (2)that引导定语从句

      that引导定语从句,在从句中充当主语、表语或者宾语,既可以指代人,也可以指代物。that在定语从句中作宾语时,引导词that可以省略。

      例1:The professor that you admire most will visit our university next month.

      你敬仰的那个教授下月会到我们学校参观。

      例2:This is one of the subways that will be put into use in two years.

      这是未来两年内将开通的地铁之一。

      例3:I have nothing that is worth reading.

      我没有什么值得一读的东西。

      (注:当先行词中有不定代词、形容词最高级、序数词或者先行词被the only,the very等限定词修饰等情况下,定语从句引导词也只能用that。)

      (3)that与其他单词结合引导状语从句

      that可以和其他单词结构共同引导状语从句,例如such...that,so...that等引导结果状语从句,in order that,so that等引导目的状语从句,in that,now that,on the grounds that等引导原因状语从句,suppose/supposing/assume/assuming/provided/providing that,on condition that等引导条件状语从句等。

      例1:She has made suchrapid progress thatbefore long she could pass the exam.

      她进步很快,不久就能通过考试的。

      例2:You should make full use of this opportunityso thatyou can get rich experience.

      你应该充分利用这次机会,以便获得丰富的经验。

      例3:Supposing thatyou were in my position, what would you do?

      如果你在我的位置,你会怎么做?

      例4:On condition thatyou were lost in the desert, you should ask for help as soon as possible.

      如果你在沙漠中迷路,你应该尽早寻求帮助。

      (4)that引导强调句

      “It is/was+被强调部分+that从句”是高频使用的一种强调句型,其中被强调部分可以作从句的主语、宾语和状语等。强调句中去掉“it is/was”和“that”后,句子成分和语义仍然完整。

      例:It was after the war was over that Einstein was able to come back to his research work again.

      战争结束后爱因斯坦才能重新进行他的研究工作。
