省略句

为了使话说得简明扼要,英语句子中某个单词、短语甚至从句或主句都可以省去。

这种省去句子某些成分而保持句子意思不变的现象,称为省略(ellipsis)

Ⅰ、状语从句中的省略用法

一、如果从句的主语和主句的主语一致,且从句的谓语含有be动词的某种形式

(am/is/are/was/were),可同时省略从句的主语和be动词的某种形式。

1、when,while引导的时间状语从句

e.g. Do be careful when (you are) crossing the street.

When/While (I was) on my way to work, I met her.

2、if,unless,once引导的条件状语从句

e.g. If (it is) properly treated, waste will do no harm to the environment.

I’ll not go to the party unless (I am) invited.

Once (you are) caught stealing in a supermarket, you will be punished.

3、though,although,whether,no matter whether/what/how/who等引导的

让步状语从句

e.g. He was happy, though/although (he was) poor.

Whether (she is) sick or well, she is always cheerful.

No matter how/However hard the task (is), we must fulfill it in time.

(注:从句的主语和主句的主语不一致时,只省略从句中的be动词形式)

4、as if,as though引导的方式状语从句

e.g. He rubbed his eyes and yawned as if/though (he was) waking up after a

long sleep.

He stood up as if/though (he wanted) to leave.(as if/though + to do表示一个将来的动作)

二、than,as引导的比较状语从句中的省略用法:当不同的主语进行比较时,

一般省略从句中的谓语;当从句中的主语与谓语(be动词除外)和主句中的主语与谓语相同时,通常省略从句中的主语和谓语,只保留比较部分。

e.g. He is taller than his brother (is).

I have as much as confidence in you as (I have confidence) in him.

三、以if从句为代表的状语从句中的特殊省略用法:通常省略了it is,that is,

there is/are。

e.g. If (it is) possible/necessary, this old temple will be rebuilt.

If (that is) so, I will call you back at 5:00 pm.

There are only a few books in our school library, if (there are) any.

Ⅱ、定语从句中的省略用法

关系词的省略关系代词that,which,whom等在限制性定语从句中充当宾语且不位于介词之后时,可以省略;in which或that在先行词way后作方式状语从句时可省略。

e.g. The man (that/who/whom) you visited last night is my grandpa.

I don’t like the way (in which/that) you treat the girl.

Ⅲ、虚拟语气中if及should的省略

1、当条件状语从句中有were,had,should等时省略if,把它们提至句首,形

成倒装句。

e.g. If I were a teacher, I would be strict with my students.

= Were I a teacher, I would be strict with my students.

2、Suggest,insist,order,require等表示建议、要求、命令的动词后接的从句

中,谓语动词常用―should+动词原形‖,should可以省略。

e.g. The doctor suggested that he (should) try to lose weight.

Ⅳ、不定式符号to的省略

1、感官动词see,hear,feel,watch等和使役动词have,make,let等后接不定

式作宾语时,不定式省略to。(一感feel,二听hear, listen to, 三让have, let, make,

四看see, look at, observe, watch)

2、do nothing but,can’t help but等结构常接省略to的不定式。

E.g. We didn’t do anything but stay at home watching TV yesterday.

Hearing th e news, she couldn’t help but cry.

3、在特定语境中为了避免重复,当不定式再次出现时,在want,wish,hope,

try,plan,like,love,hate后往往只保留to,而省略后面的动词。但不定式后有be,have时,也保留be和have。

E.g. My parents encouraged me to go to college, but I didn’t want to.

Ⅴ、So和not的替代性省略

用于避免重复前面所说过的内容,替代词so/not替代肯定或否定的名词性从句。可与believe,do,expect,fear,guess,hope,say,speak,suppose,think,I’m afraid等连用

e.g. – Do you suppose he is going to attend the meeting? – I suppose not.

Ⅵ、日常交际中的省略

在情景会话中,答语常常省略不会引起歧义的主语、谓语或宾语部分,而只保留对方希望了解的内容。在复合句或并列句中,也有省略主、谓、宾的情况。

e.g. – How many copies do you want? -- (I want) Three copies, please.

-- Have you ever been to the Great Wall? -- No, (I have) never (been to the Great Wall).

高中英语语法——并列句和状语从句

第12讲并列句和状语从句两个或两个以上的简单句用并列连词连在一起构成的句子叫做并列句,其基本结构是“简单句+并列连词+简单句”。并列连词有:and, but, or, so等。状语从句是在句子中起副词作用的句子。根据状语从句在句中不同的作用可分为:时间、地点、原因、目的、结果、条件、方式、让步和比较状语从句。并列连词和从属连词是高考的重要考点之一,在语法填空中通常以无提示词的方式进行考查,在短文改错中主要考查并列连词和从属连词的误用。并列句和状语从句的考点如下: 核心考点01考查并列连词 并列连词是用来连接两个或多个并列的词、短语或句子的词,主要表示并列、选择、转折、因果等关系。并列连词在句子中位置比较固定,必须位于所连接的并列单位之间;两个并列连词不能并用。 1.表示并列关系的连词 表示并列关系的连词有and,both...and...,not only...but also...,neither...nor...等。 2.表示选择关系的连词 表示选择关系的连词有or,either...or...等。 3.表示转折关系的连词 表示转折关系的连词有but,yet,while等。 4.表示因果关系的连词 表示因果关系的连词有for,so。 We listened eagerly, for he brought news of our families. 5.when作并列连词的用法

when除了作从属连词,引导时间状语从句外,还可作并列连词,其意义为“这时,那时”,相当于and at this/that time。常用于下列句式: ①sb.was doing sth.when... ②sb.was about to/going to do sth.when... ③sb.was on the point of doing sth.when... ④sb.had just done sth.when...。如: We were having a meeting when someone broke in. 我们正在开会,这时有人闯了进来。 6.while作并列连词的用法 while除了作从属连词,引导时间状语从句外,也可作并列连词,意为“而,却”,表示对比。如: He likes pop music, while I am fond of folk music. 他喜欢流行音乐,而我喜欢民间音乐。 I like playing the piano while my sister likes playing the violin. 我喜欢弹钢琴,而我妹妹喜欢拉小提琴。 典例分析1 (2017北京卷)—Peter, please send us postcards_________ we’ll know where you have visited. —No problem. 【解析】句意:——彼得, 请给我们邮寄明信片, 这样我们就能知道你参观过哪些地方。——没问题。根据句意可知,第一句中前后两个分句为因果关系, 所以填so。 【答案】so 典例分析2 He is a shy man, _________he is not afraid of anything or anyone. 【解析】句意:他是一个腼腆的人,但是他不惧怕任何人和任何事。根据前后句意可知,这里需要一个表示转折关系的连词。 【答案】but 典例分析3 You have to move out of the way_________ the truck cannot get past you. 【解析】句意:你得让让路,不然卡车过不去。根据句子结构和句意可知,空格处应该用or,表示一个否定的条件,意为“不然的话”。 【答案】or

高中英语语法权威解析九--- 祈使句

第9讲祈使句 一. 祈使句的句式特征 祈使句常常是表达说话人对对方的劝告、叮嘱、请求或命令等。因此,祈使句中一般没有主语,但根据其句意,实际上是省略了主语you。祈使句句末用感叹号或句号,朗读时,常用降调。在表达请求或劝告时,在祈使句前或句末可加, 上please,以使句, 子的语气更加缓和, 或客气。祈使句一般没有时态的变化,也不能与情态动词连用。例如: Keep off the grass!勿踩草地! Put the boxes in the small room.把那些盒子放到那个小房间里。 二. 祈使句的肯定句式 祈使句的肯定句式一般分为以下三种类型: 1. 行为动词原形+其他成分。例如: Make sentences after the model.根据例句造句。 2. Be动词+其他成分(形容词、名词或介词短语等)。例如: Be careful when crossing the street.过马路时要小心。 3. Let, +宾语+动词原, 形+, 其他, 成分, 。例如: Let him go back now.让他现在回去吧。 三. 祈使句的否定句式 祈使句的否定句式,通常情况下在句首加上Don’t或Never,一般分为以下四种类型:1. 在祈使句的肯定句式前加Don’t,构成“Don’t+行为动词原形+其他成分”。例如:Don’t say that again!别再那样说了! 2. 在Be动词引起的肯定祈使句前加Don’t,构成“Don’t be+其他成分(形容词、名词或介词短语等)”。例如:Don’t be careless.不要粗心。 注意:在这种句型中be不能省略;否定副词not不可置于be之后。 3. Let引起的祈使句的否定形式有两种:(1)Let开头的祈使句,如果后面跟第一、第三人称名词或代词的宾格,可在Let前加Don’t,也可在Let后宾格的名词或代词后面加not。(2)如果以Let’s开头的祈使句,必须在Let’s后加not。例如: Don’t let me go with her tomorrow. =Let me not go with her tomorrow. 不要让我明天跟她一起去。 Let’s not tell her the truth whenever we meet her. 无论什么时候我们碰到她,都不要告诉她真相。 4. 在公共场合的提示语中,否定祈使句常用“No+名词/V-ing形式”结构,表示“禁止做某事”。例如: NO PHOTOS! 禁止拍照! 四. 祈使句的反意问句 祈使句的反意疑问句须按其句子结构及讲话人的语气来决定其疑问部分。通常有以下三种式: 1. 祈使句为肯定句式,其反意疑问句表示请求时,通常用will you;表示邀请、劝说时,用won’t you。例如: Be sure to write to us, will you?你一定要给我们写信,好吗? Come to have dinner with us this evenin g, won’t you? 今晚来和我们一起吃饭,好吗? 2. 祈使句为否定句式,其反意疑问句通常只用will you。例如: Don’t smoke in the meeting room, will you? 不要在会议室抽烟,好吗? 3. Let开头的祈使句构成反意疑问句时,除Let’s用shall we外,其他均用will you。例如:Let the boy go first, will you?让个那男孩先走,好吗? Let’s take a walk after supper, shall we? 晚饭后我们去散步,好吗? 五. 祈使句的回答 祈使句的动作通常是表示将来发生的动作,所以回答祈使句时,一般用will或won’t。在回答具有否定意义的祈使句时,要注意两点:一是“形式一致”,即Yes与will保持一致;No与won’t保持一致。二是“意思相反”,即Yes是“不”的意思;No是“是”的意思。在回答时,要注意分析上下文语境中所提供的条件。例如: --- Don’t go out, please. It’s raining heavily outside. 请不要出去。外面雨下得很大。 ---- Yes, I will. I have to meet my brother at the airport.

高考英语语法专项突破训练专题16-倒装句和省略句

专题十六倒装句和省略句重难点分析 一、倒装句 倒装句主要考查以下几个方面: ◆含有否定意味的词置于句首,用部分倒装; ◆“only+状语/状语从句”置于句首,用部分倒装; ◆so/such…that句型中,“so+形容词/副词”提前,用部分倒装; ◆表示方位的副词或介词短语放在句首,要用完全倒装。 1. 倒装句用法一览表:

2. 特别提示 (1) there be结构的倒装句型中,除了be动词之外,there后还可接lie, live, seem to be等。如:There lived an old man in the village long long ago. 很久很久以前,村子里住着一位老人。 (2) here, there, now, then, up, down, away, out等副词位于句首,主语为代词时不到装。如:Away it flew. 它飞走了。 (3) 直接引语的一部分或全部位于句首,主句倒装,主句倒装,但是主语为代词时不倒装。如:“You have to finish it tonight,” she said. “今晚你必须完成它,”她说。 (4) so位于句首不倒装的情况:

① 主语与前句相同,表赞同,译为“确实如此”。如: — Mike studies hard. 迈克学习很刻苦。 — So he does. 确实是。 ② 表示前句内容也适用于另外的人或事,前句如果列举了两种事实以上,用“so it is/was with sb./sth.”回答。如: — Tom is kind and often helps those in trouble. 汤姆很友好,经常帮助处于困境中的人。 — So it is with his father. 他父亲也是。 (5) 使用as/though进行倒装时注意: ①句首有名词,名词不能带任何冠词。如:Child as he is, he can tell right from wrong. 尽管他是个孩子,却能够明辨是非。 ②句首是实义动词时,其他助动词则放在主语之后。如果实义动词有宾语和状语,则宾语和状语随实义动词一起放在主语之前。如: Try hard as he will, he never seems to be able to do the work satisfactorily. 虽然他尽力了,但他的工作总做得不尽如人意。 (6) not until位于句首的倒装结构中,如果是复合句,只有主句用倒装,从句不用。如: Not until he loses his health will he give up smoking. 他直到失去健康才会戒烟。 二、省略句 高考命题导向:省略是一种避免重复,保持简洁的语法手段。缺少一个或一个以上的必要语言成分,但在一定语境中能够独立存在,意义明确,并且能发挥交际功能的句子叫作省略句。高考主要是考查省略在固定结构中的运用。 省略句用法一览表:

高中英语语法教学的重要性及策略

高 考 ?学科教育? 二○ 一三年 八月 81 高中英语语法教学的重要性及策略 盐城市伍佑中学 宋 政 摘 要:本文从教师和学生的心理来分析问题,发现了现代英语教学过程中对待语法知识的一些误区,阐述了语法教学在高中英语教学中的重要性,然后根据自己的理解和经验总结出了一些关于英语语法教学的方法,这些方法更重要的是培养学生的自主学习能力。 关键词:高中英语;语法教学;有效性策略;自主学习; 一、英语语法教学的重要性 在高中英语教学的过程中,有很多老师不太在意语法的教学。在应试教育的背景下,只注重学生的听、说、读、写、译这五个方面,忽视了语法的重要性。了解语法,对于学习一门语言极其重要,它能够帮助我们更快更好的理解语言并运用语言。所以,在高中英语教学过程中,让学生熟练的掌握英语语法,十分必要。高中生学习英语已不是初次接触,所以早已没有开始学习的热情,随着英语的深度和难度的加大,当老师讲解语法知识时,会感到困惑,觉得英语学习碰到了瓶颈。尽管买了一大堆的资料,练习翻译、写作,却发现效果不明显。 英语学习是一个全面的过程,包括听、说、读、写、译和语法,语法更是其中最重要的一个方面。只有掌握了语法,才能更为深入和全面的了解英语,才能更为直观的了解作者想要表达的意思。通过老师在课堂上对英语书中知识的讲解,学生会对英语有一些了解,但这些并不足以让他们熟练的运用英语,这就需要用有效方法去学习语法,使得英语的学习更加规范和全面。教授学生英语语法知识,有助于提高学生的英语成绩,为日后学生的英语交流打下基础。因此,英语语法的教学不能忽略,老师要运用有效的、有策略的方法让学生系统的接受语法知识。 二、英语语法教学的策略 1、明确教学任务,分清重难点。 高中生所要接触的语法内容很多,比如各种从句、直接引语、间接引语和情态动词等,这些内容前后联系,复杂繁琐,需要老师从整体上系统具体的把握这些知识点,以便于教学过程中能够得心应手。同时,老师也要对自己学生的语法基础有大概的了解。再者,老师的教学过程要有重点,不能没有层次。要注意分析学生的作业和试卷,整理出学生易错的知识,并加上自己对语法的了解,然后在课堂上把整理出来的重点详细讲解,其他内容大概讲解,对于个别同学提出的问题要认真对待,确保每个学生都能理解这些语法知识。 2、把语法知识融入日常教学,并循环复习。 有些老师会仔细地把自己的教学任务分成好几部分,然后按照自己的安排决定每节课所要教的内容。我觉得这并不科学,任何一门语言都是整体的,不能够把它分成多少部分来教学,语法是贯穿整个语言之中的。在英语教学过程中,如果老师一下子把所有语法都交给学生,学生是无法接受的,他们的能力有限,如果一次性要学的东西很多,那就容易弄混、弄错,甚至什么都没记住。因此把语法只是融入日常的教学环节,是明智之举。艾宾浩斯的遗忘曲线规律告诉我们,人们接受信息时是短时记忆,会遗忘,只有及时的复习才能变成长时记忆。循环复习知识点,有助于加深印象,在教学过程中,老师要有耐心,要不厌其烦的讲解同一个知识点。 3、理论联系实际,培养学生自主能力。 老师在教学过程中要注意理论与实际相联系,把语法结构用在平时的交流中,让学生在实际的语言中去感知、理解、 记忆,从而更有效地掌握语法。高尔基说过,书籍是人类进 步的阶梯。看书是人们获取知识的重要途径,但很多学生不知道该怎么看,老师可以推荐一些比较好的语法书给学生,让他们利用课余时间去看。重要的是要让他们学会自己发现问题、提出问题及解决问题,培养他们自主学习的能力,这时老师应该充当的是辅助学习的角色,《英语课程标准》中也指出要以学生为主体的思想。 4、多样教学,活跃课堂气氛。 理论上来说,学习应该是一个快乐的过程,但由于我国的特殊背景,高中的课堂一般都异常沉闷,不像国外,课上随意发言,老师和学生像朋友一样交流问题。而且由于我国高中生课程较多,英语不是唯一课程,课后用来学习英语的时间也不多,因此英语的运用能力得不到锻炼,语法知识就不会很好。在课堂上,老师可以为学生创造出一些情境,让他们自由发挥,提高交际能力,激发学生对英语的学习兴趣。老师一味的用枯燥的专业名词讲解语法势必会让学生感到无聊乏味,如果能增加教学的趣味,就能够带来意料之外的好结果。比如有些琐碎的知识点,一个个记很麻烦也不一定能够记住,这时可用顺口溜,语句简短,趣味性也不错,这就可以引起学生的兴趣,就容易记住那些本来不易记住的东西。同时,也可以推荐学生多看一些好的美剧和英语书籍,既可以放松心情也可以学习知识,一举两得。 5、结合对比归纳法。 英语语法复杂繁琐,有很多规则相似,但不易区分,尤其在运用时,学生很容易搞错。在教学过程中,老师除了要及时帮助学生改正错误,还要帮助他们发现规律,运用对比归纳法发现区别,加深印象。例如在学习名词性从句时,可以对比以下句子,分清各是什么从句: ①She dose not know when Marry will come back.②The question is when Marry will come back.③When Marry will come back is not known yet. ④They have no idea about when Marry will come back. 让学生仔细比较四个斜体的句子,尽管都是when Marry will come back 但由于位置不同,句子结构也不同,学生可以发现第一个宾语从句,第二个是表语从句,第三个是主语从句,第四个是同位语从句。然后老师将名词性从句的词序特征、四类连接词和关系代词的使用方法进行对比和归纳,让学生能全面了解名词性从句,从而达到让他们正确运用的目的。 总而言之,语法教学是一个长期而艰巨的过程。作为教师,应不断的学习,提高自身业务能力,可以针对不同的教学目标和内容,采用不同的教学方法。语法的教学过程不是一味地让学生接受知识,而是要让学生灵活运用知识。老师在教学过程中,要精心设计教学活动,并注意语法知识与其他英语知识的融合,使学生更好地理解所学知识。

解析:once一旦。句意:一旦造成损害,土地要好多年才能恢复。 5.We need to get to the root of the problem__before__we can solve it. 解析:本题考查状语从句的连词。before表示“主句发生在从句之前”。句意:在我们解决问题之前,我们需要找到问题的根源。 6.__Although/Though__the job takes a significant amount of time,most students agree that the experience is worth it. 解析:although/though虽然(表示“虽然”时,不在后面使用连词but,不过有时它可与yet,still,nevertheless等副词连用)。句意:虽然那个工作要花大量的时间,但是大多数学生都觉得这次经历是值得的。 7.That's why I help brighten people's days.If you__don't__,who's to say that another person will? 解析:考查if引导的条件状语从句。在if引导的条件状语从句中,如果从句谈论的是一个有可能发生的事实及其产生的相关的结果,主句用一般将来时态,从句用一般现在时态。此句中的who's to say that another person will用的是将来时,故if引导的条件状语从句要用一般现在时。句意:这就是为什么我要使人们的日子变得鲜活起来。如果你不这样做,你说谁会这样做? 8.There is only one more day to go__before__your favorite music group play live.

按:本套资料省去了名词、代词、形容词等部分,保留了最最核心的句型和动词。希望能有所帮助。 第一章名词性从句 在句子中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 一.主语从句 主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。 1. It作形式主语和it引导强调句的比较 It作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。被强调部分指人时也可用who/whom。例如: a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 - b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。(强调句型) d) It is John that broke the window.是John打碎的窗户。(强调句型) 2. 用it作形式主语的结构 (1) It is +名词+从句 It is a fact that …; It is an honor that…; It is common knowledge that… (2) It is +形容词+从句 It is natural that…It is strange that… . (3) It is +不及物动词+从句 It seems that…It happened that…It appears that… (4) It +过去分词+从句 It is reported that…It has been proved that…It is said that… 3. 主语从句不可位于句首的五种情况: (1)if引导的主语从句不可居于复合句句首。 (2)It is said /reported…结构中的主语从句不可提前。例如: 正确表达:It is said that President Jiang will visit our school next week. ( 错误表达:That President Jiang will visit our school next week is said. (3)It happens/occurs…结构中的主语从句不可提前。例如: 正确表达:It occurred to him that he failed in the examination. 错误表达:That he failed in the examination occurred to him. (4)It doesn’t matter how/whether …结构中的主语从句不可提前。例如: 正确表达:It doesn’t matter whether he is wrong or not. 错误表达:Whether he is wrong or not doesn’t matter. (5)含主语从句的复合句是疑问句时,主语从句不可提前。例如: ; 正确表达:Is it likely that it will rain in the evening 错误表达:Is that will rain in the evening likely 4. what 与that 在引导主语从句时的区别 what 引导主语从句时在句时在从句中充当句子成分,如主语.宾语.表语,而that 则不然。例如:

(2)as与which的区别 a、位置不同 as可放在主句后,主句前或主句中间;which只能放在主句后。 b、as起连接作用,表达说话人的观点、看法,并指出主句内容的根据或出处,意为“正如,正像”。 Which相当于并列句,可以用and this来代替,意为“这一点,这件事’”。 注意:as常用于下列结构:as we know/ as is known to all, as we all can see, as has been said before/above, as might be excepted, as is often the case, 一般不能用which代替as。 c、在从句中作主语时,which既可作系动词be的主语也可作实义动词的主语,而as只可作系动词be的主语。 二、只用that不用which的情况 1、.先行词为all , much, everything, nothing , something ,anything, nothing, none, the one等不定代词时 2、先行词被only, any, few, little, no , all, just , very ,right等修饰时. 3、当先行词是最高级或被形容词最高级修饰时。

高中英语重点语法知识汇总(最新整理)

介词和介词短语 1、介词是一种用来表示词与词、词与句之间的关系的虚词,在句中不能单独作句子成分。介词后面一般有名词代词或相当于名词的其他词类,短语或从句作它的宾语。介词和它的宾语构成介词词组,在句中作状语,表语,补语或介词宾语。介词可以分为时间介词、地点介词、方式介词和其他介词。 1)时间介词:at, in, after, by, before, during, since, for, until, from 2)地点介词:in, at, on, over, under, below, near, behind, by 3)方式介词:with, by, like, in, without等 2、介词和其他代词或名词搭配形成介词短语。介词短语在句中可以作状语,定语,表语,补足语等。 1)作表语例如:It was in 2005 in Beijing. 2)作宾语补足语例如:He found his dog outside the station. 3)作后置定语例如:I even store them in boxes under my bed. 4)作状语例如:You are supposed to put your bread on your plate. 状语从句 1、地点状语从句地点状语从句通常由where, wherever 引导。 Where I live there are plenty of trees. 我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。 2、方式状语从句方式状语从句通常由as, (just) as…so…, as if, as though引导。 1)as, (just) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是“正如…”,“就像”,多用于正式文体,例如: Always do to the others as you would be done by. 你希望人家怎样待你,你就要怎样待人。 As water is to fish, so air is to man. 我们离不开空气,犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds.正如打扫房屋一样,我们也要扫除我们头脑中落后的东西。 2)as if, as though 两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气, 表示所说情况是事实或实现的可能性较大。汉译常作“仿佛……似的”,“好像……似的”,例如: They completely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实,就仿佛它不存在似的.(与事实相反谓语用虚拟语气)

高中英语语法并列句讲解

并列句 概念 两个或两个以上的简单句用并列连词连在一起构成的句子,叫做并列句,其基本结构是“简单句+并列连词+简单句”。并列连词有:and,but,or,so等.并列句中的各简单句意义同等重要,相互之间没有从属关系,是平行并列的关系。它们之间用连词连结。 如: I like action movies but don't like thrillers. Hurry up or you'll be late. (快点,否则你要迟到了。) and,or和but都是连词,在句中连接两个或两个以上的并列成分。可连接两个词,两个短语,两个分句,但所连接的两个成分必须一致,绝不能一个是词,一个是句子。如: I like red and orange. He isn't my brother or my friend. I like playing football and swimming. and 的意思是“和”,表示前后两个成分的并列或对称关系;or的意思是“或者”、“否则”、“要不然”,表示两个成分并列或选择关系;but 的意思是“但是”,表示两个成分之间的转折关系。 并列句中:1.表并列关系的由and,both...and,as well as,not only...but (also),neither...nor等组成。 She not only sings but also dance. 2.表转折关系的与but,however(然而),while(然而),still,yet等连用。 The film is not perfect,still,it's good. 3.表选择关系的由or,either...or...,not...but...,or else(否则)连接 Take the chance,or else you will regret(后悔)it. 4.表因果关系的与for,so/so that,therefore(因此),because等连用。
