1.主谓一致

就近原则

1.由并列结构或连词(either…or,neither…nor,not…but,not only…but also,or 等)连接的并列主语,谓语动词与靠近的那个名词或代词保持一致。

2. 在倒装句和there be句型中,谓语动词与后面的第一个主语保持一致。

例句:There is a book and some pens on the desk.桌子上有一本书和几支钢笔。

3. 在强调句中,连接代词又在句中作主语,这时它应与被强调的主语保持一致。例句:It is Ma ry’s brother who was injured in the car accident. 是Mary 的哥哥在车祸中受伤了。

意义一致原则

1. 当主语与谓语动词之间插入along with,with,as well as,together with,no less than,besides,except,but,including等短语时,谓语动词不受这些插入语的干扰,依然和主语保持一致。

例句:I, along with my sister, am going to Shanghai next month. 我,还有我姐姐,打算下个月去上海。

2. 英语中有一类单、复数同型的词(people,means,sheep,deer,fish 等),其单、复数取决于它在句中的含义。

例句:All of the people in the country have been prepared for the great reformation.这个国家的人都已经为大变革做好了准备。

3. 多数情况下,由“what”引导的名词性从句作主语时,其后的谓语动词通常用单数形式。

例句:What I want to say is just “ Take care!”.我只想说:“多保重!”

4. 当主语与all,none,any,some等不定代词、形容词连用时,应根据具体句意,来决定其后的谓语动词的单复数。

例句:All I know about this company is what he told me yesterday.我对这家公司的了解都是昨天完他告诉我的。

5. “…+ (of) +名词”结构描述数量时,如果“of”后的名词为单数(不可数名词),则谓语动词用单数,如果名词为复数,则谓语动词用复数。

例句:Most of the water here is clean.大部分的水是干净的。

80% cotton has been sent to America.80%的棉花已经被送往美国。Half of the apples are red.有一半儿的苹果是红的。

6. 词组“a number of,a great/good many,a group of +可数名词复数”的结构作主语时,谓语动词应用复数;如果冠词a变为the,则谓语动词用单数。

例句: A number of ancient buildings are destroyed in the war.许多的古代建筑在战争中被毁。

The number of the visitors has decreased this year. 游客的数量今年减少了。

7. 英语的集体名词(committee, crowd, family, public, group, party, team, class, club, company, union ,clergy,

mankind,militia,police,people,poultry等词),指代“整体”时为单数;指代“其中的各成员”则为复数。

例句:My family was very poor when I was a little girl.当我还是一

个小女孩儿的时候,我家很穷。

My family are all looking forward for your coming. 我的家人都在期待着你的到来。

整体原则

1. 从句、不定式、动名词等作主语时谓语动词一律视作一个整体,谓语动词用单数。例句:When to leave has not been decided.什么时候离开还没有定下来。

Go shopping on Sunday is one of his habits.周日购物是他的一个习惯。

Note:如果主语是两个(或两个以上)的名词性从句,谓语动词常用复数。

例句:What he said and what he did were always different.他所说的和他所做的总是不一样。

2. 如果两个以上的名词组成一个整体概念作主语时,谓语动词须用单数。

例句:The novelist and poet is going to Europe next year.这位小说家兼诗人打算明年去欧洲。

The novelist and the poet are going to Europe next year.小说家和诗人都打算明年去欧洲。

3. 专用名词,如:书名、剧名、报刊名、国家(组织)名等,通常作单数用。

例句:The United States was found it 1776.美国成立于1776年。

4. 表示时间、距离、金额、度量等词语作主语时,通常被视作整体,谓语动词用单数。

例句:10 minutes is enough.十分钟足够了。

5.加减乘除等数学运算谓语动词通常用单数。

例句:2 times 3 makes 6. 二乘三等于六。

个体原则

1. and连结的两个或多个主语前如果有each, every, no等修饰语时(后面的一个有时也可省略),后面的谓语动词用单数形式。例句:Every man and every woman is busy at working.每个人都在忙着工作。

2. 英语句中的each,either,neither等词,既可作代词充当主语,又可作形容词修饰主语,这时的谓语动词一律用单数。

例句:Neither of us has been abroad. 我们谁都没出过国。

3. 由some, any every, no构成的复合词(somebody,nobody,everything,anything等)作主语时,谓语动词用单数。

例句:Somebody is waiting for you at the school gate.有人在学校门口等你。

4. many a / more than one + 单数名词,一般接单数谓语动词。

例句:Many a man does not understand Einstein’s relativity.许多人不明白爱因斯坦的相对论。

5. “one and a half + 复数名词”作主语,谓语动词一般用单数。

例句:One and a half hours has passed. 一个半小时过去了。

6. 成双成对出现的复数名词(glasses,scissors,shoes,trousers,pants,gloves,stockings等)作主语时,通常谓语动词用复数,但如果前面有a /the pair of;a /the suit of等词语时,则谓语动词要用单数。

例句:A pair of scissors is useful tool for a dressmaker.剪刀是裁缝

的重要工具。

7. 以“-s”结尾的“复数”名词(例如;一些学科名词mathematics,physics,politics等),或以“-s”结尾的地点名词、人名等词后面的谓语动词通常用单数。

taken thus far为设置的干扰项。由于主语为表示学科的单数名词,故谓语应是单数形式。

2.[答案]B.

[解析]表示重量、度量、衡量、价值的复数名词作主语,谓语动词常用单数形式。

3.[答案]D.

[解析]C项结构错误,可先排除;由and所连接的两个名词,如果and后面的名词前没有冠词,谓语要用单数。故D项为正确答案。

4.[答案]A.

[解析]cattle 是集体名词,在形式上是单数,但在句中往往作复数用,谓语动词用复数。这类名词常见的有:clergy mankind, militia, police, people, poultry等。

5.[答案]B.

[解析]此题主语是Mathematics,学科做主语时,是表示单数的意义的词,故只能在A、B两项中选择,而A时态不对, D. belong to属于。

6.[答案]C.

[解析] 当either, each, neither, everyone等不定代词作主语时,其后谓语需用第三人称单数。例如:a. Neither of these books is very new.这两本书都不新。 B. Each of the students brings a dictionary.学生各自带字典来。 C. Every man and woman is eligible to vote.每个男人或女人都有资格投票。

7.[答案]B.

[解析]表示数量的名词应做单数看待。

9.[答案]C.

[解析]There used to 句型上相当于there be句型,所以此处用be提问。动词的数应与后面的名词一致。

10.[答案]A.

[解析]cattle 是集体名词,在形式上是单数,但在句中往往作复数用,谓语动词用复数。这类名词常见的有:clergy

2).对过去事实的假设,从句谓语用过去完成式

3).对未来事实的假设,从句谓语用would+动词原型

情态动词

1.can 用于否定句cannot(help)but表示不能不,只能(but后跟不带to的动词不定式)

2.must 表示禁止,一定不要时的否定式为mustn’t 当它表示有把握的推断时意为一定准是时它的否定形式为can’t

there to be:作for 介词补语

作动词(except, want, like, prefer, hate…)的宾语

eg.

They planned for there to be another meeting

Members like there to be plenty of choice.

there being : 作除for外的介词的补语

作主语和状语

eg.

John was relying on there being another opportunity.

There being a bus stop so near the house is a good advantage.

2.存在句的非限定形式与限定形式的转化

eg. For there to be so few people in the street was unusual. = It was

unusual that there were so few people in the street.

存在句的谓语动词

存在句的谓语动词主要是动词be的某种形式,分限定形式和非限定形式。

限定形式:一般现在时、一般过去时、现在完成体、过去完成体和情态助动词+不定式。除be外,某些表示存在意义的不及物动词如:exist, remain, occur, stand, lie.等,能用于there存在句。地点状语前移,there可省。Eg.

一些特殊的结构

◆与more…than有关的:

1)mor e…than…是…而不是,与其说是…不如说是

eg.

She is more been than wise.

He is more a writer than an artist.

"more + than+原级形容词(副词)"结构,这是将不同性质加以比较,其中的"more"有"rather"的意思。

It is more than probable that he will fall.

"more than +动词"结构,这种结构表示动词的程度,可译为"异常","岂止","十二分地"等。

This more than satisfied me.

2)not so much …as与其说是…不如说是

eg. It wasn’t so much that I disliked her as that I just wasn’t

interested.

3)not more/er than与no more/er than

eg.

He is no richer than I= as poor as

He is not richer than I

4)more than 不止,超过

eg. She is more than pretty.

5) more than 简直不

eg. My trip to Beijing is more than sightseeing.

6). Not… any more than 不能..正如…不能

One cannot learn to sketch and express himself graphically only by reading about it any more than one can learn to swim while standing by the pool.

7)no more …than…

A home without love is no more a home than a body without a soul is a man.

8) “Nothing is more…than”和“Nothing is so …as”结构"Nothing is more…than"和"Nothing is so …as"都具有最高级比较的意思,"Nothing I"可换用"no","nobody","nowhere","little","few","hardly","scarcely"等等,可译为"没有……比……更为","像……再没有了","最……"等。

Nothing is more precious than time.

9) “not so much…as”和“not so much as …”结构,

"not so much…as"="not so much as …",其中as有进可换用but rather,可译为:"与其说是……毋须说是……"。而"not so much as"="without(not)even,"可译为"甚至……还没有"。

The oceans do not so much divide the world as unite it.

◆only (not, all, but, never) too …to do so “和”too ready (apt) + to do“结没有否定意义,凡是”not“,”all“ ”but等字后+“too…to,”不定式都失去了否定意义,在“too ready(apt)+to do”结构中也没有否定意义。

You will be but too glad to get home.

◆“cannot…too…”结构

"cannot…too…"意为"It is impossible to overdo…"或者,即"无论怎样……也不算过分"。"not"可换用"hardly","scarcely"等,"too"可换用"enough","sufficient"等

You cannot be too careful.

◆“否定+but ”结构

在否定词后面的"but",具有"which not","who not","that not",等等否定意义,构成前后的双重否定。可译成"没有……不是"或"……都……"等Nothing is so bad but it might have been worse.

◆“not so…but”和“not such a …but”结构

这两个结构和"否定+but"的结构差不多,不同之点是这两个结构中的"but"是含有"that…not"意味的连续词,表示程度。可译为"还没有……到不能做……的程度","并不是……不……","无论怎样……也不是不能……"等。

He is not so sick but he can come to school.

◆only (not, all, but, never) too …to do so “和”too ready (apt) + to do“结没有否定意义,凡是”not“,”all“ ”but等字后+“too…to,”不定式都失去了否定意义,在“too ready(apt)+to do”结构中也没有否定意义。

You will be but too glad to get home.

◆“cannot…too…”结构

"cannot…too…"意为"It is impossible to overdo…"或者,即"无论怎样……也不算过分"。"not"可换用"hardly","scarcely"等,"too"可换用"enough","sufficient"等

You cannot be too careful.

◆“否定+but ”结构

在否定词后面的"but",具有"which not","who not","that not",等等否定意义,构成前后的双重否定。可译成"没有……不是"或"……都……"等Nothing is so bad but it might have been worse.

◆“not so…but”和“not such a …but”结构

这两个结构和"否定+but"的结构差不多,不同之点是这两个结构中的"but"是含有"that…not"意味的连续词,表示程度。可译为"还没有……到不能做……的程度","并不是……不……","无论怎样……也不是不能……"等。

He is not so sick but he can come to school.

◆“good and …”的副词用法,译为“非常”,“很”等。

类似还有"nice and …", "fine and …," "lovely and …", "bright and …", "rare and …", "big and …"等,均表示程度。

The apples are good and ripe.

◆ "and that"结构,这个"and that"应译为"而且……",表示对它前面陈述部分的语气加强,"that"代表前面的整个陈述部分。

Return to your work , and that at once.

◆“at once…and”结构,这个结构译为“既……又……”,起相关连接的作用,相当于“both…and…”。

The novel is at once pleasing and instructive.

.◆ “in that…”结构,这个结构的意思是“在那一点上(方面)”,可译为“因为”。类似的结构还有“in this…”。

The budget is unrealistic in that it disregards increased costs. 多个形容词的排列顺序:

A, brown, charming, French, oak, old, round, small, writing

desk

A charming small round old brown French oak writing desk

限定词→一般描绘性形容词→表示大小、长短、高低的形容词→表示形状的形容词→表示年龄、新旧的形容词→表示颜色的形容词→表示国籍、地区、出处的形容词→表示物质、材料的形容词→表示用途、类别的形容词→名词中心词。

县长行令杀国才

县(限定词)长(长短)行(形状)令(年龄)杀(颜色)国(国籍)才(材料)

Many, wool, green, Chinese, large, beautiful, carpets

Many beautiful large green Chinese wool carpets

非谓语动词与独立主格:短语,句子(或者句子,短语)

当短语部分有独立主语,并且该主语不同于句子主语,这时短语结构称为独立主格。(它最明显的特点是短语部分有独立的主语)。

独立主格的结构1:名词(代词)+ 分词[现在分词、过去分词]

现在分词表示主动的,正在进行的行为;过去分词表示被动的,已经完成的行为。作题时要通过判断动作与名词(代词)之间的关系来确定是使用现在分词还是过去分词。当动作由名词(代词)发出时使用现在分词,而名词(代词)是受动者时则用过去分词。

1). Silver is the best conductor of electricity, copper _B_ it closely.

A followed

B following

C to follow

D being followed

2). All things _A_, the planned trip will have to be called off.

A considered

B be considered

C considering

D having considered

call off 取消;cancel vt. 取消;四级中的考点就是现在分词和过去分词的区别。

独立主格的结构2:with + 名词(代词)+ 分词[句子当中作状语]

1). After the Arab states won independence, great emphasis was laid on expanding education, with girls as well as boys _C_ to go to school.

A to be encouraged

B been encouraged

C being encouraged

D be encouraged

as well as 和(相当于and);be encouraged不会考。

动词不定式有预示将来行为的含义。to be encouraged 将要被鼓励;

been encouraged 已经被鼓励完了,与主句的谓语动词相对;being encouraged 正在被鼓励

2.短语部分没有独立主语,则短语结构称为非谓语动词。

非谓语动词的结构:分词(分词短语)

句子的主语决定非谓语动词中的分词是用主动还是被动形式。如果是句子的主语发出动作,则使用现在分词;如果动作不是由句子的主语发出,则使用过去分词。2).No matter how frequently _A_, the works of Beethoven always attract large audiences.

A performed

B performing

C to be performed

D being performed

perform vt. 表演,演出,演奏;

to be performed 将要被演奏;being performed 正在被演奏;

倒装:倒装有全部倒装和部分倒装。

谓语部分所有单词都放在主语前是全部倒装。谓语的一部分放在主语的前面是部分倒装。

谓语中的一部分通常是指:1、系动词;2、助动词;3、情态动词。

全部倒装的五条原则:

1. There be句型(表示有);

2. 以There或now开头的句子,且句子谓语动词为come或go;

There you go again. 你又去那里了。

3. 以Here开头的句子,且句子谓语动词为系动词be;Here you are. 拿去。

4. 以副词out, in, up, down, away开头的句子;

在2、3、4前提下,如果句子的主语是代词则用陈述句语序。

5. 以状语(常见的是地点状语)开头的句子。

部分倒装的六条原则:

1. so放在句首时表示承前肯定,这个句子用部分倒装;

nor, neither放在句首时表示承前否定,句子也用部分倒装;

2. 省略了引导词if 的虚拟条件从句,可以把从句中的had, should, could, were中的任何一个提到从句最前面的位置,构成部分倒装;

3. as, though表示“尽管”时引导从句,从句中的表语可以置于引导词之前构成部分倒装;

系动词后面的部分就是表语,形容词、名词、名词性短语可以置于系动词之后。例如:She is beautiful. They are students.

四级考试中出现的是由动词的过去分词转变的形容词作表语的形式。

例:. _B_ as it was at such a time, his work attracted much attention.

A Being published

B Published

C Publishing

D To be published 当题干是as引导一个从句,且as前为一个空格时他表示的就是尽管,空格处要填的就是表语。

being published 正在被出版;to be published 将要被出版。

此句恢复正常语序应为:As it w as published at such a time …

4. 表示否定含义的单词或短语放在句首,句子用部分倒装;

常见的一些表示否定含义的单词:never, little, few, hardly (… when), scarcely (… when) ;

seldom 难得,不常;nowhere 哪里都不。

常见的一些表示否定含义的短语:in no way 决不;on no account 决不;under no circumstances 在任何情况下都不。

5. only + 状语放在句首,句子用部分倒装;(如果only去掉就是全部倒装)例:. Only under special circumstances _C_ to take make-up tests.

A permitted are freshmen

B freshmen are permitted

C are freshmen permitted

D are permitted freshmen

freshmen 新生;make up for 弥补,补偿;make-up tests 补考(缓考)。

6. 注意两个表达形式:come what may 无论发生什么情况;say what you will 畅所欲言。

四级英语知识点总结

四级英语知识点总结 四级英语知识点总结 英语不像汉语可以有固定的形容过去与现在的词语,要想表达不同时间的内容就必须懂得时态的转换。英语中事情发生的时间可分为现在、过去、将来和过去将来四种形式,发生的方式可分为一般、过去、进行和完成进行四种形式。 将时间形式和动作方式结合起来,就构成了以下:一般、完成、进行、完成进行几种时态。下面我们为大家仔细总结了英语中常用的几种时态,希望对大家的考试有所帮助。 现在:现在一般时do、现在完成时have done、现在进行时is doing、现在完成进行时have been doing 过去:过去一般时did、过去完成时had done、过去进行时was doing、过去完成进行时had been doing 将来:将来一般时will do、将来完成时will have done、将来进行时will be doing、将来完成进行时will have been doing、过去将来:过去将来一般时would do、过去将来完成时would have done、过去将来进行时would be doing、过去将来完成进行时would have been doing 英语的时态是靠动词的变化和时间状语来表达的。英语中的时态共有十六种,但是常考的或较常用的只有9种。 要掌握英语的时态和语态,必须掌握好英语中的助动词:第三人称单数:does。

主语+be+v.ing〔现在分词〕形式 They have lived in Beijing for five years. 他们在北京已经住了5年了。 4、一般过去时 表在过去某个特定时间发生且完成的动作,或过去习惯性动作,不强调对现在的影响,只说明过去。常跟明确的过去时间连用,如:yesterday; last week; in 1945, at that time; once; during the war; before; a few days ago be动词+行为动词的过去式,否定句式:在行为动词前加didnt,同时还原行为动词,或waswere+doing+其它 Beijing was hosting the 29th Olympic Games in August 2008. 在20xx年8月,北京正在举行29届奥运会。 6、过去完成时 表示过去某个时间之前已经完成的动作,即过去完成时的动作发生在“过去的过去”,句中有明显的参照动作或时间状语,这种时态从来不孤立使用。 7、一般将来时 表在将来某个时间会发生的动作或情况。常和tomorrow, next year等表示将来的时间状语连用。 am/are/is+going to+do 或will/shall+am/is/are/about to + do 、am/is/are to + do;

Why should you be so late today? 你今天为什么来得这么晚? should有时表示应当做或发生的事,例如: We should help each other.我们应当互相帮助。 我们在使用时要注意以下几点: 1. 用于表示“应该”或“不应该”的概念。此时常指长辈教导或责备晚辈。例如: You should be here with clean hands. 你应该把手洗干净了再来。 2. 用于提出意见劝导别人。例如: You should go to the doctor if you feel ill. 如果你感觉不舒服,你最好去看医生。 3. 用于表示可能性。should的这一用法是考试中常常出现的考点之一。例如: We should arrive by supper time. 我们在晚饭前就能到了。 3) What...? 与 Which...? 1. what 与 which 都是疑问代词,都可以指人或事物,但是what仅用来询问职业。如:What is your father? 你父亲是干什么的? 该句相当于: What does your father do?

The football game comes to you from New Y ork. (2002.01) A) live B) lively C) alive D) living 解题小贴士 1. 【C】 选项中有affect,effect,出题者正是看中了我们对这两个单词的认知度不够。affect 意为“影响”(verb);effect意为“结果,作用,影响”(noun);lessen意为“减少,减轻”;decline意为“下倾,下降”。正确答案为C,题目译文为:“评论家们认为被大量广告控制的电视已经影响了节目的质量。” 2. 【D】 在英语中一个单词的形容词形式有很多变形,稍不注意,我们就很容易被它们搞糊涂,千万别掉进陷阱了哟!sense意为“见识,感觉”,加-tive表示具感觉性质的,意为“敏感的”,引申意为“灵敏的,感光的”;加-able后意为“能够感到的,有意识的,明智的,有判断力的”;flexible意为“灵活的,柔软的”;objective意为“客观的,公正的”。所以正确答案为D,题目译文为:“有些植物对光特别敏感,它们喜欢荫凉处。” 3. 【D】 edition表“版本”,paper covered edition平装本,hard copy edition精装本;editorial 表“编辑的”;article表“文章,论文”;abstract表“摘要”。按题目意思来看,只有“摘要”才会是200字的。所以正确答案为D,题目译文为:“作者不得不随他的研究论文交一份200字的摘要。” 4. 【A】 这一题的考点在adapt和adopt上,有些考生很难在短时间内区分出其意思,尤其是放在一起时。前者意为“适应,改编”,adapt to new conditions适应新环境;后者中间为“o”,让我们想到son,boy,所以意为“收养,采用”,adopt skills采用技巧,adopt children 收养孩子;stick表“粘住,粘贴”;yield表“出产,(~to)屈服”。正确答案为A,题目译文为:“IBM的竞争对手是否能够以合适的成本使他们的产品去适应新的硬件,这件事情现在说还为时尚早。” 5. 【A】 这几个单词都是live的形容词,A中live是我们经常在电视的右上角看到的,表示“实况转播”。B中的lively虽以-ly结尾,但不是副词,而是形容词,表示“活泼的,真实
