If和unless的用法

If的用法:1. (表示条件)如果,

例如:He will come if you invite him.

2. (表示虚拟)假如,要是

例如:If they were here, they would help you.

If she had worked harder, she would have succeeded.

If you succeeded, everything would be all right.

3. 是否= whether 连接宾语从句

unless的用法:unless 是从属连词,常用来引导一个条件状语从句, 由于其本身具有否定的意义,所以其引导的从句就不再用否定词了.

另外, unless引导的条件状语从句仍像if引导的条件句那样,用一般现在时表示将来.例如:I'll not go there unless I'm invited. 除非受到邀请,要不然我就不去那儿。

它们的区别在于:1、不能用and连接两个unless从句,即不能用…unless…,and unless…。但if…not and if…not却不受此限。

2、unless不可用于虚拟条件,if则可以。

形容词的用法

一、形容词(组)用作状语,常常表示伴随情况。可以放在句首,也可放在句末。例如:

2.Easy to be with,he is warmly welcomed.——因为平易近人,所以他受到热烈欢迎。

三、形容词(组)用作结果状语,一般位于句末。例如:

1.They broke into the uncle?s bedro om and found the man lying on the floor,dead.

1.Even more important,he is in charge of the project.——更重要的是,他负责这项工程。

2.Curious,the game should turn out that way.——真奇怪,比赛结果是那样的。

五、形容词(组)用作让步状语,常由一个形容词短语或or连接的两个以上的并列形容词短语构成。常常位于句首也可位于句中。例如:

2. Every nation, big or small, should be equal.——每个国家无论大小,都应一律平等。

比较

1(not) as …as 表示在某一点上两事物(不)相同

as…as 之间必须用形容词或副词的原级

The boy looks like his father.

I’ll do as you advise.

3the same as 用于说明某事物与另一个一样.

I’m not the same height as my brother.

We have lived in this same house for thirty years.

same 前面必须有定冠词the,后加单数名词

different 正好相反,前面不用加the,后面用复数名词

We study in the same school, but in different classes.

There are different books on the same subject.

Note: 但也可以说a different 加单数名词

This is a different girl from the one I saw just now.

目的状语从句:

从句部分是用以补充说明主句中谓语动词发生的目的的。

表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导;

目的状语从句的谓语常含有may, might, can, could, should, would等情态动词。

例如:

You must speak louder so that /in order that you can be heard by all.

He wrote the name down for fear that(lest) he should forget it.

Better take more clothes in case the weather is cold.

引导目的状语从句常用的连词有:that(以便),so that(以便),in order that(为了;以便),Lest(免得;唯恐),for fear that(生怕;以免)。

【例如】

Say it louder(so)that everyone can hear you.

大声说,以便大家都能听到你。

I am telling you that lest you should make a mistake.

我告诉你这一点,以免你搞错。

学习目的状语从句应注意以下两点:

(1)目的状语从句中常含有can,could,may,might,should等情态动词。

【例】

I got up early so that I could catch the first bus.

我起得很早,目的是为了赶上头班公共汽车。

(2)在口语中so可以引导目的状语从句。

【例】

We'll sit nearer the front so we can hear better.

我们坐的靠前一点,因此,我们听得清楚一点。

【注意】in order that与in order to的区别:

in order that+从句

in order to+动词原形(in order to后面加的那个不叫目的状语从句,叫目的状语)

目的状语从句的一个特点:由于目的都是未来的行为,

所以从句中一般用表示未来可能性时态,比如上面两句中的could。

当然还可以用will,would,can,等

结果状语从句的连词

以下结果状语从句的一些用法。

1) so … that…/ such ….that

该句式中重要考查的是so和such的区别。应注意以下可能出现的结构:

so nice a boy that…

such a nice boy that…

so beautiful/diligent/carefully … that…

such (fine weather/great improvement) that…

2) so that

Everyone lend a hand, so that the sowing was done in time.

该句式中主要考查so that 与其它短语的区别,如:

I took no notice of him, ___ he flew into a rage.

A.for that

B.so that

C.in that

D.but that

由于so that也可以引导目的状语从句,同学们应特别注意从句中时态的运用。

3) so much so that

该结构用于形容词或副词之后,表示"到如此程度以致于"。如:

He was very weak, so much so that he could not walk.

I long to visit Beijing, so much so that I dream about it every night.

4) 注意结构状语从句与too….to..enough to…, so… as to结构的不同。

结果状语从句

结果状语从句常由so… that 或such…that引导,掌握这两个句型,首先要了解so 和suc h与其后的词的搭配规律。

比较:so和such

其规律由so与such的不同词性决定。such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词。so 还可与表示数量的形容词many, few, much, little连用,形成固定搭配。

so foolish such a fool

so nice a flower such a nice flower

so many / few flowers such nice flowers

so much / little money. such rapid progress

so many people such a lot of people

(so many 已成固定搭配,a lot of 虽相当于many,但 a lot of 为名词性的,只能用s uch搭配。)

so…that与such…that之间的转换既为so与such之间的转换。

The boy is so young that he can't go to school.

He is such a young boy that he can't go to school

让步状语从句

让步状语从句是状语从句中的一种,其本身也是状语从句。

一般翻译为“尽管……即使……”就是我们日常生活中用的“退一步说……”的感觉。

引导让步状语从句的连词主要有以下这些:though, although, as; even if, even though; whether...or...; no matter+疑问词,疑问词-ever。下面对这些连词引导的让步状语从句作一说明。

(1)though, although表示“虽然,纵然”之意。

这两个连词意思大致相同,在一般情况下可以互换使用。在口语中,though较常使用,altho ugh比though正式,二者都可与yet, still或nevertheless连用,但不能与but连用。例如:Although/Though he was worn out, (still) he kept on working. 虽然他已经精疲力竭了,但仍然继续工作。

Although/Though he is very old, (yet) he is quite strong. 他虽然年纪大了,身体还很健壮。

值得注意的是,although引导的让步状语从句位于主句之前的情况较多,though引导的让步状语从句可位于主句之前或主句之后。例如:

She passed the examination though she had not studied very hard. 她虽然不用功学习,考试却及格了。

(2)as, though表示“虽然……但是”,“纵使……”之意。

as引导的让步状语从句必须以部分倒装的形式出现,被倒装的部分可以是表语、状语或动词原形,though间或也用于这样的结构中,但although不可以这样用。例如:

Object as you may, I?ll go.(=Though/Although you may object, I?ll go.) 纵使你反对,我也要去。

Hard as/ though he works, he makes little progress. (=Though he works hard, he makes little progress.)尽管他学习很努力,但几乎没取得什么进步。

Child as/though he was, he knew what was the right thing to do.(=Though he was a child, he knew what was the right thing to do.)虽然他是一个孩子,但他知道该做什么。

Fast as you read, you can?t finish the book so soon. 纵然你读得快,你也不能这么快读完这本书。

让步状语从句表示:虽然,尽管,即使等概念,由although(尽管), though(尽管), how ever(无论怎样), whatever(无论什么), whoever(无论谁), whomever(无论谁), which ever(无论哪个), whenever(无论何时), wherever(无论哪里), whether(是否), no mat ter (who, what, where, when, etc) (无论……), even if(即使), even though(即使)等词引导。

如:We won?t be discouraged even if(=even though) we fail ten times.我们就是失败十次也不泄气。

It was an exciting game, though / although no goals were scored.那是一场精彩的球赛,尽管一个球都没进。(though, although不能与but连用)

Whether you believe it or not, it?s true.不管你信不信,这是真的。

However (=No matter how) expensive it may be, I?ll take it.无论它有多贵,我也要买下它。

Don?t let them in, whoever(=no matter who) they are.不管他们是谁,别让他们进来。

No matter what I say or how I say it, he always thinks I?m wrong.无论我说什么或怎么说,他总认为是我错。

特别提醒

.用though/although, as 引导让步状语从句时,句中不能用but表示转折语气。

不能说:Though he looks weak, but he is healthy.

而要说:Though he looks weak, he is healthy.

或者说:He looks weak, but he is healthy.

过去进行时

概念

表示过去某时正在进行的动作(不强调是否完成)。(过去进行时具体用在什么地方,看后面)

过去进行时的主要用法

1.表示过去某一时间内(正在)进行的动作

如:I was doing my homework at 9 p.m. last Sunday.

2.表示一动作正在进行时,另一动作同时正在进行.

(1)用while连接(while只接doing)

例:My mother was cooking while I was doing my homework.(可以持续动作时态一致) (2)when表示(when可以接doing或did,when后动作时间长,用doing,时间短,用di d)

例:I was doing my homework when my mother came in.(间接表达了具体时间)

3.重复的动作

定语从句

.定语从句:定语从句是由关系代词或关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,相当于形容词,所以又称为形容词性从句,一般紧跟在它所修饰的先行词后面。

2.关系词:引导定语从句的关联词称为关系词,关系词有关系代词和关系副词。关系代词有t hat, which, who, whom, whose, as等;关系副词有where, when, why等。关系词常有3个作用:1,引导定语从句。2,代替先行词。3,在定语从句中担当一个成分。

注:关系代词有主语.宾语之分。一般whom作为宾语。

4.定语:定语用来限定、修饰名词或代词的,是对名词或代词起修饰、限定作用的词、短语或句子,汉语中常用………的?表示。主要由形容词担任。此外,名词,代词,数词,分词,副词,不定式以及介词短语也可以来担任,也可以由一个句子来担任.单词作定语时通常放在它所修饰的词之前,作前置定语。短语和从句作定语时则放在所修饰的词之后,作后置定语。

(一)限定性定语从句

一、关系代词(在句中作主语、宾语或定语)

1. that既可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语也可以省略。[eg:this is the book (wh ich)you want。]而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置

2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢

3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括当先行词是anything, everything, nothing , none等不定代词时,或者是由every, any, all, some, n o, little, few, much等修饰时等,这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that

4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语

5. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与of which 调换,表达的意思一样。

二、关系副词(在句中作状语)

关系副词=介词+关系代词

why=for which

where=in/ at/ on/ ... which (介词同先行词搭配)

when=during/ on/ in/ ... which (介词同先行词搭配)

1. where是关系副词,用来表示地点的定语从句。

2. when引导定语从句表示时间[注]值得一提的是,表示时间“time"一词的定语从句只用w hen引导,有时不用任何关系代词,当然也不用that引导。

By the time you arrive in London, we will have stayed there for two weeks. I still r emember the first time I met her. Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。

3. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anythi ng, everything或nothing时,常用there is来引导

There is somebody here who wants to speak to you. 这里有人要和你说话。

(二)非限定性定语从句

非限定性定语从句的作用是对所修饰的成分作进一步说明,通常是引导词和先行词之间用逗号隔开,将从句拿掉后其他部分仍可成立

1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分

2.当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如:

Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了,他曾经是我的老师。

My house, which I bought last year, has got a lovely garden.我去年买的的那幢房

子带着个漂亮的花园。

This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍。

3.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第

三人称单数,例如:

He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦。

Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发。

4. 有时as也可用作关系代词

5. 在非限定性定语从句中,不能用关系副词why和关系代词that,而用who, whom代表人,用which,whose代表事物.;

(三)关系代词引导的定语从句

1.who指人在从句中做主语

(1) The boys who are playing football are from Class One.

(2) Yesterday I helped an old man who lost his way.

2. whom指人,在定语从句中充当宾语,常可省略。(注:who和whom已无太大区别,可以通用。)

(1) Mr. Liu is the person (whom) you talked about on the bus.

(2) Mr. Ling is just the boy whom I want to see.

(3) The man who/whom you met just now is my friend.

注意:关系代词whom在口语和非正式语体中常用who代替,可省略。

如果在从句中做宾语,就用whom或who.比如: He is the man whom/who I talk to.

如果是在从句中作主语就只能用who.比如: He is the man who has an English book.

3.which指物,在定语从句中做主语或者宾语,做宾语时可省略

(1) Football is a game which is liked by most boys.

(2) This is the pen (which) he bought yesterday.

4. that指人时,相当于who或者whom;指物时,相当于which。

在定语从句中做主语或者宾语,做宾语时可省略。

(5) The number of the people that/who come to visit the city each year rises one million.

(6) Where is the man that/whom I saw this morning?

5. whose通常指人,也可指物,在定语从句中做定语

(1) He has a friend whose father is a doctor.

(2) I once lived in a house whose roof has fallen in.whose指物时,常用以下结构来代替

(3) The classroom whose door is broken will soon be repaired.

(4) The classroom the door of which is broken will soon be repaired.

(5) Do you like the book whose color is yellow?

(6) Do you like the book the color of which is yellow?

(四)注意

介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时

从句常由介词+关系代词引导

(1) The school (that/which) he once studied in is very famous.

(2) The school in which he once studied is very famous.

(3) Tomorrow I will bring here a magazine (that/which) you asked for.

(4) Tomorrow I will bring here a magazine for which you asked.

(5) We?ll go to hear the famous singer (whom/that/who) we have often talked about.

(6) We?ll go to hear the famous singer about whom we have often tal ked.

注意:1. 含有介词的动词短语一般不拆开使用,如:look for, look after, take care of等

(1) This is the watch which/that I am looking for. (T=正确)

(2) This is the watch for which I am looking. (F=错误)

2. 若介词放在关系代词前,关系代词指人时用whom,不可用who或者that;指物时用whi ch,不能用that;关系代词是所有格时用whose

(1) The man with whom you talked is my friend. (T)

(2) The man with that you talked is my friend. (F)

(3) The plane in which we flew to Canada is very comfortable. (T)

(4) The plane in that we flew in to Canada is very comfortable. (F)

3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词

(1) He loved his parents deeply, both of whom are very kind to him.

(2) In the basket there are quite many apples, some of which have gone bad.

(3) There are forty students in our class in all, most of whom are from big cities.

直接引语

引用别人的话有两种方式,一种是讲述别人的原话,并把它放在括号里,这叫直接引语;另一种是用自己的话来转述别人,并且不能用引号,这就是间接引语。直接引语[1]和间接引语之间可以互相转换。

She said "My brother doesn't want to go there." [直接引语]

她说:“我哥哥不想去那儿。”

→She said that her brother didn't wan t to go there.[间接引语]

He said to her, "I'll help your brother with his English."[直接引语]

他对她说:“我将帮你弟弟学英语。”

→He told her that he'd help her brother with his English.

直接引语变间接引语的五点变化

1.时态变化

直接引语变为间接引语时,若主句为过去事态,变为间接引语的宾语从句的时态如下表:

eg:

"l like English very much,"he said.

他说:“我很喜欢英语。”

→He said that he liked English very much.

He said, "It would rain soon."

他说:“很快就会下雨。”

→He said that it would rain soon.

注意:

[1] 若直接引语为客观真理,则变为间接引语时事态不变:

The teacher said to us,"Knowledge is power."老师对我们说:“知识就是力量”

→The teacher told us that knowledge is power.

[2]有时由于直接引语有特定的过去时态状语,变为间接引语时时态也可不变:

He said that his daughter was born in 1997."他说:“我的女儿是1997年出生的。”

→He said that his daughter was born in 1997.

2.时间状语的变化

直接引语变为间接引语时,有些时间状语也要作相应的变动。

eg:

He said,"l'm sleeping now ."他说:“我现在在睡觉。”

→He said that he was sleeping then.

各类句子由直接引语变间接引语的方法 1.当直接引语为陈述句时,变为间接引语的方法是:将直接引语变为由that引导的宾语从句,跟在引述的动词之后(that也可以省略)。eg: She said :"My sister doesn't want to come here."她说:“我妹妹不愿意来这。”

→She said that her sister didn't want to go there .

2.当直接引语为一般疑问句时,变间接引语的方法:将直接引语变为由if 或whether 引导的宾语从句跟在叙述动词之后。eg:

"ls everybody here?"the teacher asked.老师问道:“大家都到齐了么?”

→The teacher asked if/ whether everbody was there.

3.当直接引语为特殊疑问句时,变为间接引语的方法是:将直接引语变为由“疑问词”引导的宾语从句,跟在引述之后。eg:

She asked ,:"Where does he live?“ 她问:“你住在哪里?”

→She asked where he lived.

4.当直接引语为祈使句时,变为间接引语的方法是:使用ask / tell / order sb. to do st

h. 这一结构进行转换,若祈使句为否定式则用ask / tell / order sb. to do sth., 其中ask, t ell, order 的选择要根据句子的语气而定。eg:

"Get up early tomorrow , Bill,"he said. 他说:“比尔,明天早点起床。”

→He told Bill to get up early the next day.

5.直接引语如果是感叹句,改为间接引语时,改成用疑问代词what或疑问副词how引导的宾语从句。也可以改为that引导的从句。e.g.

He said to me ,"What a beautiful park it is."

→ He told me what a beautiful park it was.

或He told me that the park was quite beautiful.
