代词

非谓语动词

从句（引导词加句子）

Handsome and strong are his nature

Handsomeness and strength are his nature

Being handsome and strong is his nature

主语能不能少

如果没有主语

加 it 作为主语：必须和天气、温度、时间有关系

It is hot outside

It keeps raining

there be 句型：意思中包含“有”字

There exist a host of undergraduates being fascinated with me

Ther are numerous factors accounting for(explicating, explaining) my perspective

形容词

介词短语

example

I smile on the stage （主谓结构）

I exchange with my watch（及物动词后面必须有宾语，缺少宾语）

应用

写作

所有写不来的长难句暂时都写成简单句，一定要保证语法正确

长难句

第一步找动词，也就是谓语，从而找到一句话的主谓宾

如果一句话当中找到多个动词，确定主句的那个动词（主句动词前面没有引导词）

并列句

什么是并列句？

就是用连词连接两个句子

常见并列连词

平行关系

and

not only...but also...

副词或介词短语：similarly, equally, likewise, at the same time, in the mean while

转折关系

but

yet

while

whereas

副词或介词短语：however, nervertheless, conversely, on the contrary, unexpectedly, unfortunately

选择关系

or

whether...or...

副词或介词短语：alternatively

因果关系

for

so

副词或介词短语：therefore, thus, consequently, as a result

递进关系

then

副词或介词短语：besides, furthermore, moreover, additionally, subsequently, in addition

规则

使用连词时，两句话之间的逗号可有可无。

使用非连词逻辑关系词时，不能连接两个句子，要么中间要是句号，要么加 and 连接

应用

写作

主要写作的上下句之间有逻辑关系就一定要用逻辑关系词（连词、副词、介词和介词短语）

example

有朋自远方来，不亦乐乎：There remain a host of companies coming from afar(the distance), and consequently I feel more than delighted.

完型

只需要读懂逻辑关系词前后两句话的意思就可以了

长难句分析

只要有并列连词的出现，通常都会有省略，翻译的时候先把省略补上

分析长难句的第二步是找连词，但是连词连接两个单词的时候直接无视

如何查找省略的内容

省略一定发生在连词后

连词后面有的成分连词前面通常有，如果连词后只有一个成分的时候前面必然能找到对应成分

连词前面有而连词后面没有的成分就是省略的内容

example

I was beaten and you

名词性从句

名词可作为

主语：The movie looks terrific

宾语：I admire his mother

表语：Gump is a man

同位语：I enjoy the part, the beginning

同位语（同样位置）-用来解释名词的成分就是同位语

I, a university student, like Eason, A well-know singer from Hongkong.

My mother, a typical housewife, enjoy palying Mahjong, a chinese entertainment.

在作文中只要见到名词就可以考虑加同位语对该名词进行补充说明

Persistent, an active mentality, plays a critical role in the glories of all children and adults

可作为同位语的成分

名词

代词

非谓语动词：I enjoy the sports, running.

从句

什么是名词性从句

主语从句：What I saw looks terrific

宾语从句：I admire his mother what she said

表语从句：Gump is who we should learn from

同位语从句：I enjoy the part that a bird is flying in sky (从句做同位语没有逗号）

名词在句子中充当的成分，从句都能充当，这就是名词性从句

名词性从句的引导词

He has got divorce is my fault

That he has got divorce is my fault

Has he got divorce is obvious

Whether he has got divorce is obvious

Who will he marry is a secret

Who he will marry is a secret

名词性从句引导词按照从句类型分类

that：陈述句，不充当成分，也没有意思

whether：一般疑问句，不充当成分，表示“是否”的意思

所有的特殊疑问词：特殊疑问句，疑问词

所有的从句都是陈述句形式，引导词+主语+谓语

example

I am wondering whether aliens exist （我想知道外星人是否存在）

That ladies tend to be right remains common knowledge （女人总是对的，这是一个常识）

My meaning seems that supporting the elderly remains a Chinese tradition(conventional) virtue （我的意思是孝敬父母是中国的传统美德）

Someday, one will perceive that career, kinship and friendship are(prove) more indispensable than romance （有一天你会发现事业、情亲和友情比爱情更重要）that 引导的宾语从句

The point is(seems) when wealth will become avaliable for you （关键是你什么时候有线）

应用

主句从句满分句型

It……that……（it 做形式主语，把主语从句放到后面）

It is apparent that……

It looks beyond dispute that……

It has been widely accepted that……

It is universally acknowledged that……

众所周知/显而易见

It keep my argument that…… （我认为……）

可以写在作文中任何一句话的前面

example

It looks beyond dispute that the issue about diligence has been brought into the limelight （显然关于勤奋的话题已经引起了广泛的关注）

同位语从句满分句型

The matter that he managed to find a girlfriend makes his superiors rejoiced（他找到了女朋友使得他父母很高兴）

The matter makes his superiors rejoiced that he managed to find a girlfriend （同位语从句放在句末）

Nothing can hide the truth that she is getting old （没有什么事能掩盖她在变老的事实）

The outlook proves wrong that private individuals in HeNan are(seem) all deceivers （河南人都是骗子这种想法是不正确的）

The evidence that flowers in the greenhouse fail to undergo storms indicate that childrens should by no means be spoiled by their sensor citizens（温室里的花朵不能经受风雨这个事实表明我们不应该溺爱孩子）

长难句分析

主语从句

只要见到有引导词在句首并且从句没有被逗号隔开，一定是主语从句。主语从句从名词后开始到主句的谓语动词结束；见到 It...that... 通常都是主语从句，到句末结束

宾语从句

只要实义动词后有一个引导词，就暂定为宾语从句，状语从句也有可能

宾语从句的 that 可以省略

She said (that) she would marry an old rich man

宾语从句中的“是否”可以写 if

I wonder if I can pass National Postgraduate Entrance Examination smoothly

it 做形式宾语

I find it pleasant to be with him

We think it pity that the party was canceled

We must make it clear that authorities involved are to spare no effort to curb the phenomenon of abusing kids

表语从句

只要系动词的后面有一个引导词就是表语从句

同位语从句

只要名词后面有一个引导词就暂定为同位语从句，更可能是定语从句

定语从句（形容词性从句）

定语是用来修饰、限定、说明名词或代词的成分

成分

形容词

The navie nightgale died

名词（短语）

The singing of nightgale can make the rose bloom

介词短语

The nightgale out of window heard the sighs of the youngster

非谓语动词

The singing nightgale lost his life

从句

定语的位置

前小后大：当一个单词修饰时通常放在名词前，多个单词时通常放在名词后

This is a fiction about a nightgale and a rose

The youngster grasping romance left the party of the prince

The boy rejected looks pitiful

过去分词修饰名词时，通常放在名词后

I have something important to tell you

当形容词修饰不定代词时，通常放在名词后

定语从句的引导词

先行词：被定语从句修饰的名词、代词

1.当先行词是人：who whom whose

2.当先行词是物： that which whose

3.当先行词是时间：that which when

4.当先行词是地点： that which where

5.当先行词是原因： that which why

引导词的选择

看先行词

引导词在从句中能够充当的成分

先行词是时间，从句完整：I will never forget the day when I met you. （when作副词）

先行词是时间，从句缺宾语：I will never forget the day that we spent. （that 作代词）

先行词是原因，从句完整：You had batter have some reason why you are late. （why作副词）

先行词是原因，从句缺主语：You had batter have some reason that sound perfect. （that 作代词）

新分类标准

代词（在从句中一定要充当主语或宾语的成分）：who whom that which

副词（在从句中不能充当任何主干成分）：where when why

形容词（在从句中修饰离它最近的名词）：whose

examples

The rose that nightgale exchanged with his life was discard. （定语从句）

Buildings whose roofs are round look beautiful （定语从句）

it has been validated by numerous(countless) facts that glories(success) belong to those with dreams（成功属于有梦想的人已经被无数的事实证明） （主语从句）

wearing my own shoes not only proves convenient but also ensures a point that the feelings of others can be ingored. （穿自己的鞋不仅方便而且可以保证一点，不用关心别人的感受）（同位语从句）

The key of the issue is(seems) who should be responsible for decline of moral(ethics) （表语从句）

He whose appearence looks indecent(sloppy) is(proves) noble in his mind （定语从句）

It is crucial that those who spare no efforts to realize their dreams never feel regretful although glories fail to be achieved.

Students who fail to concentrate in class but wish to pass examinations smoothly trend to find that the consequence proves less impressive

特殊用法

that 在引导定语从句的时候，如果 that 充当宾语，that 可以省略

I enjoy the book that my ma bought for me. （如果见到两个名词或代词直接放到一起，中间没有标点或连词隔开，通常都是省略了 that 的定语从句）

限制性与非限制性定语从句

限制性定语从句：对先行词起限定作用，没有它，先行词的意义或身份就不明确，所以它在句中必不可少

非限制性定语从句：对先行词起解释或补充说明的作用，前后有逗号与主句隔开，可有可无

先行词和引导词之间有介词的情况

人只能用 whom ： He is the man from whom we should learn

物只能用 which：I will never forget the day on which I meet you

the same ... as 与 the same ... that 引导的定语从句

He is the same man as I love （as 译作“像”）

He is the same man that I love （that 译作“是”）

as 和 which 引导的非限制性定语从句

which 引导的非限制性定语从句可以修饰前面整个句子（也就是先行词是整个句子），as 也可以，但是 which 只能放在主句的后面，as 则可前可后

He enjoys talking with young ladies, which drives me mad

引导词 that 和 which 的区别

不重要

定语从句与同位语从句的区别

①对名词的修饰 ②that 在从句中充当成分 ③先行词可以是所有名词 ④引导词有 8 个

I have a dream that sounds funny. （定语从句）

①对名词的解释 ②that 在从句中不充当成分 ③先行词只能是抽象名词 ④引导词一般是 that

I have a dream that I will become a rich lady. （同位语从句）

定语从句的难点：寻找先行词

是从句前最近的名词

是从句前并列的几个名词

For workers it can mean an end to the security, benefits and sense of importance that came from being a loyal employee.

是从句前面的一个从句

The Greek assumed that the structure of language had some connections with the process of though, which took root in Europe long before people realized how diverse language could be.

是从句前面的整个句子

My husband enjoy talking with other young ladies, which really gets me go mad.

应用

写作

在作文中见到名词都可以有意识的加上定语成分

Pets can reduce loneliness

Pets which look cute as well as healthy can reduce loneliness of citizens and children who stay at home alone.

Reading books can add knowledge.

Reading books which keep beneficial to our physical and mental health can add knowledge of all children and adults

短句写成长句

WuZhen is a water town in ZJ province, locating near the river from BJ to HZ. （独立主格）

WuZhen which locates near the river from BJ to HZ is a water town in ZJ province. （从句）

Doors will be decorated by couplets whose topics are involved in health, wealth and good luck.

长难句

找定语

只要名词后面有一堆不是动词的东西就暂定为修饰这个名词的定语成分，定语从名词后开始到主句的下一个成分结束。一个大定语中通常会有多个小定语，每一个小定语到下一个名词后结束

Some of these cause are completely reasonable results of social needs. Other are reasonable consequences of particular advances in science being to some extent self-accelerating.

Whether to use tests, other kinds of information or both in particular situation depends, therefore, upon the evidence from experience concerning comparative validity and upon such factors as costs and avaliability.

状语从句

形容词和副词充当的成分

形容词

系动词后面作表语

名词前面作定语

副词

修饰实义动词

he cried sadly

修饰形容词，作

he looks especially sad

修饰副词

he cried rather sadly

副词修饰整个句子

actually, he cries

副词无论放在哪都是作状语

什么是状语

状语是在一个句子中，用来修饰实义动词、形容词、副词或整个句子的成分（除了名词不能修饰，什么成分都可以修饰）

状语的成分

副词

She smiles sweetly

介词短语

He run fast like a crazy dog

非谓语动词

She cried, sitting there

从句

She cried when she sat there

状语的位置

位置可以随便放

按照引导词本身意思分类

时间状语从句

引导词

since（译作“自从”）

主句必须用现在完成时态 I have fallen in love with you since I met you.

the moment = as soon as（译作“一……就……”）

by the time （译作“到……为止”）

until

not……until

时态问题

在所有的状语从句中，如果主句的动作和从句的动作都尚未发生的话，主句用一般将来时，从句用一般现在时表示将来（即主将从现）

尚未发生：When love comes, I will hold her hands.

已经发生过了，该用什么时态就用什么时态：When love came, I failed to hold her hands.

区别 until 和 not …… until

主句的动词是延续性动词，用 until ：I will wait here until you come.

主句的动词是瞬间动词，用 not …… until ：I will not leave until you come.

I did not realize the greatness of mothers until I grew up.

when 引导的时间状语从句省略的情况

如果主句的主语和从句的主语一致，并且从句的谓语中有 be 动词，此时从句的主语和be 动词可以同时省略：when I was a kid, I enjoyed singing song.

地点状语从句

引导词

where

The kind of trees grow well in moist place.

You are more beautiful than I am beautiful

应用

写作

作文中任何一句话都可以加一个状语把句子拉长

One can live as if he were a pig. Conversely, he can never be as delighted as a pig.

长难句

要能够快速识别一句话中的状语成分，且能通顺翻译出来

只要在句子中见到副词、比较、条件、结果、原因、让步、目的、方式、伴随就一定是状语

见到名词+时间/地点区别

如果无法确定是定语还是状语遵循定语优先原则

example

Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the reasoned, orderly, systematic, and dispassioned manner that natural scientist use for the study of natural phenomena.
