张家港英语培训_公共英语三级考试需牢记10大项原则
主谓搭配一致原则
1、划线错通常在
is/are/was/were/has been/havebeen/has/have/do/does，动词的第三人称单数。
Feel当“感觉起来”的意思，类似于are。feel like。
动词的单数加“s、es”，名词的复数加 “s、es”
2、如果两个名词只有一个限定词The，那么后面的谓语动词应该是单数形式。
The singer and dancer is….翻译成“兼”
3、one of作主语是后面的谓语动词通常用单数。
One of the people is….
Everyone和does连用
4、复数分子和分母+名词时，谓语动词与分子分母没有关系，和后面的名词形式有关。
Three fifths the books are….后面的谓语动词用复数形式。
Three fifths the book is….
A pair of/a kind of等后面加名词时，谓语动词常用单数形式。
A pair of glasses is missing.主语是pair，眼镜的一副。
A number of=many许多
A number of books ara
The number of books is
The number of….的数量
5、A as well as B 主语是A
6、倒装+主谓搭配一致原则
强调原则
1、It is/was……that
W (which/what/whose/where/when….)给括号里面的就是错误的。
倒装原则
Only/never/not /neither/so/…..+谓语动词，紧跟的动词基本都是错误的。
At on time
under no circumstances
by no means
at no time =never
at no rete
on no account
含not 的介词短语
in no time=soon
In no time can he admit his mistake.应用成at no time.
Only+状语(状语从句)是主句要倒装的。套连词的都是从句，找主句动词那是错的。
Only yeasterday did he tell me everything.
Have、has、had后有过去分词，才能进行疑问、倒装、否定，没有过去分词，要借助其他词。
She has left，so has he?
She has three sister，so do I.
并列原则
And/than/either….or…/neither…nor…/thesameas/but
如果并列没有错，连词本身有错。前后并列词要相同，左右前后要一致，出错基本都在后面的词。并列有时没出现连词，要看句子、标点等。
反义疑问句
前面肯定，后面否定，前面否定，后面肯定
It is hot, isn’t it?
It is hot, is it?
He seldom sleep late, does he?他从不睡觉很晚
祈使句、反义疑问句用will
两种特殊
Let us sit down, will you?
Let’s sit down, shall we?
祈使句固定的will you?
Sit down, will you?
Don’t smoke, will you?
主语有含宾语从句，宾语从句进行反义疑问。
A side B did sth,didn’t B?
He said you were late, weren’t you?
否定词原则
Not/never/hardly/seldom….
若句子中出现两个或两个以上的否定词，则找划线的否定词有可能错。
too：是肯定句的“也”。I like red，me too.
either：是否定句的“也”。I won’t like red，me either.
either：两者中的任何一个都。Either of them，all right. 当代词用。
either：或者或者。Either….or…
三个重要的作用：
否定词在句首要倒装，紧挨着否定词的动词基本都是错误的。
句子中出现否定词，就是否定句，反义疑问句要用可定。
挑错题中出现两个或两个以上的否定词，被划线的否定词是错误的。
时态和语态
考完成时，现在完成时、过去完成时、一般现在时。
1、一般现在时
主将从现原则：在when/before/after/until/as soon as/if/unless等引导的时间或条件状语从句中，主将从现。从句中不能够出现will。
If it is fine tomrrow,I climb the hill. If做“如果”，后面不能出现将来时。
感官动词不能用现在进行时，要用一般现在时。
look、sound、taste
smell、feel
2、现在完成时
Since…
has/have done sth
induring/overthepast/lastfiveyears/days/weeks
in during last five years
during the past….has/have done
3、过去完成时，过去的过去
had done
he side he had done…..
I thought he had left
4、一般过去时
yesterday、ago这些词出现，和did连用
what did you do yesterday?
After和一般时态连用。
5、主动、被动
不及物动词没有被动语态。eat、sleep、play、fail
have you noticed her coat is wet?she must be caught in the rain.
must have been，肯定已经被
must be一般现在时态。表示肯定经常是，肯定经常被，肯定将要是，肯定将要被。
比较级
两者之间比较 far/by far/much/still/even等表示“非常”，后加比较级，表示非常的多。前后要并列平行。
much taller
很长形容词、副词用more，不再用er
两个事物不能出现级，两者用比较，三者用。
虚拟语气
If had done….,would/could/might have done.
If you had come earlier yeasterday,you would have met her.
Had done…,would have done.
Had you come earlier yeasterday,you would have met her.
would have done…..,but+过去时
He would have gone abroad,but he was poor then.
Wished that sb had done
Would rather / it is about time…+sb did sth
But for air and water,there wouldn’t be life. 一贯事实相反，主句要用would be/would do，一般都是空气、阳光、水
But for you help,I would not have succeeded. 过去事实相反，主句用would have done
从句原则
名词+wh-(which/who/whom/when/where/why/whose…)+句子
从句连词被划线了，基本都是错的，尤其是连词which。
非限定定语从句逗号后不能写that，两句话中要有连词。
Lest=for fear that=in case 唯恐，固定连词，后面出现情态助动词，都是should，翻译成“唯恐…万一”。
红皮书 同位从句 后面用that
since 有两个意思：自从，既然
since后面是一般现在时的句子，翻译成“既然”。
如果是一般过去时，就是翻译成“自从”。
Since=now that
