北京四中 毕勤
一、语法知识
(一), 并列连词
1, and连接语法作用相同的部分.
Let me know what
you saw and heard in Europe.
如果连接的两个名词是指同一个人而有两种身份时,第二个名词前不要加冠词或所有格.
Her husband is a
singer and songwriter.
祈使句+and代替条件句.
Work hard and you
will pass the examination.
(1) 由and连接的两个单数名词(2)and前面的主语
之前有every, each, no,
many a的时候用单数谓语动词.
Every train and bus
was crowded with many people.
2, both+主语+and+主语+"复数谓语动词"
Both Tom and Jerry
are going to the cinema.
3, not
only…but (also)如果连接两个主语,谓语动词临近原则.
Not only he but
also his parents are very kind to me.
4, as
well as后面的主语不作为成分.
This study, as well
as many other reports, shows that cancer can be cured.
后面如果接动词一定要用动名词.
She sings as well
as playing the piano.
5, nor是否定连接词, 后面接的句子应倒装.
I don't know, nor
do I care.
因为nor是连接两个句子, 如果连接的不是句子,而且前面有否定词的时候,不用nor而是用or. 除neither以外
Never try to talk or argue with Mary.
6, but除了可以连接句子表示转折以外,还可以用在no one,
none, nobody, nothing, all, every等词之后表示"除了…以外"
He tried hard but
he was unsuccessful.
All the boys but
one are here.
7,
however, nevertheless, still, yet,含意相同相当于"but…anyway".
adv. (conj)
The car was old,
yet(nevertheless) it was in excellent condition.
She has her
weaknesses, yet(but) that doesn't mean she is not qualified for the job.
He lied to me, yet
I still believe him.
8, while表示的是"相反的",也可以用but, however, on the other hand来代替.
While some people
have nothing to eat, others eat too much.
9, or连接句子或词组 "或者"
Which do you
prefer, yellow, blue or red?
Was he angry, or
was he pretending?
10, or,
or else, otherwise都是否则的意思.
Be quick,
or/otherwise you will be late.
11,
either … or/neither … nor的动词同样是临近原则.
Either Mary or her
parents are going by bus.
There is neither
electricity nor free suppers in the hotel.
12, so表示因此, 相当于therefore.（adv.）
They cost a lot of
money, so use them carefully.
It is very cold.
Therefore, we should stay here.
13, then
（adv）然后，而后，其次
I dropped in at her
house and then I went home.
14, for不可以放在句首;之前必须由逗号; 表示推论的理由

friends, for they are always together.
(二), 从属连词
1, that引导名词性从句(主语/宾语/表语从句),同位语从句，定语从句,…
That smoking can
cause cancer is known to all.
I was surprised to
hear that he became the president.
2,
whether/if(是否) if 能引导宾语语从句

whether it is true or not.
I haven't decided
whether/if I'll go with you.
在介词后,名词后,不定式前和有or not的句子中用whether.
I am worried about
whether she is happy.
3, when,
while, as
when 在---时刻或时期，可指时间点或时间段，从句动词是终止或持续动词。When I
got home, he was having supper.
When I was young, I
liked dancing.
As 表示"边---边---"或"与---同时"表示动作同时发生伴随进行。动词相似。如终止性动词为从句，则主句也为终止性动词。
They talked as they
walked.
While表示只是时间段，不是时间点，从句的动词只限于持续动词。
While I slept a
thief broke in.
When 可以表示主句和从句先后发生.
When he has
finished his work, he takes a short rest.
When 从句为终止动词不能为while 替换
When he came
yesterday, we were playing basketball.
如从句动词为终止性动词，主句也是终止性动词 when 和as 可以互换。
He came just as I
reached the door.
从句表示状态可以用while.
We should strike
while the iron is hot.
4, after/before
After her husband
died she had to take everything on herself.
Take the medicine
before you go to bed.
5, since引导的从句是肯定句,一般主句都是完成时,

若是"it was …
since"从句必须用过去完成时.

7, as
soon as

news as soon as I see him.
8, once(一旦)相当于as soon
as

of her that not long after she was restored to health.
