which既可代指先行词,又可代指整个主句的内容。相当于 “and this” 或 “and that”. 译为“这一点”。as只能代指整个主句的内容。常带有“正如”之意,且已形成固定结构: as is known, as is reported, as is said, as is expected, as we know, etc.1. Einstein, as is known, is a famous scientist.

important country in the world.
3. Taiwan belongs to China, as is known to
all.

light.

is expected.3. 先行词前有the same, such限定时,关 系词只能用as.
I have the same opinion as you (have).
Don’t read such books as are beyond your ability.当先行词受the same 修饰时,有时也用 that引导定语从句,但与as引导的定语从句意思有区别。
She wore the same dress as her younger sister wore.?
She wore the same dress that she wore at Mary’s wedding.? 关系副词的用法where 引导的定语从句也可以修饰case, condition, situation, instance, 等先行词。
There are cases where this rule does not hold good.
Can you think of a situation where this word can be used?the reason why…is that… ……的原因是……他辞职的原因是他和老板吵架了。The reason why he resigned was that
he quarreled with his boss.Mencius believed that the reason why man is different from animals is that man is good. 在the reason why …结构中,why 引导定语从句,它也可以换为for which或者省略。在从句中作原因状语。
如果关系代词指代先行词reason在从句中作主语、宾语、表语等时,则用that或which。
3. the reason is that…结构中,只能用that
引导表语从句,不要受汉语的影响,误用because。关系代词和关系副词如何区别?1.The reason _______he missed the speech is that he forgot the time.

4.I’ll remember the day________we stayed together at that time.
5.This is the factory____________we visited last year.
6.This is the house _________Lincoln once lived.Remember: 引导词用关系代词还是用关系副词关键要看他们在从句中作什么成份而定。或者说,假如把先行词放到从句中是作主语、宾语还是状语而定。whythatwhichthatwhichwhenthatwhichwhere7.(1) He still lives in the room ________window faces to the south.

(1)There are lots of good English programmes which are
broadcast on TV or the radio in China.
------There are lots of good English programmes ________
on TV or the radio in China.
(2)At one time there were long queues of people who were
waiting outside the CAAC offices.
------At one time there were long queues of people ________
outside the CAAC offices.分析基本规律:从句是主动形式,用现在分词; 从句是被动形式,用过去分词。或者看定语和被修饰词之间的关系,如果定语和被修饰 词之间是主谓关系,用现在分词;如果定语和被修饰 词之间是动宾关系,用过去分词;
broadcastwaiting2.定语从句和并列句
1. I saw some trees, and the leaves of the trees were black with disease.
-----I saw some trees, the leaves of ________were black with disease.
2. The professor is an ordinary-looking little man, on the nose of __________there is a pair of glasses

(1)This is such a big stone _______no one can lift it.
This is such a big stone _______no one can lift.
(2)Please put the letter in the drawer _____ ______he
can easily find it.(=where)
Please put the letter_________he can easily find it.
(3) Please put the letter in which he can easily find it.
这句子正确吗?分析:(1)句从引导词来看,状语从句中的that 是连词,在从句中不充当任何成分,而定语从句中的as在从句中要作一个成分(主语,宾语或表语)。thatasin whichwhere4.定语从句和名词性从句
(1) He did all (that) he could to help me .(=what)
(2) All that can be done has been done. (=what)

AsthatWhat7.定语从句和强调句
(1) It is in this room ______I lived last year.
It is the room _______I lived last year.
(2) It was at seven o’clock ________he went
to school this morning.
It was seven o’clock _______he went to
school this morning. 分析:强调句句型:It is/was +被强调的成份+that/who +其它部分去掉 It is/was….that/who… ,句子照样成立。(1) I lived in this room last year. (2) He went to school at seven this morning.而定语从句的引导词在句中要作一成份。thatwherethatwhen8.定语从句和同位语从句
(1)The news ________our volleyball team won the
match made us excited.
(2)The news __________he told me yesterday is exciting.
(3)The problem __________we should answer for the
accident is clear to you.
(4)The problem __________he asked me to solve is hard to solve.分析:that 引导 同位语从句,在从句中不充当任成份,并且引导的句子是说明前一名词的内容, 在从句中不可省去,也不可用which 替代。That/which 引导定语从句,在从句中充当成份,作宾语时可省去,从句起说明主句性质和特征的作用。thatthat/whichthatthat/which高考命题导向:
