这是一份外研版 (2019)必修 第一册本册综合教案配套课件ppt，共19页。PPT课件主要包含了定语从句的概念，☆关系副词，关系代词比较等内容，欢迎下载使用。
Ask the students t find the differences f these sentences。The girl behind the tree is Kate.The man driving t fast was a drunk.The girl wh is behind the tree is Kate.The man wh was driving t fast was a drunk.
定语可以由形容词、代词、数词、名词、分词、不定式、介词短语等来担任，修饰名词。(以分词、介词短语为例） 例： The girl behind the tree is Kate. The man driving t fast was a drunk.
在英语中，修饰名词或代词的句子叫定语从句。 例： The girl wh is behind the tree is Kate. The man wh was driving t fast was a drunk.
2.定语从句的构成要素
①先行词（被修饰的名词或代词）②引导词：关系代词或关系副词注意:从句与先行词是修饰与被修饰的关系eg: This is the factry where he wrks.
The building is ur schl. The building stands by the river.= The building which/that stands by the river is ur schl. 先行词 关系词 从句 which、that 是关系代词，它在从句中代替先行词the building, 同时担任从句中的主语，也起连词的作用，把两个简单句连接 起来。
关系代词的使用取决于先行词，它们的关系非常密切，因为关系代词在定语从句中代替主句中的先行词，所以它在一般情况下都跟在先行词之后，而且它的 人称、数必须和先行词一致。
The wman that/wh is speaking at the meeting is my mther.(主句) The wman is my mther(从句) The wman is speaking at the meeting.
3.引导词——关系词的分类
4.定语从句的考查方向:引导词的考查
理解掌握几个区分:①区分that 和which②区分as和which ③区分定语从句和状语从句 ④区分定语从句和名词性从句 ⑤区分定语从句和强调句型
☆关系代词普通代词与关系代词的区别I have a sister.She wrks in Shanghai. 代替 sisterI have a sister wh/that wrks in Shanghai.普通代词：只起代替的作用（如上例she)关系代词： （如上例wh/which）
1. 除了代替先行词外，2.它还在定语从句中担任一定的成分，3. 同时连接先行词与它引导的定语从句。 （把主句和从句连起来）
Where（先行词是地点名词，且定语从句缺地点状语时用）When（先行词是时间名词，且在定语从句缺时间状语时用）Why （先行词是reasn，且在定语从句缺原因状语时用 ）
1．Please pass me the ntebk ______ cver is yellw．2．Li Hua was ne f the girls ____ have the chance t g abrad.3．He must be frm Africa, ————— can be seen frm his skin．4．Air, _____ we breathe every day, is arund us all the time．5．1949 was the year ____ the New China was brn．6．I dn't knw the reasn ____ she lks unhappy tday．7．This is the village _____ my father wrked three years ag．8．I still remember the day ____ the ld scientist tk us t the lab fr the first time．9．The letter ______ I received yesterday is frm my sister．10.

关系代词和关系副词的易错点
I dn’t knw the reasn yu were absent frm the meeting, but I’m sure that smene will tell me the reasn yu haven’t tld me.2. The htel we stayed wasn’t clean.3. The htel we visited last night wasn’t clean.4. The day , yu’ll spend in yur hmetwn, is day, yu’ll stay in yur hmetwn , is cming
why / fr which
关于介词＋关系代词which/whm
He built a telescpe he culd study the skies.The glasses, I’ll be blind, is lst.I’ll never frget the day I jined the army.D yu knw the man yu just shk hands?
thrugh which
withut which
③先行词被the nly, the very, the same, the last等词修饰。
1）下面情况只用that不用which和whm: I watched all the glasses were n the table fall ff the table. The parks are the clearest parks yu can imagine． Crn was nt the nly fd was taken t Eurpe． They talked abut things and persns they remembered. Wh is the persn yu just talked with? The village is n lnger the ne it was 5 years ag. There are many apples are very delicius.
①先行词为much, little, nne, smene, smething等不定代词。
②先行词有序数词或形容词最高级修饰。
④先行词既有人也有物。
⑤以wh /which开头的疑问句。
⑥先行词在主句中作表语关系词在从句中作表语时。
⑦在there be 句型中，指物只用that。
□that 和which 的区别
2）下面情况不用that: This is the bk abut we are talking nw． Tm studies hard and is ready t help thers, his parents expect.What’s that is flying in the sky?
③当先行词本身是that时：
that和which的区别
which和as的区别
1._______ is reprted in the newspapers , talks between the tw cuntries are making prgress. 2. Helen was much kinder t her yungest sn than t the thers , ______ , f curse , made the thers envy him .3. ________ is ften the case, we have wrked ut the prductin I explained n the phne, yur request will be cnsidered at the next married Mary, we expected.6. He married Mary, we didn’t expected.7. Let’s read such bks will make them better.8. He will give yu such infrmatin will help yu.
as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：①as引导的定语从句可置于句首，而which不可。②as代表前面的整个主句并在从句中作主语时，常可翻译为“正如，正像”；而which常译为“这一点，这件事”③ 在限制性定语从局中，如果先行词被as, s ,the same, such 修饰时，关系代词常用as
总结：which和as的区别
区分定语从句和名词性从句
1.The news that he wn the first prize fr the cmpetitin surprised all f us.
2.The news that he tld us surprised all f us.
