英語語法順口溜：定語從句中的定從中的關系副詞
關系副詞when/where/why, 從中做狀莫懈怠;
時間用when原因why,地點where經(jīng)常在;
定語從句中的關系副詞有三個：when, where和why，它們在定語從句中分別作時間、地點和原因狀語。when指時間， where指地點，why表原因。例如：
I still remember the day when I first came to Beijing.
我仍然記得我初次到北京的那天。
The factory where his father works is in the west of the city.
他父親工作的那個工廠在城市的西郊。
That is the reason why I did the job.
那就是我為什么干這個活的原因。
關系副詞可替換，介詞加上關系代;
關系副詞可以由介詞加上which來替換。例如：
1)This is the house where (in which) I lived two years ago.
在這句中，where= in which
2) Do you remember the day when (on which) you joined our club?
在這句中，when= on which
3) This is the reason why (for which) he came late.
在這句中，reason= for which
關系代，關系代，that與who要除外;
挑選介詞要聰明，必看動詞和先行;
介詞后可用關系代詞，但只能用which或whom，不能用that 和who。那么，這個介詞怎么選呢?其一，可以看定語從句中的謂語動詞;其二，可以看先行詞。例如：
1) The pain from which the poor suffered in this area has attracted the attention of the public.
本句中用from 加 which, from與定語從句中的謂語動詞搭配，suffer from。
2) English is a useful tool in which I can communicate with foreign friends.
本句中用in加which, 和先行詞搭配，先行詞表語言，因此用in。
聰明反被聰明誤，只因亂用關系副;
關系副，關系副，定缺主賓它不住;
它不住，它不住，關系代詞來玩酷;
關系副詞在定語從句中是做狀語的，where做地點狀語，when做時間狀語，why做原因狀語，但要特別注意，如果定語從句中所缺的不是狀語，而是主語、賓語或表語，就不要用關系副詞，而要用關系代詞。例如：
1) I still remember the days _____ we spent together in the mountains last summer.
先看定語從句中所缺少的句子成分，spent是及物動詞，缺賓語，因此不能填when, 而要用關系代詞which或that。
2)This is the house ______ his grandfather once lived in.
先看定語從句中所缺少的句子成分，lived in, 明顯缺賓語，in是介詞，介詞后應該有賓語，所以不能填where, 而要用which或that。
3)Is that the reason _______ you explained to the teacher for your being late for school?
先看定語從句中所缺少的句子成分，explain后應該跟雙賓語，缺少一個賓語，因此不能用why, 而要用which或that。
【篇二】
英語語法順口溜：定語從句中的關系代詞
關系代詞到這里，主賓表定作用起;
關系代詞做賓語，省與不省全靠你;
到此為止，我們一共學了六個關系代詞，分別是：which, that, who, whom, whose, as ,這些關系代詞在定語從句中可以做主語、賓語、表語和定語，關系代詞which/ that/ whom做賓語時，可以省略。
【篇三】
英語語法順口溜：定語從句7---As/which/So /such …that
As/which在句末，若有否定as錯;
as和 which都可指代前面一句話，請看例句:
1)Alice received an invitation from her boss, which came as a surprise.
愛麗絲受到了她老板的邀請，這使她感到吃驚。
2)The weather turned out to be very good, which was more than we could expect.
天氣結果變好了，這是我們沒有預料到的。
若有否定as錯;
3)The result of the experiment was very good, _______ we hadn't expected.
A. when B. that C. which D. what
【簡析】答案是C。由于非限定性定語從句是否定結構，只能用which引導，不能用as來替代which。
句首只能用as,還有認知猜想詞;
置于句首時，非限定性定語從句只能用as引導。例如：
As is known to everybody, the moon travels round the earth once every month.
眾所周知，月亮每月繞地球一周。
與表示認知猜想的詞，如know, expect, see, report, 連用時，要用as。
1)As we know, smoking is harmful to one's health.
我們知道，吸煙對健康有害。
2)As is expected, his daughter entered a key university.
正如人們所期望的那樣，他的女兒考入了一所重點大學。
固定結構用as, the same /such/so/as;
1) 在the same …as….結構中。意思是 “像……一樣的”。 例如：
Chongqing is not the same city as we have seen in other places.
重慶和我們在其它地方看過的城市不一樣。
注意區(qū)分: the same ….that….,請看例句：
This is the same pen that I lost. 這正是我所丟的鋼筆。(同一)
This is the same pen as I lost. 這支鋼筆和我丟的那支一樣。(相似，不是一個)
2)在as...as結構中，意思是“像……那樣的”。例如：
No period in history has had as many important changes _______ have taken place in the past century. 沒有哪個歷史階段像過去的一個世紀這樣有如此多的重大變化。
3)在such…as…結構中, 意思是“像……那樣的”。例如：
Mathilde had to work hard day and night and bought such a diamond necklace as she had lost to pay back to Jeanne.
馬帝爾德不得不日日夜夜地干活，來買一個像被她丟掉的那樣的鉆石項鏈還給讓。
So /such …that賓不離，so/such…as賓要棄;
在so/such…that結構中，that后引導的不是定語從句，而是狀語從句，從句中必須有賓語;在so/such…as結構中， as后引導的是定語從句，從句中不帶賓語。
例如：
1)He studies in such a good school that all other students in his village admire him.
他在那樣好的一所學校學習，以至于村子里其他的學生都很羨慕他。
解析：that后是狀語從句，狀語從句中有賓語him。
2)He studies in such a good school as all other students in his village admire.
他在那樣好的一所學校學習，村里的其它學生都很羨慕那所學校。
解析：as后是定語從句,as代替先行詞school,在定語從句中做admire的賓語。
