英語語法 定語從句1
定語從句在句中做定語,修飾一個名詞或代詞,被修飾的名詞詞組或代詞即先行詞。定語從句通常
出現在先行詞之后,由關系詞(關系代詞或關系副詞)引出。
關系代詞有:who, whom, whose, that, which等。
關系副詞有:when, where, why等。
18.1 關系代詞引導的定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞,并在句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主語時,從句謂語動詞的人稱和數要和先行詞保持一致。
1)who, whom, that
這些詞代替的先行詞是人的名詞或代詞,在從句中作主語和賓語。例如:
Is he the man who/that wants to see you? 他就是你想見的人嗎?(who/that在從句中作主語)
He is the man whom/ that I saw yesterday. 他就是我昨天見的那個人。(whom/that在從句中作賓語)
2) whose 用來指人或物,(只用作定語, 若指物,它還可以同of which互換)。例如:
They rushed over to help the man whose car had broken down. 那人車壞了,大家都跑過去幫忙。
Please pass me the book whose (of which) cover is green. 請遞給我那本綠皮的書。
3)which, that所代替的先行詞是事物的名詞或代詞,在從句中可作主語、賓語等。例如:
A prosperity which / that had never been seen before appears in the countryside.
農村出現了前所未有的繁榮。(which / that在句中作賓語)
The package (which / that)you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作賓語)
18.2 關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點或理由的名詞,在從句中作狀語。
1)關系副詞when, where, why的含義相當于介詞+ which結構,因此常常和介詞+ which結構交替使用。例如:
There are occasions when (on which) one must yield. 任何人都有不得不屈服的時候。
Beijing is the place where(in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer? 這就是他拒絕我們幫助他的理由嗎?
2)that代替關系副詞,可以用于表示時間、地點、方式、理由的名詞后取代when, where, why和介+which引導的定語從句,在口語中that常被省略。例如:
His father died the year (that / when / in which) he was born. 他父親在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago.
他不大可能找到他四十年前居住過的地方。
18.3 判斷關系代詞與關系副詞
方法一: 用關系代詞,還是關系副詞完全取決于從句中的謂語動詞。及物動詞后面無賓語,就必須要求用關系代詞;而不及物動詞則要求用關系副詞。例如:
This is the mountain village where I stayed last year. 這是我去年呆過的山村。
Ill never forget the days when I worked together with you.我永遠不會忘記與你共事的日子。
判斷改錯:
(錯) This is the mountain village where I visited last year.
(錯) I will never forget the days when I spent in the countryside.
(對) This is the mountain village (which) I visited last year.
(對) Ill never forget the days (which) I spent in the countryside.
習慣上總把表地點或時間的名詞與關系副詞 where, when聯系在一起。此兩題錯在關系詞的誤用上。
方法二: 準確判斷先行詞在定語從句中的成分(主、謂、賓、定、狀),也能正確選擇出關系代詞/關系副詞。
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案:例1 D,例2 A
例1變為肯定句: This museum is ___ you visited a few days ago.
例2變為肯定句: This is the museum ___ the exhibition was held.
在句1中,所缺部分為賓語,而where, that, on which都不能起到賓語的作用,只有the one既做了主句的表語,又可做從句的賓語,可以省略關系代詞,所以應選D。
而句2中, 主、謂、賓俱全,從句部分為句子的狀語表地點,既可用副詞where,又因 in the museum詞組,可用介詞in + which 引導地點狀語。而此題中,介詞on 用的不對,所以選A。
關系詞的選擇依據在從句中所做的成分,先行詞在從句中做主、定、賓語時,選擇關系代詞(who, whom, that, which, whose); 先行詞在從句中做狀語時,應選擇關系副詞 ( where 地點狀語,when 時間狀語,why 原因狀語) 。
18.4 限制性和非限制性定語從句
1) 定語從句有限制性和非限制性兩種。限制性定語從句是先行詞不可缺少的部分,去掉它主句意思往往不明確;非限制性定語從句是先行詞的附加說明,去掉了也不會影響主句的意思,它與主句之間通常用逗號分開。例如:
This is the house which we bought last month. 這是我們上個月買的那幢房子。(限制性)
The house, which we bought last month, is very nice.
這幢房子很漂亮,是我們上個月買的。(非限制性)
2) 當先行詞是專有名詞或物主代詞和指示代詞所修飾時,其后的定語從句通常是非限制性的。例如:
Charles Smith, who was my former teacher, retired last year.
查理史密斯去年退休了,他曾經是我的老師。
My house, which I bought last year, has got a lovely garden.
我去年買的的那幢房子帶著個漂亮的花園。
This novel, which I have read three times, is very touching. 這本小說很動人,我已經讀了三遍。
3) 非限制性定語從句還能將整個主句作為先行詞, 對其進行修飾, 這時從句謂語動詞要用第三人稱單數。例如:
He seems not to have grasped what I meant, which greatly upsets me.
他似乎沒抓住我的意思,這使我心煩。
Liquid water changes to vapor, which is called evaporation. 液態水變為蒸汽,這就叫做蒸發。
說明:關系代詞that和關系副詞why不能引導非限制性定語從句。
定語從句在句中做定語,修飾一個名詞或代詞,被修飾的名詞詞組或代詞即先行詞。定語從句通常
出現在先行詞之后,由關系詞(關系代詞或關系副詞)引出。
關系代詞有:who, whom, whose, that, which等。
關系副詞有:when, where, why等。
