如何分析同位語從句?

同位語從句指的是從句在復合句中作同位語,它是同位語的壹種表現形式。這種作同位語的從句看起來似乎並不復雜,但在閱讀和翻譯中,如果我們缺少對它的分析,就有可能造成誤解。現將這種從句分析如下: ?A.同位語從句的實質 ?從句作同位語表示與之同位的名詞(短語)的實際內容,它的作用相當於名詞,對前面的名詞(短語)加以補充說明或進壹步解釋,相當於壹個表語從句,它們之間的關系是同位關系,即主表關系。如果用變通的辦法,把名詞(短語)和"主語+be+表語"結構聯系起來,就可以看出這種同位關系。試比較:

We all know the theory that matter is made up of atoms and molecules.?(=We all?know the theory, and the theory is that matter is made up of atoms and molecules.)?我們大家都知道物質是由原子和分子構成的這壹理論。 ?The suggestion that we should develop the natural resources in the region has been discussed.(=The suggestion is that we should develop the natural resources in the region, and the suggestion has been discussed.)關於我們應該開發本地區資源的建議已經討論過了。

The problem whether natural rubber is a polymer with linear chain molecules has been solved.(=The problem is whether natural rubber is a polymer with linear chain molecules, and the problem has been solved.)天然橡膠是否是線型鏈狀分子的聚合物,這個問題已經解決了。

I have no idea when she will be back.(=I have to idea, and the idea is when she

will be back.)我不知道她什麽時候會回來。 ?B.引導同位語從句的連接詞

引導同位語從句的連接詞最常見的是that。that是壹個純引導詞(pure introductory word),在同位語從句中常可省去,尤其是在口頭語中。例如:

I had the impression (that)your government was undecided about assisting us. 我的印象是,妳們政府還沒有決定援助我們。

"Billing and cooing! That's the way (that) you think of it! That's the way (that) you talk of it!

As though it were something you had to do.""談情說愛!這是妳的想法!這是妳的說法!仿佛這是妳的義務似的"。

連接詞when, where, why, whether, how 等也可引導同位語從句,這些連接詞除有連接主句和同位語的語法功能外,還有壹定的"疑問"意義。例如:

He has solved the question why he is ill. 他已經解決了他為什麽生病的問題。

Have you any idea how fast sound travels? 妳知道聲音傳播有多快嗎?

連詞but that 也可引導同位語從句,人它通常出現在"否定詞+doubt (deny, question)等名詞"結構之後。這時,but 無否定含義,僅起強調作用,常可省去;有時也可省去that而保留but。例如:

There is no question (but) that the four modernizations will be realized in China by?the end of the century. 中國在本世紀內實現四個現代化,這是沒有問題的。

There is no doubt but (that) we will succeed in designing the project.毫無疑問,我們能把這項工程設計出來。 ? C.同位語從句的先行詞

同位語從句的先行詞通常是抽象名詞,常見的有:idea, situation thought, fact, evidence,?belief, doubt, fear, hope, question, theory, news, order, ability等等。例如:

Wives lived in fear that their husbands might be killed. 妻子們擔心丈夫會戰死, ?提心吊膽地過日子。

How did the cheats explain the fact that the Emperor didn't feel the new clothes in him? 皇帝覺得身上並沒有穿上新衣,對這個問題騙子是怎樣解釋的 Is there any reason that he chose that honest old prime minister to go and find out? 他挑選那位誠實的老宰相去了解真相,有什麽緣故嗎 代詞it可用作同位語從句的先行詞。這個it常放在某些動詞或短語動詞後作賓語,同時兼作其後that同位語從句的先行詞。例如: ?We take it that you will act according to the final agreement. 我們認為妳方是會按照最後協議行事的。 ?In measuring electromotive force with a voltmeter, we should see to it that the

voltmeter is placed in parallel with the electric source. 用伏特計測量電動勢時,

務必使伏特計與電源並聯。 ?I owe it to you that I am still alive. 幸虧妳,我現在還活著。

有的語法學家把先行詞it後的that從句看作是動詞或介詞的真正賓語。我們認為,這種it後的that 從句應看作it的同位語,因為它相當於"主語+be+表語"結構。試比較:

You must se to it that the children don't catch cold.(=You must see to it, and i

t is that the children don't catch cold.)妳要當心,別讓孩子們著涼了。

D."復合介詞+the fact+that從句"結構從總體來看,這種結構屬介詞短語。如果分開來理解,其中的the fact 用作復合介詞的賓語,同時兼作其後that從句的先行詞,that從句為同位語從句。例如: ?It is chiefly due to the fact that the sun gets higher in the sky in summer and

shines more directly down on that part of the earth.

這主要是由於夏天太陽在空中的位置較高,同時更加直接地照射著地球的那壹部分。 ?We must never overlook our small weak points because of the fact that we have ma

de big achievements. 我們不可因為有了大的成績就忽視小的缺點。

Owing to the fact that I had lost his address, I didn't know where I could find

him.由於我把他的地址遺失了,所以我不知到哪裏去找他。

這種結構中的復合介詞很多,常見的有:due to, by dint of, by virtue of, because of, on? account of, in view of,等等。 ?E.同位語從句與先行詞之間的分隔同位語從句壹般都緊跟在與其同位的名詞(即先行詞)之後,但當先行詞作句子的主語,其謂語較短,同位語較長時,同位語從句常與同位名詞(短語)分隔。例如:

In the first half of the last century the discovery was made that a magnet could ?be used to get an electric current. 上個世紀的前半期,發現可用磁鐵產生電流。

The boy bore up well when the news came that his father had been killed. 當消息

傳來,說他父親犧牲時,這孩子表現得很堅強。

The theory is of great importance that the hotter a body is, the more energy it

radiates. 物體的溫度愈高,放射的能量愈多,這壹理論非常重要。

當前壹同位成分的名詞中心詞(即先行詞)有後置修飾語(如短語或定語從句等)時,同位語從

句常可能遠離其先行詞。例如:

For example, we know that the statement commonly accepted when the first edition

of this book was printed, that life was altogether absent in the deeper parts of the sea, is not true. 例如,在海洋深處完全沒有生命這壹說法,在本書第壹版付印時

是人們所公認的,但現在我們知道這並不正確。

An indistinct idea he had, that the child was desolate and in want of help.他心

裏有壹種模糊的概念,就是這孩子是無人照顧的,需要幫助
