Step 5 Sentence focus
1. This gift was the Amber Room，which was given this name because several tons of amber were used to make it.
這件禮物就是唬拍屋，它之所以有這個名字；是因為造這間房子用了好幾噸瓏拍．
這是一個復合句，句中which was given this name because several tons of amber were used to make it為非限制性定語從句，從句中又含有原因狀語從句because several tons of amber were used to make it。
非限制性定語從句，修飾物時用which, whose；修飾人時用who, whom, whose。非限制性定語從句和它的先行詞之間只是松散的關系，往往是對先行詞作補充說明，這種從句在朗讀時有停頓，在文字中通常有逗號與主句隔開。例如：
The chairman，who spoke first，sat on my right.
主席坐在我的右邊，他最先發言。
The speech，which bored everyone，went on and on.
那演講一直在進行，大家都覺得厭煩。
關系副詞where和when也能引導非限制性定語從句。例如：
On April 1 they flew to Beijing，where they stayed several days.
4月1日他們飛到北京，在那里待了幾天。
I'm seeing the manager tomorrow，when he will be back from New York.
我明天要去見經理，他明天從紐約回來。
另外，由which引導的非限制性定語從句，有時候修飾整個句子或句子中的某個部分。例如：
They have invited us to visit their country，which is very kind of them.
他們非常友好地邀請我們去訪問他們的國家。
They usually take a walk after supper，which does them a lot of good.
他們通常晚飯后去散步，這么做對他們很有好處。
2. The design of the room was in the fancy style popular in those days.
屋子的設計是當時流行的極富藝術表現力的建筑式樣。
這是一個“主系表”結構的句子,in the fancy style...在句子中用作表語，注意介詞in的用法，此處表示“以……方式，以……式樣，以……風格”。類似用法有in a different way等。
popular in those days是形容詞短語修飾the fancy style,形容詞詞組作定語時，通常都作后置定語。例如：
They have a house larger than yours. 他們的房子比你的大．
The boys easiest to teach are in my class. 我班上的男生最好教了。
嵌這類后置的定語在意義上相當于定語從句。例如：
a house larger than yours= a house which is larger than yours
the boys easiest to teach＝the boys who are easiest to teach
3. In 1770 the room was completed the way she wanted.
1770年，這間唬拍屋按照她的要求完成了。
句子中的the way she wanted作狀語，表示方式。此句實際為the room was
completed the way she wanted it to be completed, the way表示“方式；方法”，在定語從句中作狀語時，后面的從句的引導詞常常用that或in which或省略。例如：
I was never allowed to do things the way I wanted.
我從來就不被允許按照自己的想法去做事情。
We have to make it work in the way（that/in which) they want it to.
我們必須按照他們的想法把事情辦好。（此句中way在從句中作狀語）
He was looking at her in the way that surprised her.
他看著她的樣子讓她很驚訝。（注意此句中that可用which替換way在定語從句中作主語）
4. There is no doubt that the boxes were then put on a train for Konigsberg，which was at that time a German city on the Baltic Sea.
毫無疑間，這些箱子后來被裝上火車運往哥尼斯堡，當時它是波羅的海邊的一個德國城市。
這是一個復合句,that the boxes were then put on a train for Konigsberg是同位語從句，表示與之同位的doubt的實際內容。which was at that time a German city on the Baltic Sea是Konigsberg的非限制性定語從句，先行詞為Konigsbergo
同位語從句常用that來引導，但隨著與其同位的名詞不同，也可由when, where,whether, how等來引導。例如：
They had to face the fact that the nearest filling station is thirty kilometers away. 他們不得不面對這樣一個現實：最近的加油站還在30千米外。
The doctors came to the conclusion that the patient was suffering from cancer. 醫生們作出了診斷結果：病人身患癌癥。
I have no idea when he will return.我不知道他何時回來。
* There is no doubt that...可作為固定句型來用，意思是“毫無疑間……”。例如：
There is no doubt that he is a fine scholar.
毫無疑問他是一位優秀的學者。
There is no doubt that you can find a way to solve this problem.
毫無疑問你能找到解決這個問題的辦法．

3. Sum up：Restrictive ＆ non-restrictive clauses.
Do the following pair of sentences mean the same thing?
My uncle，who lives in London，is very rich.
My uncle who lives in London is very rich.
The first sentence has a non-restrictive clause within two commas，and the second has a restrictive clause. A non-restrictive clause simply adds more information into the sentence and does not affect the meaning of the main clause；it is therefore bracketed off with commas. Conversely，a restrictive clause defines its referent in the main clause more specifically and contributes significantly to the meaning of the sentence.
