定語從句與其近似句型簡析
⒈ ⑴ It is such a modern machine few of the workers know how to operate it .
⑵ It is such a modern machine few of the workers know how to operate .
A. which B. that C. as D. the one
析：⑴ B ⑵ C 句 ⑴ 是 such … that 引導的結果狀語從句。句 ⑵ 是定語從句，先行詞前有 such 修飾時用 as 引導，as 在定語從句中作 operate 的賓語。
⒉ ⑴ Is this museum they visited last week ?
⑵ Is this the museum they visited last week ?
⑶ Is this farm you used to work ?
A. where B. that C. in which D. the one
析：⑴ D ⑵ B ⑶ A 句⑴、⑵是定語從句：句 ⑴ the one 是先行詞，后面省略了 that 。句 ⑵ 關系代詞 that 在定語從句中作 visited 的賓語，此句還可用 which 或省略關系代詞。句 ⑶ 是 where 引導的表語從句。
⒊ ⑴ is well known to us all , the earth goes around the sun .
⑵ is well known to us all that the earth goes around the sun .
A. That B. As C. It D. Which
析：⑴ B ⑵ C 。句 ⑴ 是由 as 的非限制性定語從句，代替后面整個句子。句 ⑵ 是it 引導的主語從句。 it 是形式主語，真正的主語是 that 引導的從句。
⒋ ⑴ I have two sisters , are doctors .
⑵ I have two sisters , and are doctors .
A. both of them B. both of whom
C. neither of them D. each of whom
析： ⑴ B ⑵ A 。句 ⑴ 是定語從句， 因從句中動詞是 are ，所以只能選 B ，而不能選 D 。句 ⑵ 因有并列連詞 and ，所以是并列句，再根據主謂一致原則，只能選 A 。
⒌ ⑴ I'll never forget the days I spent with him .
⑵ I'll never forget the day I was born .
A. when B. that C. on which D. both A and C
析：⑴ B ⑵ D 。 句 ⑴、⑵都是定語從句，句 ⑴ 中 that 在從句中作 spent 的賓語，還可用 which ，也可省略。句 ⑵ when 在定語從句作狀語，也等于 on which ，故選 D 。
⒍ ⑴ Was it October 1 , 1949 the People's Republic of China was founded ?
⑵ Was it on October 1, 1949 the People's Republic of China was founded ?
A. in which B. on that C. that D. when
析：⑴ D ⑵ C 句 ⑴ 是 when 引導的定語從句，句 ⑵ 是強調句，特別注意句 ⑵ 中 October 之前的 on 。
⒎ ⑴ He is the only one of the students who the accident .
⑵ He is one of the students who the accident .
A. knows B. know C. had known D. known
析：⑴ A ⑵ B 句⑴、⑵都是定語從句，在“ the ( only ) one of + 復數名詞 + 定語從句”結構中，先行詞是 one ，而不是復數名詞，故從句中謂語動詞用單數。但是在“ one of + 復數名詞 + 定語從句”句型中，先行詞是復數名詞，故從句中謂語動詞用復數。
⒏ ⑴ Do you know the fact the sun is brighter than the moon ?
⑵ Do you understand the easiest fact he explained to you just now ?
A. that B. which C. the one D. as
析：⑴ A ⑵ A 句⑴是 that 引導的同位語從句， that 在從句中不作任何成分，不能省略。句 ⑵ 是 that 引導的定語從句， that 在從句中作 explain 的賓語，因先行詞 fact 之前有最高級限制 easiest ，故只能用 that ，不可用 which 。
⒐ ⑴ This is the best reason he could give at the meeting .
⑵ This is the reason he didn't go to school this morning .
A. why B. that C. which D. because
析：⑴ B ⑵ A 。 句 ⑴ 是 that 引導的定語從句，that 在從句中作 give 的賓語，因先行詞 reason 之前有 best 修飾，故只能用 that 。句 ⑵ 是 why 引導的定語從句，相當于 for which 。
【指點迷津】
是定語從句還是狀語從句 ？
你在做這樣一道選擇題時，該選哪個答案呢？
While reading the book , we'd better make a mark we have any question .
A. at which B. at place where C. in which D. where
你或許要選擇選項 A 或 C ，因為你認為此句含有一個介詞 + which 引導的定語從句，然而句中的“ mark ”在邏輯意義上并非先行詞，因為我們決不是在 mark 上有任何問題，所以 A 和 C 都不是正確選項。那么選擇 B 正確嗎?回答是否定的，雖然選項 B 中的“place ”可以充當 where 引導的定語從句的先行詞，但單數可數名詞被限制性定語從句表特指的概念，“ place ”前應有 冠詞“ the ”。正確選項只能是D 了，即是由 where 引導的地點狀語從句，此句中的 where 等于 at the place where 。再看下列句子。
I'd like to take the pictures where stands the ancient tower . 我想在古塔那個地方照幾張像。
Please put the chair where it was when the meeting is over . 請在會后把椅子放回原處。
Young people should go where they are badly needed . 青年人應該到最需要他們的地方去 。
以上三個句子均含有 where 引導的地點狀語從句，句中的 where 可分別是由 in the place where , at the place where , to the place where 等替換。綜上所述，引導地點狀語從句的 where 通常可由適當的介詞 + the place + 關系副詞 where 替換，只要我們抓住這個關鍵就不難準確判斷和使用 where 引導的定語從句和地點狀語從句。最后再請試做下列選擇題。
⒈ Many old people like to live there are many trees and flowers .
A. in which B. the place where C. in the place where D. which
⒉ This kind of bamboo grows best it is wet and warm .
A. which B. in which C. where D. the place in which
⒊ Africa is actually connected with Asia at the spot the Suez Canal was dug .
A. which B. in the place where C. the place where D. where
⒋ This is the laboratory we made the experiment the other day .
A. in the place where B. that C. which D. where
⒌ The nurse asked the children to sit they were .
A. at place where B. where C. the place where D. which
答案：1-5 CCDDB
二、學海導航
【學法指要】
單元重點詞匯點撥
1 . develop 用作及物動詞，有四種意思。
〖點撥〗( 1 ) 發展……，使發育。例如：
He said it was right to develop heavy industry in this city . 他說在這個城市發展重工業是合適的。
Having sports will develop your health . 運動會增進健康。
Milk will be helpful in developing a child's body . 牛奶對孩子身體發育有幫助。
( 2 ) 發揮，開發，啟發。例如：
They are developing a new coal mine . 他們在開發新煤礦。
It's important to develop the mind of students in our teaching . 在我們的教學中啟發學生的思維是很重要的。
( 3 ) 產生，逐步顯示出。例如：
Don't let your children develop such a habit . 別讓你的孩子養成這樣的習慣。
He developed an interest in gardening . 他顯示出對園藝的興趣。
( 4 ) 沖洗。例如：
Films used to be developed in a chemist's in the past . 過去膠片常在藥房中沖洗。
2 . 用作不及物動詞，表示“發展”，“發育”，“發達”。例如：
The business is developing rapidly . 生意正在快速的發展中。
An interest in cookery developed in Mary when she was ten . 在瑪麗10歲的時候就有了對烹調的興趣。
Plants develop from seeds . 植物從種子長大。
A chicken develops in the egg . 雞雛在蛋中孵化。
另外，注意下列幾個句子的翻譯。
China is a developing country . 中國是發展中國家。
America is a developed country . 美國是發達國家。
There are many undeveloped countries in Africa . 在非洲有許多不發達國家。
2. 名詞 + 介詞 + 同一名詞
〖點撥〗year by year年年；每年，arm in arm 手挽手地，back to back 背靠背地，bit by bit 漸漸，day by day 逐日地，drop by drop 一滴滴地，end to end 頭尾相接，eye to eye 看法完全一致， ( an ) eye for ( an ) eye 以牙還牙，face to face 面對面地，hand in hand 手攜手地，heart to heart 推心置腹地 ( 坦白 ) ，little by little 慢慢地，man to man 真誠 ( 坦率地 ，one by one 依次，shoulder to shoulder 肩并肩地，step by step 逐步地，time after time 反復多次地 ( 再三 ) ，victory after victory 一個接一個的勝利，week after week 一周接一周地，word for word 逐字 ( 字對字地 ) ，year after year 一年接一年地
3. ink墨水；油墨（不可數名詞）
We are running out of ink .
〖點撥〗a bottle of ink一瓶墨水。in ink = in pen = with a pen 用墨水寫字。
4. method方法；辦法
This method is still being used in most schools all over the world .
〖點撥〗method指相當精心擬訂的一組方法，強調按步驟或系統進行實施的效率和精確性，常于介詞with連用，with these methods用這些方法。means作“方法”是單復數一樣，常與介詞by連用，by this / that means用這 / 那 種方法。way是常用的方法，不需要技巧性，常于介詞in連用，in this way用這種方法。
5. unknown不知道的
It is unknown to everyone . 那是人人都不知道的。
〖點撥〗sth / sb is unknown to sb某人或者某物是……所不知道的。注意該詞在下面句中的反意疑問句仍用否定形式：What he wanted was unknown to me , wasn’t it ?
6. sheet成幅的薄片；薄板；一張；被單
two sheets of glasses兩片玻璃。a sheet / piece of paper一張紙。
Please use a fresh sheet of paper for the next question .
Mother put the clean sheets on the beds for the guests .
7. include包括；包含
This plan includes most of your suggestions .
〖點撥〗注意including可以作介詞用，如：
The rent is 80 yuan a month , including water and electricity .
試對比其在獨立主格結構中的用法。
Everyone went to the exhibition , me included ( = me being included).
8. trip , journey , travel , tour
〖點撥〗trip 是旅行和訪問的總稱。在英國，trip 通常指短程的觀光旅行；在美國則包括搭乘短程交通工具以至徒步遠足的所有旅行。例如：
a bus trip 汽車旅行，a business trip 出差
Four people are planning a bicycle trip . 有四個人計劃一次自行車旅行。
How long will it take you to complete the trip ? 走完全程需要多長時間 ?
journey 常指長距離的、直接到達目的地的旅行。例如：
a day's journey 一天的行程，a journey by rail ( train ) 坐火車旅行
該名詞與動詞搭配時，可表達“旅行”這一動作。例如：
Why are you making this journey 你們為什么要作這次旅行 ?
可用 make a journey 也可以用 take a journey ; 還可以用 go ( start , set out ) on a journey . 等來表示“外出旅行”。
如果把人生也看作一次 journey，那么，He went on his last journey . ( 他踏上了人生的最后旅程。 ) ，實際是“死”的委婉說法。同樣 This is his journey's end . ( 這是他旅途的終點。 ) 與“他的死期已到。”意思完全一樣。
travel 也泛指旅行。如：
Which do you like better , sea travel or air travel ? 你比較喜歡海上旅行還是空中旅行 ?
I met a large number of people during my travel through America . 我到美國去旅行期間碰到了很多人。
travel 與 trip , journey 的最大區別在于：travel 是不可數名詞，不能與冠詞 a 連用。比較以下正誤：
［ 誤 ］I hope you had a good travel .
［ 正 ］I hope you had a good journey .
需要注意的是：盡管 travel 作“旅游、旅行”講時是不可數名詞，不與冠詞 a 連用，但是卻有復數形式 travels。這時，travel 可用來指包括訪問過好幾個地方的一次長時間的特別是海外的旅行。例如：
Did you go to Paris during your travels ? 你在旅途中有沒有去巴黎 ?
travels 還可以指“游記”、“游行筆記”，尤其指國外的“游歷”，用于此義時切不可用作單數。比較：
［ 誤 ］You should write a book on your travel .
［ 正 ］You should write a book on your travels .
tour 意為“周游”，常帶有根據一定的路線、事選預定了一些逗留地點，最后仍回到原出發點的含義。例如：
a tour round the world 環球旅行；a cycling tour 騎自行車旅游
它還可用來表示到許多地方觀光游覽，強調路線的曲折，也可用來指小區域的參觀。
We made a tour round a factory yesterday . 昨天我們游覽了一個工廠。
除此之外，voyage 指水上和空中的游歷、旅行，行程不分長短；outing 指短程的郊游、外出野餐，常用于口語中。

單元難點疑點思路明晰
1 . The Chinese have been making paper for two thousand years . 中國人造紙已經有兩千年的歷史了。
句中謂語 have been making 是現在完成進行時態，即由“have/has been + 現在分詞”構成。這種時態主要表示在以前這一段時間里一直在進行的動作，該動作可能仍在進行，也可能剛停止。該句用現在完成進行時表示“中國人在兩千年前已開始造紙，‘造紙’這一動作一直延續至今，而且將繼續進行下去。”這種時態和現在完成時的區別主要在于它強調動作在某一段時間一直在進行，該動作通常有現在的結果。例如：
Father has been working in this car factory for ten years . ( 指他現在仍在這家汽車廠工作，而且將繼續在這里工作。 )
Father has worked in this car factory for ten years . ( 指他至今為止在這家汽車廠工作了十年，至于今后是否還在這里繼續工作，要視具體情況來定。 )
2 . As there was no paper in these countries , no records were kept . 由于這些國家沒有紙，因此，也就沒有史料記載。
( 1 ) as 在此作連詞，意為“因為；既然”，引導原因狀語從句，常置于句首，主要表示明顯或以為明顯的原因。例如：
As it's sunny , I'll go for a walk .
As she didn't come , we left without her .
( 2 ) no 當形容詞作定語時，相當于 not a , not one 或 not any , 可修飾復數名詞，也可修飾單數名詞。no 修飾的名詞作主語時，謂語動詞的單復數形式視 no 后面的名詞的單復數形式而定。例如：
There's no telephone in our house .
There's no buses in this part of town .
3 . Although these were much more useful than the metal pots , they were still difficult to read and were very heavy to carry . 雖然這些比鐘鼎文有用得多，但是讀起來還很費勁，拿起來也很重。
( 1 ) much more useful than…中的 much 為副詞，修飾比較級，表示程度。類似的還有 a lot , a little , far , even , still 等。
It's much/far/a lot colder today than yesterday .
Now it's raining even/still harder than before .
( 2 ) difficult to read 和 heavy to carry 都屬于“形容詞 + 不定式”結構，不定式在形容詞后面作狀語。在此結構中，不定式用主動表式表示被動含義，它和句子的主語構成邏輯上的動賓搭配關系，能夠用于此結構的動詞主要有 easy , hard , difficult , light , cheap , important , interesting 以及它們的反義詞等。例如：
The old man is hard to get along with .
These novels are very interesting to read .
4 . This kind of paper was as soft and light as silk but much less expensive . 這種紙和絲帛一樣輕柔，不過便宜得多。
less 和多音節形容詞或副詞可以構成比較級，正如 more 一樣，但二者意思相反。此句中的 less expensive 即 cheaper。例如：
This story is less interesting than that one .
I think making model planes is less difficult than making model ships .
【妙文賞析】
Two Mistakes
For a long time Dr Smith had wanted to get a better job in a certain big modern hospital . He was appointed to a particular position which he wanted , and his wife moved to the house which they were now to live in . The next day some beautiful flowers were sent to them , with a note which said , “ Deepest sympathy (沉痛悼念). ” Naturally , Dr Smith was angrily to receive such an unusual mote , and telephoned the shop which had sent the flowers to find what the note meant .
When the owner of the shop heard what had happened , he apologize to Dr Smith for having made the mistake .
“ But what really worried me much more , ” he added , “ is that flowers which ought to have gone to you were sent to a person who had just died , with a card which said , ‘Congratulations on your new position . ’ ”
很久以來，史密斯醫生一直想在某一家大型的現代化醫院找一份比較錫樣的工作，這一天終于盼來了。他被任命為他想干的特殊位置，而他的妻子也搬進了他們現在住的房子。第二天送來一些鮮花，里面夾著一張條子，上面寫著： “ 沉痛悼念 ” 。
接到這樣一張奇特的字條，史密斯醫生自然很生氣，于是便給鮮花店打電話詢問怎么回事。
當店老板聽說發生的情況時，他忙向史密斯醫生道歉，說是送錯了。
“ 但真的使我更擔心的是， ” 他補充道， “ 本應該送到你那里的鮮花卻送給了一個剛死的人，鮮花里面夾著一張卡片，上面寫著：‘祝賀你搬遷新居。’ ”

單元語法發散思維
關系代詞 who 和 that 的用法區別
在定語從句中，若先行詞指人。其關系代詞可用 who，whom , 也可用 that。
The girl who ( that ) is speaking at the meeting is our monitor .
※ 在下列情況下多用或須用 who。
1 . 關系代詞在從句中作主語時，多用 who。
Do you know the man who spoke just now ?
The doctor who treated me was very experienced .
2 . 先行詞 all , anyone , one , ones 等時，多用 who。
All who heard the news were excited .
Anyone who breaks the rule will be punished .
3 . 先行詞為 those 和 people 時，多用 who。
Those who want can see sometimes act just as foolishly .
4 . 在非限制性定語從句中須用 who。
Tom's father , who is over sixty , still works hard .
Mr Green , whom you saw in the library yesterday , will teach us physics next term .
5 . 在被分隔的定語從句中須用 who。
A new teacher will come tomorrow who will teach you German .
6 . 在以 there be 開頭的句子中多用 who。
There is a stranger who wants to see our headmaster .
7 . 一個句子中帶有兩個定語從句，其中一個關系代詞是 that , 另一個須用 who。
The student who was praised at the meeting is the monitor that is very modest and studies very hard .
※ 使用 that 的幾種情況。
1 . 若先行詞前有形容詞最高級或序數詞修飾時。
He is the finest comrade that I have ever worked with .
The first person ( that ) I visited there was Mr Green .
2 . 先行詞前有 the same , the only 等修飾時。
She is the same teacher that was praised the other day .
She is the only person that understands me .
3 . 當主句是以 who 或 which 開頭的特殊疑問句時，定語從句須用 thet，以免與先行詞重復。
Who is the boy that was here just now ?
Which of us that knows something about physics does not know this ?
4 . 若先行詞兼指人與物時，須用 that。
We know nothing about the doctors and the hospitals that you are talking about .

He is not the man that he used to be .
He is not the naughty boy that he was five years ago .
【動腦動手】
單元能力立體檢測
A. 單元知識點精練
1 . - Has your teacher moved into the new building ?
- Not yet . The building ____ .
A . being built B . is building C . is being built D . is built
解析：本題四個選項中 A 不能用作謂語，排除。B 是現在進行時，而主語是物，不是正確答案 ( 主語是物時，應用被動語態 ) 。C、D 都是被動語態形式，但根據上、下文，用 C ( 現在進行時的被動語態 ) 比較恰當。
2 . The reason why he was late was ____ he had taken a wrong bus .
A . what B . whether C . now D . that
解析：這是一個含有兩個從句的復合句。why he was late 是定語從句，修飾 the reason；空白處以后應為表語從句。陳述句作表語時，應用 that 引導，故本題答案是 D。
3 . - I don't think I can walk any farther .
- ____ . Let's stop here for a rest .
A . Neither an I B . Neither can I C . I don't think so D . I think so
解析：根據語境，尤其是 Let's stop here for a rest 的暗示，空白處詞意應為我也不能。因為 C、D 明顯與題意不符。A、B 中都有 neither，但 A 中的動詞明顯與前句不一致，故答案應為 B。
4 . Has ____ been decided ____ the artist will attend the meeting ?
A . it ; that B . that ; that C . it ; it D . that ; /
解析：本題測試的是主語從句及 it 的用法。根據句意可知：句子后半部分是主語從句，由 that 引導，前邊用 it 作形式主語，故答案是 A。另外，也可把 It has been decided that…作為一個慣用句型記憶，表示“……已經被決定”。
5 . When I came into his room , Mr Black was reading ____ novel .
A . a new interesting historical B . an interesting historical new
C . a new historical interesting D . an interesting new historical
解析：本題測試幾個形容詞連用時的詞序排列問題。幾個形容詞連用，哪個在前，哪個在后，不是隨意排列的。一般情況下，緊挨名詞的形容詞應是說明名詞的用途或說明具體內容的；前面是表示形狀、狀態的形容詞；再前面是表示性質的形容詞。本題的答案為 D。多個形容詞連用時的順序是較復雜的問題，做題時應多讀幾遍，認真體會語感和平時的使用習慣。
6 . What is the difference ____ the pronunciation ____ these two words ?
A . with ; in B . in ; between C . at ; among D . about ; between
解析：本題重點測試 among 和 between 的區別和 difference 后的介詞搭配。句尾是“two words”，顯然 A、C 搭配不當，應予排除。difference 常用介詞 in 連用，表示“在……方面不同”，答案是B。再如：What's the difference in temperature between the day and the night ? ( 白天和夜晚的溫差是多少 ? )
7 . The harder you ____ , the better progress you ____ .
A . will work ; will make B . work ; have made
C . work ; will make D . will work ; make
解析：根據句意，前一句的意思是先決條件，后一句是結果。所以，work hard 和 make progress 的動作有先后之分，故前一空用現在時，后一空用將來時。答案是 C。

【創新園地】答案
We can make ourselves happy if we help others live happily . As everyone knows : “No human being can be really happy who is not giving or trying to give happiness to others . ” The way to make ourselves happy every day is to make the day a happy one to others . We can give someone a small thing in need , say a kind word to our unhappy neighbour , or offer a friend of ours unimportant help - these are enough to give happiness to others , and also to ourselves.
We should think first of others and last of ourselves . We should give up our own pleasure or our own way when necessary . It is much happier to give than to take . Selfishness is the greatest course of the human race .
