內(nèi)容

一、教法建議

【拋磚引玉】

單元雙基學(xué)習(xí)目標

Ⅰ. 四會單詞和詞組：have a seat , quarrel , long before , dare , upon , fasten , gun , again and again , blow (n .) , hall

   三會單詞和詞組：personal , affair , relative , delay , pillow , nail , chest , pay … a visit , furniture , armchair , pet , doubt , silence , in silence , living room , strike , scream , snake , tiny , nephew , niece , connect to

Ⅱ. 交際英語：

1. I’m afraid I have to go now .

2. It is time sb + 動詞的過去式

3. I hope you have a good journey back to …

4. It was nice to meet you .

5. Please remember me to sb請代我向……問好

6. I called to tell you that …

7. I’d like you to meet …

8. Thanks again for calling .

9. It is very kind of you to do …

10. I have to see to . 我必須處理 。

Ⅲ. 語法重點：

本單元復(fù)習(xí)過去分詞作定語和狀語的用法。過去分詞可以作名詞的前置定語，也可以作名詞的后置定語。當過去分詞作狀語時，要注意其邏輯主語的問題。

另外要學(xué)習(xí)同源賓語的用法，如：( page 2 Unit 13 )

    Einstein ( lived ) the rest of his ( life ) quietly in the USA . ( 愛因斯坦在美國靜靜地度過了余生 ) 。其中賓語 life 與 live 是同源的名詞，即同源賓語 ( cognate object ) 。這是中學(xué)英語課本中十分常見的語法現(xiàn)象，這種賓語用在某些不及物動詞之后，并往往有定語修飾，現(xiàn)舉例如下：

    1 . My grandmother lives a happy life in the countryside . 我的祖母在鄉(xiāng)下過著幸福的生活。

    2 . Premier Zhou Enlai fought a hard fight against “Gang of Four” .     周恩來總理與“四人幫”進行了一場艱苦的斗爭。

    3 . He breathed his last breath last night .  昨天夜里他咽了最后一口氣。

    4 . He laughed a hearty laugh at the good news . 聽到好消息后他開心地笑了。

    5 . Chris will sing us a pop song . 克莉斯將給我們唱首流行歌曲。

    6 . Her son died a hero's death in the war . 她兒子在戰(zhàn)爭中英勇犧牲了。

    7 . She sleeps a sweet sleep only on Sundays . 只有在周日她才能甜美地睡一覺。

    8 . I dreamed a pleasant dream last night . 昨天夜里我做了個愉快的夢。

    9 . My father signed a deep sign . 我父親深深地嘆了一口氣。

    10 . My mother smiled a happy smile when I passed the entrance examination .當我通過了入學(xué)考試時，我媽媽幸福地笑了。

【指點迷津】

單元重點詞匯點撥

1. delay推遲；耽擱

What delayed you so long yesterday ?

The train was delayed one hour by the accident .

〖點撥〗without delay毫無耽擱地，立即。after a delay of two hours延遲兩個小時以后。

注意：delay + -ing推遲干……。如：I’ll delay answering his letter until I feel like writing .

另外，put off + ing推遲干……。如：They put off holding the sports meet .

2. quarrel爭吵；吵架

He had a quarrel with his wife about  / over the housework .

〖點撥〗quarrel with sb about / over sth因為……向某人爭吵

3. dare與need

dare 和 need 這兩個詞的用法有它們獨特的地方。詞性有兩種而且不同的詞性決定了它們不同的用法。對中學(xué)生來講掌握它們的用法有一定的難度，無論教師從理論上如何解釋，但同學(xué)們在具體運用中都會出現(xiàn)浮光掠影，若明若暗，零亂殘缺，張冠李戴的現(xiàn)象。這兩個詞難就難在對詞性的判斷，它們可以作為情態(tài)動詞用(其后不帶 to)，又可以作為行為動詞用(后面要帶 to)。為了便于區(qū)分其詞性和掌握用法，同學(xué)們可以采用下面的口訣幫助記憶。

〖點撥〗口訣：“dare , need 真奇怪，既行為(指行為動詞)又情態(tài)(指情態(tài)動詞)，是行為，把 to 帶(指其后用不定式)，是情態(tài)，把 to “賣”(指其后去掉 to，只用動詞原形)。若 need (= want ，require) 的主語是某物，愿與 -ing (= to be done)結(jié)姻緣�！�

請做以下練習(xí)：

1） Something is wrong with my watch . It needs ____ .

    A . to repair    B . repairing    C . repaired    D . being repaired

2） I ____ to ask the teachers for advice in the office .

    A . dare not    B . not dare    C . dare don't    D . don't dare

3） He ____ come to school to give us a lecture on how to learn English .

    A . need    B . need to    C . needs    D . to need

4） She ____ do so .

    A . won't dare    B . dare not    C . will dare to   D . not dare

5） We ____ to think it over before we take action  .

    A . needing    B . needs    C . need    D . needed

［答案與簡析］1 ― 5 BDABC 。第一題選B；某物作 need 的主語，后面應(yīng)用動名詞的主動形式表被動含義。第二題選D；dare 用作行為動詞，其否定形式應(yīng)為“助動詞+ not dare to do sth . ”第三題選A；need 用作情態(tài)動詞，其后跟動詞原形。第四題選B；dare 用作情態(tài)動詞，直接加 not 表示否定。第五題選C；need 用作行為動詞，主語是人稱代詞，其后應(yīng)該是 need to do sth .

4. furniture (總稱) 家具

A lot of furniture will be bought for you .

〖點撥〗furniture是不可數(shù)名詞，表示件數(shù)要用量詞piece / set 。如：three pieces of furniture三件家具。

5. doubt懷疑；疑慮

I have no doubt that he will pass this examination .

〖點撥〗beyond doubt = out of doubt毫無疑問。

用于肯定句時用doubt if / whether …。用于否定句時用doubt that 。

單元詞組思維運用

1. have a seat = take a seat坐下

Entering the hall , he had a seat in the corner .

Have a seat and make yourself at home .

注意：have a seat用于直接引語。

2. long before = long time ago很久以前

She said that she had known your name long before .

注意：It wasn’t long before是一個常用句型，意為“不久”。before long不久以后

3. pay … a visit = pay a visit to對……進行參觀；對……進行訪問

That basketball team will pay Europe a visit before long .

注意：表示狀態(tài)的“在……參觀；在……訪問”用on a visit to 。如：These singers have been on a visit to Africa for a month .

4. in silence靜靜地 = silently

She alone sat under the tree in silence , looking straight forward .

5. again and again = over and over反復(fù)地；再三地

The student made the spelling mistakes again and again .

6. connect to連接；相連

    Please connect the two speakers to the amplifier .

注意：connect with與……相連接；與……有聯(lián)系。如：She is connected with the Smiths .

7. see to處理；負責

I have some personal affairs that I have to see to .

Will you see to turning off the lights ?

8. have a good / pleasant journey一路順風；一路平安

I hope you have a good journey back to Guangzhou .

9. fasten … to… 把……栓在……；把……系在……

He fastened a rope to a post .

10. do repairs維修；修理

A few building repairs were done a week ago .

We must do a lot of repairs on the house before we move in .

11. no matter不要緊；沒關(guān)系

注意：在It doesn’t matter 中，matter是動詞。

12. from that moment on從那一刻起

13. a long wait等很久

There will be a long wait before the next train comes .

Word came at last after a long wait .

14. in the dark在黑暗中

15. be supposed to do應(yīng)該干……

We are supposed to gather at the school gate at 7:30 .

16. a length of一段

18. fire back開火還擊

No one was allowed to fire back unless the order was given .

二、學(xué)海導(dǎo)航

【學(xué)法指要】

單元難點疑點思路明晰

1. I've got some personal affairs that I have to see to . 我有些私事非處理不可。

〖明晰〗1) affair, business 作“事物”講時，這兩個詞的意義很相近，常可通用。

Mind your own affairs (business) . 少管閑事。

business不能用復(fù)數(shù)，而affair特別是指重大或頭緒較多的事務(wù)時，常需要復(fù)數(shù)，在下面的句子里，這兩個詞不能通用。

Each Ministry of Foreign Affairs lodged a protest with the other .  雙方外交部向?qū)Ψ酵饨徊刻岢隹棺h。

Business before pleasure . 先辦正事，再談娛樂。

2)see to有“注意，照料，保證，修理，診治”等意思。例如：

Your shoes need seeing to . 你的鞋得修補了。

You ought to have your eyes seen to by a doctor . 你應(yīng)該請醫(yī)生治眼睛。

2. I dare say my uncle will . I have no other relatives . 我認為我叔父會得到這筆錢，我沒有其他的親戚。

〖明晰〗1)I dare say 的意思并不是“I dare to say”，而是和“也許”幾乎同義或者等于“我想”。

I dare say you're right . 我看大概是對的。

I dare say it will come later . 我想它以后會來的。

2)dare用作情態(tài)動詞時，后接動詞原形，主要用于疑問句和否定句或者表示不肯定意義的各種從句中。例如：

Dare you ask him ? 你敢問他嗎？

I dare not go there . 我不敢去那兒。

That is as much as I dare spend . 我只敢花那么多的錢。

3)dare作主動詞時是規(guī)則動詞，用法如下：

a)表示“敢”，后接動詞不定式，也可省去to。例如：

I don't know how he dares to appear in public .

I've never dared go back to look . 我從來不敢回去看一下。

3. I think it will be necessary for me to pay you a visit and  see  where you live . 我想有必要去拜訪你，看看你住在什么地方。

〖明晰〗1)句中的it用作形式主語。例如：

Is it necessary for us to meet/necessary that we meet ?我們有見面嗎？

2)pay a visit (to someone or something)/pay (someone or something) a visit表示“（短時間）訪問（某人，某物）”；“參觀（某物）”。例如：

Shall we pay your brother a visit this afternoon ?

4. Do you see that hole high up in the wall, about 18 cm by 9 ? 你看到墻壁上方那個大約18厘米寬，9厘米高的洞沒有？

〖明晰〗1)句中的high用作副詞，指的是高矮；而highly表示很高的程度（意思往往是 very much）。

The plane flew high above . 飛機高高地在上空飛。

An eagle circled high overhead . 一只鷹在頭上高高盤旋。

The goods on display are all very highly priced . 這些展銷貨物標價都很高。

He speaks very highly of the boy's behaviour . 他十分贊賞孩子的行為。

2)about 18 cm by 9用作后置定語，修飾that hole，介詞by表示面積、 體積的長、寬、高。例如：

The room measures fifteen feet by twenty feet . 房間寬十五英尺，長二十英盡。

5. Dr Watson and I will spend the night locked in your room . 我和華生就鎖在你的房間里過夜。

〖明晰〗1)第一人稱單數(shù)I與其他人連稱用時，通常的詞序是，第二、三人稱代詞在前， 第一人稱代詞在后。例如：

You and I can do it . 我和你都能做這件事。

You, Tom and I are to leave tonight . 我、你和湯姆今晚得離開。

2)句中的過去分詞locked用作方式狀語。例如：

Just then the old man entered (supported) by his son . 就在這時， 老人由兒子扶著走了進來。

He turned away (disappointed) . 他失望地走開了。

She went home (exhausted) . 她回到家時已精疲力盡了。

6. Immediately Holmes jumped up from the bed and struck a match . 福爾摩斯立即從床上跳起，劃燃一根火柴。

〖明晰〗The young lady rushed into the room immediately she heard the noise . 那位年輕的女士一聽到響聲就沖入房間。

第一例句中的 immediately 用作副詞， 表示“立刻， 立即”； 第二例句中的immediately用作副詞，表示“一……就……”，類似的說法還有instantly, directly, the moment, the minute, the instant等。例如：

I'll go there directly (=as soon as) I have finished my breakfast .

The moment I saw you I knew you were angry with me .

【妙文賞析】

    A teacher asked his students some challenging ( 難以回答的，具挑戰(zhàn)性的 ) questions to find the most intelligent ( 聰明的 ) students . His first question was:

     “ What can you get with one penny that can be used by the whole class for about an hour ?  ”

    After a while an answer came from a clever girl .

     “ I can get a candle . The whole class can be lit up ( 照亮 ) with its light .  ”

    The teacher praised the student for her smart answer before asking the second question .

    An answer came from monitor of the class .

     “ If we put a calendar ( 掛歷 ) on the wall , we can use it for a whole year .  ”

    After warm applause of admiration ( 羨慕的掌聲 )  , the teacher presented his third question:

     “ What can you get without paying anything that can be used for your whole life ?  ”

    This time there was no immediate response ( 答復(fù) )  .

     “ You get your name free of charge and you use it all your life .  ” Again the clever girl won applause from the whole class .

    Now came the teacher's last question:

     “ What can you get which can be used after your death ?  ”

    Immediately he saw his favorite student open her mouth .

     “ A coffin ( 棺材 )  , Sir .  ”

【思維體操】

根據(jù)短文內(nèi)容，在每個空白處填寫一個適當?shù)脑~（首字母已給出）：

    It was a cold evening . Old Hill was in the ward（牢房）a____(1) .   He was put there for stealing some v____(2) jewellery in a shop .  He  knew  he would be in p____(3) for more than five years . C____(4) was coming and  the other prisoners（囚犯）were set free . He couldn't talk with n____(5) .  The policemen who guarded（看守）him were b____( 6)   buying  the  presents  for their families and friends . He lay down on bed,   and  he  could  not  fall a____(7) though he often felt t____(8) when he tried to earn some money  for his family .

    Suddenly the old man h____(9) some noise . He sat up at once.  The  door o____(10) and in came two policeman. They put a young man  into  the  ward, l____(11) the door and left. Old Hill looked at the young man up and  down, who w____(12) the nicest clothes. “He must be from a r____(13)   family, ”O(jiān)ld Hill said to himself. “But for what has he been b____(14) here too ?”

    “What happened to you, young man ?”he asked .

    “I was out of l____(15) this morning,”said the young man.“I had a  puncture（扎穿）.”

    “It's an o____(16) accident, I think. Did you drive over a n____(17)?”

    “No, a wine bottle.”

    “You were too c____(18) ! But you haven't broken any l____(19) , in  my opinion.”

    “But the drunkard（醉漢）who was l____(20) in the street had it hidden  in his coat !”

答案與分析：

    Old Hill由于偷盜貴重的珠寶被關(guān)進了監(jiān)獄。圣誕節(jié)快到了，牢房里只剩他一個人，他感到很寂寞。突然兩個警察把一個年輕人關(guān)進了牢房。他打量那個衣著講究的年輕人，可以判斷他出身一個富有家庭。他問年輕人是為何被關(guān)進監(jiān)獄。年輕人說他的汽車輪胎被酒瓶扎破了。Old Hill認為那也不犯法。最后年輕人拐彎抹角地說，那個酒瓶是在一個躺在街道上的醉漢的大衣里的（意思是他從醉漢身上碾了過去）。

    1. 從后面所講的別的囚犯都釋放來看，Old Hill一個人在牢房里，要填alone。2. 從上下文可以得知，Old Hill由于偷盜貴重的珠寶才被關(guān)進監(jiān)獄的。因此，應(yīng)填valuable。3. Old Hill偷盜了貴重的珠寶，就得在監(jiān)獄里呆五年多。應(yīng)當填prison。4. 從監(jiān)獄的看守買禮物來看，是圣誕節(jié)到了。故應(yīng)填Christmas。5. 另外幾個囚犯被釋放了，牢房里只剩Old Hill一個人，他也就無法和任何人說話了。應(yīng)填nobody。6. 那些警察在圣誕節(jié)以前，忙于給親友買禮物。應(yīng)當填busy。7. Old Hill感到寂寞，躺在床上也睡不著，要填asleep。8. Old Hill在掙錢養(yǎng)家的時候，自然很勞累。所以，應(yīng)當填tired。9. 牢房有別的人，因此只要有動靜，Old Hill就會聽到的。應(yīng)填heard。10. 門開了人才會進來。故應(yīng)填opened。11. 警察在關(guān)進囚犯之后，先鎖了門才能離開。要填locked。12. 那個年輕人自然是穿著好衣服。應(yīng)填wore。13. 年輕人穿著講究，當然是出身有錢人家庭。要直rich。14. Old Hill不知道那個年輕人為何也被帶到監(jiān)獄來。故應(yīng)填brought。15. 年輕人認為他不走運，才出了那件事。應(yīng)當填luck。16. 汽車輪胎扎破并不是大事故，而是一件很普通的事情。因此，應(yīng)當填寫ordinary。 17. 一般情況下，汽車輪胎扎上釘子，才會被扎破的。要填nail。18. 年輕人說他從一個酒瓶上駛過去，才把輪胎扎破了。Old Hill 就說他太粗心了。要填careless。19. Old Hill認為，年輕人從灑瓶上駛過去也不犯法，故應(yīng)填law。20. 從年輕人的回答可以看出，那個醉漢是躺在街道上的。實際上， 他的汽車從醉漢身上駛過去了。這也是他被帶到牢房的原因。要填lying。

三、智能顯示   

【心中有數(shù)】

單元語法發(fā)散思維

過去分詞作定語、狀語

〖思維〗一、過去分詞作定語

1.過去分詞作定語時，單個分詞一般放在名詞之前，分詞短語必須放在名詞之后，這種情況與現(xiàn)在分詞作定語時相同。例如：

Her job was to take care of the (wounded) soldier .

We are doing our (written) exercises .

The machine (run by the old worker) is made in Shanghai .

2.過去分詞作定語時，多表示已完成的動作，但有時其所表示的動作卻尚未完成或有待于將來完成。例如：

The houses (built in the 19th century) has been on fire for half and hour. （動作完成）

the workers demand (increased) wage . （尚未完成）

3. 及物動詞的過去分詞還可用來表示被動， 但也有少數(shù)動詞（如fall, escape, boil等）的過去分詞作定語時，只表示完成。例如：

the man spoken to（別人與之講話的那個人）

boiled water（開過的水，表完成）

〖思維〗二、過去分詞作狀語

1.過去分詞可用來作時間、原因、條件、讓步、方式或伴隨情況的狀語。

1)表時間。例如：

(Heated), the metal expands .這種金屬加熱后會膨脹。

(Asked) why he did it, he said it was his duty .

2)表原因。例如：

(Born in the village), he knows a lot of people there .

3)表條件。例如：

(United), we stand; (divided), we fail .團結(jié)則存，分裂則亡。

(Given more time), I can do it better .

4)表讓步。

Although (exhausted) after a long journey, he continued to work .

5)表方式或伴隨情況。例如：

The professor stood there (surrounded) by many students .

〖思維〗三、尤其需要注意的是：過去分詞無論作什么狀語，其邏輯主語應(yīng)是主句的主語。

1.【誤】Seen from the mountain, we found the building is very small .

【正】Seen from the mountain, the building is very small .

2.【誤】Written carelessly, he made a serious mistake in the letter .

 【正】Written carelessly, the letter had a serious mistake .

【動腦動手】

單元能力立體檢測

一、過去分詞精練

1. The programs ____ (put) on yesterday evening were really wonderful.

2. ____ (send) to the hospital immediately, the wounded soldier was saved.

3. You'd better not get the plastic bags and boxes ____ (burn),  for  it  will give off some harmful gas and pollutants into the air.

12. Unless ____ (invite), I won't go to the ball tomorrow.

13. ____ (destroy) in the earthquake, the equipment doesn't work.

14. ____ (absorb) in the research work, he had no time to make any trip.

15. In the paper is a carefully ____ (decide) policy.

16. The first film ____ (direct) by her was very popular with the public.

17. The students have cleared away the ____ (fall) leaves.

18. I saw a lot of banners ____ (hang) from public buildings.

二、單項填空

1. This dictionary is as good as ____ .

    A. neither    B. never    C. any     D. some

〖解析〗這本字典與任何一本字典一樣好，故選C。

2. The hospital is not ____ it was ten years ago .

    A. that       B. as       C. when    D. which

〖解析〗as在此引導(dǎo)表語從句，意為“像……的樣子／那樣”。如:   The  cottage  is just as it was in Shakespeare's time.這幢小屋恰好和莎士比亞時期的一樣。 正確答案為B。

3. The hungry farmer came down to eat the dishes ____ , not even wearing his shoes .

    A. after a short while   B. in a hurry   C. in that case    D. in the way

〖解析〗先看看四個介詞短語的意義，after a  short  while “過了一會兒”， in  a hurry“匆忙地，趕忙地”；in that case“若是那樣”；in this way“用這種方法”。再根據(jù)句中所提供的“the hungry farmer”，“not even wearing his shoes”。 正確答案為B。又如：She came down to breakfast in a hurry , not having brushed  her teeth .

4. To my ____ , the workers set up a carved figure in front of the building .

    A. pleasing    B. pleasure    C. please    D. pleasant

〖解析〗表示“使某人……的是”用“to one's＋情感的抽象名詞”，如to one's  joy/surprise使某人高興／驚奇的是，故正確答案為B。

5. Before ____ the medicine, ____ ought to study the instructions  or  follow a doctor's ____ .

    A. you take, you, advise        B. you take, one, advice

    C. taking, one, advice          D. taking, you, advise

〖解析〗從第三空前的doctor's可知第三空應(yīng)用名詞，不是動詞，故先排除A、D。 若選B，那么從句與主句主語不一致。正確答案為C。

6. It's the third time that Kate has been ill, ____ ?

    A. isn't it    B. hasn't she    C. isn't she    D. hasn't it

〖解析〗陳述部分是主從復(fù)合句，變成附加疑問句時，一般應(yīng)與主句的主語和謂語一致。that Kate has been ill是定語從句。it's是it is的縮寫。故正確答案為A。不過，要提醒同學(xué)們注意的是：當陳述部分的主句是I think, I believe, I guess等結(jié)構(gòu)時時， 附加疑問句要與后面的從句主謂一致。此時， 還要特別注意否定轉(zhuǎn)移現(xiàn)象。 如：I  don't think he is right, is he ?

7. ―What ____ it be ?

― It ____ be a mail box, for it is moving . It ____ be a car .

    A. can, can't, must              B. can, can, must

    C. can, mustn't must             D. must, mustn't can

〖解析〗考查情態(tài)動詞can, must的用法。must在表示“推測”時，只能用于肯定句中， 不能用于否定句中。can表推測時，可用于否定句和疑問句中，故先排除C、D，從for  it is moving，可知第二空應(yīng)填can't（不可能），否則與第三空會自相矛盾。正確答案為A。

8. The fire ____ at 11 last night, but after the firefighters came, it ____ .

    A. was broken out, was died out  B. was broken out, died out

    C. broke out, was died out       D. broke out, died out

〖解析〗英語中有些動詞或短語動詞是不及物的，不能用于被動語態(tài)，同學(xué)們要一一牢記。常見的有：happen, last（持續(xù)），appear, take place（發(fā)生），break out （爆發(fā)），die out（熄滅），belong to（屬于）。正確答案為D。

9. Whether or not it ____ tomorrow, we'll set out on time .

    A. rains    B. rained    C. will rain    D. should rain

    〖解析〗whether or not 意為“是否，無論是不是，不管”，在此引導(dǎo)讓步狀語從句，從句謂語應(yīng)用一般現(xiàn)在時代替一般將來時。如:Whether or not  it  rains, I  will give a party tomorrow.不管下雨不下雨，明天我都要舉行宴會。正確答案為A。

10. My friend John ____ while he ____ his bicycle and hurt himself .

    A. had fallen, rode      B. had fallen, was riding

    C. fell, was riding      D. fell, were riding

    〖解析〗分析句子結(jié)構(gòu)不難發(fā)現(xiàn)，第一空是和and hurt himself并列的，hurt在此時過去式，故第一空填fell。ride在while 引導(dǎo)的從句中表示進行性動作， John 就是在“was riding”中fell的。故正確答案為C。

11. I ____ her if I thought she would understand .

    A. would tell            B. will tell

    C. would have told       D. tell

    〖解析〗這是考查與現(xiàn)在事實相反的虛擬語氣。 條件從句用動詞的過去式， 主句用would＋動詞原形。該句相當于：Because I don't think she  will  understand, I will not tell her .故選A。

12. The reason why she couldn't come to the meeting was ____ .

    A. because she had not been invited        B. which she had not been invited

    C. that she had not been invited                    D. because of her not having been invited

    〖解析〗主句是reason時，其表語從句通常不用because引導(dǎo)，而用that引導(dǎo)。先排除A、D。連接代詞which引導(dǎo)表語從句時，要在從句中擔任成分，因此選項B也不對， 正確答案非C莫屬了。

13. ____ others say, the professor is sure that his theory is correct .

    A. No matter    B. It doesn't matter    C. Whatever   D. What

    〖解析〗Whatever=no matter what 無論什么，whenever=no matter when 無論什么時候；however=no matter how無論怎樣，它們都可引導(dǎo)讓步狀語從句。如：Whatever (= No matter what) you do, don't keep him waiting !無論你做什么，都不要讓他久等！故選C。
