    在本單元,同學(xué)們要理解并初步掌握現(xiàn)在進行時被動語態(tài)的用法。現(xiàn)在進行時的被動語態(tài)是由“由be的現(xiàn)在式 (am , is , are ) + being + 過去分詞”構(gòu)成?,F(xiàn)在進行時的被動語態(tài)是表示“某人或者某事此時正在被……”。如:A teaching building is being built in our school .
    【指點迷津】
    單元重點詞匯點撥
    1. deer鹿
    I saw four deer in the forest .
    〖點撥〗deer的單復(fù)數(shù)一樣。單復(fù)數(shù)形式一樣的名詞還有:sheep , aircraft , police , cattle等。
    2. increase增加;繁殖
    Travel increases one’s knowledge of the world .
    The number of tourists has increased . = Tourists have increased in number .
    〖點撥〗增加了百分之幾常用介詞by連接。The population of this town increased by five percent last year .
    另外,on the increase是“不斷增加,正在增加中”。如:Traffic accidents in cities are on the increase this month .
    3.similar類似的
    The two of them are similar in character .
    A cat is similar to a tiger in many ways .
    〖點撥〗be similar to與……相似。又如:Gold is similar in colour to brass (銅) 。
    4. recently近來
    The recently completed , 35-story , four-star hotel is the tallest building in the city .
    〖點撥〗recently在句中時,句子常用現(xiàn)在完成時。如:Have you been very busy recently ?
    5. alive活著的;存在的
    Who’s the greatest man alive ?
    〖點撥〗alive ; living ; live ; lively ; life ; lives 這些詞都有“活著”之意,它們的用法各不相同。
    1)alive 意為“活著”,側(cè)重說明生與死之間的界限,既可指人,也可指物;可用來作表語,后置定語或賓補。雖有死的可能,但還活著。例如:
    The badly wounded soldier was still alive when taken to the hospital .
    He is dead , but his dog is still alive . 他死了,但他的狗仍然還活著。
    No man alive is greater than he . 在活著的人中沒有人比他更偉大了。(注:此時 alive 含有“在所有活著的……之中”)
    He wanted to keep the fish alive . 他想讓魚活著。
    2)living意為“活著”強調(diào)說明“尚在人間”,“健在”,可用來指人或物,作定語或表語。例如:
    Comrade Wang is really a living Lei Feng in our country .
    My first teacher is still living . 我的啟蒙老師仍健在。
    English is a living language . 英語的活的語言。
    A living language should be learned through listening and speaking .
    He is regarded as one of the best living writers at present . 他被認為是當(dāng)代活著的好的作家之一。
    注意:living 前加上 the , 表示類別,指“活著的人們”。例如:The living must finish the work of those dead . 活著的人必須完成那些死去的人的事業(yè)。
    living 還可用于短語,例如:make a living 謀生。
    3)live “活著的”,通常指物,不指人,常用來作定語放名詞的前面。還指“實況轉(zhuǎn)播的”。例如:
    a live wire 有電的電線,a live fish 一條活魚。
    Do you like a live show or a recorded show ? 你是喜歡直播還是錄音 。
    He said he had seen a live whale . 他說他看見過活鯨魚。
    make a / one\'s living by + ing 通過干……謀生
    4)lively 則意為“活潑的”,“活躍”,“充滿生氣的”,可作定語、表語或賓補,既可指人,又可指物。例如:
    Jenny is a lively girl . 詹妮是個活潑的女孩。
    Everything is lively here . 這兒一切都生機勃勃。
    He had a strange way of making his classes lively and interesting . 他有一種奇特的方法,使他的課生動有趣。
    5)life 是名詞作生命可數(shù),作生活不可數(shù)。其復(fù)數(shù)是 lives 。類似把 -fe 變?yōu)?-ves 的還有:wife , shelf , leaf , half , loaf , thief , knife , wolf , self .
    I prefer country life to city life .
    These children are full of life . 這些孩子充滿火力。
    Many people lost their lives in the accident .
    all one\'s life 一生 ,true to life 栩栩如生,in one\'s life 在……的一生中,come back to life 蘇醒過來,live / lead a happy life 過著幸福的生活。
    單元詞組思維運用
    1. make a trip to到……旅行
    They are leaving tomorrow to make a trip to Hangzhou .
    注意:“去……旅行”還可以用take a trip , have a trip , go on a trip , make a journey 。
    2. collect money for= raise money for 為……籌集資金;為……募捐
    These Young Pioneers are trying to collect money for a wildlife protect .
    3. put on performances演出
    You have put on a fine performance .
    The performance put on by the senior class was a dance .
    4. at present= for the time being 目前;現(xiàn)在;如今
    How many research center are there at present for milu deer in China ?
    5. do with處理;對待
    What do people plan to do with the milu deer in future ?
    注意:do with常與what連接使用,deal with常與how連接使用。
    6. too many of太多的
    Too many of the deer had been killed and they disappeared .
    注意:so many和too many的順序。too much修飾不可數(shù)名詞。如:Too much of such rain will ruin the crop .
    7. year by year年復(fù)一年
    They liked the cool wet weather there and their number increased year by year .
    We should do everything possible to enable the peasants to raise their personal incomes year by year .
    注意由“名詞 + by + 名詞”的短語還有:step by step逐步地,two by two兩個兩個地,little by little逐步地。
    8. south of = to the south of在……以南
    The zoo is three miles south of the city . 動物園在城南三英里處。
    Hunan Province lies to the north of Guangdong .
    9. one day總有一天;有一天
    該詞組可以指過去,也可以指將來。但some day指將來。
    One day last summer I made a trip to the country .
    You will come to see the importance of English one day (= some day) .
    10. in the wild在荒野;在曠野
    These animals had to live in the wilds of northwest China .
    11. once more = once again再次;重新
    The facts showed once more that he was not interested in music .

    The students left the theatre one after another after the play . 13. in the past year在過去的一年中
    A lot of work has been done in the past year .
    注意:類似的還有,in the past few years在過去的幾年中,in the last few months在過去的幾個月中。出現(xiàn)這樣的短語時,句子常用完成時態(tài)。而in the past (在過去) 卻需要使用過去時。
    14. be similar to和……差不多,和……相近
    If one thing is very similar to another thing , they look almost the same .
    Cameras are similar to the human eye .
    15. make a study of對……加以研究
    She gave us some advice on how to make a study of teaching methods .
    16. set free釋放
    The girl set the pretty birds free .
    二、學(xué)海導(dǎo)航
    【學(xué)法指要】
    單元難點疑點思路明晰
    1. at present ; at the present time ; for the present
    〖明晰〗這三個短語近義,都可表示“目前;現(xiàn)在”。第一個中的 present 是名詞,其前不用定冠詞;第二個中的 present 是形容詞 ( 意為“現(xiàn)在的 ) ;第三個中的 present 是名詞,其前要用定冠詞。at present 與 at the present time 通??苫Q,而 for the present 側(cè)重指“暫時”。如:At present there are not many milu deer in nature parks in China .
    We use this tense to show that something is being done at the present time .
    For the present we do not need that book , so please go on reading it yourself .
    2 . one day ; some day ; the other day
    〖明晰〗這三個短語都可表示“某一天”,但用法不同。
    ( 1 ) one day 可指過去或?qū)淼哪骋惶?,some day 只能指將來的某一天,the other day 指過去 ( 不久前 ) 的某一天。如:
    At all these centres it is hoped that one day they will have enough animals to set them free and let them live in the wild again .
    You\'ll be an engineer some day .
    I met him the other day at the bus station .
    ( 2 ) 這三個短語通常作狀語用,但 one day 間或能作主語用。如:
    One day on the moon is as long as two weeks on the earth .
    ( 3 ) one day 不能連寫成一個詞。而 some day 有時可連寫成 someday。如:
    Someday we may drive cars that are run by electricity .
    3 . greatly ; very ; much
    〖明晰〗這組副詞都可作“非?!苯猓饕獏^(qū)別是:
    ( 1 ) greatly 修飾動詞或過去分詞。如:
    Since then the number of milu deer there has greatly increased .
    ( 2 ) very 修飾形容詞和副詞原級,不能修飾動詞和 a - 形容詞。如:
    I think he\'s very old .
    ( 3 ) much 修飾動詞、過去分詞、形容詞和副詞的比較級或高級。如:
    We like it very much .
    Now it is much easier to make plans for our trips .
    當(dāng)修飾過去分詞時,much 有時可與 greatly 互換,但 greatly 的語氣比較強。如:
    He was greatly moved .
    4. would like的用法
    〖明晰〗would like 用以表示說話人委婉的愿望或請求。意為“希望,想要”等。其中 would
    ( 適用于各種人稱 ) 可以換成 should ( 只限第一人稱 ) 。在口語中,常用其縮略式“ \'d like”。其否定式為“主語 + shouldn\'t/wouldn\'t like + 其它”;其疑問式為“Would + 主語 + like + 其它 ? ”。would like 主要有如下四種結(jié)構(gòu):
    1) would like +名詞或代詞。
    — Would you like some coffee ? 你要些咖啡嗎 ?
    — Yes , please . 是的。
    — Would you like another cup of tea ? 你還要一杯茶嗎 ?
    — No , thanks . 不要了,謝謝。
    2) would like + 不定式。
    — Would you like to have some rice ? 你要米飯嗎 ?
    — Yes , I\'d like to . 是的,我要。
    — Would you like to have some more beer ? 你還要些啤酒嗎 ? — No . thanks . I\'ve had enough . 不要了,謝謝。我喝夠了。
    — Wound you like to go with me ? 你愿意和我一起去嗎 ?
    3) would like + 主語 + 不定式 ( 作賓補 ) 。
    — Would you like something to drink now ? 你現(xiàn)在想喝些什么嗎 ?
    — I\'d like a glass of beer . 我要一杯啤酒。
    4) would like +不定式的完成式。
    該結(jié)構(gòu)含有責(zé)備或惋惜的意味。表示過去本該做某事但未能去做。
    We\'d like to have helped her . 我們本該幫助她。
    You\'d like to have gone there yesterday . 你昨天本該去那里。
    5. Where are you travelling to , Gary ? 加里,你們打算到哪里旅行 ?
    〖明晰〗該句用現(xiàn)在進行時表示將來,指按計劃、安排在不久就要發(fā)生的動作,常用在口語中。常見的這類動詞有 come , go , leave , arrive , get , start , travel , work , stay , try , fly , return 等。例如:How are you getting there ? 你們打算怎樣到那里。
    6 . Good luck with your trip ! 祝你們旅途好運 !
    〖明晰〗Good luck . 是分手道別時的常用祝愿語,意為“祝幸運/平安/順利”,其后常跟介詞 to ( sb . ) 或 with ( sth . ) 。又如:
    Good luck with your new job !
    Good luck to you !
    7 . Until recently , the only milu deer alive in the world belonged to …直到不久以前,世界上僅有的活著的麋鹿屬于……
    〖明晰〗 ( 1 ) until recently 意為“直到不久以前;直到近”,until 在此相當(dāng)于 till , 其意思是“直到……為止”,可作介詞或連詞,until 在此為介詞。作介詞時,其后常跟表示時間的名詞,也可跟副詞。作連詞時,引導(dǎo)一個時間狀語從句。例如:
    I taught in No . 58 Middle School of Zhengzhou until 1993 .
    Father usually doesn\'t go to bed until very late . 爸爸通常很晚才睡覺。
    ( 2 ) alive 意為“活著的;在世的”,相當(dāng)于 living 或 live ( adj . 活著的 ) ,它屬于
    表語形容詞,即只在句中作表語,不作定語。但 alive 偶爾可以作定語,要放在它修飾的名詞之后。例如:
    Who is the greatest man alive in the world now ?
    living 和 live 作定語時,需前置。例如:living thing 生物,live chicks 活雞
    8 . In fact , there are so many deer that some are being sent to nature reserves by environmentalists who would like to return them to the wild . 其實,現(xiàn)在這種麋鹿已經(jīng)相當(dāng)多了,有一些正在被送往那些愿意把麋鹿送回野外去的地方。
    〖明晰〗 ( 1 ) 該句是一個較為復(fù)雜的復(fù)合句,主句為…there are so many deer , that 引導(dǎo)的是結(jié)果狀語從句,which 引導(dǎo)定語從句。
    在這個 so…that 結(jié)構(gòu)中,中心詞是名詞 deer,本應(yīng)該用 such…that 結(jié)構(gòu),但因名詞前有 many 修飾而用了 so…that 結(jié)構(gòu),此特殊用法需注意。
    ( 2 ) are being sent 是現(xiàn)在進行時的被動語態(tài)形式,表示“正在被送往”其中的 being 容易被誤省。又如本課中的其它兩句:
    The life of the milu deer is being studied there .
    More milu deer are being moved to a new large nature park in Shishou in Hubei Province .
    【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(yī)生一直想在某一家大型的現(xiàn)代化醫(yī)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(xiàn)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(yī)生自然很生氣,于是便給鮮花店打電話詢問怎么回事。
    當(dāng)?shù)昀习迓犝f發(fā)生的情況時,他忙向史密斯醫(yī)生道歉,說是送錯了。
    “ 但真的使我更擔(dān)心的是, ” 他補充道, “ 本應(yīng)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?!?”

    三、智能顯示
    【心中有數(shù)】
    單元語法發(fā)散思維
    一、現(xiàn)在進行時的被動語態(tài)
    〖思維〗1. 現(xiàn)在進行時的被動語態(tài)結(jié)構(gòu)。
    I am/ He / She is/ You / We / They are + being done .
    More milu deer are being moved to a new large nature . 更多的糜鹿正被往一所新建的大天然公園遷移。
    2. 現(xiàn)在進行時的被動語態(tài)的用法。
    A . 表示一個正在進行的被動動作即某件事情現(xiàn)在正在被做。例如:
    The water is being turned into vapour . 水正在變成蒸汽。
    The question is being discussed at the meeting now . 現(xiàn)在會上正在討論這個問題。
    B . 表示在現(xiàn)階段進行被動動作,但不一定發(fā)生在說話的這一時刻。例如:
    The bridge is being repaired .那座橋正在修復(fù)之中。(可指“正在講話的同時”,也可指“目前”。)
    She\'s being taught English . 有人在教她英語。(在說話時,也許根本沒人教她。)
    [注]現(xiàn)在進行時的被動語態(tài)有時可與情態(tài)動詞連用。如:
    I know Mark was going to have an interview sometime this afternoon . He may be being interviewed at this very moment . 我知道馬克今天下午什么時候有面試。他此刻也許正在接受面試哩。
    練習(xí):
    A . 把下列句子變成被動語態(tài)。
    1 . Mr Smith is driving a car .
    2 . The teacher is scolding (批評) me .
    3 . They are painting the houses .
    B . 單項選擇。
    4 . — Have you moved into the new house ?
    — Not yet . The rooms ____ .
    A . are being painted B . are painting C . are painted D . are being painting 5 . I ____ English for five years now .
    A . was studying B . have been studying C . studied D . am studying
    6 . The blood ____ now .
    A . is tested B . is being testing C . is being tested D . has been testing
    7 . The new lake ____ in the park , so many workers are working there .
    A . is made B . has been being made C . is being making D . is being made
    8 . In some parts of the world , tea ____ with milk and sugar .
    A . is serving B . is served C . serves D . served
    答案:1. A car is being driven by Mr Smith . 2. I am bing scolded by the teacher . 3. The houses are being painted . 4 — 8 ABCDB
    二、enough 與高考
    Ⅰ . enough 作副詞用時,可修飾形容詞、副詞和動詞。修飾形容詞、副詞時,enough 應(yīng)后置。
    Helicopters were sent to rescue them , but it was impossible for them to get close enough .
    When they reached the burning building they found that their ladders were not long enough to reach the people who were trapped .
    You don\'t practise enough at the piano .
    I with you\'d write clearly enough for us to read it .
    Ⅱ . enough 作形容詞用時,修飾復(fù)數(shù)名詞和不可數(shù)名詞,習(xí)慣置于名詞之前。
    Have you made enough copies ?
    I\'ll get enough money to pay for a taxi .
    當(dāng) enough 和形容詞一起位于名詞之前時,要注意辨別 enough 的詞性以及對語義的影響。比較:
    1 . a) I haven\'t found enough big nails to mend the cupboard . 我還沒找到足夠的大釘子來修碗柜。
    b) I haven\'t found big enough nails to mend the cupboard . 我還沒找到足夠大的釘子來修碗柜。
    a) 句中的 enough 是形容詞,修飾 nails,強調(diào)釘子的數(shù)量。b)句中的 enough 是副詞,修飾 big,強調(diào)釘子的大小。
    2 . a) Is there enough hot water for me to have a bath ? 有足夠的熱水讓我洗個澡嗎 ?
    b) Is there hot enough water for me to have a bath ? 有足夠熱的水讓我洗個澡嗎 ?
    a) 句中的 enough 是形容詞。修飾 water , 強調(diào)數(shù)量;b)句中的 enough 是副詞,修飾 hot , 強調(diào)水的溫度。
    下面請看 NMET1998 — 11題。
    If I had _______ , I\'d visit Europe , stopping at all the small interesting places .
    A . a long enough holiday B . an enough long holiday
    C . a holiday enough long D . a long holiday enough
    選項A中的 enough 是副詞,修飾 long,強調(diào)程度,符合句意,故是佳句意,故是佳答案。B中的 enough 是形容詞,不能修飾單數(shù)可數(shù)名詞,故不選。選項C、D的語序不對,也不可選。
