練習(xí)�。╱nit 5）
19. 單句改錯
1.The baby after whom she is looking is my little nephew.
簡析：after應(yīng)置于looking之后，短語動詞look after不能拆開。
2.I saw all the apples which were on the table fall off into the floor.
簡析：應(yīng)將which改為that。當(dāng)先行詞被all, any, few, little, no等詞修飾時，關(guān)系代詞應(yīng)選用that, 不能用which。
3.The speaker raised his voice but still couldn’t make himself hearing.
簡析：應(yīng)將hearing改為heard。make oneself heard意為“讓別人聽到自己的聲音”�！癿ake oneself+過去分詞”結(jié)構(gòu)中，過去分詞作賓語補(bǔ)足語，賓語oneself與賓補(bǔ)之間是被動關(guān)系。
4.This is the only bus which there is to the village.
簡析：將“which”改為“that”。在這個句子中，that there is to the village是定語從句，是there be句型，修飾其先行詞bus。而且先行詞bus被the only修飾。bus在定語從句中作主語，to the village也作bus的定語。整個句子意為“這是惟一通往那個村莊的一輛汽車”。
20. 高考真題
1.(NMET 1998)Cleaning women in big cities usually get ___________ by the hour.
A. pay B. paying C. paid D. to pay
簡析：選C。“按小時付報酬”與主語是被動關(guān)系，應(yīng)選過去分詞paid。類似的表達(dá)常見的還有：get burnt, get wounded, get married等。
2. (NMET 1998)European football is played in 80 countries, ___________it the most popular sport in the world.
A. making B. makes C. made D. to make
簡析：選A。本句意為“八十多個國家都踢歐式足球，這使其成為世界上最流行的運(yùn)動”。此處應(yīng)選現(xiàn)在分詞作狀語。此題可用排除法來考慮；不表目的，不用不定式，排除D；不是完整的句子，不用謂語動詞，排除B。其后跟有賓語和賓語補(bǔ)足語，不可能是被動的，排除C。特別要注意make后接復(fù)合賓語這種句型。
3. (2001 上海)He’s got himself into a dangerous situation ___________he is likely to lose control over the plane.
A. where B. which C. while D. why
簡析：選A。此題考查定語從句中關(guān)系副詞的用法。定語從句的先行詞為situation，引導(dǎo)從句的詞在定語從句中作狀語，因此這個復(fù)合句中的定語從句應(yīng)由關(guān)系副詞where引導(dǎo)。
4. (NMET 2001春招)Would you slow down a bit, please? I can’t ___________you.
A. keep up with B. put up with C. make up to D. hold on to
簡析：選A。此項中的短語keep up with含義為“跟上，趕上”，從上文的提示“讓對方慢下來一點”，體會出是“跟不上對方”，故選A。
5. (NMET 2001)The film brought the hours back to me ___________I was taken good care of in that far-away village.
A. until B. that C. when D. where
簡析：選C。通過分析句子結(jié)構(gòu)，可以看出這是一個包含定語從句的復(fù)合句。先行詞是the hours，引導(dǎo)詞在定語從句中作狀語，因此要用when來引導(dǎo)此定語從句。有時命題者會在先行詞與引導(dǎo)詞之間加入附加成分，影響考生正常的解題思路，需特別注意。
Unit 6 能力訓(xùn)練
1. 單句改錯
1.It’s time for us to clean the desks. But we can’t find any clothes.
簡析：把clothes改為cloths。cloth作不可數(shù)名詞時，是“布匹”的意思，它作可數(shù)名詞時表示有特殊用途的布，其復(fù)數(shù)形式為cloths,而clothes是“衣服”的意思，不符合本句意思，故改為cloths表示“擦桌布”。
2.He prefer swimming to play football in summer.
簡析：將play改為playing。prefer A to B 等于like A better than B，即喜歡A勝過喜歡B，prefer+名詞/動名詞+to+名詞/動名詞，to 為介詞，故不能接動詞原形。
3.The girl students in our school are not allowed wearing high-heel shoes.
簡析：把wearing改為to wear。allow可接帶不定式的復(fù)合結(jié)構(gòu)，“allow sb.to do sth.”表示“允許某人做某事”，其被動式應(yīng)為“sb.be allowed to do sth.”。另外，allow可跟動名詞作賓語，構(gòu)成allow doing sth.表示“允許做某事”，此結(jié)構(gòu)不可用于表達(dá)該句意義。
4.My house is quite close from the station.
簡析：把from改為to。表示“接近于……”，應(yīng)該是“be close to”，而不用“be close from”。
5.I apologize you that I had been so rude to you.
簡析：此句應(yīng)為I apologize(to you) for being so rude to you.
表示“為某事向某人道歉”用apologize to sb.for sth./doing sth.,不能用that引導(dǎo)從句。
2. 高考真題
1.(2000上海，42)-You’ve given us a wonderful Chinese dinner, Mrs.Wang.
-___________.
A. Oh,I’m afraid I didn’t cook very well B. I’m glad you enjoyed it
C. Come again when you are free D. It’s not necessary for you to say so
簡析：選B。此題要注意兩種文化背景的不同而帶來的行為習(xí)慣的差異。
2. (2000上海)-I don’t have any change with me. Will you pay the fare for me?
-___________.
A. That’s fine B. Nothing serious C. Never mind D. No problem
簡析：選D。D是回答別人的請求的用語，相當(dāng)于“沒問題”。
3. (NMET 2000春)It was an exciting moment for these football fans this year,___________for the first time in years their team won the World Cup.
A. that B. while C. when D. which
簡析：選C。此處是非限制性定語從句，排除while(不引導(dǎo)定語從句)和that(不引導(dǎo)非限制性定語從句)。關(guān)系詞在從句中作時間狀語，要用關(guān)系副詞when，而不用關(guān)系代詞which。
4. (NMET 2000)Dorothy was always speaking highly of her role in the play, _____,of course, made the others unhappy.
A. who B. which C. this D. what
簡析：選B。“of course”是插入語，略去不管則可看出，此處是個非限制性定語從句，需添一個關(guān)系詞，排除this 和what。又因先行詞是事情“always speaking highly of her role in the play”,因此用which,而不用who。
5. (NMET 2001春)John said he’d been working in the office for an hour,___________was true.
A. he B. this C. which D. who
簡析：選C。此處是非限制性定語從句，需用關(guān)系代詞，排除A. he和B. this。先行詞不是“人”(不是說“約翰是真的”)，排除C. who。先行詞是事物(是說“he’d been working in the office for an hour”是真實情況)，關(guān)系代詞用which。
6. (NMET 2001春)-Why haven’t you bought any butter?
-I___________to but I forgot about it.
A. liked B. wished C. meant D. expected
簡析：選C�！癿ean to (buy some butter)”表示“本意是(要買些黃油)”，用了過去式表示“原打算”，此處將不定式省略，只留了不定式符號“to”。“l(fā)ike to do sth. ”是“喜歡干某事”；“wish to do sth. ”是“希望做某事”；“expect to do sth. ”是“預(yù)計干某事”都與上下文題義不合。
