1. She used to help my brother, who was very kind of her.
【改】將who改為which。
【析】犯這類錯(cuò)誤的主要原因是把my
brother錯(cuò)當(dāng)成了先行詞。關(guān)系代詞which指代的先行詞是整個(gè)主句，它引導(dǎo)非限定性定語從句。
2. Do you still remember the day when we spent together in China last year?
【改】將when改為that / which或?qū)?br/> when刪除。
【析】犯這類錯(cuò)誤的主要原因是沒有弄清關(guān)系代詞與關(guān)系副詞的用法區(qū)別。不能因?yàn)橄刃性~表示時(shí)間就一定用關(guān)系副詞when, 而要學(xué)會(huì)準(zhǔn)確把握句子的結(jié)構(gòu)，正確分析句子的成分。例句中定語從句要用關(guān)系代詞引導(dǎo)，并在定語從句中作spent的賓語。
3. The way which you look at problems is wrong.
【改】在which前加in或者將which改為that，也可將which刪除。
【析】當(dāng)先行詞是the way時(shí)，定語從句常用that / in which引導(dǎo)，that / in which也可省略。
4. We were interested in the things and people whom we saw during the trip.
【改】將whom改為that。
【析】當(dāng)先行詞既有人又有物時(shí)，定語從句用關(guān)系代詞that引導(dǎo)，that作賓語時(shí)可省略。
5. It was in the kitchen where the fire broke out.
【改】將where改為that。
【析】犯這類錯(cuò)誤的主要原因是把強(qiáng)調(diào)
句型與定語從句混為一談了。例句為強(qiáng)調(diào)句型，強(qiáng)調(diào)的是地點(diǎn)狀語in the kitchen。
6. Is this factory that you have been working in since your graduation?
【改】在that前加the one。
【析】犯這類錯(cuò)誤的原因是把this factory錯(cuò)看作是定語從句的先行詞了。解答這類題時(shí)，我們不妨先將疑問語序改為陳述語序。this factory是主句的主語，故應(yīng)添加the one作定語從句的先行詞。當(dāng)然，在factory前加the也可以，那么this是主語，the factory是表語。
7. He is such a lazy man as no one wants to work with him.
【改】將him刪除或?qū)s改為that。
【析】犯這類錯(cuò)誤的主要原因是把such ... as ...和such ... that ...兩個(gè)句型混淆了。
8. There are many books in the library, most of which is in Chinese.
【改】將is改為are。
【析】關(guān)系代詞作主語時(shí)，定語從句中謂語動(dòng)詞要與先行詞在人稱和數(shù)上保持一致。例句中關(guān)系代詞which指代的是先行詞books，故從句謂語動(dòng)詞應(yīng)用復(fù)數(shù)形式。
9. I am terribly sorry for having broken the MP4 I borrowed it from you the other day.
【改】去掉it。
【析】定語從句中的關(guān)系代詞在從句中充當(dāng)一定的成分，因此從句中不能再出現(xiàn)與關(guān)系代詞指代相同的代詞或名詞，以避免重復(fù)。例句中it與省略了的關(guān)系代詞that/which重復(fù)，應(yīng)去掉。
10. We will do all what we can to help you out.
【改】改what為that或?qū)hat刪除。
【析】先行詞為指物的不定代詞時(shí)，定語從句用that來引導(dǎo)，that在從句中作賓語時(shí)可省略，而what不能引導(dǎo)定語從句。
11. He is our English teacher, without his help I couldn’t have made such rapid progress.
【改】將his改為whose。
【析】犯這類錯(cuò)誤的主要原因是沒有弄清句子結(jié)構(gòu)。這是一個(gè)主從復(fù)合句，逗號(hào)前面是主句，逗號(hào)后面是“介詞 + 關(guān)系代詞”引導(dǎo)的非限制性定語從句。
12. The scientist has made another discovery, that I believe is of great importance.
【改】將that改為which。
【析】that不能引導(dǎo)非限制性定語從句。
13. There’s somebody that wants you on the telephone.
【改】that改為who或去掉that。
【析】先行詞是-body，-one構(gòu)成的復(fù)合代詞時(shí)，關(guān)系代詞用who (whom)不用that。口語中在It be / there be / here be后面的關(guān)系代詞可省略。
14. John, who greeted me is my teacher, that is deeply respected by all.
【改】me之后加逗號(hào);that改為who。
【析】第一個(gè)who引導(dǎo)的是非限制性定語從句。從句位于句中時(shí)，兩頭須用逗號(hào)與主句隔開。第二個(gè)who引導(dǎo)的也是一個(gè)非限制性定語從句，關(guān)系代詞在指人時(shí)須用who(whom)，在指物時(shí)須用which，不能用that。
15. Do you know the reason why do many people like Zhang Yimou’s films?
【改】去掉why之后的do。
【析】定語從句須用陳述句語序。關(guān)系副詞why在從句中作原因狀語，其先行詞是表示原因的reason。
16. Which is known to all, Mount Emei is one of the famous mountains of China.
【改】Which改為As。
【析】which, as都可作關(guān)系代詞引導(dǎo)非限制性定語從句，表示整個(gè)主句的內(nèi)容，并在從句中作主語、賓語。這種從句放在主句的后邊時(shí)，which, as均可引導(dǎo);放在主句的前邊時(shí)，一般用as引導(dǎo)。
17. Who are the persons who are sitting on the travel bags and which is the bag which belongs to me?
【改】將句中第二who和第二個(gè)which
都改為that。
【析】當(dāng)主句是以who或which開頭的
特殊疑問句時(shí)，為了避免重復(fù)，定語從句要用that引導(dǎo)而不用who (whom)和which引導(dǎo)。
18. The woman who you spoke is an actress.
【改】在spoke之后加to。
【析】關(guān)系代詞who在定語從句中作介詞的賓語時(shí)，介詞須后置。如果介詞to前置，who得變?yōu)閣hom。
19. The number of people lost homes reached as many as 250,000 in the earthquake and the fires in San Francisco in 1906.
【改】在people之后加關(guān)系代詞who /
that。
【析】關(guān)系代詞在定語從句中作主語時(shí)
不能省略。
