（1）關(guān)系詞作主語時(shí)，從句中謂語的數(shù)。

（2）注意區(qū)別定語從句與強(qiáng)調(diào)句。

　?、俣ㄕZ從句中關(guān)系詞作從句成分，復(fù)合句。

　　②強(qiáng)調(diào)it無意義，that / who不是引導(dǎo)詞。

　?、蹚?qiáng)調(diào)it is / was和that / who后如果句子意思講得通則是強(qiáng)調(diào)句，講不通則不是。

　　It is the museum that / which we visited last year.(定語從句)

　　It was in the hotel that we stayed last night.（強(qiáng)調(diào)句）

（3）定語從句與同位語從句的區(qū)別。

　　①定語從句引導(dǎo)詞被稱為關(guān)系詞，that充當(dāng)主語、賓語、表語。有時(shí)可省略。

　　②同位語從句引導(dǎo)詞被叫做連詞，that不能充當(dāng)任何成分，不可省。

　　Word came that their army was defeated.(同位語)

　　We expressed to them our wish that was the same as their.(定語)

（4）關(guān)系詞在從句中省略的情況。

　?、訇P(guān)系詞作賓語，前無介詞時(shí)。

　　②關(guān)系詞作表語。

（5）限制性定語從句與非限制性定語從句的翻譯。

（6）關(guān)系詞前有介詞或復(fù)雜介詞，關(guān)系詞只能是which和whom。

（7）幾個(gè)特殊的定語從句句型：

　?、貶e is the only one of the students who has got very good marks in the match.（句中one為先行詞）

　　He is one of the students who have got good marks in the match.（句中students為先行詞）

　　②Is this place the one (that) we visited yesterday?

　　Is this the place(that / which)we visited yesterday ?

　?、跦e stood at the window, from where he could see what was happening.

　　④It may rain, in which case the match will be put off.
