There is a room, whose window faces the is a room, the window of which faces the 、關系代詞as,在從句中作主語、賓語和表語。（1）先行詞被such和the same修飾，或句型as many（much）中，從句都用as 引導。Such books as you bought are school is just the same as it was 10 years ：區(qū)別①such ? that ? 引導的結果狀語從句。They are such lovely children that we love them much.②the same ? that ? 引導定語從句。I want to use the same tool that you used just now.（2）無先行詞的定語從句用as和which引導。區(qū)別：①意義上：as 含有“這點正如??一樣”。②位置上：as 從句可置句首，也可在另處。He didn’t pass the exam, as we had 愛心 專心There is lots of air in loose snow, which can keep the cold is known, the earth is round, not 、關系副詞when與where、why、that when 指時間 = in / at / on / during which where指地點 = in / at / from / which why指原因 = for which 當先行詞為way、day、reason、time時，可用that作關系副詞。（非正式場合）I don’t like the way that / in which / he ，關系詞可以省掉。This is the first time I have given you a lesson in 、必須注意的問題（1）關系詞作主語時，從句中謂語的數(shù)。（2）注意區(qū)別定語從句與強調(diào)句。①定語從句中關系詞作從句成分，復合句。②強調(diào)it無意義，that / who不是引導詞。③強調(diào)it is / was和that / who后如果句子意思講得通則是強調(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定語從句引導詞被稱為關系詞，that充當主語、賓語、表語。有時可省略。②同位語從句引導詞被叫做連詞，that不能充當任何成分，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）關系詞在從句中省略的情況。①關系詞作賓語，前無介詞時。②關系詞作表語。（5）限制性定語從句與非限制性定語從句的翻譯。（6）關系詞前有介詞或復雜介詞，關系詞只能是which和whom。（7）幾個特殊的定語從句句型：①He is the only one of the students who has got very good marks用心 愛心 專心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?
