2、irl beautiful是形容詞做定語一本有趣的書a book that is interesting 從句做定語（book是先行詞）等于an interesting book 形容詞做定語復合句中，修飾某一名詞或代詞的從句叫做定語從句。既這個從句起的作用與形容詞完全一樣，起修飾和限定主句里名詞的作用?？梢孕稳萑耍锖褪录谥骶渲谐洚敹ㄕZ的作用。試比較：I like quiet music.I like music that is quiet.定語從句要跟在所修飾的名詞或代詞后面，被定語從句修飾的名詞或代詞叫做先行詞。定語從句一般用關系代詞who，that，which和whose來引導，放

3、在從句的句首使從句與主句相連，并在句中擔當一定的成分，關系代詞如果在從句中作主語就要用主格，如果做賓語就要用賓格，如果做定語就要用所有格。I like music that I can dance to. 我喜歡可以隨之跳舞的音樂。music作先行詞，that I can dance to 是定語從句修飾music，其中，that是關系代詞引導定語從句I prefer singers who can write their own songs. 我喜愛能自己寫歌的歌星。singers作先行詞，who can write their own songs 是定語從句修飾singers，其中，who

(作賓語)指人1.Who is the man that is reading the book over there? (作主語)2.The girl (that) we say yesterday was Jims sister. (作賓語)Who / that 在定語從句中做主語時，需

(作主語)2.The songs （which） Liu Dehua sang were very popula

6、r. (作賓語)Who, whom在從句中分別作主語和賓語（若介詞放在從句后面，則whom可以省略）指人1.The foreigner who visited our class yesterday is from Canada. (作主語)2.The boy who break the window is called Roy.
