4. 當指物的關系代詞被指人的短語隔離時。例如：
the cat beside the girl which is lovely was bought yesterday.
二、 先行詞為人時，who與that的區別。
1. 當先行詞在從句中作表語或主句是以who引導的特殊疑問句時，關系詞用that。例如：
he isn’t the man that he used to be.
who is the man that is standing there?
2. 若先行詞為he, she, those, anyone等表示一類人的詞時，關系詞一般用who。例如：
he who invited me to the party is my brother.
anyone who wants to see the film please let me know.
（三）it takes/took （+間接賓語）+直接賓語+to-v.
it took him two hours to finish his homework.
it takes ten minutes to get to tiananmen from wangfujing by bike.
take 與 spend 的辨析
take 與spend 都可以表示“花費”的意思，但用法結構不同。
spend的主語必須是“人”，賓語可以是“時間”、“金錢”，后面用on接名詞，用in接動名詞，in通常可以省略。
he spends fifty yuan on his bag.
he spends two hours （in） doing his homework.
（四）since 的用法
since 指時間時，可作副詞、介詞、連詞。無論作何詞性，since 總和完成時連用。
1）作副詞。前文通常有一個過去時間與之相呼應，強調從那時到現在一段時間里。
he went to school three years ago and has studied here since.
他三年前上學，從那以后就一直在這里學習。
2）作介詞時后接表示時間點、每一活動或每一情況的名詞，不能接時間段名詞。
i haven’t met him since last year.
我從去年以來就沒遇見過他。
3）作連詞時可以引導時間狀語從句和原因狀語從句。
