在本句中，先行詞是the man;關(guān)系代詞whom/that 引導(dǎo)定語從句，同時代替先行詞在從句中擔(dān)任動詞want 的賓語。

　　Is he the manager (whom/that) you are looking for?

　　他是你在找的那位經(jīng)理嗎?

　　(3)當(dāng)關(guān)系代詞緊跟介詞作介詞賓語時，不能用that，也不能省略，

　　如：The book from which I got a lot of useful information was written by a famous scientist.

　　我從中得到許多有用信息的那本書是一位著名科學(xué)家寫的。

　　Who is the boy with whom you were talking a moment ago.

　　你剛才和他說話的那個男孩是誰?

　　I know the young couple from whose house the music is coming.

　　但是當(dāng)介詞放在從句末尾時，作為介詞賓語的關(guān)系代詞可以用that 并且可以省略。

　　如上頭兩句可改為：

　　The book (that /which) I got a lot of information from was written by a famous scientist.

　　Who is the boy (that/whom) you were talking with a moment ago?

　　2.指物的關(guān)系代詞which和that的用法：

　　(1)作主語

　　This is the instruction manual which/that tells you how to operate the computer.

　　這是那本教你如何操作計算機的說明手冊。

　　(2)作賓語包括作介詞賓館。此種情況下的關(guān)系代詞可以省略：

　　The chair (which /that) you broke yesterday is now being repaired.

　　你昨天弄壞的那把椅子現(xiàn)在正在修理。

　　The film (which/that) I saw last night was about a soldier who fought in WWII.

　　我昨天晚上看的那部電影是關(guān)于一個在二戰(zhàn)中打過仗的士兵的。

　　(本句有兩個定語從句。)

　　This is the bike for which I paid $ 100.

　　這就是我花了100美元買的那輛自行車。

　　The car(which/that)he went in was a black Cadillac.

　　他坐在里面走了的那輛汽車是一輛黑色的卡迪拉克。

　　The accounts of the company, (which/that) I’ve been paying great attention to, are in balance.

　　我一直非常注意的公司賬目，是保持平衡的。

　　3.whose 和of which 指代人或事物，作定語。of which 可用whose 代替;

　　The car whose lights (of which the lights/the lights of which) were all broken was my father’s.

　　那輛所有的燈都破了的汽車是我父親的。

　　例：His house of which the windows (the windows of which /whose windows) were all broken was a depressing sight.
