1.指人的關(guān)系代詞：who, whom, whose, that 的用法：
    (1)作主語(yǔ)(who, that )
    Those who are going to play in the match are to meet at the gate at 1:30 after lunch. 那些參加比賽的人午飯后1：30在大門口集合。
    在本句中，先行詞是those;關(guān)系代詞who引導(dǎo)定語(yǔ)從句，同時(shí)代替先行詞在從句中擔(dān)任動(dòng)詞are going to play 的主語(yǔ)。
    The man who/that is talking with Mr. Wang is a famous doctor. 正在和王先生說(shuō)話的那個(gè)人是一個(gè)有名的醫(yī)生。
    在本句中，先行詞是the man;關(guān)系代詞who/that引導(dǎo)定語(yǔ)從句，同時(shí)代替先行詞在從句中擔(dān)任動(dòng)詞is talking的主語(yǔ)。
    這個(gè)復(fù)合句可以還原成兩個(gè)句子：The man is a famous doctor. He is talking with Mr. Wang.
    (2)作賓語(yǔ)包括作介詞賓語(yǔ)(whom, that )。此種情況下的關(guān)系代詞可以省略;
    This is just the man(whom/that) I want for the job.這正是我要的做這份工作的人。
    在本句中，先行詞是the man;關(guān)系代詞whom/that 引導(dǎo)定語(yǔ)從句，同時(shí)代替先行詞在從句中擔(dān)任動(dòng)詞want 的賓語(yǔ)。
    (3)當(dāng)關(guān)系代詞緊跟介詞作介詞賓語(yǔ)時(shí)，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科學(xué)家寫的。
    但是當(dāng)介詞放在從句末尾時(shí)，作為介詞賓語(yǔ)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.
    2.指物的關(guān)系代詞which和that的用法：
    (1)作主語(yǔ)
    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(jì)算機(jī)的說(shuō)明手冊(cè)。
    (2)作賓語(yǔ)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 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(yǔ)。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。
