    The Attributive Clause定 語 從 句
    一、定義:用來修飾名詞或代詞的句子叫做定語從句
    被修飾的名詞、詞組或代詞稱為先行詞;
    二、關(guān)系詞和先行詞的關(guān)系:
    關(guān)系詞和先行詞密切相關(guān),因為關(guān)系詞用來指代先行
    詞,并且在從句中充當(dāng)一定的成分。常用的關(guān)系詞有:
    關(guān)系代詞:who / whom (先行詞表示人)
    which (先行詞表示物)
    that / whose (先行詞表示人或物)
    關(guān)系代詞在從句中可充當(dāng)主語,賓語或定語;
    可以和介詞連用的關(guān)系代詞:whom, which
    關(guān)系副詞: when=on+which (表示時間)
    where =in+which(表示地點)
    why=for+which(表示原因)
    注意:關(guān)系副詞在從句中充當(dāng)狀語。
    三.按關(guān)系詞種類再學(xué)習(xí)
    1.由that引導(dǎo)的定語從句
    一般情況下that可指人或物,可以代替who,whom和which,但不能置于介詞之后,如不能用in that, 只能是 in which。如:The letter that(which)I received yesterday was from my father.
    2.由who,whom和whose引導(dǎo)的定語從句
    who在從句中作主語,有時也可以代替whom做賓語;whom在從句中作賓語;whose在從句中作定語。如:
    1) This is the thief who stole my bike.
    2)He is the boy whom you wanted to find.
    3) The girl whose mother is a doctor is waiting for you outside.3.由which引導(dǎo)的定語從句
    which指物,在從句中作主語或作謂語動詞的賓語。如:
    1)The book which Mum bought me last week is very good.
    2) The house which was built last year belongs to them.
    4.由where,when和why引導(dǎo)的定語從句
    where在從句中作地點狀語,when在從句中作時間狀語,why在從句中作原因狀語。如:
    1) I will never forget the day when ( on which ) I joined the League.
    2) He will go back to the school where (in which ) he studied next week.
    3)I don't know the reason why (for which) he quarreled with Zhang Lin.
    四.注意點
    (1)關(guān)系代詞在定語從句中作賓語時,關(guān)系代詞常省去。
    如:The play(which)I watched just now had been on twice on Channel 3.
    (2) 當(dāng)定語從句中含有介詞,介詞放在句末時,who, that, which可省略,但介詞在關(guān)系代詞前時,只能用“介詞+which/whom”結(jié)構(gòu)。
    如:This is the house (that/ which )we lived in last year.= This is the house in which we lived last year.
    (3)關(guān)系代詞在定語從句中作主語時,從句謂語動詞的人稱和數(shù)要和先行詞保持一致。
    例如:The boys who are playing football are from Class One.
    (4)注意定于從句中,先行詞與關(guān)系代詞可合成what 的用法 :
    Please tell me what you said just now. = Please tell me the things that you said just now.
    He showed me what he had written. = He showed me the things that he had written.
    可以看到部分定語從句中,先行詞+關(guān)系詞 可以換作what。
    (5)關(guān)系詞只...
