定語從句

在句中做定語，修飾一個名詞或代詞，被修飾的名詞詞組或代詞即先行詞。定語從句通常出現(xiàn)在先行詞之后，由關(guān)系詞（關(guān)系代詞或關(guān)系副詞）引出

。關(guān)系代詞有：who,whom,whose,that,which等。關(guān)系副詞有：when,where,why等。二、用法

1、關(guān)系代詞引導(dǎo)的定語從句

關(guān)系代詞所代替的先行詞是人或物的名詞或代詞，并在句中充當(dāng)主語、賓語、定語等成分。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。先行詞：是被定語從句所修飾的詞（通常是名詞或代詞）

關(guān)系詞的作用：1.引導(dǎo)定語從句2.在從句中替代先行詞，在定語從句中充當(dāng)一定的成分，通常是主語或賓語，作賓語時?？梢允÷?。定語從句：先行詞+關(guān)系詞(that/which/who)+從句修飾a)他就是我昨天見到的那個人。①Heistheman.②Isawhimyesterday.HeisthemanwhomIsawyesterday.b)你認(rèn)識站在那邊的那個人嗎？①Doyouknowtheman?②Heisstandingoverthere.Doyouknowthemanwhoisstandingoverthere?（）
