定語(yǔ)從句即用句子來(lái)做定語(yǔ),被修飾或被限制的詞稱作先行詞,例如
1.I don't know the girl who is talking there.
2.I don't know the girl who you met just now.
3.Give me the book that you read just now.
4.Give me the book ,which you read just now.
5.Give me the pen that you write with.
6.Give me the pen with which you write .
仔細(xì)看句子中的book 和pen就是先行詞,他們后面的who that which 就是引導(dǎo)定語(yǔ)從句的關(guān)系代詞,當(dāng)先行詞是人用who,先行詞是物用that,先行詞后出現(xiàn)介詞或逗號(hào)用which.
這是一種捷徑,細(xì)節(jié)問(wèn)題找本語(yǔ)法書慢慢學(xué).
