Question

Tom hid himself behind the door, _________ he could hear the steps of his mother clearly.

A．from which

B．from where

C．where

D．which

Answer 1

B

試題分析：句意：湯姆把自己躲藏在門后面，從那里他能清楚地聽到他母親的腳步聲。where表地點(diǎn)，在這里代替 behind the door，做介詞from的賓語，相當(dāng)于from behind the door，which是關(guān)系代詞，那一個，代替是物的先行詞，作主語、賓語或者表語。選擇定語從句關(guān)系詞的一個依據(jù)是，看關(guān)系詞在從句中所做的成分。故選B。
考點(diǎn): 考查定語從句的用法。
