Question

--- Did Peter come back early last night?
--- Yes. It was not yet eight o’clock _________ he arrived home.

A．when

B．that

C．until

D．before

Answer 1

A

解析試題分析：句意：--皮特昨天晚上回來得早嗎？--是的，還沒有8點他就回來了。這里是when引導的定語從句，先行詞是eight o’clock，關系副詞在從句中狀語，故選A。
考點：考查定語從句的用法。
點評：本題難度適中。定語從句的考查關鍵在于定語從句的成分分析，如果缺少主語，賓語，表語，定語就使用關系代詞，否則，就使用關系副詞。
即學即練：This is one of the best films______ this year.
A. they have been shown       B. that has been shown
C. that have been shown       D. which have been shown
解析：C。先行詞用one of修飾，引導詞用that,并且one of前沒有限制詞，所以從句謂語動詞用have。
