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

解析试题分析：句意：--皮特昨天晚上回来得早吗？--是的，还没有8点他就回来了。这里是when引导的定语从句，先行词是eight o’clock，关系副词在从句中状语，故选A。
考点：考查定语从句的用法。
点评：本题难度适中。定语从句的考查关键在于定语从句的成分分析，如果缺少主语，宾语，表语，定语就使用关系代词，否则，就使用关系副词。
即学即练：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。先行词用one of修饰，引导词用that,并且one of前没有限制词，所以从句谓语动词用have。
