Question

Was it ______ he was playing volleyball on the playground_________ he got hurt?

A．that; when	B．when; that
C．that; where	D．where; that

Answer 1

B

试题分析：这是强调句型，其结构是：It was+被强调部分+that/who+其他。判断强调句型的方法是把It was that这三个词去掉，整个句子不缺成分，意思完整。这里被强调部分是时间状语从句when he was playing volleyball on the playground，故选B。
点评：本题较难。强调句型是高中阶段的重难点之一，也是高考的热点，需要考生有分析理解句子的结构的能力。尤其把强调句型与其他从句混合在一起考查更增加了试题的难度。
即学即练：Itwas not until midnight______they reached the camp site.
A. that    B.when   C.while   D. as
解析：A。该题强干扰项是B，考生容易因强调时间状语untilmidnight而误选。
