Question

It's on the festival occasions________ the family get together________ he misses his late father.

A．where; that

B．which; when

C．when; that

D．that; when

Answer 1

C

试题分析：句意：每当过节家人团聚的时候，他就会想念他的父亲。该句为强调句型，被强调部分为on the festival occasions，但该部分后又加上了一个定语从句，先行词是occasions，在定语从句中作时间状语，故用关系副词when引导。故选C。
点评：本题难度适中。定语从句及强调句型是高中阶段的重难点，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：It was two decades ago ______  I was in my teens ______the Chinese government decided to reform the social economic system.
A. when; when    B. that; which     C. when; that    D. before; that
解析：C。考查定语从句和强调句的混用。when引导时间状语从句，强调句型It was ...that对when引导的从句进行强调，故选C。
