Question

I notice Linda is often absent from school because of illness. _______ she is not so healthy as she used to be?

A．Why is it that

B．Is it why that

C．Why is

D．Is it why

Answer 1

A

试题分析：句意:我注意到琳达经常因为生病而旷课，为什么她不如以前健康了呢？这里是强调句型，其结构是：It is/was+被强调部分+that/who（人）+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。这里被强调的是疑问词why，因为有特殊疑问词的强调句型结构为：疑问词+be it+that +其他。故选A。
点评：本题难度适中。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。尤其把强调句型变成疑问句时考查更增加了试题的难度。
即学即练: It was 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until midnight而误选。
