强调句子的区别和用法。

22．It's his brother ________ never been to Australia. You'd better take him with you.

A. that is

B. who is

C. that have

D. who has

【答案】 D

【解析】【分析】句意：是他的弟弟从没去过澳大利亚，你最好带他跟你去。have been to 去过……。强调句型是：It is+被强调部分+that（指人时用who）+句子的其他成分。此处强调句子的主语his brother，故谓语用has。因此选D。

【点评】考查强调句型。

23．It's a long time ago ______ I saw you last time.

A. when

B. since

C. for

D. that

【答案】 D

【解析】【分析】句意：我上次见你是很久以前了。强调结构It is…that…，本句中it没有实际含义，和is,that构成框架，强调谓语以外的部分，去掉它们句子仍然成立。故选D。【点评】本题考查的是强调句型结构。强调句型是对句子的主语，宾语，状语等进行强调，（谓语除外），其基本结构是It is +被强调的部分+that/who+句子的其他成分（强调主语若是人引导词可以用who/that,若是其他一律用that ）。去掉这个框架结构句子仍然成立。

【点评】对于强调句中强调主语时应注意，如果不加分析可能会选择them。这在平时的学习中一定要注意分析。
