高一册第19单元的语法重点是it在强调句型中的用法，这也是高考的重要考点。为了强调句子某一成分(除谓语外)，将这一成分置于"It is (was)... that (who)..."这一句型中is (was) 之后，如果强调部分是人，既可用that又可用who连接，其余的全用that。这一句型也可用于一般疑问句、否定句和特殊疑问句。其特点是：去掉It is (was) 及 that (who)这几个标志词之后，在不添词、不减词的前提下能重新排列成一个完整的句子。现通过分析高考试题，体会it在强调句型中的用法，以期对同学们有所帮助。

　　A. it you B. not you

　　C. you D. that yourself
