一、考查結構詞的選擇與使用
強調句的基本結構是“It+be+被強調成分+that (who)...”，其中的結構詞it和that (who)為高考英語考查強調句時最常考查的考點。如：
1. I don't mind her criticizing me, but _____ is how she does it that I object to. (江西卷)
A. it B. that C. this D. which
【解析】答案選A。此題考查it is ...that...這一強調句句型。句意為：我不介意她批評我，我反對的是她批評我的方式。句中空格處填強調句結構詞it。
2. It is not who is right but what is right ___C___ is of importance. (重慶卷)
A. which B. it C. that D. this
【解析】答案選C。此題考查it is...that...這一強調句式，被強調的是not who is right but what is right，全句意為：重要的不是誰是對的，而是什么才是對的。句中空格處填強調句結構詞that。

二、考查強調句的特殊疑問句形式
強調句型的陳述句形式和一般疑問句形式一般還好理解，但若以特殊疑問句形式出現，則很容易誤解。比較：
Jim told us the news.（非強調句）
It was Jim that told us the news.（強調句型的陳述句形式）
Was it Jim that told us the news?（強調句型的一般疑問句形式）
Who was it that told us the news?（強調句型的特殊疑問句形式）
特殊疑問句形式的強調句可視為對陳述句強調中的被強調成分提問得來，如對It was yesterday that he arrived. 這一句中的yesterday提問，即得到When was it that he arrived?

1. I just wonder _______ that makes him so excited. (山東卷)
A. why it does B. what he does C. how it is D. what it is
【解析】答案選D。注意what it is that makes him so excited為賓語從句，用作動詞wonder的賓語。如果去掉主句I just wonder將原句改為疑問句則是：What is it that makes him so excited?
2.— _____ that he manage to get the information?
—Oh, a friend of his helped him. (山東卷)
A. Where was it B. What was it C. How was it D. Why was it
【解析】答案選C 。由答語的內容可知，空格處應填how。
