16、t。强调主语时，that后的谓语动词必须与被强调的主语在人称与数上保持一致。(1)该句型为强调句型。判断方法：将It is/wasthat/who 去掉，看剩下的部分是否仍然完整。若完整，则是强调句型；若不完整，则为状语从句、定语从句或主语从句。(2)强调主语或宾语且其为人称代词时，应注意其形式仍用主格或宾格形式。(3)强调主语时，that或who后面的谓语动词必须和主语在人称和数上保持一致。【句式分析】(1)I(确实向你讲述了这件事)yesterday.(2)It(玩电脑游戏)that cost theboy a lot of time he ought to have spent on h

19、 her first school,which inspires everyone to help her.A.where;when B.that;thatC.that;when D.where;that解析：选D。句意为：就是在那个她生活和工作了15年的贫穷的村庄，玛丽将要建起她的第一座学校，这一点鼓舞了人们来帮她。第一空为where引导的非限制性定语从句，第二空填that,构成强调句型，强调地点状语。（2）特殊句式中的强调句型：如果强调的是特殊疑问句中的疑问词，表示“到底”、“究竟”等语气时，就用如下结构：“特殊疑问词+is/was+it+that/who+该句的其余部分”，that/wh

20、o后只能使用陈述语序。在“not.until”结构中，由until所引导的短语（或从句）作时间状语时，要用固定的强调句型：“It+is/was+not until.+that+该句的其余部分”，that所引导的从句中的谓语动词用肯定式。（3）强调句型要注意和it代表时间、距离、温度、自然现象、具体事物或人物等时所构成的各种句型的区别。判断是否是强调句，可采用“还原法”。如果还原为一般句式后，句子各种成分完整，则是强调句，否则不是。It was three oclock when I got home.我到家的时候三点。It was at three oclock that I got home

21、.三点钟我到的家。It was in his town that he was brought up.他是在镇上被养大的。（强调句）It was this town where/in which he was brought up.这是他被抚养长大的城镇。（定语从句）1.It is I who/that _ right.A.is B am C.are2._was in 2003_ I graduated from the university.A.That;that B.It;that C.That;when D.It;when 3.Was _ that I met last night in
