it引导的强调句型


英语中的 it 强调句型
一、it 强调句型的构成: It+be+被强调部分+that(强调部分指人做主语时时用 who,指人做宾语时用 whom)+句子 的其他部分。 例如: Mary met an old beggar in the street yesterday. It was Mary who/that met an old beggar in the street yesterday. It was an old beggar whom/that Mary met in the street yesterday. It was yesterday that Mary met an old beggar in the street. It was in the street that Mary met an old beggar yesterday. 注意:it 强调句型不能强调句子的谓语。 二、not…until 结构强调句型的构成: It+be+not+until 部分+that+句子的其他部分。 例如: He didn't go to bed until his father came back.. 变为强调句型为: It was not until his father came back that he went to bed.注意原句中的 didn't go 部分中的 not 提前后,剩下 did go 变为 went. 本文开头提到的两个句子都是 not..until 结构用于强调句型。那么把这两句话变回正常 的语序则为: 1)…but he didn't make his most important discovery until after the war. 2)The importance of Fleming's discovery was not fully recognized until World War II. 三、特殊疑问句强调句型的构成: 特殊疑问词+be+it+that+句子的其他部分(用陈述语序) 例如: When did you receive the gift? 对特殊疑问词 when 做强调: When was it that you received the gift? 注意此句中的 received 是由 did 加 receive 结合而成的。 (强调主语) (强调宾语)

(强调时间状语) (强调地点状语)

答案及解析 练习 1 注意:判断句子是否为强调句型可以先把“It be..that”部分去掉,如果去掉后句子仍然成 立,那么这个句子就是强调句型;如果去掉后句子不正确,则不是强调句型。但是被强调部 分是原句的宾语时,去掉“It be…that”部分后宾语要放到谓语的后面才是一个通顺的句子。 如: was an old beggar whom/that Mary met in the street yesterday.去掉 it was…that 后为 an old It

beggar Mary met in the street yesterday。an old beggar 做 met 的宾语,故要放到 met 之后,即: Mary met an old beggar in the street yesterday. 1.A.it 用做主语指一段时间 fouryears,since 的含义为“自从”,引导时间状语从句。注意 不要和强调句型混淆。 2.B.not…until 用于强调句型。 3.B.被强调部分是一个时间状语从句。 4.A.第一空为定语从句的引导词部分,既可以使用 that 又可以使用 which,第二空为强 调句型部分,应用 that,被强调部分为 in the lab. 5.A.第一空为主语从句的引导词部分, 使用 what 做 did 的宾语, 第二空为强调句型部分, 应用 that。 6.B.对特殊疑问词 where 进行强调。 7.C。在强调句型中,如果强调部分是原句的主语,that 后面的谓语动词部分要与主语 保持一致,排除 A、B 两项,D 项中的时态不一致。 练习 2 1.It was Peter who lent us the money. 2.It is money that they want. 3.It was on Monday that all this happened. 4.It was not until last summer that I heard from her. 5.Why is it that everyone thinks I am narrow-minded?
