英语it强调句型怎么用？

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.(强调主语)It was an old beggar whom/that Mary met in the street yesterday.(强调宾语)It was yesterday that Mary met an old beggar in the street.(强调时间状语)It was in the street that Mary met an old beggar yesterday.(强调地点状语)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。

强调句型的构成是：It is (was) + 被强调部分+ that (who) + 句子的其他成分。被强调的部分放在 It is (was) 之后，其它部分置于that之后。被强调部分可以是主语，宾语，表语或状语。强调的主语如果是人，可以由who代替that。 1. 被强调的成分举例：原句：Tom found my pen in the classroom yesterday.强调主语：It was Tom who / that found my pen in the classroom yesterday.强调宾语：It was my pen that Tom found in the classroom yesterday.强调地点状语：It was in the classroom that Tom found my pen yesterday.强调时间状语：It was yesterday that Tom found my pen in the classroom.2. 强调句型的一般疑问式：直接把is或was提到it之前即可。例如：Was it Tom that found your pen in the classroom yesterday?3. 强调句型的特殊疑问式：特殊疑问词+ is (was) it + that +句子的其他成分。特殊疑问词即是被强调的成分。例如：Who was it that found your pen in the classroom yesterday?4. that (who) 有时可以省略：这种强调句型中的that或who有时可以省略。例如：It was my brother (that / whom) you saw the other day.5. 强调原因状语从句要注意：若从句由as或since引导，强调时则改为because，这是因为，because引导的原因从句表示的意义非常强烈，符合强调句的目的。例如：As she got up late, she missed the first bus. 变为：It was because she got up late that she missed the bus.6. 强调句的否定转移：有些否定句在变成强调句时，要把否定转移到被强调的词语之前。尤其是“not... until...”句式的强调要特别注意。例如：He didn't realize his mistake until the teacher had told him. 变为：It wasn't until the teacher had told him that he realized his mistake.【注意】 在强调句式中，虽然not被提前，但“not... until...”句型不要倒装。

小提示：本页面带有字典插件考点一：强调句型的基本结构
强调句型“It is / was + 被强调的成份 + that + 其他成份”用来强调主语、宾语和状语等成份。that只起连接作用，不作成份，但不能省略。有时强调的部分比较特殊，如主语从句、状语从句、名词、不定式短语、V-ing的复合结构等。如：It was in the library that I saw her yesterday. 我昨天正是在图书馆见到她的。考点二：特殊句式中的强调句型1. 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 + 该句的其余部分”。如：How is it that you usually go to work? 你通常是怎样去上班的？2. 在强调“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。如：His father didn't come back from work until 12o'clock. = It was not until 12 o'clock that his father came home form work. 直到12点他的爸爸才下班回家。考点三：强调句型与时间状语从句、定语从句的判断强调句型要注意和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。试比较：It was on March 1 that I had my hair cut. (强调句)It was March 1 when I had my hair cut. (后面是定语从句)判断是否是强调句，可采用“还原法”。如果还原为一般句式后，句子各种成份完整，则是强调句。否则不是。如第一句可还原成：I had my hair cut on March 1.

注意：1.is /was 由句子的时间来定，如果动作发生在过去，用was,如果动作发生在现在或以后用is;2.强调部分不能是谓语动词，形容词；强调部分必须是主语·宾语（如果有修饰语，如：形容词·介词短语·定语从句等一定要和主语·宾语放在一起强调）介词短语或表时间地点的副词做的表语，以及状语。Eg The girl who is dress in a blue skirt sang an sweet English song in the concert hall.1.-----It was the girl who is dress in a blue skirt that(who) sang an sweet English song in the concert hall.2.-----It was an sweet English song that the girl who is dress in a blue skirt sang in the concert hall.3.-----It was in the concert hall that the girl who is dress in a blue skirt sang an sweet English song

It引导的强调句的结构：It is/was+被强调的部分+that/who+其它部分It引导的强调句注意事项：1.无论被强调部分是单数还是复数，It不能用其他代词来代替2.无论被强调部分是单数还是复数，只能用be动词"is或was"3.除了，被强调部分指人，可以用who或that外；其他情况下，无论被强调部分是指时间，地点，原因或其他，只能用that
