高考英语专题复习——强调句

强调句强调的类别说   明例   句It is (was) +被强调部分+that(who)…为了强调句子的某一成分（通常是主语、宾语或状语），常用强调结构：It is (was) +被强调部分+that(who)…表示强调的it在这种结构的句子中作主句的主语。原始句：Last night I saw a film in the Youth Palace.强调主语： It was I that (or: who) saw a film in the Youth Palace last night.强调宾语：It was a fiml that I saw in the Youth Palace last night.强调地点状语：It was in the Youth Palace that I saw a film last night.强调时间状语：It was last night that I saw a film in the Youth Palace. 一般讲，原句的谓语动词如果是现在或将来各种时态，用It is…that (who)…；如果原句谓语动词是过去各种时态，则用It was… that(who)…。注意点①在强调主语时，that后的谓语动词要与被强调者保持人称和数的It is I who am a teacher.②即使被强调的主语是复数，主句中的谓语动词也用单数It is they who often help me with my lessons.③在强调时间、地点、原因、或方式状语时，不要用when,where,why或 how ，而用that It was because her mother was ill that she didn't go with us.④在强调not … until 结构中由 until 短语（或从句）表示的时间状语时，要用固定的强调句型It is(was) not until ...that...。that 从句中的谓语动词用肯定式。My father didn't come home until 12 o'clock last night.It was not until 12 o'clock last night that my father came home.⑤在强调一般疑问句中的某一成分时，主句要用一般疑问句的语序：把is/ was提到it前面。Did this happen in Beijing?Was it in Beijing that this happened? ⑥特殊疑问句中只有疑问词可以强调，其强调结构是“被强调部分（通常是疑问代词或疑问副词）+ is/was + it + that/ who + 其它部分?"Where were you born?Where was it that you were born?⑦not …until…句型的强调句句型为：It is/ was not until + 被强调部分 + that + 其它部分原始句：He didn’t go to bed until/ till his wife came back.强调句：It was not until his wife came back that he went to bed.此句型只用until，不用till。但如果不是强调句型，till, until可通用；因为句型中It is/ was not … 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。谓语动词的强调It is/ was … that …结构不能强调谓语，如果需要强调谓语时，用助动词do/ does或did。Do sit down. 务必请坐。He did write to you last week.上周他确实给你写了信。Do be careful when you cross the street.过马路时，务必（千万）要小心啊！此种强调只用do/does和did ，没有别的形式；过去时用did，后面的谓语动词用原形。
