1、强调句型用法及注意事项,一、强调句型的用法 在英语中，我们常用It iswas who/that结构来突出强调句子的某一成分(一般是句子中主语，宾语或状语)。在这个句型中，it没有词汇意义，只是引出被强调的成分。如果被强调的成分是表示人的词，用who或that来连接都可以。如果是其它成分，则一律用that来连接。 It was in the park that I met my old teacher yesterday.(强调地点状语) It was yesterday that I met my old teacher in the park.(强调时间状语) It was my old
2、teacher that I met in the park yesterday.(强调宾语) It is Mr Smith who/that thinks Tom is a clever boy.(强调主语),二、使用本句型的几个注意事项 1被强调成分是主语，whothat之后的谓语动词应该在人称和数上与原句中的主语保持一致。 E.g. It is I who am right It is he who is wrong It is the students who are lovely 2即使被强调成分是句子中的时间状语，地点状语，原因状语等，也不能用when，where, because
3、，要用 that。 E.g. It was after the war was over that Einstein was able to come back to his research work again.,It was in front of the bank that the old lady was robbed It was because of the heavy rain that he came late,3如果被强调的成分有同位语，同位语也应提前。 It was from him，his chemistry teacher that Paul learned to w
4、atch carefully in class 4被强调成分是作主语的代词，用主格，是作宾语的代词，用宾格 It was he that helped me yesterday. It was me that he helped yesterday,5被强调部分既包括人又包括物，用that不用who lt was the things and people that they remembered that they were talking about 6.在强调结构中,无论被强调的是人还是物,是单数还是复数,be动词一律用is/was形式,如果原句的谓语动词是一般过去时,就用was;如果是
5、一般现在时,就用is.也可以用“情态动词+be“形式.如: It is the monitor who wins the first prize in the exam. It was the farmers who/that lived a hard life be fore liberation. It might be yesterday that John bought a book for Mary. It will be Xiao Wang who go with you.,三、区分定语从句和强调句型某些定语从句和强调句型形式差不多，容易混淆。如果去掉it is was .that
6、句子仍然通顺成立，则为强调句型，不成立不通顺，则为定语从句。 E.g. It was three years ago that he went to American for a further study去掉It was that句子为Three years ago he went to America for a further study句子通顺，意思完整，那么，这就是一个强调句型。,四、强调句型也有疑问句形式.一般疑问句的强调形式,只需将is/was提前,移至句首即可,即:“Is/Was itthat“.特殊疑问句的强调形式,须将陈述句变成一般疑问句,再在句首加上疑问词,即“疑问词(被
7、强调部分)+is/was + it + that + 句子其余部分“.如:1 X; s$ _$ T* R J: e Was it last year that the building was completed How was it that he went to school 哲理性,故常用一般现在时.例如: Its a wise father who knows his own child.无论多聪明的父亲也不见得了解自己的孩子,四、强调句型也有疑问句形式.一般疑问句的强调形式,只需将is/was提前,移至句首即可,即:“Is/Was itthat“.特殊疑问句的强调形式,须将陈述句变成一般疑问句,再在句首加上疑问词,即“疑问词(被强调部分)+is/was + it + that + 句子其余部分“.如:1 X; s$ _$ T* R J: e Was it last year that the building was completed How was it that he went to school 哲理性,故常用一般现在时.例如: Its a wise father who knows his own child.无论多聪明的父亲也不见得了解自己的孩子,The end,谢谢 本次课程到此结束,
