初中英语强调句型的用法及注意事项

发布时间：2013-07-18 编辑：查字典英语网小编

　　【小编编语】今天查字典英语网小编教给同学们的是初中英语强调句型的用法及注意事项，一起来学习下吧!

　　一、强调句型的用法：

　　在英语中，我们常用It is/was… 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。例如：It is my mother who/that cooks every day. It was yesterday that Tom passed in the maths exam

　　二、使用本句型的几个注意事项：

　　1.被强调成分是主语，who/that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。例如：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，要用 that。例如：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.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。例如：It was he that helped me yesterday. It was me that he helped yesterday.

　　4.被强调部分既包括人又包括物，用that不用who。例如：lt was the things and people that they remembered that they were talking about.

　　三、强调句例句：

　　针对“I met Li Ming at the railway station yesterday.句子进行强调。

　　强调主语：It was I that (who) met Li Ming at the railway station yesterday.

　　强调宾语：It was Li Ming that I met at the railway station yesterday.

　　强调地点状语：It was at the railway station that I met Li Ming yesterday.

　　强调时间状语：It was yesterday that I met Li Ming at the railway station

　　四、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。例如：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!

　　注意：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。
