Question

John’s success has nothing to do with good luck. It is years of hard work ________ has made him what he is today.

A. whyB. thatC. whenD. which

Answer

B

【解析】

试题分析：考查强调句型。句意：约翰的成功与好运气没有任何关系，是几年的辛苦工作使得他成为今天的样子。因为这是一个强调句，强调句的固定句型是It is ...+that从句，要判断一个句子是强调句，只要看它去掉了It is和that后句子能否仍然成立。若成立，则是强调句。故选B。

【名师点睛】

一、强调句句型：

1、用It is／was...that／who...句型表示强调。

（1）陈述句的强调句型：It is/was+被强调部分（通常是主语、宾语或状语）+that/who（当强调主语且主语指人）+其它部分。 e.g. It was yesterday that he met Li Ping.

（2）一般疑问句的强调句型：同上，只是把is/was提到it前面。 e.g. Was it yesterday that he met Li Ping?

（3）特殊疑问句的强调句型：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？ e.g. When and where was it that you were born?

注：被强调的部分（通常是句子的主语、状语、宾语或宾语补足语）放在is／was的后面，如被强调的是人，则后面可用who，whom等代替。如：原句：He met an old friend in the park yesterday. 强调主语：It was he who/that met an old friend in the park yesterday.

2、用助动词do, does或did来强调谓语动词。

如：Do come early. He did send you a letter last week.

3、用主语从句+be+被强调部分，主语从句常用what引导。

如：What John wants is a ball.What Mary does every day is(to) give piano lessons.

二、not...until...句型的强调句：

1、句型为：It is/was not until+被强调部分+that+其它部分：

e.g. 普通句：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.

2、注意：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。三、谓语动词的强调：

1、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。

e.g. Do sit down.务必请坐。

He did write to you last week. 上周他确实给你写了信。

2、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。
