Unit 4 Global warming Grammar 课件(人教选修6)
答案： B
4．(2010· 安徽高考)It was from only a few supplies
that she had bought in the village ________ the hostess cooked such a nice dinner. A．where C．when B．that D．which
解析：考查强调句型It is/was ... that ...。句意： 直到来到此地我才意识到该地不仅风景秀丽
而且气候宜人。对含有not until的句型进行
强调时，应该用It is/was not until ...that ...。 答案：B
2．(2011· 湖南高考)It's not what we do once
用介词短语表达，而第二句是一般句型，时间以
名词的方式表达，用来作表语。
3．强调结构与It＋was/will be＋一段时间＋before 从句该句型中的时间常为long, a long time, years, months, weeks, days, hours, minutes等时间段。 It was two years before he came back from abroad. 过了两年他才从国外回来。 It was two years later that he came back from
①It was at the railway station that we first met 10 years ago. ②It was the railway station where we first met 10 years ago.
三、与强调句型容易混淆的句型
1．强调结构与It is＋时间＋since从句 It is ... since ...表示“自从……以来已有……(时 间)”。注意：两个句型中的时态一般不同，试比 较：
3．not ... until ...句型的强调句式 It is/was not until＋被强调部分＋that＋其他成 分。 It was not until Dr. Weeks came to China that she knew what kind of a country she is. 直到威克斯博士来到中国后，她才认识到中国
[课堂高考小试]
1. (2012· 湖南高考)It was not until I came here
________ I realized this place was famous for not only its beauty but also its weather. A．who C．where B．that D．before
[生活中的语法]
[观察后的发现]
1．It is human activity that has caused this global warming. 2．It is enviromentalists that/who have tried to stop the earth's temperature rising. 3．Was it during the 20th century that the temperature of the earth went up about one degree Fahrenheit? 4．When was it that he moved to America? 5．It must be Jack who/that let out the secret. 6．It was not until she took off her glasses that we recognised her.
时间”，用一般现在时或现在完成时。
2．强调结构与It is/was＋时间＋when从句
It is/was ...when ...中it指时间，when引导的是时 间状语从句。注意两种句型“时间”表达方式的 不同。试比较：
It was at midnight that I got back home yesterday. 昨天午夜我回到了家里。 It was midnight when I got back home yesterday. 当我昨天回到家里时，已经是午夜了。 第一句是强调句型，被强调的是时间状语，因此
＋其他成分”句型。
It was me that he helped yesterday.
他昨天帮的人是我。
It was because of the heavy rain that he came late.
由于下ห้องสมุดไป่ตู้雨他来晚了。
It is he who/that often helps me with my English.
是一个什么样的国家。
[点津] 有时可用It might be ... that/who ...或It
must be ... that/who ...句型表示强调。
It might be his father that he are worried about. 他担心的可能是他父亲。 It must be he that cleaned the classroom. 一定是他打扫了教室。
是他经常帮我学英语。
2．强调句型的一般疑问句式和特殊疑问句式
(1)一般疑问句式：Is/Was it＋被强调部分＋ that/who ＋其他成分？ Was it during the Second World War that he died? 他是二战期间死亡的吗？
(2)特殊疑问句式：特殊疑问词＋is/was it＋ that/who＋其他 成分？ Where was it that you lost your car? 你是在哪儿丢的车？ Why is it that you put off the meeting? 你为什么推迟会议呢？
13.句型转换 The little boy didn't go to bed until his mother came back. → It not was until his little boy went to bed. mother came backthat the
二、强调句型与其他从句的辨析 在判定是强调句型还是从句时，如果原句去 掉it is/was和that/who后仍然是一个完整句子则为 强调句型，反之则为其他从句。 It is clear that not all boys like football. 很明显不是所有的男孩都喜欢踢足球。 (主语从句) It was such a hot day that even the crops withered. 天气极度炎热，连庄稼都枯萎了。 (结果状语从句)
It was two years ago that I began to learn English. 我是两年前开始学英语的。 It is/has been two years since I began to learn English. 自从我开始学英语到现在有两年了。 第一句为强调句型，强调的是过去的事情，用一 般过去时，而第二句表示“从过去到现在已有多长
③ It was in the street that I met him yesterday. ④ It was yesterday that I met him in the street.
12.完成句子 ①教你们英语的是王教授吗？ Is it Professor Wang that/who teaches you English? ②他究竟从哪里得到的信息？ Where was it that he got the information?
11.通过强调划线部分将下面句子改为强调句型 I met him in the street yesterday． ① It was I that/who met him in the street yesterday. ② It was him that/who I met in the street yesterday.
abroad.两年之后他才从国外回来。
第一句为状语从句，it表示时间。第二句为强调
句型，强调的是时间状语two years later。
①It has been three years since I stayed in Beijing.
②It will be three days before he makes a decision. ③It will be midnight when he comes back. ④It was at 5 o'clock that he set off in the morning.
that/who＋其他成分？(如例句4) (4)强调句型中的is/was有时可用“ 情态动词 ＋be”代替。(如 例句5) (5)not until的强调句型为：It is/was＋not until ...＋that ＋其他成分 。(如例句6)
一、it用于强调句型 1．强调句型的基本结构 要强调一个句子中除谓语以外的句子成 分(如主语、宾语、表语、状语等)，可以 使用“It is/was＋被强调部分＋that/who
解析：考查强调句式。被强调部分是from only a few supplies；句中的“that she had bought in the village”是定语从句，修饰先行词supplies；句子主 干为the hostess cooked such a nice dinner。故选B 项。 答案：B
in a while ________ shapes our lives, but what we do consistently.
A．which
C．how
B．that
D．when
解析：考查强调句型。此句强调句子的
