2017届高考英语牛津版一轮复习语法考点专练课件：10 特殊句式

　　强调人时可用 who/that来连接,强调事物时常用 that。所强调的可以是单词、短语,也可以是从句,但结构必须完整。被强调的成分可以是主语、宾语或状语,但不能是定语或谓语。如: It is I who/that am right. 我才是对的。(主语) It was him that/who we met at the school gate. 我们在校门口见到的就是他。(宾语) It was in the park that Tom lost his watch. 汤姆是在公园里丢的那只手表。(状语) 2.强调句型的一般疑问句形式:Is/Was it+被强调部分+that/who+其他成分?如: Was it in 1939 that the Second World War broke out?

　　第二次世界大战是在1939年爆发的吗? Is it Professor Wang who teaches you English? 教你们英语的是王教授吗? 3.强调句型的特殊疑问句形式:特殊疑问词+is/was+it+that+其他成分?如: Who was it that broke the window?打破窗户的是谁? When was it that you called me yesterday? 你昨天给我打电话是什么时候? What is it that you want me to do? 你要我干什么? 4.有时可用It might be...that...,It must have been...that...句型表示强调。如: It might be his father that you're looking for. 你正在找的可能是他父亲。 It must have been his brother that you saw. 你看到的一定是他的弟弟。 5.not...until...句型的强调句其强调句式为:It is/was not until...+that+其他成分。如: He didn't go to bed until ten o'clock. →It was not until ten o'clock that he went to bed. 直到10点他才上床睡觉。 I didn't realize she was a famous film star until she took off her dark glasses. →It was not until she took off her dark glasses that I realized she was a famous film star. 直到她摘掉墨镜我才认出她是一位著名影星。 6.强调句型中的it与作形式主语的it 可根据能否恢复原句来判断,即把It is/was和that去掉,如果剩下的成分仍然能构成一个完整的句子,这就是强调句型,否则就不是。如: It is there that accidents often happen. →Accidents often happen there. 事故经常在那里发生。以上就是强调句型,被强调成分是状语,把It is和that去掉,可还原成原来的非强调句。 It is clear that not all boys like football. 很显然并非所有男孩都喜欢足球。去掉 It is和that,句子成了:Clear not all boys like football. 很显然这不是一个完整的句子,因此不是强调句型,而是由it 作形式主语,that从句作真正主语的复合句。 7.强调句型 It is/was...that...;It is/was+时间+when/before从句;It is+时间+since 从句;It was not long...before...等句型的区别 (1)强调句型与It is/was+时间+when/before 从句在“It is/was+时间+when/before从句”中,it 指时间,when/before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。如: It was at midnight that I got back home yesterday. 昨天午夜我回到了家里。 It was midnight when/before I got back home yesterday. 昨天当我回到家里时,已经是午夜了。/昨天我还没到家就到了午夜了。第一句是强调句型,被强调的是时间状语,因此用介词短语表达;而第二句是一般句型,时间以名词的方式表达,用来作表语。 (2)强调句型与 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: It was two years ago that I began to learn English. 我是在两年前开始学英语的。 It is two years since I began to learn English. 我学英语两年了。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时间”,主句用一般现在时,其强调句型同样可以用一般现在时。如: It is two hours that he spends on English every day. 他每天花在学英语上的时间是两个小时。 (3)强调句型与It was not long...before... 上述句型可有以下几个句式: It wasn't long before...不久以后就……了 It won't be long before...不久就会…… It was two years/days before... 过了两年/两天才…… It was not two years/days before... 不到两年/两天就…… It will be two years/days before...还得两年/两天才…… It will not be two years/days before... 用不了两年/两天就会…… 试比较: It was two years before he came back from abroad. It was two years later that he came back from abroad. 同样表示“他两年以后回国”,强调句型中应注意状语的表达方式。二、对谓语动词的强调 It is/was...that...结构不能强调谓语动词。如果需要强调谓语动词,用助动词do, did 或does。如: Do come this evening. 今天晚上一定要来呀。 He did write to you last week. 上周他的确给你写信了。 Tom does study hard now. 现在汤姆的确学习很努力。
