粤教版必修六Unit 4参考课件训练.docx

1、粤教版必修六Unit 4参考课件训练it引领强调句的旗手温故知新 上个单元我们学习了it 用作人称代词、非人称代词，形式主语、形式宾语的用法。今天我们来学习it用在强调结构中的用法。这也是高考的一个热点语法现象，你要用心学哦！句例呈现 请观察下列句子，看看它们与原句“My father did the experiment in the lab yesterday evening.”有何不同，它们又有何共性呢？1. It was my father that / who did the experiment in the lab yesterday evening.2. It was the

2、experiment that my father did in the lab yesterday evening.3. It was yesterday evening that my father did the experiment in the lab.4. It was in the lab that my father did the experiment yesterday evening.功能小结 通过观察这四个句子我们发现：在It was 和that / who之间插入了单词或短语，它们分别是原句的四个成分（主语、宾语、时间状语、地点状语），且这四个句子都是It was .

3、 that结构，我们把它们叫做it强调句型。 it强调句起的是强调句子的某一成分的作用。我们可以用it强调结构强调主语（句1）、宾语（句2）、时间状语（句3）、地点状语（句4）等。换句话说，此结构可以强调除谓语以外的所有句子成分。有些同学会问：句3和句4中的that可以换成when和where吗？当然不可以。只有在强调的部分是某人的时候，that才可以换成who或whom，其他情况只能用that。要点聚焦 观察对比以下句子，看看它们各有什么特殊之处？1. It was at ten oclock that we got home last night2. It was ten oclock w

4、hen we got home last night. 3. Was it at ten oclock that we got home last night?4. When was it that we got home last night?5. I asked you when it was that we got home last night.6. It was not until ten oclock that we got home last night.7. Could it be in the restaurant where you had dinner with me y

5、esterday that you left behind your keys and wallet?画龙点睛 对比句1和句2你会发现it的用法是不同的：句1为强调句，而句2并不是it强调结构，it指代的是时间。 it强调句的一般疑问句形式（句3）、特殊疑问句形式（句4）及it强调结构作宾语（用陈述语序）（句5）。 not until用在it强调结构中：It was / is + not until +时间状语+ that +其他成分（句6）。 it强调结构和定语从句经常结合在一起（句7）。高考实例 从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。1.

It i

8、s clear (obvious，true，possible，certain) that 2. It is important (necessary，right，strange，natural)that 掌握本句型，应该记住所列举的形容词，并且记住that后的从句应用虚拟语气 (should+动词原形)，should可以省去。 3. It is no good (use) doing sth 4. It is a pity (a shame ) that 本句型中，that后的从句一般用虚拟语气 (should十动词原形)，should可以省去。表示出乎意料，常译为“竟然”。没有这种意义时，则

9、不用虚拟语气。 5. It is time (about time，high time) that 本句型中that后的从句应该用虚拟语气。 6. It is the first (second)time that 7. It is said (reported，learned)that 8. It is suggested (ordered) that 本句型中的过去分词应该是表示请求、建议、命令等的词，that后的从句要用虚拟语气(should十动词原形)，should可以省略。常译为“据建议；有命令”。 9. It happens (seems，appears) that 10. It

10、takes sbto do sth 11. It doesnt matter whether 12. It is kind (of sb) to do sth 本句型中的不定式如果需要逻辑主语，则须要前置介词of，而句型中的形容词必须是能表示逻辑主语特征的形容词，常见的有bad，brave，careless，clever，cruel，foolish，honest，horrible，kind，lazy，modest，naughty, polite，rude，silly, stupid，wise，wrong等。 13. It is necessary ( for sb) to do sth 14.

11、 It is (just) like sb to do sth 本句型为“某人(恰恰)是样子”。用来表示赞扬或不满，若用否定式，则表示怀疑。 例：Its like him to leave the work to others 他就是这样的一个人，把工作推给别人。 15. It is up to sb to do sth 本句型表示“谊由某人做”。II强调句型 It is+ 被强调部分+that/who 本句型中被强调部分可以是主语、宾语或状语。强调的主语如果是人，that可以由who换用。III其他句型 1. It issince 本句型主句中用时间作表语，一般用现在时或完成时，since引

12、导的从句常用瞬间动词的一般过去时态。主句如用一般过去时，则从句用过去完成时。 2. It iswhen 本句型中的when引导的是一个时间状语从句，主句中的it指时间，表语由具体的时间充当。 3. It looks (seems) as if 本句型中的as if引导一个状语从句，常译为“看起来好像”。如果与事实不相符合，则用虚拟语气 例1 It looks as if he is ill (真的病了) . 例2 It looks as if he were ill (没有生病) .练习1. _ from Beijing to London! A.
