人教版 高一Unit 2 English around the world要点讲解
第二单元English around the world
重点句型：
1）While
一、while意为\"当......时候\",指一段时间,不能用来表示一个时间点。
Someone knocked at the door while I was cooking.
While the discussion was still going on, George came in. 当讨论还在进行时,乔治走了进来。
二、while意为\"而;然而\",表示转折。可以用作并列连词，表示对比意义，译为“而”，“却”。
Jane was dresd in blue, while Mary dresd in red. 珍妮穿蓝色衣服，而玛丽却穿红色衣服。
三、while意为\"虽然;尽管\",表示让步。=although
While I admit his good points, I can e his shortcomings. 尽管我承认他的优点,但我还是能看到他的缺点。
四、while意为\"只要\",表示条件。
We can surely overcome the difficulties while we are cloly united. 只要我们紧密地团结一致,一定能克服这些困难。
五、while从句中的省略。
当while从句中的主语与主句的主语一致,且含有be的某种形式时,从句中的主语连同be可同时省略。
While listening to the radio, she fell asleep. 她在听收音机时睡着了。
While in London, he studied music and painting. 在伦敦时,他学习音乐和绘画。
While on his way here,在来这里的途中
He never dreams while asleep.他睡觉时总来不做梦。
六、while还可以用作从属连词，作“在……期间”，“当……时候”讲，使用时应注意它与用作从属连词的when的区别：
when引导的时间状语从句，即可表示“一段时间”，又可表示“一点时间”，因此从句的谓语动词既可以是延续性的，也可以是非延续性的。如：
①I hope to e you when(while)I stay in Beijing on business. (一段时间)当我出差北京时，希望见到你。
②When the clock struck twelve, all the lights went out. (一点时间)当钟敲响十二下时，灯全部熄灭了。
【注意】while引导的时间状语从句只能表示“一段时间”所以 while从句的谓语动词应是延续性动词(或状态动词)。例如：
勤奋图片①While I stayed(or was) in Shanghai, I saw her three times. 我在上海期间见到她三次。关于孝的名言
如果从句的谓语动词是延续性的，可以用while也可以用when。例如：
②While(When) we were having a meeting, a stranger came in. 我们在开会时，一个陌生人走了进来。

作名词用时,主要用于短语中:

2）What is it that Joe can’t find in the bathroom?
用It is／was…that／who…句型表示强调。
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。例如：
He met an old friend in the park yesterday. 他昨天在公园碰见一个老朋友。猫猫图片

It was in the park that he met an old friend yesterday. (强调地点状语)
