高二英语 Unit 2 Grammar 虚拟语气 II 人教新课标版选修 6一、学习目标:1. 学习虚拟语气在名词性从句中及其他从句中的应用。
2. 掌握虚拟语气使用的语境及方法。
二、重点、难点:虚拟语气在各种从句中的句型结构。
三、考情分析:在高考题中,目前全国19套各省试题中涉及到虚拟语气知识点的占30%以上,因此这一语法项目在高考中变得越来越重要。
这一知识点经常以单项选择题的形式出现,分值为1分。
而且,我们在日常对话中也经常会用到虚拟语气。
四、知能提升(一)知识讲解【认知讲解】l. 虚拟语气在主语从句中的用法:1)在“It is important (strange,natural,necessary)that…”这类句型里,that所引导的主语从句中的谓语动词常用“should+动词原形”结构,表示某事是“重要”、“奇怪”、“自然”、“必要”的等意义。
It is important that every member (should) inform himself of these rules.重要的是每个成员都应该知道这些规则。
It is necessary that we (should) do something to protect the environment.我们每一个人都很有必要做些事情来保护环境。
It is strange that a well behaved gentleman should be so rude to the lady.真奇怪,那个举止得体的绅士竟然对那位女士如此粗鲁。
2)It is ordered/suggested that…从句that引导的主语从句的谓语动词用“(should)+v.”结构。
这一类的动词还有:propose, require, demand, request, insist, ask等。
It is ordered that the cloth (should) be woven right now.命令传来,应该马上织布。
Section Ⅲ Grammar——虚拟语气(Ⅱ)一、错综时间条件句(混合条件句)当条件状语从句表示的动作或行为和主句表示的动作或行为所发生的时间不一致时,被称为“错综时间条件句”,动词的形式要根据它所表示的时间作出相应的调整。
If you had followed my advice just now,you would be better now.如果你刚才听了我的建议,你现在就好多了。
If he were free today,we would have sent him to Beijing.如果他今天有空的话,我们就派他去北京了。
[即时训练1] 用所给词的适当形式填空①If you had studied (study)hard before,you would be (be)a college student now.②If you hadn't lost the map,we would be (be)back in the hotel now.二、含蓄虚拟条件句有时虚拟的条件不通过条件从句表达出来,而是暗含在单词、短语或上下文中,这时需要根据句中所表述的意义以及某些特定的信息词来判断此时需要采用的形式。
常用词或短语有:with,without,but for,or else,or,otherwise等。
But for her help,they couldn't have run over the mountain in such a short time.要不是她的帮助,他们不会在那么短的时间内翻过那座山。
I was ill that day.Otherwise,I would have taken part in the sports meeting.我那天病了。
否则,我就参加运动会了。
He must have been there,or he never could know the place so well.他一定去过那儿,否则他决不会如此了解那个地方。
虚拟语气(2)编稿:牛新阁审稿:王春霞概念引入上一单元我们学习了虚拟语气中与现在、将来事实相反的虚拟条件句及宾语从句的虚拟语气。
本单元要继续学习虚拟语气中与过去事实相反的虚拟条件句,及虚拟语气在其它从句中的应用。
首先,我们先看下面含虚拟语气的句子:1. We would have won, if Jack had scored that goal.2. We would have won if we hadn’t stayed up so late the night before.3. We would have won the championship, if we had got Mr Han to coach us.4. If she had studied harder, she would have got the diploma.这些句子都是与过去事实相反的虚拟条件句。
下面我们就来学习这部分内容。
用法讲解与过去事实相反的虚拟条件句虚拟条件句的动词形式从表格可知,虚拟条件句与过去事实相反时,条件从句的谓语用过去完成时,而主句的谓语用would/should/might/could加现在完成时形式。
If he had taken my advice, he would not have made such a mistake.如果他听我的劝告的话,就不会犯这样的错误了。
(事实:没有听我的话---he didn’t take my advice)If you had e a few minutes earlier,you would have met him.要是你早来几分钟的话,你就见到他了。
(事实:来晚了---you came late)If She hadn’t been so strict with herself, she wouldn’t have made such great progress.她要是对自己要求不严格,她就不会有这样大的进步。
