高二英语Unit 1 Grammar 虚拟语气知识精讲新人教版选修6一、学习目标：1. 学习虚拟语气在条件句中的应用。
2. 掌握虚拟语气使用的语境与方法。
二、重点、难点：虚拟语气在条件句中的句型结构。
三、考情分析：在高考题中，目前全国19套各地市试题中涉与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会经常用到虚拟语气。
四、知能提升〔一〕知识讲解【认知讲解】教材原句呈现①If you were an artist, what kind of pictures would you paint?②If the rules of perspective had not been discovered, no one would have been able to paint such realistic pictures.③Have you ever wished you could paint as well as a professional artist?比照分析第一个句子中的从句显然是做了一个不可能成立的假设，这是一个与现在事实相反的虚拟语气的句子。
第二个句子中如此是与过去事实相反，是表示如果透视法没有被发现，就没有人能够画出这样具有现实主义的画来。
第三个句子中wish后面的虚拟语气，表示与将来事实相反。
【重、难点】1〕虚拟语气可以用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。
虚拟语气在条件句中应用得比拟多。
2〕条件句可分为两类，一类为真实条件句，一类为非真实条件句。
非真实条件句表示的是假设的或实际发生的可能性不大的情况，故采用虚拟语气。
I.真实条件句用于陈述语气，所假设的情况有可能发生。
结构如下所示：从句往往用一般现在时，而主句如此由“shall/will + 动词原形〞构成。

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。
【考题链接】（1）It is required that you ____ at six.A. will arriveB. arriveC. arrivedD. would arrive答案：B解题思路：在“It is required that…”句型中，that引导的主语从句要用虚拟语气，谓语动词用“should +v”，这里省略了should，所以选B项。
（2）It is important that I ___ with Mr. Williams immediately.A. speakB. spokeC. will speakD. to speak答案：A解题思路：在“It is important that…”句型中，that引导的主语从句要用虚拟语气，谓语动词用“should+ v”，在这里省略了should，所以选A项。
（3）It is really strange that the girl _______ so early.A. has been marriedB. has marriedC. should have been marriedD. would marry答案：C解题思路：在“It is strange that…”句型中，that引导的主语从句要用虚拟语气，谓语动词用“should +v”，在这里叙述的是过去的事情，所以用到了完成式。
2. 虚拟语气在宾语从句中的用法：(1)在动词wish后的宾语从句中。
（13讲已经讲解，不再重复）(2)在suggest，demand，order，propose，insist，command，request，desire表示建议、要求、命令等动词后的宾语从句中，谓语动词用“should + 动词原形”结构，我们可以用一个口诀来记忆：一坚持（insist）二命令（order，command）三建议（advise，suggest，propose）四要求（ask，demand，require，request）。
Her father insists that she (should) learn music after she leaves school.她父亲坚持她毕业后学习音乐。
The doctor recommended that I take more exercise to lose weight.医生建议我要多运动以减轻体重。
Our teacher required that we should finish our homework before supper.老师要求我们晚饭前把作业做完。
I demand that he (should) answer me immediately. 我要求他立刻答复我。
【易错点】在这些动词里面，insist和suggest较为特殊，suggest表示“表明，暗示”时，insist表示“坚持”一个事实时，后面不用虚拟语气。
Alice insisted that she had done nothing wrong and that she shouldn’t be blamed.爱丽丝坚持说她没做错什么，不应该受到责备。
The smile on his face suggested that he had passed the exam.他脸上的微笑表明他通过了考试。
【考题链接】(1) He insisted that John ________ it.A. doB. doesC. didD. would do答案：A解题思路：考查insist后面的虚拟语气。
结构为should+动词原形，should可以省略。
(2) Mr. Smith insisted that he ________ nothing wrong and that he_______.A. had done; be freedB. have done; should be freedC. did; freedD. do; be freed答案：A解题思路：第一个空白处是坚持一个事实，不用虚拟语气，而第二个空白处则用虚拟语气，所以A项正确。
(3) His tired face suggested that he ________ really tired after the long walk.A. had beenB. wasC. beD. should be答案：B解题思路：这里的suggest意为表明，后面不接虚拟语气。
(4) Teachers recommend parents their children under 12 to ride bicycles to school for safety.A. not allowB. do not allowC. mu stn’t allowD. couldn’t allow答案：A解题思路：recommend 后面的（that）从句中要用虚拟语气，谓语动词用“should+ do”, should可以省略。
Teachers recommend parents should not allow…=Teachers recommend parents not allow…句意：老师建议父母出于安全考虑最好不要让12岁以下的孩子骑自行车去学校。
3. 虚拟语气在其他名词性从句中的应用：1）表语从句：虚拟语气还可用于某些表语从句中，谓语动词用(should)+v结构。
常有下列名词作主语：order, suggestion, request, proposal, advice, requirement, plan, idea, decision.His order is that we(should) set out right now.他的命令是我们立刻出发。
【考题链接】（1）The doctor’s advice is that the patient ______ about his real p hysical condition.A. be not toldB. not be toldC. will not be toldD. must not be told答案：B解题思路：由advice作主语的表语从句用虚拟语气，谓语动词用“should (not) +v”，在这里省略了should，故选B项。
2）The idea is that the nation ______ an unmanned spacecraft to explore the planet first.A. sentB. sendsC. sendD. must send答案：C解题思路：同上一小题。
2）虚拟语气还可用于某些同位语从句中，常用单词有order, suggestion, request, proposal, advice, requirement, plan, idea, decision；同位语从句中的谓语动词用(should)+v形式。
What do you think of his proposal that we should put on a play at the English Evening?你认为他的关于我们应该在英语晚会上进行演出的建议怎样？【考题链接】What do you think of his proposal that improvements ______ in the old type of vacuum cleaner?A. be madeB. will be madeC. would be madeD. will have to be made答案：A解题思路：proposal后的同位语从句要用虚拟语气，谓语动词用“should +v”，should 可以省略，故选A项。
4. 虚拟语气在状语从句中的用法：(1)在带有even if/ even though引导的让步状语从句的主从复合句中，主句和从句都用虚拟语气，动词形式与含有非真实条件句的虚拟语气相同。
Even if he had been ill, he would have gone to his office. 即使生了病，他仍去了办公室。
【考题链接】1）I wouldn’t marry Pa t even if she ______ the last woman on earth.A. isB. wasC. had beenD. were答案：D解题思路：even if引导的让步状语从句要用虚拟语气，本句中是与现在事实相反的虚拟语气，故选D项。
