1、初二英语Chapter Six: Newspaper上海牛津版【本讲教育信息】一、教学内容：Chapter Six: Newspaper二、具体过程：（一）虚拟语气的用法 虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。 用以表示虚拟条件的虚拟语气 用if条件从句表示的虚拟条件，是虚拟条件最普通的方式。 虚拟现在时表示与现在事实相反的假设，其if 从句的谓语形式用动词的过去式(be 一般用were)，主句用would/ should/ could/ might +动词原形，例如：If I were in your position I would
2、 marry her. 虚拟过去时是表示与过去事实相反的假设，if 从句的谓语形式用过去完成时即had过去分词，主句用would / should / could / might + have +过去分词，例如：If it had not rained so hard yesterday we could have played tennis. 大多数的虚拟条件句属于上面三种情况中的一种，但并不排除存在于条件和结果中，一个和现在情况相反，另一个和过去情况相反，例如：If you had followed what the doctor said, you would not have been
3、 so painful now. 这个句子在高中出现频率颇高。 但是，如果结果用了虚拟语气，而条件却用陈述语气，这种用法是错误的。1) 虚拟语气用在简单句中，表示祝愿，命令。 May you be happy. 祝你幸福。 May you have a good time. 祝愿你玩得痛快。 May the friendship between us last long. 祝愿我们的友情天长地久。 Have a good journey! 祝愿你旅途愉快！ You go out！ 你出去！ 2) 虚拟语气用在宾语从句中。动词 wish, suggest, order, insist, prop
4、ose 等词后面的宾语从句表示的是一种虚拟语气， 宾语从句中的动词动作表示的只是一种愿望，要求。 I wish she would be on my side. 我希望她能站在我这一边。 I wish I could help him. 我希望我能帮助他。 He insisted that all of us should be there on time by any means. 他坚持要我们大家想尽办法按时去那儿。 动词 demand, suggest, order, insist, propose 后面的从句中，“should” 可以省略。 The teacher suggested
5、that we (should) clean the blackboard after class. 老师建议我们课后把黑板擦了。 He ordered that the students wash the clothes every week by themselves. 他要求学生每周都要自己洗衣服。 3) 虚拟语气用在主语从句中。 在句型 “It is important (necessary, strange, natural) that . . . . ” 中，that 后面的从句中的谓语动词用： should + 动词原形 Its necessary that we should
6、have a walk now. 我们有必要出去散散步。 Its natural that she should do so. 她这样做是很自然的。 Its important that we should take good care of the patient. 重要的是我们要照顾好病人。 4) 虚拟语气用在状语从句中。 虚拟语气多用于表示条件的状语从句和表示结果的主句中。在表示与事实相反的虚拟语气时，动词有三种时态形式，即现在，过去和将来。 与现在事实相反的： 条件从句 结果从句 If I (we, you, he, they)+ 动词过去式, If I (he, she) were.
7、 . . I (we) should + 动词原形。 He (you, they) would + 动词原形。 与过去事实相反的： 条件从句 结果从句 If I(we, you, he, they)+ had + 过去分词 I(we)should + have+ 过去分词。He (you, they) would + have + 过去分词。 If I were you, I should buy it. 如果我是你，我就买了它。 If I had time, I would study French. 如果我有时间，我会学习法语的。 If she knew English, she woul
8、d not ask me for help. 如果她懂英语的话，她不会找我帮忙的。 If you had got up earlier, you could have caught the train. 如果你早一点起床，就会赶上火车的。 If it were fine tomorrow, I would go shopping. 如果明天天气好，我就去买东西。 有关虚拟语气的几个问题： 1) 有时if引导的状语从句可以省略 if，而把从句中的动词 were, had 或 should 移到主语前面。 Were she younger, she would do it. 如果她年轻点， 她就会
9、干的。 Had he known her address, he would had gone to visit her. 如果他知道她的地址，他会去看她的。 2) 有时表示虚拟语气的条件从句或者主句都可以省略，而只剩下一个主句或者一个条件从句。 I could help you. 我本来可以帮助你。 If I had time. 我要有时间该多好啊。 She should have come to the party. 她应该来参加聚会。 If he had much more money. 如果他有更多的钱。 3) 虚拟语气中，条件从句的动词动作可以和主句的动词动作时态不一致。 If th
10、ey had studied hard, they could do it easily now. 如果他们以前努力学习的话，现在干的就会容易些。 If he had not taken my advice, he wouldnt do it much better like this. 如果他不听取我的建议，他就不会干得这样好。（二）状语从句由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。高考中已考查了时间、让步、地点、条件、目
11、的等状语从句，这些从句仍是今后高考的热点，应作充分准备。同时对方式状语从句也应引起重视。1. 时间状语从句表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner than, hardly (scarcely) when, every time等引导。e. g. : When I came into the office, the teachers were having a meeting.
12、He started as soon as he received the news. Once you see him, you will never forget him. No sooner had I gone to bed than I went to sleep. 2. 原因状语从句原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。e. g. He is disappointed because he didnt get t
13、he position. As it is raining, I will not go out. Now that you mention it, I do remember. 3. 地点状语从句引导地点状语从句的连词是where 和wherever等。e. g. Sit wherever you like. Make a mark where you have a question. 4. 目的状语从句引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。e. g. Speak clearly, s
14、o that they may understand you. She has bought the book in order that she could follow the TV lessons. He left early in case he should miss the train. 5. 结果状语从句结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that （从句谓语一般没有情态动词）, so that, such that等引导。 e. g. She was ill, so that she didnt attend the meeting. He w
15、as so excited that he could not say a word. She is such a good teacher that everyone admires her. 6. 条件状语从句条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。注意：条件从句中的if 不能用whether替换。e. g. If he is not in the office, he must be out for lunch. You may borrow the book so long as you keep it clean. So far as I know（据我所知）, he will be away for three months. You can go swimming on condition that ( = if ) you dont go too far away from the river bank. If he had come a few minutes
