中考英语语法复习课件——虚拟语气.ppt

1、，高级中学入学考试英语语法复习精品课件，-家庭法，家庭法：一，概念：家庭法用于表达说话者的主观愿望或虚拟，条件不一定是事实或与事实相反。第二，在条件语句中的应用：条件语句可以分为两个茄子类别。一个是实际的条件语句，一个是不现实的条件语句。不切实际的条件语句表示假设或实际可能性不大的情况，所以使用虚拟语气。1，实际条件语句：实际条件语句用于陈述语气，可能会发生假设情况。其中if代表意义。时态关系：句型：条件子句主语通常是现在shall/will动词原型例如：If he comes，he will bring his violin。典型示例：the volleyball match will be

2、 put off it实际条件语句的主子句是未来，从属子句通常是当前诗。注：(1)在实际条件语句中，主句不能用be going to表示未来。shall，will。(错误)If you leave now，you are never going to regret it.You will never regret it。(2)表示真理时，主谓动词不使用shall(威尔)动词原形，而是直接使用一般现动词形式。(。2，不切实际的条件语句：(1)时态：可以表示科举、现在和未来的情况。它的基本特征是时态后退。a .与目前事实相反的假设。文章模式：条件式(would)主要是科举should(would)

3、动词原型。例如if they were here，they would help you .b .表示与科举事实相反的假设。文章模式：条件子句短语过去完成时，should (would) have科举分词If she had worked harder，She would have succeeded . the rice would not have been burnt If yould，if he had come yesterday，I should/would have told him about it。含义：He did not come yesterday So I did n

4、ot tell him about it . if had not been ill and missed many classes，He would have made greater progress。含义：he was ill and missed many lessons，so he did not make greater progress。c .对未来的虚拟表达：文章模式：条件句主句通用科举should动词原型were不定式动词原型should动词原型if you succeeded，Everything would be all right . if you should suc

5、ceed Everything，3，混合条件语句If you had asked him yesterday，you would know what to do now。)If it had rained last night(科举)，it would be very cold today(当前)，4，虚拟条件语句的翻转筹码：如果虚拟条件语句的子句包含were、should或had=if they were here now，they could help us。had you come earlier，You would have met him。=if you had come earli

6、er，you would have met him . should it rain，the crops would be saved。=were it to The crops would be saved。注：在虚拟语气的从句中，动词be的科举时态总是“were”，不使用was，即在句子中用were代替be。If I were you，I would go to look for him。如果我是你，我就去找他。If he were here，everything would be all right。如果他在这里，一切都会好起来的。典型示例：_ _ _ _ _ _ _ to do the

7、 work，I should do it some other day . a . if were I b . I were c . were I d . was I回答c.但是要注意，在虚拟条件副词部分，省略连接词的倒装形式的句子的开头不能作为动词的缩略语来写。如果我们可以说Were I not to do，Werent I to do。5，特殊的虚拟语气语：不能说should。(1)在it is demanded/necessary/a pity that结构中，主语的谓语动词是should动词原型，should可以省略。文章模式：suggested it is important tha

8、t(should)do a pity，(1) suggested，ordered，proposed，required，demann.the guard at gate insisted that everybody obey the rules。判断错误：(错误)you pale face suggests that you(should)be ill。(示例)your pale face suggests that you are ill。(错误)Be wrong。(示例)I insisted that you were wrong。(3)剽窃，同位素的应用。Suggestion、propo

9、sal、idea、plan、order、advice等名词后的表语从句、东魏语从句要使用虚拟语气，即(should)动词原形。my idea wish that we(should)get more people to attend the conference . I make a proposal that we(should)hold a meeting next week(hold a meeting next week)宾语从句的动词形式如下。实态wish后句动作先于主句动词动作，现在在过去诗(be的过去形式是were)后句动作和主句动作同时发生时，在科举完成时(had科举分词)后实

10、现的可能性不大的愿望以后在would/could动词原型(例如：i Wish I Were)前实现。He wished he hadnt said that。他希望他不要说那种话。I wish it would rain tomorrow。希望明天下雨。(2)Wish to do表示法。Wish sb。/sth。to do I wish to see the manager。=I want to see the manager。I wish the manager to be informed at once。(=I want Only if表示“仅”。If only表示“如果不介意的话”。I

11、f only还可以用于陈述语气。I wake up only if the alarm clock rings。只有闹钟响的时候才醒。If only the alarm clock had rung。希望闹钟响了。If only he comes early。希望他早点回来。8，It is (high) time that。It is (high) time that后面的子句谓词动词应该使用过去式或should和动词原形，但should省略，渡边杏。it is time that the children went to bed . it is high time that the chil

12、dren should go to bed .9，need“不必做”和“做渡边杏”。Didnt need to do说：“过去不需要做任何事情，实际上不做。”Neednt have done说，过去不必做任何事，但实际上做了。例如，John went to the station with the car to meet Mary，so she didnt need to walk back home .约翰开车去车站接玛丽，所以不必步行回家。John went to the station with the car to meet Mary，so she need nt have walked back home .约翰开车去车站接玛丽，所以不必步行回家。(玛丽没有见到约翰的车，而是步行回家。)，典型示例：there was plenty of time.she _ _ _。a . must nt have hurried b . could nt have hurrie
