1、高一英语公开课课件高一英语公开课课件【一】分词作状语的区别（1）现在分词与过去分词作状语的区别。现在分词做状语与过去分词做状语的最主要区别在于两者与所修饰的主语的主动与被动关系的区别。1）现在分词作状语时，现在分词的动作就是句子主语的动作，它们之间的关系是主动关系。He went out ，shutting the door behind him.他出去后将门随手关上。Not knowing what to do, he went to his parents for help.由于不知如何办是好，他去找父母帮忙。2）过去分词作状语时，过去分词表示的动作是句子主语承受的动作，它们之间的关系是被

6、orking in the factory are well-paid.在这家工厂工作的工人报酬很好2过去分词做定语从功能上看，过去分词做定语表示1）被动（及物）；2）完成（不及物）。做定语：相当于一个定语从句（被动），有时侯也表示完成的The broken window was repaired this morning.The window broken yesterday was.The window that/which was broken yesterday was.昨天被打破的玻璃今早被修好了The sold hamburgers are not to my taste.The

10、从句的省略一般说来省略现象多出现在下列五种状语从句中：由 when ,while ,as ,before, after , till, until, once等引导的时间状语从句；由whether ,if , unless 等引导的条件状语从句；由 though , although ,even if ,whatever等引导的让步状语从句；由 as ,than 等引导的比较状语从句；由as, as if , as though 等引导的方式状语从句。上述状语从句在省略时，并非任何成分都可以省略而是遵循下面原则：（1）当状语从句的主语与主句的主语一致时且从句中含有BE动词的某种形式时，可以省略

11、状语从句的主语和系动词be ，这时从句中可出现如下结构： 连词（as, as if , once）+ 名词如：Once (he was)a worker ,Pang Long now becomes a famous singer .庞龙曾经是个工人，现在变成一位著名的歌手。连词（ though, whether , when）+形容词如：Work hard when (you are) young ,or youll regret.趁年轻要努力学习，要不然你会后悔的。连词(whether, as if ,while )+介词短语如：He looked everywhere as if (he

14、(it is) necessary ,youd better not refer to the dictionary.如果没有必要，你最好不要查字典。各种状语从句的省略现象列举如下：一、时间状语从句中的省略When (she was) very young, she began to learn to play the piano. 她很小时，就开始学习弹钢琴。While (I was) at college, I began to know him, a strange but able student. 我在上大学时就开始认识他，一个奇怪但有能力的学生。When arriving, sen

16、know the result as soon as(it is) possible. 你应尽快让我们知道结果。注：as在引导时间状语从句时，没有这种省略现象。我们不可说As walking, she found a nice shining thing on the ground.二、地点状语从句中的省略地点状语从句的省略常用下列结构：where(ver) possible, where(ver) necessary,Lay these books where possible you can find them easily. 把这些书放在你可能容易找到的地方。Put in article

17、s wherever necessary in the following passages. 在下列文章中需要的地方填入冠词。三、条件状语从句中的省略常用的句型是：if necessary, if possible, if true, if anyone等。如：Send the goods now if (they are) ready. 货物如果准备好了，请送过来。He will come if (he is) asked. 如果叫他来，他就来。If (it is) necessary, ring me at home. 如果有可能，朝我家里打电话。Come along with me i

19、gh sometimes (he is) rather dull. 他真是个好人，尽管有时有点无聊。Even if (I am ) invited to, I wont go to such a bad lecture. 即使邀我去，我都不想听如此坏的报告。五、比较状语从句中的省略She can play the piano just as wonderfully as you (do). 她钢琴弹的我你弹的一样好。She has finished the work earlier than (it has been ) expected.【四】with复合结构with结构是许多英语复合结构中

20、最常用的一种。学好它对学好复合宾语结构、不定式复合结构、动名词复合结构和独立主格结构均能起很重要的作用。本文就此的构成、特点及用法等作一较全面阐述,以帮助同学们掌握这一重要的语法知识。一、 with结构的构成它是由介词with或without+复合结构构成,复合结构作介词with或without的复合宾语,复合宾语中第一部分宾语由名词或代词充当,第二部分补足语由形容词、副词、介词短语、动词不定式或分词充当,分词可以是现在分词,也可以是过去分词。With结构构成方式如下：1. with或without-名词/代词+形容词；2. with或without-名词/代词+副词；3. with或with

21、out-名词/代词+介词短语；4. with或without-名词/代词 +动词不定式；5. with或without-名词/代词 +分词。下面分别举例：1、 She came into the room,with her nose red because of cold.(with+名词+形容词,作伴随状语)2、 With the meal over , we all went home.(with+名词+副词,作时间状语)3、The master was walking up and down with the ruler under his arm。(with+名词+介词短语,作伴随状语

22、。) The teacher entered the classroom with a book in his hand.4、He lay in the dark empty house,with not a man ,woman or child to say he was kind to me.(with+名词+不定式,作伴随状语) He could not finish it without me to help him.(without+代词 +不定式,作条件状语)5、She fell asleep with the light burning.(with+名词+现在分词 ,作伴随状语

23、) Without anything left in the cupboard, shewent out to get something to eat.(without+代词+过去分词,作为原因状语)二、with结构的用法在句子中with结构多数充当状语,表示行为方式,伴随情况、时间、原因或条件(详见上述例句)。With结构在句中也可以作定语。例如：1.I like eating the mooncakes with eggs.2.From space the earth looks like a huge water-covered globe with a few patches of

24、land sticking out above the water.3.A little boy with two of his front teeth missing ran into the house.三、 with结构的特点1. with结构由介词with或without+复合结构构成。复合结构中第一部分与第二部分语法上是宾语和宾语补足语关系,而在逻辑上,却具有主谓关系,也就是说,可以用第一部分作主语,第二部分作谓语,构成一个句子。例如： With him taken care of,we felt quite relieved.(欣慰)(He was taken good care

25、of.) She fell asleep with the light burning. (The light was burning.) With her hair gone,there could be no use for them. (Her hair was gone.)2. 在with结构中,第一部分为人称代词时,则该用宾格代词。例如： He could not finish it without me to help him.四、 几点说明：1. with结构在句子中的位置： with 结构在句中作状语,表示时间、条件、原因时一般放在句子前面,并用逗号与句子分开；表示方式和伴随状

26、况时一般放在句子后面,不用逗号分开。若with结构作定语,则放在所修饰的名词之后,一般不用逗号隔开。2. with结构作状语时,不定式、现在分词 、和过去分词的区别： 在with结构中,不定式、现在分词作宾补,表示主动,但是不定式表示将要发生的动作,而现在分词表示正在发生或发生了的动作；过去分词表示被动或完成。例如： With the boy leading the way,we found he house easily.(小男孩已领过路)With the boy to lead the way,we will find the house easily tomorrow.(小男孩明天将领路

27、)He lay on the bed with the bedroom door shut.(寝室被关着)3. with结构与一般的with短语的区别： with结构具有上述功能和特点,而介词with+名词或代词(组)组成的一般的with短语在句子中可以作定语和状语。作状语时,它能表示动作的方式、原因,但不能表示时间、伴随和条件。在一般的with短语中,with后面所跟的不是复合结构,也根本没有逻辑上的主谓关系。4. with结构与独立主格结构的关系： with结构属于独立主格结构,但在结构上,with结构由介词with或without引导,名词前有冠词、形容词、所有格代词或其它词类所修饰,结

28、构较松散；而独立主格结构没有with或without引导,结构严密,名词前可用可不用修饰语。在句法功能上,with结构可以作定语,独立主格结构则不能；独立主格结构通常在句中作状语,但也可以作主语,而with结构则不能。独立主格在口语中不常用,往往由一个从句代替,而with结构较口语化,较常用。例如：There were rows of white houses with trees in front of them.(with+复合宾语结构,在句中作定语)A strong man working a whole day could not jump this high.(名词+现在分词构成的独

29、立主格结构,作主语)The boy said,turning to the man,his eyes opened wide and his hand raised.(独立主格结构,表示伴随状况或行为方式,作状语)Then last night,I followed him here,and climbed in,sword in hand.(名词+介词短语构成的独立主格结构,作状语,表示伴随情况) board, she went out to get something to eat.(without+代词+过去分词,作为原因状语)1.
