flew.,不，我们是飞去。,2.,主语,+,连系动词,+,表语,也叫做主系表，这种句型称为主系表结构，其实连系动词在形式上也是一种谓语动词，但实质上表语成了谓语，,例：,The milk went sour.,牛奶变酸了。,She became a

go.,我将让他去。,（不定式,go,用作补语）,注意：,有时两个或更多的并列主语拥有一个共同的谓语，甚至并列有两个主语和两个谓语，这样的句子仍然是简单句，,例：,China and other countries in the east Asia are developing rapidly.,中国和东亚其它国家正在迅速地发展。,（,China and other countries,并列主语）,Mr.Wang and I often work together and help each other.,王先生和我常在一起工作互相帮助。并列句,两个或两个以上的简单句用并列连词,and,but,so,for,or,等连在一起构成的句子，叫做,并列句,根据并列分句之间的不同关系，并列句可分为,4,种,:,第一种：表并列关系,（此类并列连词有,and,bothand,neithernor,as well as,not only.but(also),等）,如：,He likes

students,(,who dont study hard,),will not pass the exam.,先行词,定语从句,主句,:The students will not pass the exam.,2.,The woman,(,whom you saw in the park,),is our English teacher.,先行词 定语从句,主句,:The woman is

very,等修饰时,c,、先行词是,all,much,anything,something,nothing,等不定代词,d,、句是以,who/which,开头的特殊疑问句时,e,、当先行词在定语从句中作表语时,2,、,which,指物，作主语或宾语。,3,、,who,whom,指人,who,作主语,whom,作宾语。,4,、,that,which,whom,在定语从句中作宾语时,可省去。,5,、关系副词,when,指时间,关系副词,where,指地点,在定语从句中作,状语,。即使先行词是时间地点,若作从句中的宾语，只能用关系代词,that,which.,6,、,“,介词关系代词”即“介词,whom/which”,引导定语从句应注意介词的选用至少要考虑以下的两个因素,A.,与先行词的搭配关系：,例：,I will never forget the day,on which,I joined the army.,B.,与谓语动词的搭配习惯,例：,Have you found the book for which I paid 29 US dollars?,状语从句,是副词性从句，它在句子中担任状语，修饰主句的动词、形容词或副词。根据修饰的方面，状语从句可以分为以下九种：,时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、方式状语从句、让步状语从句和比较状语从句。,一、时间状语从句,常用引导词：,when,as,while,as soon

us.,在句子中起名词作用的句子叫,名词性从句,名词性从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为,主语从句、表语从句、宾语从句和同位语从句,。,一 主语从句：主语从句在整个句子中作主语。,(1),不同于其它的连词，它不充当句子的成分，只是单纯的连接词，通常不可以省略。分句置于句首时，,that,绝对不可以省略。,That the driver could not control his war was obvious.It was obvious that the driver could not control his

be,三,.,宾语从句：及物动词，形容词和介词后加宾语从句作其宾语。,宾语从句时态与主句相呼应，但宾语从句表示的是客观真理或普遍现象除外,The teacher told us that the earth moves around the sun,(2),连词,whether,和,if,可以互换，但注意下列情况 连词后紧跟,or not,时用,whether,I want to know whether or not they will come.,作,介词宾语是用,whether,引导宾语从句,He was interested in whether he saw her there.,连接词后直接加不定式，,不能用,if,只能用,whether,He doesnt know whether to stay or not.,如果,宾语从句是否定时,，一般用,if,引导,I

come.,Word came that Napoleon would come to inspect them.,There is no possibility that.,(2)that,引导的同位语从句与定语从句的区别：在,同位语从句,中，,that,不可以省略,，不作成分,;,定语从句的关系代词,that,在定语从句作成分，,作宾语时可以省略,We are interested in the news that some foreigners would visit our school.,We are interested in the news that he told us.,when,where,引导的同位语从句与定语从句的区别：在定语从句中，,when,where,前有分别表示时间、地点的先行词；而在同位语从句中无此对应关系,They have no idea at
