(他给我写了一封信)有时可把介词to或for加在间接宾语前构成短语,放在直接宾语后面,来强调间接宾语。如：He wrote a letter to me . (他给我写了一封信)5、定语修饰名词或代词,通常由形容词、代词、数词等担任。如：Shanghai is a big city .(上海是个大城市)6、状语用来修饰动词、形容词、副词,通常由副词担任。如：He works hard .(他工作努力)7、宾语补足语用来说明宾语怎么样或干什么,通常由形容词或动词充当。如：They usually keep their classroom clean.(他们通常让教室保持清洁) / He often helps me do my lessons.(他常常帮我做功课) / The teacher wanted me to learn French all by myself.(老师要我自学法语)同位语通常紧跟在名词、代词后面,进一步说明它的情况。如：Where is your classmate Tom ?(你的同学汤姆在哪里？)。二、名词：1、英语名词可分专有名词和普通名词两大类：1、专有名词是个别的人、地、物、团体、机构等的专用名称。专有名词中实词的第一个字母要大写。如：Beijing, Tom, the Peoples Republic of China(中华人民共和国)专有名词如果是含有普通名词的短语,则必须使用定冠词the。如：the Great Wall(长城)姓氏名如果采用复数形式,则表示该姓氏一家人(复数含义),如：the Greens( 格林一家人)。2、普通名词是许多人或事物的共有名称。如：pupil, family, man, foot.普通名词又分为可数名词和不可数名词。可数名词是可以用简单的数词进行计数的名词,如： box, child, orange；不可数名词是不可以用简单的数词进行计数的名词。如：water, news, oil, population, information .2、英语可数名词的单复数：英语可数名词有单数和复数两种形式。1、名词由单数变复数的基本方法如下：在单数名词词尾加s。如：map maps,boy boys,horse horses, table tables.s,o,x ,sh,ch结尾的词加es.如：classclasses, boxboxes, heroheroes, dishdishes, benchbenches.注：少数以o结尾的词,变复数时只加s。如：photophotos, pianopianos.以辅音字母加y结尾的名词,变y为i,再加es。如：familyfamilies, citycities, partyparties.以f或fe结尾的名词,变f或fe为v,再加es。如：shelfshelves, wolfwolves, lifelives, knifeknives.2、不规则变化：manmen, womanwomen, sheepsheep,toothteeth, fishfish, childchildren, oxoxen, goosegeese不可数名词一般没有复数形式,说明其数量时,要用有关计量名词。如：a bag of ricetwo bags of rice, a piece of paperthree pieces of paper, a bottle of milkfive bottles of milk. 3、名词所有格：1、名词所有格表示所属关系,相当于物主代词,在句中作定语、宾语或主语。其构成法如下：(1)表示人或其它有生命的东西的名词常在词尾加s。如：Childerns Day(儿童节), my sisters book(我姐姐的书)(2)以s或es结尾的复数名词。只在词尾加。如：Teachers Day(教师节)(3)有些表示时间、距离以及世界、国家、城镇等无生命的名词,也可在词尾加s. 如：todays newspaper(今天的报纸), ten minutes break(十分钟的课间休息),Chinas population(中国的人口).(4)无论表示有生命还是无生命的东西的名词,一般均可用介词of短语来表示所有关系。如：a fine daughter of the Party(党的好女儿).2、注解： s还可以表示某人的家或者某个店铺,如：my aunts(我阿姨家), the doctors(诊所) 两人共有某物时,可以采用 A and Bs 的形式,如：Lucy and Lilys bedroom(露西和丽丽合住的卧室) “of+名词所有格/名词性物主代词”,称为双重所有格,如：a friend of my fathers(我父亲的一位朋友), a friend of mine(我的一位朋友)4、名词或代词作主语时和谓语之间的单复数的一致问题：1、谓语和谓语基本保持单复数的一致,即：主语是可数名词单数或不可数名词时,谓语动词用单数形式：如：The computer was a great invention.(计算机是个了不起的发明)The water in the glass is very cold.(玻璃杯里的水很冷)2、集体名词(如family, class, team, group, row, police, school等)做句子主语时,1如果表示整体概念,则谓语用单数形式,如：Class Three is a very good class.(三班是好班)2如果表示其中的所有成员时,则谓语用复数形式,如：Class Three have a map of China.(三班有张中国地图)3、Chinese, Japanese, fish, sheep, people等表示单个时谓语用单数,表示许多时,谓语用复数。如：There is a sheep in the yard.(院子里有只绵羊) / There are some sheep in the yard.(院子里有一些绵羊)4、maths, news等虽然有s结尾,但不是复数,因此谓语仍用单数：The news is very exciting. (这个消息令人兴奋)5、glasses, shoes, socks, trousers, gloves等名词往往用复数形式,故谓语用复数。如：The trousers are very cheap and I want to take them.(裤子很便宜,我想买)6、a lot of 后跟名词复数时谓语用复数形式,跟不可数名词时谓语用单数形式。如：A lot of students are playing baseball now.(现在有许多学生在打垒球) A lot of time was wasted on that work.(大量的时间花在了那个工作上)(被动句)7、and 连接两个名词做主语时,谓语原则上用复数,但是两个名词若构成一个整体事物时,谓语则用单数。如：The teacher and his son are picking apples now.(老师和他的儿子在摘苹果) / Fish and chips is very famous food. (鱼和薯条是一种出名的食品)8、 there be 句型中be的单复数一般由靠近的名词决定。如：There is a table and four chairs in the room.(房间里有一张桌子和四张椅子)9、用bothand连接两个事物做主语时,谓语一般用复数。如：Both you and I are required to be here tomorrow.(你和我明天要求都来)10、主语中含有with的短语时,谓语单复数由with之前的人物决定。如：A woman with a 7-year-old child was standing at the side of the road. (一名妇女带着一个七岁的孩子(当时)就站在路边)”。十一、句子成分：主语、谓语、宾语、表语、定语、宾语补足语和状语1、主语：(1)由名词、代词(人称代词用主格)、动词不定式、动名词等充当,说明动作是“谁”发出的。如：The painter painted a very nice picture. (画家画了一幅漂亮的画。) / They fought against SARS bravely.

(那块烤馅饼已经变坏。) / (2)谓语动词必须反映出人称、单复数、时态等信息,谓语动词往往由下列词语依序排列构成：情态动词+时态助动词+语态助动词+主要动词(不一定全部出现)。(见动词的时态和语态构成表)记住：谓语部分第一个动词往往是变形动词。如：I am sorry I am making so much noise but I have to.

(listen不是及物动词,故加to。) / Can you hear anything exciting?(你能听到什么令人兴奋的消息吗？)(3) 宾语一般放在及物动词或介词的后面,但是在疑问句中,如果宾语是疑问词,则宾语要放在句首。介词的宾语如果是疑问词,则可以放在介词后或句首。如：What did he see?
