1、九年级英语Grammar知识精讲一. 本周教学内容: Grammar(九年级上册)二. 教学重难点:(一)并列句(Compound Sentence)并列句是由并列连词把两个或两个以上的简单句连在一起构成的句子,连词前可用逗号,也可不用逗号。这些连接词在句中起连接句子的作用,同时它们还表示并列、条件、结果、转折、让步和因果关系。 1. 表示并列的连词有:and,not only,but also,neithernor,so,on one hand,on the other hand等。如:这是我们的房子,而那是他的房子。This is our house and that is his. 上个
2、星期他没去游泳,我也没去。He didnt go swimming last week, neither did I.他不但聪明而且勤奋。He is not only clever, but also hard-working.一方面我得工作,另一方面我又要接待许多来访者。On one hand I have to work, on the other hand I have a lot of visitors. 2. 表示条件或结果关系的连词有and,or等。再说一句话,我就打扁你。One more word and Ill beat you flat. 赶快,否则你会迟到的。Hurry u
3、p, or you will be late.3. 表示转折和让步关系的连接词有:but,while,however,yet,still等。如:他英语好,但数学差。He is good at English, but he is weak in maths.虽然我没有成功,但我绝不会放弃任何希望。I havent succeeded, however, Ill never give up any hope.汤姆每天做家务,而他的妹妹什么也不做。Tom does housework every day while his sister does nothing.4. 表示因果关系的连接词:for
4、,so等。如:我得了重感冒,所以今天我没去上学。Ive got a very bad cold, so I didnt go to school today.地面很湿,因为昨晚下雨了。The ground is very wet, for it rained last night.二. 定语从句以一个从句的形式修饰或者限制主句中的名词、代词、短语等,叫定语从句。定语从句通常由关系代词和关系副词引导,被定语从句所修饰的词叫先行词。引导定语从句的关系代词有:who指人,在从句中作主语或宾语;whom指人,在从句中作宾语;whose指人或物,在从句中作定语;that指人或物,在从句中作主语或宾语;w
5、hich指物,在从句中作主语或宾语。关系代词作宾语时可以省略。那个和老师讲话的女士是我的母亲。The woman who is talking with our teacher is my mother.(作主语)医生是关照人们健康的人。The doctor is a person who looks after peoples health.(作主语)你刚才见到的那个人是我叔叔。The man(whom)you saw just now is my uncle.(作宾语,可省略)这就是你要找他谈话的那个学生。This is the student(whom)you want to talk
6、with.(作宾语,可省略)那些被点了名的学生站起来了。The students whose names were called stood up.(作定语)我喜欢窗户朝南开的房子。I like the houses whose windows face the south.

7、that/which lies on the table is mine. (作主语)拓展:1. 在英语中先行词指人,作宾语时既可以用whom,也可以用who和that,也可以省略。2. that和which的区别:(1)下列情况只用that不用which。当先行词前有序数词、形容词的最高级以及其他限定词时,只用that不用which。这是我有生以来的第一次旅行。This is my first trip that I have made in my life.他参观过的最美的地方是张家界。The most beautiful place that he has visited is Zhan
8、g jia jie.这是我给他的唯一的礼物。This is the only gift that I have given him.当先行词的不定代词时,如:anything,everything,nothing,all,none,much,little等词时,只用that不用which。她拿走了属于她的一切东西。She took away everything that belongs to her.我将告诉你一些昨晚发生的奇怪的事情。Ill tell you something strange that happened yesterday evening.当有两个以上的先行词(一个指人,
9、另一个指物时),也只用that不用which。老人谈起他能记得的人和事。The old man talked about the persons and things that he could remember.(2)下列情况只用which不用that。在非限定性定语从句中,只用which不用that。他又迟到了,这使老师很生气。He came to school late again, which made his teacher very angry.当关系代词前有介词,先行词指物时,只用which不用that。我正在写的这支钢笔不是我的。The pen with which I am

11、me.你告诉了老师你迟到的原因吗?Have you told the teacher the reason why you were late?注意:有时候先行词指时间或地点,但关系代词在从句中作主语或宾语,这时只用which和that。这是我们十年前参观过的那所大学。This is the university that/which we visited ten years ago.(作宾语)这就是我们十年前学习过的学校。This is the school where we studied ten years ago.(作地点状语)我将永远忘不了我们在一起度过的那些日子。Ill never
