Unit9 知识点总结 Section A ①---What’s your favorite subject? ---My favorite subject is science. (1) favorite用作形容词时,意为“最喜欢的,特别喜欢的”,可在句中作定语修饰名词。注意:favorite与like都有“喜爱”的意思,但它们的磁性不同个,在句子中所处的位置也不同,favorite常与like...best互换作用。例如: His favorite sport is basketball.= He likes basketball best. What is your favorite color?= What color do you like best? (2)favorite用作名词时,意为“特别喜欢的人或物”,是可数名词。例如: These movies are my favorites. ②---Why do you like science? ---Because it’s interesting. (1) 疑问词why意为“为什么”,用来提问原因,其答句常用because引导的句子来回答。例如: ---Why are you late for school? ---Because it is raining. (2)because是连词,意为“因为”,其后接句子,用来说明原因。在汉语中,表示因果关系一般用“因为……,所以……”,但在英语中,because(因为)与so(所以)在一个句子中不能同时出现。例如: 因为我太忙,所以我不能同你出去。 误:Because I am very busy, so I can’t go out with you. 正:Because I am very busy, I can’t go out with you. 正:I am very busy, so I can’t go out with you. ③---Who is your P.E.teacher? ---Mr Hu. who是疑问代词,它引导的特殊疑问句对人提问,意为“谁”,可以作主语。who作主语时,用“who+谓语+其他?”的句型,并且who通常被认为是第三人称单数形式,谓语动词要与其保持一致。例如: ---Who helps you do housework? ---Mary. who作表语时,用“who+be+主语?”的句型,系动词be随主语的数而变化:主语是第三人称单数时用is,主语是复数时用are。例如: ---Who’s this man? ---He’s Jack’s father. ---Who are these girls? ---They are Jean and Kate. ④He always plays games with us. 句中的play with...意为“和……一起玩”。例如: Can you come out to play with me? play with还可以意为“玩弄,玩耍”。例如: The boy is playing with his toy car. Section B ⑤---When is the class? ---It’s on... 介词on意为“在……时候”,常用于星期、日期前或用于前有描绘性修饰语或带有of等引导的后置修饰语的morning,afternoon,evening,night,day前,也饿用于公共节假日前。例如: I have a rest on Sundays. What are you going to do on Monday morning? He was born on the night of May 10th. On Children’s Day, all the children are very happy. ⑥I’m really busy! (1) busy是形容词,意为“忙的;繁忙的”,在句中可用作表语,也可用作定语。例如: We are very busy now. He is a busy man. (2) busy的常用短语: be busy doing sth.意为“忙于做某事”。例如: He is busy doing his homework. be busy with sth.意为“忙于某事”。例如: My sister is busy with her lesson. 【提示】busy虽然有“忙”的意思,但busy只表示人“忙”,而不表示工作“忙”。所以主语一般用表示人的名词或代词,而不用work。 试译:我父亲的工作很忙。 误:My father’s work is very busy. 正:My father is very busy. ⑦It’s difficult, but interesting. (1) difficult作形容词,意为“困难的,艰难的”。例如: Nothing is difficult to a man who has will. This question is too difficult for me. (2) but是并列连词,意为“但是;可是”,表示转折意义。例如: She’s very tall, but she doesn’t like playing basketball. ⑧I have an art lesson for two hours. for为介词,后面加一段时间,表示“持续多久的时间”。例如: I do my homework for three hours every day. 易错易混全解 1. 特殊疑问句 (1) 用来提出问题的句子,叫疑问句。疑问句按其所提出的不同问题可分为四种:一般疑问句、特殊疑问句、选择疑问句和反义疑问句。 特殊疑问句时以疑问代词或疑问副词开头,对句子中的某一部分进行提问的句子。它的基本结构是:特殊疑问词+一般疑问句语序。但是如果疑问词或由其所修饰的词在句子中做主语时,就用陈述句语序。回答时,针对问句中的代词或副词来回答,不用yes或no来回答。它的回答应是:问什么,答什么。 常用的特殊疑问代词有:what,which,who,whom,whose;疑问副词有:when,where,why,how等。 (2) 特殊疑问句的构成有两种情况: ①当疑问词或其他修饰的词不作主语时,用疑问句语序,即疑问词+一般疑问句,这是最常见的情况。例如: Where’s my English book? ②当疑问词或其所修饰的词作主语时,用陈述句语序。例如: Who teaches you English? 具体类型有: ①对指物名词提出疑问,疑问词用what。例如: The twins make a kite.(对画线部分提问) What do the twins make? Mrs Turner asks her son to buy some eggs.(对画线部分提问) What does Mrs Turner ask her son to buy? ②对指人的名词或代词提问,疑问词用who。例如: Who is that woman? Who’s that boy? ③对具体地点提出疑问,疑问词应用where。例如: The pupils have a picnic at the foot of the hill.(对画线部分提问) Where do the pupils have a picnic? ④对具体时间提出疑问,如in the morning,last Sunday等,疑问词常用when;对具体几点钟提问,疑问词常用what time。例如: When can I see you? What time is it now? ⑤对表示原因的句子提问,如because引导的句子,疑问词应用why。例如: Why don’t you say hello to him? ⑥对方式或程度等提出疑问,用疑问词how。例如: How do you go to school? ⑦对数量提出疑问,疑问词为how many/how much,要注意how many必须跟可数名词的复数形式,how much跟不可数名词。例如: How many books do you have? How much milk is there in the glass? ⑧对价格提出疑问,疑问词用how much。例如: How much is the coat? ⑨另外,对日期、星期提出疑问,则分别用: What’s the date? What day is it? 【提示】我们已经学过的特殊疑问句有: ①What’s this /that in English? ②What color is it? ③What’s your name? ④What’s your phone number? ⑤What time do you go to school? ⑥When is your birthday? ⑦Where’s my schoolbag? ⑧How old are you? ⑨How much are these pants? ⑩Why do you like math? 2. Mr.;Mrs;Miss;Ms. Mrs. “夫人”,用于称呼已婚女性 Mr. “先生”,用于男子姓前 Miss “小姐”,用于称呼未婚女性 Ms. “女士”,用于称呼不明婚姻状况的女性 3.some;any (1)some和any作定语时,既可以修饰可数名词,也可以修饰不可数名词。Some多用于肯定句,意为“一些;若干”。例如: Tom has some good friends at school. There is some milk in the glass. (2) any多用于否定句、疑问句,有“任何的;一些”的意思。 There aren’t any trees behind the house. Is there any bread on the table? 【提示】①any多用于肯定句中,表示“任一”。例如: Any man knows that. ②some也可用于表示提出建议、邀请或请求等的疑问句中。例如: Can I have some meat? Will you give me some pencils?
