pep 小学英语毕业总复习知识点汇总(一)2011-05-14 22:51:11| 分类: 默认分类 | 标签: |字号大中小 订阅 一:学生易错词汇1. a, an 的选择: 元音字母开头的单词用 an,辅音字母开头的单词用 a.2. am , is , are 的选择: 单数用 is , 复数用 are. I 用 am , you 用 are.3. have , has 的选择: 表示某人有某物。单数用 has , 复数用 have. I ,you 用 have .4. there is, there are 的选择 :表示某地有某物,某人。单数用 there is , 复数用 there are.5. some, any 的选择:肯定句用 some, 疑问句和否定句用 any.6. 疑问词的选择:what (什么) who (谁) where (哪里) whose (谁的) why(为什么)when(什么时候)which (哪一个)how old ( 多大) how many (多少)how much(多少钱)二:形容词比较级详解当我们需要对事物作出比较时,需要用到比较级。比较级的句子结构通常是:什么 + 动词 be (am , is , are ) + 形容词比较级 + than(比) + 什么 ,如:Im taller and heavier than you. (我比你更高和更重。 )An elephant is bigger than a tiger. (一只大象比一只老虎更大。 )形容词的比较级是在形容词的基础上变化而来的,它的变化规则是: 一般的直接在词尾加 er ,如 tall - taller , strong - stronger , 以 e 结尾的,直接加 r ,如 fine finer , 以辅音字母加 y 结尾的,先改 y 为 i 再加 er,如 funny - funnier 双写最后的字母再加 er,如 big bigger, thin thinner ,hot hotter注意 比较的两者应该是互相对应的可比较的东西。典型错误:My hair is longer than you.(我的头发比你更长。 )比较的两者是我的头发、你(整个人) ,那么比较的对象就没有可比性。应该改为:My hair is longer than yours. 或 My hair is longer than your hair.比较级专项练习: 一、从方框中选出合适的单词完成句子 heavy tall long big(1) How is the Yellow River?(2) How is Mr Green? Hes 175cm.(3) How are your feet? I wear size 18.(4)How is the fish? Its 2kg.二、根据句意写出所缺的单词(1) Im 12 years old. Youre 14. Im than you.(2) A rabbits tail is than a monkeys tail.(3) An elephant is than a pig.(4) A lake is than a sea.(5) A basketball is than a football.三、根据中文完成句子.(1) 我比我的弟弟大三岁. Im than my brother.(2) 这棵树要比那棵树高. This tree than that one.(3) 你比他矮四厘米. You are than he.(4) 谁比你重? than you?四、根据答句写出问句(1) Im 160 cm.(2) Im 12 years old.(4) Amys hair is 30 cm long.三:动词过去式详解 动词的过去式的构成规则有:、规则动词 一般直接在动词的后面加 ed:如worked , learned , cleaned , visited以 e 结尾的动词直接加 d:如lived , danced , used 以辅音字母加 y 结尾的动词要改 y 为 i 再加 ed(此类动词较少)如study studied carry carried worry worried (注意 play、stay 不是辅音字母加 y,所以不属于此类) 双写最后一个字母(此类动词较少)如stopped 、不规则动词(此类词并无规则,须熟记)小学阶段要记住以下动词的原形和过去式:sing sang , eat ate , see saw , have had , do did , go went , take took , buy bought , get got , read read ,fly flew , am/is was , are were , say said , leave left , swim swam , tell told , draw drew , come came , lose lost , find found , drink drank , hurt hurt , feel felt四:动词现在分词详解 动词的 ing 形式的构成规则: 一般的直接在后面加上 ing , 如 doing , going , working , singing , eating 以 e 结尾的动词,要先去 e 再加 ing,如 having , writing 双写最后一个字母的(此类动词极少)有:running , swimming , sitting , getting五:人称和数人称代词主格 宾格 物主代词单数 I(我) me my(我的)第一人称 复数 we(我们) us our(我们的)单数 you(你) you your(你的)第二人称 复数 you(你们) you your(你们的)he(他) him his(他的)she(她) her her(她的)单数it(它) it its(它的)第三人称复数 they(他们/她们 /它们) them their(他们的 /她们的/它们的)六:句型专项归类1、 肯定句:是指用肯定的语气来陈述的句子,如:Im a student. She is a doctor. He works in a hospital. There are four fans in our classroom. He will eat lunch at 12:00. I watched TV yesterday evening. 2、否定句:含有否定词或表示否定意义词的句子,如:Im not a student. She is not (isnt) a doctor. He does not (doesnt) work in a hospital. There are not (arent) four fans in our classroom. He will not (wont) eat lunch at 12:00. I did not (didnt) watch TV yesterday evening. 注意 小结:否定句主要是在肯定句的基础上加上了否定词 “not”。有动词 be 的句子则“not”加在 be 后面,可缩写成 “isnt,arent”,但 am not 一般都分开写。没有动词 be 的句子则要先在主要动词的前面加上一个助动词(do,does,did) ,然后在它后面加上“not”,你也可以把它们缩写在一起如“dont , doesnt , didnt ) 。这三个助动词要根据人称和时态来选择,其中“does”只用于一般现在时主语是第三人称单数的情况,而 “did”只用于一般过去时,不论主语是什么人称和数,都用“did” 。3、一般疑问句:是指询问事实的句子,此类句子必须用“yes”,或“no”来回答。如:Are you a student? Yes, I am / No, Im not. Is she a doctor? Yes, she is. / No, she isnt. Does he work in a hospital? Yes, he does. / No, he doesnt. Are there four fans in our classroom? Yes, there are. / No, there arent. Are you going to buy a comic book tonight? Yes, I am. / No, I am not. (Yes, we are. / No, we arent.)Will he eat lunch at 12:00? Yes, I will. / No, I will not(wont). Are they swimming? Yes, they are. / No, they arent.Did you watch TV yesterday evening? Yes, I did. / No, I didnt.注意 小结:一般疑问句是在肯定句的基础上,把动词 be 调到首位,其他照写,末尾标点符号变成问号即可。没有动词 be 的句子则要在句首加上一个助动词(do,does,did)再把紧跟在后面的动词变回原形,末尾标点符号变成问号即可。这三个助动词也要根据人称和时态来选择,其中“does”只用于一般现在时主语是第三人称单数的情况,而“did”只用于一般过去时,不论主语是什么人称和数,都用“did” 。一般疑问句有个重要的原则就是问和答要一致,即问句里的第一个单词(助动词)和简略答句里的这个词是一致的。4、特殊疑问句:以特殊疑问词(what , where , who , which , when , whose , why , how 等)开头引导的句子。此类句子应该问什么就答什么,不能用“yes 、no” 来回答。如:What is this? Its a computer.What does he do? Hes a doctor.Where are you going? Im going to Beijing.Who played football with you yesterday afternoon? Mike. Which season do you like best? Summer.When do you usually get up? I usually get up at 6:30.Whose s
