资源简介 中考英语复习:七年级英语上册易错知识点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:表示某人有某物品。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) 形容词比较级形容词比较级当我们需要对事物作出比较时,需要用到比较级。句子结构A + 动词be (am, is, are ) + 形容词比较级 + than(比) + B 例如:I'm 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。下面跟大家讲述一下变化规则。变化规则① 一般的直接在词尾加er,如 tall - taller,strong - stronger② 以e结尾的,直接加r,如 fine – finer③ 以辅音字母加y结尾的,先改y为i再加er,如funny - funnier ④ 双写最后的字母再加er,如big – bigger,thin – thinner,hot – hotter 细节提醒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。分析: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. 动词过去式动词过去式构成结构A:规则动词① 一般直接在动词的后面加ed:如 worked,learned,cleaned,visited② 以e结尾的动词直接加d:如 lived,danced,used③ 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) ④ 双写最后一个字母(此类动词较少):如 stoppedB、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 - gotread - read ,fly - flew , am/is - was , are - were , say - said , leave - left , swim - swam ,tell - tolddraw - drew ,come - came , lose - lost , find - found , drink - drank , hurt - hurt ,feel - felt 动词的ing形式的构成规则构成规则① 一般的直接在后面加上ing , 如doing , going , working , singing , eating ② 以e 结尾的动词,要先去e再加ing ,如having , writing ③ 双写最后一个字母的(此类动词极少)有:running , swimming , sitting , getting 英语人称代词主格及宾格人称代词分类人称代词分为主格和宾格。例:I(主格)"我"-- me (宾格)"我"主格和宾格的区别主格和宾格汉语意思相同,但位置不同。主格在陈述句中通常放句首,宾格通常放在动词后或介词后,也就是说宾格不放在句首。例:I have a new car.( I 主格)Excuse me (me 宾格)I ask him to go (him 宾格)They sit in front of me (me 宾格)主格与宾格主格(8个):I 我 you你 he他she她 it它 we我们 you你们they他(她、它)们宾格(8个):me我 you你him他 her她 it它 us我们 you你们 them他(她、它)们01句型专项归类肯定句是指用肯定的语气来陈述的句子。如:I'm a student.She is a doctor. He works in a hospital. There are four fans in our classroom.02否定句含有否定词或表示否定意义词的句子。如:I'm not a student.He does not (doesn't) work in a hospital. There are not (aren't) four fans in our classroom. 细节提醒1 . 否定句主要是在肯定句的基础上加上了否定词 "not"。2 .有动词be的句子则"not"加在be后面,可缩写成"isn't,aren't",但am not 一般都分开写。3 . 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",也可以把它们缩写在一起如"don't,doesn't,didn't )。4 . do,does,did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"。03一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, I'm not.Is she a doctor?Yes, she is. \ No, she isn't.Does he work in a hospital ?\Yes, he does. / No, he doesn't.Did you watch TV yesterday evening \ Yes, I did. / No, I didn't. 细节提醒 一般疑问句是在肯定句的基础上,要注意:1 . 把动词be调到首位,其他照写,末尾标点符号变成问号即可。2 . 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。3 . 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"。4 . 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。04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?Where are you going?Who played football with you yesterday afternoon? When do you usually get up?Why do you like spring best ?How are you?细节提醒1 . 其中how又可以和其他一些形容词连用组成特殊疑问词组用来提问,如:how many(多少(数量)),how much(多少(钱)),how tall(多高),how long(多长),how big(多大),how heavy(多重) 例句:How many pencils do you have ?How many girls can you see ?2 . how many 用来提问可数名词的数量,主要有以下三种搭配:How many + 名词复数 + do you have 你有多少…… How many + 名词复数 + can you see 你能看见多少…… How many + 名词复数 + are there… 有多少…… 完全式、缩略式1 . 简缩形式的变法:把倒数第二个字母,通常是元音字母变成' ,但are除外,are要把a打成' 。Eg:he is=he's they are=they're2 . 简缩形式和完全形式的汉语意思相同。3 . 把完全形式变成简缩形式时,一定要注意第一个字母的大小变化。Eg:What is =What's4 . 记住一个特殊变化;let's =let us 让我们(不要把' 变成i) 5 . 记住:this is 没有简缩形式,this's(错误)6 . 常见的缩略形式:I'm=I am he's=he is she's=she is they're=they are you're=you are there's=there is they're=they are can't=can not don't=do not doesn't=does not isn't=is not aren't=are not let's=let us won't=will not I'll=I will wasn't=was not 展开更多...... 收起↑ 资源预览
