小学英语学习更多的是语句结构以及动名词的使用,下面就是小编给大家带来的小升初英语知识点复习资料,希望能帮助到大家!
一: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
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:
…… + 动词be (am , is , are ) + 形容词比较级 + than(比)+ …… ,
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,它的变化规则是:
① 一般的直接在词尾加er ,如 tall - taller , strong - stronger ,
② 以e结尾的,直接加r ,如 fine – finer ,
③ 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
☆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.
三:动词过去式 动词的过去式的构成规则有:
A、规则动词
① 一般直接在动词的后面加ed:如 worked , learned , cleaned , visited
② 以e结尾的动词直接加d:如 lived , danced , used
③ 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 stopped
B、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 动词的ing形式的构成规则:
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
五:人称和数
六:句型专项
1、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.
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:I’m not a student.
She is not (isn’t) a doctor. He does not (doesn’t) work in a hospital.
There are not (aren’t) four fans in our classroom.
He will not (won’t) eat lunch at 12:00.
I did not (didn’t) 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“isn’t,aren’t”,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“don’t , doesn’t , didn’t )。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。
☆注意 小结:一般疑问句是在肯定句的基础上,
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。
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。
☆小结:how many 用来提问可数名词的数量,主要有以上三种句式搭配,
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……?
七:完全、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
总结:通常情况下,'m即am,'s即is(但 let’s=let us), 're即are ,n't即not (但can’t=can not)
八:名词复数规则
1.一般情况下,直接加-s, 如:book-books, bag-bags, cat-cats, bed-beds.
2.以s. x. sh. ch结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches.
3.以“辅音字母+y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries.
4.以“f或fe”结尾,变f或fe为v, 再加-es,如:knife-knives.
5.不规则名词复数:
man-men, woman-women, policeman-policemen, policewoman-policewomen, mouse-mice child-children foot-feet,. tooth-teeth fish-fish, people-people, Chinese-Chinese, Japanese-Japanese
