一.小学英语单数变复数的规律：
1、多数情况下在名词后面加S，
2、以s,x,sh,ch为结尾的词在词尾加es,
3、以f,fe为结尾的词去掉f或fe加ves，
4、以辅音加y结尾的词，变y 为ies
5、以元音加y结尾的词，直接加s
6、不规则变化
eg：man-men，woman-women，policeman-policemen，Policewoman-policewomen

二.小学英语名词所有格语法
1、 变法：在人名后面加's
记住：'s要译成"的"eg:Lucy(名词所有格)Lucy's
2、 如果是2个或2个以上人的名词所有格要在最后一个人名加's
eg：Lily and Lucy (名词所有格)Lily and Lucy'S
Lily Lucy and Julia (名词所有格) Lily Lucy and Julia's
3、 以s结尾的名词复数所有格在后面加’，eg:students'
三.小学英语一般疑问句
1、一般疑问句最基本的变法：be 提前 用问号 读升调
2、my变成your our变成your I am / We are 变Are you I can 变Can you
3、注意人名不论放在什么位置都要大写 Tom is a student。Is Tom a student?
4、一般疑问句翻译成汉语都有"吗"?
1)This is my English teather. Is this your Englishteather?
2)It is our school. Is it your school?
3)We are students. Are you students?
4)I can sing. Can you sing?
四.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：
什么 + 动词be (am , is , are ) + 形容词比较级 + than(比)+ 什么，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：比较的两者应该是互相对应的可比较的东西。
五.语法易错点
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.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)
六、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
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
