小升初英语必背知识点1
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：
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、动词过去式详解
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、动词现在分词详解
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：
人称代词物主代词
主格宾格
第一
人称单数I(我) me my(我的)
复数we(我们) us our(我们的)
第二
人称单数you(你) you your(你的)
复数you(你们) you your(你们的)
第三
人称单数he(他) him his(他的)
she(她) her her(她的)
it(它) it its(它的)
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：
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.
☆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。
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.
Are there four fans in our classroom? Yes, there are. / No, there aren’t.
Are you going to buy a comic book tonight? Yes, I am. / No, I am not. (Yes, we are. / No, we aren’t.)
Will he eat lunch at 12:00? Yes, I will. / No, I will not(won’t).
Are they swimming? Yes, they are. / No, they aren’t.
Did you watch TV yesterday evening? Yes, I did. / No, I didn’t.
☆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。
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。
