小升初英语必背知识点

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。
