1. a, an的选择: 元音音素开头的单词用an,辅音音素开头的单词用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.

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:
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
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
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、人称代词主格及宾格
人称代词分为主格和宾格，主格和宾格区别：主格和宾格汉语意思相同，但位 置不同。
Eg:I(主格)\"我\"-- me (宾格)\"我\"
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。 Eg :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(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 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.
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.
He does not (doesn't) work in a hospital. There are not (aren't) four fans in our classroom. ☆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. 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. ☆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. 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.
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.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？ ☆注意☆ 小结:
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)
