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

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：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.

☆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” 。
