形容词比拟级

当我们须要对事物作出比拟时,须要用到比拟级。

比拟级的句子构造凡是是:

什么 + 动词be (am , is , are ) + 形容词比拟级 + than(比)+ 什么 ,如:

①I’m taller and heavier than you. (我比你更高和更重.)

②An elephant is bigger than a tiger. (一只年夜象比一只山君更年夜.)

形容词的比拟级是在形容词的基本上变更而来的,它的变更规矩是:

① 一般的直接在词尾加er ,如 tall – taller , strong – stronger ,

睁开全文

② 以e结尾的,直接加r ,如 fine – finer ,

③ 以子音字母加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

留意:

比拟的两者应当是互相对应的可比拟的工具。

典范过错:My hair is longer than you.(我的头发比你更长.)

比拟的两者是我的头发,你(全部人),那么比拟的对象就没有可比性。

应当改为:My hair is longer than yours. 或My hair is longer than your hair.

动词曩昔式

动词的曩昔式的组成规矩有:

A.规矩动词

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 以子音字母加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 (留意play,stay不是子音字母加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.不规矩动词(此类词并无规矩,须熟记)小学阶段要记住以下动词的本相和曩昔式: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

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,要先往e再加ing ,如having , writing

③ 双写最后一个字母的(此类动词少少)有:running , swimming , sitting , getting

人称代词主格及宾格

人称代词分为主格和宾格,主格和宾格差别:主格和宾格汉语意思雷同,但地位分歧。

Eg:I(主格)”我”– me (宾格)”我”

主格在陈说句中凡是放句首,宾格凡是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

句型专项回类

1.确定句:是指用确定的语气来陈说的句子

如:I’m a student.

She is a doctor.

He works in a hospital.

There are four fans in our classroom.

2.否认句:含有否认词或表现否认意义词的句子

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.

小结:

否认句重要是在确定句的基本上加上了否认词 “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 一般都离开写.没有动词be的句子则要先在重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路如”don’t , doesn’t , didn’t ).这三个助动词要依据人称和时态来选择,此中”does”只用于一般此刻时主语是第三人称单数的情形,而”did”只用于一般曩昔时,非论主语是什么人称和数,都用”did” .

3.一般疑问句:是指讯问事实的句子,此类句子必需用”yes”,或”no”往返答

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.

小结:

一般疑问句是在确定句的基本上,

①把动词be调到首位,其他照写,末尾标点符号酿成问号即可。

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本相,末尾标点符号酿成问号即可。

这三个助动词也要依据人称和时态来选择,此中”does”只用于一般此刻时主语是第三人称单数的情形,而”did”只用于一般曩昔时,非论主语是什么人称和数,都用”did” 。一般疑问句有个主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)和简单答句里的这个词是一致的。

4.特别疑问句:以特别疑问词(what , where , who , which , when , whose , why , how等)开首领导的句子。此类句子应当问什么就答什么,不克不及用”yes ,no”往返答。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?

小结:

此中how又可以和其他一些形容词连用构成特别疑问词组用来提问,如: how many(几多(数目)), how much(几多(钱)),how tall(多高),how long(多长), how big(多年夜), how heavy(多重)

例句:How many pencils do you have ?

How many girls can you see ?

how many 用来提问可数名词的数目,重要有以下三种搭配,:

How many + 名词复数 + do you have 你有几多……

How many + 名词复数 + can you see 你能看见几多……

How many + 名词复数 + are there… 有几多……

完整,缩略情势

1.简缩情势的变法:把倒数第二个字母,凡是是元音字母酿成’ 但are除外,are要把a打成’ 。Eg:he is=he’s they are=they’re

2.简缩情势和完整情势的汉语意思雷同。

3.把完整情势酿成简缩情势时,必定要留意第一个字母的巨细变更。Eg:What is =What’s

4.记住一个特别变更;let’s =let us 让我们(不要把’ 酿成i)

5.记住:this is 没有简缩情势this’s(过错)

6.常见的缩略情势:

I’m=I am

he’s=he is

she’s=she is

they’re=they

you’re=you are

there’s=there is

they’re=they are

can’t=can not

don’t=do not

doesn’t=does not

isn’t=is not

aren’t=are not

let’s=let us

won’t=will not

I’ll=I will

wasn’t=was not
