五年级英语课外辅导第六课

三种句型变换详讲：（一般现在时）

肯定句变一般疑问句方法：两种情况：

1、若句子中有be动词：则把句子中的be动词提到句首（be动词包括：am/ is /are）格式：be动词提到句首例如：I am a student.→Are you a student？She is a teacher.→Is she a teacher?They are good friends.→ Are they good friends?

2、若句子中没有be动词：则B:如果句子中没有be动词和情态动词，就要在句首加上助动词帮助其变成一般疑问句。（情态动词包括do和does）格式： Do/Does+主语+动词原形+宾语？主语是第一、二人称和复数人称时在句首加上Do；主语是第三人称单数形式时加Does。加上Does之后，原来句子中的三单形式要还原。人称：第一人称：单数：I 复数：we第二人称：单数：you 复数：you第三人称：单数：she、he、it以及人名例如：You have a friend. → Do you have a friend?She likes apples. → Does she like apples?(你可以看到这个变换时does后面的动词：like变成原形了，不能加S）Amy does her homework at home.Does Amy do her homework at home?

肯定句变否定句方法：两种情况：1、句子中 若有be动词：在be动词后加not。如：is not ， are not ， am not2、 句子中若没有be动词，在动词前加助动词否定形式don’t/doesn’t/didn’t。格式：主语+ doesn’t +动词原形+宾语.如： I am a girl. → I am not a girl.You are a student. →You are not a student.→You aren’t a student.This is Tom’s bag, → This is not Tom’s bag.→ This isn’t Tom’s bag.

She likes apples. →she doesn’tlike apples.

肯定句变特殊疑问句方法：两种情况：

（这一种主要是搞清楚一般出题时是就划线部分进行提问，重点看它要问什么，这时就要注意特殊疑问词的选择）

同样：看是否有be动词：有：特殊疑问词+be动词+主语+动词原形？ 如果无：特殊疑问词+does+主语+动词原形？

另外要根据问的什么来确定疑问词：

1、划线部分是“事或物”，特殊疑问词用what

如: This is abook.---What is this?

I often play football on Saturdays .---Whatdo you often do on Saturdays ?

2、划线部分是“人”，特殊疑问词用who

如:He is my brother.---Who is he ?

3、划线部分是“地点”，特殊疑问词用where

如:The box is on thedesk.---Where is the box ?

4、划线部分是“时间”，特殊疑问词用what time或when

如:It's seventwenty . ---What time is it ?

I usually get up at six . --- When do youusually get up?

5、划线部分是“年龄”，特殊疑问词用how old

如:I am twelve . ---Howold are you?

My father is thirty-three . ---How old isyour father ?

6、划线部分是“职业”，特殊疑问词用what

如:Mike is a worker.---What is Mike ?

7、划线部分是“颜色”，特殊疑问词用what colour

如: My hat is blue .---What colour is your hat？

8. 划线部分是“数量”，特殊疑问词用how many或how much

如:I can see five kites.---How many kites can you see ?

There is some milk in the glass. ---Howmuch milk is there in the glass ?

9、划线部分是“多少钱”，特殊疑问词用how much

如:This pen is nine yuan. ---How much is this pen ?

10、划线部分是“形容词性物主代词或名词性物主代词”，特殊疑问词用whose

如:That is my book .---Whose book is that ? The bag is yours. ---Whose is the bag ?

【名称】第三人称单数【含义及用法】在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。一般情况：直接加+S，如：play-plays以s、x、sh、ch、和o结尾：+es,如：go-goes以辅音字母加y结尾：变y为i+es,如：study-studies特殊情况：不规则的，如：have-has

总结：

一、陈述句变一般疑问句：

先看有无被动词（am,is,are,was,were),情态动词（can,may,will,would,..),有的话把它们直接提前，其他的句子成份上面照抄到下面，若没有看句中动词所用的时态（过去时借助did,一般现在时原形借助do,单三用does)借助适当的助动词；

如：1、I am a student. （有被动词am,所以不用借，但am要换成are, I 要换成you）

我是学生。变成问句便是：你是学生吗？ Are you a student?

2、He can climb the tree.（有情态动词can,直接提前，其他照抄） Can he climb the tree ?

3、She cleaned her house . （既无被动词，也无情态动词，所以借用助动词）（cleaned是过去时，所以借助did (前有do,does ,did,后面动词用原形））

Did she clean her house.

二、陈述句变特殊疑问句：

在变一般疑问句的基础上加特殊疑问词，其他都一样。特殊疑问词的选择主要看画线部分，画的是什么有什么词代替，如数字用how many,钱用how much ,什么用what,时间用when,地点用where.问原因用why...

如：The book is ten yuan.（在ten yuan处画线）价钱用How much,How much is the book?

三、陈述句变否定句：

先找有无被be动词、情态动词，有直接在后面加not,若没有，借用助动词，再加not.

如：He is a good student. 有is 直接加not . He is not agood student.

Does she come from China? 直接在助动词后加not . Does not she come from China?

where do you go? 直接在助动词后加not Where do not you go?

至于相关疑问句回答如下：

Are you a student ? 肯定：Yes , I am. 否定：No,I am not.

Does he have four apples? 肯定Yes,he does. 否定：No,he doesnot.

Why are you late ? Because I...(和提问时一样，问啥答啥）
