贤知助手学校为您带来中考数...
小学英语中的句型转换属于较难的题型,
对孩子的英语综合能力有一定要求。
除了必须掌握基础的词汇外,
还要对语法知识和句子语序有很好的掌握。
很多孩子在这种题型上失分比较严重,
其实是他们没有掌握好方法。
小学英语的句型转换就只有那几种类型,
只要掌握了方法,就不怕不会做啦!
肯定句改否定句的方法
1、 在be动词后加not。如:is not , are not , am not
2、 在can,should, will等后加not。如:cannot, should not, will not;
3、 上述都没有的,在动词前加助动词否定形式don’t/doesn’t/didn’t。
4、 some 改成any。
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.
肯定句改一般疑问句的方法
1、 把be动词放在句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句点改成问号。
2、 把can,shall, will等放到句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句点改成问号。
3、 上述都没有的,在句首请助动词Do/Does/Did帮忙,剩下的照抄,(some 改成any,I改成you,my改成your,)句点改成问号。
注意:句首的第一个字母要大写,句尾标点应为“?”。
如:
I am in Class 6. →Are you in Class 6?
You are from America. →Are you from America?
It is an orange. →Is it an orange?
4、 就一般疑问句回答
一般疑问句有两种回答,即:肯定回答和否定回答。其中,肯定回答用yes,否定回答用no。 语句顺序为:Yes + 主语 + am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/ isn’t/ aren’t
如:
—Are you an English teacher?→Yes, I am. /No, I am not.
—Is that a bird? →Yes, it is./ No, it isn’t.
对划线部分提问
“就划线部分提问”是小学阶段英语学习的难点,但是一旦掌握了规律,就变得容易多了。 小学英语对划线部分提问之答题口诀 :
一代:用正确的疑问词代替划线部分
二移:把疑问词移至句首
三倒:颠倒主谓语,但对主语或其定语提问时除外(some 改成any,I改成you,my改成your)
四抄:照抄句子剩余部分
特殊疑问词的确定要根据划线内容而定,在小学阶段常出现的有以下几种:
①划线部分是“事或物”,特殊疑问词用what
如: This is a book.---What is this?
I often play football on Saturdays .---What do 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 the desk.---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 seven twenty . ---What time is it ?
I usually get up at six . --- When do you usually get up?
⑤划线部分是“年龄”,特殊疑问词用how old
如:I am twelve . ---How old are you?
My father is thirty-three . ---How old is your 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. ---How much 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 ?
