英语中的句型转换属于较难的题型,对学生的英语综合才能有一定要求。除了必需把握基本的词汇外,还要对语法知识和句子语序有很好的把握。
一、一定句改否定句的办法:
1、在be动词后加not。
如:is not,are not,am not
在can,should,will等后加not。
如:can not,should not,will not;
3、上述都没有的,在动词前加助动词否定情势 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.
二、一定句改寻常疑问句的办法
1、把be动词(am,is,are)放在句首,第一个字母大写,剩下的照抄,句末用问号。
(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,第一个字母大写,剩下的照抄,句末用问号。
(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帮助,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、就寻常疑问句回复
寻常疑问句有两种回复,即:一定回复和否定回复。此中,一定回复用yes,否定回复用no。
语句排序为: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.
三、对划线局部发问
“就划线局部发问”是小学阶段英语学习的难点,但是一旦把握了纪律,就变得容易多了。小学英语对划线局部发问之答题口诀:
一代:用准确的疑问词代替划线局部。
二移:把疑问词移至句首
三倒:颠倒主谓语,但对主语或其定语发问时除外(some改成any,I改成you,my改成your),
四抄:照抄句子剩余局部。
★特别疑问词的确定要依据划线内容而定,在小学阶段常显现的有以下几种:
1.划线局部是“事或物”,特别疑问词用what
如:This is a book.---What is this?
I often play football on Saturdays.---What do you often do on Saturdays?
2.划线局部是“人”,特别疑问词用who
如:He is my brother.---Who is he?
3、划线局部是“地点”,特别疑问词用where
如:The box is on the desk.---Where is the box?
4、划线局部是“时间”,特别疑问词用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、划线局部是“年事”,特别疑问词用how old
如:I am twelve.---How old are you?
Myfatheristhirty-three.---Howoldisyourfather?
6、划线局部是“职业”,特别疑问词用what
如:Mike is a worker.---What is Mike?
7、划线局部是“颜色”,特别疑问词用what colour
如:My hat is blue.---What colour is your hat?
8.划线局部是“数目”,特别疑问词用how many或how much
如:I can see five kites.---How many kites can you see?

9.划线局部是“几多钱”,特别疑问词用how much

10.划线局部是“形貌词性物主代词或名词性物主代词”,特别疑问词用whose
如:That is my book.---Whose book is that?
The bag is yours.---Whose is the bag?
以下口诀要牢记:
