英语中的句型转换属于较难的题型,对学生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。
一、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
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.
二、肯定句改一般疑问句的方法
1、把be动词(am,is,are)放在句首,*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,*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*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.
三、对划线部分提问
"就划线部分提问"是*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。*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*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
