1、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.
2、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.
3、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
