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

2、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+amnot/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。
