2、肯定句中如已有can,should,will等,则在其后加not。如:cannot,should not,will not;
3、肯定句中如没有上述Be动词或情态动词则先借
助动词do/does/did的否
定don’t/doesn’t/didn’
t。

改成any。

三、肯定句改特殊疑问句的方法——四步法
1、在一般疑问句的基础上,句首添加一个特殊疑
问词即可,特殊疑问词可根据划线部分确定(即:特殊疑问词+一般疑问句
构成特殊疑问句,但注意:Which, whose,how many除外,必须先在这些词后加名词,再加一般问句。另外,用特殊疑问词后划线部分不能再出现。)常用的疑问词有:what(什么),who(谁),whose (谁的),which(哪个),when(何时),where
(哪里),how(怎样),why(为何)等。

2. who意为“谁”,用来对“人”提问。
Who is behind the door? 谁在门后?
3. whose意为“谁的”,用来对物主代词及名词所有格进行提问。
Whose bag is this? 这个包是谁的?
4. which意为“哪个”,既可以对“人”提问,也可以对“物”提问。
which season do
you like best? 你最喜欢哪个季节?
5. when意为“什么时候”,对时间提问。对具体钟点提问用“what time”。
When did you arrive? 你什么时候到的?
What time does the first class begin? 几点
钟开始第一堂课?
6. why 意为“为什么”,对原因提问。
Why are you late? 你为什么迟到?

一起去?
7. where 意为“在哪里”,对地点提问。
where is lily? Lily在哪里?
