你好，同学
Can you buy these things at shopping malls?
No, we can't.
翻译：你们能在购物中心买到这些东西吗？
不，我们不能。
解析：
一般疑问句是疑问句的一种。它是指用yes（是）或no（否）来回答的句子。其结构是：
系动词be/助动词/情态动词＋主语＋其他成分?
通常回答为：
肯定：Yes，+主语+提问的助动词.
否定：No，+主语+提问的助动词+not.
如:
Are you from Japan﹖
Yes I am． ／ No I'm not．
Is her sister doing her homework now﹖
Yes she is． ／ No she isn't．
Does he work in a bank﹖
Yes he does． ／ No he doesn't．
Do you live near your school﹖
Yes I do． ／ No I don't．
Can you speak French﹖
Yes I can． ／ No I can't．
May I go home now﹖
Yes you may． ／ No you mustn't．
注意：
1．将陈述句变为一般疑问句时，如句中有be 动词（am is are …）时，可直接将它们提至主语前。如主语为第一人称，应将其改为第二人称。如：
I'm in Class 2Grade 1． →
Are you in Class 2Grade 1﹖
We're watching TV． →
Are you watching TV﹖
2．陈述句中有情态动词（can may must …）时，也可直接将它们提至主语前，即可成为一般疑问句。如：
He can swim now． →
Can he swim now﹖
The children may come with us． → May the children come with us﹖
3．陈述句中只有一个实义动词作谓语且其时态为一般现在时，变为一般疑问句时要在句首加do或does 主语后的实义动词用原形。如：
I like these animals． →
Do you like these animals﹖
She wants to go to the movies． → Does she want to go to the movies﹖
4．一般疑问句一般读升调(↑) 6. 一般疑问句的第一单词总是虚词,读的时候要读轻声。
5．一般疑问句有时不用yes或 no 回答。如：
Are they in town now﹖
I think so.
May I sit here﹖
Certainly．
Does he like soccer﹖
Sorry I don't know．
