判断这句英语句子有没有语法错误Could you tell me which is the way to the mall?

有问题。这是一句宾语从句
应该是Can you tell me which the way is to the mall?

语法上没什么错的。

其实也没有什麼错的。
如果使用了逗号的话，在读句子的时候会更明确。
"Could you tell me, which is the way to the mall?"
如果想要一个日常的说法，这个比较适合：
"Could you tell me which way is the mall?"
在 'way' 的前面不需要用 'the'.

有，应该是：Could you tell me which the way to the mall is ?

语法上没什么问题
Can you tell me which is the way to ……?
你能告诉我哪条是去……的路吗?
不用从句就把which is去掉,直接Can you tell me the way to .

Could you tell me which the way (IS)to the mall?

有问题 可以是 Could you tell me which the way to the mall is？
Could you tell me how can I go to the mall?
