How to ask questions using CAN?
Almost any yes-no question can be formed simply by placing 吗 after a statement.

statement: You can pour me some water. (你可以给我倒些水。)
question: Can you pour me some water? (你可以给我倒些水吗？)
statement: You can go running tomorrow with me. (明天你可以和我去跑步。)
question: Can you go running tomorrow with me? (明天你可以和我去跑步吗？)

Also, when asking someone to do something, you can use the pattern &quot;Do something 好吗？&quot;

给我倒些水好吗？
明天和我去跑步好吗？

Here 好吗 can also be 行吗/可以吗
