( )3.—Can I wear my new dress today,Mum?
— It's a little cold outside.

A.No,you can't.
B.Yes,you can.
C.Yes,I can.

【解析】：这是一道英语选择题，考查的是日常交际用语以及情景对话的理解。题目中的对话是关于孩子询问母亲今天是否可以穿新裙子，而母亲则根据天气情况（外面有点冷）来给出回答。我们需要根据对话内容，选择最符合语境的回答。
A选项“No, you can't.”表示“不，你不能。”，这是一个否定回答，符合母亲因为天气冷而拒绝孩子穿新裙子的情境。
B选项“Yes, you can.”表示“是的，你可以。”，这是一个肯定回答，与母亲提到的天气冷相矛盾。
C选项“Yes, I can.”表示“是的，我能。”，这个回答的主语是“I”，与问题中的“you”不符，因此也不正确。
【答案】：A
