口语中Good for you的用法

问题描述

—Mummy, I've finished all the work you assigned me.

—_______.

A. You are good

B. It's good for you

C. It's good to you

D. Good for you

答案为 D，请问为什么？B 为何不行？ 

老师答疑

黎老师：

Good for you ! （口）干得好！真棒！

You won the race! Good for you! 你赛跑赢了！真棒！(《外研社英汉多功能词典》)

所以，根据对话的语境，D(Good for you)应该是最佳答案。如果选择 it's good for you，则 it 指代不明确。

曾老师：

同意黎老师的分析，再补充两例：

She passed the exam? Good for her! 她考试及格了? 真行! 《牛津高阶英汉双解词典》

"He has a girl now, who he lives with." — "Good for him." “他现在有女朋友了，他们住在一起。” ——“他可真行啊。” 《柯林斯高级英语学习词典》
