It's up to... 由……来决定
用法透视
"to"后面接代词宾格或名词，表示“由……来做决定；取决于……；是……的职责”。
支持范例
1. Do you want to eat a Western or Chinese meal? It's up to you.
吃西餐还是中餐？由你来决定。
2. It's up to us to help those in need.

会话记忆
A: I'm looking forward to our son's graduation this weekend.
我盼着这个周末儿子毕业呢。
B: Yes. So am I. But what will he do after graduation? He really needs to go to college.
我也是。不过他毕业后做什么呢？他需要上大学。
A: Well, dear, we can't force him to go to college. It's up to him.
可是亲爱的，我们不能强迫他上大学啊，这得由他决定。
B: I know that but he has to learn to be independent. He can't just keep living at home.
我知道，但他得学会自立，他不能老待在家里。
多说两句：
"It's up to"后面通常跟的是某人。还有一个短语也表示“取决于……；由……决定”，即"depend on"，但这个短语后面跟的通常是某事物。例如：
It all depend on whether she like the boss or not.
一切都取决于她喜欢还是不喜欢这个老板。
But that all depend on the specific circumstances.
不过，那要看具体情况而定。
