It's up to... 由……來決定

用法透視

"to"后面接代詞賓格或名詞，表示“由……來做決定；取決于……；是……的職責”。

支持范例

1. Do you want to eat a Western or Chinese meal? It's up to you.
吃西餐還是中餐？由你來決定。

2. It's up to us to help those in need.
我們有責任幫助那些有困難的人。

3. It's not up to you to tell me how to do my job.
用不著你來告訴我怎樣做我自己的工作。

會話記憶

A: I'm looking forward to our son's graduation this weekend.
我盼著這個周末兒子畢業呢。

B: Yes. So am I. But what will he do after graduation? He really needs to go to college.
我也是。不過他畢業后做什么呢？他需要上大學。

A: Well, dear, we can't force him to go to college. It's up to him.
可是親愛的，我們不能強迫他上大學啊，這得由他決定。

B: I know that but he has to learn to be independent. He can't just keep living at home.
我知道，但他得學會自立，他不能老待在家里。

多說兩句：

"It's up to"后面通常跟的是某人。還有一個短語也表示“取決于……；由……決定”，即"depend on"，但這個短語后面跟的通常是某事物。例如：

It all depend on whether she like the boss or not.
一切都取決于她喜歡還是不喜歡這個老板。
But that all depend on the specific circumstances.
不過，那要看具體情況而定。
