ought to與should的用法區(qū)別

1. ought to 和 should 都表示義務，意思為：應該，本該。但 ought to 強調(diào)道義、法律所規(guī)定的職責；而 should 一般是表示說話者的一種主觀看法。如：

We ought to respect our teachers and parents. 我們應該尊敬老師和父母親。

We should work hard. 我們應該努力工作。

2. ought to 和 should 接動詞的完成時，表示該做的事而未做，常含有對對方的責備。如：

You ought to / should have finished your work yesterday. 你本應該在昨天就把工作完成了。

I should have visited you if I had known your address. 要是我知道你的地址，我早該來拜訪你了。
