用英語：It is time to do something
我們可以把這個句子來拆開看
做某事是動詞詞組，有兩種說法，一個是to do sth，意思是去做某事，一個是doing sth，意思是做過某事，兩個用法時態不一樣。到做某事，就意味着還沒有做，要去做，用to do
時間，英語用time來表示
It's time to do something或者It's time for doing something.意思都是到做某事的時間了。
比如: It's time to go to bed.= It's time for going to bed.到上牀睡覺的時間了。
It's time to have breakfast.=It's time for having breakfast.到吃早餐的時間了。
It's time to read books.=It's time for reading books.到讀書的時間了。
