(1)直接表達(dá)法：鐘點+分鐘
It’s eleven o’clock.
It’s seven fifteen.
(2)間接表達(dá)法
●當(dāng)分鐘不超過30分鐘，用介詞past表示，結(jié)構(gòu)：分鐘+past +鐘點
five past nine = nine five (9:05)
fifteen past ten = ten fifteen = aquarter past ten (10:15)
thirty past two = two thirty =half past two (2:30)
●若分鐘超過30分鐘，用to來表示。差幾分到幾點，結(jié)構(gòu)：分鐘(60-分鐘)+ to + 鐘點(鐘點+1)
ten to ten = nine fifty (9:50)
fifteen to five = four forty-five= a quarter to five (4:45)
【注】① 表示整點時間，直接用基數(shù)詞表達(dá)，后邊可接o’clock (也可不加)。表達(dá)“幾點幾分”時，絕不能用o’clock。
② 表達(dá)“15分”或“45分”時，常用quarter(刻)。
