306　o'clock和hour

1　o'clock 是of clock的縮寫，表示“……時(shí)……點(diǎn)鐘”，指鐘表上的某一時(shí)刻，時(shí)間的某一點(diǎn)，用于正點(diǎn)，“幾點(diǎn)幾分”不可用o'clock。

It's six o'clock in the morning. 時(shí)間是早上6點(diǎn)鐘。

A： What time is it? 幾點(diǎn)了 ?

B： It's ten (o'clock). 10點(diǎn)了 。（o'clock也可省略 ）

It's ten past five.（正）5點(diǎn)10分 。

It's ten past five o'clock .（誤）

2　“在幾點(diǎn)”要用at ，如：“在4點(diǎn)鐘”是at four o'clock，“在9點(diǎn)鐘”是at nine o'clock。

She came at three o'clock and left at seven o'clock . 她3點(diǎn)鐘來(lái)的，7點(diǎn)鐘離開(kāi)的。

3　hour 意為“小時(shí)”，是指時(shí)間的長(zhǎng)度單位；“1個(gè)小時(shí)，幾個(gè)小時(shí)”要用hour ，為one hour， several hours，不可用o'clock。

I saw him an hour ago. 我在一個(gè)小時(shí)前見(jiàn)到他的。
