小結(jié)：
介詞用法簡(jiǎn)介Saying when things happened
在表示時(shí)間時(shí)，我們有三個(gè)介詞可以選擇：in，at和on。
介詞in的用法：
介詞in 用在年、月份、季節(jié)、一天中某個(gè)部分以及年代的前面。
比如，
in 1999 在1999年
in August 在八月份
in winter 在冬季
in the afternoon, in the evening, in the morning 在下午/在晚上/在早上
in the 1950s 在50年代
in the 21st century 在21世紀(jì)
介詞on的用法：
介詞on用在星期幾、幾號(hào)等具體的日期前。比如：
on Thursday 在星期四
on 19 January 在1月19日
on Monday morning (請(qǐng)比較：in the morning)
on a cold night (請(qǐng)比較：at night)
但是當(dāng)星期幾的前面有指示性的詞比如：this，next和last來(lái)修飾時(shí)，就不用介詞on。
介詞at的用法：
介詞at 用在點(diǎn)鐘、宗教節(jié)日和一些固定的詞組中。比如：
at 5.30 p.m. 在下午5.30分
at Easter 在復(fù)活節(jié)
at the end of the war 在戰(zhàn)爭(zhēng)的末期
at the beginning of the term 在這學(xué)期開(kāi)始
但是當(dāng)宗教節(jié)日中帶有day這個(gè)詞時(shí)，前面的介詞用on 。
at Christmas on Christmas Day
at/on the weekend 在周末
