先请看试题:

---Do you know the exact date of his death?


---No. but I remember he died _____ a cold Friday night.


A. in B. by C. on D. at


【易错选项】选D


【易错原因】at night意为“在晚上”,但表示在具体某一天的晚上时用介词on。


【正确答案】 C


【试题解析】in后多接月份、季节、年代等的名词;by“在旁边”;at后接具体时刻。on可用于表示具体的某一天,故选C。

at通常指确切的某个时刻,如at six o'clock,in通常表示一天的某一部分,如in the morning,on则具体说明哪一天的上午或下午,如on Monday morning,on a summer's day。

on the night of 10 January/January 10

在1月10日晚上


Let's go out on Saturday night .

我们星期六晚上出去吧。

We got the news on the morning of the wedding.

我们在举行婚礼的那天上午得到这个消息。

On Sunday morning Bill was woken by the telephone

星期天早晨,比尔被电话铃声吵醒了。

在谈论节日时,at通常指整个的节日,不只指一天,如at Easter 在复活节, on可具体指节日的某一天,如on Easter Monday 在复活节后的星期一,在谈论月份、季节、年份或世纪时,通常用介词in,如in the eighteenth century 在18世纪。

in January


in winterin 1999;in the morning/ afternoon /evening. in the daytime on Monday, on Sunday afternoon, on July 1st, 2011


注:

② on“在具体某一天” “当某时”,动名词, arrival,death前;early,late位句先

②,用in一般“上”“下”“晚”;on用于天,in用于月、季、年

③ 限定三时in要变。

④ at是个时间点,“工作”“时刻”与“圣诞”

⑤ at noon(night),in the day,习惯用语记心间。

特别强调:①on表示在具体某一天及具体某一天的上午、下午和晚上。 例 On mother's Day, we should send flowers to our mother. 母亲节,我们应该送花给我们的母亲。 On my arrival home,I found he had gone already.当我到家时,我发现他已经走了。

② 当early,late用于句首修饰介词短语时,尽管表示具体某一天的上午、下午、晚上,都要用in,泛指一般的上、下午,晚上也用in 。 例 Early in the morning of National Day,I got up to catch the first bus to the zoo. 国庆节一清早,我便起床去赶到动物园的第一班公共汽车。
