a 是正确的
at,in,on在表示时间上的区别
1.at指时间表示:
(1)时间的一点、时刻等.如:
They came home at sunrise (at noon,at midnight,at ten o’clock,at daybreak,at dawn).
(2)较短暂的一段时间.可指某个节日或被认为是一年中标志大事的日子.如:
He went home at Christmas (at New Year,at the Spring Festival,at night).
2.in指时间表示:
(1)在某个较长的时间(如世纪、朝代、年、月、季节以及泛指的上午、下午或傍晚等)内.如:
in 2004,in March,in spring,in the morning,in the evening,etc
(2)在一段时间之后.一般情况下,用于将来时,谓语动词为瞬间动词,意为“在……以后”.如:
He will arrive in two hours.
谓语动词为延续性动词时,in意为“在……以内”.如:
These products will be produced in a month.
注意:after用于将来时间也指一段时间之后,但其后的时间是“一点”,而不是“一段”.如:
He will arrive after two o’clock.
3.on指时间表示:
(1)具体的时日和一个特定的时间,如某日、某节日、星期几等.如:
On Christmas Day(On May 4th),there will be a celebration.
(2)在某个特定的早晨、下午或晚上.如:
He arrived at 10 o’clock on the night of the 5th.
(3)准时,按时.如:
If the train should be on time,I should reach home before dark.
