    優(yōu)質(zhì)解答
    1. at指時(shí)間表示:
    (1)時(shí)間的一點(diǎn)、時(shí)刻等.如:
    They came home at sunrise (at noon, at midnight, at ten o’clock, at daybreak, at dawn).
    (2)較短暫的一段時(shí)間.可指某個(gè)節(jié)日或被認(rèn)為是一年中標(biāo)志大事的日子.如:
    He went home at Christmas (at New Year, at the Spring Festival, at night).
    2. in指時(shí)間表示:
    (1)在某個(gè)較長(zhǎng)的時(shí)間(如世紀(jì)、朝代、年、月、季節(jié)以及泛指的上午、下午或傍晚等)內(nèi).如:
    in 2004, in March, in spring, in the morning, in the evening, etc
    (2)在一段時(shí)間之后.一般情況下,用于將來(lái)時(shí),謂語(yǔ)動(dòng)詞為瞬間動(dòng)詞,意為“在……以后”.如:
    He will arrive in two hours.
    謂語(yǔ)動(dòng)詞為延續(xù)性動(dòng)詞時(shí),in意為“在……以內(nèi)”.如:
    These products will be produced in a month.
    注意:after用于將來(lái)時(shí)間也指一段時(shí)間之后,但其后的時(shí)間是“一點(diǎn)”,而不是“一段”.如:
    He will arrive after two o’clock.
    3. on指時(shí)間表示:
    (1)具體的時(shí)日和一個(gè)特定的時(shí)間,如某日、某節(jié)日、星期幾等.如:
    On Christmas Day(On May 4th), there will be a celebration.
    (2)在某個(gè)特定的早晨、下午或晚上.如:
    He arrived at 10 o’clock on the night of the 5th.
    (3)準(zhǔn)時(shí),按時(shí).如:
    If the train should be on time, I should reach home before dark.
    at (on) the weekend (在周末——特指)
    at (on) weekends (在周末——泛指)
    over the weekend (在整個(gè)周末)
    during the weekend (在周末期間).
    在圣誕節(jié),應(yīng)說(shuō)"at Christmas", 而不說(shuō)"on Christmas".
