文檔簡介
時間名詞前所用介詞的速記歌年月周前要用in,日子前面卻不行。遇到幾號要用on,上午下午又是in。要說某日上下午,用on換in才能行。午夜黃昏須用at,黎明用它也不錯。at也用在明分前,說“差”可要用上to,說“過”只可使用past,多說多練牢牢記,莫讓歲月空蹉跎。下面就時間概念的介詞用法做一簡要介紹和比較。1.a(chǎn)t表示時間概念的某一個點。(在某時刻、時間、階段等)。at1:00(dawn,midnight,noon)在一點鐘(黎明、午夜、中午)theseareourchieftasksatthepresentstage.這些就是我們現(xiàn)階段的主要任務(wù)。2.on1)表示具體日期。theyarrivedinshanghaionmay25.他們在五月二十五日到達上海。注:(1)關(guān)于"在周末"的幾種表示法:at(on)theweekend在周末---特指at(on)weekends在周末---泛指overtheweekend在整個周末duringtheweekend在周末期間(2)在圣誕節(jié),應(yīng)說"atchristmas而不說"onchristmas2)在(剛……)的時候。onreachingthecityhecalleduphisparents.一到城里他就給父母打了一個電話。3.in1)表示"時段"、"時期",在多數(shù)情況下可以和dur-ing互換,前者強調(diào)對比,后者強調(diào)持續(xù)。in(during)1988(december,the20thcentury)在一九八八年(十二月、二十世紀)ireturnedtobeijinginthemiddleofjune.我是六月中回北京的。但如果表示"在某項活動的期間",則只能用during。duringmymilitaryservice(thetrip)在我服役期間(在旅行期間)2)表示以說話時間為基點的"(若干時間)以后",常用作將來時態(tài)謂語的時間狀語。如這時要表示"(若干時間)內(nèi)",常用within。比較:themeetingwillendin30minutes.(三十分鐘后)會議三十分鐘后結(jié)束。canyoufinishitwithin30minutes?(三十分鐘內(nèi))你能在三十分鐘之內(nèi)完成這件事嗎?但在過去時態(tài)中,in可用于表"在若干時間以內(nèi)",這時不要誤用during。thejobwasdoneduringaweek.(wrong)thejobwasdoneinaweek.(right)這工作在一星期內(nèi)就完成了。4.a(chǎn)fter表示"在(某具體時間)以后",注意不要和in的2)意混淆。aftersupper(8o’clock,thewar)晚飯(八點、戰(zhàn))后比較:hewillbebackintwohours.他將在兩個小時以后回來。hereturnedtohishometownafterthewar.戰(zhàn)后他回到了故鄉(xiāng)。5.for表示"(動作延續(xù))若干時間",有時可省略。istayedinlondon(for)twodaysonmywaytonewyork.在去紐約的途中,我在倫敦呆了兩天。6.since表示"自(某具體時間)以來",常用作完成時態(tài)謂語的時間狀語。sinceliberation(1980)自從解放(1980年)以來theyhavebeenclosefriendssincechildhood.他們從小就是好朋友。注:(1)sincethewar是指"自從戰(zhàn)爭結(jié)束以來",若指"自從戰(zhàn)爭開始以來",須說"sincethebeginningofthewar"。(2)不要將since與after混淆。比較:hehasworkedheresince1965.(指一段時間,強調(diào)時間段)自從1965年以來,他一直在這兒工作。hebegantoworkhereafter1965.(指一點時間,強調(diào)時間點)從1965年以后,他開始在這兒工作。7.by表示"到……的時候",其謂語時態(tài)的用法:動作動詞常用完成時態(tài);狀態(tài)動詞(be)常用一般時態(tài)。比較:bynoon,everybodyhad(willhave)arrivedthere.bynoon,everybodywere(willbe)there.到中午的時候,大家都(將)到那兒了。以上探討了介詞表示時間概念時的用法和比較,上述介詞除表示時間概念外還有其他的用法,英語學(xué)習(xí)者必須掌握其各種用法,才能靈活運用,提高自己的語言能力。
