表示時間的介詞
運用
英語中表示時間的詞語主要分為以下幾類:時間點、時間段、動作發生的頻度、動作或事件發生的先後。一般可用單個副詞來表示,也可以用帶有介詞in, at, on和for的短語來表示。此外,一些不帶介詞的短語也可以用來表示動作(事件)發生(狀態持續)的時間。
時間介詞用法
一、單個副詞表示時間
1. 表示動作(事件)發生的時間
這類副詞常見的有:ago, before, lately, later (on), now, recently, then, today, tomorrow, tonight, yesterday等。例如:
1)It’s beginning to rain now! (時間點)現在開始下雨了！
2)I haven’t seen her recently. (時間段) 最近我沒見到她。
3)Will you be free tonight? (時間段) 你今晚有空嗎？
4)See you later. (時間點)回頭見。
2. 表示頻度
這類副詞常見的有:always, constantly, continuously, continually, ever, frequently, generally, hardly ever, much, never, normally, occasionally(偶爾), often, periodically(定期地,偶爾), rarely, regularly, repeatedly, seldom(很少), sometimes, usually, now and then(偶爾,有時)等。例如:
1)She is constantly changing her mind. (頻度)她老是改變主意。
2)We do meet now and then, but not regularly. (頻度)我們確實偶爾也見面,但不經常。
3)Lester rarely left his room. (頻度)萊斯特很少離開他的房間。
3. 其他一些表示時間的副詞:
主要有:already, early, finally, first, immediately, just, late, long, presently, shortly, since, soon, yet等。例如:
1)I’ll be back presently(shortly). 我一會兒就回來。
2)What decision did you finally arrive at?你們最後做出了什麼決定？
3)Nancy was up early. 南希很早就起來了。
4)He has just had an operation. 他剛動過手術。
分析:
句1)中的presently (shortly)(不久,一會兒),強調從現在算起到將來的某一時刻,時間持續很短；句2)中的finally(最終)強調事件的最終結果；句3)中的early(早)表示動作發生的時間比通常所認定的時間早；句4)中的just表示從過去的某個時間算起到現在,時間持續很短。
二、前面帶有介詞in, at, on和for表示時間的短語
1. 帶有介詞in的時間短語:
in a flash(瞬時), in a lucky hour(在幸運時刻), in an evil hour(在不幸的時刻), in a minute, in a second, in a short time, in a while, in advance(預先), in an instant, in broad day(在大白天), in due course(及時地), in future, in good season(及時地), in no time(馬上), in one’s childhood, in one’s spare time, in one’s teens, in one’s youth, in re-cent years, in some cases(有時候), in spring, in the beginning, in the daytime, in the end, in the long run(最後), in the meantime, in the morning, in the past, in this period, in those days, in time等。例如:
1)He was born in1980. 他生於1980年。
2)The policeman arrived intime and caught the thief in a flash. 警察及時趕到,瞬時抓住了那個小偷。
2. 帶有介詞on的時間短語

2)When he heard the bad news, he burst into tears on the moment. 聽到那個壞訊息,他的眼淚立刻奪眶而出。
3)He always arrives on time in time of an appointment. 約會時他總是很準時。
3. 帶有介詞at的時間短語:

3)At the stage, Tom doesn’t have enough time to write such a long paper. 眼下湯姆沒有時間寫那么長的一篇論文。
分析:
句1)中的at that time(那時)表示某種境遇存在的時間段；句2)中的at times(有時)表示事件發生的頻度；句3)中的at the stage(眼下)表示離說話前後不久的一段時間。
4."介詞for + 表示時間的名詞短語"表示動作持續或狀態存在的時間段:
for ten seconds, for five minutes, for an hour, for two days, for six months, for a year, for a decade, for a whole century, for a long time, for a short while等。例如:
1) On hearing the news, Helen stood there for ten seconds without saying a word. 聽到這個訊息後,海倫站在那裡十秒鐘沒說出一句話來。
2) I feel as if I had left school for a whole century. 我覺得我好像離開學校整整一個世紀了。
三、不帶介詞的表示時間的短語:
just now, so far, last night, right away, the day after tomorrow, the day before yesterday, five days ago, five days before, this week, next week, a week ago, a week before, last month, next month, this year, next year, three months ago, this century, last century等。例如:
1)The old couple haven’t heard from their son so far. 那對老夫婦目前還沒收到兒子的來信。
2) Susan will take the college entrance examination the day after tomorrow. 蘇姍後天要參加大學入學考試。
3) He said his father had died three years before. 他說他父親三年前去世了。分析:
句1)中的so far(到目前為止)是副詞短語,表示到現在為止的時間段；句2)中的the day after tomorrow(後天)表示事件將要發生的時間；句3)中的three years before(三年前)表示過去某件事發生的時間,用於間接引語中。選擇最合適的選項完成句子。
