編輯/蕭譯婷

即使我們已經學會如何表達時間,但你是不是也時常在時間前面加上錯誤的介係詞(preposition)呢?

Learn British English Free的講師Chris便提出了該如何正確使用介係詞來表達時間,並輔以實用例句來增強記憶喔!

1. By

Use “by” to describe a time that something has to be done by, is usually done by, or a point by which something was done:
用by來表示某件事情應該、通常或已經被完成的時刻。
e.g. You must clean your room by tea time.
你在下午茶時間時一定要整理完你的房間。

2. at

Use “at” to specify what time an action is done / will be done / was done at:
用at表示某件事情完成的特定時間。
e.g. He will catch the train at 1000.
他會在早上十點搭上火車。
e.g. I usually hit the gym at seven in the evening.

e.g. They left at nine this morning.

3. in、during、throughout、over

Use “in”, “during”, “through”, “throughout” and “over” to discuss periods of times for actions:
用in、during、through、throughout、over來表示一段時間。
e.g. She worked in / during / throughout the summer.

e.g. My current contract will end in four months’ time.

5. ago

Use “ago” to explain how long it is since something happened in the past:

6. since

Use “since” to describe a period of time in the past up until the present or another specified point of time (use with present perfect or past perfect tense):

e.g. I’ve been in my present job since 2005.
我從2005年開始就做這份工作了。
e.g. At the time of his death, he’d been suffering from the illness since he was diagnosed three years before.
