【5.20】★每日一句★We have to submit the final report by Thursday.
We have to submit the final report by Thursday.
我们必须在星期四前缴交期末报告.
=============================================
英文里每种时间的单位都要使用不同的介系词, 像年是用 in, 例如 in 1999, 月也是用 in, 例如 in July, 时间用 at, 例如 at 4:55, 日的话则是用 on, 例如 on July 4, 但是有时候也可以用 by 来表示在不迟于那个时间. 例如例句 "We have to submit the final report by Thursday" 指的是下星期四前交, 但如果说成 "We have to submit the final report on Thursday." 则是指星期四要交. 二者意思不尽相同. 不过这种区别对当学生的我们似乎没差, 反正每次也是要拖到最后一天才会交.
大家顺便可以区分一下 within two weeks 和 in two weeks 这二者之间的区别. 一般而言, within two weeks 是说二周之内, 而 in two weeks 是说二周之后, 但不得迟于二周.
