Ngữ pháp By, Until và By the time

A. Cấu trúc by + từ chỉ thời gian trong tiếng Anh

by + từ chỉ thời gian có nghĩa là không muộn hơn:

- I posted the letter today, so they should receive it by Monday.

(= on or before Monday, not late than Monday)

(Hôm nay tôi đã đi gửi thư, vậy chắc họ sẽ nhận được thư vào thứ hai. )

(= trong hoặc trước ngày thứ hai, không muộn hơn ngày thứ hai)

- We'd better hurry. We have to be at home by 5 o'clock.

(= at or before 5 o'clock, not late than 5 o'clock)

(Chúng ta nên khẩn trương. Chúng ta phải có mặt ở nhà lúc 5 giờ. )

(= lúc 5 giờ hoặc sớm hơn, không muộn hơn 5 giờ)

- Where's Sue? She should be here by now.

(= now or before now — so she should have arrived already)

(Sue đâu rồi? Cô ấy lẽ ra phải có mặt vào lúc này rồi. )

(= lúc này hoặc sớm hơn — cô ấy lẽ ra đã phải tới rồi.)

Bạn không thể sử dụng until với nghĩa như vậy:

- Tell me by Friday whether or not you can come to the party.

(không nói 'Tell me until Friday')

(Muộn nhất là vào thứ sáu bạn hãy cho tôi biết bạn có thể đến dự buổi liên hoan hay không.)

B. So sánh Until và Till trong tiếng Anh

Chúng ta sử dụng until (hoặc till) để diễn đạt một tình huống nào đó tiếp diễn trong bao lâu.

Ví dụ:

- "Shall we go now?" "No, let's wait until (hoặc till) it stops raining."

("Chúng ta đi ngay bây giờ chứ?" "Không, hãy đợi cho tới khi trời ngừng mưa.")

- I couldn't get up this morning. I stayed in bed untill half past ten.

(Sáng nay tôi không thể dậy được. Tôi ngủ mãi tới 9h30.)

- I couldn't get up this morning. I didn't get up until half past ten.

(Sáng nay tôi không thể dậy được. Tôi không chịu dậy cho tới 9h30.)

So sánh until với by:

until: sự việc nào đó được tiếp tục tới một thời điểm trong tương lai. - Fred will be away until Monday. (so he'll be back on Monday) (Fred sẽ vắng nhà cho tới thứ hai. (Anh ấy sẽ trở về vào thứ hai)) - I'll be working untill 11.30. (so I'll stop working 11.30) (Tôi sẽ làm việc tới 11.30. (Vậy tôi sẽ kết thúc công việc lúc 11g30).)

by: Sự việc sẽ xảy ra không muộn hơn một thời điểm tương lai. - Fred will be back by Monday. (= he'll be back not later than Monday). (Fred sẽ trở về vào thứ hai. (=Anh ấy sẽ trở về không muộn hơn ngày thứ hai)) - I'll have finished my work by 11.30. (I'll finish my work not later than 11.30) (Tôi sẽ hoàn thành công việc lúc 11g30 (tôi sẽ kết thúc không muộn hơn 11g30))

C. Cách sử dụng By the time trong tiếng Anh

Bạn có thể nói by the time something happens (thì hiện tại). Hãy xem những ví dụ sau:

1.

(= the shops will close between now and the time we get there)

(= trong khoảng thời gian chúng ta tới cửa hàng thì chúng sẽ đóng cửa rồi)

2.

- (from a letter) I'm flying to the United States this evening. So by the time you receive this letter, I'll be in New York.

(= I will arrive in New York between now and the time you receive this letter)

(= Tôi sẽ tới New York trong khoảng thời gian từ bây giờ đến khi anh nhận được bức thư này)

3.

(= it look her a long time to get to the party and most of the guests went home during this time)

(Xe hơi của Jane bị hỏng trên đường tới dự tiệc tối qua. Lúc cô tới nơi, phần lớn khách đã ra về. )
