The usage of prepositions is idiomatic. So it varies depending on the speaker.You watching: Toan bộ kiến thức về giới từ in on at trong tiếng anh + bài tậpBạn vẫn xem: Grammar"At the weekend", "at a weekend" and "at weekends" are used in British campusstudylab.vn; "on the weekend", "on a weekend" và "on (the) weekends" in American campusstudylab.vn.Generally speaking, words which refer to a period of time take in, lượt thích "in the morning", "in the month", "in the daytime" etc. Words which refer khổng lồ an exact point of time take at, lượt thích "at 9 p.m.", "at dinner", "at Christmas", "at noon" và so on. Words which refer to a day or date take on, lượt thích "on Monday", "on 18th", "on Tuesday morning" etc. So according lớn this rule the word "weekend" should be the object of "in". But it is not. We have never heard "in the weekend"!So the answer is the usage of preposition is merely idiomatic.

For the most part, the delineation occurs at the period of a day, example: "What are we doing on Friday?" và "What are you doing at 5:00pm?"Why you need "the", which is to lớn say that answer b is not correct, is that "weekend" is ambiguous by itself. Example: "are you miễn phí on the weekkết thúc so we can get together?" means this coming weekend or the implied weekover in reference whereas "are you không tính tiền on a weekend?" just means any old weekover.

"At" is more particular, for a smaller place or shorter time, whereas on/in are used for longer durations or larger spaces. "Let"s eat at an Italian restaurant at 9pm" against "Let"s eat in downtown on Friday".Going by this xúc tích và ngắn gọn, "on" should be used.So you should use "the" too.See more: Những Cách Gọi Điện Thoại Miễn Phí Từ Internet, Các Trang Web Gọi Điện, Nhắn Tin Miễn PhíHence, from your choices, F is the correct answer.D could make sense too, if you have sầu been disturbing someone for many weekends. So your "disturbee", for lachồng of a better word, would know that you acknowledge the fact that you disturb hyên on most, if not all, weekends.

But "at/on weekend" could refer lớn a past or future event. Therefore to avoid ambiguity, reference should be made to lớn whether it is a weekkết thúc in the past, future or both.Whilst a disturbance could be a instantaneous sự kiện (such as making a single loud noise), it is more likely to lớn have a certain amount of length lớn it. Moreover, the fact that it is at/on the weekover implies both Saturday và Sunday - reinforcing the length of the disturbance. Therefore I would suggest that "over the weekend" is actually better as it clarifies that the disturbance is happening for a duration within the time period defined as the weekover. But if you are not fond of "over", "at" would be my second preference as I am BE.Taking this further, my view is that "at" should be used for events that are not days of the week (at Christmas, at Easter, at the weekend, at lunchtime, at 9 o"clock) irrelevant of length, và "on" where the time is a day of the week (on Saturday). I would argue that this is to lớn vì chưng with the fact that "at" implies a certain flexibility in the period, whereas "on" implies rigidity. "Saturday" is a defined period of a comtháng unit of time (days), if it happens on Saturday, it happens only on Saturday. Whereas "at 9 o"clock" implies starting at 9, but continuing for an flexible length of time; similarly "at Christmas" implies starting at some point during the Christmas period, not necessarily "on Christmas Day"; "at the weekend" implies some point during the weekover which could either be Saturday or Sunday or both.The disturbance is subjective. Therefore I would suggest "Sorry if I disturb" if you are unsure of whether it is considered a disturbance, or "Sorry that I disturb" if you are aware that it is considered a disturbance.See more: Cách Làm Cuộc Sống Vui Vẻ Hơn Mỗi Ngày Cho Chính Bản Thân BạnTherefore my preference would be along the lines of, but could equally be adapted to lớn suit the specific situation:"Sorry if I disturb you over the weekkết thúc." (a potential number of future incidents)"Sorry to lớn have sầu disturbed you at the weekend." (isolated past incident)"Sorry for any disturbance at weekends." (ongoing problem).
