    Default present perfect and past simple tenses

    Chào mọi người
    Xin lỗi nếu câu hỏi này quá đơn giản... hoặc đã được trả lời đâu đó
    Mình để ý mình thấy trong văn nói (có thể cả văn viết) rất nhiều thì (tenses) thực tế ít được sử dụng, hoặc có thể sử dụng cách diễn đạt khác. Nhưng có 2 thì được sử dụng rất nhiều là past simple và present perfect nhưng mình lại không thực sự xác định được khi nào thì nên dùng Past simple và khi nào thì dùng Present perfect. Thật buồn phải thừa nhận như vậy!
    Vì trong rất nhiều trường hợp mình thấy nếu theo đúng ngữ pháp thì phải sử dụng present perfect là đúng nhưng tác giả lại sử dụng past simple
    ý mình là họ không chỉ rõ thời gian hoặc khoảng thời gian trong qk mà vẫn sử dụng past simple bình thường.
    Làm thế nào để xác định cách dùng chính xác các thì này
    thanks a lot!

    hai thời bạn hỏi khác nhau như đen và trắng. Nhưng cố tình diễn đạt của người phát và cảm nhận thời gian của người thu có một khoảng trộn màu xám. Bạn phỉa hiểu là người ta làm việc gì đó đã xong chưa hay đã làm mà chưa xong. Thế thôi.

    Thank you very much indeed for your helps!

    Here is one of the paragraphs which makes me a bit confused
    I just copy it from somewhere. (Sorry the author)

    “I am in bad mood today, I will tell you why. I have a TOOTHACHE! Aaaaagh!
    Unfortunately, I won’t be able to go to the dentist until next week, so for the next few days I have to deal with my toothache by myself. I am taking painkillers, of course, and some of my friends have suggested remedies. One friend told me I should use hot, salty water and another suggested oil of cloves”

    The problem is that, can I change these sentences above like this
    "…of course, some of my friends suggested remedies. One friend told me I should use hot, salty water and another suggested oil of cloves". (I dont want to specify when it happened)

    "…of course, some of my friends have suggested remedies. One friend has told me I should use hot, salty water and another has suggested oil of cloves"

    Chẳng có gì khó hiểu hay làm bối rối trong việc sử dụng thì ở đây:

    Bạn cần để ý:
    1. Đây là đoạn văn kể chuyện trực tiếp (direct speech) do đó lời nói đang ở thì hiện tại.
    2. Những chổ xài present perfect vì người nói nhắc lại ý kiến hay lời của người khác mà không nói rõ là nói khi nào, vào thời điểm cụ thể nào ở quá khứ.
    Phần câu cuối dùng simple past vì đã bắt vào mạch chuyện rồi nên không dùng present perfect nữa.

    "…of course, some of my friends suggested remedies. One friend told me I should use hot, salty water and another suggested oil of cloves". (I dont want to specify when it happened)

    theo tôi đổi như vậy thì OK không sao cả. Ta có thể dùng simple past để kể chuyện. Tuy nhiên y như cũ (phần nguyên) thì vẫn tốt hơn.

    Thí dụ :
    I had left home before she got up = I left home before she got up
    Vì đã có trạng từ before cho biết việc nào xảy ra trước, việc nào xảy ra sau nên không quá cứng ngắt theo thì.

    For me it will still sound good if you change the highlighted phrase into simple past. Though you you read the story again, it wouldn't emphasize that his/her friends have suggested such and such.

    Apart from not indicating the time of the even, to me present perfect can also be used to emphasize that something has been done. Like in this situation here:
    -Mother: Have you done your homework? (Con làm bài chưa?)
    -Son: I have/ or I have already done my homework. (Con đã làm rồi)
    The son doens't just want to say "I did my homework" because it wouldn't make as big an impact to his mother's question.

    The son can answer grammatically: "I did my homework this morning" (if the question asked in the afternoon or in the evening)
    More example:
    _Did the postman come yet? (the question asked in the evening implies that whether he came in the morning)
    Naturally, the people who is asked knows how to answer
