    will complete/will have completed

    Workers ______ (complete) the new roads by the end of this year. By the end of next year they _______ (finish) work on the new stadium.

    This test problem comes from NEW CONCEPT ENGLISH 2 (unit 2). I would think 'will complete/will have completed' and 'will finish/will have finished' could be used. Am I right? Can we use both tenses whether we put the time phrase 'by the end of this/next year' at the beginning or the end of the sentence?

    Could I ask native English teachers to help me please? Thank you in advance.

    I think Joham would be helped to know, "Why?"

    L. G. Alexander: She will arrive/ won't arrive by 5.00.
    Martin Hewings: The installation of the new computer system will be completed by next month.
    OXFORD 6: Output will triple by next year.

    I've read many more such sentences and so feel puzzled.

    Hoping to get further help from you. THANKS A LOT.

    David's post (#3) adds insight here. In other words, context is everything as it determines which of the tenses you should use.

    Re: will complete/will have completed

    Scenario:
    Two people in a room, and John is telling Paul what presents he got for his birthday. A complete stranger enters, says, "The roads will be completed by the end of the year", and exits.

    Question: Does John turn to Paul, tut, tut, and say, "He should have said,'The roads will have been completed by the end of the year'"?
    or does he say, "What the hell was that all about?"

    The moral? You can learn the forms that verbs take by looking at single, isolated sentences: He runs/he is running/he has run/he would have run/he would have had to have run..."
    and all are correct. But why a person chooses to say:
    Martin Hewings: The installation of the new computer system will be completed by next month.
    instead of
    The installation of the new computer system will have been completed by next month.
    cannot be understood without knowing the conversation or other context in which this sentence is then uttered.
    So - whether we wish to talk about 'roads' or 'computer installations' that will have been completed' versus 'will be completed', would some adventurous sole like to come up with two contexts to show Joham the difference - why a speaker would choose one form over the other in that context?

    Smile Re: will complete/will have completed

    If you say:

    She will go to Mexico by the end of next month.

    you express her determination or volition to do so, or your expectations concerning her actions.

    If you say:

    She will have gone to Mexico by the end of next month.

    you express the outcome of her actions - the aftermath of her determination/volition.

    Yes. But 'will' can also be used merely to express the future.
    You have given another instance which shows show important context is.
    There is a difference between:
    "The Queen will go to Mexico, and then pay a visit to Panama."
    and
    Father, banging fist on table: "How dare my daughter defy me! She damn well will go to Mexico and get a quickie divorce if I have to drag her to the border myself."

    Re: will complete/will have completed

    I'm sorry but I still don't understand.

    Oxford 6:
    1. Patches of fog will clear by mid-morning.
    This should be a weather forecast (prediction). (Does it equal 'Patches of fog will have cleared by mid-morning'?)
    2. The mist will clear by mid-morning.
    3. By next year all the money will have been spent. (Could we say '...will be spent' without changing the meaning?)

    Martin Hewings:
    He went completely grey by the time he was 25. (Does it mean 'He had gone completely grey by the time he was 25'?)

    All my sentences are taken from British dictionaries and grammar books and all have no context.

    Looking forward to your further kind help. Thank you ever so much.
