I found these sentences in a grammar book:

They're building a new hospital. It will be finished soon.

I'm wondering, since the simple tense means completion, can we say

They're building a new hispital. It will be built soon.


  • what simple tense are you talking about? There is a future passive "will be built"

  • @JamesK Yes, the future simple passive. As I know we can say "It will be built" only about objects that will be finished. That's why I've asked this question. Jun 7, 2022 at 6:42

"be built" is quite vague, it can mean it has not started building or is close to finishing the building. Meanwhile "be finished" means it is close to being finished. So I would rather stick with "be finished" here.

  • Thanks! Is it grammatically wrong to use the option with "be built"? As I know we can say "It will be built" only about objects that will be finished. E.g. It was built two years ago. = It was finished two years ago. Jun 7, 2022 at 6:45

    No it is not grammatically wrong to use it, it just a little vague, so you can use it @IlyaTretyakov

    It was built two years ago doesn't necessarily mean that the construction was finished exactly two years ago; the work could have been going on for part of the year before last. Jun 7, 2022 at 7:50

    "It was/will be built" means that the construction took place/will take place. When speaking of an older building, "It was built in 1960" probably means that it was completed in that year. However, for a recent or current project, 'being built' may well refer to the ongoing work rather than the completion. Jun 7, 2022 at 13:02

    Oh, dear - this is very hard to explain! In this case, you would probably say I did some work on the model ship that I'm building. Jun 7, 2022 at 16:08
