I am going to make up three sentences below.
(1) Three weeks ago, I was writing a short essay for five days.
(2) John was scoring a lot of goals for many years.
(3) During Tim's one-week stay in my home, I was working on my project for five days.
I am using the past continuous tense because the action mentioned in each sentence happened over a period of time. Does this tense work in my examples? Thanks a lot.
