  1. 12. How long have you worked in that factory?
    – When + did + S + start/begin + to Vinf/Ving … ?
    = How long + have/has + S + P2 …. ?
    16. 
    => I spent two hours finishing my homwork.
    => It took me two hours to finish my homework.
    – S + spend/spent + time + Ving = It + takes/took + sb + time + to Vinf
    -> Mất bao lâu để làm gì
    17. 
    => My mother spends less than an hour preparing breakfast.
    => It takes my mother less than an hour to prepare breakfast.
    – Giống câu 16
    18. It’s time to go home.
    – It’s time + to Vinf : Đó là thời gian để làm gì
