Before explaining this structure to children, it is very important to understand it by comparing it with other structures. There is something we did in the past and the matter is over. That is, I did matriculation in 2009. In some actions we show that we were working continuously in the past. That is, during matriculation, I was learning English. Third are the things I do over and over again every day. That is, I read the Quran daily. And if the same thing is done again and again in the past, it will be done under the structure. That is, I used to read Quran in the school assembly, or I used to take English class every week during matriculation. Here is a way to repeat something. Although ongoing. But language is used for a specific purpose. I had another motive when I mentioned the release above. Telling to be repeated, my purpose changed. In short, expressed the habit. Check out some examples below.
