broken English sometimes is good

I read this article carefully and I fout that the author is very good at writing since it's easy to understand,like her mother said. She discussed both advanteges and disadvantage about broken english and perfect english. yes, I have the same sence with her according to myself(I am an international student)
Lots of people thought her mother's english is limited.But if we thought it in deepth, we could find that even though the sentences are simple but it represent whole information and what she want said. In some case, I prefer to say broken English . This is my first time to go abroad to get further study. When i talk with my classmates or ask for questions ,I usually speak broken english( I surppose it is broken) but almost of them can know what I want to say. Unlike in my coutry, when I speak english , I will consider many aspects about grammor and thus my thoughts were limited. So this inllustrate that limination is not always limination.
however, there is no doubt that we were in trouble when we lack ability to use second langudge.
For instance, there are two general problem categories . First is langudge problem. it means you will spend more time on reading book as there are many unfimilar words . communication is also langudge problem. It is difficult for almost international students to talk with natives very fluently. The second is academic issues. the textbooks and lectures confused us.
