Mary was born in Briston, England. She's now in grade 8. Her school studies 6 days a week./ She goes to school 6 days a week. In the morning, she eats breakfast at home. And when lunch comes, she eats at her school's canteen. She has stayed with her Uncle near my house in Viet Nam for 2 months but she won't be here any longer, she will return to England next month.
NOTE: Vì câu "she HAS STAYED with her Uncle...."
Do for + khoảng thời gian, tức là khi dùng câu này ta phải dùng HTHT (có for là dấu hiệu nhận biết)
