Dịch: Một trong những sở thích của tôi là nghe nhạc, đặc biệt là các bài hát tiếng Anh. Sở thích của tôi bắt đầu khi tôi là sinh viên năm thứ nhất của Đại học Sư phạm Hà Nội. Tôi dành nhiều thời gian vào nó. Tôi có thể nghe khi tôi đang làm công việc nhà như lau dọn sàn nhà, giặt quần áo, rửa chén ... hoặc khi tôi ngủ ... Tôi yêu Taylor Swift, Rihana ... họ là những ca sĩ tuyệt vời. Tôi có thể học từ vựng tiếng Anh khi nghe các bài hát tiếng Anh và nó cũng làm cho tôi cảm thấy thư giãn.

One of my hobbies is listening to music, especially English songs. My hobby started when I was a first – year student at Ha Noi National University of education. I spend much time on it. I can listening when I am doing my housework such as clean the floor, wash clothes, wash dish…or when I sleep…I love Taylor Swift, Rihana…they are great singers. I can learn English vocabulary when listening to English songs and it also make me feel relaxed.
