短文改错。 I still remember my middle school life in Tianjin yet. I was then in a school for students from Tibet. As we were all left home at early age, we met lots of problems in our daily life. We had to do the washing , cleaning and shopping by us. However, we seldom felt lonely or helplessly. We enjoyed our happy life. At weekends, we would play basketball, swimming in the pool or go for a picnic. We were living in a big family. We treat each other as brothers and sisters. If any one in us had any difficulty in our life and study, the other would help him out. It has been five years when we graduated, but those memories are as sweet as ever before. 1______ 2______ 3______ 4______ 5______ 6______ 7______ 8______ 9______ 10______
