题目

Dear Ralph, I am an university student. I once thought life at the university must be excellent, but now I changed my mind. I have three roommates, and I was the last one to move into the dormitory. Last term, I got along peacefully and happy. But I find they are not willing to be with me now. They don't talk with me, and they've become cold toward me. Many time, I have wanted to talk with them about how I felt like, but I failed to find an opening. When leaving alone, I always recall this sadness. But I am an honest student. Why don't I win true friendship? 答案：1. a改为an;    2. changed前加have;    3. I改为We;     4. happy改为happily;   5. cold改为colder; 6. time改为times;  7. have去掉;        8. how改为what;  9. leaving改为left;    10. don't改为can't
