That state lasted until I went to college, where unlike the problem I came across in the senior middle school, my class was very large and some students spoke better than I did. So, once again, although for different reasons, I was afraid to speak and felt that my English would stay at the same level forever. Only when I took the online course did I come to reap the benefits from English learning.
