I still remember how nervously I was on my first day in the new school t here years ago, when I found difficult to follow my teacher in the first English class. The teacher spoke English throughout the class, that was totally different from lessons 1 had taken before.
In the morning class the next day, the English teacher came to me while I am reading the text aloud as other students．After listen to me for a while, she gave me a big smile and said he liked my voice very much．The smile shone on the whole day and the following days．A week later, I was volunteered to take charge of English study in my class．Thank to the comforting smile in my first morning class, I began to confident．
这是短文改错，答案我有，不知道解析，看不懂啊，求大神帮帮忙
