I fell in love 97 English at a very young age, because I thought it was a wonderful language. Full of strong wishes of 98 English, I began to learn it. But soon I found it 99 than expected. There were too many words, expressions and many other things to memorize (记忆). And even if you know how to write them, you can’t 100 them correctly. And I did rather badly in my first English test. While I was in 101 , my English teacher gave me much help. I wish to practice speaking English with foreigners every day!
