Dear Ben,
I am sorry to hear that you are having trouble getting used to life in middle school. In your letter you said that you always felt lonely because of having few friends. I think it is a good choice to join some clubs in your school. In this way. you can make more friends who share the same interest with you. Besides, you d better be friendly to others. Smile at others and you are sure to get a smile in return. On the other hand, you found it difficult to remember English words. Reading more English stories and news can help you learn English words in a practical way. In addition, if you can develop a habit of keeping an English diary every day, it will be easier for you to remember more words. I hope you will find these suggestions useful.
