I have many friends, and today, I will introduce two of them to you. Their names are Helen and Alice. They have many differences and similarities. For example, Alice is taller in height than Helen, but Helen is more popular than Alice. (这样讲 Alice 没有 Helen 受欢迎好像不太好吧)
Both of them are friendly and cheerful, but Helen is better in studies than Alice. These are my two best friends, what about you?
