I have many friends, so my best friend is called Li Ting. I met him about five years before in a class where we attended together. Though we didn’t know each other before, but we have lots of things in common. At that time, the pressure on us to study was quite heavily. We both hoped to pass the National College Entrance Exam and entered university. She was very diligent and we both studied hard. I was good at maths while she good at English. Finally, we both did very well in the exam. In fact, she gave me a lot of helps with my study. Our friendship has growing a great deal over the last five years.
