The new school term has just been started. I need some things for my classes. First, I have to buy six textbooks. They are such expensive that I want to buy them online if possibly. I also need a good dictionary to help me improved my writing. For my math or physics classes, I need a counter. On addition, I have to buy several notebooks to organize our homework. Finally, I will buy some color pens to mark some important point in my textbooks. If my textbooks are in good condition at an end of the term, I might able to give them to new students.
