【题目】 One day, a student was taking a walk with a professor. As they went along, they saw a pair of old shoes lying in the path. They were a poor farmer’s, who was working in the field nearby.

The student turned to the professor and said, “We will hide his shoes, then hide ourselves behind those trees, and wait to see what he will do.”

“My young friend,” answered the professor, “We should never make fun of the poor. Why not put a coin in each shoe, and then we will hide ourselves and watch?” The student did so and they both hid themselves behind the trees.

While putting on his coat, he put his foot into one of his shoes, and felt something hard. Then he bent down to feel what it was, and found the coin.

There is another thing after you select the courses and the teachers. How to buy textbooks makes each student feel hard. The textbooks in America are very 5. Each copy is about $30-50.
