The Price of Success
One problem for schools is that many students do not want to study hard. As a result, they perform (表现) poorly in their classes. This is especially true in the United States, where average scores for math and science are lower than in many other countries. In recent years, schools and charities have been looking for ways to help students get better grades in these subjects. An organization called the LMD Foundation introduced a program called Learn and Earn recently.
In the program, money was used to get a group of students to study harder in math and science. In addition to the normal school day, they went to after-school classes for four hours each week. The students were paid eight dollars for each hour of after-school class. By the end of the year, the students in the program had higher grades than a similar group of students who had not taken part.
Not everyone thinks that this is a good idea, though. TV reporter John Tulenko studied data (数据) from a similar program. He found that students' grades went back down when they stopped getting paid. Many people are worried about this. They think that the students study because they want money, not because they enjoy learning. Also, some people believe that these types of programs are a bad idea because it is a large part of a teacher's job to get students to study. If students are given money, some teachers might stop trying to do this.
However, others believe that these learning programs can be helpful for students from poor families. Many of these students do part-time jobs after school, and some even quit school at a young age to work. Some do this to help get money for their families. Others feel that they can learn more by working than by going to school. Programs like Learn and Earn let these students stay in school and still make money.

On Friday, our teacher told us that there would an English corner in front of our teaching building. I set about soon after the last class in the afternoon. To my joy, the English corner had just been on for a few minute. I joined them on their talk. At first, I was afraid that my English was so poor and limit that I couldn't make myself understand. I was also afraid that anyone might laugh at me. But a smiling face here or an encouraging nod there soon put me at ease. Though I speak to them only in simple English that day, I believe in future I will make a greater progress.
Parents should help their children understand money. So you may start talking about money when your child shows an interest in buying things, candy or toys, for example.
Tell them the basic use of money.
Begin explaining the use of money by showing how people buy things. If your child wants to have a toy, give him the money and let him hand the money to the saleswoman. When your child grows a bit older and understands the use of money, you can start explaining more ways of using money.
Give them money lessons.
If you must say no to a child's request to spend money, explain, “You have to make a choice between this and that toy.”
You can show your child how to make choices between different brands（牌子） of a product so that you can save money. If he chooses the cheaper brand, allow him to buy other things with the money saved.
A. Make wise decision.
B. Tell them the value of money.
C. Allow the child to choose between them.
D. Tell your child why he can or cannot have certain things.
E. Ask yourself what things that cost money are most important to you.
F. Talk about how the money bought the thing after you leave the toy store.
G. The best time to teach a child anything about money is when he shows an interest.
