    Summer schools Summer vacation means long days, sleeping in or enjoying the summer sun. It is quite true for students to enjoy a rest after a long and difficult year. But more and more parents fear their kids forgetting a lot of knowledge, so they send their children to summer schools. Because summer schools can help children go over the knowledge that they have learnt during the school year.

    In summer schools, students probably study in a more relaxing situation and can come up with interesting topics for discussion with their teachers. Usually, the number of students attending summer schools is smaller, so this gives them a good chance to connect with other students and teachers better. If a student has failed a course, summer schools may help him or her. Moreover, they are building their creativity （创造力）and imagination（想象力）as well as learning social skills.

    On the other hand, summer schools bring children problems at the same time. It takes children the whole summer vacation to learn without playing. That is too long. As a result, it may make them less interested in school during the coming year.

    For many students, taking summer classes can be a tiring experience. Teachers teach the subjects too quickly, which only harms the whole education of students. Summer schools are usually expensive. They usually offer only a few subject. So many students have to take classes that they don't like.

    A summer school can be a good chance for students who need it, but it can be difficult for students who need a rest. So you can decide whether a summer school is suitable for your children.

    Some time ago, an old businessman had a large store in Boston. He wanted a boy to work for him, and he put an advertisement in the newspapers. The next morning, many boys came to the old man's office, asking for the job.

     There was a post（柱子）by his desk, and there was a nail in it. He took a walking stick and said, “Everyone has three chances. If anyone can hit that nail（钉子）on the head with this stick more than once, I will give him the job.”

    The boys thought it was very easy. They all tried, but nobody could make it. So the old man said, “I'm sorry I can't take any of you,” and they left.

      He kept the advertisement in the papers, and the next morning more boys came, and among them he saw a thin boy who had been there the day before. The boy hit the nail successfully for three times. The old man felt surprised and asked how he did that.

     “Yes,” said the boy, “I failed yesterday, but I thought that if I kept on trying a while, I could do it. So I went home and practiced hitting a nail with a stick till I could do it, and I got up very early this morning, and tried again.”

    The old man said, “You are the boy for me,” and gave him the job. Whatever the boy had to do, he tried to do his best. It was not very long before he became the best clerk in the store.
