  “Sometimes you just get a strict teacher. Instead of letting others know that this isn't your favorite class, make an effort to show your teacher you are doing your best.”

  “Learn to put your activities in order of importance. School comes first, and if you just study as soon as you get home, it's OK. You can also relax and play computers or do other things you enjoy. But don't lose yourself in just getting by. Try hard! And don't be afraid to get help from teachers.”

  “If you have trouble getting along with a specific teacher, pray about it. Ask God to help you see that teacher through HIS EYES, not your own. And talk with that teacher. Good communication can strengthen any relationship-even with a hard-to-get-along-with teacher.”

“Being a good student means being organized. Remember to bring all your supplies, everything to each class every day. Make sure that you'll never skip (逃) class. And when you're in class, really pay attention! Don't let yourself daydream or write notes to friends. Completing your homework on time is also important.”

  “When you're having trouble getting along with a certain teacher, stay calm! You may not agree with him or her, but you've got to remember the teacher is the authority (权威) figure. So make sure that you're respectful and open-minded. Ask for a specific time when the two of you can talk. Explain yourself and address (探讨) the problem, not the teacher.”

  “Being a good student means studying often, not just cramming (填鸭式的用功) before a test. Identify (识别) your weak areas. For example, maybe you don't have good reading skills or it's hard for you to take notes. Once you identify what your weakness is, ask for help in these specific areas. Be willing to go in early or stay after school to get extra help. Go into the school year knowing that being a good student will require time and effort!”

Simon cannot go anywhere       the wheelchair these days because he has broken his left leg.

    When your dream is to become a footballer and play for Barcelona, nothing should get in your way — even if you have no feet.

    An 11-year-old schoolboy Gabriel Muniz, who was born without feet, will fly from his home in Brazil to take part in the Spanish club's summer training camp. Although he is disabled, Muniz is one of the top players at the school and captain of his gym class. He can run, dribble (运球), pass and strike the ball as well as any of his able-bodied teammates. He spends all his spare time on the football pitch.

    His best friend Lucas Santos spoke about his abilities on a video for The Sun, “He is skillful, he goes after it, he is fearless and he knows how to organize plays. He also makes good passes.” Mum Sandra was thrilled that her son would achieve his dreams. She said, “He started walking before he was one. We would go after him, expecting him to keep falling, but he never fell.” Muniz's gym teacher added, “He is challenging the social norms (标准). When he arrived there, no one believed in him.” But he showed to everyone that he could play as well as any other boy. So he was invited to go to Spain to show his talent.

    The Spanish La Liga soccer club has offered to fly Muniz to Spain in September, where he'll be able to show off his “fancy footwork” and meet his idol, Barça soccer player Lionel Messi.

    Muniz wears a prosthetic (假体的) ankle and foot to help him get around in rainy weather. He knows that his disability means he'll never be able to play for a professional football team and so Muniz is hoping that football will one day become a Paralympic (残奥会的) sport.
