    Mobile phone has become a problem for middle schools. Some middle schools in Australia have banned students from carrying mobile phones during school hours.

    Mobile phone use among children has become a problem for the school this year. Several children have got mobile phones as Christmas gifts, and more students will want them.

    Mary Bluett, an official, said mobile phone's use is a distraction to students during school hours and it also gives teachers so much trouble in their classrooms. Teachers were also saying that sometimes students might use phone messages to cheat during exams.

    She said some schools had tried to ban mobile phones. Some parents felt unhappy because they couldn't get in touch with their children.

    Many teachers said students should not have mobile phones at school, but if there was a good reason, they could leave their phones at school office. They also said there were many reasons why the students should not have mobile phones at school: they were easy to lose and were a distraction（分散注意力） from studies.

    Many people say that they understand why parents would want their children to have phones, but they think schools should let the students know when they can use their mobile phones.

    Jan Mela isn't like most kids .Two years ago , he lost an arm and a leg .But that didn't stop him.

    On Saturday ,the 15—year-old boy from Poland（波兰）walked to the North Pole（北极）without any help.

    “If I can do it, other people can do great things, too,” Mela said before he went.

    Polish newspapers said Mela is the youngest person and the first handicapped（残疾的）person to walk to the North Pole.

    How did Mela lose an arm and a leg? He had an electrical（电的）accident .Now, he walks with the help of a 62,000-yuan man-made leg.

    After the accident, Mela felt sad for himself. But he didn't lose hope .One day, he met Marek Kaminski, a Polish explorer. Eight years ago, Kaminski went to the North Pole and the South Pole in the same year. Mela wanted to see the North Pole, too. So Mela asked Kaminski if they could go together next time .Kaminski said yes!

    It took Mela 21 days to get to the North Pole .The last three or four days were really hard because of bad weather .But Mela kept going.

    “I didn't think we would make it,” he said, “Then, things got better.”

Traveling can be expensive. But there are some ways to save money when traveling. Try the advice below on your next vacation and your wallet will thank you.

Look for city tourism cards (旅游卡). With the card, you can pay less at restaurants and shops. You don't have to wait for a long time at busy tourist attractions(旅游景点). You might even get free tickets to top tourist attractions. City tourism cards can save your money and time without question.

Don't get the best room. How long will you stay in your room? Will you just be sleeping there? Do you really need a bigger room with a good view? Find a hotel outside a city. It can help you save some money by choosing a hotel away from big tourist attractions, because you are always doing the same— go to the attractions and then return to your hotel to sleep.

Book a room with a kitchen. Although some people might not like to cook on vacation, I don't mind making breakfast in my room. We always eat at a nice restaurant on our last night of the vacation. I always prefer(更喜欢) to eat breakfast and lunch at the hotel and then spend much money on a delicious supper.
