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.

    The Great Wall of China is called the "Ten thousand Ii Great Wall" in Chinese. In fact， it' s more than 6，000 kilometers long. It winds its way from west to east， across deserts， over mountains， through valleys till at last it reaches the sea. It is one of the wonders of the world.

    The Great Wall has a history of over twenty centuries. The first part of it was built during the Spring and Autumn Period. During the Warring States Period， more walls were put up to defend the borders of the different kingdoms. It was during the Qin Dynasty that the kingdom of Qin united the different parts into one empire. To keep the enemy out of his empire， Emperor Qin Shihuang had all the walls joined up. Thus， the Great Wall came into being.

    The Great Wall is wide enough at the top for five horses or ten men to walk side by side. Along the wall are watchtowers， where soldiers used to keep watch. Fires were lit on the towers as a warning when the enemy came.

    It was very difficult to build such a wall in the ancient days without any modern machines. All the work was done by hand. Thousands of men died and were buried under the wall they built. The Great Wall was made not only of stone and earth， but of the flesh and blood of millions of men.

    Today the Great Wall has become a place of interest not only to the Chinese but to people from all over the world. Many of them have come to know the famous Chinese saying: "He who does not reach the Great Wall is not a true man."
