    London has a new magazine. But it is not printed(印刷) on paper. Everyone who has a television can receive it because it is on TV.
    In order to read this magazine you have to have a decoder (解码器). Each page of it is numbered, so you only have to dial the number to choose which subject you want to read about. There are all kinds of information ---everything is included from cooking to the latest sports news.
    If you want to read the news, the first thing you have to do is to turn to the back page, which has an easy-to-remember page number, 100 for example. Then you start choosing what you want to read. The news is on page 101 to 109, so you put in the numbers and the news appears written across your screen. Perhaps you want to go out in the afternoon, so you press 181, and a brightly colored weather map appears on the screen. But the weather is terrible, so you decide to go shopping and dial 162 for a list of the week’s best bargains. But should you drive or take the train? To answer that question you only have to press 189 for the traffic report. It is very simple to use. But probably the best thing about the service is that it is being updated all the time. Journalists type new material directly onto the screen and the whole pages of the magazine can be replaced in minutes.
    London already has three services. One, sent out by TV, is called ORACLE while the other two, on BBC, are called CEEFAX because they let you see facts. Although CEEFAX and ORACLE have been operating for some time, they have not been well publicized(宣传). BBC engineers do not think that their idea will ever replace books and newspapers because they can be taken with you everywhere. But many people would agree that is a breakthrough(突破) as great as the invention of printing, which could not just change our reading habits but our whole way of life.
    小题1: We can know from the passage that in London        .
    A．the magazine is available at any local home
    B．most of the postmen will lose their jobs some day
    C．everyone can read this magazine if they have a television
    D．the readers can get various kinds of information staying at home
    小题2:In the sentence “Each page of it is numbered,” the word “it” refers to the        .
    A．magazine B．programC．decoderD．subject
    小题3:According to the passage, the “decoder” is used to help people        .
    A．work out the total(合计) of certain numbers
    B．read the information sent by TV signals
    C．go shopping and have other entertainment
    D．receive some special TV program for entertainment
    小题4:The passage is mainly about        .
    A．a new magazine printed in London
    B．an up-to-date way of getting information
    C．a popular TV program about magazines
    D．an advanced technology helping people communicate

    With more and more farmers working in big cities, their children go into the cities, too.However, problems appear. One of these problems is that is difficult for these children to receive education in cities.
    Luckily, there are some free schools for them, but they are not enough. Ten-year-old Li Xin is one of the lucky girls who get a chance to study in one of these schools. She is very happy. She studies in a school specially for migrant workers’（外来务工人员的）children. For children like Li Xin who don’t have enough money, these free schools are their best choice, because they have free classes, textbooks, uniforms and meals in the schools.
    But there is a long way to go. The free schools for children from migrant workers’ families are not enough because to run such a school is not easy and needs lots of money. A school officer said they needed at least one million yuan to run the school. “Luckily, some people and companies donate（捐赠）money, used books and a lot of other things to help us. There are also some volunteers teachers,” he added.
    Anyhow, we must try to give these children an equal（平等）chance to get better education so that we can make our society harmonious（和谐的）.
    小题1:From the passage, we know that Li Xin’s parents used to be __________.
    A．workersB．teachers
    C．officersD．farmers
    小题2:The school provides Li Xin with the following things free except_____.
    A．textbooksB．uniforms
    C．computersD．meals
    小题3:What does the underlined word “run” mean in Chinese in the passage?
    A．奔跑B．经营C．考虑D．收购
    小题4:The passage mainly talks about__________.
    A．what jobs migrant workers can do in big cities
    B．the development of big cities
    C．helping migrant workers’ children go to school
    D．what difficulties those free schools face now
