    　　Children who use mobile phones risk suffering memory loss, sleeping disorders and headaches, according to research published in the medical journal(期刊)The Lancet．

    　　Physicist Dr Gerard Hyland raised new fears over radiation caused by mobile phones and said under-18-year-olds, who represent a quarter of Britain’s 25 million mobile users, were more vulnerable(脆弱)because their immune systems(免疫系统)were less robust．

    　　Radiation is known to affect the brain rhythms(节律)and children are particularly vulnerable．

    　　The effect of microwaves(微波)from a mobile phone is a bit like interference on a radio．It has an impact on the stability(稳定)of cells in the body．The main effects are neurological(神经病学的), causing headaches, memory loss and also sleeping disorders．

    　　He said there was too much uncertainty about the potential(潜在的)dangers of mobile phones．

    　　“If mobile phones were a type of food, they simply would not be licensed(许可)because there is so much uncertainty surrounding their safety, ” he said．

    　　Hyland’s findings came as the government carried out a new task force to study the possible risks of mobile phones．

    　　A government commissioned(政府委托)inquiry into potential risks said in May that children should be discouraged from using mobile phones．

    　　Fresh evidence about the impact of mobile phones on children’s brains follows research in early November showing that hands-free mobile phone kits(用品)can significantly boost(促进)the brain’s exposure to radiation．

    　　Scientists agree that electromagnetic(电磁)radiation from mobile phones warms brain tissue(组织)although it remains unproven that they pose a human health risk．

    　　But Hyland said the real risk was from low intensity(强度)radiation known as non-thermal(热的)radiation, not brain heating．

    科目：高中英语 来源：2013届江西高樟丰宜四校高二下学期期末联考英语试卷（解析版） 题型：阅读理解

    Kelly Reeves was getting ready for a trip when her phone slipped into a sink full of water. Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price.

        A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.

        Fortunately, there’s a solution.

        The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.

        Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.

        Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.

        Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a Web site and see the phone’s location.

        He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety: “60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”

    1.Why does the author mention Kelly’s experience in the first paragraph?

    A. To inform us that mobile phones are useful. 

    B. To introduce the topic for discussion.

    C. To tell us we should get phones ready for a trip.

    D.To warn us that we should be careful.

    2.The underlined word “nomophobia” in Paragraph 2 means ________.

    A. Fear of losing mobile phones.   

    B. Habits of using mobile phones

    C. Independence of mobile phones. 

    D. Eagerness for new mobile phones.

    3.Which of the following is a way to treat nomophobia?

    A. Learning more about modern technology. 

    B. Avoiding using phone for some time

    C. Not using a mobile phone in one’s daily work.

    D. Protecting one’s phone against any damage.

    4.Why can the service called Asurion help to treat nomophobia?

    A. It will give you a new phone through insurance.

    B. It lets you know other people also lose their phones.

    C. It gives you a prescription to treat nomophobia.

    D. It enables you to reconnect with your acquaintance.

    5.What is the passage mainly about?

    A. New mobile phone technology. 

    B. Attitude toward mobile phone.

    C. Solutions to nomophobia      

    D. Disadvantages of mobile phone

    科目：高中英语 来源：河南省2009-2010学年高二校内竞赛试题（英语） 题型：阅读理解

    In the early days of the internet, many people worried that as people in the rich world embraced new computing and communications technologies, people in the poor world would be left stranded on the wrong side of a "digital divide." Yet the debate over the digital divide is founded on a myth that plugging poor countries into the internet will help them to become rich rapidly.

    This is highly unlikely, because the digital divide is not a problem in itself, but a symptom of deeper, more important divides: of income, development and literacy（识字）. Fewer people in poor countries than in rich ones own computers and have access to the internet simply because they are too poor, are illiterate, or have other more immediate concerns, such as food, health care and security. So even if it were possible to wave a magic wand（棒） and cause a computer to appear in every household on earth, it would not achieve very much: a computer is not useful if you have no food or electricity and cannot read. Yet such Wand-waving - through the construction of specific local infrastructure（基础设施） projects such as rural tele-centers--is just the sort of thing for which the UN's new fund is intended.

    This sort of thing is the wrong way to go about addressing the inequality in access to digital technologies: it is treating the symptoms, rather than the underlying（下面） causes. The benefits of building rural computing centers, for example, are unclear. Rather than trying to close the divide for the sake of it, the more sensible goal is to determine how best to use technology to promote bottom-up development. And the answer to that question turns out to be remarkably clear: by promoting the spread not of PCs and the Internet, but of mobile phones.

    1. What is the main idea of this passage?

    A. Plugging poor countries into the Internet will help them to become rich rapidly.

    B. Poor countries should be given more basic devices other than advanced ones.

    C. Rich countries should help poor ones become rich.

    D. People in poor countries cannot afford devices such as computer.

    2. What did the author mean by referring "digital divide." (Line 3, Para. 1)?

    A. Digital technology will make the gap between rich world and poor world wider.

    B. Digital technology will divide people into rich and poor world.

    C. People can be divided digitally.

    D. To divide people in digital world is wrong.

    3. We can infer from the 2nd paragraph that_______.

    A. people in poor countries cannot use computer because of illiteracy.

    B. poor people cannot use computers.

    C. there would be no magic to cause a computer to appear in every household on earth.

    D. people in poor countries need more basic living conditions than computers.

    4. Considering the following sentences, which one would the author most agree?

    A. Digital technology is useless.

    B. Digital divide will help poor countries become rich.

    C. Poor people need more immediate concerns, such as food, health care and security.

    D. Mobile phones should be promoted firstly. 

    5. The following passage will probably be:

    A. How to promote using of mobile phones.

    B. How to use technology to promote bottom-up development.

    C. The benefits of building rural computing centers.

    D. How to meet the need of food, health and security in poor countries.
