But the thing that worries most of us is that we can get viruses from the Internet. But can we catch viruses on our cell phones? A new study in the journal Science says yes, but the spread of such mobile software that can bring harm to our cell phones won't reach dangerous levels until more cell phones are on the same operating system. Computers are easily attacked by viruses because they share data, especially over the Internet. Of course, nowadays, more people are using their cell phones more and more frequently. They use them for emailing, text messaging and downloading troublesome ring tones, etc.,so it is obvious that cell phone viruses are a threat as well. Scientists used nameless call data from more than six million cell phone users to help model a possible outbreak. And they concluded that viruses that spread from phone to phone by Bluetooth are not much concerned, because users have to be in close physical relation for their phones to "see" one another. However, viruses that spread through multimedia messaging services can move much faster, because they can come in disguise , such as a cool tune sent by a friend. The good news is that to be effective, these viruses need their victims to all use the same operating system, which not enough of us do. Because there is no Microsoft operating system for mobile phones, yet. Thank goodness. Question: What is the passage mainly about? Options: A: The operating system of cell phones. B: The threat of cell phone viruses. C: The wide use of cell phones. D: Computer viruses.

Read the article and select the best answer. Article: School violence is in the headlines again after recent shootings at schools in Pennsylvania, Wisconsin, and Colorado. After hearing the news, it's natural for students -- no matter how old they are or where they go to school -- to worry about whether this type of incident may someday happen to them. So how safe are schools? It's actually safer to be in a school than in a car. Twice as many 15-to-19-year-olds die in car accidents than in shootings (and that's all shootings, not just the ones that happen in schools). According to the Centers for Disease Control and Prevention, less than 1% of all homicides among school-age children happen on school grounds or on the way to and from school. So the vast majority of students will never experience violence at school. However, some schools have re-evaluated their safety needs in response to the concerns of families and communities. Some now require that guests check in at the office or have more guards on duty. Some schools have fixed metal detectors. Another thing that helps make schools safer is greater awareness of problems like bullying and discrimination. Many schools have practiced programs to fight these problems and to help teachers and administrators know more about protecting students from this type of violence. The cause of school violence isn't easy to understand. There is no single reason why students become violent. Some are just copying behavior they've seen at home, in the streets, or in video games, movies, or television. There's one thing experts do agree on, though: Having access to guns or other weapons makes it easier for some people to lash out against the things or people they don't like. Question: Which of the following statements can prove that schools are safe? Options: A: About 99% of 15- to-19-year-olds are safe at school. B: Fewer students have died in car accidents than in shootings. C: Students shot to death at school are half of all students. D: Fatal shootings of students are less than 1% of all homicides.

Ques: Read the article and select the best answer. Article: A third of primary schoolchildren in China are suffering from psychological ill-health as a result of classroom stress and parental pressure, according to a study published on Tuesday. The problem is so bad that urgent measures are needed, warns the study, led by British and Chinese researchers. The investigation surveyed 2,191 pupils aged nine to 12 in nine schools in urban and rural Zhejiang, a ly prosperous coastal province in eastern China. Eighty-one percent of the youngsters said they worried "a lot" about exams, 63 percent feared being punished by their teacher, 44 percent had been physically bullied at least sometimes - with boys likelier to be victims than girls - and 73 percent had been physically punished by their parents. Most of the children complained they struggled to cope with the amount of homework they were assigned. Over one-third reported headaches or abdominal pains - psychosomatic symptoms of stress - at least once a week. The most stressed children reported incidence of aches or pains of four times a week. The investigation, led by Therese Hesketh, a professor at University College London (UCL) Centre for International Health and Development, pointed the finger at extreme competitiveness in China's education system, from the onset of primary school. "The competitive and punitive educational environment leads to high levels of stress and psychosomatic symptoms," the authors say. "Measures to reduce unnecessary stress on children in schools should be introduced urgently." The paper appears in Archives of Disease in Childhood, a peer-reviewed journal of the British Medical Association (BMA). The "urban" setting for the study was Hangzhou, the provincial capital of Zhejiang, while the "rural" setting was a poor county in Quzhou prefecture, in the west of the province. The study highlights some of the complexities that, it says, explain the demands for academic excellence and intolerance of failure. One factor is the country's dramatic rise in prosperity, which has created "previously... Question: What can we infer from the passage? Options: A: More and more schoolchildren will drop out of school soon B: Homework and examinations will be cancelled at all schools C: Parents and teachers will give up educating the schoolchildren D: Too much stress does great harm to schoolchildren physically and mentally :
