Q: Read the article and select the best answer. Article: Forty-two of the fifty American states offered some kind of public online learning this past school year.One state,Michigan,now requires all students to have an online learning experience before they finish high school.Even the idea of a school has changed since the rise ofthe Internet in the 1990s. A new report from the Center for Evaluation and Education Policy at Indiana University says eighteen states have full-time virtual schools.There are no buildings.All classes are online. Florida started the first statewide public virtual school in the United States in 1997.Today,the Florida Virtual School offers more man ninety courses.56,000 students were enrolled as of December.Almost sixty percent were female.The school's website says each student was enrolled in an average of two classes. Florida Virtual School has now opened the Florida Virtual Global School.Students in other countries pay for classes.Janet Heiking teaches an English class.She lives in Indianapolis, Indiana.Her students live as far away as Africa and Japan.She says they are taking her Advanced Placement class to prepare for attending an American college.They can earn college credits by passing the AP test. So how good are virtual schools? Studies have shown mixed results, as a new report from Indiana University notes.For example, students at Florida Virtual School earned higher grades than those taking the same courses the traditional way.And they scored higher on a statewide test.But virtual school students in Kansas and Colorado had lower test scores or performed at a lower level than traditional learners.Studies also find that virtual schools may not save much in operating costs. Education experts say the mixed results suggest the need for more research to find the best ways to teach in virtual schools.A1so, they say schools of education need to train more teachers to work in both real and virtual classrooms. Question: Florida Virtual School is open to _ . Options: A: students in Indiana B: students only around the USA C: students across the world D: only foreign students
A: C

Q: Read the article and select the best answer. Article: The common cold is the world's most widespread illness, which is plagues that flesh receives. The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes. During the First World War soldiers who spent long periods in the trenches , cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp , naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose. If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains--taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on. No one has yet found a cure for the cold. There are drugs and pain suppressors such as aspirin, but all they do is to relieve the symptoms . Question: The writer offered _ examples to support his argument. Options: A: 4 B: 5 C: 6 D: 3
A: B

Q: Read the article and select the best answer. Article: Not very long ago, the question would have seemed absurd. Now it is on the lips of respected scientists; MPs are beginning to talk of "a war on sugar", and even England's chief medical officer has said sugar may have to be, like the old enemy tobacco, taxed in order to protect the nation's health. There came a time in the evolution of public attitudes to smoking, when the doctors had been shouting for long enough that the public was broadly aware of the risks and the only question left,for Government was: what should we do about it? Some believe we are now at the same point in our attitudes to sugar. Others - largely but not only representatives of the food and drink industry - say the entire debate has been skewed, by those who spread stories deliberately to make people nervous. More or less everyone agrees that eating too much sugar is bad for you. There is also no doubt obesity is a growing problem which is putting a significant, avoidable burden on the NHS by increasing the rates of diabetes, heart disease and other long-term conditions. But to what extent is sugar - rather than saturated fats, or salt, carbohydrates or proteins, or any of the other devils of modem diets - the cause of obesity and how much should we worry about it? Yesterday, hopes of achieving anything resembling clarity from the World Health Organisation (WHO) were confused once again, which, widely expected to reduce the recommended sugar intake by a half in new draft guidance, instead said it would continue to recommend that sugar make up no more than 10 per cent of the energy we consume, while adding that cutting this to five per cent would have "additional benefits". The decision will now go out to public consultation. Simon Capewell, professor of the University of Liverpool, said that he suspected "dirty work" on the part of food and drinks companies might lie behind the WHO's less than resounding message. "The food industry say Govemment has no business interfering in families, we must... Question: Which of the following can be the proper title for the passage? Options: A: Is sugar the new evil? B: How much sugar do you take daily? C: Is sugar to be taxed? D: How much do you know about sugar?
