[单项选择]If the Federation of American Scientists made a list of educational video games, you might expect to find Oregon Trai, the Story of Conestoga Wagons Trekking into the American West, or the geography favorite Where in the World Is Carmen Sandiegol And don’t forget Half-Life 2. That’s the one where you burn alien zombies to death with exploding barrels of fuel.
OK, that’s exaggerating—but only a little. Where parents see hours wasted in front of a screen, these scientists see potential. An FAS study released this week, titled "Harnessing the Power of Video Games for Learning," reports that best-selling games are built in surprisingly pedagogical ways. Players improve at their own pace. Beating a level requires experimentation, failure and learning from mistakes. Most new games can be played online, requiring collaboration and leadership. Game play is precisely calibrated to balance challenge and progress. It’s a stark contrast to a typical classroom in which one teacher tries to eng

Up to the present, many scientists have made great contributions to the understanding of the universe.
One of them is Albert Einstein, a German physicist, who revolutionized our concepts of space and time with his theories of relativity. In 1905 Einstein published his special theory of relativity. The foundation of the theory is the observation that light moves at a constant speed as measured by all observers, whatever its state of motion. One consequence is that measurements of distance and time are not absolute quantities but very relative to the motion of an observer. Another is that energy(E) can be converted into mass(m), and vice versa, according to the formula E=mc2 ,where c is the speed of light. Ten years later, Einstein’s general theory of relativity extended this work to include acceleration and gravity — stating that the two are equivalent. Einstein showed that gravity is actually the warping of space by matter. One consequence is that l
[单项选择]Should anyone much care whether an American boy living overseas gets six vicious thwacks on his backside So much has been argued, rejoined and rehashed about the case of Michael Fay, an 18-year-old convicted of vandalism and sentenced to a caning in Singapore, that an otherwise sorry little episode has shaded into a certified International Incident, complete with intercessions by the U. S. head of state. An affair has outraged American libertarians even as it has animated a general debate about morality East and West and the proper functioning of U.S. law and order.
Which, to all appearances, is what Singapore wanted. The question of whether anyone should care about Michael Fay is idle. though Singapore officials profess shock at the attention his case had drawn, they know Americans care deeply about the many sides of this issue. Does a teenager convicted of spraying cars with easily removable paint deserve half a dozen powerful strokes At what point does swift, sure punishment be
A. His case captured worldwide attention.
B. He received severe punishment.
C. His experience was out of the ordinary.
D. He was likely to be disabled.
