Passage One
The first true piece of sports equipment that man invented was the ball.
In ancient Egypt, as everywhere, pitching stones was a favorite children’s game. But a badly thrown rock could hurt a child. Looking for something less dangerous to throw, the Egyptians made what were probably the first balls.
At first, balls were made of grass or leaves held together by vines. Later they were made of piece of animal skin sewed together and stuffed with feathers or hay.
Even though the Egyptians were warlike, they found time for peaceful games. Before long they had developed a number of ball games, each with its own set of rules. Perhaps they played ball more for instruction than for fun. Ball playing was thought of mainly as a way to teach young men the speed and skill they would need for war.

The first balls were probably made of()
A. animal skins stuffed with rocks
B. twists of hay
C. hides stuffed with hay or feathers
D. grass and leaves tied with vines

[简答题] Power Struggle Arnold Schwarzenegger has a mission: he wants to terminate global warming. In June, the California governor called for the state to cut down drastically its greenhouse-gas emissions to 80% of 1990 levels in the next 45 years. "The debate is over," he said in a forthright speech in San Francisco. "We know the science. We see the threat. And we know the time for action is now." This was fighting talk, but if any advanced economy can pull off such drastic cuts in emissions, this high-technology Pacific Rim state and its 36 million residents probably can. Schwarzenegger has help. He gets support from a team of state energy-conservation experts who have been in the business for years. And first among them is Arthur Rosenfeld. More than three decades ago, Rosenfeld helped to trigger the state’’s successful fight to cut energy consumption; today he is one of the five members of California’’s Energy Commission. Rosenfeld spent

For the past several years, the Sunday newspaper supplement Parade has featured a column called "Ask Marilyn". People are invited to query Marilyn vos Savant, who at age 10 had tested at a mental level of someone about 23 years old; that gave her an IQ of 228-the highest score ever recorded. IQ tests ask you to complete verbal and visual analogies, to envision paper after it has been folded and cut, and to deduce numerical sequences, among other similar tasks. So it is a bit confusing when vos Savant fields such queries from the average Joe (whose IQ is 100) as, What’s the difference between love and fondness or what is the nature of luck and coincidence It’s not obvious how the capacity to visualize objects and to figure out numerical patterns suits one to answer questions that have eluded some of the best poets and philosophers.
