Passage 14

(江西省抚州一中2009届高三第四次模拟考试E篇)

Every day from the time we wake up until the time we go to bed, we are bombarded with information from all sides, from TV, radio, newspapers and books; from family, friends, and colleagues. As a new cable television subscriber, I am absolutely amazed at the quantity and varying levels of information quality on cable television. Including the networks, there are eight TV "news" organizations vying to provide us with all the information we can possibly absorb. Newspaper, magazines, books, radio, the Internet, email, snail mail, and the telephone all compete for our attention and our minds. At the office conversations around the water cooler and coffee maker serve to spread even more items of information. 　There is valuable information out there about the world we live in, on topics as varied as health, safety, traffic, nutrition, business, finance, philosophy, nature, science, weather, history and the human condition. There is also a large amount of misleading and outright false information, not just on controversial subjects such as politics and religion but on any topic one can think of, including all of the topics mentioned above. 　With all this information coming at us from all directions, how does one sift through it all to sort out the facts from the fiction, the truth from the lies, the more important from the less important? Should we turn off the TV, cancel our newspaper subscriptions, disconnect our phones and modems to become information "hermits"? Probably not. 　A better method of sifting through the information wave without being overwhelmed and confused is to become a skeptical inquirer-or skeptic-with regard to the surrounding world. By "skeptic"-I do not mean a cynic-a person who rejects new ideas simply because they are new. A skeptic is one who questions the validity of a particular claim by calling for evidence to prove or disprove it. Skepticism is a method, not a position. It is a provisional approach to all factual claims. In terms of processing information, a skeptic needs to be able to grasp reality and acquire knowledge about the environment that agrees with reason, logic, and evidence. In other words, as skeptics, when we hear a claim that may or may not be fantastic, we should say, "That's nice, prove it."

Passage 13

(江西省抚州一中2009届高三第四次模拟考试B篇)

How many things can you see in the night sky? A lot! On a clearnight you might see the Moon, some planets, and thousands of sparkling stars.

　　　　 You can see even more with a telescope. And with bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more detail.

　　　　 But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year.

　　　　 That's because they're invisible. They're the mysterious dead stars called black holes.

　　　　 You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years.

　　　　 As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die.

　　　　 As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe.

　　　　 Imagine if the Earth were crushed until it was the size of a tiny marble. That's how tightly this dead star, a black hole, is packed. What pulls the star in toward its center with such power? It's the same force that pulls you down when you jump--the force called gravity. A black hole is so tightly packed that its gravity sucks in everything--even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness.

　　　　 So next time you stare up at the night sky, remember: there's more in the Sky than we can see! Scattered in the silent darkness are black holes--the great mystery of space.

Passage 12

(江苏省启东中学2009届高三最后一卷B篇)

When a handheld video game runs out of power, all you have to do is plug it in and charge it up. Within a few years, some of you might do the same thing with mom’s car.

Automobile companies are developing vehicles that will plug into electric sockets (插座), just like many laptops, digital cameras, cell phones and small video game players do. Called “plug-in hybrids (混合动力汽车),” these cars will get most of their power from electricity. Their drivers will rarely have to stop at gas stations.

The technology is more than just cool. In our automobile-filled world, plug-in vehicles could reduce the amount of gasoline we use. That gas is made from crude oil, which has been kept rising in cost. Plus, driving around in these hybrids may even help the environment. Gas-burning cars produce a lot of carbon dioxide, a type of greenhouse gas. These gases stay in the atmosphere, where they trap heat and cause global warming.

The first company-produced plug-in hybrids could hit the roads by 20l0. But engineers still have a lot of work to do to make the technology practical and inexpensive.

Batteries are the biggest challenge. In the plug-in-hybrid world, Li-ion batteries are getting the most attention. These batteries can store a large amount of energy in a small package, and they last a relatively long time between charges. Li-ion batteries are standard in laptops, cell phones, heart devices and similar portable devices.

But because cars are so big and heavy, it would still require a suitcase-sized Li-ion battery to power about l2km of driving. What’s more, the batteries are extremely expensive.

“A car filled with batteries could go a long distance,” says Ted Bohn, an electrical engineer in Chicago. “But it couldn’t haul (拖拉) any people, and it would cost $l00,000.”

So researchers need to figure out how to make batteries smaller and cheaper, among other questions.

“The answers don’t exist yet,” Bohn says. “As a kid I thought someone someplace knows the answer to everything. All of these questions haven’t been decided. That’s what engineering is about - making a guess, running tests and fine-tuning results.”
