"With the price of gasoline and with the problems with clean air, it's important we get electric vehicles out on the road."
On California roads there are about two thousand electric cars. By 2003, ten percent of all new cars may be required to have zero emissions. This is a mandate automakers say it is way ahead of its time.
Gloria Bergquist of the Alliance of Auto Manufacturers says, "The technology (for zero emissions) isn't here yet; it still needs advancement in driving range to make it more appealing to a wider consumer audience".
Automakers blame it on the batteries. Power runs out on most cars after about 70 miles. However, some cars can now go more than 100 miles on a charge. Batteries are expensive. Carmakers say there is nothing they can do about it.
Tim Carmichael of the Clean Air Coalition says, "The automakers have not built a vehicle unless required to do so, so it's very important for the state to stay committed to this program requiring automakers to build small amounts in beginning years and then the market will take off".

Mountain climbers around the world dream about going up Mountain Everest (珠穆朗玛峰) . It is the highest mountain in the world. But many people who have climbed the mountain have left waste material that is harming the environment.
A team of Americans is planning the largest clean-up effort ever on Mountain Everest. They will make the risky trip up the mountain next month.
The team of eight Americans will be guided by more than twenty Sherpas of Nepal (尼泊尔夏尔巴人).Their goal is to remove all the trash they see. They will spend two months cleaning up the mountain by gathering oxygen bottles, fuel containers, batteries, drink cans, human waste and other kinds of trash. They are expected to remove at least three tons of trash in large bags.
Team leader Robert Hoffman is making his fourth trip up the mountain. He says he hopes to bring Everest to the condition it was in before the first successful climb fifty years ago. He says he hopes the effort will influence other people to clean up the environment closer home.
Human waste on Everest is a major concern. So the clean-up team will take along newly development equipment to collect and treat human waste. Over the years, the waste articles have polluted the mountain. In the warm season when the ice melts, the polluted water flows to Nepali villages below. The problem has gotten worse in recent years because climbing Everest has become more popular.
When those Americans are planning the trip up Mountain Everest, they are concerned about______.
A.the success in climbing up the mountain
B.the environment pollution of the mountain
C.the equipment for their trip to the mountain
D.the risks facing the mountain climbers

In Copernicus'time people still believed that all things—the sun, the stars, and the planets moved around the earth. It was an old belief that few men had ever questioned. Aristotle had based his theory of astronomy on this belief. Because the Church had long been the center of learning, the theory was also linked to religious beliefs.
In 1506 Copernicus returned to his homeland. A few years later he began to work for the Church. All those years Copernicus carried on his work in astronomy. He had just the most basic equipment and, like other scientists of his day, made observations with only his eyes. Still, using mathematics and logic, Copernicus worked out a different theory, which held that the planets went around the sun.
Copernicus did not announce his ideas. He did not want to make trouble. But he could not hide the scientific truth. So he talked about his theory with his friends, who strongly advised him to have his work published. His great book, on the Revolutions of the Heavenly Bodies, appeared at the very end of his life. Copernicus saw the first copy on the day he died, May 24, 1543.
Which of the following is true about Copernicus?
A.He had two brothers and a sister.
B.He used to be called Niklas Koppernigk.
C.He lost his father soon after he was born.
D.He spent 10 years at the University of Cracow.
