Death valley is one of the most famous deserts in the United States, covering a wide area with its alkali(碱性)sand. Almost 20 percent of this area is well below sea level, and bad water, a salt water pool, is about 280 feet below sea level and it is the lowest point in the United States.

    Long ago the Panamint Indians called this place Tomesha—the land of fire. Death Valley’s present name dates back to 1849 when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure ended with a disaster. Today Death Valley has been declared a National Monument and is crossed by several well-marked roads where good services can be found easily. Luckily the changes created by human settlement has hardly ruined the special beauty of this place.

Here nature created a lot of surprising scenes, almost like the sights on the moon, every changing as the frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and variable parts of Death Valley is the Devil’s Golf Course, where it seems hard for one to tell reality from terrible dreams. Sand sculptures(泥雕)stand on a frightening ground, as evening shadows move and lengthen.

1.The name of the valley comes from ________.

    A. an Indian name

    B.the local people

    C.a National Monument

D.the death of the miners

2. From the passage we can learn that ________.

    A. people can find gas stations, cafes and hotels in the desert

    B.no one had ever known the desert before the miners

    C.it’s still not easy to travel across the desert

D.people have changed the natural sights of the desert

Moon landing. The computer chip. Genetic engineering. The artificial heart. The achievements of U.S. scientists are known and admired throughout the world. But whether American highest position in research and technology will continue into the 21st century is far from certain. Thirty-two years after the Russians sent up Sputnik setting off a hot race to produce more and better U.S. physicists, the scientific pipeline is drying up. The reason for this crisis(危机): American science education is in disorder.

    In an Educational Testing Service study of five countries and four Canadian provinces, American 13-year-olds graded last in math and nearly last in science.

How did America, birthplace of Thomas Edison and Wright brothers come to such a dangerous situation? One reason is lack of enough financial support for science education. After Sputnik, funding(基金)for the National Science Foundation, the leading U.S. founder of scientific research, shot up from 18 million dollars to 130 million dollars. By 1982 financing for NSFS education had fallen rapidly to zero.

To be sure, changeable funding is only one reason why U.S. scientists are becoming a scarce commodity(稀有商品). The image of scientists is less lustrous than it was in the 50’s and 60’s when men and women in lab coats were seen as national heroes helping the U.S. beat the Russians to the moon. Today, the country’s brightest desire is to be bankers and lawyers, not chemists or rocket designers.

1.From the passage, we can know that the computer chip, genetic engineering are _______.

    A. examples of American scientific achievements

    B.names of modern technology

    C.seen everywhere throughout the world

    D.obtained by Russia

2.America is losing its highest position in research and technology because _______.

    A. American students are flowing to Canada

    B.men and women in lab coats are seen as national heroes

    C.Thomas Edison and Wright brothers died

    D.financial support for science education is not enough and scientists are less respected

3.According to the passage Sputnik is _______.

    A. a research project of National Science Foundation

    B.the name of an education department

    C.a scientific achievement of Russia

    D.a scarce commodity

4. The word “lustrous” in the last paragraph can be replaced by_______.

    A. difficult

    B.shinning

    C.smart

D.shocking

5.The main idea of the passage is that_______.

    A. America’s leading position in scientific research is in danger

    B.America’s needs more funding in scientific research

    C.the National Science Foundation needs financial support

    D.American students are not good in science

"Earthquake! "The word flashed in my brain. A roaring sound filled my ears. I tried to slide beneath my desk. The desk did a wild tap dance, slipping and sliding towards the center of the room. I twisted my body and grabbed at the windowsill behind me, somehow kicking free of my dancing chair. I tried to stand. My legs skated away as if on a bucking escalator.

   My fingers shaked, grasped and help the windowsill tightly. Somewhere through the roar sounded the terrified scream of some wounded animal. I looked behind me and tried to steady my gaze on the other kids but the scene was a dizzy nightmare. Some of the class were sitting in the middle of the room, surrounded by chairs and desks. One girl was screaming. A boy was trying to claw his way across the floor to the door in a crazy overarm crawl.

   My grip froze me to the windowsill.

   I cried aloud, "I'm going to die. I'm going to die. Save me, I'm not ready to die, I'm not ready!"

   I hunched forward on my knees and pressed my face against my clenched fingers. I looked at the backs of my fingers and stupidly noticed the fragile pale hairs growing out of the pores. The fingers would soon cease to exist. Somehow the impending horror of my death was too terrible to even cry about.

    Suddenly, I became aware that the rocking had ceased. Perhaps I wasn't going to die.

1. The roaring sound was made by ________.

A. a wounded animal

B. people screaming

C. children running

D. an earthquake
