Part I Reading Comprehension(40%) Passage one

In Labrador, a country so cold that meat is preserved by freezing it outdoors, Clarence Birdseye came to notice that meat which was frozen on the coldest days had a better flavor than meat frozen at other times. Being curious, he studied preserved meats under the microscope and found that if meat were frozen quickly on a very cold day, ice crystals did not have time to form long needles and the meat cells were not damaged.

Birdseye believed that if he could freeze other foods very rapidly, the same thing might happen. But, since there are not many days when the temperature drops 40 or 45 degrees below zero-even in Labrador-some way had to be found to freeze things rapidly without depending on the weather. Remembering that salty water can get very cold without freezing, Birdseye placed some cabbages in salt water and then exposed them to freezing winds. The cabbages froze quickly.

Later, Birdseye invented a machine to freeze food while they were very fresh. Today, stores sell a great variety of frozen foods, and some foods that were once available only in certain districts or in season are now readily available in most communities(社区)in any season. 1.To freeze foods quickly, Birdseye experimented with ______ .

A.a microscope B.meat in salt water C.meat in freezing winds D.cabbages 2.Cell damage is caused by ______ .

A.salty water B.extremely low temperatures C.outdoor freezing methods D.needle-shaped ice crystals 3.Birdseye’s principal discovery regarding food preservation was that ______ . A.rapid freezing would reduce cell damage

B.foods could be frozen and preserved for later use C.salty water can get very cold without freezing D.meat must be frozen at 45 degrees below zero 4.Later, Birdseye invented ______ .

A.a refrigerator B.a machine that would freeze foods quickly C.a machine that would freeze foods slowly D.the icebox

5.Much of the popularity of today’s frozen foods is due to the fact that ______ . A.foods may be widely distributed B.disease can be eliminated

C.every American home has a deep-freeze D.such foods are now considered luxuries Passage Two

Astronomers in California have spent the past decade designing a revolutionary, 10-meter telescope with four times the “seeing power” of any functional scope on earth. All they needed was the money to make the project a reality, and last week they got it- a $70 million grant to the California Institute of Technology and the University of California from the W. M. Keck Foundation of Los Angeles, established by the late founder of the Superior Oil Co. The Keck Observatory, which should be completed by 1993, will be set up on Hawaii’s Manna Kea. Its
