　　下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。

　　第一篇

　　Weaving With Light

　　In the Sierra Madre mountain range of west central Mexico，the native Huichol people live much the way their ancestors did-without electricity.Thats because its too expensive to string power lines to the remote mountain areas where they live.To help support themselves，the Huichol create beautiful artwork.They sell their art in cities hundreds of miles away from their villages.And without electricity-at home or on the road，they can only work during daylight hours. When it gets dark，they must stop whatever theyre doing.

　　Now，a team of scientists，designers，and architects is using new technologies to provide the Huichol with light after the sun sets.The scientists technique involves weaving tiny electronic crystals into fabrics that can be made into clothes，bags，or other items.

　　By collecting the suns energy during the day，these lightweight fabrics provide bright white light at night.Their inventors have named the fabricsPortable (轻便的)Lights.Portable Lights have the potential to transform the lives of people without electricity around the world，says project leader Sheila Kennedy.

　　Our invention，Kennedy says，came from seeing how we could transform technology we saw every day in the United States and move it into new markets for people who didnt have a lot of money.

　　At the core of Portable Light technology are devices called high-brightness light-emitting diodes (高亮度发光二极管)，or HB LEDs. These tiny lights appear in digital clocks，televisions，and streetlights.

　　LEDs are completely different from the light bulbs (灯泡).Most of those glass bulbs belong to a type called incandescent lights (白炽灯).Inside，electricity heats a metal coil (线圈)to about 2，200 degrees Celsius.At that temperature，bulbs give off light we can see.

　　Ninety percent of energy produced by incandescent lights，however，is heat-and invisible. With all that wasted energy，bulbs bum out quickly.They are also easily broken.

　　LEDs，on the other hand，are like tiny pieces of rock made up of molecules (分子)that are arranged in a crystal structure.When an electric current passes through an LED，the crystal structure produces light.Unlike incandescent bulbs，they can produce light of various colors.Within an LED，the type of molecules and their particular arrangement determines what color is produced.

　　31. The Huichol dont use electricity because

　　A. it is too difficult for them to change their lifestyle

　　B. they know nothing about it

　　C. it costs too much to string power lines

　　D. they dont need it

　　32.To make a living，the Huichol create artwork and

　　A.sell it in cities far away from their villages.

　　B.sell it to tourists in their villages.

　　C.display it in their village museum.

　　D.keep it in their homes to attract tourists.

　　33.The central part of the Portable Lights technology is

　　A.Glass Bulbs.

　　B.HB LEDs.

　　C.digital clocks.

　　D.incandescent lights.

　　34. All of the following are disadvantage of incandescent lights EXPECT

　　A. they burn out quickly

　　B. they are easily broken

　　C. they are not bright enough.

　　D. they waste most of the energy produced

　　35.LEDs are different from light bulbs in that

　　A.LEDs can send out light of different colors.

　　B.LEDs are made up of tiny pieces of rock.

　　C.LEDs belong to incandescent lights.

　　D.LEDs look like crystals.

　　The book of life

　　So far, scientists have named about 1.8 million living species(物种), and thats a just a small part of what probably exists on Earth. With so many plants, animals, and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.

　　A soon-to-be-started Web site might help. An international team of researchers has announced the creation of Web-based Encyclopedia(百科全书)of life(EOL). The project aims to catalog every species on Earth in a single, easy-to-use reference guide.

　　To get the encyclopedia started, the creators will use information from scientific databases(数据库)that already exist. And eventually, in special sections of the site, nonscientist with specialized(专门的)knowledge will get to join in. Bird-watchers, for example, will be able to input which birds theyve seen and where. The technology for this kind of tool has only become available.

　　As the EOL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that havent been reviewed.

　　Another convenient feature of the EOL is that youll be able to pick the level of detail you want to see to match your interest, age, and knowledge. If you wanted to learn about bears for a science class report, for example, you could use the novice setting to get basic information about the animals. On the expert setting, on the other hand, you could get much more detailed information about the history, literature, and exploration of bears.

　　It now takes years for scientists to collect all the data they need to describe and analyze species. The creators of the Encyclopedia of Life hope that their new tool will speed up that process.

　　36. Spider and bird mentioned in Paragraph 1 are examples to illustrate

　　A. there are numerous living species on Earth.

　　B. animals are peoples friends.

　　C. it is easy to see spiders and birds.

　　D. there are many types of spiders and birds.

　　37. The goal of the creation of the EOL is to

　　A. collect enough data to analyze the living species on Earth.

　　B. enlarge an existing Web site of the living species on Earth.

　　C. add new information to the existing databases of the living species on Earth.

　　D. work out an easy-to-use catalog of every living species on Earth.

　　38. At the starting stage, the EOL will get information from

　　A. all the Web sites available.

　　B. databases built up by its creators.

　　C. the existing scientific databases.

　　D. nonscientists with specialized knowledge.

　　39. The word novice in Paragraph 5 could be best replaced by

　　A. scientist.

　　B. creator.

　　C. beginner

　　D. expert.

　　40. Which of the following statement is NOT true?

　　A. Scientist will review every piece of information added to EOL

　　B. The EOL will be beneficial to school kids with its development.

　　C. Scientists have cataloged only a small part of the living species on Earth.

　　D. People with different interests and knowledge will in a way find the EOL useful.

　　How To Be A Successful Businessman

　　Have you ever wondered why some people are successful in business and others are not? Heres a story about one successful businessperson. He started out washing dishes and today he owns 168 restaurants.

　　Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, and when he was 16 years old, he learned to fly a small plane.

　　At the age of 23 and with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working for a company that rented cars.

　　While Mr. Kazi was working at the car rental (租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. For two months, he worked as cooks assistant. His job was to clean the kitchen and help the cook. I didnt like it, Mr. Kazi says, but I always did the best I could.

　　One day, Mr. Kazis two co-workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant. A few months later, the owners needed a manager for a new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager and soon the restaurant was making a profit.

If someone had to wait more than ten minutes for their food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.

　　A year later, Mr. Kazi sold his restaurant for a profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, and retrained the employees. Before long these restaurants were making a profit , too.

　　Today Mr. Kazi owns 168 restaurants, but he isnt planning to stop there. Hes looking for more poorly managed restaurants to buy. I love it when I go to buy a restaurant and find its a mess, Mr. Kazi says. The only way it can go is up.
