Section B (10 points)

Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit

What is eBay? The simple answer is that it is a global trading platform where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods. Including cars, movies and DVDs, sporting goods, travel tickets, musical instruments, clothes and shoes---the list goes on and on.

The idea came from Peter Omidyar, who was born in Paris and moved to Washington when he was still a child, at high school,he became very interested in computer programming and after graduating from Tuft University in 1988, He worked for the next few years as a computer engineer. In his free time he started Bay as a kind of hobby, at first offering the service free by word of mouth. By 1996 there was so much traffic on the website that he had to upgrade and he began charging a fee to members. Joined by a friend, Peter Skill, and in 1998 by his capable CEO, Meg Whitman, he has never looked back. Even in the great.com crashes of the late 1990s, eBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the Internet.

EBay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is to take an e-photo, write a description, fill out a sales form and you are in business; the world is your market place. Of course for each item sold eBay gets a percentage and that is a great deal of money. Every day there are more than sixteen million items listed on eBay and eighty percent of the items are sold.

1.According to the passage, what is eBay? (no more than 6 words)

2.How does eBay make money from its website? (no more than 10 words)

3. From the underlined sentence “he has never looked back”, what can we learn about Peter? (no more than 11 words)

4. What do you need to do if you want to start your business on eBay? (no more than 14 words)

   For years scientist have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more    41    than the air outside. It may be one hundred times worse.

   Indoor air pollution can cause a person to feel tired, to    42     eye-pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists    43    that every modern house has some kind of indoor pollution. People began to    44    the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that    45    the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to    46    harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control    47    for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen    48    its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each    49    different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.
