听力原文： It seems like almost everyone buys or sells goods at yard sales in the United States. People place used personal or household goods for sale outside their homes (30) .
The LT. S. one Twenty-Seven Corridor Sale is known as the World's Longest Yardsale. It began in 1987. The event's headquarters is in Jamestown, Tennessee. A former local official, Mike Walker, came up with the idea (31) . He thought it would bring people to the area and show them that small country roads have a lot to offer. Others agreed. They wanted people to consider traveling on these roads instead of the popular interstate system.
Every year, the four-day sale begins on the first Thursday in August. So August 7th of this year marks the opening of the twenty-first World's Longest Yardsale. The event now crosses five states--Ohio, Kentucky, Tennessee, Georgia, and Alabama.
Tens of thousands of sellers take part. Some people who live along or near Route one Twenty-seven simply place their goods for sale in front of their house. Others use nearby public spaces, like parks. People sell everything and anything at the sale: furniture, clothing, toys, books and music. You can also find sporting goods, farm equipment, tools and art. And, lots of other things (32) . Tens of thousands of people from across the country drive along the road in search of interesting things to buy. Route one Twenty-Seven becomes crowded with vehicles.
(31)
A．They are places for people to exchange their goods.
B．They are places for residents to heap the useless things.
C．They are sales set for residents to sell and buy used things.
D．They are sales set by stores to put their goods on sale.
翻译练习（一） Plastics No other material in the history of the world has been used for so many different purposes. But what special qualities do plastics have？ Why do countless people possess so many things made of plastics？ They buy plastic articles because they are not only cheaper but also often much better than articles made of other materials, because their smooth surfaces are so easy to keep clean, because they will not catch fire, and because they are not damaged by water. It is quite extraordinary how many different kinds and qualities of plastics there are. They can be harder than wood or softer than rubber. They can be made so strong that they will last almost forever. They can be made as clean as glass or completely black. They can be made any color you like to choose. They can even be made to look like wood or rubber. The manufacture of plastics requires a large quantity of heavy machines as well as a knowledge of science. Today the greater part of plastics is manufactured by the world's great oil refineries and chemical works. Chemical works are factories which produce chemicals ― a man-made liquids, gases and solid materials. The refineries and chemical works produce many different kinds of raw plastics, which are then taken to the tens of thousands of factories which made plastic products. Machines for making plastic objects are very different from those used for manufacturing articles of wood or metal or other natural materials. For raw plastics must first be softened by heat and then pressed into moulds. It is the moulds which give plastic objects their shapes. These moulds can be of any shape or size. And the same mould can be used over and over again. In fact one mould can produce many thousands of articles before it wears out. This is one of the reasons why plastic things are so cheap.
Fords open policy towards employees ideas "generates tens of thousands of e-mails a month", according to Ed Sketch, the director of training and development in America and Europe. The company has even employed people to sift through them. Money-saving brainwaves are rewarded with big bonuses or a new car.
Companies might want to recruit innovative thinkers, but do they really want nonconformists on board？ Peer Granger, the head of Insight Training, which runs innovation workshops for companies, believes that the risk of not having them on board is greater. "Its not like the old days, where companies could churn out the same old product year after year and customers would buy them. If companies dont innovate, they die. Just look at the high street. And almost by definition, you have to be difficult in order to innovate because it is about challenging the status quo."
The problem is that innovators are usually seen as trouble-makers and are often the first people to go if a company is downsizing. Theres such a blame culture that people are scared to step outside the norms. In our workshops we show people the value of breaking rules."
However, Granger thinks that difficult, innovative people would crumble without their conformist colleagues. "Crikey, you need the other people to say, Hang on, maybe this isnt a good idea, which can save you a lot of hassle later. And turning an idea into reality may involve office politics, which difficult people may not be good at."
The example of the woman whose suggestion was popular indicates that______.
A．everything that is beneficial to people can be said to be innovative
B．even the common people can put forward an innovative suggestion
C．people are easy to accept new things that are helpful to them
D．the ideas from the top sometimes are not as good as those from ordinary people
Questions are based on the following passage.
"Innovative" does not necessarily mean radical or expensive， nor do the best ideas comefrom the top. A woman on the shop floor at Ford suggested putting symbols of different en-gine parts so that drivers would not need a manual to do something simple， such as checkthe oil. It proved so popular it is now common practice.
