There would probably have been other successful commercial growers before Fish if Florida had not been under Spanish rule for some two hundred years. Columbus first brought seeds for citrus trees to the New World and planted them in the Antilles. But it was most likely Ponce de Le6n who introduced oranges to the North American continent when he discovered Florida in 1513. For a time, each Spanish sailor on a ship bound for America was required by law to carry one hundred seeds with him. Later, because seeds tended to dry out, all Spanish ships were required to carry young orange trees. The Spaniards planted citrus trees only for medicinal purpose, however, they saw no need to start commercial groves because oranges were so abundant in Spain.
What is the main topic of the passage？
A．The role of Florida in the American Revolution
B．The discovery of Florida by Ponce de Le6n in 1513
C．The history of the cultivation of oranges in Florida
D．The popularity of Florida oranges in London in the 1770's
【C1】
A．taken
B．pieced
C．kept
D．made
The process described by John Rogers and his colleagues from Bell Laboratories, an arm of Lucent Technologies, in New Jersey, and E Ink Corporation, in Cambridge, Massachusetts, starts with E Ink's established half-way house towards true electronic paper. This is based on spheres containing black, liquid dye and particles of white, solid pigment. The pigment particles are negatively charged, so they can be pushed and pulled around by electrodes located above and below the sheet.
The electrodes, in turn, are controlled by transistors under the sheet. Each transistor manipulates a single picture element (pixel), making it black or white. The pattern of pixels, in turn, makes up the picture or text on the page. The problem lies in making the transistors and connections. Established ways of doing this, such as photolithography, use silicon as the semiconductor in the transistors. That is all right for applications suck as pesters. It is too fragile and too expensive, though, for genuine electronic paper—which is why cheap and flexible electronic components are needed.
For flexibility, Dr. Rogers and his colleagues chose pentacene as their semiconductor, and gold as their wiring. Pentacene is a polymer whose semiconducting properties were discovered only recently. Gold is the most malleable metal known, and one of the best electrical conductors. Although it is pricey, so little is needed that the cost per article is tiny.
To make their electronic paper the researchers started with a thin sheet of Mylar, a tough plastic, that was coated with indium-tin oxide (ITO), a transparent electrical conductor. To carve this conductor into a suitable electric circuit, they used an innovation called microcontact printing lithography. This trick involves printing the pattern of the circuit on to the ITO using a rubber stamp. The "ink" in the process is a solvent-resistant chemical that protects this part of the ITO while allowing the rest to be dissolved.
From the first paragraph of the passage, we can learn that an electronic display ______.
A．can be made as good as paper
B．is cheap enough to be pasted on to walls and billboards
C．will be as thin and flexible as paper
D．is difficult to be created in the form. of flexible electronic circuitry
______ great was the destruction that the South took decades to recover.
A．Very
B．Too
C．So
D．Such
For decades, transport planners have been demanding that motorists should pay directly for the use of roads. According to the professionals, it is the only way of civilizing cities and restraining the growth of inter urban traffic. Politicians have mostly turned a deaf ear, fearing that charging for something what was previously free was a quick route to electoral suicide. But London's initiative suggests that the point where road pricing becomes generally accepted as the most efficient way to restrain traffic is much nearer than most drivers realize.
The mayor of London, Ken Livingstone, has pinned his political reputation on the scheme's success. If it works, cities around the world will rush to copy it. If it fails, he will be jeered from office when he seeks re-election in 2004. But how will success be judged？ The mayor claims that congestion charging will produce ￡130m in net annual revenues, reduce traffic in central London by 15% and reduce traffic delays by about a quarter. Unfortunately these ambitious targets are unlikely to be met.
For a start, the low level at which the charge has been set owes more to politics than traffic planning. Its impact, modest in comparison with the already high ￡4 an hour on-street parking charges in the area, may be less than anticipated. But most transport experts are cautiously optimistic that it will help improve the capital's chaotic transport system. As for the mayor, his political prospects look good. Those who drive cars in the center of London during the day are a tiny fraction of the millions who walk or use public transport to get to work.
London's willingness to take the plunge has moved congestion charging from the realm of transport planners into mainstream politics. Yet the low-tech solution it has adopted has been overtaken by modern microwave radio systems allowing cars to communicate with roadside charging units. The next generation of technology will use global positioning satellites (GPS) to track the position of vehicles wherever they are, on a second-to- second basis.
The brave new world of paying as you go is not far away. For those who drive in rural areas, the cost will come down. But for motorists who spend most of their time in congested urban areas, travel is rightly going to become much more expensive.
We can learn from the first paragraph that in the world the scheme of tolling systems is
A．out of the question.
B．anything but new.
C．for the sake of safety.
D．nowhere near success.
