　　A deal has been signed to turn by-products from a Scottish distillery（酿酒厂）into fuel for cars. 

　　In what is declared to be a world first, the Tullibardine distillery in Perthshire has linked up with a spin-out company from Napier University in Edinburgh. They plan to use bacteria to feed on the "leftovers" from the whisky（威士忌酒）making process. This will produce butanol which can be used to fuel vehicles.

　　More than 90% of the stuff that comes out of a whisky distillery is not whisky. It is leftovers like draff and pot ales（酒糟）— both produced in the early stages of the process. They are high in sugar and are currently used for things like fertiliser and cattle feed. Napier University's Biofuel Research Centre (BfRC) has already shown that the right bacteria can feed on those by-products to produce butanol—a direct replacement for vehicle fuel. Now the spin-out company, Celtic Renewables, and independent whisky producer Tullibardine have signed an agreement. Together they will apply the process to thousands of tonnes of the distillery's leftovers. 

　　Professor Martin Tangney, founder of Celtic Renewables, said "Our partnership with Tullibardine is an important step in the development of a business which combines two important Scottish industries — whisky and renewables. This project shows that creative use of existing technologies can utilise resources on our doorstep to benefit both the environment and the economy."

　　Douglas Ross, managing director of Tullibardine, which spends ￡250,000 disposing of its by-products every year, said "We are delighted to be partnering Celtic Renewables in this creative business, the obvious benefits of which are environmental. It takes a cost to us and turns it into something that has social as well as commercial value."

　　The project is being supported by a grant（拨款） from the Scottish government's Zero Waste Scotland initiative. Celtic Renewables said it eventually aimed to build a processing plant in Scotland, with the hope of building an industry that could be worth ￡60m a year.

　　　The discovery of the one of the world’s oldest shipwrecks（沉船）shows that European trade was thriving even in the Bronze Age, according to experts.

　　　The ship, carrying copper and tin ingots（铸块）used to make weapons and jewelry, sank off the coast near Salcombe in Devon and is thought to date from 900 BC. But it was only last year that the South West Maritime Archaeological Group, a team of amateur archaeologists, brought its goods to the surface. The discovery was not announced until this month’s International Shipwreck Conference, in Plymouth, Devon.

　　　It is thought that the goods — 259 copper ingots and 27 of tin — were collected from several different sources in Europe. The discovery shows the high level of maritime（海上的） trade in Europe had reached, even in ancient times. A bronze sword and three gold wrist bracelets were also found at the spot, not far from the famous Salcombe Cannon wreck, which was discovered in the 1990s.

　　The team have not found any of the new ship’s actual body which is thought to have been completely damaged. However, it is likely to have been powered with paddles and had a crew of around 15. The nearby 17th century Salcombe Cannon wreck, which is protected, has produced Europe’s largest collection of 17th century Moroccan gold coins. Another ship dating back to the Bronze Age had earlier been discovered in Salcombe but produced up only 53 artifacts.

　　　The British Museum is due to take charge of the goods and has them valued before giving the team a sum. Experts at the University of Oxford are analyzing them to establish its exact origins. Ben Roberts, a British Museum Bronze Age expert, said, “It is an exciting find. What we have here is really, really good evidence of trade. It is very possible there were also animals and people going across the Channel too. We hardly ever get to see evidence of this cross-Channel trade in action.”

48．The people who first carried the copper and tin ingots to the ship_______.

　　A．died in the ship                   B．came from Britain 

　　C．were good at making money        D．lived about 3,000 years ago

49．From the passage we can learn that ________.

　　A．people in the Bronze Age knew how to trade with other people

　　B．people in the Bronze Age could not make weapons and jewelry

　　C．the copper and tin ingots were used to make ships in the Bronze Age

　　D．there is no doubt that animals went across the Channel in the Bronze Age

50．What did people discover from the famous Salcombe Cannon Wreck?  

　　A．259 copper ingots and 27 of tin.

　　B．Paddles used to power the great ship.

　　C．A bronze sword and three gold wrist bracelets.

　　D．Europe’s largest collection of 17th century Moroccan gold coins.

51．According to the passage, the South West Maritime Archaeological Group________.

　　A．has found the ship’s actual body

　　B．will be paid for what they found .

　　C．announced their discovery after they found the goods

　　D．discovered another ship dating back to the Bronze Age
