A town in Oxfordshire has become the first in the UK to have biomethane（生物甲烷）gas from human waste piped to their homes for gas central heating and cooking.

Up to 200 families in Didcot now receive the gas via the national gas power system. Head of energy and technology at British Gas, Martin Orrill, said customers wouldn’t notice any difference as the gas is purified（提煉）to the highest standard and has no smell. The gas is produced at a sewage（污物）treatment works plant in Didcot.

The entire process takes only less than three weeks, with the sewage being collected and sent first to settlement tanks. The solid waste material is then fed into digesters, where anaerobic bacteria（厭氧菌）digest the sewage, with the aid of enzymes（酶）to speed up the process. The digestion process produces methane, which can be burned to drive machines to produce electricity, or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more efficient since around two-thirds of the energy is lost in producing electricity.

Partners in the Didcot project, British Gas, Scotia Gas Networks, and Thames Water, all hope to expand the process to other towns, and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned. One of these projects, in Manchester, could be supplying 500 homes with biomethane by mid next year. Another British Gas project in Suffolk will provide gas from digestion of brewery wastes to around 235 families.

The Didcot project cost ￡2.5m and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies. An EU directive means the UK must ensure at least 15 percent of its energy is from renewable sources by 2020.

    The UK produces about 1.73 million tons of sewage annually. If all sewage treatment works in the UK were fitted with the technology, they could supply gas for up to 350,000 families.

Which of the following is true of the biomethane gas?

   A. It’s mainly made from rotting plants.

   B. It’s an environmentally friendly gas.

   C. Its production process is too long.

   D. It’s easily recognized by the customers.

What is the function of the enzymes?

   A. To digest the solid waste material.

   B. To help get rid of anaerobic bacteria.

   C. To help purify the biomethane.

   D. To speed up the digestion process.

According to British Gas, the biomethane gas had better be used _____.

   A. as the power for the vehicles                          

   B. for the heating and cooking

   C. to produce the electricity                               

   D. to drive a variety of machines

The last three paragraphs mainly show that _____.

   A. UK government supports the biome thane projects

   B. the biome thane projects are very costly

   C. the biome thane projects still face many barriers

   D. the biome thane projects are promising

What should the text belong to?

   A. Computer science.             B. Engineering.      C. Energy.             D. Business.

(C)                                  
The Romans built great "aqueducts" to carry fresh water from the mountains to the cities. Many of these aqueducts are still standing today. The Romans also built great pipes under the ground to carry away the sewage. In Rome, one of these sewage pipes (sewers) is still used today; it is 2,000 years old. The Roman Emperors even set up a government health service. They built the first great public hospitals in Europe, and they paid doctors to look after poor people.                    
Then the Roman Empire fell to pieces, these civilized methods of treatment disappeared from most of Europe, for more than a thousand years. People went back to the old ways. They lived in dirty conditions which helped to cause diseases（疾病）; and they asked God to cure the disease. They shut mentally sick people in prisons. Or they  burnt them alive because they were supposed to have magic powers.                
But the work of the Greek and Roman doctors was not lost. Over a thousand years
ago, they Arabs moved into many of the Mediterranean countries. They took big parts of the old Roman lands. They translated the Greek and Roman medical books into Arabic. Arab doctors themselves make many new discoveries.
When civilization(文明) at last came back to Europe, men once again translated the Greek and Roman works on medicine into Latin. Slowly－very slowly －European doctors discovered again the things that the Greeks and Romans had known so long ago. Slowly, they began to make new discoveries. They found out more about the way the body works--the way our blood goes round our bodies, the way our nerves（神經(jīng)） send messages from our brains to our muscles, the way these muscles move our bodies.
1.     The word "aqueduct" probably means _______.                                 A. something which was built long ago  
B. something invented by a Roman Emperor
C. a big pipe under the ground        
D. something built to supply clean water for the citizens
2. Which of the following is true?
A. The sewage pipes built by the Roman are no longer in use now.                  B. Sewage pipes in Arabia were built by the Romans.                           C. A sewage pipe still being used today in Rome was built 2,000 .years ago.          D. The ancient Romans got their drinking water from underground pipes.
3. Which of the following is NOT true?
A. A government health service was set up in ancient Rome.
B. The first public hospital in Europe was built in Rome.
C. m ancient Rome doctors were paid by the government.
D. Those who were mentally sick were all burnt alive in the Roman Empire.
4. In this article, "civilized methods of treatment" refers to _______.
A. advanced forms of health care
B. the way they burnt the bodies of the dead
C. imprisonment of the mentally sick
D. what was called magic power's

Heavy downpours last month in Rhode Island led to widespread flooding, causing millions of dollars in property damage and leaving thousands homeless. The flood waters also poured vast amounts of raw sewage(未經(jīng)凈化的污水) into the rivers and streams that flow into Narragansett Bay.

It sounds like the makings of an environmental nightmare. But in fact it’s just the opposite. To scientists’ delight. The sewage-loaded floodwaters have caused a well-timed growth of phytoplankton. The microscopic creatures that form the foundation of marine(海洋的) food chains. With more food available for fish. Clams and other sea creatures. The bay’s fisheries industry is expected to benefit.

In decades past. Narragansett Bay typically experienced a late winter early spring algal(海藻) bloom that fed creatures up and down the water column. But in recent years, the waters of Narragansen Bay warmed greatly, meriting this seasonal event.

Mark Berman, an oceanographer with the Nationa. Marine Fishertes Service. Said the flood seemed to have sent the bay back in its normal state.

However, local, mutate and federal officials in Rhode Island leave been batting other algal blooms that, by contrast, are causing widespread harm to the Narragansett Bay ecosystem. During summer months, sewage and agricultural runnel flows into the bay. Causing large blooms. But inseam of becoming food for sea creatures, much of the phytoplankton is consumed by bacteria, which grow last in the warmer waters. The rapid bacteria growth leads to hypoxia decrease of oxygen in the water that can cause large fish tools. One such die-off occurred in 2003. when millions of oxygen-starved fish washed up on the belches of Narragansett Bay.

The flood’s positive impact will probably be a one-time event, Mr Berman said. Mcanwhile efforts to curb the harmhl summer honors continue; in 2003. for instance, Providence completed a $359 million sewage tonal under the city designated to reduce the polluted storm overflow into Narragansett Bay.

71．Scientists believe that the row sewage flowing into the bay will           .

A．pollute the island’s environ mean   B．cause lots of property damage

C．increase the fisheries production     D．destroy the food chains in the bay

72．The potential benefit of fisherics industry rclics on the           .

A．pollute the local natural environment

B．increase the prcducmon of fishery industry

C．cause large fish kills of the bay indirectly

D．provide too much food ior sea creatures
