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.

1.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.

2.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.

3.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

4.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

5.What should the text belong to?

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

If you are in a town in a western country, you'll often see people walking with their dogs. It is still true that a dog is the most useful animal in the world. But the reason why one keeps a dog has changed Once upon a time, a man met a dog and wanted it to help him in the fight against other animals, and he found that the dog listened to him and did what he told him to. Later people used dogs for the hunting other animals, and the dogs didn't eat what they got until their master agreed. So dogs were used for driving sheep and guarding chicks. But now the people in the towns and cities do not need dogs to fight other animals. Of course they keep them to frighten thieves, but the most important reason is that people feel lonely in the city. For a child, a dog is his best friend when he has no friends to play with. For a young wife, a dog is her child when she doesn’t have her own. For old people, a dog is also a child when their real children have grown up and left. Now people do not have to use a dog, but they keep it as a friend, just like a member of the family.

Are you fond of tomatoes? Bunol, a town in Spain, held its yearly tomato festival on the last Wednesday of August. Thousands and thousands of people made their way from all corners of the world to fight in it, the world’s biggest food fight. Tons of fully-grown tomatoes were thrown in the streets.

No one knows exactly how this event started. Maybe it came from a local food fight between friends, or a joke that was played on a bad musician.

On Wednesday, at 11am, the fight began. A cannon(大炮) shot was fired to start the fight. At first, people fought one another, but slowly they began to fight in groups. After exactly one hour, the fight ended when the cannon shot was fired once more. At this point, no more tomatoes could be thrown.

Those who attend this event are encouraged to wear protective glasses. And they must press the tomatoes before throwing so that they won’t hurt others. Another rule is that no one is allowed to take anything — such as a glass bottle — into the fight. Although it is forbidden to tear(扯破) another person’s clothing, the crowd seems to tear the shirt of any clothed person, whether they are men or women.

Fire trucks are used to clean the streets after the fight with water provided from a Roman channel (海峽). The government seems more concerned with cleaning up the town than the visitors, and people go to the Bunol River for a wash.

What do we know about the tomato fight?

A. Nobody knows how it really started.

B. Only people from Spain can take part in it.

C. It is held on the first Wednesday of August.

D. Green tomatoes can be used in the fight.

When the cannon shot is fired the second time, ____.

A. people start to throw tomatoes

B. people start to fight in groups

C. the whole tomato fight is over

D. the fight has lasted for two hours

Which is NOT one of the rules of the tomato fight?

A. People can’t use glass bottles.

B. People must wear protective glasses.

C. It isn’t allowed to tear other people’s clothes.

D. Tomatoes should be pressed before they are thrown.

After the tomato fight, the town government ____.

A. provides water to the people

B. cleans up the streets with fire trucks

C. takes people to the Bunol River

D. holds other activities about tomatoes

第三部分閱讀理解（共20小題；每小題2分，滿分40分）

閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)，并在答題卡上將該項(xiàng)涂黑。
A
As Christmas approaches, towns and cities around the UK are preparing for a very British celebration．
The switching on of a town' s Christmas lights has become an increasingly competitive event over the years, with some councils （會(huì)議） spending lots of money to attract A-list famous persons to do the honors．
The American singer Mariah Carey flew to London in November to switch on the lights at one of the city's biggest shopping centers, while Jim Carrey lighted Oxford Street and promoted his new film at the same time．
Traffic in the historic English city of Bath was brought to a halt as thousands of fans crowded to see the Hollywood actor Nicolas Cage conducted the switching-on ceremony．
Some celebrations do not go according to the plan, as was seen in Birmingham when dozens of people were injured as the famous British boy band JLS took the stage．
Not all towns can afford to bring in an internationally-known star, so many switchon ceremonies are handled by ex-TV talent show competitors．
Pantomime （圣誕童話�。� stars are also much in demand at this time of year, as they aim to promote their Christmas shows．
But if your council hasn't got the budget to bring in a famous face, what are the cheaper alternatives?
A town in the west of England chose to let the public decide by giving their suggestions online．The result: a 21-year-old DIY store worker was given the honor．
"I was amazed and delighted to be asked," said Scott Parker, "it's just a special gift and not something I'd, ever thought about before．"
56．According to the passage, what kind of special celebration can you see at Christmas in UK?
A．People meeting their favorite stars and getting special gifts．
B．Well-known persons invited to make a performance in public．
C．A-list persons lighting Oxford Street and promoting their films．
D．Switching-on ceremonies that are conducted by honored persons．
57．The underlined word "halt" in Paragraph 4 probably means "______" ．
A．start  B．stop              C．ban       D．run
58．Which of the followings can be learned from the passage?
A．Mariah Carey is invited to Bath to switch on the lights．
B．Pantomime stars rarely appear at events like this．
C．Not all those who switch on the Christmas lights can make lots of money．
D．Average persons can not get a chance to switch on the Christmas lights．
59．The following are famous persons EXCEPT _____．
A．Scott Parker      B．Mariah Carey         C．Nicolas Cage       D．Jim Carrey
