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（提炼）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（厌氧菌）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.
【小题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. |
| 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. |
| 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 |
| 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 |
| 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.

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 (海峡). 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
