Boys and girls,

May I have your attention, please? Now I¡¯d like to make a speech here.

Nowadays, some of us students have formed some bad habits on campus. For example, some students leave lights on during the day time, or let water running after washing. Some leave over food on the table after eating. Besides, waste paper and spoiled books can be seen everywhere. As we all know, these bad habits will have a bad influence on our character and behavior. What¡¯s more, they can not only increase our cost and add financial burden to our parents, but also waste the limited resources.

Dear friends, we should start with ourselves to save everything. We should try every possible means to change the present situation.

That¡¯s all. Thank you.

A town in Oxfordshire has become the first in the UK to have biomethane£¨ÉúÎï¼×Í飩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£¨ÌáÁ¶£©to the highest standard and has no smell. The gas is produced at a sewage£¨ÎÛÎ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£¨ÑáÑõ¾ú£©digest the sewage, with the aid of enzymes£¨Ã¸£©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 ¡ê2.5m 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.

There¡¯s an old man in our village calling Old Joe who said to be 110 years old. This can¡¯t

be proved though he doesn¡¯t have a birth certificate. All his personal papers were destroy

during the World War ¢ò.I don¡¯t know if he really is so old, and it doesn¡¯t matter. He certainly

looks very old. Of course, he is often asked question by people who want to be told the secret

of long life. Old Joe always answered them like this, ¡°If you are offered a cigarette, never

accept it; if you are annoyed by someone, never lose his temper; and if you are asked foolishly

questions, never answer them.¡±
