Researchers in Britain are driving the environmental movement to a new level. A team from the University of Warwick has built what it calls the world’s first completely environmentally friendly Formula Three racing car.
The car is made mainly of renewable materials, like plants and vegetables. The structure around the car is made from natural plant fibers and potatoes. The steering wheel(方向盘) is made from root vegetables like carrots. The engine uses bio-fuel made from vegetable oil and waste chocolate.
The new racing car is extremely fast. The car has a top speed of two hundred fifteen kilometers an hour. And it can go from zero to ninety-five kilometers an hour in just two and a half seconds. The racing car meets all of the Formula Three racing requirements except for its biodiesel(生物柴油) engine.
Automobile racing is one of the most widely watched sports in the world. But it is also considered one of the least friendly sports to the environment. Racing cars burn a lot of fuel, and create a lot of air pollution. In recent years, the racing industry has taken steps to protect the environment. More racing companies are now producing cars that use less energy. These cars produce less pollution than cars that depend on traditional fuel, like gasoline.
Last month, the new racing car was set to run in its first competitive race at the Formula Three Championship Final at Brands Hatch. It would have been the first biodiesel-powered car to race at Formula Three. Current Formula Three rules let only gasoline-powered car to compete. Officials needed permission from all of the Formula Three racers for the biodiesel-powered car to compete. They were unable to contact one of the drivers, so the new racing car didn’t appear in the event. In test runs, the new racing car was the fifth fastest among the Formula Three race cars. Supporters are hoping to have the fuel problem solved in time to compete in the next season.
【小题1】. What’s the second paragraph mainly about?

Broken rubber bands and flat tires requiring replacement could soon be a thing of the past．

French researchers have developed a new kind of rubber that can repair itself when broken．The new rubber is made from widely available materials including vegetable oil and a common industrial chemical．All the materials are considered safe to the environment and can be easily reused．

The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch．When cut, the rubber can be made new again, simply by pressing the two broken ends back together．

The product can be repaired at room temperature, around twenty degrees Centigrade；other self-healing materials require higher temperatures for repair．

Traditionally, rubber substances are made from huge molecules（分子）connected by strong chemical links, or bonds．The new rubber is made of smaller molecules．The molecules are linked together using hydrogen bonds．When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks（超分子网）．When the rubber is cut, the molecules attempt to connect with whatever molecule is near them．When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new．

However, time is an important element in the process．If the broken ends are not brought together quickly, a repair is not possible．This is because molecules will form bonds with molecules on their own side．The inventors say the surfaces of the rubber can be repaired within a week of being separated．

The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris．The organization is part of France's National Center for Scientific Research．The new material is described in greater detail in the research publication Nature．

The kids at Shute Country Primary School in Devon are surprisingly quiet when it’s time to go home in the afternoon, instead of the usual shouting and running you can hear them asking each other, “ Are the lights all off?”, “Shall we check the taps in case they are dripping （滴水）?”, “How many paper towels did we use today?”
But it’s not unusual here．The kids have declared a war on waste．
“We’ve never made the children do anything,” explains Liz Templar, the school’s head teacher, “they came up with all ideas themselves．They’re doing this because they want to．”
If you take a look around the school you won’t see anything thrown away unnecessarily．Everything is collected and reused, or sent to be recycled．
Shute School started its green_revolution_two years ago．They looked carefully at every party of school life－from the teaching to the cleaning．They looked at the way stationery（文具） was used－especially photocopying, the way cleaning was carried out, and how food was used and wasted!
Even parents were looked at: how many children came in each car? Did they use unleaded petrol? Could they bring more children in fewer cars?
High on the list was the waste of paper．Next came unfriendly cleaning products．Paper towels were replaced with recycled paper．But the hardest thing for the kids was when they found out how much rubbish was created by the chocolate, crisps and other snacks（小吃） eaten at lunch time．Of their own accord（自愿地）, the children gave them up．Now they bring apples and home-made snacks．
The school has its own garden where they grow vegetables and flowers so that they can learn about the environment．They also use this area for their recycling store-large containers to collect aluminum, bottles, plate and fabric（织物）．
Even the school’s play area is made from recycled things．
Since the children started, the school’s heating and lighting bills have fallen obviously and the number of rubbish bags has gone down from seven a week to two or three．
Everywhere in Shute School there are bright posters asking everyone to take their rubbish home, to save energy and paper and to keep the green flag flying．
1．Which of the following best describes the writer’s idea?
A．The pupils at Shute School are fighting against pollution．
B．The pupils at Shute School are learning to save things．
C．The pupils at Shute School have declared a war on waste．
D．The pupils at Shute School have found a way to recycle waste things．
2．We can infer from the text that “green revolution” means _______．
A．beautifying schoolyard    B．activity against waste
C．planting green plants       D．throwing away waste
3．What do the children think creates the most waste?
A．Paper towels． B．Cleaning products．   
C．Snacks．     D．Paper．
