| Fast driving is always dangerous. Motor-racing is even more dangerous. But have you ever heard of motor-racing which is noisy, fast, exciting and safe? No? Then perhaps you have never heard of karting, also sometimes called go karting. A kart is rather like a baby car with no roof. It has a small engine, 4 small wheels and room for only the driver. Its top speed is about 80 kilometers per hour. Karting clubs are private and young people under the age of 17 can be members. On the private land of the club, they can go karting. Some secondary schools think karting is very good for their pupils. The pupils can make everything except the engine and the tyres at school. Tyres for kart are not very expensive. An old motorcycle engine does not cost much and is good enough as a kart engine. The pupils enjoy studies which are part of real life. The school likes karting for another reason. The sport is safe. Because the karts are low to the ground, serious accidents almost never happen. Karting is something new and exciting for these lucky pupils. It also teaches them a lot of engineering. Perhaps they will be better drivers in later life. They may not want to behave (行为举止) like racing-drivers on our dangerous roads. 1. The writer thinks that motor-racing is usually_____________. A. exciting, but quiet B. hard, but interesting C. good for children D. likely to cause danger 2. What is right about a kart? ( ) A. It's drawn by horses. B. It has four great wheels. C. Its high speed is 80 km per minute. D. It has no room for passengers. 3. We have not yet learned from the passage the reason why A. karting is not expensive B. karting lets pupils act like adults C. karting is an exciting sport for pupils D. karting is not a dangerous sport for children 4. How do some schools probably get karts for their pupils? ( ) A. They buy all the new karts at markets. B. They get old automobiles and then repair them. C. They require the children to make karts themselves. D. They receive them from famous clubs. 5. The karting sport is safe because____________. A. the engines of karts are good quality B. the tyres of karts are specially made C. the karts do not run fast D. karts are close to the ground |

The oil resources which are left will not last very long. This means that all vehicles such as cars, trains, buses, planes and ships that need oil to work will not be able to run. So it will be necessary to develop a new system of transport which uses a fuel more than oil. Electric vehicles are one possibility. In Britain, most families have at least one car and this car is used every day. It could be that only one person in the family drives the car to work or for shopping. The number of cars on the road which are almost empty perhaps helps to explain why the oil is used up so quickly. The family car is a very useful form of transport but it is also a great waste of energy, especially if it is compared with buses or trains. Much petrol is used by a car which is traveling at 120 kilometers an hour. Clearly, it would be better if there were fewer cars on the road and more speed limits so that the oil which is left will last as long as possible.
About 25% of Britain’s total consumption of energy is domestic—it is used only in the home. Just over 20% is used for transport. Most of the energy is used in industry. It is difficult to suggest any possible energy conservation in industry because many of the suggestions would mean that some people would lose their jobs. It is important that industry produces the same amount of products using the same amount of workers.
Obviously, conservation is not going to be the answer to the energy crisis（危机）. The most it can do is to give more time for a better solution to be found. The more time which is available for new sources of energy to be developed, the better it is because there is still a lot of work to be done in order to find suitable, safe methods of producing energy.
