It was Sunday and Tom was staying at home. After breakfast he went out into the garden and played quietly by himself. There were no kids around and he was used to playing alone quietly. He played with Bobby, the dog. He climbed up and down the tree. Sometimes a bird would come down to perch(栖息)on top of the doghouse. Then Tom would have the greatest fun by throwing a stone or something at it. Though he never made it, he did like doing this kind of thing.

Now Tom had been in the garden for half an hour. Suddenly a crack was heard and the little boy began crying.

“What’s the matter, Tom?” His mother looked through the kitchen window. Tom ran into the kitchen.

“Mum,” he sobbed. “I broke Bobby’s plate. I didn’t know it was so fragile(易碎的). His mother put her arms round him and said, “Don’t feel so sad, Tom. We have other plates for Bobby. But how did you break that one?”

“I threw it at a bird but missed, and it went straight to the plate.”

In Tom’s hand was his father’s gold pocket watch!

As the word becomes increasingly populated , It is also Becoming alarmingly polluted . Fortunately , there are many ways that you can help deal with the negative effects that we impose(施加)on the environment . One of these is driving an electric car.

Electric cars produce about 80 pe rcent less pollution than cars with gas-powered motors. In fact, the only reason that electric cars produce any pollution at all is that their electric energy is produced by power plants-electric cars themselves produce no waste. When energy comes from large sources such as power plants, it’s easier to control, so there’s less waste than if the energy is produced by many smaller sources, such as the gas engines in individual cars.

Furthermore, electric cars are simply more efficient than gas-powered cars for several reasons. First, electric cars have regenerative braking, which means that when you use the brakes in an electric car , the battery has a chance to recharge (再充电).On the contrary , when you brake in a gas-powered car ,you actually use energy . Also, during the production of electric cars, more time and energy is spent making the design lighter and more aerodynamic so that there will be less drag(阻力) from the wind. This allows then to travel farther using less energy than a gas-powered car would use to go the same distance.

In addition to the environmental benefits of driving electric cars , there are also financial and time-saving benefits for the drivers . For one , they cost less to maintain (维修). The cost of charging an electric car is about 20 percent of the cost of gas, and electric cars require far less maintenance than gas-powered cars . This is due , in part , to the fact that electric cars have no cooling system , fan belts , radiators , hoses , or oil-just a battery . There are fewer moving parts overall , so there are fewer possible problems . Also , after the body of an electric car gives out , the engine can be reused in another body . Electric cars can also save people time . While gas-powered cars require visits to a mechanic every few months , the only routine maintenance required by electric cars is replacing the battery every four years.

Overall , there are numerous benefits of driving an electric car . Tt may take a little getting used to , but in the long run , the use of electric cars can help preserve the environment and give people more time and money to be put to better use.
