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.

Do you know that some people don’t do their reading assignments(任务)?It’s shocking , but it’s true . Some students don’t even read short texts that they are assigned in class . There are many reasons for this . They may be unwill ing to focus . They may be unconfident readers . Whatever the reason is , it has to stop today . Here’s why .

Reading stimulates(刺激)your mind . It is like a workout for your brain . When people get old , their muscles begin to weaken and their strength leaves them . Exercise can prevent this loss . The same thing happens to people’s brains when they get older . Brain power and speed decline with age . Reading strengthens your brain and prevents these declines . You can benefit from reading in the near-term , too .

Reading provides knowledge . Knowledge is power . Therefore , reading can make you a more powerful person . You can learn to do new things by reading . Do you want to make video games ? Do you want to design clothing ? Reading can teach you all this and more . But you have to get good at reading , and the only way is to practice .

Reading expands your vocabulary . Read everything that you can at school , no matter whether you find it interesting or not . Even a “boring” text can teach you new words . Having a larger vocabulary will help you better express yourself . You will be able to speak , write and think more intelligently . What’s boring about that ?

Reading can change the way that you understand the word. Do not just discount(忽视) a text because it is unfamiliar to you . Each time you read , you are introduced to new ideas and given broader views on things . You can learn how people live in faraway places . You can learn about cultures different from your own . Reading is good for your state of mind . It has a calming effect . It can lower your stress levels and help you relax . You can escape from your troubles for a moment when you read , and it’s a positive escape.

The benefits of reading far outweigh those of acting like a fool . So do yourself a favor : the next time you get a reading assignment , take as much as you can form it . Squeeze(挤压) it for every drop of knowledge that it contains . Then move on to the next one.
