As the world 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 percent 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 them 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. It 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.

Rethinking on Sorting of Waste
Waste sorting is becoming increasingly common around the world.It has slowly moved into the center of discussion on the future of business and sustainable(可持续的) development.It may seem like a tiny activity, but is indeed quite complex.Waste sorting is no doubt an important step toward a global circular economy(循环经济) and an environment-friendly society.
In the coming years, the world is supposed to clear out the use of fossil fuels(化学燃料), become more resource- efficient and ensure greater equity(公平).Waste sorting can play a key role in achieving these goals. However, what we need and expect is very different from what we are taking now.Waste sorting in some areas is working reasonably well, for example the glass and metal industries.But when we are looking at global sustainability, there is a need to rethink waste sorting.
The world seems to be in a dilemma.It is no longer clear if the kind of waste sorting done in western nations is part of the problem or the solution.Much of the recycled waste is turned into low-value goods in a way that does not result in a completely reduced use of natural resources.People around the world have begun to realize that much of the waste they sort is not perfect in sustainable material flows.Instead, it is shipped to poor countries, without being used in a correct way.
A waste sorting system for the 21st century should build on the high technology that allows citizens to know more about what is happening to the waste they are sorting.It should also require companies to show how resources-efficient their solutions are In this way, consumers(消费者)will be able to compare choices.
China could start in the next generation of waste sorting systems- those that help citizens to know more about what is happening to the waste they are sorting.Such a waste sorting system would be a driver for innovation and resource efficiency and a true step toward a greener global village.
1.The author leads in the topic “waste sorting” by__________.
A.introducing the steps to do it B.comparing the laws on it
C.listing different ideas about it D.presenting the importance of it
2.The author says “The world seems to be in a dilemma” to show that__________.
A.new resources need to be discovered B.the circular economy should be questioned
C.waste sorting in western nations is not perfect D.recycled waste shipped to poor countries is useless
3.What can we learn about the waste sorting system for the 2lst century?
A.Recycled waste must be turned into high-value goods.
B.Consumers can suggest the best way to sort their garbage.
C.High technology may help to improve the resource efficiency.
D.Companies should spend most of their money on new technology

As the world's population continues to increase, so does the amount of global waste people produce. According to data collected by the World Bank Group, nations are on pace to produce 4 billion tons of waste every year by 2100. Many experts are calling the problem of global waste a worldwide health crisis(危机)because it is ruining the world's oceans, air and soil and endangering the health of all living things.
For years, governments have been telling people that living a zero-waste lifestyle is the way to go. One example of this is what's often called the three R's: reduce, reuse recycle. In that case, less money is spent on waste management. Such positive effects on an economy(经济)as a result of applying the basic rules of reduce, reuse and recycle-is known as a circular economy.
Now some stores are helping people do that. Sometimes, grocery stores produce waste when they throw away food including fruit and vegetables that don't look good any more.In other cases, it's packaged food that is nearing the "sell-by" date printed on the package which is not considered safe to eat. To solve this problem, business people are opening smaller zero-waste stores. Instead of selling food in packages, these stores offer it in open containers. Customers bring their own bags or clean containers to the store. There, they fill their bags or containers with everything from nuts and rice to oil and sauce. They pay for only the amount of each product that they need. Zero-waste stores often sell fruit and vegetables as well. When these goods start to look old, they're sold at a discount or donated to a charity Inspired by these smaller zero-waste stores, some large supermarkets are taking similar steps to reduce the amount of waste that they produce.
By following a circular system, more products than ever are being produced using recycled materials. For example, used tires(轮胎)can be recovered to pave roads, while plastic is reused to make new plastic products. Environmentally-friendly decisions like these help to protect and save natural resources, reduce pollution, save landfill space and even create new job opportunities. Recycling can truly turn garbage into gold.
1.What is the main purpose of the first paragraph? ______
A.To explain the experts' opinion.
B.To discuss the reason of the problem.
C.To draw people's attention on the problem.
D.To introduce a research of the World Bank Group.
2.We can infer from the passage that ______.
A.grocery stores sell bad-looking food cheaper
B.some supermarkets will sell food without packages
C.governments decided to spend less money on recycling
D.customers will pay for the containers in zero-waste stores
3.Which of the following would be the best title for the passage?
A.Zero Waste, Full Recycle.
B.Less Garbage, More Gold.
C.Global Waste, a Worldwide Crisis.
D.Zero-waste Stores, Garbage Killer.

Zongzi is a traditional Chinese food. In the Western world, it is also known as rice dumplings. It is traditionally eaten during the Dragon Boat Festival which falls on the fifth day of the fifth month of the lunar calendar.
A popular belief about the festival is the death of Qu Yuan. He is a famous Chinese poet from the kingdom of Chu. When his country was defeated by the kingdom of Qin, Qu Yuan was so hopeless that he drowned himself in the Miluo River. According to the legend, people threw rice into the river to stop the fish from eating the poet’s body.
There are many kinds of shapes about zongzi. Making zongzi is a skill that is passed down through families. It is also a traditional family event that everyone will be interested in.
The fillings used for zongzi are different from region to region, but the rice used is almost always the sticky rice. Depending on the region, the rice may be lightly cooked or soaked(浸泡) in water before being used. In the north, fillings are mostly red beans and red dates(红枣).
In the past, zongzi was made only once a year on the Dragon Boat Festival, but now it is quite different. People can eat zongzi at any time of a year. And we can find all kinds of zongzi at traditional markets.
