We are all aware of the damaging pollution that’s created by driving petrol and diesel (柴油) vehicles. Many of the world’s cities are blocked with traffic, creating fumes containing gases such as nitrogen oxides. The solution for a cleaner, greener future could be electric vehicles. But how optimistic should we be? There was much excitement last year when the UK government announced it will ban the sale of new petrol and diesel cars from 2030. But is that easier said than done?
The road to global traffic being totally electric is still a long way off. Currently, battery life is an issue — a fully charged battery won’t take you as far as a full tank of petrol. There are also limited numbers of charging points to plug an EV into. Of course, technology is always improving. Some of the biggest tech companies, like Google and Tesla, are spending huge amounts of money developing electric cars. And most of the big car manufacturers are now making them too.
Colin Herron, a consultant on low-carbon vehicle technology, told the BBC: “The big leap forward will come with solid state batteries, which will appear first in mobile phones and laptops before they progress to cars.” These will charge more quickly and give cars a bigger range. Cost is another issue that may discourage people from switching to electric power. But some countries offer incentive, such as cutting prices by reducing import taxes, and not charging for road tax and parking. Some also provide exclusive lanes for electric cars to be driven on, overtaking traditional cars which might be stuck in jams.
These kinds of measures have made Norway the country with the most electric cars per capita (人均) at more than thirty electric cars per 1000 inhabitants. But Colin Herron warns that “electric motoring” doesn’t mean a zero-carbon future. “It’s emission-free motoring, but the car has to be built, the battery has to be built, and the electricity does come from somewhere.” Maybe it’s time to think about making fewer journeys or using public transport.

【推荐1】Insurance companies are starting to use smartbox technology, so good drivers can benefit from cheap insurance rates.
The smartbox, similar to a black box for airplanes, records details about how your car is driven, which can contribute to cheap car insurance for responsible drivers. The device is connected to the electronics in your car and collects information such as time, speed, braking, cornering, acceleration and location. It’s like having an insurance agent sitting beside you while driving.
The smartbox data is wirelessly transferred in real time to the insurance company and provides a profile of when, where and how you drive. This profile is then used to compare insurance rates and to reward low-risk driving behavior with cheap insurance rates.
Drivers are high-risk when they drive irresponsibly such as speeding, frequent lane changing, driving in high-risk locations or at high-risk times such as in heavy traffic or late at night.
These new electronic inventions are intended to practice a new standard in lieu of the previous way to sort drivers into group behavior to determine insurance coverage and premium (保费) payments. For example, young drivers are more likely to drive fast, drive at night and use a cell phone while driving. Statistically, young drivers are more likely to cause an accident, so insurance companies charge them higher rates to cover the costs of accident claims. So even if you’re a young, responsible driver, you will pay high insurance rates because of group behavior. This technology allows you to provide proof that your driving behavior doesn’t fit the pattern of your demographic (统计) group.
All the information collected about your driving can be viewed online — including what you’re doing well and what could be improved. Your insurance premium is then calculated according to your driving profile.

【推荐2】The noise produced by busy roads is a growing problem.
Already, researchers in the Netherlands are working to develop techniques for silencing the roads. In the next five years the Dutch government aims to reduce noise levels from the country’s road surfaces by six decibels overall. Dutch mechanical engineer Ard Kuijpers has come up with one of the most promising and novel ideas. He set out to address the three most important factors: surface texture (质地), hardness and the ability to absorb sound.
The rougher the surface, the more likely it is that a tyre will vibrate (颤动) and create noise. Road builders usually get rid of bumps on freshly laid asphalt (柏油) with heavy rollers, but Kuijpers has developed a method of road building that he thinks can create the ultimate quiet road. His secret is a special mould (模具) 3 metres wide and 50 metres long. Hot asphalt, mixed with small stones, is spread into the mould by a rail-mounted machine which flattens the asphalt mix with a roller. When it sets, the 10-millimetre-thick sheet has a surface smoother than anything that can be achieved by conventional methods.
To better the performance of his road surface—to make it hard wearing yet soft enough to remove vibrations—he then adds another layer below the asphalt. This consists of a 30-millimetre-thick layer of rubber, mixed with stones which are larger than those in the layer above. “It’s like a giant mouse mat, making the road softer,” says Kuijpers.
The foundation itself uses an even more sophisticated technique to reduce noise further. It consists of a sound-absorbing concrete base containing flask-shaped slots (瓶型狭槽) up to 10 millimetres wide and 30 millimetres deep that are open at the top and sealed at the lower end. When sound waves of specific frequencies enter the top of a flask, they set up resonances (共鸣) inside and the energy of the sound dissipates (消散) into the concrete as heat.
Kuijpers believes he can cut noise by five decibels compared to the quietest of today’s roads. The success of Kuijpers’ design will depend on how much it eventually costs. But for those affected by traffic noise there is hope of quieter times ahead.

【推荐1】From ordering food to buying a new book to making a charitable donation, more and more decisions that used to be made on paper are now being made on digital devices like tablets, phones, and computers. And this trend towards digitalization has many advantages, in particular when it comes to efficiency and sustainability — but could it also be negatively influencing how we make decisions?
We conducted a series of studies with more than 2, 500 participants across the U. S. and China to explore the impact of the medium you use to make a decision, with a particular focus on decisions with some sort of moral component, such as whether or not to make a donation to a charity, or whether to choose a healthy or unhealthy entrée (主菜) at a restaurant. We asked the participants to make a variety of these sorts of choices using either a paper form or a digital tablet, and despite controlling for all other variables (变量) , we consistently found that people who used paper made more moral decisions than those who used a digital device: For example, participants who read their choices and made a selection on paper were significantly more likely to give money to charity, choose a healthy entree, and opt for an educational book rather than something more entertaining.
Why might this be? Our research suggests that the key mechanism driving this effect is how “real” the decision feels. We asked participants in two of our studies to describe how real a decision felt, as well as the extent to which they believed the decision as representing who they were as people, and they consistently indicated that making a choice on paper felt more real and representative than making the same decision on a digital device.
It may seem like a minor detail, but our research shows that the medium with which your customers, employees, or community members make a decision can have a major impact on the choices they make. This has implications (暗示) for marketers, policymakers, and anyone seeking to encourage any sort of virtuous behaviour. For example, to encourage customers to choose healthier options, restaurants might consider opting for paper rather than digital menus. Similarly, parents and educators might opt to provide students with paper rather than online book order forms, to increase the chances that they’ll choose educational reading materials.

【推荐2】More and more travellers in China nowadays prefer homestays rather than traditional hotels, as they seek private living experiences. The house-sharing model was first introduced by the website Couchsurfing.com in 2003. It is still the largest website for travellers to find accommodation (食宿) without much money to spend.
Encouraged by her great experience of homestays in France, Maggita, 30 considered short-term hire as her first choice in her future trips. She later went back to her hometown Shanghai and ran a “shared accommodation” business.
For travellers, the short-term hire idea enables them to rent a special room at a reasonable price and also enjoy a first and experience of the local culture, compared with traditional hotels. For owners, they can gain much with daily rental. Now Maggita has quit her last job in an IT company and become a host of some 20 homestays, which enables her to earn a monthly income of around 40,000-50,000 yuan.
In recent years, China has see n many homestay booking websites such as Xiaozhu and Tujia. Chen Chi, the founder and CEO of Xiaozhu, said the model is to share rooms or apartments that are not in use with people who need them. Instead of the traditional view that Chinese people feel uncomfortable living with strangers. Chen found that a large number of travellers got along well with house owners.
However, experts have pointed out a series of problems brought about by the fashion. Lacking supervision (监管) to those accommodation sharing websites, the service quality and accommodation safety cannot be guaranteed. Experts suggest that the online websites should closely work together with communities and local police stations to improve the services.

【推荐3】Technology has changed almost everything. With the Internet and mobile phones, everyone is now connected. Mobile phones are no longer just a luxury (奢侈品). They have played an important part in people's lives. And today, there is a very long-standing debate about the use of mobile phones in the classroom.
First of all, mobile phones can keep students connected. With mobile phones, parents might be less worried since they can easily check on their children, and students can easily call their parents. Secondly, they encourage shared learning. Students can share notes and reminders faster and easier with mobile phones. Moreover, mobile phones can be used as memory support. Students can record their lessons by taking pictures and / or videos for future use. With smart phones, learning can also be more fun. Additionally, students can use their phones for taking down notes and creating reminders. Last but not least, smart phones are an excellent source of information. Students can search for information on the Internet, or use the dictionary and translation tools on their phones.
However, allowing students to use their mobile phones in the classroom has some big disadvantages. For example, students' attention can easily be drawn away when their phones ring, and the learning process comes to a complete stop when students start to send and read messages or make and receive calls. Moreover, with the appearance of smart phones, it is now easy for students to play on the Internet or shop online. Smart phones can also be used for cheating (作弊). Text messaging is the new note passing. Students can exchange test answers through text messages without the teacher knowing. Finally, mobile phones can cause health problems. Playing with phones for long periods of time can harm students' eyesight, and the radiation (辐射) emitted from mobile phones may be bad for students' health.

【推荐1】When parents ask, “What grade did you get?” there is a common follow-up question: “So who got the highest grade?” The practice of making such social comparisons(比较) is popular in all corners of the world. Many teachers choose and publicly announce the “best student” in a class. Adults praise children for doing better than others. People cheer for the athletes who defeat others.
Social comparisons are well meaning: we want to make children feel proud and push them to achieve more. Yet social comparisons can backfire: children can learn to always compare themselves with others and become caught up in a harmful cycle(循环) of competition.
One well-known method to remove social comparisons is to provide participation prizes for children who take an active part in activities. Such prizes, however, may not end social comparisons: A high achiever who receives the same prize as a low achiever may feel unfairly treated. More generally, those who are highly praised unexpectedly may come to believe that they do better than others and thus have reason to be given a prize.
How, then, can we make children feel proud of themselves and encourage them without the unwanted side effects? We believe a better way is to use temporal comparisons—encouraging children to compare themselves with their past self rather than with others, such as by checking on their progress. Adults should teach children that doing better than oneself is more important than doing better than others and that even small achievements can be celebrated.
1. Why do parents compare their children with others?A.To make the practice more popular. | B.To give children the desire to do better. |

【推荐2】From now on, never spend your precious time thinking of reasons for your failures and shortcomings. Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.
The seeds, and the power to grow them, are contained in the most awesome machine ever created: the human mind. Success is a choice and not a chance. You were born a winner: You can be a success if only you make the right choice.
You cannot be successful without first developing your self-esteem. Your level of self-esteem is always based on the degree of control that you are able to exercise over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power, or responsibility for their lives. They are leaves tossed (摇摆) by the winds of chance blown about with any sudden change in the weather.
You can exercise control over your life only to the degree that you believe that you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.
Everything happens as a result of something. If we can identify the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for letting out expectations. Our success is dependent upon our level of confidence.
In short, in all areas of your life, whether they be financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it, you are on the road to success.
1. People with low self-esteem are compared to leaves because they_______.A.can’t exercise control over themselves | B.are ready to change their minds |

【推荐3】Parents can begin good organization (条理) habits with preschool-age kids, Experts recommend asking them to do small, simple actions on a regular basis with the help of parents. Maybe they open their bags and bring their lunch bag to the kitchen, or take their shoes off at the door and put them in a nearby closet. These won’t save parents much time but they will help develop good habits.
When kids enter primary school, they should be ready for more responsibility. This is the time to teach them about daily routines, and help them take control over theirs. Parents and children might sit down together and make a list of everything that needs to be done to get out of the house in the morning, or get ready for bed at night. Together, parents should figure out how long each activity takes, and when the best time to do them is. Some of the kids might want to get their bags ready and pick out their clothes the night before.
It’s also wise to create a firm schedule for homework. When do kids do their homework? How long do they need? Where do they do it? Where will the homework go once it is done? Figure them out and stick to the schedule as much as possible.
Parents should print up these task lists and help kids finish them step by step. Kids might even check them off each morning or evening. Also, make sure there are clocks in the rooms in which these tasks will take place. Time management is an important part of learning organization, but it can’t be done if kids don’t know what time it is.
Organization gives kids the chance to make it possible to focus on a task and complete it. Kids tend to be more motivated to learn organization skills if they see organization as a challenge to overcome, rather than a fault to repair.
