1 . Vehicles on our roads are now mostly petrol and diesel (柴油) cars, but their days cannot continue for much longer. A recent university study found that current electric cars could be used for 87 percent of daily car journeys in the US. That figure could rise to 98 percent by 2020.
One hurdle to the widespread adoption of electric cars has been “range anxiety” — drivers concerns about running out of electricity on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.
Attitudes towards electric vehicles have changed greatly over the last few years. Not that long ago, electric cars were met with distrust, and their high prices drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade picky consumers. Plug-in cars will soon give internal combustion engine (内燃机) models a run for their money.
As well as development on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make commercial electric flight a reality.
Electric vehicles do not produce any emissions (排放). If the US could replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 percent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim (声称) to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

2 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

5 . Many kids help out around the house with chores such as emptying the dishwasher, putting laundry away, and taking out the trash. In exchange, some kids get allowances or other rewards such as extra computer time.
But some people do not think that kids should get rewards for doing chores. Susie Walton, a parenting educator and family coach, believes that by rewarding kids, parents are sending a message that work isn’t worth doing unless you get something in return. “Running any kind of household is a team effort,” Susie said. “A home is a living space for everyone in the family. It’s important for kids to see that we all have responsibilities in the house, and that families decide together how they want their home to look, and how they are going to keep it looking like everyone wants it to look.”
Other people believe that getting a cash allowance or other rewards motivates kids to do chores, and it also teaches them real world lessons about how we need to work to earn money. There are also new applications that give kids points and digital gifts that can be redeemed (兑取) either online or in the real world. With the Chore Monster app, kids earn digital points by completing chores that they can turn in for real-life rewards such as extra Xbox time or a trip to the mall. “Our goal is to encourage kids to earn rewards.” says Chris Bergman, founder of Chore Monster. “Kids need positive reinforcement to help motivate them.”
What do you think? Should kids be rewarded for doing chores? Or should kids help out around their homes without getting anything in return?

8 . Losing your ability to think and remember is pretty frightening. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn’t worry. There are pretty clear differences between signs of dementia and age-related memory loss.
After age 50, it’s quite common to have trouble remembering the names of people, places and things quickly, says Dr. Kirk Daffner of Brigham and Women’s Hospital in Boston.
The brain ages just like the rest of the body. Certain parts become smaller, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.
Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says.
When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved”. Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrong.
But even then, Daffner says, people shouldn’t panic. There are many things that can cause confusion and memory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.
You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive (认知的) reserve, Daffner says.
“Read books, go to movies, take on new hobbies or activities that force one to think in novel ways.” he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a widely known to boost the brain.

9 . Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son. Suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut,” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up (依偎) against me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is understanding which time is which.”
Before age 11, children like to tell their parents what’s on their mind. “In fact, parents are first on the list,” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years,” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (思想的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

| A．Parents shouldn’t be angry with teenagers. |
| B．Parents have to talk with children face to face. |
| C．Parents are unhappy with their growing children. |
| D．Parents should try to understand their teenagers. |
10 . There are people for whom the motivation lies in their family’s or companions’ duties. For some people, the purpose lies in a soul’s spiritual awakening. Brent Clayton, a firefighter by profession, is such an individual who found his purpose early in life and kept working to fulfill it.
Born on March 3, 1984, Clayton hugely felt the need to serve others. He followed his mission in life and acquired his diploma in Public Safety. He gradually realized the importance of securing people’s lives, which strengthened his faith in his mission. Clayton further pursued his bachelor’s degree from the University of Melbourne and master’s degree from Federation University. Then, Clayton worked in the military for a period before moving into a role with the prison service as a prison guard, the youngest person to ever be employed by the service at the time.
After spending a decade in the fire service including training and recruitment, he gained enough experience to become Australian most prominent fire service recruitment expert. Clayton devoted many years of his life to the firefighter recruitment process and fire service industry. He wanted people to realize the true value of this profession by establishing its significance. To communicate his perspective, Clayton established Fire Recruitment Australia in 2009. He aimed to train the next generation and prepare them for the future. Clayton used his experience and years-long training to prepare candidates who were as enthusiastic about the well-being of the world as him.
Keeping the point in mind, Clayton wrote the book Fire Service Recruitment-The Process to Success. His idea was to join his learning into an accessible medium so others didn’t have to waste years wondering what to do when applying to become a firefighter. After the success of the book, Clayton introduced candidates to a comprehensive test preparation and learning suite to facilitate success throughout each stage of the selection process. This platform helped him as well as his candidates to work together for the betterment of themselves and society at large.
