    Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.

    So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don't we use them for collecting energy?

    The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?

    The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.

    Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.

    We just can't wait to see more of these roads all over the world in the near future.

    Many kids help out around the house with chores(家庭杂务) such as emptying the dishwasher, putting laundry away, and taking out the trash. In exchange, some kids get allowances(补贴) 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 ChoreMonster 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 ChoreMonster. "Kids need positive reinforcement(强化) 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?

    Are you preparing for a big test? If so, you may want to go to play some basketball in between hitting the books. Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels (血管), including those in the brain, stronger and more fully developed. Dr. Cameron is sure that this allows people who exercise to think better. As she says, “While we already know that exercise is good for the heart, exercise can actually cause physical changes in the brain.”

The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement show greater brain development than babies who are less physically active. Even a little movement can show big results. Margaret Barnes, a scientist, also believes in the importance of exercise. She thinks that many learning disabilities that children have in primary school or high school can result from a lack of movement as babies. Babies need movement that encourages and excites their five senses. They need to set up a connection between motion and memory. In this way, as they get older, children will begin to connect physical activity with higher learning,” says Margaret.

    Older people can develop their brains as well. Cornell University studied a group of seniors who have a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exercise for older people should not be too simple. Learning some new skills or actions, such as with yoga or tat- chi helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main aim is to increase the brain's flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.

    Wild mangoes come from the foothills of the Himalayas. They are by far the most important fruit in India, and have been cultivated there for four thousand years. The arrival of the mango tree in other parts of the world was probably due to the Portuguese who carried mangoes via Goa to Africa, from where they eventually reached the New World. Mango trees are now so well established in many tropical countries that it might appear that they have always been there.

    Like many tropical trees, the mango tree is multi-purpose product. Its wood is used in boat building, and its leaves can be fed to cattle. Most of the mango crop is consumed in the areas where it is grown, but in recent years mangoes have gained in popularity across the world as people in mild climate become increasingly eager to enjoy the delight of the fresh fruit.

    The global market for mangoes is very profitable, and mango producers are keen to make use of the fruit's growing popularity. Modern shoppers not only appreciate the fruit's high nutritional value(the mango is a good source of vitamin A and C, protein and fibre), but also expect it to look and taste perfect. Therefore producers now select only the best quality seedlings which have the most chance of developing into good quality fruit.

    Mangoes are high in fiber, thus making them very good for the heart. The high fiber content is also helps easing constipation. They have high pectin(果胶) and vitamin C content that reduces the blood cholesterol levels and serves as an immune booster. This fruit is rich in anti-oxidants, vitamins, minerals and contain an enzyme(酶) that has stomach soothing properties. These enzymes act as a digestive aid and digestive proteins.

    Although the mango tree has spread from its native Himalayan foothills to the tropics, delivering the fresh fruit to the world's supermarkets presents a challenge, as it does not travel well. Producers transport the fruit by speedy but costly air freight (货运)for minimum delay rather than risk the cheaper but slower road or shipping routes which, can result in damage to the fruit.

    Mangoes are usually in storage for some time after their arrival at their destination. The fruit must be kept cold, or the sweet, juicy flesh will soon become over ripe and the mangoes will be unfit for sale. Fortunately, extremely effective refrigeration is now available and this is the best way of preventing the fruit from going bad before it reaches the supermarket shelves.
