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.

    When I was six, Dad brought home a dog one day, who was called “Brownie". My brothers and I all loved Brownie and did different things with her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games, Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them, we always felt better when she was around.

    One day, as I was getting her food, she chewed up(咬破)one of Dad's shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked at her and said, "Bad girl," she looked down at the ground and then went and hid. I saw a tear in her eyes.

    Brownie turned out to be more than just our family pet, she went everywhere with us. People would stop and ask if they could pet her. Of course she'd let anyone pet her. She was just the most lovable dog. There were many times when we'd be out walking and a small child would come over and pull her hair. she never barked(吠) or tried to get away. Funny thing is she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loves everyone.

(Now many years have passed since Brownie died of old age. I still miss days when she was with us.)

    Life is difficult.

    What do you think about life? Maybe most people say that life is difficult. But life is no longer difficult once we truly understand and accept it. Most people do not fully see this truth. Instead, they complain about their problems and difficulties as if life should be easy. It seems to them that their difficulties represent a special kind of suffering especially forced upon (强加于) them or their families, their class, or even their nation.

    What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.

    Yet, it is in this whole process of solving problems that life has its meaning.

    Problems are the serious test that tells success from failure. When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, "Those things that hurt instruct." It is for this reason that wise people learn not to fear but to welcome the pain of problems.

    On my first day of high school, I asked an eleventh grader where my class was. And he told me it was "on the fourth floor, next to the pool." I found out five minutes later that we don't even have a fourth floor and there's no pool either! Besides that, I didn't have any trouble with the older kid.

    I think the biggest difference between middle and high school is the homework load (工作量) and size of the school. I went from maybe fifteen minutes of homework a night to several hours, so I had to learn how to make full use of time! Our class size is around 550, but joining in clubs, sports, music, and other activities at school makes it easier to get to know people in every grade.

    The best advice I can give about the years you spend in high school is to learn things for yourself, not just to get a good grade. There have been so many tests that I've prepared for the night before, gotten an A, and not remembered anything later. I've changed that this year, and I enjoy school so much more. Don't take easy classes just to have a simple year. If you have a choice between chemistry and sports, the first will prove to be a lot more useful!

    While drinking and smoking might be present in some middle schools, they're also around in high school. I have a lot of friends who promised they'd never drink or smoke, but are now partying every weekend. If you have "fun" and spend your nights wasted instead of studying, you will regret it when you're applying for (申请) college. The "friends" who say you're a loser for not partying are really not your friends at all. It's hard to see your closest friends grow apart and go in different directions, but don't follow their footsteps. Create your own path in life and make your own decisions.

    Sparrow is a fast－food chain with 200 restaurants. Some years ago，the group to which Sparrow belonged was taken over by another company. Although Sparrow showed no sign of declining，the chain was generally in an unhealthy state. With more and more fast－food concepts reaching the market，the Sparrow menu had to struggle for attention. And to make matters worse，its new owner had no plans to give it the funds it required.

    Sparrow failed to grow for another two years until a new CEO，Carl Pearson，decided to build up its market share. He did a survey，which showed that consumers who already used Sparrow restaurants were extremely positive about the chain，while customers of other fast－food chains were unwilling to turn away from them. Sparrow had to develop a new promotional campaign.

    Pearson faced a battle over the future of the Sparrow brand. The chain's owner now favored rebranding Sparrow as Marcy's restaurants. Pearson resisted，arguing for an advertising campaign designed to convince customers that visits to Sparrow restaurants were fun. Such an attempt to establish a positive relationship between a company and the general public was unusual for that time. Pearson strongly believed that numbers were the key to success，rather than customers' spending power. Finally, the owner accepted his idea.

    The campaign itself changed the traditional advertising style of the fast－food industry. The TV ads of Sparrow focused on entertainment and featured original songs performed by a variety of stars. Instead of showing the superiority of a specific product，the intention was to put Sparrow in the hearts of potential customers.

    Pearson also made other decisions which he believed would contribute to the new Sparrow image. For example，he offered to lower the rent of any restaurants which achieved a certain increase in their turnover(营业额).

    These efforts paid off，and Sparrow soon became one of the most successful fast－food chains in the regions where it operated.
