Hello. I'm Jan from Mrs. Lake's class. My class wants to work together to help the public. We think we have found a great way to do this. Last month we did a class project on the highways near our town. We learned about the Adopt-a-Highway Program. This program brings people together to pick up litter along the roads. We think it would be a great idea for all students in our school to join the program and adopt（收养） a highway.

    Adopting a highway is not like adopting a pet. When a highway is adopted, only part of the highway is cared for by a group of people. The group agrees to work every week to keep its part of the highway clean. Each group gets its own sign that has the name of the group printed on it. The sign is put up at the side of the road. This sign lets drivers know who is keeping that area of the road clean.

    The Adopt-a-Highway Program is a great way for people to help their environment look nicer. Also, the government does not have to send out as many road workers. This saves money. Finally, people may try harder to keep roads clean if they see people, especially teenagers like us, cleaning them up.

    We will need helpers to care for our adopted highway. If you want to feel great and keep our roads clean，please come with your parents to the meeting next week. We will meet in Mrs. Lake's room on Wednesday at 6:00 P.M. At the meeting, we will talk about which roads are the dirtiest as a result of people's unkind acts. Then we'll try to pick an area to adopt and clean.

    I look forward to seeing you at the meeting. Remember to keep our roads clean!

    Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.

    Have you ever wanted to travel back in time? What about traveling into the future? There's an easy way to do it.

    One way you can make a time travel journey is by writing a letter to your future self to be opened in the future. To your future self, the letter will be a visit from the past. What can be gained by writing a letter to yourself? It depends on how good your letter is. You have the chance to say something to your future self. What would you want to communicate? You'll be able to talk to yourself 5, 10, 15 years down the road. There may be instructions for your future self, or you may have goals that you will want to check up on.

    There are a lot of things you could include in your letter or letters to yourself. The more you include, the better the letter will be to you. Here are some ideas of things to include in your letter:

    Your thoughts and feelings about life, religion, politics, society, etc.

Your feelings for your family.

Your likes and dislikes.

Your dreams.

    The type of person you want yourself to become.…

    Be creative with what you put in your letter. Include a picture of yourself or family to show the period from which the letter came.

    You can store your letter in many different ways. You can give your letter to a friend or family member to keep and mail to you. If you can get others to take part, have them write letters to themselves as well and ask someone to be the letter holder until it's time to send the letters. You can also use a service online to store your letter and e-mail it to you.

    Make the most of your letter writing, and you will help your future self make the most of the present.

    In 1972, a social worker named Sanjit "Bunker " Roy founded Barefoot College in Tilonia, Rajasthan. Today the college trains women from villages for six months to build and maintain solar panels and other instruments. Barefoot College also offers education to the younger generation both during the day and at its solar bridge schools that meet by lamp light at night.

    The philosophy of the Barefoot College is largely inspired by the principles of Gandhi, starting with quality beyond social classes, sex or religion. As a matter of fact, women are favorably regarded as an underserved population that is necessary to bringing villages together. Another central principle of the college is self-reliance, teaching students to support and think for themselves.

    After the colleges female students have completed their half a year of training, they return to their villages villages, where they wait for solar panel parts to arrive from the college. Once they have all the pieces they need ,they construct the panels and begin collecting solar energy. For each village, the college also provides solar lamps. Villagers can, in addition, order parts for other solar-powered devices, such as water heaters and cooking stoves. Once assembled(组装）, they and the lamps are powered by the solar panels.

    The effect on the villages is huge. Before the solar panels and lamps arrived, villagers had only candles to light their homes. This prevented adults from doing serious work at night, and it made studying difficult for children as well. As for physicians, they have difficulty treating patients and performing operations at night because they had to rely on flashlights.

    Now there is power for not only the electrical appliances that the college provides but also devices like televisions, radios and computers. For the first time, the villagers can even connect to the world through the Internet.

    Getting on the school bus, like the possible dangers around the home, getting on the school bus can also bring its own set of dangers. There are several important safety measures that parents should be aware of when it comes to bus safety.

    Parents should always make sure that someone is taking charge of children at the bus stop to make certain clear ground rules which are in place and are being followed—particularly rules that forbid horseplay in and around the street.

    Teach children to ask the bus driver for help in picking up anything they may have dropped around the bus, as children getting dropped articles are often hit by the bus or another vehicle because they are not seen by the bus driver or by oncoming traffic.

    Children should be asked to take five large steps away from the bus when they get it off, and make sure that the bus driver can see you and look you directly in the eyes to signal it is OK to cross the street. It is still very important that children also look both ways as they cross the street.

    Inform children that they must never speak to any stranger who talks with them first and that they must never accept a ride from any person unless their parents tell them directly that it is OK. Teach kids that adults should ask other adults for help, not kids. If an adult asks a kid for help, that child should get another adult.

    If for any reason a child feels uncomfortable or unsafe at the bus stop they need to bring it to a parent's or caregiver's attention.

Remember, planning ahead is always the best safety measure. Follow these rules and your family will be off danger!

    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.)
