I'm part of the Roots & Shoots program founded by Dr. Jane Goodall. The program is intended to make and promote positive changes in the world. As Dr. Goodall says, "What you do makes a difference, and you have to decide what kind of difference you want to make."

    In Bulgaria, where I live, homeless dogs are everywhere. Many people here turn a blind eye to them. But I cannot ignore the life of a street dog whenever I see one wandering in the street, looking for something to eat. That's why I'm no longer a food waster. When I see wasted food, I always think of a hungry dog climbing to garbage bins, searching for food that people have thrown there. When eating in a restaurant, I'm not afraid to take leftover food to feed stray cats or dogs.

    A week ago, I saw a homeless dog around the garbage bins. Immediately I knelt down, spoke to her softly and ran my hands over her. I could see that she had had puppies. I couldn't imagine how she could have been able to care for them. Hours earlier, I'd bagged up a plate of leftover fish. As I unwrapped it, she wagged her tail and sniffed at it. She ate all the fish in no time.

    It's sad, isn't it? I can't understand why many of us waste so much and think little of it. These homeless animals have taught me that food is precious. Even when I don't have leftovers with me, I'll take the time to get something from the grocery store to feed them.

I know my power is small, so I hope that next time you see wasted food, do turn it into worthy food. You have the power to save a life!

    Mass media are tools of communication.Mass media allow us to record and pass information rapidly to a large，scattered(分散的)audience.They extend our ability to talk to each other by helping us overcome barriers caused by time and space.

    There are various ways in which mass media make daily life easier for us.

    First,they inform and help us keep a watch on our world. They gather and pass on information we would be unlikely or unable to get on our own.

    Second，mass media help us to arrange our time and life.  What we talk about and what we think about are greatly influenced by the media.When people get together，they tend to talk about certain happenings in the newspapers or on TV.Because we are exposed(暴露)to different points of view through different kinds of media every day，we are able to evaluate(评价)all sides of a certain issue.

    Third,the media are used to persuade people. A good example is advertising through the media.Newspapers，magazines and TV are filled with all kinds of colorful，persuasive advertisements.Though many advertising may not say openly that they want you to buy a certain product，they describe their products in such a way that you may want to buy them.

    Fourth,the media also entertain.  All of the media make some efforts to entertain their audience.For instance，even though the newspaper is primarily a medium of information，it also contains entertainment features(特征)．Television，motion pictures，fiction books and some radio stations and magazines are devoted mainly to entertainment.It is estimated that in the future，the entertainment function of mass media will become even more important than it is now.

    Animal Farm by George Orwell

    Animal Farm is probably one of the most popular school reads in the world. George Orwell wrote it as a political allegory(讽喻)and has since then inspired the minds of not only adult revolutionaries but also the younger ones who start feeling the spark of being right and free for all of the humanity in their hearts.

Persepolis by Marjane Satrapi

    This is a wise, funny, and heartbreaking memory of Marjane Satrapi's years growing up in Iran during the Islamic Revolution, and how she dealt with life while experiencing the ruinous effects of the war with Iraq. The mistakes she felt she made opened her eyes and shaped her into becoming the influential individual she is today.

    To Kill a Mockingbird by Harper Lee

Regarded as a masterpiece of literature—-it is no wonder it won the Pulitzer Prize. The plot and characters are based on the author's observations of her family and neighbors, as well as on an event that occurred near her hometown in 1936, when she was 16 years old. The novel is famous for its warmth and humor, despite telling a story of innocent Tom Robinson being accused of raping(强暴)a white woman because he was black.

    The Harry Potter series by J.K. Rowling

    A story showing the absolute courage of a young boy, who was never afraid to speak his mind in the face of injustice and would always defend the helpless. A boy shows us the importance of believing in ourselves and others. Harry Potter reminds us that the true power to defeat any enemy is not found in others, but found within each of us.

    It is quite natural for all of us to want to preserve and protect the foods we purchase. With that in mind, we always think that the best way to do that is by putting them in our refrigerators. However, the following foods should never be placed in the fridge.

    Bananas

    Bananas should never be placed inside the refrigerator because they keep nutrients better outside the fridge. Bananas are better kept on the counter until they ripen. The cold temperatures actually slow down the ripening process of the bananas, while the wetness and darkness of the fridge will only lead to rotting.

    Potatoes

    Potatoes should be placed in a cool, dry and dark space. The cold temperature of the fridge can turn starch (淀粉) into sugar more rapidly. It is also recommended that potatoes be removed from plastic or paper bags they may have been placed in. Also, keep them unwashed, as well in an uncovered cardboard box.

    Garlic(大蒜)

    Placing garlic in your refrigerator will actually cause it to shoot. The garlic will also rotten and even rubbery. Moreover, inside your fridge, the look of the garlic will rarely change. This means you won't be able to tell if it's any good until you finally slice it open.

    Onions(洋葱)

    Placing your onions inside your refrigerator will eventually end up turning them rotten and soft. Unpeeled onions should be kept out of plastic bags and fridge. One of the reasons for this is because unpeeled onions require and need air exposure for maximum life. If you have peeled (剥皮) an onion though, then you should keep it in the fridge, in a covered container.

    Sports can help us a lot. Taking exercises can make us strong. In collective（集体的）sports like basketball, volleyball or football, we will learn the importance of cooperation(合作). And sports can also help us relax after work or study.

    However, as the saying goes, “there are two sides of everything.” Sometimes we may hurt other players or ourselves if we are not careful enough when participating(参加) in sports activities. What's more, too much or hard practice can be bad for our health.

    Sports can make us healthy both physically and psychologically(心理地). It is also a good way for people to know each other and can improve friendship between people. So long as we are careful enough, sports can do us nothing but good.

    There are many weird sports that are present from around the world. From each region of the world, along with the very popular common sports, there are also those really popular but very weird kinds of sports.

    The Ultimate Test between Man and Horse:

    This indeed a very strange kind of sport that tests your stamina. You will learn how to be agiler while competing against a horse. This game originated in Welsh town of Llanwrtyd Wells. This sport really has to do with strength. You will require great agility and strength in order to take part in this. Marathon human contestants are put to test against those mounted on horses. This is how the marathon testing takes place.

    Love Locked Race

    This is a sports event that was first introduced in Finland. This is all about a male competitor racing with a female in a certain way. There would be many obstructions and blocks on the way which would definitely bring you challenges. The person to win would have to finish the race without losing his female partner in the course of overcoming the obstacles even for once. This race takes place really fast and the obstacles are set that way.

    Toe sport

    This is yet another weird sport that welcomes you to use your toes. This is quite the same kind of sport that you used to play as a child which involved toe wrestling. This has now been turned into a major sport that even has a World Toe Wrestling Competition. It first originated in a pub of Derbyshire.

    The locals took this sport with great enjoyment and then made this so popular that it soon had its own championship. The individuals who participate have only got to use their feet in locks but then this is tougher than it may sound.

    The Mud Pit Belly Flop

    This is a kind of game where even the spectators get splashed in mud but in fact that is quite the fun. The very annual Summer Redneck Games in East Dublin brings about this game and brings about some of the greatest hubcap discus throws with it. This is also a great sport to show the strength and dexterity of your feet.
