Oct. 16 is World Food Day. The UN started the day in 1979. It's used to remind people not to waste food and fight hunger.

    A big number of people in the world still don't have enough food to eat. Food shortage(匮乏) is a big problem worldwide. Right now, there are more than 1000 million hungry people in the world according to the UN. Many children go to sleep hungry, and 15 million of them die of hunger each year.

    There are several reasons why there are food shortages. First,there have been more droughts(干旱) and floods recently. Also,a growing population makes feeding everyone more difficult.

    Another big reason is food waste. Most people don't realize how much food they throw away every day. Sometimes we cook too much, or we don't use it goes bad. The average(平均的) person throws away 50kg of food every year. According to the UN, more than third of all food produced worldwide goes to waste each year.

    That is over 1,300,000 million kilograms of food being wasted. The amount of food wasted in Europe can feed 200 million people, and the food wasted in Latin America can feed 300 million a year.

    So think twice next time you want to throw away food.By cutting down on food waste, we could help put food on the empty plates of some hungry children. Only order as much food as you can eat at a restaurant. If you can't eat all you order, take the rest home. Don't be too picky about food so that you don't leave any on your plate. Some food may not taste great, but your body needs it. Keep an eye on what food you have at home. Don't buy too much. Don't cook too much.

    When you throw away food, you are not just wasting the food itself. Resources(资源) are also wasted while growing, transporting and cooking the food. These things all take energy, time and water.

    Playing is serious business for children．In fact, it's what they do best! Ask them why they do it, and kids will probably say, "Because it's fun!" But it's much more than that．It's also good for them．

    Studies show that from birth babies begin learning through playing．They use their five senses to get to know their new world．Touching allows them to discover how different things feel．Brightly coloured toys and clothing help develop a baby's sense of sight (视觉)．When small children choose which toy to play with, they begin developing their abilities in making decisions．

    Children love toys that allow them to use their imagination (想象力)．Sometimes an empty box is more fun than a high-tech (高科技) toy．That's because a box can become anything to a child．

    Crayons, paints and Play-Doh (彩色塑泥) are also good because they allow children to create．Traditional building blocks teach important pre-maths skills．

Playing doesn't become any less important once children start school．Many valuable lessons about life are learned on the school playground．Kids learn how to share, take turns and play by the rules．
