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.

    If you need to call your parents but your smartphone(智能手机) is not with you, can you remember their numbers? To remember 11 numbers is not difficult. _______, many of us can't because of the smartphone. What's more, people are not good at giving directions and face-to-face talks because of smartphones. Even when friends are having a meal together, it's common to play with their phones. Smartphones weaken（削弱） our skills in many ways.

    According to a study, Chinese people spend about 170 minutes on their smart phones every day. For students, spending much time on smartphones isn't good for their study. The study shows children who spend more than four hours a day on their phones get much worse grades in school tests than those who play with their phones for 30 minutes.

    It's true that the smartphone makes our lives easier. But many people also think spending too much time on it is bad for their study or work. People are trying to change that.

    People make a new game called Forest. It lets users plant a seed that grows into a tree over the next 30 minutes. During it, users can't use their phones, or the tree will die.

    There is a restaurant in the USA. It gives people a discount(折扣) if they don't play with their smartphones during a meal. Owner Mark Gold said that he hoped it gave people a way to enjoy their meal and talk with friends and family.

    The table above shows the sleeping patterns (模式) of people doing {#blank#}1{#/blank#} jobs. It is clear that there are big differences among them. For example, students continuously (连续地) sleep for {#blank#}2{#/blank#}each night because they go to school during the day. {#blank#}3{#/blank#} are busy and stressed out, so they only sleep for 6 hours. But they also sleep continuously during the night. Truck drivers sleep 6 hours and doctors sleep the {#blank#}4{#/blank#} hours among the five. However, because of their jobs, they have to divide their bedtime into different periods. Finally, {#blank#}5{#/blank#} mothers sleep when their babies do. They often have to wake up during the night to comfort (安抚) their babies. It is important to consider sleeping patterns when choosing a job.

    Liu Wei is very famous in China because he can play the piano with his toes(脚趾). One day when Liu Wei was only 10 years old, he played a game with some friends. He lost both his arms because of electricity(电). Liu Wei was very sad when both his arms were cut off after the accident. But soon he had to make a choice. "For people like me, there were only two choices. One was to give up all the dreams, which would cause a quick death. The other was to work hard without arms to live an excellent life." says Liu Wei. Liu's dream was to be a pianist. His excellent life included a show on China's Got Talent(《中国达人秀》) and a wonderful performance(演奏) playing the beautiful Marriage D'amour with his two feet on the piano. Liu Wei learned to play the piano with his feet. And teaching himself to play the piano with his feet was very hard. Many times he wanted to give it up, but his parents went on encouraging(鼓励) him and he wanted to make his parents proud. Maybe you can not believe that Liu Wei is able to play well only with his toes. The audience(观众) were deeply moved and very excited when they watched his performance.

We are often warned by our teacher not to waste precious (宝贵的)time, because time lost will never return. I think it quite true. What does time look like?  {#blank#}1{#/blank#}. Time is abstract (抽象的), so we have to think about it.

Time passes very quickly. {#blank#}2{#/blank#}.  It is because they don't know how to make use of their time. They waste it in going to theatres, cinemas and parks, and doing other things. Why do we study every day? Why do we work? Why do most people would rather take buses instead of walking? The answer is very simple. {#blank#}3{#/blank#}.

Today we are living in the 21st century. {#blank#}4{#/blank#}. When a person dies, his life ends. Since life is short, we must devote our time and energy to our study so that we may be able to serve the people well in the future. {#blank#}5{#/blank#}, for it does not only bring us failure but also does us other harm. If it is necessary for us to do our work today, let us do it today and not leave it until tomorrow.
