Food waste is a world's problem. Every year, about 1.3 billion tons, or one-third of all the food produced is thrown away, according to a survey. {#blank#}1{#/blank#}(use)just 25 percent of that wasted food could feed 870 million hungry people, which would end world hunger. The people of France wasted 234 pounds of food per person, which is much better than some other{#blank#}2{#/blank#}   (country).

    In the past, France wasn't{#blank#}3{#/blank#}at controlling food waste, but now the country takes the lead. A law was{#blank#}4{#/blank#} (make) by French government. It made France the first country in the world to prevent supermarkets from{#blank#}5{#/blank#}(throw) away unused food. Now supermarkets of a certain size must donate unused food, or they will face a fine. {#blank#}6{#/blank#}  are other rules requiring schools to teach students about food sustainability (可持续性).They also ask companies to report the food waste numbers in their environmental reports. And restaurants should provide take-out bags.

    These laws make it a standard to reduce waste." says Marie Mourad, a student in Paris who has {#blank#}7{#/blank#} (write) several reports on French food waste." France is not the country that wastes the least food, {#blank#}8{#/blank#} Frenchmen have become the most active because they want to be the example in Europe.'* This step has influenced parts of French food industry. It is everyone's duty to fight {#blank#}9{#/blank#} food waste. Everyone on the earth should {#blank#}10{#/blank#} attention and take action.

    People spend almost a third of their lives doing one thing—sleeping. Every year, there is a day for people around the world to celebrate the {#blank#}1{#/blank#} (important) of good and healthy sleep—World Sleep Day.

    Sleep is like food for the brain. Healthy sleep helps the body and brain grow and develop. People of different ages need different amounts of sleep. It is said that eight hours per night {#blank#}2{#/blank#} (consider) the average amount of sleep. For students aged 10 to 17, a healthy amount is about eight to nine hours per night. However, last year, the China Youth and Children Research Center {#blank#}3{#/blank#} (report) that about four {#blank#}4{#/blank#} (five) of middle school students didn't get enough sleep. For some students, they want to sleep early, but they keep {#blank#}5{#/blank#} (worry) about their schoolwork and can't fall {#blank#}6{#/blank#} (sleep) quickly. A lack (缺乏) of sleep can greatly affect (影响) a person's life. Students who don't get enough sleep may get poor grades. They cannot pay attention in class or do well in sports.

    {#blank#}7{#/blank#} (solve) this kind of problem, scientists advise that students should have {#blank#}8{#/blank#} (little) schoolwork and more time to sleep. There are some other ways to help people get enough sleep, such as {#blank#}9{#/blank#} (take) a 20-minute nap (午睡) during the day, trying to go to sleep earlier and so on . Good sleeping habits are also {#blank#}10{#/blank#} (help). For example, try to go to sleep and wake up at the same time every day, even on weekends and during the day.

Will it be for business? Then make a schedule for building {#blank#}2{#/blank#} app. You need plenty of time for researching and getting enough information {#blank#}3{#/blank#} you can build your app.

    Now you're ready {#blank#}4{#/blank#} (start) the app. Building an app is like a puzzle with many different parts, you can build it yourself or find a friend to help you. There are many websites and {#blank#}5{#/blank#} (video) which can teach you to build one. Some websites provide app developers {#blank#}6{#/blank#} "building blocks". As you build one, you pick blocks from the websites and put {#blank#}7{#/blank#} (they) in your app.

    After you build your app, you need to check it {#blank#}8{#/blank#} (careful). Look for bugs. Most apps have several problems to fix. Show your app to people and ask their opinions. Make sure everything {#blank#}9{#/blank#} (work) before letting people download it. There are so many tools that can help you build apps. Having the right tools will make the work much {#blank#}10{#/blank#} (easy). Now almost anyone can make a new app.

    What does it mean to be green? "Green" is more than a color.
