A new study found that Americans throw away {#blank#}1{#/blank#} (几乎) 37 billion kilograms of food a year, and about half of all Americans do not realize that food {#blank#}2{#/blank#} (浪费) is a problem in the US.

    The most common reason for throwing away food was about food {#blank#}3{#/blank#} (安全). 68％of respondents said they threw away food after the package date has passed. They believe it {#blank#}4{#/blank#} (减少) the chance of illness carried by food. 59％believe it is {#blank#}5{#/blank#} (必要的) to throw away some food for fresh and delicious meals.

Because most respondents {#blank#}6{#/blank#} (考虑) throwing away food after the sell-by or use-by date, the researchers suggested, “Clean up your fridge in time and don't store food {#blank#}7{#/blank#} (除非) some special situations. Before you buy, always remember to {#blank#}8{#/blank#} (比较) the dates·"

    The study's co-authors also took actions. They are using the {#blank#}9{#/blank#} (结果) of the study to develop a smart phone app to make a {#blank#}10{#/blank#} (记录) of how much food is thrown away more accurately.

    Recently, more and more students have {#blank#}1{#/blank#}（意识到）that it is necessary to learn to {#blank#}2{#/blank#}（管理）the time well. Some students think it's a good idea to make a list of today's {#blank#}3{#/blank#}（任务）. Teachers point out if students are good at  {#blank#}4{#/blank#}（比较） their own experience with other's good ways, they will find it easy in the {#blank#}5{#/blank#}（接下来的） days.

    David, a student from Class 9, says, "I don't think doing homework until{#blank#}6{#/blank#}（ 午 夜 ）is good for my study. And in my{#blank#}7{#/blank#}（观点）, though there is always much homework, we should do it by {#blank#}8{#/blank#}（我们自己）. To be {#blank#}9{#/blank#}（诚实的）is the most important, or we'll lose more. If we pay attention to these basic {#blank#}10{#/blank#}（规则）, we will certainly make great progress."
