What's even more surprising is that the food thrown away in places like the United States and Europe could feed all those hungry people! Why do we waste so much food? Sometimes, bugs damage(虫子损害)the food before it can be picked, or it is discarded by stores because of not looking nice.Food can also go bad in stores or at our homes if we buy too much or forget to eat it.Sometimes,we cook more food than we can eat and end up throwing it away. To solve the food waste problem,we're supposed to make some changes.In places where people are still developing better ways to farm, improving how food is picked, stored, and transported can save a lot of food.In places like the United States,we need to make people come to realize how much food they're wasting.Some restaurants have started serving smaller meals and reminding people to take their leftovers home instead of throwing them away. With not enough land, water, and energy for everyone, it's important to think about how we use food.As more people live on Earth,we need to stop wasting food and take action to use it better.If we all do our part,we can make a big difference in reducing food waste. 任务一：阅读理解。 ( )1.What can we know from paragraph 1?

Others leave the water running or lights on. In order to solve the problems,we should tell them the importance of environmental protection.For example,we can put up some posters and make some rules to stop littering.We should also do the cleaning regularly.Besides,we will encourage students to save water.What's more,we need to remind each other to turn off the lights before leaving. It is important to build a green school because a perfect environment for study and rest makes everyone happy and comfortable.I believe our school will become better and better as long as we keep trying. 学科网（北京）股份有限公司 $
