Land is used to grow it, water is used to produce it, and fuel is used to move it to shops. When edible food is thrown away, the resources used along this journey are wasted too. The environmental cost begins on farms. Growing vegetables, keeping animals and processing grain all require water and energy. Then food may travel through factories, cold stores and delivery vehicles before it reaches a kitchen. Each stage uses resources and can create pollution. This does not mean that people should stop eating varied food; it means that food should be treated as something valuable. Households can reduce the problem through simple planning. A shopping list helps people buy what they can use. Food that will not be eaten soon can be stored correctly or frozen. Leftover rice or vegetables can become part of another meal instead of being forgotten at the back of a fridge. These choices save money as well as resources. Restaurants, shops and families also have a role. They can offer suitable portions, share safe extra food and teach children to distinguish between food that is no longer safe and food that is simply imperfect in appearance. Reducing food waste will not solve every environmental problem, but it is a practical way to respect the land, water and energy that support daily life. 6. Why does throwing away edible food waste resources? A. Food needs land, water and fuel before reaching plates B. Food is always kept in cold stores for weeks C. Families must grow every kind of food at home D. Restaurants everywhere use more water than local farms 7. What can a shopping list help households do? A. Cook every meal with only frozen vegetables B. Buy only what they are able to use C. Make delivery vehicles use much less fuel D. Decide which farms should grow more grain 8. What does the word “imperfect” probably mean in paragraph 4? A. Not safe to eat under any condition B. Not available in a local market C. Not suitable for cooking in a restaurant D. Not attractive or regular in appearance 9. What can be inferred from the passage? A. Reducing food waste remains useful without solving every problem B. Only restaurants can protect resources through careful food planning C. Frozen food always causes more pollution than fresh food D. Families should avoid eating vegetables with unusual shapes 10. Which is the best title for the passage? A. Why Food Should Be Transported More Quickly B. The History of Modern Food Storage Methods C. Food Waste and Its Environmental Cost D. How Restaurants Design Their Large Food Portions 三、完形填空 On Sunday, Mei decided to organize her wardrobe before the new season. She found shirts she still wore, a small coat and several old T-shirts.

Food does not appear on a plate by magic. Land is used to grow it, water is used to produce it, and fuel is used to move it to shops. When edible food is thrown away, the resources used along this journey are wasted too. The environmental cost begins on farms. Growing vegetables, keeping animals and processing grain all require water and energy. Then food may travel through factories, cold stores and delivery vehicles before it reaches a kitchen. Each stage uses resources and can create pollution. This does not mean that people should stop eating varied food; it means that food should be treated as something valuable. Households can reduce the problem through simple planning. A shopping list helps people buy what they can use. Food that will not be eaten soon can be stored correctly or frozen. Leftover rice or vegetables can become part of another meal instead of being forgotten at the back of a fridge. These choices save money as well as resources. Restaurants, shops and families also have a role. They can offer suitable portions, share safe extra food and teach children to distinguish between food that is no longer safe and food that is simply imperfect in appearance. Reducing food waste will not solve every environmental problem, but it is a practical way to respect the land, water and energy that support daily life. 6. Why does throwing away edible food waste resources? A. Food needs land, water and fuel before reaching plates B. Food is always kept in cold stores for weeks C. Families must grow every kind of food at home D. Restaurants everywhere use more water than local farms 7. What can a shopping list help households do? A. Cook every meal with only frozen vegetables B. Buy only what they are able to use C. Make delivery vehicles use much less fuel D. Decide which farms should grow more grain 8. What does the word “imperfect” probably mean in paragraph 4? A. Not safe to eat under any condition B. Not available in a local market C. Not suitable for cooking in a restaurant D. Not attractive or regular in appearance 9. What can be inferred from the passage? A. Reducing food waste remains useful without solving every problem B. Only restaurants can protect resources through careful food planning C. Frozen food always causes more pollution than fresh food D. Families should avoid eating vegetables with unusual shapes 10. Which is the best title for the passage? A. Why Food Should Be Transported More Quickly B. The History of Modern Food Storage Methods C. Food Waste and Its Environmental Cost D. How Restaurants Design Their Large Food Portions 【答案】6.A 7.B 8.D 9.A 10.C 【导语】本文是一篇说明文，介绍食物浪费带来的环境负担。文章从食物生产、运输和冷藏所消耗的土地、水和能源讲起，再说明家庭可以通过列购物清单、正确储存和利用剩余食材减少浪费，最后指出餐馆、商店和家庭都应共同承担责任。 【详解】 6. 考点：细节理解题。根据“Land is used to grow it, water is used to produce it, and fuel is used to move it to shops”(种植食物需要土地，生产食物需要水，将食物运到商店需要燃料)可知，食物到达餐桌前需要多种资源。故选A。 7. 考点：细节理解题。根据“A shopping list helps people buy what they can use”(购物清单帮助人们购买能够用完的东西)可知，购物清单能帮助家庭按需购买。故选B。 8. 考点：词义猜测题。根据“distinguish between food that is no longer safe and food that is simply imperfect in appearance”(区分不再安全的食物和只是外观不完美的食物)可知，imperfect意为“外观不美观或不规则的”。故选D。 9. 考点：推理判断题。根据“Reducing food waste will not solve every environmental problem, but it is a practical way”(减少食物浪费不能解决所有环境问题，但它是一种实际可行的方式)可推知，减少食物浪费虽不能解决全部问题，仍然有价值。故选A。 10. 考点：标题归纳题。根据“Food waste is often discussed as a household problem, but it also affects the environment”(食物浪费常被视为家庭问题，但它也会影响环境)以及全文内容可知，文章说明食物浪费的环境代价及减少方法。故选C。 三、完形填空 On Sunday, Mei decided to organize her wardrobe before the new season.
