Question

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released five simple rules for preparing food in a safe way. They call these rules the “Five Keys to Safer Food”.
Key 1: Keep clean.
People should wash their hands often — before touching food and while they are preparing food. People should wash all surfaces and equipment used for preparing food.
Key 2: Separate raw and cooked.
Raw foods should not touch prepared foods.
Key 3:
People should cook eggs and meat especially carefully. These foods may carry more micro-organisms (微生物) than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.
Key 4: Keep food at safe temperatures.
When people finish eating, they should keep the left food in a refrigerator below 5℃and shouldn't store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms.
Key 5: Use safe water and raw materials.
Damaged or old food may develop harmful chemicals as it gets older.
A. Cook completely.
B. This key tells about the importance of washing.
C. Eat healthily.
D. They can live where we make food.
E. People should use safe water and choose fresh foods.
F. They cannot grow as quickly in a very hot or very cold environment.
G. People should use separate equipment and tools for touching and preparing raw foods.

Answer 1

【答案】B；G；A；F；E
【解析】分析】本文是一篇说明文，食品安全问题是全世界各地区的一个问题。文章讲了使实物更安全的五个关键。
（1）考查对上下文的理解和推理判断能力。根据空后“People should wash their hands often — before touching food and while they are preparing food”人们触碰食物以前和在准备食物期间，应该经常洗他们的手。可知此处在说“洗的重要性”。故选B。
（2）考查对上下文的理解和推理判断能力。根据空前“ Raw foods should not touch prepared foods. ”未加工的食物不应该和准备好的食物放在一起。可知此句意思是：应该把未加工的和已经准备好的食物分开放。可知G项符合题意。
（3）考查对上下文的理解和推理判断能力。此处是小标题题。根据空后“People should cook eggs and meat especially carefully.”人们应该特别小心地煮鸡蛋和肉。可知A项“Cook completely彻底地煮”符合题意。
（4）考查对上下文的理解和推理判断能力。根据空前“ut temperatures above 60℃ or below 5℃ control the growth of micro-organisms.”60度以上或5度以下的温度控制微生物的生长。可知F项“他们在非常冷或非常热的环境下不能快速生长。故选F。
（5）考查对上下文的理解和推理判断能力。根据空后“Damaged or old food may develop harmful chemicals as it gets older.”，损坏或旧的食物可能会发展成有害的化学物质。可知此空的意思是：应该用安全的水和新鲜的食物。E项符合题意。
