题目内容

【题目】下列地点中，其位置符合东半球、北半球、低纬度三个条件的是（ ）

A. 165°E，20°N B. 21°W，5°N C. 15°W，25°S D. 15°W，25°N

【答案】D

【解析】

因为东西半球的界线是20°W，160°E, 西经20°（W）以东，东经160°（E）以西的在东半球；东经160°（E）以东，西经20°（W）以西的在西半球——即经度小于20°的在东半球，大于160°的在西半球，其余的东经在东半球，西经在西半球。赤道以北（北纬，N）的北半球，以南（南纬，S）的在南半球。

纬度0°－30°在低纬度，30°－60°在中纬度，60°－90°在高纬度。所以A．165°E，20°N ——西半球，北半球，低纬度；错。B．21°W，5°N ——西半球，北半球，低纬度；错。C．10°W，25°S ——东半球，南半球，低纬度；错。D．15°W，25°N——东半球，北半球，低纬度；正确。故本题选D。

【题目】Where does your food come from? How is it made? These days, many people worry about food safety. But food safety is not a new worry. In 1906, Upton Sinclair wrote The Jungle. The book is the story of a poor family in Chicago. It is also about the dangerous ways that food was prepared. People were so worried that the U．S. started testing food.

These days, most food in the world is safe. Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But it's more important to make sure the rules are followed. A good food safety system keeps people safe. It also helps them eat healthy food. Labels(标签) on food give people important information. Then they can make good choices about their food.

Although food safety systems usually work, there can be problems. Sometimes mistakes are made. For example, a truck might carry eggs and then ice－cream. The ice－cream could make people sick when the truck isn't cleaned before carrying it. Other problems are not mistakes. Sometimes companies break rules to make_more_money. When this happens, people don't know if their food is safe.

As we all know, food is closely related to our daily life. We should take action to make food safer!
