问题 问答题 简答题

自2012年7月1日起,全国绝大部分省市开始实行居民阶梯电价。共分三档,第一档为基础电量,价格不变,第二档每度涨5分,第三档涨3角。其具体内容包括:第一阶梯为基数电量,此阶梯内电量较少,电价较低;第二阶梯电量较高,电价较高一些;第三阶梯电量更多,电价更高。这不仅督促市民更加合理用电,更提升了节能家电的关注度,刺激了销量,同时也加速了市民家里“电老虎”的淘汰,节能型产品将再次掀起一波销售高潮。结合材料,分析实行阶梯电价可能对居民生活、生产产生的影响。

    "In only six days I lost seven pounds of weight."

     "Two full inches in the first three days!"

     These are the kinds of statements used in magazine,newspaper, radio and television ads, promising

new shapes and new looks to those who buy the medicine or the device. The promoters of products say

they can shape the legs, slim the face, smooth wrinkles, or in some other way to add to beauty or

desirability.

     Often such products are nothing more than money-making things for their promoters. The results they

produce are questionable, and some are dangerous to health.

     To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA (Food and Drug

Administration)can require proof under the Food, Drug, and Cosmetic Act that is safe and effective

before it is put on the market. But if the product is a device, FDA has no authority to require

premarketing proof of safety or effectiveness. If a product already on the market is a danger to health,

FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal

action, including seizure (查封) of the product.

     One notable case a few years ago involved an electrical device called the Relaxacisor, which had

been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through

contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds

that it was dangerous to health and life.

     Obviously, most of the devices on the market have never been the subject of court proceedings (法

律诉讼), and new devices appear continually. Before buying, it is up to the consumer to judge the safety

or effectiveness of such items.

3. FDA can ask for the proof of safety and effectiveness of a product           

A. if it is a drug
