(2009·山东高考)“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 (证明)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.

语篇解读:本文剖析了一下广告华丽语言背后的真相，提醒消费者要注意广告中华而不 实的宣传和承诺。

26．It can be inferred that the ads mentioned in the text are________.

A．objective B．costly C．unreliable D．illegal 解析：推理判断题。文章提出许多媒体上的广告都含有虚假成分，夸大其词，而 事实上广告中的产品往往不具有其所宣称的效果。文章第四段提到这些产品的效 果是值得怀疑的，不可靠的甚至是危险的。objective“客观的，不带偏见的”； costly“昂贵的，代价高的”；unreliable“不可靠的”；illegal“不合法的，违法 的”。 答案：C

27．Which of the following is TRUE according to the text? A．The court is in charge of removing dangerous products. B．New products are more likely to be questionable. C．The production of a device must be approved by FDA. D．The promoters usually just care about profits.

解析：事实细节题。第四段第一句话说“通常这些产品对推销者来说只是挣钱的 工具”，显然D项“推销者通常只关注利益”最符合文意。A，法庭负责召回危 险产品，错在这并非法庭的责任；B，新产品更值得怀疑，在文中没有信息支 持；C，设备的生产必须经过食品与药品管理局的批准，错在并非设备的生产。 答案：D

28．FDA can ask for the proof of safety and effectiveness of a product________. A．if it is a drug B．if it is a device

C．if its consumers make complaints

D．if its distributors challenge FDA's authority

解析：事实细节题。从文章第五段第二句话可知A项正确，如果是药物的生产，

则必须向FDA证明其安全性和有效性。 答案：A

29．The Relaxacisor is mentioned as________.

A．a product which was designed to produce electricity B．a product whose distributor was involved in a legal case C．a successful advertisement of a beauty product D．an example of a quality beauty product

解析：事实细节题。文章倒数第二段提到的这个案例与上一段最后一句话紧密相 连，对其进行举例说明，即如何采取法律措施，第三句话说FDA对the Relaxacisor的发行商采取了法律措施，责令其停止销售，所以答案为B。A项错

在这不是一个用来发电的产品；C项中的successful明显错误；D项说这是一个优 质美容产品的典范，错误。 答案：B

30．The author intends to________.

A．make consumers aware of the promoters' false promises B．show the weakness of the law on product safety C．give advice on how to keep young and beautiful D．introduce the organization of FDA

解析：主旨大意题。作者通过对一些虚假广告问题的分析，提醒消费者关注生产 者对产品的不实宣传和虚假承诺，避免上当受骗，故A项最为恰当。 答案：A

C
