“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 such products say they can shape the legs, slim the face, smooth wrinkles, or in some other way 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(證明) under the Food, Drug, and Cosmetic Act that it 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(法律訴訟), and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.

1.It can be inferred that the ads mentioned in the text are ________.

A. objective   B. costly   C. unreliable   D. illegal

2.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.

3.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

4.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

5.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

閱讀下面短文,從每題所給的四個(gè)選項(xiàng)(A,B,C和D)中選出最佳選項(xiàng)。

  Rex White knows too many seamen's stories to want to add to them. Besides, this happened on land. It happened in Lytham, a town on the River Ribble, near the place where the river flows into the Irish Sea. The shape of the trees along the Lytham beach road is proof(證明)of the great strength of the wind which comes in off the sea. It blows hard across the grass, the car parks and the open road beside the river, and there's nothing to stop it.

  Rex was a ship's pilot. It was his job to guide ships up the river, between banks of sand, into the port of Preston. Mr White lived in a village some kilometres from the coast, so he had to drive to Lytham and leave his car in one of the car parks beside the river. Then he rowed (劃船) out to the pilot boat , and waited for the particular ship that it was his duty to guide.

  Early one morning, Mr White returned to Lytham from a night on duty, to find that he could not start his car. He had driven from his village the evening before and had left his car in the car park as usual. He had rowed out to the pilot boat and gone on board the S. S. Kilkenny, which was on her way from Ireland. Then, in the early hours of the following morning, he had returned to Lytham in the pilot boat, expecting to drive home to have a cup of hot chocolate and a warm bed. But whatever he did, he could not get the engine to start.

  It was a cold and windy night; there was no one about, and there was no garage open to which he could turn for help. He was just about to give up and spend the rest of the night on the back seat of the car when he had a bright idea. He pushed the car round so that it was facing in the direction of the wind, opened all four doors, pushed it along a short way, and then jumped in. The doors acted like sails(帆), and in no time the wind had taken him right out of the car park, and away down the beach road. When he tried the starter switch (開關(guān)) once more, the engine roared (咆哮) to life immediately. All he had to do then was to stop the car and shut the doors.

  He went to bed later than usual, but he didn't go without his cup of hot chocolate. Mr White was not a seaman for nothing.

1.This passage is about ________.

[  ]

A.how Mr White got his car to start on a cold and windy morning

B.what the weather was like in Lytham

C.what happened to Mr White one cold end windy night

D.how Mr White did his job and enjoyed his life

2.We can tell how strong the wind is along the beach road ________.

[  ]

A.from the way the river flows into the Irish Sea

B.by looking at the shape of the trees

C.from the fact that the open road is beside the river

D.by taking this story as a real one

3.His“bright idea”was to ________.

[  ]

A.push the car round so that it was out of the wind

B.put up sails on the car and let it go with the wind

C.open the doors and get the wind to push the car along

D.push the car a short way and then jump in

4.“Mr White was not a seaman for nothing”(in Paragraph 5) means that ________.

[  ]

A.Mr White was a seaman who was good at everything

B.Mr White had other things than a cup of chocolate for what he had done

C.Mr White was an experienced and clever seaman

D.Mr White got something for being a seaman
