“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 good 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 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 Drug Administration) can require proof 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 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.The author intends to______.

A. make consumers aware of the promoters’ false promise

4.Which of the following is true according to the text?

c. New products are more likely to be questionable.

D. The production of a device must be approved by FDA.

“Iris scan (虹膜扫描), please,” the bank’s computer voice tells you. You step up and the computer reads your eye, comparing it to the stored file it has of your iris. The images had better match---otherwise, you won’t be able to get your money.

Iris scanning and other technologies, such as fingerprint and voice scanning, have appeared in many science fiction movies in the past. Today, these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics(生物测定学), a fast developing area of automatic personal identification technology. Basically, biometrics uses various ways to verify a person’s identity, based on the individual’s unique characteristics, including fingerprints, signature, and so on.

Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember, forget, lose, or steal.

The voice scan is the simplest and most affordable form of biometrics. It only requires a computer, a microphone, and the correct software. The software records a subject’s voice and then compares it to a stored voice sample for identification purpose.

For additional safety, fingerprint and handprint scans can also be employed. Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand.

In April 2014,the world's oldest known message in a bottle was discovered floating in the Baltic Sea. It had spent 101 years lost in the ocean!The message was finally sent to the author's granddaughter.

A German fisherman named Konrad Fischer found the brown bottle near Kiel,Germany. He said he nearly threw the bottle back into the water after pulling it out of a fishing net. Then he noticed something inside.

The bottle in good condition contained a Danish postcard with two German stamps,dated May 17,1913. Although dampness had made most of the writing illegible(字迹模糊的),the readable part of the message asked whoever found it to return it to an address in Berlin. It even contained two stamps to pay for postage.

From the address,researchers found that the postcard was written by a man named Richard Platz,who was 20 years old when he wrote the message. While he was hiking on the Baltic coast with a nature appreciation group,he threw the bottle into the sea. Then the researchers began a search for any living relatives of his. Sure enough,they were able to find his 62-year-old granddaughter,Angela Erdmann,who still lives in Berlin.

“It was almost unbelievable,”Erdmann said upon being presented with her grandfather's bottle and message.“That was a pretty moving moment. Tears rolled down my face."

Erdmann never knew her grandfather,who died in 1946,but says that the discovery of the bottle has made her want to learn more about him.

The bottle remained on display at the International Maritime Museum in Hamburg until May 1.After that,the researchers examined the postcard and tried to figure out the meaning of the rest of the message.

I am trying to muster (鼓起) the courage to toss_away my mobile phone to enjoy a more peaceful and ring-free life.

Can you imagine not having your mobile phone? In our high-tech, in-a-hurry age, a cell-free life is a hard concept to swallow. Our mobile phones can now access the Internet, and many people feel the need to express their every thought on their blog pages. If I gave up my cell-phone, people would think I was mad.

I wish I had the strength to toss away my technology. I have an office phone, a home phone, an e-mail and if people want to contact me, they can. If I'm out, people can leave a message. Do they really need to find me 24/7? However, I'm a bit like Frodo in the movie Lord of the Rings. The power of the ring is too strong and I can't let it go.

Mobile phones have become necessary tools in our busy life. For most people, they hold all contacts and many of us don't write up address books any more. The latest phones carry our music, pictures, movies and everything else. We feel lost without this device and when we do misplace it, we feel cut off from our fellow.

"Where have you been?" said a friend, who saw me a week after I lost my cell-phone, "I tried calling you, but you disappeared. You disappeared off the face of the Earth." See, when you don't have a mobile phone, you don't exist.

I'm not really going to toss my mobile phone away, in fact. We humans are such social animals and mobile phones serve us well. So in 2009, I've decided not to serve my mobile phone. Like all machines, I can always turn it off.
