Taking a taxi in a certain Eastern European country can be a shocking experience. {#blank#}1{#/blank#} is said that some taxi drivers have metal wires stuck into the passenger seats. And {#blank#}2{#/blank#} a button is pushed, the seat will give you {#blank#}3{#/blank#} electric shock. These taxi drivers don't do this {#blank#}4{#/blank#} fun. They do it to tourists {#blank#}5{#/blank#} argue about the ridiculous(可笑的,荒谬的) fares they charge. Some drivers charge as much {#blank#}6{#/blank#} ten times the legal fare.
They have a secret switch which makes the meters run faster. If the tourists refuse to pay, {#blank#}7{#/blank#} are really in for a shock.
In one case, a German woman had no {#blank#}8{#/blank#} (choose) but to pay $120 for a $ 20 ride from the airport. She said that she was "really taken for a ride," but what could she do? Besides the electric shock, she {#blank#}9{#/blank#} (threaten) with physical violence. She has only one piece of advice for tourists, “Take the bus {#blank#}10{#/blank#} stay at home.”

A small group of people around the world have started implanting(移植) microchips to link the body and the computer.
Mr. Donelson and three friends, who had driven 100 miles from their homes in Loockport, New York, to have the implants put in by Dr. Jesse Villemaire, whom they had persuaded to do the work, are part of a small group, about 30 people around the world, who have independently put in microchips into their bodies, according to Web-based reports.
At a shop William Donelson was having a four-millimeter-wide needle put into his left hand. “I'm set,”he said with a deep breath. He watched as the needle pierced(刺穿) the fleshy webbing between his thumb and a microchip was set under his skin. At last he would be able to do what he had long imagined: strengthen his body's powers through technology.
By putting the chip inside—a radio frequency identification device (RFID)—Mr. Donelson would have at his fingertips the same magic that makes safety gates open with a knock of a card, and bridge and tunnel traffic flow smoothly with an E-Zpass. With a wave of his hand he plans to connect with his computer, open doors and unlock his car.
Implanting the chip was relatively simple task but very meaningful to Mr. Doneselson, a 21-year-old computer networking student so interested in the link between technology and the body that he has data-input jacks(数据输入插空) inside his body. They might lead to an imagined future when people can be connected directly into computers. His new chip is enclosed in a glass container no bigger than a piece of rice and has a small memory where he has stored the words “Technology”.
Some doctors have done the piercing in people's homes, and others have implanted chips in their offices after patients signed forms showing the fact that long-term studies have not been done on their safety. Piercers treat the implants much like any other medical operation steps, instructing people to keep the site dry, and advising them that swelling and redness should last a week.

Most drinks stating that they are fruitflavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.
“Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be nonexistent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. {#blank#}1{#/blank#} It will increase profits, and consumers won't always realize they are being tricked.”
Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberryflavored products sold in stores. {#blank#}2{#/blank#} Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.
{#blank#}3{#/blank#} Let's take jam as an example. Some strawberryflavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.
{#blank#}4{#/blank#} Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. {#blank#}5{#/blank#} Unfortunately, it is also legal and widespread,” Tokelove said. “It's time to take measures to protect the consumers' rights.”
A. The products which contain real fruit are popular with people.
B. Even products advertised as more natural often contained no fruit.
C. They found that about 60 percent of them didn't contain any fruit at all.
D. If companies can cut their costs by using flavoring, they are likely to do so.
E. It is important and necessary to demand a small amount of flavoring in the products.
F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.
G. The Food Commission suggested all flavors used in a product should be listed on the packaging.
