Sports shoes that out whether their owner has enough exercise to warrant time in front of the television have been devised in the UK.

The shoes―named Square Eyes―contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.

The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University to London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”

Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.

Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.

Existing pedometers （计步器） normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”

71．According to Swan, the purpose of her design project is to ________.

A．keep a record of the steps of the wearer

B．deal with overweight among teenagers

C．enable children to resist the temptation of TV

D．prevent children from being tricked by TV programs

72．Which of the following is true of Square Eyes shoes?

A．They regulate a child’s evening TV viewing time.

B．They determine a child’s daily pocket money.

C．They have raised the hot issue of overweight.

D．They contain information of the receiver.

73．What is stressed by health experts in their suggestion?

A．The exact number of steps to be taken.

B．The precise number of hours spent on TV.

C．The proper amount of daily exercise and TV time.

D．The way of changing steps into TV watching time.

74．Compared with other similar products, the new design ________.

A．makes it difficult for lazy teenagers to cheat

B．counts the wearer’s steps through shaking

C．records the sudden movement of the wearer

D．sends teenagers’ health data to the receiver

75．Which of the following would be the best title for the text?

Education cuts(削减) have become routine (惯常的) over the past few years, which has made it difficult for students to learn. The results of a survey of 1,850 Los Angeles County high school students show just how much the cuts are affecting students.

Because of teacher layoffs (解雇), class sizes at some high schools have risen to 50 students — even in math and English classes. Some 37 percent of students report that they sometimes don’t have a desk to sit at. Sixty-seven percent say crowded classrooms make them feel the teachers don’t have enough time to teach, and 30 percent say they’ve not been able to join in a program because it’s no longer offered at their school.

At a time when technology is an important skill, 52 percent of students say there aren’t enough computers. Or they’re often broken, and there’s no one to fix them. Fifty-one percent say they’ve had to share textbooks with a classmate because there aren’t enough copies to go around. Fifty-seven percent say they’ve had to copy information because their school doesn’t have enough paper to make copies.

“We have only one science teacher for the entire(整个的) high school,” writes Felix Ruano, a 16-year-old student. He goes on to describe how that teacher, who is only qualified to teach chemistry, is teaching physics — or, at least, is trying to do so. “He shows physics videos and we teach ourselves from our textbook,” says Ruano. And, as has been seen elsewhere, “all but one of the restrooms” at Ruano’s school “have been closed because we don’t have enough people to clean them.”

Ruano notes that though faced with the challenges, 97 percent of students say they plan to go to college. But without “properly trained teachers and the best resources,” says Ruano, it’s not likely that every student will achieve that goal. “Unless schools fix these problems,” he says, “students could lose hope.”

Kalle Lasn was in a supermarket parking lot one afternoon when he had an experience that changed his life．In order to shop at the store, he needed to put money into the shopping cart to use it．Annoyed that he had to "pay to shop," Lasn jammed the coin into the cart so that it wouldn't work．It was an act of rebellion—the first of many—for Lasn．

Born in Estonia, Kalle Lasn moved to Australia as a young man and then later to Japan, where he founded a marketing research firm in Tokyo．Eventually, Lasn moved to Canada and for several years produced documentaries （纪录片） for public television．In the late 1980s, Lasn made an advertisement that spoke out against the logging industry and the deforestation going on in the Pacific Northwest．When he tried to show his ad on TV, though, no station in this area would give him airtime．In response, Lasn and a colleague founded Adbusters Media Foundation, a company for the "Human right to communicate．

Adbusters produces magazine, newspaper, and TV ads with a social message．Many use humor and irony to make their points: In one, for example, a man chain smokes a brand of cigarettes called "Hope"．In another, a child is dressed in an outfit used in fast-food ads．Next to the child is a note from its mother telling the restaurant to leave her child alone．

Adbusters also has a magazine and a web site, the Culture Jammers Network, whose members include students, artists, and activists as well as educators and businesspeople interested in social change．Many of these "culture jammers" are working to raise awareness about different social issues by hosting events like "Buy Nothing Day" , " No Car Day" and "TV Turnoff Week" ．Lasn and his partners hope these events will encourage people to think about questions such as;

·What kinds of things are we being encouraged to buy by the media?

·Should cars be our primary means of transportation?

·How are television and radio being used now? How could we be using them?

Some culture jammers are using other methods to challenge how people think．Some pretend to be shoppers．They move items in stores from one shelf to another making it difficult for people to find things easily．Other culture jammers break into large company well sites and jam them so that they become unusable．The goal in both cases ia to prevent "Business as usual" and to gel people to ask themselves questions such as "Why am I shopping here?" or "Why should I buy this product?"

Lasn and members of the Culture Jammers Network want to make people aware of social issues, but they also believe it's important to think of solutions, too．"A lot of people tell you everything that's wrong but they never say much about how to fix these problems," says Lasn．"But there is plenty we can do．If you start despairing, you have lost everything．"

Though many TV stations still won't show Adbusters' " uncommercials" , some cable TV stations have started to．People all over the world have joined the Culture Jammers Network and are doing their part to promote social change．

A．Smoking can help to remove your worries and make you hopeful．

B．Hopefully, the bad taste of the cigarette can help you to quit smoking．
