action is taken. They used electronic ways to track the movement of the powerful fish from the
Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi
and sandwiches with tuna worldwide are more dangerous than anyone has imagined.
The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as
700kg. A good one can fetch as much as ? 52,000 in the Tokyo fish markets. "In my lifetime,
we"ve brought this big fish to the doorstep of death in the western Atlantic Ocean," said Barbara
Block of Stanford University in California. "The electronic way of tracks provides the best scientific
information we"ve ever had to manage these tuna and we must, as an international community, start
to act actively to make sure of the future of this fish. "
Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There
are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have
pushed further offshore in search of deep ocean fish. Tuna-in the Mediterranean and Japan-have
been under increasing pressure for years. The International Commission on the Conservation of
Atlantic Tuna has tried to manage the fish since 1969.There are two populations: a western one
that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches
are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew
whether the limits worked.
So Professor Block and her team placed tracks on hundreds of the fish and tracked them to
depths of more than 900 metres and on journeys of thousands of miles, measuring the movement,
body and water temperatures. "There are two ways to save the Atlantic bluefin tuna-protect them
in their production grounds and in their feeding grounds," Prof. Block said. "This will need immediate
action in both the central Atlantic, to reduce the loss of the big fish while hunting, and in the Gulf of
Mexico and Mediterranean, where tuna produce as separate populations. "

they cannot see clearly what has happened, a small German company is quietly pleased.
For Cairos Technologies, mistakes made by referees are the kind of advertising that money cannot buy. The company has developed a tiny chip(芯片) that fits inside a football and determines whether the ball
has crossed the goal line, by being able to discover its exact location on the field. The world football
organization, FIFA, has shown interest in the technology. It is very possible that the new technology will
be used in the 2006 World Cup in Germany.
"We"ve been testing the technology at the main soccer stadium in Nuremberg for some time and more
recently in an under-17 FIFA Cup in Peru," said Gunter Rohmer, a director of the company. "The
technology has performed well, and we"re pretty optimistic that it will be used at the games in Germany
next year."
The chip only weighs 12 grams, and is placed in the center of the football. It sends 2,000 signals a
second to a receiver network of 12 antennas(天线), placed around the field. The receivers then send
information about the ball"s location to a central computer, and because it works in real time, it can
immediately tell the referee whether a goal has been scored. The chip even can tell when the ball crosses
the line in mid-air. Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive. Germany sports-wear giant Adidas is also optimistic about using this kind of chip
in other ball sports.
FIFA aims to test the technology later this year at another game in Japan before deciding whether or
not to introduce it in all 12 stadiums in Germany for next year"s World Cup.

D. Referees" mistakes will be of great help for the sale of Carlos Technologies" new product
B. advice given by someone
C. supplying food to customers

The $11 billion self-help industry is built on the idea that you should turn negative thoughts like "I never do anything right" into positive ones like "I can succeed." But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking? Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are. The study"s authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing(引用) older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better. If you tell your depressed friend that he has the potential of an Einstein, you"re just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays opposing funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written. In this experiment, Wood, Lee and Perunovic measured 68 students" self-esteem. The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, "I am lovable." Those with low self-esteem didn"t feel better after the forced self-approval. In fact, their moods turned significantly darker than those of members of the control group, who weren"t urged to think positive thoughts. The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation (静思) techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic perspective. Call it the power of negative thinking. | |||

阅读理解 Even plants can run a fever, especially when they"re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adopting the infrared(红外线)scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide(***虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don"t have pest problems. Even better, Paley"s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a colourcoded map showing where plants were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would. The bad news is that Paley"s company closed down in 1984, after only three years. Farmers resisted the new technology and longterm backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago. 1. Plants will send out an increased amount of heat when they are________. A. facing an infrared scanner B. sprayed with pesticides C. in poor physical condition D. exposed to excessive sun rays 2. In order to apply pesticide spraying precisely, we can use infrared scanning to________. A. estimate the damage to the crops B. draw a colourcoded map C. measure the size of the affected area D. locate the problem area 3. Farmers can save a considerable amount of pesticide by________. A. resorting to spotspraying B. transforming poisoned rain C. consulting infrared scanning experts D. detecting crop problems at an early stage 4. The application of infrared scanning technology to agriculture met with some difficulties-________. A. its high cost B. the lack of official support C. the lack of financial support D. its failure to help increase production 5. Infrared scanning technology may be brought back into operation because of________. A. full support from agricultural experts B. growing concern about the excessive use of pesticides on crops C. the forceful promotion by the Department of Agriculture D. the desire of farmers to improve the quality of their produce |
