TEXT A "I’m SORRY. "For days that’s been about all Japan has heard from its Olympic athletes. Those were the first words uttered by a young swimmer after competing in the 400-m individual-medley swimming event, a difficult exercise that takes more than 4 1/2 minutes to complete and requires four different strokes. Because her event took place on the opening day of Sydney 2000, her performance was considered especially significant for the fortunes of the nation. But with all of Japan watching, Yasuko Tajima fell short. Never mind that she earned a silver medal. "How disappointing," she said. "Next time I will win the gold." There is a unique form of pressure on Japan’s athletes. Competitors from every country face enormous expectations to win , to make the years of hard work and training pay off, to achieve greatness on the preeminent world stage. American cyclist Lance Armstrong ,winner of two consecutive Tour de France races after surviving a contest with cancer, noted last week that, "If I loses the Olympics, they’ll say, ’I thought he was supposed to be a good cyclist.’" "But whereas failure to win gold might cost Americans a fat endorsement contract, for Japanese a disappointing performance is even more disastrous, as individual failure is somehow wrapped up with a sense of national identity. "For non-Japanese, it’s very peculiar for athletes to say they are sorry. "says Mitsunori Urushibara, a professor of sports philosophy at Shikoku Gakuin University. "Failure is never just an individual matter in Japan. Athletes always face the terror of being excommunicated from the group." Understanding the culture in which Japanese athletes compete makes watching their defeats all the more painful. The agony of gymnast Naoya Tsukahara, whose hopes for an individual all-around medal were dashed last Wednesday when he inexplicably fell off the pommel horse, was obvious as he seemed to sleepwalk through his other events. His body was limp, his expression blank. "I didn’t want to disgrace my nation," he said. Another young swimmer, Tomoko Hagiwara, climbed out of the pool after finishing seventh in her 200-m individual-medley qualifying heat last Monday, her shoulders hanging downward, her head tilted downward. "What was the cause of your poor performance" snapped a reporter for NHK, the national TV network. Hagiwara answered that she didn’t shift smoothly between strokes and that her turns were poor. "Please remember those points and try to do better in the next race," the reporter lectured. "You feel as ff everyone in Japan feels ashamed of you, "former Olympic swimmer Hiroko Nagasaki commented on a Fuji TV broadcast. A memory that still haunts many in Japan is that of Kokichi Tsuburaya, the marathon, runner who finished third at the 1964 Tokyo Games. Four years later, while in training for the Mexico City Olympics, Tsuburaya killed himself by cutting his wrist in his dormitory. He was found holding his bronze medal. "I remember Tsuburaya’ s comments before he committed suicide," follow marathoner Kenji Kimihara told the Nikkan Sports newspaper this year. "He said ’I committed an inexcusable mistake in front of the Japanese people. I have to beg their pardon by running and hoisting the Hinomaru [national flag] in Mexico." The media are partly responsible for the pressure, but they reflect the general attitudes of the population. And the nation’s fans don’t seem to be having much fun. Last week, hundreds of Japanese endured a horrific schedule to watch their team battle Brazil in soccer. They took a nine hour flight from Osaka to Brisbane, traveled by bus to the stadium, dutifully watched the game and left immediately for the airport for the return trip to Osaka. They were home in time for work the next morning. "They got there and acted like the cheering was compulsory," says Urushibara. "They didn’ t seem to really enjoy the game. It is work. It is what members of the group do." Sadly, even when an athlete lives up to expectations, the demanding drum-beat for victory doesn’t cease. On opening day, Tadahiro Nomura won a gold medal in judo in impressive fashion by "dropping" his opponent in just 14 seconds. It was his second Olympic victory, but Nomura had little chance to savor the moment. "What about 2004" a reporter asked seconds after his victory. No one could blame the quiet champion if he felt like folding up his judo jacket and never putting it back on again. What do the examples in para. 3 ＆ 4 mean

TEXT C The Guildford Four, freed last week after spending 15 years in prison for crimes they did not commit, would almost certainly have been executed for the pub bombing they were convicted of had the death penalty been in force at the time of their trial. There may now be a decent interval before the pro-hanging lobby, which has the support of the Prime Minister, makes another attempt to reintroduce the noose. Reflections along these lines were about the only kind of consolation to be derived from this gross miscarriage of justice which is now to be the subject of a judicial inquiry. In the meantime, defence lawyers are demanding compensation and have in mind about half a million pounds for each of their clients. The first three to be released -- Mr. Gerald Conlon, Mr. Paddy Armstrong and Ms. Carole Richardson -- left prison with the 34 pounds which is given to all departing inmates. The fourth, Mr. Paul Hill, was not released immediately but taken to Belfast, where he lodged an appeal against his conviction for the murder of a former British soldier. Since this conviction, too, was based on the now discredited statements allegedly made to the Survey policy, he was immediately let out on bail. But he left empty-handed. The immediate reaction to the scandal was renewed demand for the reexamination of the case against the Birmingham Six, who are serving life sentences for pub bombings in that city. Thus far the Home secretary, Mr, Douglas Hurd, is insisting that the two cases are not comparable; that what is now known about the Guilford investigation has no relevance to what happened in Birmingham. Mr. Hurd is right to the extent that there was a small-though flimsy and hotly-contested -- amount of forensic evidence in the Birmingham case. The disturbing similarity is that the Birmingham Six, like the Guilford Four, claim that police of- ricers lied and fabricated evidence to secure a conviction. Making scapegoats of a few rogue police officers will not be sufficient to expunge the Guildford miscarriage of justice. These are already demands that the law should be changed first to make it impossible to convict on "confessions" alone; and secondly to require that statements from accused persons should only be taken in the presence of an independent third party to ensure they are not made under coercion. It was also being noted this week that the Guilford Four owe their release more to the persistence of investigative reporters than to the diligence of either the judiciary or the police. Yet investigative reports -- particularly on television -- have recently been a particular target for the condemnation of Mrs. Thatcher and some of her ministers who seem to think that TV should be muzzled in the public interest and left to get on with soap operas and quiz shows. To compensate the miscarriage of justice, the defence lawyers may ______.
To get a chocolate out of a box requires a considerable amount of unpacking: the box has to be taken out of the paper bag in which it arrived, the cellophane wrapper has to be torn off, the lid opened and the paper removed, the chocolate itself then has to be unwrapped from its own piece of paper. But this overuse of wrapping is not confined to luxuries. It is now becoming increasingly difficult to buy anything that is not done up in beautiful wrapping. The package itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much of the refuse put out by the average London household each week. So why is it done Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up scarce energy and resources and messing up the environment. Recycling is already happening with milk bottles which are returned to the dairies, washed out, and refilled. But both glass and paper are being threatened by the growing use of plastic. More dairies are experimenting with plastic bottles. The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to do away with plastic altogether in the shops, a suggestion unacceptable to many manufactures who say there is no alternative to their handy plastic packs. It is evident that more research is needed into the recovery and re-use of various materials and into the cost of collecting and recycling containers as opposed to producing new ones. Unnecessary packaging, intended to be used just once, and make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of doing away with packaging as using it sensibly. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function. According the passage, dairies are ______.
