In 1997, the High Court in London found that environmental campaigners Helen Steel, aged 34, and Dave Morris, 44, were guilty of distributing a pamphlet containing allegations against McDonald’s and their fast food and its preparation. The trial lasted three years and brought to light much evidence about the way McDonald’s hamburger chain workers prepared, handled and served food, and the treatment of these workers by the American-owned company. The High Court in London awarded McDonald’s damages of 60,000 pounds (RMB 780,000) against the two penniless campaigners. But in 1999, three Appeal Court Judges in London decided that the two defendants found guilty of libel against McDonald’s in 1997 would have the damages they have to pay to McDonald’s reduced to 40,000 pounds (RMB 520,000). While upholding the libel ruling, the judges backed the defendants' claim the food carries health risks and said allegations McDonald’s workers suffer poor pay and conditions are "fair comment". The judges also backed a claim by the defendants that eating the company’s hamburgers can cause heart disease. The claim that "if one eats enough McDonald’s food, one’s diet may well become high in fat..., with the very real risk of heart disease, is justified," said Lord Justice Pill, who was sitting in the Court of Appeal with Lord Justice May and Justice Keene. The appeal decision is likely to be a further embarrassment to McDonald’s, whose three-year action against environmental campaigners Helen Steel and Dave Morris generated extensive negative publicity. Peter Backman, chief executive of Food Service Intelligence, a research group, said: " McDonald’s is very conscious of what people say about them. They have got where they have by listening to consumers. I think their strategy will be to downplay the ruling, refute the comments, and thirdly, to do something about it." McDonald’s said it welcomed the Court of Appeal decision to uphold the 1997 libel ruling. The company faces another $200,000 legal bill for the 23-day appeal hearing. Steel and Morris were to take the case to the House of Lords and the European Court of Human Rights to appeal against the damages awarded against them. They present much of their cases themselves and any lawyer’s fees are largely paid for by donations. The pair have yet to win court backing for claims that McDonald’s damages the environment, or that there are links between its hamburgers, cancer and food poisoning. The fast-food chain has not yet recovered a penny of its original libel award from the defendants, who are refusing to hand over any money. One benefit of the long trial was that A．McDonald’s become more famous after that. B．people knew a lot about the food processing in McDonald’s. C．the way McDonald’s treated its workers has been improved. D．the government got a sum of money from it.

Currently there are some 20,000 chemicals in use, but the scientists only have detailed information around 1,000 of them.To see the advantages of GM food you have only to consider the recent press revelation that the average lettuce receives eleven pesticide applications before it reaches the supermarket shelf.I’m sure chemicals and their role in disease will become a big issue in the 21st century as the population of the developed world worries increasingly about its health. The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world’s predicted population growth to ten or eleven billion.It’s not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture. The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we’re on the edge of a new one: a genetic revolution. It may well be that in the long term it is the developing world that benefits most from GM food.It is true that for the next years or so GM crops may be too expensive. 6. According to the passage, food supplies have been increased by all the following except_____________. A.pesticides B.artificial fertilizers C.improved varieties D.transportation 7.How many chemicals are still less familiar to the scientists？() A.20,000. B.1,000 C.19,000 D.21,000. 8.Why will people prefer GM food in the future？() A.Because it uses less pesticides. B.Because it is much cheaper. C.Because the production is increased. D.Because it is organic food. 9.Which of the following is NOT true？() A.By 2050, the world population will grow to ten or eleven billion. B.In the 21st century, GM food will take the place of conventional food. C.More and more people will reduce the overall land available for farming. D.More and more people will consume more food and occupy more space. 10.The author’s attitude towards GM food is _______. A.negative B.positive C.critical D.uncertain
