Article: A British company has proposed releasing genetically modified(GM) diamondback moths, which would reduce the population of the vegetable-eating insects. Males carrying a deadly gene would be released, which would cause their young ones to die immediately. Then the fall in their numbers could help increase production for farmers. Oxitec, the company which came up with the idea, hopes to begin trials next year, but some groups are saying no to them,, saying the untested technology could threaten wildlife and human health. "Mass releases of GM insects into the British countryside would be impossible to recall if anything went wrong. Changing one part of an ecosystem can have knock-on-effects on others in ways that are poorly understood. This could include an increase in different types of pests. Wildlife that feeds on insects could be impaired if there are changes to their food supply," said Dr Helen Wallace, the director of Gene-Watch UK. Hadyn Parry, Oxitec's chief executive, said that there was demand from farmers for the technology and that using GM insects to kill the pests that feed on food crops is better for the environment than chemical sprays. The firm is developing a number of GM insects that would be used in Britain and around the world to protect crops and fight disease in humans. Oxitec has contacted the Health and Safety Executive (HSE) to ask what controls should be put in place around GM moth trials. A spokesman said that while its officials and advisers have discussed Oxitec's plans, there has not been a formal application for a trial. As a result, the department has not reached a view on whether it should go ahead. Question: What is the purpose of releasing GM insects into the British countryside? Options: A: To kill pests feeding on crops. B: To help some natural insects survive. C: To prevent the use of chemical sprays. D: To prove that GM technology is helpful.

Some people say that if you have never walked through a Chinese garden, you cannot say that you have really visited China. Traditional Chinese gardens are located in North China in such places as Beihai Park, the Summer Palace, the Forbidden City. In larger imperial gardens, the main buildings are connected by an imaginary line in the middle of the garden on the north-south axis . Other features of imperial gardens are colored-paintings, man-made hills and lakes. Most private gardens are found in the south, especially in cities south of the Yangtze River. Private gardens were mostly built at one side or at the back of the houses. Around the beautiful scene are small open areas with beautiful shaped-doors through which visitors can enjoy the sights. _ are open on all sides and are often near the water so that the whole scene can be enjoyed. Suzhou, known as the home of gardens, displays the most and the best Chinese traditional private gardens.

Q: Read the article and select the best answer. Article: Zipped into a bag, it looks like a large umbrella. Unfolded, it goes along the street like any other bicycle. It's the "A-bike", the brainchild of British inventor Sir Clive Sinclair, who made history in the 1970s by developing the world's first pocket calculator. He described his new invention as "the world's smallest, lightest foldable bicycle". "My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used,"said Sinclair. The mini-bike, showed in Singapore last week and set to go on sale worldwide in 2005 at a price of nearly US$300, is built for riders as heavy as 112 kilograms and is height-adjustable . It takes about 20 seconds to fold or unfold. Its wheels are a quarter the size of those on a regular bicycle, but Sinclair promises a smooth ride for most cyclists. "You require no extra energy to ride the A-bike and it can go up to 15 miles per hour (24 kilometers per hour)," he said. Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters . Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the A-bike was to add an electric motor in a few years.
