听力原文: Recovery from jetlag can take as long as a day for every time zone crossed. So if youre flying east-west for your holiday or on business, it is likely to mean a few days of feeling tired or even unwell. Jetlag is the disruption of the bodys natural cycle and some factors make it worse. The artificial atmosphere inside a plane can affect the body in a number of ways and add to the effects of jetlag. Exercising before flights helps to offset the effects on the body of reduced air pressure and aerobic exercise afterwards helps to re-oxygenate it. Drink plenty of water. Children may need more. Drinking carrot juice before flying overcomes oxygen deficiency. Eat light, frequent meals. Heavy meals slow down the blood circulation, which can lead to dizziness and fainting. For two weeks before you fly, eat plenty of food containing vitamins A and E: they will build up your immune system and help to keep you fit. Sleep as much as you can before the flight and on it. On board, wear earplugs and eye pads because darkness stimulates secretion of the hormones that enhance sleep. Avoid alcohol, which restricts the brains oxygen intake. Like tea and coffee, alcohol increases the dehydration effect of flying. If you need to drink to relax, bear in mind that the cabin environment intensifies the effect of alcohol. Wear loose, comfortable, warm clothes and limber up during flight. Sitting down for several hours slows down the circulation, leading to local stiffness, cramps and dizziness. Re-adjust to local time as soon as you can. Bright light helps the body stay alert, so if you are going somewhere sunny, stay outside. Do not smoke before or during the flight since smoking decreases the blood oxygen level. If you need to calm your nerves, try aromatherapy oils which have a sedative effect. Consult your doctor before flying if you are on medication. The effects of some drugs are strengthened at high altitudes and some may produce side effects.

听力原文: Millions of television sets and old computer monitors taken to civic amenity sites as rubbish are being collected and shipped to Africa and Asia, an illegal trade worth 7,000,000 a year, according to an unpublished report by the Environment Agency and the recycling industry. The business carried out by totterspeople who sift through rubbish for saleable objectsbecame illegal on the 1 st of January 2002 under European Union legislation designed to prevent toxic waste material being shipped to developing countries. Electrical equipment containing leaded glass, particularly computers and televisions, were reclassified as toxic waste. The agency is alarmed that half a million televisions and a similar number of computer monitors which people thought were being disposed of in England are being reused or dumped in the developing world. The agency is finding the trade hard to control but is planning to publish guidance to the industry soon. Environment groups point out that this action will not be sufficient to stop an illegal business. Claire Wilton of Friends of the Earth said, The agency has known about this situation for two years but has still failed to act. The companies involved in this illegal trade must be prevented from dumping Britains toxic waste on developing countries, where workers conditions rarely match those expected in Europe. Action must be taken now to stop this environmental injustice continuing. The Industry Council for Electronic Equipment Recycling estimates that 11 ,000 tons of old TV sets, about 500,000 in total, and a similar number of old computer monitors find their way to developing countries each year. Many are cannibalized for spare parts but some are repaired and sold to people who would not otherwise have a television or computer. The Industry Council for Electronic Equipment Recycling defends its members who buy computers and other office equipment from industry and ship them abroad, because under EU rules the business is legal if they are working models and intended to be sold on the second-hand market. The problem arises when equipment is thrown away. The law says if it is discarded, even if it may be working, it must be classed as rubbish and cannot be resold to a developing country because it is technically toxic waste.
