Australian sleep researchers have developed a set of hi-tech "sunglasses", described as the world's first "time control" glasses, which can imitate sunlight patterns. The team, from Flinders University, in Adelaide, says the glasses send out a soft green glow that helps a traveller adapt to changing sleep patterns and time zones in "small steps". It targets a part of the brain that regulates the human body-clock, by sending signals to the rest of the body that help it slowly realise it is in a different area of the world. It has been suggested the device, called the "Re-Timer", is currently the only wearable body clock adjustment system commercially available. Scientists say the device, officially launched in South Australia, can help ridf the negative effects of long-timel travel and bring new relief to insomnia sufferers, shift workers and even teenagers. "The light from Re-Timer stimulates the part of the brain responsible for regulating the 24-hour body clock," said Prof Leon Lack, its chief inventor. Extensive research has shown that green light is one of the most effective wavelengths for influencing the body clock. The battery-powered device, which retail for PS162 in Britain, then sends signals that cause the production of hormones and daily cycles known as circadian rhythms . Those people who want to sleep peacefully, but wake earlier, should wear it for 50 minutes in the morning for three days. Those who want a lie- in, should wear it for the same time before bed to delay the body clock. The device, which is powered by an inbuilt rechargeable battery, can also be worn as sunglasses during daily tasks such as reading or using a computer. "The glasses have been designed to be user friendly and comfortable to wear so people can go about their normal activities wearing them at work or at home," he said, adding they had been designed based on 25 years of university research. It is estimated that up to 94 per cent of long-time travellers suffer from jet lag because the body becomes confused to... What can we learn about the "Re-Timer" from the passage? A) It is a new way to cure insomnia B) It can only be powered by battery C) It can be used by several groups of people D) It is specially designed for flight passengers.

China Daily: As China comes down from a travel rush during the seven-day holiday for National Day, people called for a return of the Labor Day Golden Week holiday as a way to ease the travel peak. By Friday, 79 million passengers were expected to have used the railways up about 8 percent over last year. Waterways had shipped around 2 million, a rise of about 17 percent on last year, www. cntv. cn, the website of China Central Television, said on Saturday. As large numbers of tourists _ scenic spots around China, it caused huge crowds and many complaints. The Forbidden City in Beijing has long been a big draw for travelers. On Tuesday alone, the museum reported, it received more than 180,000 visitors, about six times higher than a regular day. According to China Central Television, restless visitors demanded their money back from the tourism committee, and police were sent to help deal with the problem. The Beijing-HongKong-Macao expressway, the Shanghai-Kunming expressway and the route from Beijing to Kunming saw large increases in traffic on Saturday, according to www. cntv. cn. "As there are only two long holidays in the country and paid leave is not well carried out by employers , people have limited chances for travel", Dai Bin, the director of China Tourism Academy, said in a report by Beijing Times on Saturday. "The travel rush during the 'Golden Week' holidays happens because people do not take long journeys during shorter holidays", said Liu Simin, a researcher with the China Academy of Social Sciences, in a report by Beijing Times on Saturday. Liu said that now the most important task is to ease the pressure from the huge numbers of tourists. When the Labor Day Golden Week holiday came to an end in 2007, a chance to travel was reduced. In 2008, the government shortened the Labor Day Golden Week holiday, usually lasting from May 1 to May 7, to three days and added three other short vacations to the list. What is the passage mainly about? A) Seven-day Golden Week Holiday sees huge crowds on popular tourists spots B) The problem during the seven-day Golden Week Holiday. C) Travel complaints. D) The pressure from the huge numbers of tourists.

Q: Whatever our differences as human beings are we all think we're more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic structure with the simple worm. But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome . To help them do this, they turned to the worm. The nematode worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better. What the worm told Sir John and his colleagues was that each of the cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up. Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death. Sir John Sulston got a Nobel Prize for Medicine because he has_. A) found that human beings are similar to the worm B) got the fact we share 40 per cent of our genetic structure with the simple worm C) found the computer which controls each of the cells in the human body D) proved that cell death is programmed
