Chinese students aren't the only ones who have a sleep loss problem. In Australia, teenagers are also missing out on, on average, one hour's sleep every night during the school week. Organized activities and homework push bedtimes later, the first large-scale Australian study of children's sleeping habits has revealed . Their sleep deprivation is enough to cause "serious drop-offs in school performance, attention and memory", and governments should consider later or flexible school start times, said the study's leader, Tim Olds. ks5u His survey, of more than 4,000 children aged 9 to 18, found those who slept least did not watch more television but spent their time socializing with family or friends or listening to music. "Almost all children get up at 7 or 7:15 -- they have to get to school on time," said Olds. He favors a later start over an earlier finish because he believes organized sports and activities would still consume the latter end of the day. Olds' research also establishes lack of sleep as a cause of weight gain in children, and a possible source of future problems with depression, anxiety and increased susceptibility to illness. It was already known that overweight children sleep less, but Professor Olds found sleep duration was strongly linked to weight across the full range of body sizes. The thinnest children sleep 20 minutes more than the _ . This showed being overweight had no specific effect on sleep patterns, and it was more likely that shorter sleep times stimulate appetite and make kids hungry. The US National Sleep Foundation says teenagers aged 13 to 18 need eight to nine hours' sleep a night. Younger school-aged kids need 9 to 11 hours. On that basis, Professor Olds said, half of Australian children are under-sleeping on weekdays and a quarter on weekends. Which of the following statements is TRUE? A) Australian students usually take part in activities in the afternoon. B) More students are short of sleep on weekends than on weekdays. C) Being overweight has an effect on the length of the sleeping time. D) The survey suggests that teenagers need 8-9 hours' sleep a night.

Ques: Asia-Pacific consumers are the world's largest group of online shopping lovers and many rely on Internet reviews when making purchases, research firm Nielsen said this week. The firm said 35% of consumers in Asia-Pacific used over 11% of their monthly spending to make online purchases, compared to a global average of 27% of consumers. South Koreans were the heaviest online buyers in Asia, with 59% directing more than 11% of their monthly spending to online purchases, followed by 41% in China, Nielsen said in a report. A further 31% of Asian consumers use between 6% and 10% of their monthly shopping purchases to buy items online. More Asia-pacific consumers also intend to buy online in the next six months than those from other regions, with South Koreans and Chinese the most likely to make such purchases. Among the purchases consumers in the region are likely to make in the next six months are books, clothing, shoes, airline tickets, electronic equipment and hotel reservations. "Technology and the Internet will very likely basically change how and where shoppers spend their money and interact with sellers," said Pete Gale, a managing director at Nielsen's Retailer Services. "We are seeing a strong trend in markets like Korea, where a significant population of online shoppers buy essentials such as groceries, cosmetics and nutrition supplies over the Internet." Nielsen said opinions posted online were important in Asia-pacific customers' decisions to buy products such as cosmetics, cars, software and food. Asia-pacific consumers were also the most likely to share dissatisfaction at a product on the Internet compared with consumers elsewhere. "The increasing accessibility of the Internet and unbelievable popularity of social media and online discussion forums mean today's brands have nowhere to hide, " said Megan Clarken, Asia-Pacific managing director at Nielsen's online division.
