雅思阅读真题原文如下：

A. Recent research in Hong Kong indicates that staying in bed after a long week at school is just what children need to avoid becoming obese, The research, which focused on children aged five to fifteen, discovered that those who slept late on Saturdays and Sundays decreased the probability of having weight problems as they grew up. Published in the journal Paediatrics, the findings add to previous research that indicated a connection between regular sleep deprivation and obesity.

B. The scientists involved believe the weekend lie-in is vital for school-age children to catch up on the sleep they lose during a busy week at school. This catch up sleep helps the children to regulate calorie consumption by cutting down on eating snacks during waking hours, Scientists and others in the medical fields have long known that a lack of sleep and irregular sleep patterns causes obesity as this combination affects the body’s natural metabolism and tends to also encourage snacking to reduce the feeling of tiredness. However, this is thought to be the first time researchers have found sleeping in at weekends to be a key factor in helping ‘reset’ children’s sleeping patterns.

C. Since the 1980s, obesity rates among children in the UK and in the United States have been on the rise and medical and childcare experts fear a diabetes and heart disease epidemic is developing. Although estimates for obesity rates have recently been lowered, current expectations are that close to one in three boys aged from two to eleven are likely to be overweight or obese by the year 2020. The prediction for girls is slightly over one in four, a much lower prediction than ten years ago when forecasts were that almost half would be overweight.

D. The relationship between sleep deficiency and obesity has been drawing much attention in the past several years with studies showing that sleeping just a few hours a night can seriously disturb the body’s natural metabolism, leading to an increase in overall calorie intake and a much greater danger of weight-related illnesses. Yun Kwok Wing of Hong Kong University and other experts investigated the possibility that catching up on sleep at the weekends would help youngsters to overcome such disruption of the bodies metabolism. They questioned the parents of over 5,000 schoolchildren and accumulated data on diet, lifestyle, weight and sleeping habits. During school time, the average amount of sleep was a little over nine hours on average. However, a surprising number of kids slept well under eight hours a night.
