不一样的面谈 小王自己不懂车，他感觉到车的发动机在怠速时，会“当当当”响，觉得声音很烦人，就把车开到了修理厂。一个小伙子接待了他，问车怎么了。小王就说发动机有问题了，当当当响。小伙子接着又问，哪儿响?小王就说不清楚具体是哪儿响，反正就这一块。又问是吗，什么时候开始的?小王说大概有一星期了。 小伙子在车上东看看西看看，也找不到问题究竟出在那里。过一会儿小伙子把他师傅找过来了，他师傅过来以后，提问的方式就马上转变了，第一个问题是发动机的机油换没换，小王说好像是一个月之前换的。接着师傅又问，你这两天车是不是经常点着了却不走，小王回答说是有这种情况。然后师傅又问化油器清洗过吗，小王说前段时间洗的。这时师傅说可能毛病出在化油器上。一看果然如此，化油器堵住了。

Getting a good night's sleep tonight could guard children against weight gain in the future. According to a new study, putting preschoolers in bed by 8p.m. could reduce their chances of becoming overweight or obese (肥胖的) later in life by half. Preschoolers are children around the age of 4 or 5. The term "obese" refers to calculations of your Body Mass Index, what doctors call BMI. They use a person's height, weight and age to assess their amount of body fat. BMIs help tell whether a person is underweight, normal, overweight or obese. The World Health Organization says obesity can lead to serious long-term health problems like diabetes (糖尿病), heart disease and stroke. Researchers from the Ohio State University's College of Public Health have found that young children who go to bed after 9p.m. are twice as likely to be obese later in life. The lead author of the study is Sarah Anderson. She is an associate professor of epidemiology (流行病学). She studies how diseases spread and how they can be controlled. Anderson says that, for parents, the results of the study support the importance of creating a bedtime routine. She says that having a usual bedtime routine is something "families can do to lower their child's risk" of becoming overweight. A usual, early bedtime, Anderson adds," is also likely to have positive benefits on behavior and on social, emotional and cognitive development". Researchers used data from 977 children for the study. These children are part of a larger project called the Study of Early Child Care and Youth Development. The project follows healthy babies born in 1991 in 10 U.S. cities. The children were 4.5 years old when their mothers reported their usual weekday bedtime. Researchers then divided the children into three groups: A)those who went to bed by 8p.m. or earlier; B)those who went to bed between 8p.m. and 9p.m. and C)those whose bedtimes were after 9p.m. When these children turned 15 years old, the researchers looked at their rates of obesity. Of those with the earliest bedtimes, only one out of 10 was obese. Of those who went to bed between 8 and 9p.m., 16 percent became obese. And out of those with the latest bedtimes, 23 percent became obese. Anderson said putting children in bed early does not mean they will immediately fall asleep. But, she adds, it makes it "more likely that children will get the amount of sleep they need to be at their best". What does the first paragraph tell us? ______
