下文通过一位美国工程师的预言，引出21世纪青少年缺乏运动，过度肥胖的社会问题…… (2021·1月浙江阅读精编)At the start of the 20th century, an American engineer named John Elfreth Watkins made predictions(预测；预言) about life today.His predictions about slowing population growth, mobile phones and increasing height were close to the mark1.But he was wrong in one prediction: that everybody would walk 10 miles a day. Today, in Australia, most children on average2 fall 2,000 steps short of3 the physical activity they need to avoid being overweight.In the early 1970s, 40 per cent of children walked to school, ①while in 2010, it was as low as 15 per cent. The decline(减少；下降) is not because we have all become lazy.Families are pressed for time4, many with both parents working to pay for their house, often working hours not of their choosing, living in car­dependent neighborhoods with limited public transport. ❶The other side of the coin5 is equally a deprivation: for health and well­being, as well as lost opportunities(机会) for children to get to know their local surroundings.And for parents there are lost opportunities ②to walk and talk with their young scholar about their day. Most parents will have eagerly asked their child about their day, only to meet with a “good”， quickly followed by “I'm hungry”．This is also my experience as a mother.But somewhere over the daily walk more about my son's day comes out.I hear him making sense of6 friendship and its limits.This is the unexpected and rare parental opportunity to hear more. Many primary schools support walking school­bus routes(路线), with days of regular, parent­accompanied walks.Doing just one of these a few times a week is better than nothing.❷It can be tough to begin, but it's certainly worth trying. 【词块采撷】 1．close to the mark　　　　　 接近目标 2．on average 平均而言 3．fall sth short of 缺乏，不足 4．be pressed for time 时间紧 5．the other side of the coin 事情的另一面 6．make sense of 理解；弄清楚 【亮句应用】 ①while作表示对比意义的并列连词 (2021·天津)By the time we got to middle school it was clear that my older
