startover(startover这首音乐表达什么)

At the start of the 20th century, an American engineer named John Elfreth Watkins made predictions about life today.

在20世纪初，一位名叫约翰·埃尔弗里斯·沃特金斯的美国工程师，对今天的生活做出了预测。

His predictions about slowing population growth, mobile phones and increasing height were close to the mark.

他对人口增长放缓、移动电话和身高增长的预测接近事实。

But he was wrong in one prediction: that everybody would walk 10 miles a day.

但他有一个预测错了:每个人每天都会走10英里。

Today, in Australia, most children on average fall 2, 000 steps short of the physical activity they need to avoid being overweight.

今天，在澳大利亚，大多数儿童平均要跌到2000步才能达到避免超重所需的运动量。

In the early 1970s, 40 per cent of children walked to school, while in 2010, it was as low as 15 per cent.

在上世纪70年代初，40%的儿童步行上学，而在2010年，这一比例低至15%。

The decline is not because we have all become lazy.

这种衰退并不是因为我们都变得懒惰了。

Families are pressed for time, many with both parents working to pay for their house, often working hours not of their choosing, living in car-dependent neighborhoods with limited public transport.

家庭的时间都很紧张，许多家庭的父母都要工作来支付他们的房子，工作时间往往不是他们自己选择的，生活在依赖汽车的社区，公共交通有限。

The other side of the coin is equally a deprivation: for health and well-being, as well as lost opportunities(机会)for children to get to know their local surroundings.

硬币的另一面是同样一个不足:对于健康和幸福,以及失去了对孩子了解当地的环境的机会。

And for parents there are lost opportunities to walk and talk with their young scholar about their day.

对于父母来说，他们失去了与年轻学者散步和交谈的机会。

Most parents will have eagerly asked their child about their day, only to meet with a “good”, quickly followed by "I'm hungry".

大多数父母都会急切地问他们的孩子一天过得怎么样，只会得到一个“很好”，紧接着是“我饿了”。

This is also my experience as a mother.

这也是我作为一个母亲的经历。

But somewhere over the daily walk more about my son's day comes out.

但在每天的散步中，我发现了更多关于我儿子一天的事情。

I hear him making sense of friendship and its limits.

我听到他对友谊及其界限的理解。

This is the unexpected and rare parental opportunity to hear more.

这是家长们意想不到的难得去了解孩子的机会。

Many primary schools support walking school-bus routes(路线), with days of regular, parent-accompanied walks.

许多小学支持走校车路线去上学,在大多数的日子里，有大人陪同走。

Doing just one of these a few times a week is better than nothing.

每周只做几次，总比什么都不做要好。

It can be tough to begin and takes a little planning-running shoes by the front door, lunches made the night before, umbrellas on rainy days and hats on hot ones-but it's certainly worth trying.

这可能很难开始，需要一点计划——门前的跑鞋，前一天晚上做好的午餐，下雨天的雨伞，天气炎热的时候戴上帽子——但这确实值得一试。
