Once in a television interview, I was chatting with the host about stay – at – home athers. I made the point that one reason why we’re seeing more stay – at – homw dads may be hat it’s no longer definite that a man makes more money than his wife. Many families now ake earning power into account when deciding which parent will stay home.

At that point, one of the male crew members pointed out, almost to himself but loud nough for my benefit, “It should be the better parent who stays home.” A lot of guys say hings like that. Usually it’s a code for “My wife, or any woman is the better parent.”

I was a stay – at – home father for 8 years, so his words made me excited. It implied that our family’s choice could only have been correct if I was a “better” parent than my wife.

I suppose an argument could have been made that when I began staying home my wife was the “better” parent if she spent more time with Jack. She would be able to read him wetter and calm him more quickly. But as the more employable one, my wife went out to work and I looked after our son.

because of the increased time I spent with Jack. I soon knew him well, understood that he needed and could look after him more or less as well as my wife could. Actually, he experience helped me unlock one of the world’s great secrets; Women are good at booking after children because they do it. It is not because of any innate (先天的) female talent. It is because they put in the time and attention required to become good at the job.

Woman obviously get a biological head starting from giving birth and nursing, but ever the long term experience is more important. When I got the experience myself. I was people are able to look after them as well besides their moms.

国务院发布的《节能与新能源汽车产业发展规划（2012—2020年）》显示：越来越多的人开始关注新能源汽车。材料一：拥有节能、环保等好处的新能源汽车，为什么仍飞不到寻常百姓家呢？半数人认为新能源汽车价格偏高：一方面，关键技术尚未突破，企业研发投入大，产品成本高，特别是动力电池价格高昂，成本要占整车造价的二分之一；另一方面，虽然国内企业对发展新能源汽车的热情高涨，但更多的还是在造势，现实产量和保有量并不高，可选车型不多。材料二：新能源汽车的发展，绝不能绕过普通消费者这个庞大的消费群体，我国将加大从消费方面推动新能源汽车发展，倡导“绿车”消费，激励购买新能源汽车，积极培育新的消费热点带动新能源汽车产业的发展，发挥消费对产业发展和经济增长的重要带动作用，相信新能源汽车的春天将不会太远。

结合材料二，运用消费对生产的反作用知识，说明倡导“绿车”消费对汽车产业的影响。
