Reading comprehension.

     Honestly, since my son was born, I have thought a lot about how to raise a child. I once heard a story

that told about when a baby was born. The story said that when a baby was born, a new master was born.

The parents of that baby would become the servants. The question is: Why? Based on my observation, this

phenomenon is true. Most parents who don't pay much attention to their kids have difficulties with their kids'

attitude.

     I'll make a comparison of how two families raise their children. The first one is a family with three children.

Both mother and father never say "No" to their children's demands. As a result, all of their children became

stubborn and won't listen to their parents' words, "We can't."

     The second family educated their children strictly from one year old to high school. The parents never

approved or agreed directly to give their children what they wanted. They always postponed one or two days,

even if they could afford it. Due to the way their parents educated them, these children understood that if they

wanted something, they had to wait or they had to make an effort first. As a result, all the kids from the second

family successfully graduated from university on time.

     In my opinion, if we want to be successful parents and raise our children well, we have to start disciplining

them when they are toddlers but not wait until they become teenagers.

根据世界银行的统计报告，发达国家的最终消费支出占GDP的比例一般在80%左右，发展中国家一般在70%以上。近30年来，由于我国经济增长较快，投资率较高，消费率呈现出稳步下降的趋势，最终消费支出占GDP的比例在55%～65%之间波动。2001年至今，消费率则一直保持在60%以下。国民消费在国民经济中所占比重大大低于国际平均水平。
从这段话中可以推断出，我国的消费政策应凋整为：

A．维持现有的国民消费水平，使国民经济发展保持一定的后劲
B．进一步提高国民消费水平，保持国民经济平稳较快发展
C．继续发扬艰苦奋斗的优良传统，努力促使消费水平稳步下降
D．积极提倡超前消费，力争超越发达国家80%的消费指标
