问题 论述题

由于近几年生猪价格过低,饲料成本上升,部分地区发生疫情等因素的影响,我国生猪生产下降。2011年4月以来,生猪及猪肉供应偏紧,价格出现较大幅度上涨,影响了群众生活,带动了物价上涨。据国家统计局7月9日发布的居民消费指数(CPI),6月CPI同比上涨达6.4%,食品价格上涨14.4%,其中,猪肉价格对CPI的贡献率达21.4%。继蔬菜之后,猪肉又成了领涨居民消费水平的又一“出头鸟”。结合上述材料,回答下列问题:

(1)从经济生活角度分析猪肉价格上涨的原因。(8分)

(2)分析猪肉价格上涨对居民生活可能产生的影响有哪些?(9分)

答案

(1)价值决定价格。(3分)由于猪饲料等价格上涨,饲养成本上升,从而导致猪肉价格上涨。(1分)供求影响价格。(3分)由于前几年生猪价格过低,并且许多地区疫情严重,极大挫伤了农民养猪的积极性,从而使生猪和猪肉供应偏紧,价格上扬。(1分)

(2)由于猪肉价格上涨,人们会减少对猪肉的消费需求;(3分)猪肉属于生活必需品,价格对消费的影响程度比较小;(3分)同时人们会增加一些与猪肉互为替代品商品的消费,如鱼类和其他副食品。(3分

题目分析:本题以猪肉价格上涨这一热点材料为背景考查学生对教材知识的理解和运用能力。回答第(|)问时,影响价格变动的因素主要有两个:可以从一是价值决定价格,二是供求影响价格角度回答,第(2)问价格变动对生活的影响。一般说价格上涨,人们会减少对猪肉的消费需求;价格对生活必需品的影响程度比较小;人们会增加一些与猪肉互为替代品商品的消费。

Children are a relatively modem invention. Until a few hundred years ago they look like adult, wearing grown-up clothes and grown-up expressions, performing grown-up tasks. Children did not exist because the family as we know it had not evolved.
Children today not only exist; they have taken over in no place more than in America, and at no time more than now. It is always Kids Country here. Our civilization is child-centered, child-obsessed. A kid’s body is our physical ideal. In Kids Country we do not permit middle-aged. Thirty is promoted over 50, but 30 knows that soon his time to be overtaken will come.
We are the first society in which parents expect to learn from their children. Such a topsy-turvy situation has come to abort at least in part because, unlike the rest of the world, ours is an immigrant society, and for immigrants the only hope is in the kids. In the Old Country, that is, Europe, hope was in the father, and how much wealth he could accumulate and pass along to his children. In the growth pattern of America and its ever- expanding frontier, the young man was ever advised to GO WEST; the father was ever inheriting from his son. Kids Country may be the inevitable result.
Kids Country is not at all bad. America is the greatest country in the world to grow up in because it is Kids Country. We not only wear kids clothes and eat kids food; we dream kids dreams and make them come tree. It was, after all, a boys’ game to go to the moon.
If in the old days children did not exist, it seems equally true today that adults, as a class, have begun to disappear, condemning all of us to remain boys and girls forever, jogging and doing push-ups against eternity.

The young man was advised to Go West to ______ .

A.find and accumulate more wealth
B.get more free land for the family
C.be the pioneers of the West
D.expand the country’s territory
