(12分)2010年大蒜、绿豆、叶菜、玉米等农产品价格大幅上涨。“蒜你狠”、“豆你玩”、“辣翻天”等网络热词诞生,是对“疯狂的菜价”进行的调侃。

镜头一:2010年10月韩国泡菜危机波及中国,造成大白菜价格持续攀升。面对菜价的攀升,部分市民表示:“白菜价格高就少吃点,还有生菜,萝卜和豆芽等蔬菜可以购买。”

镜头二:韩国白菜危机持续时间不长。2010年11月白菜价格已经开始下跌。山东某市场一位菜农在接受媒体采访时说:“昨天这时候还8角钱一斤,今天就变成6角钱。之前大家都觉得这是个商机,不想只卖了两天就卖不出去了。”部分菜农因为囤积了大量白菜而亏损严重。

(1)白菜价格的攀升对人们生活产生什么影响?(6分)

(2)假如你是其中一户菜农,你认为有哪几种摆脱困境的方案可供选择?请运用“价格对生产的影响”相关知识加以说明。(6分)

答案

(1)①一般说来,当某种商品价格上升时,人们会减少对它的购买;反之,增加对它的购买。面对高价白菜,人们会减少对白菜的需求量。(3分)

②消费者的需求还受相关商品的影响。白菜价格高了,人们需求减少,转而消费替代品,因此白菜的替代品的需求量增多。(3分)

(2)要摆脱困境,有以下几种方案可选择:

①调节生产规模。适时减少白菜的生产规模或者调整产品品种。(2分)

②改进技术和改善经营管理,以提高个别劳动生产率,降低种植白菜的成本。(2分)③生产适销对路的高质量产品。可以引进新技术,把拆散深加工,提高其附加值。(2分)

     The World Health Organization says obesity rates are rising in Pacific island countries. So, too, are

health problems linked to being overweight.

     The WHO says a major reason for the rising obesity rates is an increase in imported foods. It says

many Pacific islanders have replaced their traditional diets of vegetables and fruits with imported

processed foods.

     Dr. Temu Waqanivalu is with the World Health Organization's South Pacific office in Suva, Fiji. He

says many of the imported products lack nutritional value.

      Temu Waqanivalu said: "In some of the places, you'd be amazed to see how a bottle of Coke is

cheaper than a bottle of water. I think that represents the kind of offenvironment we've created that

doesn't really encourage or make lifestyle choices an easy choice for the population."

     And a lack of physical activity among many Pacific islanders only adds to the obesity problem.

     The WHO says more than 50 percent of the population is overweight in at least ten Pacific island

countries. The rate is as high as 80 percent among women in the territory of American Samoa.Fiji had

the lowest obesity rate at 30 percent.

     In all, almost ten million people live in Pacific island countries. The WHO estimates that about 40

percent of them have health disorders related to diet and nutrition.

     Diabetes rates are among the highest in the world. Fortyseven percent of the people in American

Samoa have diabetes. So do 44 percent of the people in Tokelau, a territory of New Zealand.

     By comparison, the diabetes rate is 13 percent in the United States, a country that has its own

problems with rising obesity.

      Officials also note an increase in nutritional problems like anemia and not enough vitamin A in the

diets of Pacific islanders. Dr.Waqanivalu says treating conditions related to obesity and diet puts

pressure on limited health resources and budgets.
