猪肉价格周期性波动需要不同手段共同作用。生猪价格指数保险也不能完全解决猪肉价格周期性波动问题。但它至少有助于打破“价格过低——养殖户亏损——退出养殖——未来供应最减少——价格高涨——需求量下降——产品积压——价格下降”这个怪圈。若 P 是需求曲线, S 是供给曲线,其他条件不变,生猪投保后会带来一些变化,正确反映这一变化的曲线图是

答案

答案:B

题目分析:实行生猪价格指数保险后,用于稳定生猪的供给,从而达到稳定价格折目的,故变动的是供给曲线,所以排除CD选项,实行生猪价格指数保险后,价格的变动给养猪业带来的影响小了,从而市场供给不会大幅度减少,故B正确。答案选B。

     I can’t remember a winter being as cold as this in Pennsylvania, but I’m sure there were colder days.

     Even though the daylight hours are growing longer minute by minute, it’s easy to find an excuse not to go out unless you absolutely must, but then again I often have to push myself to accomplish things.

     People I speak to have been in all kinds of nasty moods. They say they’re “under the weather,” not feeling good about this time of year.

     As I stood outside with my two dogs yesterday, it was so cold that my nose and face felt frozen and my ears were stinging.

     Of course, that doesn’t matter to Ricky and Lucy. They have a routine they must go through to find just the fighting spot no matter how cold or hot it is.

     So I wait.

     But this time it was different. As cold as it was, I suddenly was excited thinking about how wonderful this extreme cold really was.

     Then the sun broke through the clouds and memories of summer’s extremely hot days flashed through my mind. I could remember standing in the heat of the afternoon, with sweat pouring down my brow and the hot, burning sun against my face. I reminded myself then and there that in the cold of the winter I would wish I had this heat.

     I was grateful for the extremes. Without the extremes in my life, I would never appreciate the days when things were just right. Without the extremes, life would be boring.

     It’s being pushed to one of the extremes that makes us appreciate the middle more. Health challenges remind us that we need to pay more attention to how we live. Financial extremes remind us that when things go smoothly it’s also time to save for raining days.

     I’ve come to the conclusion that all too often I find a reason not to be happy with where I am at that moment.

     Whether it’s hot or cold, good health or bad, in the money or out of it, I always want it to be different.

     I’m tired of being “Under the Weather!”
