劳动生产率与商品的使用价值量成正比 劳动生产率与单位商品的价值量成反比 同一社会必要劳动在同样时间内创造的价值量与劳动生产率的变化无关

题目：商品的使用价值量、价值量与劳动生产率的关系是（ ）

解析：

【参考解析】： 劳动生产率通常用单位时间内生产的商品数量或单位商品生产所需的劳动时间来表示。单位时间内生产的商品数量越多，劳动生产率就越高，劳动生产率与商品使用价值量成正比。劳动生产率是指具体劳动的生产率。因此，无论劳动生产率如何发生变化，同一劳动在同一劳动时间内所形成的价值量是不变的，而由于劳动生产率的提高，会使单位时间内生产的商品数量增加，从而单位商品的价值量变小，即劳动生产率与单位商品的价值量成反比。

[单选题]Passage 5 When I decided to quit my full time employment it never occurred to me that I might become a part of a new international trend. A lateral move that hurt my pride and blocked my professional progress prompted me to abandon my relatively high profile career although, in the manner of a disgraced government minister, I covered my exit by claiming “I wanted to spend more time with my family".

Curiously, some twoandahalf years and two novels later, my experiment in what the Americans term “downshifting" has turned my tired excuse into an absolute reality. I have been transformed from a passionate advocate of the philosophy of “have it all", preached by Linda Kelsey for the past seven years in the pages of She magazine, into a woman who is happy to settle for a bit of everything. I have discovered, as perhaps Kelsey will after her muchpublicized resignation from the editorship of She after a buildup of stress, that abandoning the doctrine of “juggling your life", and making the alternative move into “downshifting” brings with it far greater rewards than financial success and social status. Nothing could persuade me to return to the kind of life Kelsey used to advocate and I once enjoyed: 12-hour working days, pressured deadlines, the fearful strain of office politics and the limitations of being a parent on “quality time”. In America, the move away from juggling to a simpler, less materialistic lifestyle. is a-well-established trend. Downshifting — also known in America as “voluntary simplicity” — has, ironically, even bred a new area of what might betermed anti-consumerism. There are a number of bestselling downshifting self help books for people who want to simplify their lives; there are newsletters, such as The Tightwad Gazette, that give hundreds of thousands of Americans usefultips on anything from recycling their clingfilm to making their own soap; there are even support groups for those who want to achieve the mid'90s equivalent of dropping out. For the women of my generation who were urged to keep juggling through the '80s, downshifting in the mid'90s is not so much a search for the mythical good life — growing your own organic vegetables, and risking turning into one — as a personal recognition of your limitations. 第67题：Which of the following is true according to paragraph 1?

The writer was compelled by circumstances to leave her job.

解析：选［B］。本题一道推理性题目，需要正确理解文章第一段才能做出正确选择，本段第一指出是作者辞去全职工作时才发现自己加入了一个国际大潮中，显然全职工作不是这个国际大潮。第二句中的a lateral move的意思是"平行移动，横向移动"，显然不是指不做全职工作。而正是这个伤害作者自尊心、阻碍她职业发展的"平行移动"促使她放弃了她较高形象的职业生涯。本段最后一句指出作者声称："I wanted to spend more time with my family"只是用来"cover"她的职职的。可见，作者是由于环境因素才辞去工作的，［B］为正确选项。
