举一反三的答案和解析：

[单选题]根据下列文章，回答36～40题。In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw - having extracted them from the mouths of his slaves.That's a far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historians have begun to focus on the roles slavery played in the lives of the founding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings. And only over the past 30 years have scholars examined history from the bottom up. Works of several historians reveal the moral compromises made by the nation's early leaders and the fragile nature of the country's infancy. More significantly, they argue that many of the Founding Fathers knew slavery was wrong - and yet most did little to fight it.

stress the role of slaves in the U.S. history.

解析：根据文章的逻辑一致性和联系，从第二段的“But recently, many historians have begun to focus on the roles of slavery…..”可以看出作者在第一段举George Washing(第一任美国总统)对待奴隶的例子是为了说明“美国历史上奴隶制的作用”。因此选C。

解析：

 该题考查部门劳动生产率与单位商品价值量及使用价值数量的关系。商品的价值量由生产商品的社会必要劳动时间决定的，因此部门劳动生产率提高，生产商品的社会必要劳动时间缩短，单位商品的价值量降低，商品的数量即使用价值增加，商品的价值总量不变。

[考点] 劳力型心绞痛症状学诊断要点
