政治经济学之所以要研究使用价值的原因在于 ( )
A．使用价值本身就是政治经济学的对象
B．商品的使用价值是商品最本质的属性
C．使用价值决定着价值和交换价值
D．使用价值是价值和交换价值的物质承担者
参考答案：D
解析：[注释] 商品的使用价值是指商品能够满足人们的某种需要的属性。使用价值是由商品的自然属性决定的，不同种类的商品具有不同的自然属性，因而具有不同的使用价值。使用价值的生产和再生产是人类社会生存和发展的物质前提，但使用价值本身并不反映任何社会生产关系，它与财富的社会形式无关。政治经济学之所以要考察使用价值，是因为使用价值是商品价值的物质承担者。因此，正确选项为D。

| These days, cars are designed using computers. Let's look at how a new car is created. First, several 1 talk about the new car and any good ideas that they have. Then they sit down at their computers and 2 many sketches. The best two or three drawings are chosen and then more detailed drawings of 3 are developed on the computer. You can change the size, shape or color of any part on the computer to see 4 the car would look and then you can choose the best design. Both the inside and the outside of the car have to be designed. Part of the inside of the car is 5 so that the designers can sit in it. They can feel if there is enough 6 inside and if they can reach 7 . Then some cars are built-there are more than 15, 000 parts of a car to 8 . When everything is known to be 9 . the cars are made in the factory. Again, computers are used to make sure that all the parts are 10 as they are needed. The factory usually stays open all through the night so that the car production never stops. | ||||
