问题     The agricultural revolution in the nineteenth century involved two things: the invention of labor-saving machinery and the development of scientific agriculture. Labor-saving machinery naturally appeared first where labor was scarce. "In Europe," said Thomas Jefferson, "the object is to make the most of their land, labor being abundant; here it is to make the most of our labor, land being abundant. " It was in America, therefore, that the great advances in nineteenth century agricultural machinery first came.
    At the opening of the century, with the exception of a crude plow, farmers could have carried practically all of the existing agricultural implements on their backs; by 1860, most of the machinery in use today had been designed in an early form. The most important of the early inventions was the iron plow. As early as 1790 Charles Newbold of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in introducing his invention. The farmers, however, would have none of it, claiming that the iron poisoned the soil and made the weeds grow. Nevertheless, many people devoted their attention to the plow, until in 1869 James Oliver of South Bend, Indiana, turned out the first chilled-steel plow.
Why did farmers reject Newbold’s plow?
选项 A、They preferred lighter tools.
B、It was too heavy.
C、They thought it would ruin the land.
D、It was too expensive.
答案C
解析 本题仍是一道具体细节题。问农民们为什么不接受纽波德发明的铁犁。利用查阅式阅读法，我们可以很快在文章的第二段后半部分找到相关信息。这部分指出，早在1790年，新泽西州的查尔斯·纽波德便搞起了铸铁犁的研制，并把其所有财产都用于推广他的发明上。然而，农民们并未把他的发明当做一回事，他们声称铁犁毒害土壤，增生杂草。由此我们可以推断出本题的正确答案应是C“因为他们认为铁犁会毁坏土地”。
