【单选题】The agriculture 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. "InEurope", said Thomas Jefferson, "the object is to make the most of their land, labor being sufficient; here it is to make the most of our labor, land being abundant. " It was inAmerica, therefore, that the great advances in nineteenth — century agricultural machinery first came.At the opening of the century, with the exception of a crude (粗糙的) plow, farmers could have carried practically all of the existing agricultural tools 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 1890Charles Newbolt 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 home 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 SouthBend, Indiana, turned out the first chilled-steel plow. It is implied but not stated in the passage that_________.
A、there was a shortage of workers onAmerican farms

B、the most important of the early invention was the iron plow

C、after 1869, many people devoted their attention to the plow
D．Charles Newbolt had made a fortune by his cast-iron plow

本题是推断题，也是对文章细节的考查。根据“In Europe…the object is to make the most of their land，labor being sufficient；here it is to make the most of our labor，and land being abundant．(在欧洲……我们的目标是劳动力充足，要充分利用土地；在美国土地充足，要正确使用劳动力。)”可推知“美国缺乏劳动力。”B在文章中“The most important of the early inventions was the iron plow．”有说明；根据“many people devoted their attention to the plow，until in 1869，James Oliver of South Bend，Indiana，turned out the first chilled steel plow．”可知C与此句意思相反，为错误项。根据“spent his entire fortune in introducing his invention．The farmers，However，would home none of it”可推知Charles Newbolt并没有因此而发财，D项也错误。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
