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. [br] The word "naturally" as used in the second sentence is closest in meaning to which of the following?

选项 A、Unsurprisingly.
B、Safely.
C、Apparently.
D、Gradually.

答案 A

解析本题是一道词语含义题。问第二句话中naturally一词与下面所给的四个选项哪个意思最接近。根据文章上下文，19世纪的农业革命涉及两个方面：一是节省劳动力的机器的发明；二是科技农业的发展。节省劳力的机器自然先从那些劳动力缺乏的地区出现。由此我们可以推知此词的含义是表示“自然而然地，自然地”。所以，本题的正确答案应是A“丝毫不令人惊讶地，理所当然地”。
