问题 In the following text, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list (A、B、C、D、E、F、G……) to fit into each of the numbered blank. There are several extra choices, which do not fit in any of the gaps. (10 points)

    (41)______. We created rebellions by workers who were fearful that the machines would rob them of their work. Patrick Bell, in Scotland, and Cyrus McCormick, in the United States, produced threshing machines. Ingenious improvements were made in plows to compensate for different soil types. Stream power came into use in 1860s on large farms. Hay rakes, hay-loaders, and various special harvesting machines were produced. Milking machines appeared. (42)______.
    (43)______. Between 1940 and 1960, for example, 12 million horses and mules gave way to 5 million tractors. Tractors offer many features that are attractive to farmers. There are, for example, numerous attachments: cultivators that can penetrate the soil to varying depths, rotary hoes that chop weeds; spray devices that can spray pesticides in bands 100 feet across, and many others.
    A piece of equipment has now been invented or adapted for virtually every laborious hand or animal operation on the farm. In the United States, for example, cotton, tobacco, hay, and grain are planted, ’treated for pests and diseases, fertilized, cultivated and harvested by machine. Large devices shake fruit and nut from trees, grain and blend feed, and dry grain and hay. Equipment is now available to put just the right amount of fertilizer in just the right place, to spray an exact row width, and to count out, space, and plant just the right number of seeds for a row.
    (44)______. Agriculture innovation is accepted fastest where agriculture is already profitable and progressive. Some mechanization has reached the level of plantation agriculture up parts of the tropics, but even today much of that land us laboriously worked by people leading draft animals pulling primitive plows.
    The problems of mechanization of some areas are not only cultural in nature. For example, tropical soils and crops differ markedly from those in temperate areas that the machines are designed for, so adaptations have to be made. (45)______.

A. Mechanization is not used in agriculture in many parts of Latin America, Africa.
B. Only after the adaptations have been accomplished can all the new machines be used in the areas.
C. The internal-combustion engine run by gasoline became the chief power source for the farm.
D. But the greatest obstacle to mechanization is the fear in underdeveloped countries that the workers who are displaced by machines would not find work elsewhere. Introducing mechanization into such areas requires careful planning.
E. In time, the number of certain farm machines that came into use skyrocketed and changed the nature of farming.
F. The full influence of mechanization began shortly after 1850, when a variety of machines came rapidly into.
G. After 1850, science and technology came to a new era and developed very fast, many famous scientists born and made great achievements to the mankind.

选项
答案E
解析 这句话是第二段的起始句，可以先看明白本段中的内容。本段主要讲述的是各种各样的机械在农业中的使用，而且在注意到本选项中的"In time"一词和前文构成的承接关系，所以正确答案是E。
