The nineteenth century brought about the greatest expansion of wealth the world had ever known. Its sources lay in the industrialisation of Europe and the techniques for assuring the continuance of this growth were by no means exhausted or compromised in 1900. There had not only been a vast and accelerating flow of commodities available only in (relatively) tiny quantities a century before, but whole new ranges of goods had come into existence. Oil and electricity had joined coal, wood, wind and water as sources of energy. A chemical industry existed which could not have been envisaged in 1800. Growing power and wealth had been used to tap seemingly inexhaustible natural resources, both agricultural and mineral. Railways, electric trams, steamships, motor cars and bicycles gave mil-lions of men a new control over their environment; A. after 1900 B. before 1900 C. in about 1800 D. in about 1900 查看答案 更多"{{B}}TEXT B{{/B}} The n"的相关试题: [单项选择]{{B}}TEXT B{{/B}} The nineteenth century brought about the greatest expansion of wealth the world had ever known.

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 sufficient; 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 (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 1890 Charles Newbolt of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in A. The need for labor helped the invention of machinery in America B. The farmer rejected Charles Newbolt’s plow for fear of ruin of their fields C. Both Europe and America had great need for farm machinery D. It was in Indiana that the first chilled-steel plow was produced 查看答案 我来回答: 提交 最新试题 ●    [单选题]绝缘靴、绝缘手套等安全用品，应( )年进行一次绝缘耐压试验，并存放在阴凉干燥、防尘处所。 ●    [单选题]驾驶叉车起步不须鸣笛。 ●    [多选题]在有燃烧爆炸危险的场所进行起重破拆作业时，应采取（ ）措施。 ●    [判断题]当模拟量检测值超限 需报警或断电 断电命令与馈电状态不符或开关量状态为报警状态时需要系统发 ●    [单选题]科目汇总表账务处理程序一般适用于( )7-204 ●    [单选题] （ ）是指按一定的应用条件进行设计计算，将灭火剂从储存装置经由干管、支管输送至喷放 网站地图 我要搜题网  版权所有  ©2023  湘ICP备18016427号   购买搜题卡查看答案 [会员特权] 开通VIP， 查看 全部题目答案 [会员特权] 享免全部广告特权 推荐91天 ¥36.8 ￥80元 31天 ¥20.8 ￥40元 365天 ¥88.8 ￥188元 请选择支付方式 微信支付 支付宝支付 点击支付即表示同意并接受了《购买须知》 立即支付 系统将自动为您注册账号 已有账号登录 找回账号密码 请使用微信扫码支付 订单号： 请不要关闭本页面，支付完成后请点击【支付完成】按钮 支付完成 取消支付 恭喜您，购买搜题卡成功 系统为您生成的账号密码如下： 账号 密码 重要提示：请拍照或截图保存账号密码！ 我要搜题网官网：https://www.woyaosouti.com 我已记住账号密码
