Question

The invention of the electric telegraph gave birth to the communications industry.Although Samuel B．Morse succeeded in making the invention useful in 1837，it was not until 1843 that the first important telegraph line was constructed.By 1860 more than 50,000 miles of lines connected people east of the Rockies.The following year，San Francisco was added to the network.
The national telegraph network strengthened the ties between East and West and contributed to the rapid expansion of the railroads by providing an efficient means to monitor schedules and routes.Furthermore，the extension of the telegraph，combined with the invention of the steam－driven rotary printing press by Richard
M．Hoe in 1846，revolutionized the world of journalism.Where the business of news gathering had been dependent upon the mail and on hand－operated presses，the telegraph expanded the amount of information a newspaper could supply and allowed for more timely reporting.The creating of the Associated Press as a central wire service in 1846 marked the arrival of a new era (紀(jì)元) in journalism.

Answer 1

【小題1】C
【小題2】A
【小題3】B

解析試題分析：本文主要講述了美國(guó)電報(bào)業(yè)的發(fā)展歷程以及它和railroads的發(fā)展之間的關(guān)系。
【小題1】C 主旨大意題。本文在第一段主要講述了電報(bào)的發(fā)展歷程。在第二段1,2行The national telegraph network strengthened the ties between East and West and contributed to the rapid expansion of the railroads by providing an efficient means to monitor schedules and routes.說(shuō)明電報(bào)業(yè)的發(fā)展也加強(qiáng)了美國(guó)東西方的railroads的發(fā)展。故C項(xiàng)正確。
【小題2】A推理題。文章第一段中詳細(xì)描述了在各個(gè)時(shí)期美國(guó)的電報(bào)業(yè)的發(fā)展情況，在后幾段又提及了美國(guó)歷史上的鐵路的發(fā)展，故最有可能是從一部關(guān)于美國(guó)的歷史的書(shū)上摘錄下來(lái)的。故A正確。
【小題3】B 推斷題。根據(jù)文章2,3行Although Samuel B．Morse succeeded in making the invention useful in 1837，it was not until 1843 that the first important telegraph line was constructed.說(shuō)明在1837年Morse就讓這個(gè)發(fā)明有用了，知道1843年才有了第一根電話線。說(shuō)明他的發(fā)明沒(méi)有立刻就起作用。故B項(xiàng)正確。
考點(diǎn)：考查歷史知識(shí)類(lèi)短文閱讀
點(diǎn)評(píng)：本文主要講述了美國(guó)電報(bào)業(yè)的發(fā)展歷程以及它和railroads的發(fā)展之間的關(guān)系。以推理題的考查為主，要求考生在仔細(xì)研讀文本內(nèi)容的情況下結(jié)合題目要求和選項(xiàng)內(nèi)容作出合理的判斷。
