【正确答案】
D
【答案解析】此题属于语义搭配题。switch意为“改变，交换”，如：switch position(改变立场)，又如；They switched the train to the other track. 他们将火车转到另一条轨道。原文中提到与铁路有关的一个场所，应是道岔所在地，有许多轨道，故选项D switching正确，意为“铁路车辆编组场”。选项A freight意为“货运”；选项B passenger意为“乘客”；选项C relaying意为“转播”。
【答案解析】此题属于语义搭配题。next to意为“仅次于……”，根据句子意思，此处需一个介词说明silicon和oxygen的关系。前半句谈到芯片主要成分是silicon(硅)，后半句谈oxygen(氧)是地壳中含量最丰富的元素，因此，next to(仅次于)才能说明硅和氧的关系。故选项B next to正确。选项A like意为“与……一样”，与题意不符；选项C in the neighborhood of意为“大约”，体现不出二者含量的差别；选项D same as意为“与……一样”。
【正确答案】
D
【答案解析】此题属于语义搭配题。the vast/great majority of…意为“绝大多数”；其他选项：A wide；B deep； C long均不能与majority连用。
【正确答案】
A
【答案解析】此题属于语义搭配题。mass produce意为“批量生产，规模化生产”，故选项A mass正确。选项B scale意为“规模”，多见于a large-scale business或business on a large scale；选项C scope意为“领域，范围，余地”；选项D wide意为“宽的”，不能与produce连用。
【答案解析】此题属于语法题。over the past few years意为“在过去的几年中”，选项B over符合语法和题意。其他选项：A before，C after和D since均不符题意。
【正确答案】
C
【答案解析】此题属于语义搭配题。take over意为“取代，接收”，如：Who do you think will take over now that the governor has been dismissed? 州长被免职了，你看谁会接任?原文中提到工业革命对人类体力劳动所起的作用。只有“接收，取代”比较符合题意，故选项C took over正确。选项A resort to意为“诉诸于，利用”，例如：When his girlfriend left him he resorted to drink. 女朋友离去后，他借酒浇愁。选项B succeed to意为“继承”，如：to succeed to the property；选项D left over意为“剩下”。
【答案解析】so此题属于语法题，just as…so…意为“正如……一样”，从属复合连词；根据原文内容，比较工业革命和计算机对人类的影响，前半个分句中出现了just as…，后半句就应是so与之连用，故选项D so正确。选项A therefore(因此)，表因果；选项B thus副词，有“如此”之意，但不与just as连用，例如：We hope the new machine will work faster, thus reducing our costs. 选项C however表转折。
【正确答案】
A
【答案解析】此题属于语篇衔接题。thereby意为“因此”，较正式，如：We became a citizen，thereby gaining the right to vote. 根据原句内容，由于计算机承担了大量艰苦的脑力劳动，这样就有助于我们拓展大脑的能力，二者存在一种因果关系，故选项A thereby正确。其他选项：B otherwise表转折；C at least(至少)；D inversely(相反的)。
【正确答案】
C
【答案解析】此题属于词语搭配题。in ways意为“在……方面”；field，aspect，area都解释为“方面，领域”，但前面的介词应是in，故其他选项：A at fields，B on aspects和D for areas均不符题意。
【正确答案】
A
【答案解析】此题属于语法题。with意为“具有……”，with the chip amazing feats of…意为：有了这种超强功能的芯片，故选项A with正确。其他选项：B after，C within和D despite均不符题意。
【正确答案】
B
【答案解析】此题属于语篇推理题。根据文章内容，芯片虽小，但功能强大，主要体现在记忆和计算方面，故选项 B memory and execution正确。选项A wonder and enjoyment意为“奇迹和乐趣”；C adjustment and repair意为“调节和维修”；D manual and mental labor意为“体力与脑力劳动”。
