单选题
The small size of the components of computer chips has proved unstoppable. In each new (1) , those components are smaller and more tightly packed than they were in their predecessor. (2) has been so rapid that chip designers are (3) apparently fundamental barriers to further reductions in size and increases in density. In a small size version of the (4) to wireless communication in the macroscopic world, a group of researchers led by Alain Nogaret, think they can make chips (5) components talk to each other wirelessly. The researchers (6) to use the standard print techniques employed in chipmaking to coat a semiconductor with tiny magnets. These magnets will (7) local magnetic fields that point in opposite directions at different points (8) the chip's surface. Electrons have a (9) called spin--that is affected by magnetic fields, and the team hopes to use a/an (10) called inverse electron-spin vibration to make electrons (11) the chip emit microwaves. Dr. Nogaret imagine great advances that would stem (12) the success of his work, and these are not (13) to the possibility of packing components yet more tightly. In today's chips, the failure of a single connection can put the whole circuit out of (14) . This should not happen with a wireless system (15) it could be programmed to re-route signals. The project will not be (16) sailing. Generating microwaves powerful enough to (17) data reliably will (18) involve stacking several layers of magnets and semiconductors together and encouraging the electrons in them to move in a harmonious union. But if it (19) , a whole new wireless world will be (20) .
【正确答案】
D
【答案解析】[直击题眼] predecessor的意思 [深层剖析] predecessor的意思是thing that has been followed or replaced by sth.else“前任,前辈,被接继或被取代的事物”,而[D]generation的意思是“一代”,放入此空句意为“新一代芯片的元件越来越小,压缩也越来越紧密”,符合文意。 [主干扰项分析] [A]relation“关系”、[B]consideration“思考”、[C]information“信息”均不符合文意,排除。
【答案解析】[直击题眼] 上下文的理解。 [深层剖析] 上一段中提出研究小组的观点,这一段阐述了研究小组开展研究工作,而[C]intend的意思是“打算,意欲,想要”,符合题意。 [主干扰项分析] [A]manage to do 的意思是“设法,达成”,侧重于指经过很大的努力、克服了很多困难、想方设法做成什么事情,不如“打算”贴切文意。 [次干扰项分析] [B] turn to 的意思是“使(某人或某物)变成,成为”,[D] like to do的意思是“喜欢做某事”,均不符合题意,排除。
【正确答案】
A
【答案解析】[直击题眼] magnets,local magnetic fields之间的关系。 [深层剖析] magnets“磁铁”可以产生local magnetic fields“局部磁场”,所以此处应该填有“产生”含义的词, [A]generate“使(某物)存在或发生,产生”符合题意。 [主干扰项分析] [D]grow的意思是“生长、增加、变大”,磁铁产生磁场,而不是生长为磁场,故排除。 [次干扰项分析] [B]discover“发现”、[C]make“制作”均不符合题意,排除。
【答案解析】[直击题眼] 整句话的理解。 [深层剖析] 由于受磁场影响电子可以旋转,这可以说是电子的一个特性,而[D]property的意思是special quality or characteristic of a substance,etc,“(物质等的)性质,特性”,正符合题意。 [主干扰项分析] [A]reality“真实、现实”、[B]opportunity“机会”、[C]prosperity“富足、繁荣”均不符合题意,排除。
【答案解析】[直击题眼] stem与介词的搭配。 [深层剖析] stem from的意思是arise from sth.,have sth.as its origin or cause“来自或起源于某物,由某物造成”,即从此项工作的成功中得到重大突破,符合题意,故[B]from入选。 [主干扰项分析] [A]for、[C]of、[D]to均不能和term搭配,排除。
【答案解析】[直击题眼] 整句话的理解。 [深层剖析] 此处题意是“如果这个项目______,就能有一个全新的无线世界”,答案显而易见,应该是成功,[B]works的意思是have the desired result or effect(on sb./sth.)“(对某人或某事)产生预期的结果或作用)”,符合题意。 [主干扰项分析] [C]starts“开始”具有一定的迷惑性,但放在这句话中没有[B]works准确。 [次干扰项分析] 最后一段作者首先提出项目的进行不会很顺利,并阐述项目一帆风顺的条件;最后提出将开启一个全新的无线世界,故[A] operates“运转,开动”和[D]goes“进行”均不符合题意。
