问题     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)_____.


选项 A、operates
B、works
C、starts
D、goes

答案B

解析 整句话的理解。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,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。starts"开始"具有一定的迷惑性,但放在这句话中没有works准确。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operates"运转,开动"和goes"进行"均不符合题意。
