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、opened up
B、come up
C、turned up
D、gone up
答案A
解析 整句话的理解。opened up"(使某物)打开，张开"，把opened up填入空格中的意思是开启一个全新的无线世界，符合文意。turned up意思是"出现，发生"，与opened up相比，缺乏生动性，所以排除。come up"长出，发芽"和gone up"上升，增长，建起"均不符合题意，排除。
