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、mainly
B、entirely
C、absolutely
D、probably
答案D
解析 整段的理解。这个项目在进行研究的过程中可能会遇到各种问题，而这些问题不能预知，所以probably"很可能，大概"符合题意，入选。entirely"完全地"和absolutely"绝对地"太绝对化，所以排除。mainly"主要地"不符合题意，排除。
