In 1971, an engineer working for Intel realized that a 【23】______ of circuits commissioned for an electronic calculator could all be put 【24】______ one chip, and that the resulting device could be used 【25】______ a general-purpose "computer on a chip". The result was the Intel 4004 -- the world’s first microprocessor. Physically, it consisted of a silicon chip in a protective ceramic capsule, with a set of metal pins sticking 【26】______ that connected it to other components in whatever 【27】______ it controlled. It 【28】______ 2,300 transistors, 【29】______ 60,000 operations per second, and could be used for any device -- including computers and robots -- that required a "brain" for accepting 【30】______ and following a program of 【31】______ to produce an output. Within five years, many very powerful microprocessors had 【32】______ .The invention of microprocessors 【33】______ the stage for the arrival of the microcomputer, or personal computer (PC)-- an affordable machine for 【34】______ The first PCs, in kit form, appeared in the mid 1970s, and by the mid-1980s machines such as the Apple Macintosh and those based 【35】______ a PC first 【36】______ by IBM in 1981 were popular throughout the world.

选项
A、part
B、particular
C、especially
D、special
答案
B

in与part搭配,意为“部分地”;in与particular搭配,意为“尤其”,与C含义相同,但in不能和C、D搭配。下文进一步强调上丈提到的.“软件爆炸”的具体各个层面,用in particular连接符合逻辑意义。故选B。
