本题考查名词词义的辨析。空格处填入的名词充当extending them to结构中的介词宾语,其中extend...to...意为“扩展……用于……”,them指上文中的its commercial spaces(东日本铁路的商业空地)。因此,所填的名词应与前文一致,表达这些空地的用处或功能,应与use的名词形式usage属同一范畴。 [A]、[C]项都有“使用”的意思,但application常与“科技成果、理论、法规”等搭配,强调它们的实际应用,一般不与spaces搭配,如 The new invention would have a wide range of applications in industry(这项新发明会在工业上获得广泛应用),[C]项functions“功能,作用”正确,即“还要把这些商业空地用于更加适应信息时代的功能上”。enterprise“企业,事业,计划”;performance“履行,执行,性能”。
