    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”。
