accommodation用法的正误

这个城市的住房很贵。
误：An accommodation is expensive in this city.
正：Accommodation is expensive in this city.
正：Accommodations are expensive in this city.
析：accommodation 表示“住处”、“住宿”、“膳宿”等，在英国英语中是不可数名词，但在美国英语中通常用复数，一般不与不定冠词连用。如：This hospital has accommodation(s) for 500 patients.(这家医院有五百个床位)。They providegood accommodation(s).他们提供很好的膳宿服务。
