all furniture是单数还是复数

all furniture是单数不是复数。因为furniture为不可数名词，中文意思是“所有的家具”

例如，因为我店里的家具美观又大气，质量有保障尤其是价廉物美，国庆节期间，因为促销活动，所有的家具都卖完。

For example, because the furniture in my shop is beautiful and atmospheric, the quality is guaranteed, especially the cheap and good quality. During the National Day, because of the promotion activities, all the furniture is sold out.
