以下名词为不可数名词：
news(消息) information(信息)
furniture (家具) equipment(设备)
advice (劝告) weather(天气)
work*(工作) clothing(衣服)
baggage(行李)
work作 "工作" 解释时为不可数名词，"找工作"不能说to find a work, 应为to find a job; work作"着作"、"作品"解时是可数名词，如：Deng Xiaopin's works (邓小平着作)/ a work about Deng Xiaopin (一件关于邓小平的作品);作 "工厂" 解释时，单复数同形：a steel works (一个钢铁厂) / two chemical works(两家化工厂)
实例：
We have a large staff but there ______ in the office.
A. haven't many furnitures
B. aren't many furnitures
C. hasn't much furniture
D. isn't enough furniture
解题思路：根据名词数的概念A、B肯定错，不必考虑;C、D的主要差异是"hasn't"与 "isn't", 句子中有there，说明该句是there be句型，故正确答案为D.题中staff, office 等词与解题无关。
注意辨别句子中斜体词的数及其意义：
There is still much room for improvement. (仍有许多改进的余地)
He has published two important papers on this subject. (他在这个课题上已发表了两篇重要论文。)
