小弟问一下一个英语问题
Eating fruit and vegetable is food for our health
Meat,fish,eggs and milk is very important to us
这几个句子为什么不用BE动词are,却用is
而Meat,fish,eggs and milk are all very important to us.这个句子却用are
答
fruit and vegetable 是一个专有名词，意思是果蔬，就像bread and butter黄油面包一样。但是meat,fish eggs and milk就不能构成一个词，是独立存在的了。
答
第一句话的主语不是蔬菜和水果,而是吃蔬菜和水果这件事,它是一个整体.
第二个应该是口语化表达,标准的应该是用are的~
