有两个问题（加粗黑体字），麻烦大伙讲解一下：
两个不可数名词放在一块做主语谓语动词用单数还是复数？
假如用单数，那样为何这句话用复数？Cola and candy are very sweet
假如用复数，那样为何这句话用单数？A lot of ice cream, hamburgers and cola is not healthy.
同理，那两个动词放在一块做主语谓语动词用单数还是复数？
以下文字引述自外研版初一上册Module 4 unit 2
Is your food and drink healthy? A lot of ice cream, hamburgers and cola is not healthy. Meat is healthy but too much meat is not good for children. Cola and candy are very sweet, and too much sugar is bad for you.
Eat the right food and be healthy. Carrots, eggs and sweet potatoes are good for your eyes. Milk, cheese and fish are good for your teeth. A bit tired? Have lots of delicious chicken soup! It is important to remember: eat well, stay healthy, and dont get fat!
并列的不可数名词作主语时，可用复数也可用单数，但侧重点不同，这要看说话者的主观意愿或意向。
1.假如将并列的不可数名词视为不一样的事物或物质，谓语动词用复数。比如：
Oil, natural gas, and coal are not equally available and distributed worldwide.石油、天然气和煤炭在全球的提供和分布并不均等。
2.假如将并列的不可数名词视为一个整体，谓语动词用单数。比如：
Bread and butter is my favorite breakfast.面包和黄油是我最喜欢的早餐。
比较：Both Bread and butter are all sold out.面包和黄油都卖完了。
