Ⅳ. 1.【解析】选B。由句中“food”可知C、D两项不符。Meat是不可数名词，无复数形式，排除A项。故选B。 
2.【解析】选A。两个或两个以上的不可数名词用and连接作主语时，谓语动词用复数形式。故选A。
3.【解析】选B。noodle是名词，意为“面条”，常以复数形式出现。noodles放在句首，第一个字母大写。故选B。
4.【解析】选C。根据上文，but在此处表示转折。故选C。
5.【解析】选B。根据常识，汉堡包和糖果是不健康食品。unhealthy“不健康的”，形容词，在此句中作定语。故选B。
6.【解析】选A。drink表示饮料的种类时是可数名词。此句含有三种饮料：水、牛奶和果汁。故选A。
7.【解析】选C。healthy是以辅音音素开头的单词，因此用a。故选C。
8.【解析】选B。句意：因此，为了健康，吃一些蔬菜、水果、米饭、面条、鱼和肉。故选B。
9.【解析】选C。句首的drink意思是“喝”，动词。说明喝的是饮料。选项中B项是食物，首先排除；由后句排除A项；juice意思是“果汁”，不可数名词，因此不能用复数形式，排除D项。故选C。
10.【解析】选C。 结合上文，此句意思是“不要喝太多的可乐。”此句是否定的祈使句，因此在祈使句前加don’t。故选C。
