Prof. Brown gave us_____. a.a piece of advices b.some advices c.some pieces of advice
d. some pieces of advices
答
C，advice为不可数名词，一点建议，a piece of advice,复数为some pieces of advice
答
选C，说advice没有复数不准确，而是advice是不可数名词，所以不能用复数，英语中大部分抽象名词都是不可数，advice建议就是个抽象名词。。
希望能帮到你，祝你进步！
答
c.some pieces of advice
advice没有复数
