Seventy percent of the area____ covered by flowers, three -fouths of roes.
A are ,which is B are,them are C is,which are D is,that is
A are ,which is B are,them are C is,which are D is,that is
不要被 senventy percent 和 three-fourths 所迷惑。这道题目的谓语单复数形式其实与它们无关。正确答案是 C。
area ，不可数名词，决定了 is
flowers, 可数的复数形式，决定了 are。
Seventy percent of the area is covered by flowers, three -fourths of which are roes.
再比如：
Seventy percent of the students in this class are girls.
尽管都是 senventy percent, 这里却需要使用复数。
three-fourths 也是类似的道理。关键决定于 主体本身的可数与不可数，单数还是复数。
