题目

the question of whether certain chemical fertilizers are a curse or are they a blessing is still?
the question of whether certain chemical fertilizers are a curse or are they a blessing is still being debated?
出自sat语法,这句话是对的吗?我认为是不是is still being debated错了?

答案

把ARE THEY去掉吧
虽然语法没有问题,但是加上ARE THEY不符合语言习惯
is still being debated是正确的
