一道英语语法题目啊,这题选哪个啊?Five hundred million different species of living creatures have appeared on Earth,nearly 99 percent of them vanishing.(A)Five hundred million different species of living creatures hav
网友回答
选EB：前面有nearly 99% of,后面的five hundred million different species是特指,需要加定冠词the,所以不能选
C：vanish是不及物动词,不能用被动语态,所以不能选.
D：前面的of结构和后面主句中的of them重复了,造成句子的冗余,所以不能选.
