Although alcohol use is illegal for all those under the age of 21, 87 percent of high school seniors report using alcohol, more than half in the past month.
老师好,more than half in the past month省略了什么成分?
more than half in the past month 等于:
more than half high school seniors iusing alcohol in the past month
这个短语类似举例性质:在过去的一个月里情况怎样,上月饮酒情况是超过一半的人数。这是针对前文的“百分之八十七”而言的。超过了人数的百分之五十,也就快接近87%了,目的是证明87% 这个数字不差。
