英文百分比与百分点表达上的区别
如题
也有网友说是一样的,在英语表达中没有区别,都是“increased by 7.3 present” 是真的吗
例句：CPI decreased by 1.2 percent in May 2010 compared to the previous month.（这是百分比还是百分点?）
the index of "food and nonalcoholic beverage" group experienced a decrease of 3 percent during the period under study.这是百分比还是百分点?
请重点阐述二者在英文表达上的区别
答
decreased by 1.2 percent 是百分比；a decrease of 3 percent 是百分点.关键看前面用的是动词还是名词,用动词+by是百分比,用名词是百分点.
