during the last three decades,the number of people participating in physical fitness programs()sha
during the last three decades,the number of people participating in physical fitness programs( )sharply.这是一道选择题.答案是has increased 用现在完成时.因为during the last three decades.可是这句话:the girl has a great interest in sport and( )badminton classes twice a week over the last three years 此处却填has been taking 用现在完成进行时.为什么两者不一样呢?都是表达在一段时间内
希望回答的简洁易懂
用has been taking 现在完成进行时是为了强调动作的持续性,即三年来她一直这么做
而第一句中并不强调是持续增长的,只是为了说明现在比以前增长了许多,是起点与终点的比较,中途有轻微的下降也说不准
