優(yōu)質(zhì)解答
首先,第二個(gè)格字,in the past ,是完成時(shí)的提示詞,因此前面就用完成時(shí),has grown,同時(shí)排除AB,的 for the past 400 years,就錯(cuò)的,要么是for 400 years,要么是since past 400 years ago,同時(shí),也是完成時(shí)的提示詞D 的las...但是不是 for the past+時(shí)間段,表示在過去的……時(shí)間里,last|in the past+時(shí)間段,用與現(xiàn)在完成時(shí)么==for the past 400 years,沒錯(cuò),我一開始把past 看成了last 正因?yàn)橐猛瓿蓵r(shí),可是B 用了過去式,所以B 才錯(cuò)
