The population_very fast_four hundred years.A grew,in the past B grew,for the past C has grown,in the past D has grown ,last答案给的是C,为什么啊==
The population_very fast_four hundred years.
A grew,in the past B grew,for the past C has grown,in the past D has grown ,last
答案给的是C,为什么啊==
The population_very fast_four hundred years.A grew,in the past B grew,for the past C has grown,in the past D has grown ,last答案给的是C,为什么啊==
首先,第二个格字,in the past ,是完成时的提示词,因此前面就用完成时,has grown,同时排除A
B,的 for the past 400 years,就错的,要么是for 400 years,要么是since past 400 years ago,同时,也是完成时的提示词
D 的last 400 years 是过去式的提示词,可是用了完成时,因此错
解释:首先看看后面一个空格的答案,在过去的四百年时间里面 in the past four hundred years.有介词in的才对!!可以排除BD答案了。
既然是过去的四百年时间,就是完成时态了 ,时态对的只有C has grown,in the past
望满意
in the past+时间段做时间状语,用完成时态。
The population has grown_very fast in the past_four hundred years.表示过去时的意思。
首先要明白出题者考点意图
in the past 与现在完成时态连用,这个是固定用法,没什么好解释的。 所以选C
句意:在过去的400年里,人口增长非常迅速!
