高一英语 时态填空（2）

the country life he was used to ________(change) greatly since 1992.
up to now ,the program ____________(save)thousands of children who would otherwise have died.
each of the students working hard at their lessions ________________(read)the books.
for many years,people ________(dream)of electric cars.
最好有解释 谢谢

Answer 1

1. has changed.   因为since 1992 是现在完成时时间状语

2. has saved。 up to now是缺亏现在完冲尘成时的时间状语

3. has read。 这是强调影响和结果，所以用现在完成时。（现在完成时的散扮禅定义）

4. have dreamed. 现在完成时的时间状语for+一段时间。

   这些题都是考察现在完成时的用法。

追问

2. 后面有一个 would 难道不是过去完成时吗？ 能不能写had saved??

追答

那个would是定语从句who里面的时态，跟主句无关啊。主句的时态由主句的时间状语决定。

Answer 2

has changed 他习惯的乡村生活在1992年后发生了巨大的变化
has saved到现在为止，这个程序已经拯救了数以千记滑码郑的孩子生命
has read每个孩信颂子在课上都认真读书
have been dreaming 人们幻想汽车很多年了
