__ he was a boy,Pele had a dream.为什么填Ever since 能填 while 有什么
1个回答

应该是:

1 When he was a boy,Pele had a dream.------when搭配“一般过去时”.

2 Ever since he was a boy,Pele has had a dream.-------有 since 的参与,你必须用“现在完成时”.

3 While he was a boy,Pele had a dream.----- when搭配"一般过去时".

4 He SAID that he HAD HAD a dream SINCE boyhood.-------主句that 句子(since +过去完成时)

5 在你的语境中,when和while的使用没有区别.
