So loudly ______that people could hear it out in the street.

A、 did the students play the music
B、 the students playing the music
C、 the students played the music
D、 have the students played the music

【正确答案】 A

【答案解析】解析：本题考查的是倒装句型。当从属连词so…that和such…that中的so和such位于句首时，句子要部分倒装，助动词提前，意思是“如此……以至于”，故A项为正确答案。又如：So happy was the girl that she jumped up and down like a rabbit．(这个女孩是如此得开心，以至于像兔子一样蹦跳起来。)
