因?yàn)榫渥又杏忻黠@表明時(shí)間的詞語(yǔ)by
一般看到by the time就兩種時(shí)態(tài)：過去完成時(shí)和將來(lái)完成時(shí)
by the time后面為一般現(xiàn)在時(shí),說(shuō)明事情還未發(fā)生,所以用將來(lái)完成時(shí)
也就是A

A：will have been down B：is down C：had been downD：would have down 選什么 為什么啊
A：will have been down B：is down C：had been downD：would have down 選什么 為什么啊
