--- Is Tom still smoking?
--- No. By next Saturday he _____ for a whole month without smoking a single cigarette.

A．will go	B．will have gone
C．goes	D．has been going

答案

 B

解析

试题分析：考查时态：句意：--汤姆还抽烟吗？--没有，到下周六，他就一整个月没有抽任何一只烟了。时间是By next Saturday，by引导时间状语的句式中句子的时态用完成时态，因为是next saturday还没有到来，所以应该用将来时态，所以by next Saturday和在一起就是将来时态的完成时态，所以选B。
