you won't know if it fits you until you ___it on.A will try Bare trying Ctried Dhave tried
那这题选什么呢:
No one can be sure if the car on display fits him or her until he or she _____them.
A tries B will try C are trying D have tried
也请同样给出详细解释,并且对比两题,
D
not...until句型,直到...才.直到(某时)(某动作)才(发生)
直到你试了才知道它是否适合你.
主句用一般将来时,从句应该用一般现在时,选项中没有只能用D现在完成时表示动作对未来产生的影响.
