by then，到那时为止，by接时间，表示到。。。时为止。正是因为这个时间状语，所以才用完成时，又因，then是将来的某一时间，所以是将来完成时
for 20 years，是完成时的时间状语，表示某一行为或状态已经持续了多长时间...

将来完成时
marry是及物动词，必须用被动式
by then，到那时为止，by接时间，表示到。。。时为止。正是因为这个时间状语，所以才用完成时，又因，then是将来的某一时间，所以是将来完成时
for 20 years，是完成时的时间状语，表示某一行为或状态已经持续了多长时间

是将来完成时
如果用have married就是结婚这个动作持续了20年，因此用been married表示结婚的状态持续了20年
by then 到那个时候
for+时间表示持续多长时间
