-------must have been hard for the lady. She looks much older than her age.
A.The time
B.Time
C.The times
D.Times
请详解，谢谢!

选C.
原因： time ：在这里指的是过去的那一段时间，因此前还加了定冠词the，用此意时常用复数。在此的它的英文含义就是：An interval, especially a span of years, marked by similar events, conditions, or phenomena; an era. Often used in the plural（复数）。比如：hard times（艰难时期）; a time of troubles（麻烦不断的时期）.
times ：在复数的情况下，还表示一个时代。英文含义就是：The present with respect to prevailing conditions and trends。比如， You must change with the times.你必须随着时代的变化而变。


希望以上解释能对你有所帮助。
