difference前面用什麼冠詞

前面用冠詞the，例如：

1、She found it difficult to get on with her， possibly because of the difference in their ages.她覺得很難與她相處，這可能是因為她們年齡上的差距。

2、When they had married， six years before， the difference in their ages had seemed unimportant.他們6年前結婚時，年齡的差距似乎並不重要。

前面的冠詞不同 一個是a 一個是an。difference是指差異、不同，也有影響的意思，influence就只有影響的意思了。
