不知不觉我又长大了一岁英文怎么写

Without realizing it,I grew/became one year older.
I didn't realize that I'm one year older.
unconsciously表示：没有经过安排的,没有经过计划的,without conscious intent,强调没有意图Without conscious control; involuntary or unintended.而不知不觉表达的是事情的发生没有引起注意,这中间的区别还是不小的.

unconsciously I'm one years older now.
unconsciously是unconscious的副词形式
意思为不知不觉的

I am unaware of being 1 year older.
