全年现金持有机成本=(60000/2)×5%=1500(元)
持有现金的总成本=1500+1500=3000(元)。

As a child, I was truly afraid of the dark and of getting lost; these fears were very real and caused me some uncomfortable moments.
Maybe it was the strange  26  things looked and sounded in my familiar room at night that 27  me so much. There was never total  28 , but a streetlight or passing car lights  29   clothes hung over a chair take on(呈现) the  30  of a wild animal. Out of the corner of my 31 , I saw the curtains seem to move when there was no  32 . A tiny sound in the floor would seem a hundred times louder than in the daylight. My  33  would run wild, and my heart would beat fast. I would  34  very still so that the “enemy” would not discover me.
Another of my childhood fears was that I would get lost,  35 on the way home from school. Every morning I got on the school bus right near my home .That was no  36 . After school, 37 , when all the buses were  38  up along the street, I was afraid that I’d get on the wrong one and be taken to some  39  neighborhood. On school or family trips to a park or a museum, I wouldn’t let the leaders out of my 40 .
Perhaps one of the worst fears  41  all I had as a child was that of not being liked or  42  by others. Being popular was so important to me  43 , and the fear of not being liked was a 44  one.
One of the processes(过程) of growing up is being able to  45  and overcome(克服) our fears. Understanding the things that frightened us as children helps us achieve greater success later in life.
