题型:完形填空
I am a team leader in an insurance company. We are going through a lot of changes right now, which is   36  much stress for all of us.
A few weeks ago I was having a day so   37  that I even doubted if I had the ability to do this challenging work, and was about ready to change to a less stressful job   38  . Something happened that day to change my way of   39  and I am so appreciative of this young lady. I want to let her know that the small act   40  .
On the top of my cubicle (工作隔间) I have a small collection of lighthouses (灯塔) to let people know where I am sitting   41  my team members have to find me for emergencies.
That day I came into the office and was about to get the day   42  when Crystal came over. I asked if she needed anything. And she said, “I   43  you something.” I looked at her with a   44  look and said, “Well, thank you, but why   45  you buy me anything?” I had never spoke to this young lady   46 . She said, “Every day I stand up and look across the     47  and see your lighthouses. Then I feel I am not alone and I encourage myself that there are always   48  things in life. I saw this on the way to work and thought   49  would like it. I wish it would have the same   50  as your lighthouses do.” In her hand she had a small globe with a lighthouse and a ship on it. I gave her a hug and   51  her. I don’t think she knows how much that small act of   52  changed my day: I remained   53  the rest of the day.
For anyone that reads this, I hope you remember, no matter what the   54  is, you could change someone’s day,   55  even his views on life.
