完形填空

When I was growing up, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d   36  known. When Dr. Gibbs wasn’t   37  lives, he was planting trees.
The good doctor had some   38  theories on planting trees. He believed in “No pains, no gains”. He never   39  his new trees, which was   40  many people. Once I asked why. He   41  that watering plants spoiled them, and that if you water them, each following tree generation will   42  weaker and weaker. So you have to make things   43  for them. He talked about how watering trees   44  shallow roots, and how trees that weren’t watered had to grow deep roots in   45  of water. I came to understand that he meant deep roots were to be   46 . I planted a couple of trees a few years back and I took good care of them. Two years of   47  has resulted in trees that expect to be waited on hand and foot. Whenever a cold wind blows, they   48  and tremble their branches. Funny things about those trees of Dr. Gibbs’. The lack of water seemed to   49  them in ways comfort and ease never could.
I used to   50  for my sons that their lives will be easy. But   51  I’ve been thinking that it’s time to   52  my prayer. I know my children are going to meet   53 , and I’m praying they will be strong. The prayer for comfort is seldom met. What we need to do is to pray for deep roots,   54  when the winds blow, we won’t be   55  away.
