完型填空。
     When I was growing up, I had an old neighbor, Dr. Gibbs. He didn't look like any   1   I   2  . He never
invited us to play in his yard,but he was a very   3   person.
     When Dr. Gibbs wasn't saving lives, he was planting trees. He owned a large field and wanted to make
it a forest.
     The good doctor had some interesting ideas about planting trees. He never watered his new trees. Once
I asked why. He said that watering plants spoiled them, and that if you   4   them, each baby tree would grow
weaker and weaker, so you had to make things difficult for them and   5   the weaker trees early.
     He talked about how watered trees grew shallow (浅的) roots, and how trees that weren't watered had
to grow deep roots in search of water   6   the earth by themselves.   7   roots were very important.
     So he never watered his trees. He'd planted an oak and,   8   watering it every morning, he'd beat it with
a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.
     Dr. Gibbs died several years   9   I left home. Every now and then, I walked by his house and looked at
the trees  10  I watched him  11  about twenty-five years ago. They're very big and strong now. I planted
some trees a few years later and carried water to them for a whole summer. After two years of  12  too much,
whenever a cold wind blows in, they  13  a lot.
     Every night before I go to bed, I check on my two sons. Mostly I pray (祈祷) that their lives will be easy.
But lately I've been thinking that it's time to change my prayer. I know my children are going to face difficulties.
There's always a cold wind  14  somewhere, so  15  we need to do is to pray for roots that reach deep into the
brave heart, so when the rains fall and the winds blow, we can face it strongly and won't be beaten down.
