读写任务。

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

     When I was growing up, I had an old neighbor named Dr. Gibbs. He didn't look like any doctor I'd ever

known. When Dr. Gibbs wasn't saving lives, he was planting trees.

     The good doctor had some interesting theories concerning planting trees. He believed in "No pains, no

gains". He never watered his new trees, which was beyond many people. Once I asked why. He answered

that watering plants spoiled them, and that if you water them, each following tree generation will grow weaker

and weaker. So you have to make things tough for them. He talked about how watering trees made for shallow

roots, and how trees that weren't watered had to grow deep roots in search of water. I took him to mean that

deep roots were to be treasured.

     So he never watered his trees. He'd plant an oak (橡树) and, instead of watering it every morning, he'd

beat it with a rolled-up newspaper. Smack! Slap! Pow! I asked him why he did that, and he said it was to

get the tree's attention.

     Dr. Gibbs passed away a couple of years after I left home. Every now and again, I walked by his house

and looked at the trees that I'd watched him plant some twenty-five years ago. They're extremely tall, big

and strong now. Those trees wake up in the morning and beat their chests and drink their coffee black.
