When I was growing up, I had an old neighbor, Dr. Gibbs. He didn't look like any doctor I'd ever known. He never invited us to play in his yard, but he was a very kind 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(毁坏) them, and that if you watered them, each baby tree would grow weaker and weaker, so you had to make things difficult for them and pick out the weaker trees early on.

He talked about how watering trees made for shallow(浅的) roots(根), and how trees that weren't watered had to grow deep roots in search of water under the earth by themselves. Deep roots were very important. So he never watered his trees. He'd planted an oak(橡树)and instead of 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 after I left home. Every now and then, I walked by his house and looked at the trees that I watched him plant about twenty-five years ago. They're very big and strong now. I planted some trees a few years back and carried water to them for a whole summer. After two years of caring too much, whenever a cold wind blows in, they shake 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 blowing somewhere, so what 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 could face it strongly and won't be beaten down.

WARNING: Holding a cell phone against your ear or putting it in your pocket may be bad for your health.   

This sentence is a warning that you’d better not put it close to you when a new phone is bought. Apple company, for example, doesn't want IPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's producer, recommends 2.5 centimeters.

(1)If cell phone use can        health problems, the         will be very serious. Americans spend 2.26 trillion minutes chatting on cell phones every year, which brings $109 billion for the wireless businessmen.

Devra Davis, an epidemiologist(皮肤病专家) who has worked for the University of Pittsburgh, has published a book about mobile phone radiation(辐射)"Disconnect." Davis studies how often brain cancer happens during different age groups. She finds a big increase in brain cancer in the 20-to-29 age group and a drop for the older people.

Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.

Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency(电波频率)radiation had destroyed DNA in their brains.

Ms. Davis recommends using wired earphones(有线耳机)or the phone's speaker. (2)Children should send text messages rather than call, she said, and pregnant(怀孕的) women should keep phones away from their bodies.
