Fear is a fact of life everyone faces from time to time. In most cases fear is a healthy reaction to a dangerous situation. But sometimes fear can be so extreme, so overwhelming that it interferes with normal living. That is what happened to me driving cross-country last summer.
I’d agreed to help my brother, Mac, move from the East Coast to California. He would drive a rental truck loaded with his belongings and I would follow him in his sedan, then fly back. We figured it would be a simple trip, with four or five motel ( 摩托旅馆 ) stops along the way.
Living and working in coastal Georgia for most of my life, I didn’t have a great deal of long-distance driving experience. Looking back on it today, I can see that I’d always felt a twinge of fear when driving over small bridges and along hilly highways. And as I was getting ready for the trip I had a vague (模糊的)concern about the steep mountain roads that lay ahead. But I thought I would get used to them.
As we crossed some high bridges near the Blue Ridge Mountains on the first leg of our trip, a kind of breathlessness gripped（抓住）me, a sinking, rolling sensation in the pit of my stomach. I tended to veer slightly away from the edge of the roadway and thedrop-off beyond. My knuckles(手指关节) whitened from my tense grip on the steering wheel. At the end of each bridge, a great rush of relief would come over me, only to be replaced in short order by fear of the next obstacle.
When we stopped in Nashville the first night, I mentioned my feelings to Mac, who is the practical sort. “Oh, that’s nothing,” he said cheerfully. Lots of people hate driving on mountain roads and high bridges. Just turn up the music on your radio and focus on that. Keep your mind occupied.”

If you are afraid of the dark，it’s not a big deal．It’s perfectly normal to feel afraid After all，animals do too. “Fear matters，”says Karen Warkentin，an ecologist．“It’s a good thing，” she adds, “because fear makes you do things that keep you alive.”
Like kids，many animals experience fear and they respond to the feeling in variety of ways．A frightened turtle pulls its head and legs inside its shell．A small fish will swim away when a big，hungry fish approaches．
Some animals respond to fear in ways you might not expect．The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red—eyed tree frogs in Costa Rica.
In this species，female frogs attach jellylike clumps（果冻一样的块状物）of their eggs to the undersides of leaves．The leaves hang on branches that dangle（悬挂）over ponds．After they hatch from the eggs，the tadpoles（蝌蚪）then fall into the water，where they eventually grow into adult frogs.
Tree frog eggs usually grow for 6 days before hatching．If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.
If hatching early helps protect red—eyed tree frogs from snakes，you might wonder why their eggs don’t always hatch sooner．It turns out that hatching early brings its own danger．Once tadpoles land in the water，hungry fish and other animals like to eat them too．Staying in their eggs for a full 6 days，then，allows frog embryos（胚胎）to grow big and strong．This extra growth improves their chances of surviving in the water．
