When baby turtles first come out of eggs, they head to the sea by nature. The beach surface goes down, which is one directional clue they follow. Another is light: The horizon (地平线) over the sea is brighter than the horizon over land.
But lights from towns and beach developments can confuse the baby turtles. The sky shining above a city can mislead them to wander. And particularly bright lights can draw them away from the sea.
You’d think the extra time crawling (爬行) might wear out baby turtles, which need energy once they get in the water to swim for about a day to get to their destination in the sea. In a normal trip from nests to waves, the babies build up chemicals that show they have been pushing themselves.
Some researchers took the baby turtles to a lab, where they ran on a treadmill and swam in a tank while their blood and breathing were monitored. The finding is surprising: even after hours of crawling, the turtles were fine by all measures and swam as well as turtles that didn't have an extra crawling period.
The reason is that they often stop while crawling if they are doing U for a long time, unlike the disturbed trip they make when heading straight to the water. So misled turtles are not worn out.
But the misleading lights are still a problem for the babies. The longer they spend on the beach wandering, the more they are exposed to natural enemies. They can also end up losing their lives in the heat of the sun.

The bus screamed to a stop in Nazareth, Israel. Five Australian backpackers boarded and struck up a conversation with me. They asked typical travelers’ questions—where was I going and why was I traveling alone? My plan was to travel with a friend of a friend, I explained, but when I called her that morning, she didn’t pick up and I had no other way to reach her. My stomach was in knots, but I decided to head out anyway, thinking I might run into her if I traveled to Tiberius, where we had planned to go together.
“Why don’t you travel with us?” one of the backpackers offered. They were experienced adventurers who would work for a few months, save, then travel for as long as they could. Their current plan was to explore the Middle East and Europe in three months while working in London.
It seemed risky to travel with strangers, but my instinct said yes. For the next two weeks, I explored Israel with the backpackers and learned to trust my instincts in all types of new and interesting situations. When they hook a ride, I took the bus, but when they wanted to steal into the King David Hotel’s swimming pool, I led the way. The world opened up to me because I chose to travel alone. I joined complete strangers, who become close friends. Years later, one couple from the backpacking group even flew from Sydney to Phoenix to be in my wedding. The trip was such a special experience that it gave me confidence in all areas of my life. Since then, I’ve backpacked alone across South Africa, sky-dived from 12,000 feet in New Zealand and even moved across the U.S. with no job lined up.
On my third day wandering in Israel with my new friends, I bumped into the woman I was supposed to meet. Though I was happy she was all right, I was grateful she hadn’t picked up the phone.

There was something in the elderly woman’s grace that caught my eye. Although slow and unsure of her steps, the woman moved with deliberation (从容), and there was no hesitation in her gestures.
It was a few years ago, and I had taken a part - time holiday - season job in a video. store at the local shopping mall. From inside the store, I could see the people outside rushing by.
The elderly woman entered the store, along with her daughter, who was displaying a serious case of impatience, rolling her eyes, sighing and checking her watch every few seconds. I guessed if she had possessed a rope, she would have fastened it to her mother to drag her along to keep step with the rush of other shoppers.
The elderly woman separated from her daughter and began to seek through the DVDs on the nearest shelf. After the slightest hesitation, I walked over and asked if I could help her find something. The woman smiled up at me and showed me a title written on an old piece of paper.
Rather than rush off to locate the DVD for the woman, I asked her to walk with me so I could show her where she could find it. Looking back, I thought I wanted to enjoy her company for a moment.
Something about her deliberate movements reminded me of my own mother, who’d passed away the previous Christmas. I missed my mom and still felt regretful about the moments when I’d used my impatience to make her life unhappy.
As we walked along the back of the store, I introduced its floor plan: old television shows, action movies, cartoons, science fiction. The woman seemed glad of the unrushed company and casual conversation.
We found the DVD and she thanked me, saying that it was the one she’d enjoyed when she was her daughter’s age. Unwillingly, I accompanied her to the cash register, realizing I had to return the elderly woman to her daughter, who was still tapping her foot at the front of the store.
Paragraph 1: As the elderly woman was waiting in the queue at the cash register, I walked over to her daughter. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2: Together they made their way toward the store’s exit. _________________________________________________________________________________________________________________________________________________________________________________________________________________________
