I truly thought thatI might die that day. Had I not seen three bears and a few wolves over the last couple of days near the road, I might have just lain down and called it quits. What in the world was I thinking, dragging my bike up to Yellowstone and thinking I could ride from West Yellowstone to Old Faithful in the snow? No less!

I had planned this trip for more than two months, and I wasn't about to give up so easily. The first few miles were beautiful. Ten miles in, I started sucking wind. Fifteen miles and my legs felt like they were made of lead. By twenty miles, my lungs were burning and felt like there was nothing left in the tank. That was when I turned around and saw my husband and three children cheering me on in the van behind me. I knew I couldn't quit because I tell my children all the time that just because something is hard doesn't mean that you stop doing it. I had to live what I'd been preaching(说教). That thought got me up that mountain and to the end of the ride.

The importance of that ride was apparent after only a week. My eight-year-old daughter Emalee wanted to ride in a twelve-mile charity ride. That day was cold as well. She was the youngest rider. About four miles into the ride, she started feeling cold. The chill(寒冷)was making her muscles cramp a little and she began to struggle. By six miles, she had tears running down her face. It broke my heart to see her suffering like that.I told herthat she didn't have to finish. She said that she wouldn't quit. I told her how I had wanted to quit the week before, but perseverance had gotten me to the end and I knew she could do it, too.

The look on her face as she pulled into the finish was priceless. She threw her arms around me and said, “You didn't quit, Mommy, so neither did I.”

As every mobile-phone owner knows, after a year or so the battery starts to fade and the beast needs recharging more frequently.That is troublesome, but a phone’s batteries can be replaced fairly cheaply — or the whole device traded in for the latest model. An electric car, though, is a much bigger investment. And batteries are its priciest component, representing around 30% of an average mid-size vehicle.

To provide buyers with some peace of mind, carmakers guarantee their batteries, typically for eight years or around 200,000km. Producers, planning to go much further than that, though, are racing to launch “million mile”

(1.6m kilometers) batteries. Contemporary Amperex Technology, a giant Chinese firm which produces batteries for

a number of carmakers, was said to be ready to start producing batteries which would last for 16 years or 2m kilometres. Elon Musk has suggested that Tesla,a Californian maker of electric vehicles, has a million-mile battery in the works. And over in Detroit,General Motors is in the final stages of developing an advanced battery which it says has similar longevity (寿命)。

Regular fast-charging reduces battery life, as do overcharging and deep discharging. Driving in extremely hot or cold weather does not help either. And battery life will diminish even if you just leave the car in the garage. The real point of a million-mile battery is that the technological advances required to make it possible will deal with these things as well.

Battery technology is improving all the time, and by no means are million-mile batteries the limit of engineers’ ambition. The next objective is to replace Li-ions’ liquid electrolytes (电解质) with solid ones. That would allow even longer driving ranges, which could make a two-million-mile battery an achievable objective. If that day comes,the tables would have been turned. From being the first part of a car to fail, its battery will have become the last.

4. The battery problem of mobile phones is mentioned to_____.
