She was stopped in the left hand turn lane (车道), (62) to get onto the highway but never (63) it. I slowed down, rolled open my window and asked. “Do you need any (64) ?”

“Yes, I ran out of gas. I just moved here and I don’t even know (65) a gas station is,” she replied.

She didn’t have a gas can, so I told her I’d run down the (66) to see if I could get one from the local station. When I (67) with a full can of gas, she couldn’t (68) me enough and told me she would pay for the an and gas. (69), I refused.

As I was (70) the gas in, she said, “I thought no one would even stop. I was afraid to leave the car and even more afraid to (71) help.”

“Well, I couldn’t pass by (72) offering help,” I said. “I’ve used up gas myself a few times. You know I’m getting (73). Now I’m running out of gas and time. It just seems to fly by.”

I laughed so hard that I (77) dropped the container. She tried to start the car and it (78). The I told her to keep the (79) can in her trunk.

Seeing her grateful (80), I said friendly, “I’m glad to be of help. Welcome to Pennsylvania.”

For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).

But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.

The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.

Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.

We lived in a very quiet neighborhood. One evening I heard a loud crash in the street. Earlier that evening my wife had asked me to go to the store to get some soft drinks. It seemed like this would be a good time to let my teenage daughter Holly practice her driving, so I sent her to the store in my truck. At dinner my son talked about how much he liked my truck. I enjoyed having it, but I said, "Guy, my heart is not set on that truck. I like it but it is just metal and won't last forever. Never set your heart on anything that won't last." After hearing the loud noise, the whole family ran outside. My son shouted, "Dad! Dad! Holly crashed your truck."

My heart sank and my mind was flooded with conflicting thoughts. Was anyone hurt? Who else was involved? As I ran to the door, I heard a voice in my heart say, "Here is a chance to show Holly what you really love. She'll never forget it."

The accident had occurred in my own driveway. Holly had crashed my truck into our other vehicle, the family van. In her inexperience, she had confused the brakes and the gas pedal (油门). Holly was unhurt physically but when reached her, she was crying and saying, “Oh, Dad, I'm sorry. I know how much you love this truck." I held her in my arms as she cried.

Later that week a friend dropped by and asked what had happened to my truck. I told her the whole story. Her eyes moistened（润湿） and she said, "That happened to me when I was a girl. I borrowed my dad's car and ran into a log that had fallen across the road. I ruined the car. When I got home, my dad knocked me to the ground and began to kick me."

Over 40 years later, she still felt the pain of the night. It was a deep wound on her soul. I remember how sad Holly was on the night she crashed our truck, and how I comforted her. One day, when Holly thinks back on her life, I want her to know that I love her a thousand times more than any piece of property. I repaired the van, but the dent (凹陷） in my truck is still there today. Every day it reminds me of what really matters in my life.

A. The brakes weren't working.

B. Holly stepped on the gas pedal instead of the brakes.
