How would you use a radio or a telephone if you had no electricity or batteries? These1bothered (使烦恼) British inventor Trevor Baylis. So in 1996 he2a wind-up (装有发条的) radio. It doesn't need electricity or batteries. You wind it up3hand. It plays for about an hour. Then, you wind it up4.

    Baylis also invented a mobile phone that is powered by5. The shoes contain (含有) a small battery that is powered when you6. This battery is connected to a mobile phone. These two simple inventions can bring modern7to all parts of the world.

    Baylis didn't have a university degree in engineering. In8, he left high school before graduating (毕业). He just loved9things to help people. He never knew10ideas would come to him. The idea for the phone came to him in a dream.

    A girl went to her father and told him that her life was too hard. She said she couldn't work all the difficulties out 1. She just wanted to give up.

Her father said, "I think I know 2 I can help you. 3 me." They went into the 4. Her father put a potato, an egg and some coffee beans into three different bowls of water. Then, he started to boil (煮沸) the water on the stove.

After some time, he turned the stove 5 and took out the potato, the egg and the beans. He then showed each of them to his daughter.

"Look. The potato was hard before I boiled it, but now, it is 6 and weak. The egg was fragile (易碎的) until I put it in the water—now, it is hard inside. But the coffee beans were different. When they met the boiling water, they changed and became delicious 7."

Life 8 problems to us all. The potato, egg and coffee beans were all met with the same problem. But they each solve the problem in their own way. It is up to you to take the difficulties you face and find something good in 9. By making a(n) 10, the father taught his daughter a life lesson.

One Thursday afternoon, when I was in Grade 7, a new boy came into my classroom. He was short and thin. He walked up to the teacher and told her, very seriously, that he was new. His name was Christian. He sat down, took a look at me, and then looked away. I didn't think he was very nice and I was sure he wasn't the type I would like to become friends with.

During that year, I didn't talk to him much, but he smiled at me when our eyes met, always shyly. He never ate lunch with anybody, and he never talked to anybody but me.

But one day I joined those unkind kids who were making fun of him. We made fun of him though I thought it was wrong. 

"Haven't you got any friends? " a kid asked Christian, who had walked past us alone, head down.  "No, he hasn't got any friends. He's too stupid and shy. " I said. Then Christian looked up at me with the saddest dog eyes I had ever seen. I felt very sorry at that moment.

That night, I couldn't sleep because I couldn't get Christian's face out of my mind. In the weeks that followed, he never met my eyes in class and never smiled at me. It was really hard for me to decide to write him a note asking him to forgive（原谅）me. But I thought I should. 

The next day in class, I wrote him a note telling him how sorry I felt. About five minutes later, I turned and saw tears in his eyes. "You will never realize (意识到) what your apology（道歉）has meant to me, Jimmy, "he said to me. "I hope we can become friends. "

We had lunch together that noon and we had the best talk I had ever had. Over the years at high school, we were close friends.

When I think back, I realize that, if I had not apologized, I would never have known what a lovely person Christian was.

Apologies can really change your life, so never miss the chance to tell somebody you are sorry.

Question 1: How did you become a National Geographic photographer?

My first job was for a newspaper. After a few years there, I met a National Geographic photographer. He liked my photos and said I should send some to the magazine. So I did. That led to a one—day job. And that led to a nine—day job, and so on. 

Question 2:     ▲    

To get into National Geographic, you have to give them something they don't have. It's not enough just to be a great photographer. You also have to be a scientist, for example, or be able to dive under sea ice, or spend maybe several days in a tree. 

Question 3: Is it hard to get a job as a photographer today?

It's now harder to work for magazines. Technology makes it easy to take good pictures, which means there are more photos and photographers. Also, the Web is filled with photos from all around the world that are free, or cost very little. These photos are often good enough to be put in books and magazines. What the magazines need to do these days is to pay for these photos. 

Question 4: I want to be a photographer. Do you have any advice for me?

Advice? Well, work hard. Be passionate (热情的)about every project you work on. Take lots of pictures in different situations. Look at others' photos thoughtfully and learn from them. And be curious about everything. There's something to photograph everywhere. 

The other day, my husband called me to the balcony(阳台). "Come, dear, look at that car!" 

"What's up?" I asked, looking down at the square in front of our apartment building. A driver was trying to park between two cars. 

"That must be a woman," my husband said.

"How do you know?"

"I've watched the car move back and forth twenty times. Men can't be so bad at driving!"

"What if the driver is a man?" I asked.

"I bet you 50 yuan that the driver is a woman!"

We stood on the balcony and watched the car. It felt a little silly. Five minutes later, the car was finally parked perfectly, and a man slowly got out.

"Fifty yuan please," I said to my husband as he silently walked away.

My husband is not alone in looking down on female drivers. On weekends, my friend Lily likes traveling around the city by bus. But she always hesitates to get on a bus if the driver is a woman. "I can't trust a female driver," she told me one day. "Women are not born to drive, you know."

"Sorry, but I don't know," I said. I go to work by bus every day, and I never think female drivers are any worse. In fact, they are often more careful than men. Research also shows that female drivers are 8.8 times less likely to cause accidents than male drivers.

There are not many female bus drivers, though. And in the history of Formula One(一级方程式赛车), only 0.26 percent of drivers have been women. Without role models, many girls may think they are not meant to be good drivers. But the ability to drive has nothing to do with gender. Women can drive well, too. It's time to stop making jokes about female drivers.
