| When I was a teenager growing up in France, I wanted to leave school and have my own life. The only way I could do this was to work in the local paper factory in my town, or get married. I was very nervous then I told my 1 I wanted to leave school. I thought he would say, " 2 ! You are going to college." I was very 3 when he said, "OK. Let's go to the paper factory." Two days later, he took me to the factory. I imagined everyone to be friends 4 together and having fun. I even imagined there would be music and singing. I guess I had watched too many movies as a teenager. When we 5 the factory gate, my father spoke to the guard and one minute later we were 6 . I walked around the factory looking at the building, the workers, and listening to the noise. It was 7 . I ran back to my father and said, "I want to go home." He asked me,"What do you think of the factory?" "Too bad," I answered. "And marriage is even 8 !" he said. I went back to school the next day thinking about studying hard 9 I could get into a good college. I 10 studying English, so I decided to major in languages at college. Thanks to my father and our trip to the paper factory, I now work at the United Nations and my father is very proud of me. I married a very good man and my life is much better than it would have been working in the factory! | ||||

City officials are hoping to use the power of dog droppings. San Franciscans already recycle more than 60% of their dogs’ droppings, but in this dog-friendly town, such wastes make up nearly 4% of residential waste, or 6,500 tons a year.
Within the next few months, Norcal Waste, a company that collects San Francisco’s wastes, will begin a trial program under which it uses biodegradable (生物分解的) bags and dog-waste carts to pick up droppings at a popular dog park.
The droppings will be thrown into a machine called a methane digester (沼气处理机), which is basically a tank in which bacteria feed on droppings for weeks to create methane gas.
The methane could then be piped directly to a gas stove, a steam heater, an air turbine or anything else powered by natural gas. It can also be used to produce electricity.
Someone doubts whether this plan is practical. But Norcal Waste spokesman, Robert Reed points to San Francisco’s creative food composting (混合肥料) program, which began 10 years ago. It is a proof that an unusual idea can work in this forward-thinking city. Norcal Waste collects 300 tons of food left over after meals per day from homes and restaurants and changes it into a rich fertilizer sold to grape farms and organic farms.
Methane digesters are nothing new. The technology was introduced in Europe about 20 years ago, and more than 600 farm-based digesters are in operation there. Nine are in use on California cow farms, and chicken and pig farms elsewhere in the United States also use them.
“The main obstacle is probably getting communities around the country the courage to collect dog droppings, to give value to something we’d rather not talk about,” Brinton, a recycling and composting consultant, said. “San Francisco is probably the king of pet cities. This could be an advantage of it, which is very important.”
Some other experts believe energy production from dog droppings must become more attractive economically before it gets popular. Landfill space is relatively cheap, and natural gas and electricity also remain fairly inexpensive. However, Reed said confidently, “Now, the city authorities asked us to look at dog waste specifically.”
