Seth DeBolt is a plant scientist at the University of Kentucky US. He and other scientists wanted to find a source of fuel that poor people in rural areas of developing countries could use to make electricity.

The United Nations Development Program says a billion and a half people have no electricity. A billion others have an undependable supply.

    Professor DeBolt went on a study trip to rural Indonesia. He saw that there was very little waste in the use of agricultural products. Everything that farmers grew was used for something. Even the remains of fruit that people did not eat were fed to chickens.

Little waste meant there was little that could be used for fuel. Growing a separate fuel crop would take land away from food crops. That was something Professor DeBolt did not want to do.

    DeBOLT said, "The people at most risk with respect to energy poverty, typically they're the same people who have food insecurity issues as it is. And then any change in availability would be most damaging to that group of people."

    But he found one item that was in plentiful supply and would not create competition between food and fuel. Coconut shells are generally thrown out. Yet Professor DeBolt says it has an "excellent" heating value. All someone needs is a way to release that energy.

    DeBolt says he and his team see possibilities for coconut power. "Coconuts are growing here and these are the areas where there is possibility for energy poverty to be eased at least in part by these small-scale production systems."

    The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia. Other tropical countries with large crops of coconuts and similar fruit could benefit, as well.

    But DeBolt says this is not a perfect solution. There are technical questions, like how to safely deal with the dangerous waste produced in the process. And there needs to be money to get these projects started.

The city can seem a cold, mean place. In the middle of so many people hurrying about their own business, a person can feel alone among the millions of others.

    There is a popular view that in cities, strangers are less likely to help an elderly person cross a street or call the police when they see a bike being stolen. Recently, a New Yorker named Casey Neistat did an experiment. He chained up his bike in several public places, then "stole" it in a number of obvious ways, such as using a hacksaw (钢锯). He filmed everything to see whether other New Yorkers would try to stop a shameless bike theft. The result? People just walked on by.

    Is this evidence of an immoral, selfish urban society? Not necessarily. According to another recent study, the way city people mind their own business is about other factors besides morality (道德).

This is called the Bystander Effect, the theory that city people do not react because of the urban enviromnent they live in.

Psychologist Dr. Harold explained why people did not involve themselves in Neistat's bike theft experiment with the Bystander Effect.

    First, people who live in cities are surrounded by so much activity that they stop noticing what is going on around them. Second, they are less easy to surprise and assume every activity has a logical explanation.

    "The third is that people notice it, but they don't know what to do," he continued. "And the fourth is fear — they know they should do something, but they're afraid to challenge someone with a hacksaw."

A lack of concern is only a small reason why people don't take action, concludes Dr. Harold.

     Despite the results of Neistat's experiment, there is also evidence of a sense of team spirit that connects people in cities. All it takes is a funny joke or a shared interest to start a conversation with someone at a bus stop. When city folk are in trouble, they come together for support — famously in New York on September 11, 2001.

City society is different, but that doesn't mean it's cold or mean — it just means it's busy!

    B. is what our society should pay special attention to

    C. is the only factor that leads to a selfish urban society

    D. is the root of the Bystander Effect mentioned in the passage

3.The underlined part September 11, 2001 in Paragraph 9 serves as       .

    A. a reminder of the sad memories

    B. a way to prove Dr Harold's Bystander effect

    A. criticizes the loss of morality in urban society

    B. feels sad about the result of Neistat's experiment

    C. thinks city people are too busy to care about others

D. disagrees that city life sometimes can be cold and mean

 

Once upon a time there was a painter who had just finished his course from a great painter. He wanted to assess his skills, so he decided to display one of his best works on a busy street.

    He put his painting at a busy street-crossing. And below it a board read — "Gentlemen, I have painted this piece. Since I'm new, I might have made some mistakes in my work.   65  "

    When he came back in the evening to collect his painting, he was completely shocked to see that the whole painting was filled with crosses.

        66   He burst into tears and said sadly, "I'm useless and if this is what I have learned to

paint, I'm not worth teaching."

    The master smiled and suggested, "My son, I will prove that you are a great artist." The master told him, "Just paint the same painting once again and give it to me."

    Then they went to the same street the next morning and displayed the same painting. The master took out another board which read — "Gentleman, I have painted this piece. Since I'm new, I might have made some mistakes. I have put a box with colors and brushes just below. Please do

me a favor.   67  "The master and the young painter went back home.

     They visited the place in the evening. The young painter was surprised to see that actually there was not a single correction done!   68   If you want to help people improve their behaviors, it is worth investing your effort in learning how to help people change their behaviors, attitudes and skills. Also, always remember not to get carried away or judge yourself by someone else's criticism and feel depressed as you are the best judge to judge yourself!

A. It is easy to criticize, but difficult to improve.

B. Please put a cross wherever you see a mistake.

C. Discouraged and broken, he ran to his master's place.

D. If you see a mistake, kindly pick up the brush and correct it.

E. Criticizing has the function of helping people improve themselves.
