I had the meanest mother in the world. While other kids ate candy for breakfast，I had to have cereal，eggs and toast. Others had cokes and candy for lunch，while we had to eat a sandwich. As you can guess，my supper was different than the other kids’. But at least I was not alone in my suffering. My sister and two brothers had the same mean mother as I did.
My mother insisted on knowing where we were at all times. She had to know who our friends were and what we were doing. We had to wear clean clothes every day. Other kids always wore their clothes for days. We reached the height of disgrace because she made our clothes herself，just to save money.
The worst is yet to come. We had to be in bed by 9:00 each night and up at 7:45 the next morning. So while my friends slept，my mother actually had the courage to break Child Labor Law. She made us work. I believed she lay awake all night thinking up mean things to do to us. Through the years，our friends’ report cards had beautiful colors on them, black for passing，red for failing. My mother, however，would merely be content with black marks. None of us was allowed the pleasure of being a dropout.
She forced us to grow up into educated and honest adults. Using this as a background，I’m now trying to bring up my three children. I’m filled with pride when my children think I am mean because now I thank God every day for giving me the meanest mother in the world.

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!
Casey Neistat fihned everything in the experiment with the purpose of.

A．proving that he was not the thief

B．telling people that bike theft was immoral

C．finding out who had a sense of right and wrong

D．making his experiment well-known to the public

We can infer from the third paragraph that morality.

A．can partly explain a selfish urban society

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

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

C．evidence that city life can be really dangerous

D．an example to show team spirit connecting city people

As can be inferred from the passage, the writer probably.

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

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.
Professor DeBolt went on a study trip to rural areas of developing countries to.

A．help farmers make full use of waste

B．seek certain materials to make electricity

C．persuade farmers to grow more coconuts

D．find a suitable place to carry out the experiment

DeBolt thought it was not a good idea to grow fuel crops because.

A．there are plenty of coconuts

B．local farmers have no interest in it

C．it would make food problems worse

D．fuel crop has little use for local farmers

The last two paragraphs mainly tell us that coconut power.

A．needs further experiments and efforts

B．can help solve energy problem perfectly

C．will cause technique and money problems

D．has drawn Indonesia's government attention

What might be the best title for the passage?

A．Make Full Use Of Coconuts	B．Make Power From Coconuts
C．A Perfect Solution	D．Food And Energy Problems

Some expressions in English can be really puzzling. Have a look at the following to see how it challenges your brainpower.
Homeric laughter
The "Homer" in this expression is the Greek poet. People laugh differently. Some laugh silently, while others tend to laugh loudly. "Homeric laughter" refers to laughter of the latter kind. It is at times uncontrollable, and the entire body shakes during the process. This kind of laughter is called Homeric laughter because this is how the gods laughed in Homer's classics.
A three-ring circus
When you refer to a situation as being a three-ring circus, you are saying that it is a situation of complete confusion. There are so many activities taking place all together that they leave you confused or annoyed. The expression comes from the world of entertainment — the circus. The area where the artists perform their acts is called the "ring". In the past, some of the circuses were so grand that they had three acts taking place simultaneously in three different "rings". The audience had to decide which "ring" they wanted to focus on.
In the swim (of things)
When someone is in the swim of things, the individual is actively participating in the things happening around him, as in "I've been ill, but soon I’ll be back in the swim of thing." In the world of fishing, fishermen use the word "swim" to refer to the section of the lake/river where fish can be found in plenty. So, if you are a fisherman and wish to catch a lot offish, where would you be? You would be "in the swim".
Chickens have come home to roost
The word "roost" refers to the place where birds rest. It could be anything — the branch of a tree, a henhouse, etc. The expression is normally used to mean that the bad things that someone did in the past have come back to bite or upset the individual. In other words, one has to face the consequences of the deeds done in the past. The original form of this 700-year-old expression was "curses are like chickens; they always come home to roost".
Which of the following can best describe the picture?

A．Homeric laughter	B．A three-ring circus
