2 . One day a man found a cocoon(茧) of a butterfly in the forest. He sat there for several hours and watched the butterfly. Suddenly a small opening appeared, and the butterfly struggled to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could go no further. So the man decided to help the butterfly.
He took a pair of scissors and cut off the remaining bit of the cocoon so that the butterfly could come out easily. Much to his surprise, the butterfly got a swollen body but very small, weak wings when it came out of the cocoon.
The man continued to watch the butterfly because he expected that the body would grow smaller at any moment and the wings would enlarge and be able to support the body. But neither happened! In fact, the butterfly spent the rest of its life crawling around with a swollen body and small wings. It was never able to fly.
The man was in his kindness, but he did not understand the nature rules. The struggle required for the butterfly to get through the tiny opening was God's way of forcing fluid (流体) from the body of the butterfly into its wings so that it would be ready for flight once it achieved its freedom from the cocoon.
Sometimes struggles are exactly what we need in our life. If God allowed us to go through our life without any difficulties, it would make us fail. We would not be as strong as we could have been. And we could never fly.

3 . Though cell-phones are usually considered devices that connect people, they may make users less socially minded, which is found by a recent study from the University of Maryland’s Robert H. Smith School of Business.
Marketing professors Anastasiya Pocheptsova and Rosellina Ferraro, with graduate student, Ajay T.Abraham, conducted a series of experiments on test groups of cellphone users. The findings appear in their working paper, The Effect of Mobile Phone Use on Prosocial Behavior. Prosocial behavior, as defined in their report, is action intended to benefit another person or society as a whole.
The researchers found that after a short period of cellphone use the subjects were less likely to volunteer for a community service activity, compared to the control-group（对照组）. The cell phone users were also less persistent in solving word problems even though they knew their answers would contribute to a monetary（货币的）donation to charity.
The study involved separate groups of college student subjects - both men and women and generally in their early 20s. "We would expect similar effects with people from other age groups," said Ferraro. "Considering the popularity of cellphones, it does have the potential to have wide social effects."
The researchers use previous research to explain the cause of their findings: "The cellphone directly arouses feelings of connection with others, thus fulfilling the basic social need to belong." This results in reducing one’s desire to connect with others face-to-face or to engage in empathic (同情的) and prosocial behavior.
The study also distinguished its subjects from users of other social media — Facebook users — in one of the tests. The researchers found that participants felt more connected to others because of their cell-phones than because of their Facebook accounts, suggesting that this difference in connectedness was the underlying cause of the observed phenomenon.

4 . A strict vegetarian is a person who never in his life eats anything derived from animals. The main objection to vegetarianism on a long-term basis is the difficulty of getting enough protein, the body building elements in food. If you have ever been without meat or animal foods for some days or weeds (say, for religious reasons) you will have noticed that you tend to get physically rather weak. You are glad when the fast is over and you get your reward of a succulent meat meal.
Proteins are built up from approximately twenty food elements called “amino-acids”, which are found more abundantly in animal protein than in vegetable protein. This means you have to eat a great deal more vegetable than animal food in order to get enough of these amino-acids. A great deal of the vegetable food goes to waste in this process and from the physiological point of view there is not much to be said in favor of life-long vegetarianism.
The economic side of the question, though, must be considered. Vegetable food is much cheaper than animal food. However, since only a small proportion of tae vegetable protein is useful for body-building purposes, a consistent vegetarian, if he is to gain the necessary 70 grams of protein a day, has to consume a greater bulk of food than his digestive organs can comfortably deal with. In fairness, though, it must be pointed out that vegetarians claim they need far less than 70 grams of protein a day.
Whether or not vegetarianism should be advocated for adults, it is definitely unsatisfactory for growing children, who need more protein than they can get from vegetable sources.
A lacto-vegetarian diet, which includes milk and milk products such as cheese, can, however, be satisfactory as long as enough milk and milk products are consumed.
Meat and cheese are the best sources of usable digestible and next come milk, fish and eggs. Slow and careful cooking of meat makes it more digestible and assists in the breaking down of the protein content by the body. When cooking vegetables, however, the vitamins, and in particular the water-soluble vitamin C, should be lost through overcooking.

5 . You are given many opportunities in life to choose to be a victim or creator. When you choose to be a victim, the world is a cold and difficult place. “They” did things to you which caused all of your pain and suffering. “They” are wrong and bad, and life is terrible as long as “they” are around. Or you may blame yourself for all your problems, thus internalizing your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others.
Those who choose to be creators look at life quite differently. They know there are people who might like to control their lives, but they don't let this get in the way. They know they have their weaknesses, yet they don't blame themselves when they fail. Whatever happens, they have a choice in the matter. They believe their dance with each sacred moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.
Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims plunge themselves into anger, guilt, and other emotions that cause others -and even themselves-to feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. Both victims and creators always have a choice to determine the direction of their lives.
In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. Another with the same experience may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.
In every moment and every circumstance, you can choose to have fuller, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are.

7 . When I travel the country speaking to high school and college students about exactly what they need to do to become financially successful in life, I always begin my presentation by asking three questions:
“How many want to be financially successful in life?”
“How many think they will be financially successful in life?”
Almost every time I ask the first two questions every hand rises in the air. Then I ask the magic third question:
“How many have taken a course in school on how to be financially successful in life?”
Not one hand rises in the air, ever. Clearly every student wants to be successful and thinks they will be successful but none have been taught by their parents or their school system how to be financially successful in life. Not only are there no courses on basic financial success principles but there are no structured courses teaching basic financial literacy. We are raising our children to be financially illiterate and to fail in life. Is it any wonder that most Americans live paycheck to paycheck? That most Americans accumulate more debt than assets? That many Americans lose their homes when they lose their job? Is it any wonder that most Americans cannot afford college for their children and that student loan debt is now the largest type of consumer debt?
What's worse is what our children are being taught by their parents, the school system, politicians and the media. They are teaching our children that the wealthy are corrupt, greedy, have too much wealth and that this wealth needs to be redistributed. What kind of a message do you think that sends to America's future generation? It is teaching them that seeking financial success by pursuing the American Dreams is a bad thing.
The statistics from my five-year study on the daily habits that separate the wealthy from the poor illustrate the fact that the poor are poor because they have too many Poverty Habits and too few Rich Habits. Poor parents teach their children the Poverty Habits and wealthy parents teach their children the Rich Habits. We don't have a wealth gap in this country, we have a parent gap. We don't have income inequality, we have parent inequality.
Parents and our schools need to work together to instill good daily success habits as follows:
•Limit T. V., social media and cell phone use to no more than one hour a day.
• Require that children read one to two educational books a month.
• Require that children set monthly, annual and 5-year goals.
• Require that children save at least 25% of their earnings or gifts they receive.
• Teach children the importance of relationship building by requiring them to call friends, family, teachers, coaches etc. on their birthdays and to send thank you cards for gifts or help they received from anyone.
• Reassure children that mistakes are good not bad.
• Children need to learn how to manage money.
• Teach children how to manage their time.
1. What's the writer's purpose of raising the three questions at the beginning of the presentation?| A．To show children's ambition to lead a successful life. |
| B．To attach importance to financial success. |
| C．To blame parents, teachers, and the media for the lack of courses about money management. |
| D．To emphasize the association between financial success and financial literacy. |
| A．Get used to. | B．Increase. | C．Pay back. | D．Borrow. |
| A．Parents open up a checking account or savings account for children and force them to use their savings to buy the things they want. |
| B．Children understand that the very foundation of success in life is built on learning from parents' mistakes. |
| C．Children spend no more than 1 hour per day on Internet use. |
| D．Children are required to create daily “to do” lists and these lists are monitored by parents. |
8 . One of the major problems in our economy is inflation, a situation in which prices are going up faster than wages. Thus, a person has to work more hours to pay for the same items.
For example, let's say that this year a loaf of bread costs S1. 00 and the average salary in the United States is $10. 00 per hour. That means a person could earn enough money to buy a loaf of bread in one-tenth of an hour, or six minutes. Then, halfway through the year, the price of the bread goes up to $1.25, while wages stay the same.
That means that a person now has to work one-eighth of an hour-seven and a half minutes-to buy the same loaf of bread.
Now let's say that at the end of the year, wages go up to $11. 00 per hour, but the price of bread goes up to $1.50. Now a person has to work more than one-seventh of an hour-over eight minutes -to buy the same loaf of bread. As you can see, if more and more work time is spent earning money to buy loaves of bread, employees will have less money left over to buy other things. Inflation means that the same money buys fewer things, and everybody's standard of living goes down, even if salaries are going up.
Some kinds of inflation are worse than others. Moderate inflation does not distort relative prices or incomes severely. Galloping inflation happens rapidly, say at a rate of 100 percent or more within a year. And then there is hyperinflation-inflation so severe that people try to get rid of their currency before prices rise further and render the money worthless. Times of hyperinflation are usually characterized by social and political disorder.

10 . High-quality customer service is preached(宣扬)by many,but actually keeping customers happy is easier said than done.
Shoppers seldom complain to the manager or owner of a retail store,but instead will alert their friends,relatives,co-workers,strangers-and anyone who will listen.
Store managers are often the last to hear complaints,and often find out only when their regular customers decide to frequent their competitors,according to a study jointly conducted by Verde Group and Wharton School.
“Storytelling hurts retailers and entertains customers,” said Paula Courtney,President of the Verde Group. “The store loses the customers,but the shopper must also find a replacement.”
On average,every unhappy customer will complain to at-least four others,and will no longer visit the specific store. For every dissatisfied customer,a store will lose up to three more due to negative reviews. The resulting “snowball effect” can be disastrous to retailers.
According to the research,shoppers who purchased clothing encountered the most problems. Ranked second and third were grocery and electronics customers.
The most common complaints include filled parking lots,cluttered(塞满了的)shelves,overloaded racks,out-of-stock items,long check-out lines,and rude salespeople.
During peak shopping hours,some retailers solved the parking problems by getting moonlighting(业余兼职的)local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly,and avoided confrontation between those eyeing the same parking space.
Retailers can relieve the headaches by redesigning store layouts,pre-stocking sales items,hiring speedy and experienced cashiers,and having sales representatives on hand to answer questions.
Most importantly,salespeople should be diplomatic and polite with angry customers.
“Retailers who're responsive and friendly are more likely to smooth over issues than those who aren't so friendly,” said Professor Stephen Hoch. “Maybe something as simple as a greeter at the store entrance would help.”
Customers can also improve future shopping experiences by filing complaints to the retailer,instead of complaining to the rest of the world. Retailers are hard-pressed to improve when they have no idea what is wrong.
