Once a boy came to ask a fisherman how to become cleverer, because his mother always called him “foolish boy”.

    “That's easy,” answered the fisherman. “I know one way to make you become cleverer.”

    “Really?”

    “Of course. It is said a fish head is good for brain. If you eat one, you'll become cleverer indeed. Pay only three pounds for one fish head.” The boy paid him three pounds and the fisherman cut off a fish head and handed it to him.

    A raw fish head is not good—not even for a hungry boy to eat but the boy ate it up in  two gulps.

    “Do you feel anything?” asked the fisherman.

    “Not in my head,” said the boy.

    The boy lay on the ground and thought. “One whole fish costs only two pounds. I have paid him three pounds for the fish head. Why couldn't I have the whole fish for soup, a head for brain and one pound left over?” He jumped up and shouted at the fisherman. “You thief! You are fooling me!” The fisherman laughed, saying, “The fish head works now, you see.”

    Business administration is the most popular undergraduate major in U.S. colleges and universities, accounting for as much as one-fifth of all bachelor degrees awarded each year. Students naturally think of a business degree as the surest way to land a good job after graduation. Many international students agree. Twenty percent studied business last year-the second most popular major after engineering, according to the Institute of International Education.

    Below are descriptions of three of U.S. colleges and universities with strong offerings in business.

    Bentley College    Waltham, Massachusetts

    Bentley offers its 4,000 undergraduates a top-flight business education and an equally strong liberal-arts program that leaves them well-prepared to join the ranks of future business leaders. The college occupies a scenic campus only a shuttle-bus ride from Boston's Harvard Square. More than 90 percent of students seek career-oriented internships（实习）.

    Bucknell University    Lewisburg, Pennsylvania

    Bucknell's 3,500 undergraduates benefit from small classes and an engaging staff at this liberal-arts institution in a remote but beautiful campus in central Pennsylvania. Accounting and financial management are specialties in the introductory management course that create and sell a product and then donate their profits to charity（慈善）.

    University of Cincinnati        Cincinnati, Ohio

    This urban university with 21,000 undergraduates, located a mile from downtown Cincinnati, was the-birthplace of cooperative education over a century ago. Under this five-year “earn while you learn” program, more than 3,000 students alternate academic study with internships in local businesses and other organizations.

    The discussion on renewable energy has been going on for at least a decade and people have relied on fossil fuels almost entirely for more than a century. However, the situation when fossil fuels were the most efficient and the cheapest source of energy has been left far in the past. Many countries such as Germany and Sweden have already made significant efforts to fix this situation, employing numerous power plants working on the renewable resources of energy. The most effective among these resources is geothermal（地热的）energy.

    Geothermal energy does not depend on the world's economic and political situation as strongly as fossil fuels do. Besides, extracting（提炼）fossil fuels adds to the price of energy produced from them. Therefore, geothermal energy is much cheaper than traditional ones, saving up to 80% of the costs over fossil fuels.

    Being a renewable resource, geothermal energy produces less waste and pollution than traditional energy sources. In geothermal systems, carbon dioxide makes up about 10% of air produced. Overall, in order to produce the electricity that can be used for one hour, the geothermal systems produce 0.1 pound of carbon dioxide and other harmful gases. For a comparison, a power plant producing from gas produces up to 2 pounds of carbon dioxide into the atmosphere, and those power plants that work on coal（煤）produce an astonishing 3.6 pounds of greenhouse gases.

    Low costs is another reason why using geothermal power plants should be the first choice for many countries. Geothermal heat systems require 25% to 50% less energy for work compared with the traditional systems for heating or cooling. Besides, geothermal equipment is less big: due to the very nature of geothermal energy, geothermal power plants have only a few moving parts, all of which can be easily sheltered inside a relatively small building. What's more, the life span of geothermal equipment is rather long. All these make geothermal power stations easy to build and keep.

    Grandparents Answer a Call

    As a third-generation native of Brownsville, Texas, Mildred Garza never planned to move away. Even when her daughter and son asked her to move to San Antonio to help with their children, she politely refused. Only after a year of friendly discussion did Ms. Garza finally say yes. That was four years ago. Today all three generations regard the move as a success, giving them a closer relationship than they would have had in separate cities.

    No statistics show the number of grandparents like Garza who are moving closer to adult children and grandchildren. Yet there is evidence (证据) suggesting that the trend (趋势) is growing. Even President Obama's mother-in-law, Marian Robinson, has agreed to leave Chicago and move into the White House to help care for her granddaughters. According to a study by grandparents.com, 83 percent of the people said Mrs. Robinson's decision will influence grandparents in the American family. Two-thirds believe more families will follow the example of Obama's family.

    “In the 1960s we were all a little wild and couldn't get away from home far enough or fast enough to prove we could do it on our own,” says Christine Crosby, publisher of Grand, a magazine for grandparents. “We now realize how important family is and how important it is to be near them, especially when you're raising children.”

    Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices (牺牲), but sometimes it is wiser to say no and visit frequently instead. Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.

    Nine years ago, a few days before Christmas, I was a director at a company in San Francisco, and I was called into a meeting that was already in progress. That meeting turned out to be my exit interview. I was 64 years old at the time. It wasn't completely unexpected. I signed a pile of papers and left the company.

    So, 40 plus years of employment was over. I had a good reputation and background. Retirement was not a choice for me. I wanted to do something. And then an idea came into my mind, born from my concern for our environment. I wanted to build my own business, designing and producing biodegradable(可生物降解的)packaging from waste. This is called clean technology, and it was really meaningful to me. It could help reduce billions of pounds of single-use plastic packaging wasted each year.

    Five years later, I'm delighted and proud to share with you that our income has doubled every year and we have no debt. Meanwhile, I have a wonderful partner, and we've won more than 20 awards for the work that we've done.

    And I am doing the most rewarding and meaningful work of my life right now. But what I really long for is to find other first-time entrepreneurs(企业家)who are my age. I want to connect with them.

    So I want to do something about that in a few years. I want us to start talking more about people who don't become entrepreneurs until they are seniors. And then connecting all of them across industries, regions and countries—building a community.

    The San Francisco Giants added a special pitcher(投球手)for the day. It was small—yet fierce—Hailey Dawson, who has a 3D-printed hand.

    The energetic 8-year-old from Nevada was invited to throw out the first pitch at the Giants game on Sunday. Dawson was born with Poland syndrome(综合症), a disorder in which affected individuals are born with missing or underdeveloped muscles on one side of the body. It affected her hand.

    With a traditional prosthetic(假肢)potentially costing thousands of dollars, Hailey's mom, Yong Dawson turned to the University of Nevada, Las Vegas for help. She emailed UNLV engineering, and they accepted the challenge. Brendan O'Toole, chairman of the mechanical engineering department, said he and his team had got a lot of requests, "but this one was different." They got to work using a 3D-printer.Several prototypes(原型)and fittings later, Dawson got her first hand about four years ago.

    Hailey's mother said the hand had given her daughter a wonderful lift. "When she puts this robotic hand on, it changes her personality and confidence level," Yong Dawson told CBS San Francisco. "I love seeing that. I just wanted her to have an even playing field."

    When she arrived at AT&T Park on Sunday, Hailey got to hang out with players in the shelter at the side of the sports field. They even let her try on their World Series rings.

    Using her 3D-printed hand, Dawson threw out the perfect first pitch. Then with a wave and a smile, she headed into the stands to cheer on her newfound friends on the Giants.
