    My family was gathered for a barbecue when the discussion arose about a celebrity who earned a large amount of money. The major criteria for receiving millions of dollars seem to be determined by how much the audience will pay to watch the performer achieve.

    The discussion led to a sudden self-questioning. Why did I choose teaching for a career? I half-listened to their conversation as I pondered the answer.

    I remembered my three children watching me spend nights planning for my class. I remembered how they intently listened to my frustrations concerning materials, procedures and the amount of responsibility that seemed to endlessly be thrust into the laps of classroom teachers. I remembered when it came time for each of my own children to choose a profession. How I waited to hear if any had plans to follow Mom into teaching. Long considerations held no mention of anyone becoming a teacher.

    Dessert was being served, and everyone was still involved in the discussion of the enormous salary of one individual, when the phone rang. My husband handed the phone to me.

"Hello, this is Bonnie Block," I said.

"Is this the Bonnie Block who used to teach kindergarten?"

    A nervous sensation swelled in me, and my mind raced with memories of those days long ago.

"Yes!" I exclaimed with a lump in my throat. It seemed like forever as I waited anxiously to hear what the caller would say next.

"I am Danielle—Danielle Russ. I was in your kindergarten class."

    Tears of surprise and joy rolled down my flushed cheeks.

"Yes," I uttered softly as I remembered that darling, wonderful child.

"Well, I am graduating from high school this year, and I have been trying to find you. I wanted you to know what a difference you made in my life."

She proceeded to give details. My influence on her wasn't limited to kindergarten but remained a strong motivating force when she needed a coach to help her meet a challenge. "I pictured you praising and encouraging me all the way."

    Why choose teaching?

    The pay is great!

    It is quite natural for all of us to want to preserve and protect the foods we buy. We always think that the best way is by putting them in our refrigerators. However, there are certain foods which should never be placed in the fridge. The foods listed below may surprise you.

    Bananas in the fridge? Because they keep nutrients better outside the fridge, they should never be placed inside the refrigerator. Bananas are better kept on the counter until they ripen. The cold temperatures actually slow down the ripening process of the bananas, while the moisture and darkness of the fridge will only make them go bad.

    Potato should be placed in a cool, dry and dark space. By reason of the cold temperatures of the fridge, it can turn starch（淀粉）into sugar more rapidly. It is also recommended that potatoes be removed from plastic or paper bags they may have been placed in. Also, keep them unwashed, as well as in a well-ventilated cardboard box.

    Placing your onions inside your refrigerator will eventually end up turning them moldy and soft. Unpeeled（未剥皮的）onions should be kept out of plastic bags and fridge. One of the reasons for this is because unpeeled onions require and need air exposure for maximum life. If you have peeled an onion though, then you should keep it in the fridge, in a covered container.

    Believe it or not, placing garlic in your refrigerator will actually cause it to sprout（发芽）. The garlic will also got moldy and even rubbery. Moreover, inside your fridge, the look of the garlic will rarely change. This means you won't be able to tell if it's any good until you finally slice it open.

    Everything has its root. “Holiday”, is no exception. The origin of “holiday” is easy to see, coming from “holy day”, a day of particular religious significance, often celebrating the life of a saint (圣徒), during which no work was to be done. As far back as the 11th century, “holidays”, especially the major feast days, were times of “celebration and amusement”, as the Oxford English Dictionary puts it.

    The number of holidays steadily increased during the Middle Ages, until a medieval Englishman would have had the luxury of 40 to 50 days a year off work, depending on where he lived, in addition to a free day on Sundays.

    During the Reformation, Henry VIII abolished most of the holidays partly because of the Protestant (新教徒的) suspicion of saints, but more practically, because, according to historian Eamon Duffy, “A large number of holidays were making the people poor by limiting agriculture.” The people took a different view and organized a protest march—the Pilgrimage of Grace—partly to protect their days off.

    Though at first the religious and festive senses of holiday were combined, the word gradually came to be used for any kind of relaxing break from work. As the word was drawing away from a religious society, the number of authorized holidays was reduced, until by 1834 most workers had only four official days off a year, in addition to Sundays. Many factory workers amplified this time by staying home on “Saint Monday” to recover from what they had gotten up to the day before.

    By the late 19th century, employers were compromising and offering half-day Saturdays, the beginning of the “weekend”, a term first used in 1879. In 1908, an innovative mill in New England gave its employees all of Saturday off, and the practice of their getting the whole Saturday off spread widely during the Great Depression as a way to keep employment up. It took 400 years, but finally workers could enjoy as many holidays as they had in the 15th century.

    It was a normal school day for senior Solymar Solis until an unexpected visitor arrived. Her dad, Sgt. Carlos Solis Melendez, surprised her by coming home early from Kuwait and visiting her unannounced at Spring Valley High School in South Carolina.

    After serving in Kuwait for nine months, Melendez returned home a week earlier than his daughter expected. He held balloons and flowers in a classroom as he sat at a student's desk to blend in with the crowd. "It came across my mind like, ‘How is she going to react?" he recalled the heartwarming moment. "Is she going to be happy and run to me and hug me, or cry? That was all going on through my mind."

    As unsuspecting Solymar entered the classroom, she was soon overcome with emotion, immediately bursting into tears and covering her mouth. She didn't talk. She was just crying. She was overwhelmed with everything. She thought it was a dream.

    Melendez was a single parent so while he was deployed (调动), he got his sister to live with his daughter. When he was coming back and talking to his sister, both of them came to the conclusion that they should do something special for his daughter. Melendez and his sister got in touch with the school, and they planned this whole being-in-the-classroom thing, and it turned out perfect.

    The two are very much looking forward to some good daddy-daughter time now that he's home. "It means everything," Melendez said of being able to surprise his daughter this way. "After all the sacrifices she's made, she deserves all the special arrangements and special occasions and celebrations. I'll do anything for my daughter. I believe I'm doing good parenting."

    For several decades, there has been an organized campaign intended to produce distrust in science, funded by those whose interests are threatened by the findings of modern science. In response, scientists have tended to stress the success of science. After all, scientists have been right about most things, from the structure of the universe to the relativity of time and space.

    Stressing successes isn't wrong, but for many people it's not persuasive. An alternative answer to the question "Why trust science?" is that scientists use the so-called scientific method. But what is called the scientific method isn't what scientists actually do. Science is dynamic: new methods get invented; old ones get abandoned; and at any particular point, scientists can be found doing many different things. False theories sometimes lead to true results, so even if an experiment works, it doesn't prove that the theory it was designed to test is true.

    If there is no specific scientific method, then what is the basis for trust in science? The answer is the methods by which those claims are evaluated. A scientific claim is never accepted as true until it has gone through a long process of examination by fellow scientists. Scientists draft the initial version of a paper and then send it to colleagues for suggestions. Until this point, scientific feedback is typically fairly friendly. But the next step is different: the revised paper is submitted to a scientific journal, where things get a whole lot tougher. Editors deliberately send scientific papers to people who are not friends or colleagues of the authors, and the job of the reviewer is to find errors or other faults. We call this process "peer review" because the reviewers are scientific peers—experts in the same field—but they act in the role of a superior who has both the right and the responsibility to find fault. It is only after the reviewers and the editor are satisfied that any problems have been fixed that the paper will be printed in the journal and enters the body of "science."

    Some people argue that we should not trust science because scientists are "always changing their minds." While examples of truly settled science being overturned are far fewer than is sometimes claimed, they do exist. But the beauty of this scientific process is that science produces both creativity and stability. New observations, ideas, explanations and attempts to combine competing claims introduce creativity; transformative questioning leads to collective decisions and the stability of scientific knowledge. Scientists do change their minds in the face of new evidence, but this is a strength of science, not a weakness.
