One night, the first floor of the house suddenly caught fire. The fire was big, and soon became a sea of fire. On the second floor lived a little girl and her grandmother; the little girl's parents had died, and she lived together with her grandma. In order to rescue the little girl, the grandmother was burned to death, leaving the little girl crying for help loudly.

    How could people enter the house? At the very moment, a man carrying a ladder rushed to the flames and entered the house through the window. When he appeared again in the eyes of the people, the little girl was in his arms. He gave the child to the crowd, and then disappeared into the night.

    This little girl had no family. Two months later a meeting was held to find a person to adopt the girl. A teacher was willing to adopt this child, and said she could give her the best education; a farmer wanted to adopt this child, saying that village life would let the child grow up healthily and happily; a rich man said, “I can give the child everything that others can do.”

    A lot of people who wanted to adopt this child said a lot about the benefits of their adopting the child. But the little girl's face had no expression. At this time, a man, through the crowd, walked straight to the little girl, and opened his arms for the little girl. People were puzzled, and they found that the man had terrible scars on his arms. The little girl let out a cry, “This is the man who saved me!” She suddenly jumped up and buried her face in his arms and sobbed. Naturally the man adopted the girl.

    China is a country of many resources. Among its resources are many great rivers, which provide useful transport routes. Water transport is an efficient way to carry heavy loads, such as grain. In ancient times, a waterway was needed between China's rich farmlands and the capital city. This need inspired engineers to build a canal. According to writings by the ancient thinker Confucius, work on a canal linking the Yangtze River with the city of Huai-in began about 486 B.C. For many centuries afterward, Chinese emperors worked on extending this ancient canal.

    This canal is now known as China's Grand Canal. One thousand years after the original canal was begun, it was in extreme need of repair. This was in the year 607, during the Sui Dynasty. By 610 the emperor had had the canal extended. The Grand Canal formed a northeast-southwest link between the Yellow River in the north and the Huai River in the south. The canal remained the main waterway in this part of China for the next five hundred years.

    In the thirteenth century, the Mongols had conquered China. The Yuan Dynasty established Beijing as the capital. The city's growing population needed food, so a new canal was built to extend shipping. Building this part of the Grand Canal required enormous effort and cost. Neither the first attempt nor the second one was successful, so the builders chose another route. Finally this link in the Grand Canal was finished.

    By the time of the Ming Dynasty, the Grand Canal had six sections. These were busy with goods until the nineteenth century. Then a series of severe floods struck China. Parts of the Grand Canal were badly damaged. By 1868 it had been largely abandoned as a means of northern route.

    The Grand Canal was mostly restored in the twentieth century. It was widened and deepened, and a new section was constructed. Today the canal, which is about 1,200 miles in length, has new locks(运河的水闸). It is busy with ships and barges(驳船) carrying goods to and from cities along its banks.

    I've recently published a book of letters from 32 amazing Australian women about their experiences of new motherhood. Perhaps the most common question I've been asked since publication is why more of the mothers didn't ask for help. If those early months were so hard and so exhausting as they were described, then why didn't more of these women simply ask for help?

Embedded (把……牢牢地嵌入) deep in this enquiry is the assumption that if you ask, you shall receive—and that you shall receive without judgment. And if there is any experience of new motherhood in the 21^st century it is the inescapability of judgment. By asking for help new mothers open themselves up to a wave of quiet—and not-so-quiet—disapproval of why on earth they need it.

    The earliest moments of motherhood are synonymous with sacrifice(等同于牺牲). A mother sacrifices her body for not nine but almost ten long months, sharing her shell with a new being. A mother sacrifices her control, and often her mental and physical health, during the painful process of childbirth. A mother, in the weeks and months that follow, puts the needs of another before her own, sacrificing her sense of self, her ambition and all too often, her happiness.

    We don't normally use the word sacrifice to describe the newborn period. It's supposed to be sweet and milky and warm but a sacrifice is exactly what it is. And when we sacrifice we should be entitled (使享有权利) to mourn—a privilege new mothers are expressly prevented from.

    We have reached the point where being a mother who admits she needs help is like saying your child isn't worth the sacrifice. The suffering has become a badge(徽章) of honor, worn in service to your family.

    The role of mothering is not an easy one, nor will it ever be. But it could be made more manageable if we were all to offer help or support.

    The next time your brain refuses to recall a simple fact or name, be thankful. That could be a sign that your brain is getting rid of unnecessary information so that it can operate more efficiently, and help you make better decisions.

The researchers say there are numerous neurobiological(神经生物学的)studies conducted on how the brain stores information, a process called persistence (暂留). However, scientists also assumed that our occasional inability to recall facts was due to a are an the brain. In 2013, scientists discovered that as new neurons combine with the hippocampus(海马区)—a region of the brain that plays a significant role in learning and remembering—they overwrite old memories, making them harder to access. There is also evidence that the brain weakens or removes connections between neurons, in which memories are encoded.

    The scientists have a theory on why the brain spends so much energy erasing memories. They say what the brain decides to forget is determined by our daily life. An example is that our brains remember phone numbers according to the need. Instead of storing this irrelevant information that our phones can store for us, our brains are freed up to store the memories that actually do matter for us. They also believe that memorizing too much detail could prevent us from making good decisions.

    So the next time you are unable to recall a seemingly important fact, don't be hard on yourself. Just throw it to your brain's “rubbish can” to make room for information that can contribute to making you smarter! Remember, even Albert Einstein was absent-minded!

    Sally Dawly is a woman from Auburn, California. Over the last three and a half years, the anti-littering woman has spent most of her free time picking up cigarette butts (烟头) from the streets of her home city.

    Called the "Butt Lady" by her local community, Dawly began her mission to rid the streets of her city of cigarette butts in October, 2014. The woman looked for cigarette butts, picked them up and threw them in the trash. To keep a count of how many butts she picks up, the Butt Lady has been using a tablet, and earlier this month, she hit a historic milestone—one million cigarette butts.

    "I got tired of going on my walks and seeing cigarette butts everywhere," Sally Dawly said. "I'm just shocked that I had to pick up so many. I've ever picked up 3,000 butts in one day," she said. "Don't throw away your butts; better yet, stop smoking."

    With so many cigarette butts littering the streets, can one person's efforts really make a difference? Surprisingly, the answer seems to be yes. Soon after the Butt Lady of Auburn started her mission and word of her efforts spread, cigarette cans started appearing around bars and restaurants in the city. Members of the local community even came out to cheer her on as she approached her one-million-butt milestone.

    Sally knows her city's cigarette butt littering problem won't be solved anytime soon, but she hopes her work will inspire people to at least think twice before dropping cigarette butts in the streets. She has decided to continue cleaning up after irresponsible smokers, and already has a new milestone in her sights—two million cigarette butts.

    Word of the Butt Lady's efforts to keep the streets cigarette butt-free has reached neighboring communities as well, and CBS Sacramento reports that other cities have started seeking her help as well.

    There have been many problems with our schools today, the biggest of which is closely related to our culture. In general, our culture, as represented in the media, gets excited by famous stars, and constantly stresses that it's what you have, not what you are, that counts. Parents are encouraged to be away from even very small children for most of the day. Too many voters go for politicians who would rather cut school funding than to get rid of tax cuts for the wealthy. All contribute greatly to the problems of educating our children.

    Today's teachers have to deal with a culture that is vastly different than in the past. They report that there is, among more children than ever, a lack of motivation, no drive to succeed or even try. The role models that boys view in the media mostly consist of men in comedies and other shows who are rude and often extremely immature; self-centered overpaid athletes; men in movies, television dramas, video games, etc. who are preoccupied with violence and power. As Leonard Sax wrote in "Boys Adrift", "Teenage boys are looking for models of mature adulthood, but we no longer make any collective effort to provide such models." Girls are attacked not only with such annoying images of males, but also with women who are preoccupied with appearance and are extremely materialistic.

    In such a cultural environment, it is more important than ever to have responsible, loving and caring parents who have enough time and motivation to devote to their children and see to it as their duty to model for them and raise them with high standards of honesty and responsibility along with tending to their physical needs. They need to care enough to see that their children are not attacked with the garbage that comes from movie, television and computer screens. In today's culture, they are basically alone in this effort since, unfortunately, so much is working against them.

    Until we, as a culture, face the truth about ourselves — that we are not providing adequately for a great many of our children — the storm will continue to rage over our education system.
