    "There's Always a John" By Darla Boyd

    My first year of teaching, there was a kid named John in my class. John was difficult to control and he nearly drove me crazy. While talking about him one day, an old teacher put his hand on my shoulder and said, "There will always be a John. Your job is to learn to discover what makes him different and help him succeed." The next year, there was indeed another John. But that advice taught me that there is something to appreciate in everyone.

    "An Early Key Lesson" By Elaine West

    Before I began my first teaching job, my mother, a teacher of 30 years, gave me a very special gift, five simple words that have had an effect on my entire life." Make friends with the janitor（门卫）." Her wisdom taught me the respect for all types of characters and continues to enrich my life to this day. Just five little words but what an impact they can have when you take them to heart.

    “Raising Mommy” By Jan Davis

    Being a mother can always present challenges and rewards. Someone told me early that children will teach you everything you need to know. Being a mother is being raised. Our children become our advisers. Their dreams become our professors, as we are taking notes carefully. The sounds of their laughter and smiles are a great reward to us. Their tears remind us that it is okay to fail, and that we should wipe the tears away and try again.

    Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard.

    In the early years, these schools were much alike. Only young men went to colleges. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them become ministers or teachers.

    In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history.

    As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.

    Today there are many different kinds of colleges and universities. Most of them are made up of smaller schools that deal with special fields of learning. There's so much to learn that one kind of school can' offer it all.

    Standing in line for the latest iPhone at the Apple store  queuing for tickets to the match or even just waiting at the post office might just have got a lot easier.

Japanese car-maker Nissan announces that it has just the thing to relieve the painful legs of tired queuers.

    The new system of self-driving chairs is designed to detect when someone at the front of the queue is called, and automatically move everyone else one step forward in line.

    The new invention is shown in a company video, which shows a busy restaurant with customers waiting outside. In the video, diners are sitting in a row of chairs, but will not have to stand when the next hungry diner is called to a table. Instead, the chairs, equipped with autonomous technology that detects the seat ahead, move along a path toward the front of the line. When the person at the front of the queue is called, the empty chair at the front can sense it is empty and so moves out of line. Cameras on the remaining chairs then sense the movement and follow automatically.

    “The system, which is similar to the kind used in Nissan's autonomous vehicle technology, will be tested at select restaurants in Japan this year," Nissan said. "It appeals to anyone who has queued for hours outside a crowded restaurant: it rids the boredom and physical pain of standing in line,” Nissan added.

    Although Tokyo has some 160,000 restaurants, long queues are not uncommon. Chosen restaurants that meet the criteria will be able to show the chairs outside their restaurants next year. Nissan also released a short video showing the chairs being used in an art gallery, moving slowly in front of the various paintings to let viewers appreciate the art without the need to stand up.

    A new study suggests some language learning can take place during sleep. Researchers from Switzerland's University of Bern say they discovered people were able to learn new language words during deep levels of sleep.

    Much of the earlier research found that memories made when awake were strengthened during sleep. This supported the idea that information learned while awake is replayed and deeply embedded in the sleeping brain.

    The researchers theorized that, if replay during sleep improves the storage of learned information while awake, the processing and storage of new information should also be possible during sleep.

    They carried out experiments on a group of young German­speaking men and women, which centered on periods of deep sleep called "up­states". They identified these slow­wave peaks as the best moments for sleep­learning.

    The researchers observed individuals in a controlled environment during brief periods of sleep. Brain activity was recorded as pairs of words were played for the study subjects. One word in the pair was a real German word. The other was a made­up foreign word. For later identification purposes, the German words chosen were things clearly larger or smaller than a shoebox.

    Each word pair was played four times, with the order of the words changed each time. The word pairs were played at a rhythm that is similar to actual brain activity during deep sleep. The goal was to create a lasting memory link between the false word and the German word that individuals could identify while awake.

    When the subjects woke, they were presented with the false language words­both by sight and sound. They were then asked to guess whether the false word played during sleep represented an object smaller or larger than a shoebox. Results of the study found that a majority of subjects gave more correct answers about the sleep­learned words than would be expected if they had only guessed at random.

    The researchers said they measured increased signals affecting a part of the brain known as the hippocampus. This brain structure is very important for building relational memory during non­sleep periods. The researchers also said memory was best for word pairs presented during slow­wave peaks during sleep.

    The study suggests that memory formation in sleep appears to be caused by the same brain structures that support vocabulary learning while awake. The researchers say more studies are needed to support their findings. However, the experiments do provide new evidence that memories can be formed and vocabulary learning can take place in both conscious and unconscious states.

Do you know that junk food isn't healthy? Of course you do! Do you eat it anyway? Of course you do! But a new study shows teaching adolescents about the ways food companies fool them into thinking junk food is cool can encourage kids to fight back—by eating healthier.

The pull of junk food can be super-strong. It's designed to be tasty, which makes eating well one of the great health challenges of our time. Everyone from doctors to the government has been trying to handle it. Yet we keep eating junk food.

Professor Christopher Bryan says, "Food companies want you to want junk food." They spend millions of dollars coming up with new ways to promote junk food consumption. They hire scientists to make new junk food almost irresistible. They might do this, for example, by adding more sugar. Rats fed junk food for six weeks will even walk across a floor that gives them electric shocks just to get more of such food.

Food ads often make unhealthy junk food seem healthy by featuring professional athletes, fit-looking pop stars and smiling, active teens. "We thought when the students learned this, it would matter to them," Bryan says. He worked with 8th graders at a Texas school. Half of them got a lesson Bryan created. It focused on the ways junk food is advertised, or marketed. A second group received lessons that focused on health. These lessons informed students junk food is bad, and that foods like apples or carrots are a better choice. The students learned a bad diet can lead to major weight gain, and that being overweight puts people at risk for serious diseases. They also learned how eating well now can keep you healthy when you're older.

After the lessons, the kids in both groups were asked how they felt about junk food. Most didn't have positive feelings about these unhealthy foods.
