What should we do when we are in a bad situation? Some may choose to give up. But is that what we should do? The following news report may get you encouraged.

    With a population of 156 million, Bangladesh has one of the largest populations in the world. What makes the situation worse is that most of the country is situated on the low-lying Ganges delta(三角洲). As a result, it often suffers flooding, especially during the rainy season from July to October. In this period, the rivers rise as much as 12 feet. In such situations, people can only get to certain places by boat.

    The problems are particularly serious in the Chalanbeel region, a poor area where people survive by farming on the rich delta soil when it is not underwater. But many parents there don't want to send their children to school and there are not enough teachers. As a result, many kids living there do not attend school on a regular basis. The problem becomes worse during the rainy season when land schools cannot be reached. Many students never return to school after the forced breaks.

    How to help students attend school regularly? 22-year-old Bangladeshi architect Mohammed Rezwan decided to take action. In 2002, the young man used $500 he had received in scholarships to start Shidhulai Swanirvar Sangstha. The non-profit organization's mission was to set up floating schools. It took Rezwan four years to raise enough funds to open his first boat school. But as the world began to know about the organization's worthy cause, money started to pour in. Until now, Shidhulai Swanirvar Sangstha has built 22 floating schools, some with playgrounds on the upper deck. Now a lot more children in the Chalanbeel region go to school regularly.

    We should keep in mind that there is always a solution to every problem.

    Have you ever been to the world's smallest bookstore?

    The World's Smallest Bookstore, whose official name is just these three words, sits quietly about 100 miles northeast of Toronto.

    The bookstore is about 10 feet by 10 feet，so it is easy to imagine how tiny it really is. The bookstore is open 24 hours a day. Inside the bookstore are various books, especially literary books and classic authors' works. So if you are looking for something less popular, you may get a bit disappointed there.

Another special feature of this bookstore is that each book only costs three dollars. All the expenses are paid on the honor system, which means buyers should make a note of what they've bought and leave their money by themselves. So the tools of the trade in this bookstore are quite simple: pens, papers, light bulbs and a label-maker.

    In order to catch passers-by's attention, the billboards (广告牌) of the bookstore are several times bigger than the store itself. With these large eye-catchers, many people are willing to stop by and have a visit.

    The single, decisive factor that made it possible for mankind to settle in lasting communities（社区，聚居地）was agriculture. After farming was developed in the Middle East in about 6500 BC, people living in family units did not have to be on the move continually searching for food or hunting their animals. Once people could control the production of food and be assured of a reliable supply of it, their lives changed completely.

    Farming was a revolutionary discovery. It not only made settlements possible and later the building of cities but it also made available a reliable food supply. With more food available, more people could be fed. Population therefore increased. The growing number of people available for more kinds of work led to the development of new social formations. With more and more food, a community could support a variety of workers who were not farmers.

Farming in the world over has always relied upon a dependable water supply. For the earliest societies this meant rivers and streams or regular rainfall. The first great civilizations grew up along rivers. Later communities were able to develop by taking advantage of the rainy seasons.

    All of the ancient civilizations probably developed in much the same way, in spite of a few differences. As villages grew, the production of more numerous goods became possible. Cloth could be woven from wool. Houses made of wood, brick, and stone could be put up.

    The science of mathematics was an early outcome of agriculture. People studied the movements of the moon, the sun, and the planets to work out seasons, By doing so they created the first calendars（日历）. With a calendar it was possible to find out the arrival of each growing season. Measurement of land areas was necessary if field was to be divided accurately. Measurement of amounts, for example, of seeds or grains was also a factor in farming and housekeeping. Later measures of value as money exchange became common.

    All of the major ancient civilizations in Mesopotamia, Egypt, the Indus Valley, and China appeared in the 4th millennium（千年）BC. Historians still argue over which one came into being first. It may well have been the Middle East. This place reaches out from the Nile River in Egypt northward along the coast of former Palestine, then eastward into Asia to include Mesopotamia. In this area people settled along the riverbanks and practiced field agriculture. This kind of farming depended on the reproduction of seed, normally from grain crops.

    We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic（共鸣的）.They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic expression. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    More and more people in America are celebrating the Indian holiday Diwali. Diwali is Hindi for “row of lights.” It is the most important holiday in India.

    Many people around the world are beginning to celebrate it as well. The United States is one of the places where the festival is becoming more common. Diwali celebrations can now be found at American landmarks like Disney land in California and New York City's Times Square. They are also held in many parks and museums.

    Neeta Bhasin created the Times Square event. She said Indian immigrants (移民) have found great success in America. But, she said, many Americans still do not know much about India. So, she decided to act. "I felt it's about time that we should take India to mainstream America and show India's rich culture, heritage, arts and variety to the world, "she said, "And I couldn't find a better place than the center of the universe: Times Square."

    Bhasin came to the United States from India 40 years ago. She is president of ASB Communications, the marketing firm behind Diwali at Times Square. Tens of thousands of people attend the event, now in its fourth year.

    In India, Diwali is a five-day harvest festival held just before the Hindu New Year. The exact dates change from year to year but Diwali is always in the fall. Celebrations include lighting oil lamps or candles called diyas. The lights represent "a victory of knowledge over ignorance, light over darkness, good over evil."

    A Diwali celebration will light up Disney California Adventure Park in Anaheim this year. Visitors can watch performances of traditional Indian dances and take part in a Bollywood dance party. The event is part of a Festival of Holidays program at the theme park to show cultural traditions from around the world.

    Mary bought a dress in a women's clothing store.She felt very happy about buying the dress until she got home. Then she remembered she had left her purse at the store.It was the third time that month that Mary had forgotten something important.Mary was angry with herself.She said,“Am I losing it?”

    Emma was teaching a class in mathematics at a college.She began to explain to the students how to solve a very difficult problem.She understood it very well.But somehow,at that moment,she could not explain it.Emma said,“I must be losing it.”

    Americans seem to have a lot of concern about losing it.At least that is what you would think from hearing them talk.They use the expression when they feel they are losing control.It can mean losing emotional control.Or losing the ability to do something.Or losing intelligence.

    Word experts differ about how the expression started.Some believe it came from television programs popular in the 1980s.Others believe it began with psychologists,who deal with how people think,feel and act.

    “We Americans have many concerns about controlling our lives.Perhaps we worry too much,”one psychologist said.“In many situations to say you are losing it eases the tension（不安）.”

    It's healthy.And most people who say they are having a problem are not losing it.

    People may feel more like they are losing it when they are “down in the dumps”.Word expert Charles Funk says people have been feeling down in the dumps for more than 400 years.The word dumps probably comes from Northern European countries.The languages of Denmark and Norway both have similar words.The words mean to fall suddenly.Americans borrowed this saying.And,over the years,it has become a popular way of expressing sadness.
