The American newspaper has been around for about three hundred years. In 1721, the printer James Franklin, Benjamin's older brother, started the New England Courant, and that was what we might recognize today as a real newspaper. He filled his paper with stories of adventure, articles on art, on famous people, and on all sorts of political subjects.

    Three centuries after the appearance of Franklin's Courant, few believe that newspapers in their present printed form will remain alive for long. Newspaper companies are losing advertisers, readers, market value, and, in some cases, their sense of purpose at a speed that would not have been imaginable just several years ago. The chief editor of the Times said recently, "At places where they gather, editors ask one another, 'How are you?', as if they have just come out of the hospital or a lost law case.” An article about the newspaper appeared on the website of the Guardian, under the headline “NOT DEAD YET.”

    Perhaps not, but the rise of the Internet , which has made the daily newspaper look slow and out of step with the world, has brought about a real sense of death. Some American newspapers have lost 42% of their market value in the past three years. The New York Times Company has seen its stock drop by 54% since the end of 2004, with much of the loss coming in the past year. A manager at Deutsche Bank suggested that stock-holders sell off their Times stock. The Washington Post Company has prevented the trouble only by changing part of its business to education; its testing and test-preparation service now brings in at least half the company's income.

    “Don't get discouraged, Hallie,” Kathy said, comforting her with a hug. “It sounds as if you have a bit of a mystery to solve. Maybe you should do a little spying on Maya.”

    Feeling better, Hallie put on her scuba gear（潜水服）again and waited. Maya, the dolphin, had been swimming playfully, but suddenly she threw herself to the back of the tank where the filter box（过滤箱）was located. She stuck her nose down behind the box and then swam away.

    Hallie followed Maya. “What was she doing here?” she wondered. When she looked behind the box, her question was answered. She swam back and saw Maya was in front of Kathy with a comb in her mouth waiting for her treat.

    “Maya! Where did you get that?” demanded Kathy, taking the comb and throwing her a fish.

    “I know,” declared Hallie, handing Kathy a handful of items, “I followed her to the filter box and these are what I found.”

From the look on Kathy's face, Hallie knew everything was beginning to come to light.

    “Do you remember the other day you said that Maya really liked her treats?” asked Kathy.“Well, I think this was more than a training exercise for Maya. Every time you found something in the tank, that meant one less fish for Maya. She couldn't bring all the items to me at once, so she found a hiding place for them. That way you came up empty-handed, but Maya would always get her treat.”

    “Okay, Maya,” said Hallie facing the dolphin, “you win! The treats are all yours.”

    Maya dived down, and then jumped out of the water, turning herself over in midair. Shaking their heads in disbelief, Hallie and Kathy reached for the fish. Maya deserved the treat.

    Tom Costello was once afraid of homeless Americans. “I was so afraid that if I saw a homeless person walking down the street, I'd cross the street,” he said.

    That changed seven years ago after his wife, Nancy, a volunteer at a homeless shelter, persuaded him to help with a holiday dinner for shelter residents. Tom remembered going to a store and buying socks for the residents. He knew many of them were in need of clothing.

    At the shelter, Tom said, he dropped a pair of socks into a bag for a woman. She asked him if she could have socks for a friend who wasn't with her that day. He gave her another pair. “She started to cry and told me that nobody had ever given her socks before,” Tom said, “Then she reached out and gave me a hug.” That experience at the shelter helped Tom end his fear of the homeless.

    It also led him to set up a group called “The Joy of Sox.”, which borrows from a name of a popular book. The group collects socks from donors and gives them mostly to shelters in the area where Tom and Nancy live. It has been expanding its reach and provides socks to homeless shelters in 21 states and other three countries now.

    Why socks? Tom explains that some Americans give food, coats and other clothing to shelters. But donating socks is not something most people think about. And, he said, socks are very helpful at keeping people warm, especially in cold weather. A man named Kiwi，who has lived in homeless shelters, said most of the time he could find enough food through shelters and soup kitchens. But socks were much more difficult to get, he noted.

    Windbreaks are barriers (屏障) formed by trees and other plants. Farmers plant these barriers around their fields, which help prevent the loss of soil, stop the wind from blowing soil away. They also keep the wind from damaging or destroying crops. Besides, extra trees and plants can be cut down and used or sold for wood.

    Windbreaks can be highly valuable for protecting grain crops. For example, in parts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared to fields without them.

    But here is something interesting about windbreaks. They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field. If not, then the movement of air close to the ground will lift the soil. Then the soil will be blown away. For this reason, a windbreak works best if it contains only 60 to 80 percent of the trees and plants that would be needed to make a solid line. An easy rule to remember is that windbreaks can protect areas up to 10 times the height of the tallest trees in the windbreak.

    There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees or other plants with leaves. Locally grown trees and plants are considered the best choices for windbreaks. Trees reduce the damaging effects of wind and rain. Their roots help protect soil from being washed away. And trees can provide animals outdoors with shade from the sun.

    Many people all over the world enjoy an alcoholic drink, such as wine or beer, during dinner. Many people raise a glass of alcohol to celebrate a wedding or a birthday. And having drinks after work with friends and co-workers is called "happy hour".

    All these situations are considered "social drinking" because they happen at social events. But when does "social drinking" become problem drinking?

    According to the World Health Organization alcohol abuse kills 3.3 million people each year. That is six percent of all deaths around the world. And in a new report on alcohol use around the world, the WHO says alcohol can create dependency, or addiction, in some people. The report also warns that alcohol use can increase the risk of developing more than 200 diseases, including some kinds of cancers. And, the WHO says alcohol abuse can put people at greater risk of infectious diseases, such as tuberculosis(肺结核), pneumonia (肺炎)and HIV.

    WHO Mental Health and Substance Abuse Director Shekhar Saxena says the organization is concerned about drinking among young people between the ages 15 and 19. And it is most concerned about "binge-drinking", or an extended period of heavy drinking.

    The report concludes that worldwide 16 percent of drinkers over the age of 15 engage in binge-drinking, which is much more harmful than other kind of drinking and causes the most harm in terms of accidents, self-harm and harm to others. High income countries have the highest alcohol consumption and also the highest prevalence(盛行) of binge-drinking.

    The report also found that the highest rates of alcohol-linked deaths are in Europe, followed by the West Pacific and then the Americans. The report also finds Europe is the area with the highest alcohol use. Central and Eastern Europe are especially high.

    The World Health Organization suggests ways countries can protect people from alcohol abuse. These include increasing taxes on alcohol sales, raising the drinking age limit, and controlling the marketing of alcoholic beverages.

    Researchers have been investigating for years the ways in which screens affect the quality of a person's reading. The magazine Scientific American reported that at least 100 studies have been published on the issue since the 1980s.

    Virginia Clinton carried out a research examination. She is a professor of Education, Health and Behavior at the University of North Dakota. She found what she called a "small but significant" difference in reading text from screen versus paper.

    Clinton looked at 33 past studies that examined paper versus screen reading. All of the studies were done between 2008 and 2018. The studies collectively had 2,799 study subjects, including both children and adults. Clinton's examination found that reading from paper generally led to better understanding and improved a person's performance on tests connected to the reading material. And, she found no major differences in reading speed between the two.

    Clinton and other researchers have found screen readers often believe they understand a text better than they really do. And, they are more likely than paper readers to overestimate how well they would do on a test of the materials they have read.

    Yet, this overestimated sense of understanding is especially common among screen readers. Clinton said, "There are many possible reasons for such findings. Overconfidence of reen readers, for example, could be the result of a distracted, less focused mind. Readers' preferences are also important. Research shows the majority of people of all ages prefer reading from paper. If you are enjoying the reading process, you're going to be more involved. You're going to be paying better attention. Preferences are a key issue here."

    Several studies have found that people often think of paper materials as something more important and serious. "If you are reading from paper, your mind thinks this is something important. I need to pay attention to it," Clinton said.
