Visitors to Britain are sometimes surprised to learn that newspapers there have such a large circulation (发行 ). The “Daily Mirror “ and the “Daily express” both sell about four million copies everyday. British families generally buy a newspaper every morning and two or three on Sundays.

    Besides the national papers, there is, however, another branch of the British press which sells almost as many copies. Local newspapers have a weekly circulation of 13 million. Almost every town and county area has one. Nearly all of them hold their own financially (财政 ) and many of them are very profitable (赚钱的 ) .

    These papers are written almost entirely for readers interested in local events-births, weddings, deaths, council (地方会议 ) meetings and sports. Editors prefer to rely on people who know the district well. A great deal of local news is regularly supplied by clubs and churches in the neighborhood and it does not get out to date as quickly as national news.

    The editors must never forget that the success of any newspaper depends on advertising ( 广告) . He is usually anxious to keep the good will of local businessmen for this reason. But if the newspaper is well written and the news items have been carefully chosen to draw local readers, the business men are grateful for the opportunity (机会 ) to keep their products in the public eyes.

    The old man walked with a cane（拐杖）slowly into the restaurant. His poor jacket.

    patched（打补丁）trousers and worn-out shoes made him stand out from the usual Saturday morning breakfast crowd. Unforgettable were his pale blue eyes that sparkled like diamonds，large rosy cheeks，and thin lips held in a steady smile.

    He walked towards a table by the window. A young waitress watched him and ran over to him， saying，“Here, Sir. Let me give you a hand with that chair”

    Without a word，he smiled and nodded a thank you. She pulled the chair away from the table. Steadying him with one arm， she helped him move in front of the chair， and get comfortably seated. Then she pushed the table up close to him，and learned his cane against the table where he could reach it.

    In a soft，clear voice he said, “Thank you, Miss”

    “You are welcome, Sir.” she replied，“My name is Mary. I'll be back in a moment. If you need anything, just wave at me.”

    After he had finished a hearty meal of pancakes，bacon，and hot lemon tea，Mary brought him the change, helping him up from his chair and out from behind the table. She handed him his cane， and walked with him to the front door. Holding the door open for him, she said, “Come back and see us, Sir.”

    He nodded a thank you and said softly with a smile, “You are very kind！”

    When Mary went to clean his table，she was shocked. Under his plate she found a business card and a note written on the napkin, under which was a 100$ bill.

    The note on the napkin read，“Dear Mary，I respect you very much， and you respect yourself，too. It shows by the way you treat others. You have found the secret of happiness. Your kind gestures will shine through those who meet you. ”

    The man she had served was the owner of the restaurant. This was the first time that she，or any of his employees, had seen him in person.

    At 2:30 on December 5,1945, five US Navy training planes took off in clear weather from the base Lauderdale, Florida. The planes flew cast over the coast...and disappeared. The group was Flight 19, on a run between Florida and Bahamas. Tailor was the group leader. At about 3:40, Tailor reported that his compasses were not reading properly. The other planes followed their leaders aimlessly, first east, then west, then northeast over the ocean, as Tailor tried to make sure of the direction by radio. Then, suddenly Tailor was heard to give orders to dive...

    Quickly, two giant Martin seaplanes were sent up to search for Flight 19. Several hours later, the wind became strong and visibility (能见度) dropped. A return to base was ordered. But only one of the Martin seaplanes landed. Four days later, the Navy and Coast Guard combed a 100,000 square miles area with more than 100 planes and ships. No sign was ever shown of the missing planes.

Today, people have noted the disappearance of many ships and planes in the southwest part of the North Atlantic and began to call this area the Bermuda Triangle(百慕大三角区).

    The points of the triangle are Bermuda, Puerto Rico and a spot in the Gulf of Mexico, west of Florida. It is a two-faced water world of tiny islands, bright beaches and beautiful waters. Yet thick fogs, powerful currents(激流) and sudden storms are hidden behind this smiling surface.

    An 80-year-old man was sitting on the sofa in his house along with his 45-year-old son. Suddenly a crow (乌鸦) landed on their window.

    The father asked his son, "What is that?"

    The son replied, "That is a crow."

    After a few minutes, the father asked his son for the second time, "What is this?"

    The son said, "Father, I told you just now. It's a crow."

    After a little while, the father asked his son the same question for the third time, "What is this?"

    This time, the son said to his father in a low and cold tone, "It's a crow, a crow."

    After a moment, the father yet again asked his son for the fourth time, "What is this?"

    This time his son shouted at his father, "Why do you keep asking me the same question again and again? I have told you already, ‘IT IS A CROW'. Are you not able to understand this?"

    A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page.

    Today my little son aged three was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I didn't at all feel angry, but instead felt affection for my son.

    If your parents reach old age, do not look at them as a burden, but speak to them gently, and be kind to them. From today say this aloud, "I want to see my parents happy forever. They have cared for me ever since I was a little child. They have always showered me with love. I will take care of my old parents in the best way no matter how they behave."

    Artificial intelligence can predict when patients with a heart disorder will die, according to scientists.

    The software learned to analyze blood tests and scans of beating hearts to spot signs that the organ was about to fail. The team, from the UK's Medical Research Council, said the technology could save lives by finding patients that need more aggressive treatment. The results were published in the Journal of Radiology.

    According to the researchers, high blood pressure in the lungs damages part of the heart, and about a third of patients die within five years after being diagnosed. There are treatments: drugs, injections straight into the blood vessels, a lung transplant. But doctors need to have an idea of how long patients might have left, in order to pick the right treatment.

    The software was given scans of 256 patients' hearts, and blood test results. When this data was combined with eight years of patient health records, the artificial intelligence predicted when patients would die.

    The software could look about five years into the future. It correctly predicted those who would still be alive after one year about 80% of the time. The figure for doctors is 60%.

    The team now want to test the software works in other patients in different hospitals before assessing whether it should be made widely available to doctors. The researchers also want to use the technology in other forms of heart failure, such as cardiomyopathy, to see who might need a pacemaker or other forms of treatment.

    Dr Mike Knapton, from the British Heart Foundation, said, "This exciting use of computer software in medical practice will help doctors in the future to make sure that patients are receiving the correct treatment before the condition deteriorates and leaves them needing a lung transplant. The next step is to test this technology in more hospitals with heart disease."

A new study examines possible harm caused by microscopic pieces of plastic that end up inside people's bodies. These materials -known as microplastics and nanoplastics - can enter the body through the air or in food or drinks.

One new study suggests the buildup of such plastics inside the body can increase the risk of a stroke, heart attack or death. But the researchers noted the evidence presented cannot prove a direct link between tiny plastic materials and heart problems.

The study involved 257 people who had medical operations to clear blocked blood vessels （血管） in their necks. Italian researchers examined the fatty buildup the doctors removed from the carotid arteries, which supply blood and oxygen to the brain. Using two methods, they found evidence of plastics-mostly nanoplastics that cannot be seen-in the artery plaque（动脉斑块）of 150 patients. No evidence of plastics was seen in 107 patients.

The team followed these people for three years. During that time, 30 individuals, or 20 percent of the group with plastics, had a heart attack, stroke, or died from any cause. These rates dropped to about eight percent among those with no evidence of plastics. Research results were recently published in a study in the New England Journal of Medicine.

The researchers admitted their study was very small. For example, it only looked at people with narrowed arteries who were already at risk for heart attacks and stroke.

Steve Nissen is a heart expert at the Cleveland Clinic in the state of Ohio who was not part of the study. He told the Associated Press he thinks the team's estimate that the risk of heart attack, stroke or death was four times greater seems too high. "It would mean that these microplastics are the most important cause of coronary heart disease （冠心病） yet discovered. And I just don't think that's likely to be right," Nissen said. "Maybe, it's just a wake-up call that perhaps we need to take the problem of microplastics more seriously." Nissen added.
