Philo Farnsworth is not a name most people know. But his work changed the way we learn, the way we live, and even the way we think. Philo Farnsworth is responsible for one of the 20^th century: television.

    Philo Farnsworth was born in America in 1906. He was interested in science and technology at an early age. When he was twelve years old, he built an electric motor for his family's washing machine. When he was fourteen, he was already giving a lot of thought to electrons（电子）. As he was driving the family's horse-drawn plowing machine, he noticed the evenly spaced rows of the potato fields. This sight gave him the idea that electrons could scan（扫描） an image one row at a time—an idea that was the key to electronic television.

    By the time he was twenty-one years old, Farnsworth had started his own company and had managed to build the world's first electronic television. It was a very simple device（设备）. But after years of hard work, Farnsworth was able to introduce the kind of television we now use.

    Farnsworth was a great inventor, but lived an unhappy life. He had a legal battle with the company, Radio Corporation of America (RCA) over who the real inventor of the TV was. He won the case, but the government stopped companies from making TVs during the war, so Farnsworth didn't make much money from the invention.

    When Farnsworth was young, he imagined television as a convenient way for distant audiences to enjoy lectures by famous professors, or entertainment by the best symphonies（交响乐） and ballets. When he was older, television became much more popular, but he was very disappointed in the silly programs on TV. He even told his own son, “There's nothing on it worthwhile, and we're not going to watch it in this household.”

    A thief entered the bedroom of the 30th President of the United States, who met him and helped him escape punishment.

    The event happened in the early rooming hours in one of the first days when Calvin Coolidge came into power, late in August, 1923. He and his family were living in the same third­floor suite (套房) at the Willard Hotel in Washington that they had occupied several years before. The former President's wife was still living in the White House.

    Coolidge awoke to see a stranger go through his clothes, remove a wallet and a watch chain.

    Coolidge spoke, “I wish you wouldn't take that.”

    The thief, gaining his voice, said, “Why？”

    “I don't mean the watch and chain, only the charm (表坠). Take it near the window and read what is impressed on its back.” the President said.

    The thief read, “Presented to Calvin Coolidge.”

    “Are you President Coolidge？” he asked.

    The President answered, “Yes, and the House of Representatives (众议院) gave me that watch charm. I'm fond of it. It would do you no good. You want money. Let's talk this over.”

    Holding up the wallet, the young man said in a low voice, “I'll take this and leave everything else.”

    Coolidge, knowing there was $80 in it, persuaded the young man to sit down and talk. He told the President he and his college roommate had overspent during their holiday and did not have enough money to pay their hotel bill.

    Coolidge decided to offer the man and his roommate two rail tickets back to the college. Then he counted out $32 and said it was a loan (借款)．

    He then told the young man, “There is a guard in the corridor.” The young man nodded and left through the same window as he had entered.

    Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.

    One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.

    Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.

    Romer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.

    Romer called these earliest four-footed animals “tetrapods”. Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.

    Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer's theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.

    According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.

    The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK's University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”

    As is often the case, however, there are others who find the theory less convincing. Cambridge University's paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It's only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.

    In 2012, Kim Stemple, a special-education teacher, found herself in a Boston hospital being treated for one of several diseases she had been diagnosed(诊断) with, including lupus and lymphoma. The normally confident Stemple was naturally getting very depressed. And then a friend gave her a medal.

    Before she got too sick to exercise, Stemple had been a marathon runner. The medal came from a racing partner who had just finished a half marathon in Las Vegas and hoped the souvenir would act as a kind of feeling pick-me-up. It worked like a charm­and then some.

    After Stemple hung the medal near her hospital bed, other patients said they wanted medals too. That got Stemple thinking. "A medal is a simple way to give a positive message," she told pilotonline.com. And so was born her charity, We Finish Together, which collects medals from strangers­runners, dancers, swimmers, singers, and even spelling bee winners-and donates them to all sorts of people in need.

    Those who received the medals have included hospital patients, residents of homeless shelters, and veterans. Part of the process involves the donor writing a personalized note on the ribbon. "This gives them a connection to someone," says Stemple. "If they receive a medal, they know someone cares."

    Can a simple medal really make a difference? Yes, says Joan Musarra, who suffers from pulmonary fibrosis. "I opened my package containing my new medal and the notes of positive, warm thoughts, I was overwhelmed," she wrote to Stemple. "At that moment, I was sitting on my couch breathing through life-support machine because my lungs have been worsening so badly. It means so much to me to feel that I am not alone."

I stood outside my front door catching my breath. After a lazy Christmas holiday, I had to recover from climbing stairs with carry-on bags and a suitcase. I looked up — Red tape crossed the door. I didn't understand French, but the one English word said enough, "POLICE". Google Translate told me I would be caught if I entered, so I didn't.

Finally, I called my rental agent (收租人). He went to the police station for more details. The thief had taken a few items from the top drawer as well as a small amount of money in the bottom drawer. Not only were my files undisturbed, but so were the TV and printer. My agent also said something about fixing the locks tomorrow and making a list for the police.

Then one day, I remembered that I had left another jewelry box in the flat. My heart sank as I thought of a gold locket (项链坠) with a picture of my late Grandma inside. When I realized the box was missing, the whole experience seemed to crash down on me. I cried. At the end of January, I received a letter from the police. The thief hadn't been found, and the case was closed. I slept with my purse by my bed. I hid my laptop when I showered. And then another challenge came — I was unexpectedly fired by my company.

One July night, I reached into my third drawer to pull out my jean shorts. I heard something fall to the ground. I looked down: It was the tiny jewelry box I thought had been stolen six months earlier. Inside was the locket with honey Grandma smiling at me, being there for me, telling me not to give up. I started to cry. I knew that things were going to be OK.

The Lantern Festival falls on the first full moon of the new lunar year. The Festival, with{#blank#}1{#/blank#}history of over 2,000 years,{#blank#}2{#/blank#}(date) back to the Han Dynasty. The festival originates from an Act, released by Emperor Wendi of the Western Han Dynasty, {#blank#}3{#/blank#}(honor) deities(神明) and ancestors with lantern displays.

A large quantity of customs and traditions are associated with the Lantern Festival, one of {#blank#}4{#/blank#} is the lighting of Lanterns that {#blank#}5{#/blank#}(display) in different shapes and sizes. In many northern parts of China, grand lantern displays featuring diverse sizes and themes, create an attractive scene, {#blank#}6{#/blank#}, in the south, the tradition of floating lanterns offers a beautiful gesture of releasing the past to embrace the future. More than just a visual feast, the lanterns are part of China's intangible cultural heritage, representing hope and renewal as they light up the {#blank#}7{#/blank#}(dark) to welcome the new year.

{#blank#}8{#/blank#}important tradition is the solving of lantern riddles. Lantern owners write riddles on pieces of paper and attach them to their lanterns while festival-goers of all ages stroll among the lights, trying to solve these riddles. {#blank#}9{#/blank#}(basic), successful solvers often receive gifts, adding to the festive atmosphere.
