Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we are often able to know where most words come from.

    Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburger. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Germans did not understand the question and answered. “We came from Hamburger.” One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburger ate. Then he put each between two pieces of bread and started selling them. Such bread came to be called “ hamburgers”.Today “hamburgers” are sold in many countries around the world.

    Whether this story is true or not, it is certainly is interesting. Knowing why any word has a certain meaning is interesting, too. The reason, for most English words, can be found in any large English dictionary.

    Mark Twain left school when he was twelve. He had little school education. In spite of (尽管) this, he became the most famous writer of his time. He made millions of dollars by writing. His real name was Samuel Langhorne Clemens, but he is better known all over the world as Mark Twain, his pen-name.

    Mark Twain was born in 1835 and he was not a healthy baby. In fact, he was not expected to live through the first winter. But with his mother's tender care, he managed to survive. As a boy, he caused much trouble for his parents. He used to play jokes on all of his friends and neighbors. He didn't like to go to school, and he constantly ran away from home. He always went in the direction of the nearby Mississippi (密西西比河). He was nearly drowned (淹死) nine times.

    After his father's death in 1847, Mark twain began to work for a printer, who only provided him with food and clothing. Then, he worked as a printer, a river-boat pilot and later joined the army. But shortly after that he became a miner. During this period, he started to write short stories. Afterwards he became a full-time writer.

    In 1870, Mark Twain got married. In the years that followed he wrote many books including Tom Sawyer in 1876, and Huckleberry Finn in 1884, which made him famous, and brought him a great fortune (财富).

    Unfortunately, Mark Twain got into debts in bad investments (投资) and he had to write large numbers of stories to pay these debts. In 1904, his wife died, and then three of their children passed away.

    At the age of 70, his hair was completely white. He bought many white suits and neckties. He wore nothing but white from head to foot until his death on April 21, 1910.

    Sue Hendrickson is a self-taught fossil（化石）hunter. As a kid, Sue Hendrickson often walked with her head down. “People said, 'Look up. Smile!” she says. “Now, I realize I was born to look for things and just didn't know it.”

    Sue Hendrickson does more than look—she finds valuable things: Shipwrecks（沉船）with treasure, ancient sunken cities, and in 1990, she found Sue, the world's largest, most complete Tyrannosaurus rex（霸王龙）. Is Hendrickson lucky? Well, maybe. But she also knows how to look.

    “I limit the area where I'm going to look,” she says. No one knew the location of the sunken ship San Diego in the Philippines. For a year, Hendrickson and other researchers searched papers and sailors' diaries. “The descriptions of the ship's sailors led us to the wreck,” she says. The team also used a tool that can respond to metal. This tool found the San Diego. All the work paid off. The 400-year-old ship was complete, with valuable gold and silver coins.

    To find the dinosaur she calls “the biggest animal that ever walked on earth,” Hendrickson started with maps made to search for oil. What Hendrickson found was the largest and most complete T-rex found to date. The T-rex is 42 feet long with 200 bones! Because it is so complete, scientists were able to infer that Sue walked at about 6 miles per hour and did not run faster than 15 miles an hour. Before Sue was discovered, they thought T-rex was much faster. To learn more about T-rex Sue, go to the Field Museum in Chicago.

    There's plenty left to be found, Hendrickson says, including answers to mysterious such as how T-rex lived. “I tell kids that they need to grow up and work them out because all of us old persons haven't yet!”

    Little Women is the story of four sisters growing up during the Civil War. Each March (马奇) sister has a different personality. Meg, the oldest, is dignified (端庄) and proper. Jo, next in age, is energetic and wants to be a writer. Beth is shy and quiet and loves music. Amy, the youngest, is spoiled (被宠坏的), a little conceited (自负), and enjoys art. In the following passage, an excerpt(节选)from Chapter 14 Secrets, Jo has a secret surprise to tell her sisters. Laurie is the boy who lives next door, and Hannah is the March's servant. The Spread Eagle is a newspaper in the town.

    In a few minutes Jo bounced (蹦跳) in, laid herself on the sofa, and pretended to read.

    "Have you anything interesting there?" asked Meg, with condescension (屈尊).

    "Nothing but a story, won't amount to much, I guess," returned Jo, carefully keeping the name of the paper out of sight.

    "You'd better read it aloud. That will amuse us and keep you out of mischief (恶作剧)," said Amy in her most grown-up tone.

    "What's the name?" asked Beth, wondering why Jo kept her face behind the sheet.

    "The Rival Painters."

    "That sounds well. Read it," said Meg.

    With a loud "Hem!" and a long breath, Jo began to read very fast.

    The girls listened with interest, for the tale was romantic, and somewhat pathetic (哀婉动人), as most of the characters died in the end. "I like that about the splendid picture," was Amy's approving remark, as Jo paused.

    "I prefer the lovering part. Viola and Angelo are two of our favorite names, isn't that strange?" said Meg, wiping her eyes, for the lovering part was tragical (凄婉).

    "Who wrote it?" asked Beth, who had caught a glimpse(瞥) of Jo's face.

    The reader suddenly sat up, threw away the paper, displaying a red face, and with a funny mixture of solemnity and excitement replied in a loud voice, "Your sister."

    "You?" cried Meg, dropping her work.

    "It's very good," said Amy.

    "I knew it! I knew it! Oh, my Jo, I am so proud!" and Beth ran to hug her sister, wild with joy over this splendid success.

    Dear me, how excited they all were, to be sure! How Meg wouldn't believe it till she saw the words. "Miss Josephine March," actually printed in the paper. How politely Amy criticized (批评) the artistic parts of the story, and offered advice for a sequel (续集), which unfortunately couldn't be carried out, as the hero and heroine were dead. How Beth got excited, and skipped and sang with joy. How Hannah came in to shout in great astonishment at 'that Jo's doin's'. How proud Mrs March was when she knew it. How Jo laughed, with tears in her eyes, as she declared she might as well be a peacock(孔雀) and done with it, and how the 'Spread Eagle' might be said to fly his wings proudly over the House of March, as the paper passed from hand to hand.

    "Tell us about it." "When did it come?" "How much did you get for it?" "What will Father say?" "Won't Laurie laugh?" cried the family, all in one breath as they gathered around Jo, for these foolish, affectionate (痴情的) people had a celebration of every little joy of family.

    Last week, Vodafone started a test of the UK's first full 5G service, available for use by businesses in Salford. It is part of its plan to trial the technology in seven UK cities. But what can we expect from the next generation of mobile technology?

    One thing we will see in the preparation for the test is lots of tricks with the new tech. Earlier this year, operators paid almost £ 1.4 billion for the 5G wavelengths, and to compensate for that cash, they will need to catch the eye of consumers. In September, Vodafone used its bit of the range to display the UK's first hologram (全息) call. The Manchester City captain Steph Houghton appeared as a hologram in Newbury. It isn't all holograms, however: 5G will offer faster internet access, with Ofcom (英国通讯管理局) suggesting that video that takes a minute to download on 4G will be available in just a second.

    The wider application is to support connected equipment on the "internet of things" -not just the internet-enabled fridge that can reorder your milk for you, but the network that will enable driverless cars and delivery drones (无人机) to communicate with each other.

    Prof William Webb has warned that the technology could be a case of the emperor's new clothes. Much of the speed increase, he claims, could have been achieved by putting more money in the 4G network, rather than a new technology.  Other different voices have suggested that a focus on rolling out wider rural broadband access and addressing current network coverage would be more beneficial to the UK as a whole.

    Obviously, 5G will also bring a cost to consumers. It requires a handset for both 5G and 4G, and the first 5G-enabled smart phones are expected in the coming year. With the slow pace of network rollout so far, it is likely that consumers will end up upgrading to a new 5 G phone well before 5 G becomes widely available in the next couple of years.
