Lucy, whose skeleton（骨骼） was discovered in Ethiopia in 1974, died shortly after she fell out of a tree, according to a new study published Monday in the British journal Nature.

    For their research, Kappelman and Dr. Richard Ketcham used a CT scanner to create more than 35,000 "slices" of Lucy's skeleton. Scientists named her Lucy from the Beatles song "Lucy in the Sky with Diamonds", which was played at the camp the night of her discovery.

    The following analysis of the slices showed sharp, clean breaks seen at the end of Lucy's right humerus （肱骨） are similar to bone breaks seen in victims of falls.

    The researchers concluded that these and other breaks in her skeleton show that Lucy, who is believed to have stood about 3 feet 6 inches and weighed about 60 pounds, fell feet first and used her arms to support herself﹣but that the injury was too severe to have been survivable.

    The researchers estimate that Lucy was going about 35 miles an hour when she hit the ground after falling from a height of roughly 40 feet, according to the statement.

    That sounds plausible. But other scientists are doubtful. "There are countless explanations for bone breaks," Dr, Donald C, Johanson, director of the Institute of Human Origins and one of the scientists who discovered Lucy, said, "The suggestion that she fell out of a tree is largely a just﹣so story and therefore unprovable." Johanson said it was more likely that Lucy's breaks occurred long after she died, saying that "elephant bones appear to have the same kind of breaks, It's unlikely they fell out of a tree.

    But the new research focused on "a small number of breaks" that are consistent with "high﹣energy bone﹣to﹣bone influences" and which differ from the sorts of breaks commonly seen in other collected bones. Kappelman responded in an email, "These appear to have occurred at or near the time of death."

Pride and Prejudice for the Modern Woman

    Let us imagine how Pride and Prejudice, Jane Austen's most famous work, might be updated, 200 years on. Austen's popularity is rooted in her intelligence. But today she would certainly have had a very different life, as would her characters(角色). Here's my own suggestion…

    It is a truth finally and universally acknowledged that a single woman with brains deserves to have equal opportunities to men, however disadvantaged she may feel by sexism.

    "My dear husband," said his hopeful wife one day," have you heard that the local store, standing empty for so long, is taken over by a bright young businesswoman?"

    Her dull and indifferent (漠不关心的) husband replied that he had not. "But it is, it is," she replied excitedly. Mr. Dull-Husband made no reply.

    "Don't you want to know her plans?" she cried with some impatience.

    "Well, clearly you think it matters to your silly little head, so I'd better listen."

    "Well, my dear, the rumour (传言) is that she has already set up a string of successful businesses in northern England, though how a woman can know anything about that is beyond me". She will move in herself next month." "What is her name?" "Bingley."

    "Is she married or single?"

    "What a question! And none of your business. But her coming will be a fine thing for our five boys." "How so? How can it possibly affect them?"

    "My dear love; those lazy boys need something to wake them up. There are bound to be jobs going."

    "Is that her point in settling here? Surely as a woman she has simply taken a fancy to the place."

    "Nonsense, my love, how little you've noticed the world has changed. She's got a first-rate degree and some sort of business qualification, I'm told. She surely needs one of our boys! Perhaps you might give her a call."

    "Me? No. Perhaps you can take an interest. You still have your looks, after all. She may even offer you a job." "Oh, that's not likely. These new chances belong to the younger generation. But now you mention it, I think I'll go along all the same."

    And Mrs Bennet went along. That was 10 years ago. She is now managing director of a FTSE-listed company.

    It would remain the case, of course, that Mrs Bennet would be one of very few women on the company board, that her salary would be lower than her male colleagues, her bonus of a more "female" dimension(方面) and her lifespan (年限) among the city's business leaders shorter than theirs. Still, she'd no doubt have enjoyed Davos(达沃斯经济论坛)—and might even have hobnobbed (攀谈) with influential figures.

    Auctions (拍卖行) are everywhere. Here are just a few standouts and some of the areas they specialize in. All have brick-and-mortar (实体的) sales rooms in addition to online buying.

    Leslie Hindman Auctioneers

    Headquarters (总部): Chicago

    Founded: 1982

    Best bets: contemporary art, jewelry

    The founder, Leslie Hindman, has been on an expansion kick from her Chicago base and now runs eight offices across the country. Ms. Hindman said that plenty of items sell at her house for around $500. As in the auction world generally, jewelry and contemporary art receive lots of attention from bidders (出价者), and in 2017 a diamond ring sold for $97,000.

    Swann Auction Galleries

    Founded: 1941

    Best bets: books, works on paper, African-American art

    Founded as a rare-book auctioneers, Swann still holds dozens of such sales a year. The president, Nicholas D. Lowry, noted that Swann was the first auction house to sell old photographs, in 1952. The house has also had a department of African-American art for 12 years.

    Stair Galleries

    Headquarters : Hudson, N. Y.

    Founded: 2001

    Best bets: English and Continental furniture and paintings, modern and contemporary art

    Colin Stair, the founder and president, comes from a long line of antiques dealers. Stair is frequented by dealers and bargain hunters, and it's a place to find interesting things like a Gorge I carved walnut wing armchair, coming up as part of a sale on April 28 and 29.

    Heritage Auctions

    Headquarters : Dallas

    Founded: 1983

    Best bets: coins, sports memorabilia, movie posters

    With roots in coin auctions Heritage has grown quite large. But their bread and butter are items that the company president, Greg Rohan, calls "the kinds of things that everyone has." "People aren't buying what we're selling for decoration or for resale," he added. "They're buying things they absolutely love."

    Over the past couple of days, on our local Freecycle page there have been a lot of wanted posts, all from the same person, basically asking for everything you'd need to set up a house from scratch.

    One of the things they asked for was a queen-sized bed. At that time we just happened to have an extra one, so I messaged them. They immediately came in the afternoon. The people who came, two ladies and a man, are actually friends of another woman named Jenny who owned a young boy. This woman has escaped from a dangerous, violent relationship and these friends of hers are helping her and her son start over again, with everything from furniture to toothbrushes on their list of needs.

    While they were here, I also gave them one of our spare bookcase and some coffee cups. I even asked them to keep in touch in case they needed anything else—I have a way of connecting people with things. I offered the woman a cupboard we had as well; her friends just needed to see if there was a place and/or a need for it in their friend's new home.

    I was so excited to meet those loving people, who were obviously willing to help their friend. It was clear how protective they felt of this woman and her boy, how much they love her and wanted her to have a happy and safe life, and to spend even a few minutes with people like that is an experience I'll remember for a long, long time.

    A quick thank-you to all who have sent more donations over the last couple of days, as well as lovely messages of thanks and blessings. Sometimes it's hard to keep up with it all, but it's a problem I'm happy to have.

    Miep Gies, the woman who hid the Dutch girl Anne Frank's diary from the Nazis to become one of the world's most-read books, died after a brief illness at the age of 100.

    It was Gies who guarded Anne's diary, and presented it to the girl's father, Otto, when he returned from the Auschwitz concentration camp(奥斯威辛集中营) at the end of World War Ⅱ—the only one of his family to survive.

    In her diary, Anne Frank wrote about her teenage life hiding from the Nazis in Amsterdam from 1942 to 1944, when the Nazi police discovered her and her family's hiding place. The diary, first published in 1947, has been translated into 70 languages.

    Anne Frank expressed a great wish to live on after her death. Miep Gies saw it as her duty to help in making this happen.

    Born in Vienna in 1909, Gies moved to the Netherlands at the age of 11. In 1933, she began working for Otto Frank at his trading company. At great risk to her own safety, she and four other helpers brought food and supplies to the Frank family hiding in a secret office building for more than two years.

    When she turned 100, Gies tried to play down her own role. "I'm not a hero," she said. "It wasn't something I planned in advance. I simply did what I could to help."

    Every day she received letters from all over the world with questions about her relationship with Anne Frank and her role as a helper. Gies received many honors for her role, including from the Netherlands, Germany and Israel.

Fishy Weather Conditions

    Laj amanu，Australia，is a dry little town，sitting right on the edge of the Tanami desert. Can you imagines How surprised were people when live fish rained down on them from a dark gray cloudy. It happens that there are similar cases in England and Honduras.

    How do clouds make fishy. The simple answer is that they don't. There is a particular weather phenomenon(现象)called a waterspout. A waterspout is just like a tornado，only it forms above oceans，lakes，or rivers. Like a tornado，a waterspout moves in a circle at high speeds. When it moves above the water，it tends to carry the fish with it，as well as frogs or other small plants or animals.

    Scientists couldn't work it out at first. To make matters stranger still，the fish in Honduras were very much alive when they rained down to the ground，but they were all blind. In England and Australia，it rained fish and snakes，and none were blind. It was difficult to puzzle out，but the blind fish gave them a place to start.

    Scientists knew that some fish that lived in deep，underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras，scientists began to connect some dots. Clearly，these particular fish were pulled from an underground water source by force.

    It has rained fish on every continent，and each time，people have tried in various ways to explain this strange phenomenon. Historically，villagers thought the “fishes from the heavens” might be answers to prayers for food. Others suggested that floods overran river banks and oceans，leaving the fish on the city streets. No scientist had actually seen the rain as it occurred，only the fish left on the ground. But in 1990，a National Geographic team happened to be in Honduras when the Rain of Fishes began. They recorded what was happening and made history by finally proving that the fish really did fall from the sky.

    This huge breakthrough wasn't just a spot of good luck. It changed thousands of years of myths and legends into true stories and provided scientific explanations for how fish came to live in deep caves. It explained ancient cave paintings and shed new light on how species have spread over time. It turned out to be a lot more than just a little fishy weather.
