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."
1.What can we know about Lucy from Kappelman and Dr. Richard Ketcham's research?
A. She got her name from a song.
B. She had more than 35,000 slices.
C. She couldn't use her arms properly.
D. She made an effort to save herself.
2.What does the underlined word "plausible" in Paragraph 6 probably mean?
A. Reasonable. B. Creative. C. Surprising. D. Unbelievable.
3.Which of the following would Johanson probably agree?
A. Elephants are unlikely to die from falling.
B. Lucy got breaks at or near the time of death.
C. Other reasons for the breaks should be considered.
D. Lucy's bone breaks differ from other bone breaks.
4.What conclusion can we draw from the passage?
A. Lucy didn't die from falling out of a tree.
B. The newly published study was meaningless.
C. The argument on how Lucy died will continue.
D. Scientists will find another way to solve the problem.

“Mum, what does it mean when someone tells you that they have a skeleton(骨骼)in the closet(衣橱)?” Jessica asked. “A skeleton in the closet?” her mother paused thoughtfully. “Well, it’s something that you would rather not have anyone else know about. For example, if in the past, someone in Dad’s family had been arrested for stealing a horse, it would be ‘a skeleton in his family’s closet’. He really wouldn’t want any neighbor to know about it.”
“Why pick on my family?” Jessica’s father said with anger. “Your family history isn’t so good, you know. Wasn’t your great-great-grandfather a prisoner who was transported to Australia for his crimes?” “Yes, but people these days say that you are not a real Australian unless your ancestors arrived as prisoners.” “Gosh, sorry I asked. I think I understand now,” Jessica cut in before things grew worse.
After dinner, the house was very quiet. Jessica’s parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica’s closet. Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor. Jessica’s mother sank in a faint(晕倒), waking only when Jessica put a cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.
“What happened? Where am I?” she asked. “You just destroyed the school’s skeleton, Mum,” explained Jessica. “I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad.” Jessica looked in amazement as her parents began to laugh madly. “They’re both crazy,” she thought.
1.According to Jessica’s mother, “a skeleton in the close” means ______.
A. a family honor B. a family story C. a family secret D. a family treasure
2.What can we learn about some Australians’ ancestors form Paragraph 2?
A. They were brought to Australia as prisoners.
B. They were the earliest people living in Australia.
C. They were involved in some crimes in Australia.
D. They were not regarded as criminals in their days.
3.Jessica’s mother fell down into a faint because she was ______.
A. frightened B. knocked C. injured D. surprised
4.Why did Jessica bring a skeleton home?
A. She planned to keep it for fun.
B. She needed it for her school task.
C. She was curious about it.
D. She intended to scare her parents.
5.Jessica’s parents laughed madly at the end of the story probably because ______.
A. they were crazy
B. they were over excited
C. they realized their misunderstanding
D. they both thought they had won the quarrel

A German fisherman named Konrad Fischer found the brown bottle near Kiel,Germany. He said he nearly threw the bottle back into the water after pulling it out of a fishing net. Then he noticed something inside.
The bottle in good condition contained a Danish postcard with two German stamps,dated May 17,1913. Although dampness had made most of the writing illegible(字迹模糊的),thereadable part of the message asked whoever found it to return it to an address in Berlin. It even contained two stamps to pay for postage.
From the address,researchers found that the postcard was written by a man named Richard Platz,who was 20 years old when he wrote the message. While he was hiking on the Baltic coast with a nature appreciation group,he threw the bottle into the sea. Then the researchers began a search for any living relatives of his. Sure enough,they were able to find his 62-year-old granddaughter,Angela Erdmann,who still lives in Berlin.
“It was almost unbelievable,”Erdmann said upon being presented with her grandfather's bottle and message.“That was a pretty moving moment. Tears rolled down my face."
Erdmann never knew her grandfather,who died in 1946,but says that the discovery of the bottle has made her want to learn more about him.
The bottle remained on display at the International Maritime Museum in Hamburg until May 1 .After that,the researchers examined the postcard and tried to figure out the meaning of the rest of the message.
Previously,the oldest message found in a bottle spent nearly 98 years at sea and was discovered in April 2012,according to Guinness World Records.
