DNA analysis has revealed family relatio...

    DNA analysis has revealed family relationships between more than 10 generations of Stone Age people at megalithic (巨石的) tombs in Ireland and Sweden.

The evidence suggests that megaliths, prehistoric large stone structures, sometimes acted as graves for family groups in northwestern Europe thousands of years ago. The latest findings throw new light on the origins and social structure of the groups that built megaliths in this region—a history that has long been hidden in mystery.

For their study, the international team of researchers analyzed the genomes—the complete set of genetic material in a cell—of 24 Stone Age individuals from five megalithic burial sites in Ireland, Scotland and Gotland, a large Swedish island in the Baltic Sea.

This analysis showed that many of the individuals buried at each megalith, who all lived between  3,800 B.C. and 2,600 B.C.,  according  to  radiocarbon-dating  of  their  remains,  were closely related via family ties.

The results also showed that the individuals buried at the megaliths were related to Neolithic farmers in northern and western Europe but genetically distinct from other hunter-gatherers. This was particularly noticeable at the Ansarve site on the island of Gotland.

“The people buried in the Ansarve tomb are remarkably different on a genetic level compared to the individuals dug out from hunter-gather contexts, showing that the burial tradition in this megalithic tomb, which lasted for over 700 years, was performed by distinct groups with roots in the European Neolithic expansion,” Magdalena Fraser, co-first author from Uppsala University, said in the statement.

1.What’s the significance of the new findings?

A. It reveals the family ties between people in Ireland and Sweden.

B. It implies that many people buried in the tombs were closely related.

C. It indicates the long-hidden mystery concerning DNA analysis.

D. It suggests that the megaliths became tombs thousands of years ago.

2.How did the researchers reach their findings?

A. By interviewing individuals. B. By travelling to different regions.

C. By analyzing genes. D. By studying the burial sites.

3.Which is true according to the latest findings?

A. Some people buried in the tombs were related to farmers.

B. Few people buried in the tombs were genetically different.

C. All the people buried at megaliths had family relationships.

D. People buried in the Ansarve tomb were dug out 700 years later.

4.What’s the main idea of this passage?

A. Megaliths served as tombs thousands of years ago.

B. People buried at the megaliths were recently analyzed.

C. Latest findings shed light on a mystery about burials.

D. Stone-Age people in Ireland and Sweden had close ties.

    I visited Elba last June, joining Mary and John on a bicycling vacation. They made the arrangements for the car, hotel and bicycles. I studied the history of the island, which of course particularly features Napoleon.

Napoleon (now I know) picked Elba as a place for peace when he was forced to give up the throne (王权) as Emperor of France in 1814. Far from being a prison island, Elba is beautiful with towering mountains, thick forests and sweeping bays and beaches.

It is also an island filled with treasure. Very early on this island, locals discovered rich deposits of iron. Soon outsiders, too, discovered the iron and 150 other valuable minerals on this little piece of land. Long before Etruscans and other Greeks set foot on it, Dorians had moved in by the tenth century B. C. and were mining the island. The Romans ruled next, obtaining the minerals and building grand houses overlooking the sea. From the twelfth century until the nineteenth, the island was traded back and forth and was passed to France in 1802. Then came Napoleon, the new ruler of Elba.

I was eager to visit his house in Portoferraio. The Emperor lived with his court and his mother, but his wife, Marie Louise had ensconced herself in the splendid Viennese palace of her father, Emperor of Austria. She lived safely there and showed little interest in visiting her husband in his mini-kingdom. Apparently, Napoleon wasn’t troubled much by this. He was too busy riding everywhere on horseback, building roads, modernizing agriculture and, above all, sharpening his tiny army and navy into readiness for his escape.

In the formal gardens behind the house it seemed to me that I could imagine the exiled (流放的) conqueror’s anxious thoughts. He might gaze over where I stood now, toward the lighthouse of the Stella fort, the sandy bay, and across it, the green mountains of the Tuscan coast. Napoleon spent only ten months here before making his victorious return to France and the throne.

1.What did the author do for the visit to Elba?

A. He did research on its past.

B. He arranged transportation.

C. He planned bicycling routes.

D. He booked accommodation.

2.Who might be the earliest outsiders to Elba according to the text?

A. Napoleon and his army. B. Etruscans and other Greeks.

C. Dorians. D. Romans.

3.What does the underlined word “ensconced” probably mean?

A. Settled. B. Locked.

4.What came to the author’s mind during his visit to Napoleon’s gardens?

A. Beautiful views on Elba.

B. Terrible living conditions on Elba.

C. Napoleon’s ambition to regain power.

D. Hardship of Napoleon’s return to France.

    Almost none of us have the time to read everything we’d like to read. Yet we lose countless hours to daily activities that bring us little joy like taking buses and waiting in line. What if we could turn these little blocks of unoccupied time into precious and rewarding moments for learning and reflection?

Founded in 2012, iReader, a micro-learning app on mobile phones, brings the biggest ideas from best-selling books through 15-minute audio (音频) and text. So far, more than 3,000 books have been included, ranging from psychology and parenting to management and economics, with new titles added every day.

Reader is pioneering a new method of reading, with over 9 million users enjoying the benefits already. According to the Pew Research Center (PRC), the British read just 4 paper books a year and over 25% haven’t read a single paper book this year, but reading isn’t dying. There are now more ways for the British to read than ever before, due to the widespread use of e-books and audio books.

The books in iReader are rewritten to ensure it is easy to remember the main content. The way the content is edited has been specifically designed to ensure it is useful in practice. Besides, the content is rewritten with relevant examples in real life, which means users are more likely to remember and apply what is helpful to them.

Holger Seim, German co-founder of this app, declares, “iReader gives you the biggest ideas in the shortest possible time. It transforms great ideas into little packs you can listen to or read in just 15 minutes.”

1.What does the author suggest people do in the unoccupied time?

A. Read and think.

B. Write and share.

C. Avoid taking buses.

D. Bring joy to daily routines.

2.What can we infer from the PRC findings?

A. The British benefit a lot from reading.

B. Reading methods are more important than before.

C. Digital technology are taking the place of paper books.

D. New forms of books are changing the way the British read.

3.How does iReader make the content easy to remember?

A. By bringing fun to it.

B. By making it useful.

C. By using artistic designs.

D. By taking users as examples.

4.What is the best title for the text?
