    The Parthenon(帕特农神庙) in Athens is a building with a long and complex(复杂的) history. Built nearly 2,500 years ago as a temple celebrating the Greek goddess Athena, it was for thousands of years the church of the Virgin Mary of the Athenians, then a mosque (清真寺), and finally a ruin. The building was changed and the sculptures(塑像) much damaged over the centuries. By 1800 only about half of the original sculptural decoration remained.

    Between 1801 and 1805, Lord Elgin, the British ambassador to the Ottoman Empire(奥斯曼帝国), which controlled Athens, acting with the full knowledge and permission of the Ottoman authorities，removed about half of the remaining sculptures from the fallen ruins and from the building itself. Lord Elgin loved Greek history and transported the sculptures back to Britain. The arrival of the sculptures in London had a huge effect on the European public, greatly increasing interest in ancient Greek culture and influencing contemporary artistic trends. These sculptures were gained from Lord Elgin by the British Museum in 1816 and since then they have all been on show to the public, free of charge.

    Since the early 1980s, however, the Greek government has argued for the return of all the Parthenon sculptures in the British Museum. They have also challenged the British Museum Board of Trustees' legal title to the sculptures.

    The British Museum, however, insists that it exists to tell the story of cultural achievement throughout the world, from the dawn of human history over two million years ago until the present day. The museum considers itself an important resource for the world: the breadth and depth of its collection allows the world public to re-examine cultural identities and explore the complex network of interconnected world cultures.

    It also says that, within the context of this unparalleled collection, the Parthenon sculptures are an important representation of ancient Athenian civilization. Each year millions of visitors admire the artistry of the sculptures and gain insights on how ancient Greece influenced — and was influenced by — the other civilizations that it came across.

    A new study says electronic toys are not helping babies learn.

    "Even if companies are marketing them as educational, they're not teaching the babies anything at this time," said Anna Sosa the study's author.

    Researchers listened to audio(声音的) recordings of parents playing with their babies aged 10 months to 16 months. The researchers compared the experiences when the children played with electronic toys, traditional toys such as blocks, or when the children looked at books. What they found is that parents talked less with their babies when the babies played with electronic toys.

    Why is this important? Research shows that how quickly children develop language is often based on what they hear from parents. When the infants played with electronic toys, parents said little to their children. But with traditional toys, such as blocks, parents shared the names and descriptions of the animals, colors and shapes as their children played. There was even more information given by parents as their babies looked at the pictures in books.

    Of course, there is no need for parents to throw out electronic toys, but they should look at their infants' play with such toys as entertainment, not a learning experience.

    Toy Industry Association spokeswoman Adrienne Appell responded to the study. She said it is important that parents make time to play with their children. "Playing is a way that kids can learn so much, not only cognitive(认知的) skills, but social and developmental skills," she said. She added that play should be balanced, including time for just "make believe" activities, as well as traditional and electronic toys.

    Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy (星系).The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. It was captured by the Event Horizon Telescope (EHT).

    The announcement was made in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo. Details have been published today in Astrophysical Journal Letters.

    Prof Heino Falckc, of Radboud University in the Netherlands, who suggested the experiment, told BBC News that the black hole was found in a galaxy called M87. "What we see is larger than the size of our entire Solar System," he said. "It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute monster, the heavyweight champion of black holes in the Universe."

    The image shows an intensely bright "ring of fire", as Prof Falckc describes it, surrounding a perfectly circular dark hole. The bright halo is caused by very heated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth. The edge of the dark circle at the center is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull (万有引 力）,not even light can escape.

    "It is remarkable that the image we observe is so similar to that which we get from our theoretical calculations. So far, it looks like Einstein is correct once again." said Dr Ziri Younsi, of University College London -who is part of the EHT cooperation.

    Chinese scientists were involved in the observation through a telescope in Hawaii. They were also highly involved in follow-up data processing and theoretical analysis, said Shen Zhiqiang, head of the Chinese Academy of Sciences' Shanhai Astronomical Observatory and a member of the EHT international team.

    Shanghai and Taipei were selected as two of the cities to hold news conferences, together with Washington, Brussels, Santiago and Tokyo, a recognition of China's contribution.

    "In the fields of astronomy, radio astronomy, and space astrophysics, China has made a significant contribution to this global project," Falcke said.
