    Red grouper(石斑鱼) are known for a few key characteristics — their color, which can {#blank#}1{#/blank#}from pink to bright orange; their tastiness, whether they're grilled or fried; and their predation (掠夺行为) method, in which they {#blank#}2{#/blank#} sea creatures and swallow them whole.

    But their least-known characteristic might be the most valuable of all: They operate as underwater architects, {#blank#}3{#/blank#} the seascape for numerous other forms of underwater life. That surprising discovery is {#blank#}4{#/blank#} scientists and policymakers to readjust their approach to preserving the ocean's natural order — and heightening tensions with those who fish for a living or as a hobby.

    A team of scientists, led by Florida State University's Felicia Coleman, recently found that the red grouper off Florida's east and west coasts have created entire ocean {#blank#}5{#/blank#}by digging large holes in the sea's sandy bottom. In the same way beavers {#blank#}6{#/blank#}dams, red grouper dig and maintain distinct holes whose rocky surfaces provide a place for coral, sponges and other marine life to gather.

    This new understanding is changing the way federal and state authorities manage ocean habitats and is creating a completely new crack with fishermen. “The people who are in control want to {#blank#}7{#/blank#} fishing as much as possible,” said Bob Jones, executive director of the Southeastern Fisheries Association. He added that the recent discoveries about red grouper amount to an “excuse they can use to restrict fishing, {#blank#}8{#/blank#}or recreational.”

    But to many researchers, fishery officials and even some fishermen, the fact that fish act as environmental engineers provides a compelling reason to protect them from exploitation.

    “If you {#blank#}9{#/blank#} that fish, it puts into motion a whole chain of events,” said Don deMaria, who used to fish for red grouper near Key Largo, Fla., but no longer does. “There's a whole lot of other animals that are {#blank#}10{#/blank#}. I'm not saying you can't catch them. But you can't do it to the extent we've been doing for the last 20 years.”

    The Smithsonian's National Portrait Gallery was preparing the wall text in 2014 to accompany an image of the boxer Mayweather Jr. During the process, the Washington museum decided to note that Mr. Mayweather had been“charged with domestic violence on several occasions,” receiving “punishments ranging from community service to jail time.”

    Such context is common for {#blank#}1{#/blank#} subjects in art, but far less so for artists themselves. Men like Picasso or Schiele were known for mistreating women, but their works hang in {#blank#}2{#/blank#} museums without any asterisks（星号）.

    Now, museums around the world are{#blank#}3{#/blank#} with the implications of a decision, by the National Gallery of Art in Washington, to {#blank#}4{#/blank#} postpone a Chuck Close exhibition because of {#blank#}5{#/blank#} of sexual harassment（骚扰）involving potential portrait models that have involved the artist in controversy. Mr. Cloze has called the allegations “lies” and said he is “being severely criticized.”

    The {#blank#}6{#/blank#} has raised difficult questions about what to do with the paintings and photographs of Mr. close—held by museums like the Metropolitan Museum of Art in New York, the Tate in London and the Pompidou in Paris, as well as by high-spending collectors—and whether the work of other artists accused of questionable {#blank#}7{#/blank#} needs to be revisited.

    It is a provocative（引起争论的）moment for the art world, as the public debate about {#blank#}8{#/blank#} creative output from personal behavior moves from popular culture into the realm of major visual artists from different eras and the institutions that have long collected and exhibited their pieces.

“We're very used to having to defend people in the collection, but it's always been for the sitter” rather than the artist, said Kim Sajet, director of the Portrait Gallery, which has a large body of Mr. Close's work. “Now we have to think to ourselves, ‘Do we need to do that about Chuck Close?'”

    “You can't talk about portraiture in America without talking about Chuck Close,” she added. “There are lots of amazing artists who have been less than admirable people.”

    Whatever museums {#blank#}9{#/blank#} decide to do about Mr. Close, some say they can no longer afford to simply present art without {#blank#}10{#/blank#} the issues that surround the artist—that institutions must play a more active role in educating the public about the human beings behind the work.

    The Historical Change of Reader's Digest

    During World War I, Mr. DeWitt Wallace was wounded in a battle. During his recovery in the hospital, he read a lot of magazines and {#blank#}1{#/blank#} a lot of interesting information. At the same time, he also found that few people had time to read so many magazines that he realized the idea of excerpting (摘录) these articles and publishing them.

    He was {#blank#}2{#/blank#} to publish a pocket magazine they called Reader's Digest with his wife Lila Acheson. They opened an office downstairs in an illegal hotel in Greenwich Village, New York, and spent only $5,000 in capital and began {#blank#}3{#/blank#} subscribers. After a period of hard work, the first volume was {#blank#}4{#/blank#} published on February 5, 1922. Its purpose is to inform the readers in daily life and give the readers entertainment, encouragement and guidance. The first article, {#blank#}5{#/blank#} How to Stay Young Mentally, was one and a half pages long.

    In 1920, he put {#blank#}6{#/blank#} selected articles into Reader's Digest samples and displayed them to major publishers in the United States. He hoped that someone would be willing to publish them, but they were all {#blank#}7{#/blank#}. Mr. Wallace did not give up and decided to publish it himself. He worked at home with his wife, and finally published the first issue of Reader's Digest in February 1922. The first was printed in 5,000 copies, {#blank#}8{#/blank#} at 25 cents, and sent to 1,500 payment subscribers by mail. By 1935, the circulation of Reader's Digest had reached one million copies.

    The Chinese {#blank#}9{#/blank#} of Reader's Digest was first published in March 1965. The first editor-in-chief was Lin Taiyi, the daughter of Mr. Lin Yutang, master of literature. In November 2004, Reader's Digest and Shanghai Press and Publication Bureau announced the {#blank#}10{#/blank#} of a long-term publishing cooperation.

It is one of the great unsolved {#blank#}1{#/blank#}of this century.

He was being very {#blank#}2{#/blank#}about where he was going.

Can a precise word total ever be known? No, says Professor David Crystal, known chiefly for his research in English language studies and author of around 100 books on the {#blank#}1{#/blank#}. "It's like asking how many stars there are in the sky. It's impossible to answer," he said.

An easier question to answer, he {#blank#}2{#/blank#}, is the size of the average person's vocabulary. He suggests taking a sample of about 20 or 30 pages from a medium-sized dictionary, which {#blank#}3{#/blank#} about 100,000 entries or 1,000 or 1,500 pages.

Tick off the ones you know and count them. Then {#blank#}4{#/blank#} that by the number of pages and you will discover how many words you know. Most people vastly underestimate their {#blank#}5{#/blank#}.

"Most people know half the words—about 50,000—easily. A reasonably educated person about 75,000 and a really cool, smart person well, maybe all of them but that is rather {#blank#}6{#/blank#}. An ordinary person, one who has not been to university say, would know about 35,000 quite easily."

The formula can be used to calculate the number of words a person uses, but a person's active language will always be less than their {#blank#}7{#/blank#}, the difference being about a third.

Prof Crystal says exposure to reading will obviously expand a person's vocabulary but the level of a person's education does not {#blank#}8{#/blank#} decide things. "A person with a poor education perhaps may not be able to read or read much, but they will know words and may have a very {#blank#}9{#/blank#} vocabulary about pop songs or motorbikes. I've met children that you could {#blank#}10{#/blank#} as having a poor education and they knew hundreds of words about skateboards that you won't find in a dictionary."
