Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released (发布) five simple rules for preparing food in a safe way. They call these rules the “Five Keys to Safer Food”.

Key 1: Keep clean

    {#blank#}1{#/blank#}People should wash their hands often — before touching food and while they are preparing food. People should wash all surfaces and equipment used for preparing food.

Key 2: Separate raw (生的) and cooked

    Raw foods should not touch prepared foods.{#blank#}2{#/blank#}.

Key 3:{#blank#}3{#/blank#}

    People should cook eggs and meat especially carefully. These foods may carry more micro-organisms (微生物) than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.

Key 4: Keep food at safe temperatures

    When people finish eating, they should keep the left food in a refrigerator below 5℃and shouldn't store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms.{#blank#}4{#/blank#}.

Key 5: Use safe water and raw materials

    {#blank#}5{#/blank#}. Damaged or old food may develop harmful chemicals as it gets older.

A. Cook completely

B. This key tells about the importance of washing

C. Eat healthily

D. They can live where we make food

E. People should use safe water and choose fresh foods

F. They cannot grow as quickly in a very hot or very cold environment

G. People should use separate equipment and tools for touching and preparing raw foods

    Tim Richter and his wife, Linda, had taught for over 30 years near Buffalo, New York – he in computers, she in special education. "Teaching means everything to us," Tim would say. In April 1998, he learned he would need a heart operation. It was the kind of news that leads to some serious thinking about life's purpose.

    Not long after the surgery, Tim saw a brochure describing Imagination Library, a program started by Dolly Parton's foundation (基金会) that mailed a book every month to children from birth to age five in the singer's hometown of Sevier, Tennessee. "I thought, maybe Linda and I could do something like this when we retire," Tim recalls. He placed the brochure on his desk, "as a reminder."

    Five years later, now retired and with that brochure still on the desk, Tim clicked on imaginationlibrary.com. The program had been opened up to partners who could take advantage of book and postage discounts.

    The quality of the books was of great concern to the Richters. Rather than sign up online, they went to Dollywood for a look-see. "We didn't want to give the children rubbish," says Linda. The books – reviewed each year by teachers, literacy specialists and Dollywood board members – included classics such as Ezra Jack Keats's The Snowy Day and newer books like Anna Dewdney's Llama Llamaseries.

    Satisfied, the couple set up the Richter Family Foundation and got to work. Since 2004, they have shipped more than 12,200 books to preschoolers in their area. Megan Williams, a mother of four, is more than grateful: "This program introduces us to books I've never heard of."

    The Richters spend about ＄400 a month sending books to 200 children. "Some people sit there and wait to die," says Tim. "Others get as busy as they can in the time they have left."

    Words and the way we use them offer a rare window on social and cultural trends. Kory Stamper and Peter Sokolowski know that better than most.

    The Merriam-Webster(韦氏词典) lexicographers(词典编纂者) are part of a team that edits the dictionary. In a recent interview, Sokolowski and Stamper talked about their job and what the way we use words says about us collectively.

    So to know more about them, observers of the language, maybe we should start with some background.

    What is a lexicographer?

    Sokolowski: A lexicographer is a person who writes or edits a dictionary. The job of a dictionary editor is to prepare and present research about language. One of our former editors-in- chief said, "Tell the truth about words," and that sums it up for me.

    What do you guys do all day?

    Stamper: The two main duties of a lexicographer are reading and defining. We read everything: books, journals, blogs, phone books, take-out menus, and so on. What we're looking for are words that catch our eye. We record the context of these words and information about the sources. Those records are added to a database, and they are the raw material we use in writing definitions.

    When we are writing or revising a dictionary, most of our time is spent defining. We define a word according to how it is used in the recorded context, deciding whether the usage has been covered by our dictionary. Once this is done, you look at the new words and new senses and draft a definition.

    Drafting definitions requires some training, some experience and a lot of concentration. It's very, very quiet on the editorial floor.

    How closely do the most looked-up words on your online dictionary seem to be related to the news or trends?

    Stamper: When our dictionary went online back in 1996, we could see for the first time which were the most looked-up words in English: Affect, effect and ubiquitous were the top words. It was fascinating to us­dictionary editors spend so much time writing definitions but never could have known if anyone ever read them. We could follow what people were thinking about according to what words they were looking up. Thanks to our online dictionary, we had data.

    In the shadow of Kenya's Mount Kilimanjaro, nine Rothschild giraffes, the rarest giraffes on the planet, are free to wander at the English-style manor (庄园). Every day shortly before 9am, they come up to the house and stick their heads through the windows and doors in search of morning treats. The manor's owners, Tanya and Mikey Carr-Hartley, share their dining table with them. And now the couple are sharing the fantastic experience with the public by opening the manor gates to guests at the giraffe hotel, the only hotel of its kind in the world. Now, guests can feed the giraffes at breakfast but can also get up close to them from their second-floor bedrooms.

    Mr and Mrs Carr-Hartley, both 38, spent their childhood living close to the house in Nairobi and have always been enthusiastic about the animals. Tanya said, "Mikey and I grew up near this manor house when we were children. We are both third generation Kenyans and have always wanted to work in conservation. Mikey's family have been related to the protection of animals for many generations. His granddad helped the removal of giraffes as far back as the 1930s because the Rothschild giraffes lost much of their natural living space. When the house came up for sale, we jumped at the chance to buy it as we had always dreamed of owning it. Now, we were absolutely overjoyed to do something for the giraffe protection. Having the giraffes so close is very special and something which people can now experience by staying in one of the ten rooms at the hotel."

    A conservation project to save them was started at the manor in 1974 by the previous owners. "The previous owners ran a very successful breeding (繁殖) programme, where many giraffes were set free into the wild and we hope to continue," said Tanya.

    Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.

    Despite the celebrations, though, in the U. S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.

    It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

    "Jazz seems like it's not really a part of the American appetite, "Moran tells National Public Radio's reporter Neal Conan. "What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It's actually color, and it's actually digital. "

    Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. "The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same, "says Moran.

    Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, "just to kind of put it back in the mind that Waller is dance music as much as it is concert music," says Moran. "For me, it's the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context," says Moran, "so I want to continue those dialogues. Those are the things I want to foster. "
