Like infectious diseases,ideas in the academic world are epidemic (傳染的).But why some travel far and wide while equally good ones has been a mystery?Now a team of computer scientists has used an epidemiological model to simulate(模仿)how ideas move from one academic institution to anojye.air.The model showed that ideas originating at famous institutions caused bigger "epidemics" than equally good ideas from less famous places,explains Allison Morgan,a computer scientist at the University of Colorado Boulder.
   "This implies that where an idea is born shapes how far it spreads," says senior author Aaron Clauset.
   Not only is this unfair - "it reveals a big weakness in how we're doing science," says Simon DeDeo,a professor of social and decision sciences at Carnegie Mellon university,who was not involved in the study. "There are many highly trained people with good ideas who do not end up at top institutions.They are producing good ideas,and we know those ideas are getting lost," DeDeo says. "Our science,our scholarships,is not as good because of this."
   The Colorado researchers first looked at how five big ideas in computer science spread to new institutions.They found that hiring a new faculty member accounted for this movement a little more than a third of the time--and in 81 percent of those cases,transmissions took place from higher – to lower-prestige(聲望)universities.Then the team simulated the spread of ideas using an infectious disease model and found that the size of an idea "epidemic" depended on the prestige of the originating institution.The findings were published online last October in EPJ Data Science.
   The researchers' model suggests that there "may be a number of quite good ideas that originate in the middle of the pack,in terms of universities." Clauset says.There is a lot of good work coming out of less famous places,he says:"You can learn a huge amount from it,and you can learn things that other people don't know because they're not even paying attention."

  • 1.British children's writer Roald Dahl ate chocolates and sweets "pretty much every mealtime",remembers daughter Ophelia Dahl.
       After dinner,whether dining alone or entertaining guests,Dahl would pass around a little red plastic box full of Mars Bars,Milky Ways,Maltesers,Kit Kats and much more.
       He knew the history of all the sweets and could tell you exactly when they were invented.1937 was a big year when Kit Kats (his favorite),Rolos and Smarties (his dog,chopper's favorite) were invented.He wrote a history of chocolate,lecturing schoolchildren to commit such dates to memory(熟記),such as 1928 when "Cadbury's Fruit and Nut Bar popped up on the scene",saying. "Don't bother with the Kings and Queens of England.All of you should learn these dates instead.Perhaps the Headmistress(女校長)will see from now on that it becomes part of the major teaching in this school."
       According to Dahl,the Golden Years of Chocolate were 1930-1937.In 1930,Roald Dahl was 14 years old.He was a student at Repton,a famous boys' boarding school in England.It was a tough environment:those in authority were more interested in controlling than educating the students.
       Ironically(諷刺地),it was at this difficult period that chocolate became Dahl's passion.Near Repton was a Cadbury chocolate factory.Every so often,Cadbury would send each schoolboy a sampler(樣品)box of new chocolates to taste and grade.They were using the students---"the greatest chocolate bar experts in the world to test out their new inventions.
       This was when Dahl's imagination took flight.He pictured factories with inventing rooms with pots of chocolate and fudge(軟糖)and "all sorts of other delicious fillings bubbling away on the stoves".
        "It was lovely dreaming those dreams…when I was looking for a plot for my second book for children.I remembered those little cardboard boxes(紙盒)and the newly invented chocolates inside them,and I began to write a book called Charlie and the Chocolate Factory."
       For the record,Roald Dahl did not like chocolate cake or chocolate ice cream.He said, "I prefer my chocolate straight."

  • 2.Recently,a film star has been giving away free books on the London Underground.If you're a bookworm,a Harry Potter fan and a London Underground user,then it's been an exciting month for you.
       Emma Watson,who starred in films based on the novels about a fictional schoolboy wizard,has been hiding books on the Tube for passengers to read through.
       It's part of he Book On The Underground movement,which has a simple aim:to get more people burying themselves in literature.Books are left on trains for passengers to pick up,dip into and then leave for another lucky reader to skim.

       The 100 or so books Watson left for passengers to read were even more special because she left a hand-written inscription(題詞).The books were Kaya Angelou's Mom & Me & Mom.
       One person who discovered a copy of the book on the Tube said she felt like the character Charlie Bucket - a boy who finds a golden ticket to the world's greatest chocolate factory - in the Roald Dahl's classic,Charlie and the Chocolate Factory Watson became a UN Women Goodwill Ambassador in the summer of 2014 and has since started reading as many books and essays on equality and feminism(饑荒) as possible.She has also started her own book club.

  • 3.It can be really hard to learn a new language.I had always enjoyed learning languages in school,but only recently did I start learning German.I found that I could understand and learn individual words easily,but when it came to literature,I really struggled.That was when my tutor at university suggested reading some children's books printed in the target language.
       At first,I felt a bit silly going on a hunt for a book designed for someone half my age,but then I realised that everyone has to start somewhere.As children,we are given these basic texts to familiarise our brains with certain vocabulary and writing structures,and from there,we can learn and develop.I started with books which are taught to us as children in the UK.I managed to find Oliver Twist by Charles Dickens and James and the Giant Peach by Roald Dahl.
       The beauty of reading books that were introduced to you as a child is that you are already familiar with the plot.Therefore you can work out some words with your knowledge of the story.At first,I used to read with the book in one hand and a dictionary in the other,but this did not work well.The method I would recommend is to read a chapter first and at the end of that chapter,highlight the new words and then look up the definitions.If you can wait a bit before using a dictionary,you may be surprised what you can understand merely from the context.Additionally,a lot of children's books have pictures which may give you a clue as to what or to whom the passage is referring.
       If you can find a translation of the books you have read as a child,I would strongly advise reading those if you are a complete beginner.However,if you feel a bit more confident reading in English,I would personally recommend the series of 'Harry Potter' books by J.K.Rowling or any of the Roald Dahl children's books.

    (1)What makes it hard for the author to learn German?

    A.The author had a poor memory.
    B.The author had no interest in it.
    C.The author had no one to ask for help.
    D.The author couldn't read books fluently.
    (2)What did the author think of reading children's books in the target language at first?

    A.Interesting.
    B.Stupid.
    C.Helpful.
    D.Boring.
    (3)What does the author try to express mainly in Paragraph 3?

    A.How to deal with new words while reading.
    B.Why it is helpful to read children's book at first.
    C.How to choose a proper book to match your level.
    D.How to form the habit of reading in the target language.
    (4)Why does the author write this text?

    A.To give tips on how to learn a new language.
    B.To persuade the readers to learn a new language.
    C.To stress the importance of reading in language learning.
    D.To share the author's stories of learning a new language.
