          You must have been amused by videos of dogs waving tails happily at their owner's home-coming greetings,or pictures of cats looking so guilty after making the house a mess.A variety of domestic animals can distinguish between their owner's voice and the voices of others,and can even detect changes in tone.But whether wild animals can recognize individual humans is a bit unclear.
             A new study led by Roberta Salmi is the first to show that wild gorillas,too,are able to recognize familiar human voices based on their relationship with the speaker.
             Over the course of about six months,the researchers played the gorillas audio recordings of three groups:long-term keepers who knew and worked with the gorillas for at least four years and had positive relationships with them;people who the gorillas knew and had negative interactions with,including vets and the service workers;and people who were unfamiliar to the animals.All the participants said the same phrase, "Good morning.Hello," which is how keepers typically greet the gorillas.
             The gorillas had the least reactions to the voices of their keepers.However,when they heard the voices of people they didn't know or with whom they'd had negative experiences,the gorillas responded with signs of vigilance. They stopped eating their treats or whatever else they were doing and started looking toward the sound to judge whether the voices were a threat.
             "It's something we do too," said Salmi, "If it's not a threatening sound,I keep doing my own business.If I hear that there is someone in my house,I immediately stop what I'm doing to hear what's going on."
             If wild gorillas are able to distinguish by voice and have different reactions to humans,according to whether they are hunters or researchers,it would be extremely helpful. "They know when something is wrong and can try to hide or escape danger," Salmi said. "It would help me sleep better to know that researchers aren't making the gorillas become easier targets to hunters."

          • 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."

               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 movement started in 2012 and drops off about 150 books a week in stations across London.Talking about Watson's participation in the project,the manager of Books On The Under ground,Cornelia Oxley,said, "The reaction has been great.It must be a mixture of how much everyone admires Emma,and how exciting it is to find something as wonderful as a new book on your journey."
               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.

          • 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.
