試題詳情
For centuries,tea has been used for far more than quenching thirst.Around the world people drink it to relax,reinvigorate and relieve,and it's something we need now more than ever.
Even in the United States,a long coffee-dominated country,tea drinking is growing in popularity,with the country consuming 0.4 kilograms(14 ounces 盎司)of tea leaves per person a year compared with 0.36 kilograms (12.7 ounces) in 2007 according to the United Nations,as people switch away from soda,milk and fruit drinks.
Scientists are beginning to look into just how tea might affect mood and cognition.Specifically,they're investigating whether its relaxing and refreshing effects are a direct biological outcome of the compounds in tea or whether they come from the context in which the drink is consumed-preparing your tea,choosing your favorite cup and sitting down for a brief break from the wjye.aild.Or both.
Drinking green tea has been found to improve brain function in healthy people,said Stefan Borgward,chair and director of the department of psychiatry and psychotherapy at the University of Lubeck,Germany.
In a 2014 study,he gave one or two cups of green tea to 12 healthy volunteers and imaged their brains to analyze changes in connectivity inside certain brain regions.
"We noticed an increased connectivity in regions of the brain associated with working memory," he said via email.
And a 2017 review of more than 100 studies he coauthored found that green tea can impact the brain in three ways:It can influence psychopathological state such as reducing anxiety;cognition by benefiting memory and attention;and brain function,specifically memory.
That review concluded that "it would be desirable" for more Westerners to consume at least 100 milliliters (3.3 fluid ounces) of green tea each day "to protect neurocognitive(神經(jīng)認(rèn)知)function."
However,Borgward,cautioned that the effects aren't large,and the evidence is mainly provided by small-scale studies.

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."
(1)What's the purpose of the first paragraph?

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 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.
