With intelligent systems and new-age transit networks,life in the big cities will likely be happier and more efficient.
   After all,more than 60 percent of the world's population is expected to live in cities by 2050,according to a UN report.The answer to making these cities more livable for so many people lies in creating "smart" cities.These cities will use 5 G networks and the "internet of things"(IoT)to make everyday life safer and more convenient.Some cities are already using smart technology to improve the lives of residents.
   But what exactly does a smart city do?In the United States cities of Boston and Baltimore,smart trash cans can sense how full they are and inform cleaning workers when they need to be emptied.In Amsterdam,the Netherlands,traffic flow and energy usage are monitored and adjusted according to real-time data gathered from sensors(傳感器) around the city.And in Copenhagen,Denmark,a smart bike system allows riders to check on air quality and traffic condition as they ride.
   Smart cities will be interactive,allowing their residents to feel like they're truly shaping their environment,instead of merely existing in it. "One of the most important reasons to have a smart city is that we can actually communicate with our environment in a way that we never have in the past," said Mrinalini Ingram,head of a telecom company.
   "Smart cities will also allow us to save resources." said Mrinalini Ingram. "By using sensors and 5 G networks to monitor the use of water,gas and electricity,city managers can figure out how to distribute and save these resources more efficiently.Emissions of carbon dioxide and other air pollutants can be more closely monitored in smart cities as well."
   Of course,it will take time and money to turn our current cities into the smart cities of the future.But as we've already seen,more cities around the world are already adopting smart technology in small ways.China,for instance,is making investments in big cities like Shanghai and Guangzhou to make them "smarter".It won't be long until even more cities start to develop their own smart infrastructure(基礎設施).

C
C

A.The rapid progress in 5 G networks.
B.The marked increase in world population.

(2)How does the writer illustrate the way smart cities work?

(3)What can we learn from Mrinalini Ingram about smart cities?
B
B

A.People will be able to make the most of our environment at will.
B.Resources can be saved by keeping track of how they are used.
C.People will be better aware of environmental protection.
D.Air pollution will be stopped in its track.
(4)What is the author's attitude toward smart cities?

  • 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.

  • 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.
