Many drivers dream of the day when they can sit back while their car drives itself.While several companies are working hard to make it a reality,self-driving cars still face many problems.
Google was one of the first to get into this industry.It has been developing self-driving cars since 2009,and its new driverless car is called Firefly.
The two-seater car has a cute,round shape.Its front end looks like a friendly face:The"eyes"are headlights,the"nose"is a laser sensor and radar.
Another group of radars,lasers and cameras sits on top of the roof and gives the cars a 360-degree"view".They are linked to computer software that can identify people,cars,road signs,and traffic lights,and thus tell the car to make turns and stops.
But the driverless car is only a"fair weather friend",the Daily Mail commented.
According to the MIT Technology Review,the current driverless cars can't react like a human driver.They can't drive in heavy rain or snow.
Chris Urmson,director of the Google car team,said that this is because the detection technology is not yet good enough to separate certain objects from weather conditions.
In the cars'"eyes",raindrops and snowflakes are the same as rocks,and cars stop for them.
But if the manhole ahead is uncovered,they drive over it without hesitation.
Also,if a police officer waves at the side of the road to ask traffic to stop,the cars cannot understand them.
Despite all these problems,Urmson said driverless cars will"happen more quickly than people think"-perhaps as soon as in five years' time.
But even at that time,driverless cars won't be truly"driverless".
In the US,driverless cars are only allowed on roads in certain states if someone sits in the driver's seat.
European countries,Mexico,Chile,Brazil,and Russia follow the United Nations Convention (公約) on Road Traffic.The convention used to say:"Every driver shall at all times be able to control his vehicle or to guide his animals."A change was agreed in May,allowing a car to drive itself as long as a driver is in the car and able to take the wheel at any time.

B.They look completely different from normal cars.
C.It is illegal for them to drive on roads according to the United Nations Convention on road traffic.

(2)According to the article,the current driverless cars stop whenCC.
A.it is thundering

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?

(3)What happened during the Golden Years of Chocolate?

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.
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.
