Ⅰ.阅读理解
A
Have you ever fancied a tennis lesson from one of the world’s greatest tennis players at your
local court?
This dream came true for two young players，who got to train with 20-year-old superstar
Emma Raducanu after she appeared as a hologram(全息图)—a photographic recording of the
image.While Sam Clague,14，and T’nae Diamond Paisley,12，were both in London，the
British number one was in Abu Dhabi.
During the world’s first holographic lesson，Ms Raducanu’s avatar(头像) appeared to
feed balls to the players and gave live feedback on their shots，like ‘that was fast and there was
lots of topspin on that’．Even Sam said he thought she had been prerecorded at first until she
spoke with him directly.
Their holographic training session offers a glimpse into how advancing technology could
revolutionize tennis coaching，according to Dr Ian Pearson.
Dr Pearson thinks that mixed reality headsets will soon allow tennis players to feel they are
playing in unusual virtual environments，like on a space station or the middle of a lake.Through
5G，the future of tennis will see increased interaction between real-life tennis courts and the rich
imagination we see in computer games—playing whenever，wherever and whoever you want.
Full sensory virtual reality could even place the viewer inside the tennis player’s shoes in
real time.Dr Pearson said：“By 2030，with active skin technology，the playing styles and even
the sensations of top-level players could be captured，so that anyone could experience how it
actually felt to play that game through full sensory virtual reality.”
Finally，sportswear made from smart materials could allow for a digital coach powered by
artificial intelligence(AI) to provide feedback on a player’s form.Dr Pearson said ：“AI-
controlled suits made from smart materials，such as fabrics with sensors，can help players find
the perfect stroke when hitting or returning a serve by quickly learning the muscle memory of a
flawless forehand.Using direct feedback from friendly virtual AI coaches ，new players can
develop and learn much more quickly.”
1．What did Ms Raducanu do in the first holographic lesson?
A．Give players a real-time guidance.
B．Require players to follow her shots.

A．Increase their imagination of sports.
B．Take the place of top level players.
C．Experience the feeling of players on the spot.
D．Have a sense of playing in an unusual place.
3．What’s Dr Pearson’s attitude towards virtual AI coaches?
A．Critical. B．Skeptical. C．Careful. D．Favorable.
4．What might be the best title for the text?
A．The Future of Coaching B．The Threat from AI to Coaches
C．The First Live Coaching Online D．The Appearance of Digital Coaches

Geo-tracking apps such as Find My Kids and Google Family Link are fast growing in
popularity，handing parents powers to monitor their children.But how are the latter experiencing
what previous generations might have labelled as an invasion of their privacy? Could these devices
even hurt youths’ sense of independence?
We set out to answer these questions in our research，which involved a series of one-on-one
interviews with parents who geo-tracked their children，and teenagers who were geo-tracked.
Overall，the parents who took part in our survey claimed they were driven to use these apps
not by nosiness(多管闲事)，but a sense of care in the face of what they perceived as dangerous or
uncertain environments.Knowing a child’s geographical position cannot guarantee their safety
when faced with an incident in real time，but checking where they are can help ease parental
fears.Other parents surveyed admitted to monitoring their children only in the case of unanswered
phone calls or unfulfilled requests.Rather than a systematic method of monitoring，geo-tracking
acted as a “last resort” option after parents failed to reach their children.
While some teenagers were sympathetic to their parents’ anxieties，most of them perceived
the use of geo-tracking apps as an invasion of their privacy.When seen as a tool to contact，geo-
tracking appeared to be quite well accepted by them in our survey.However，most teenagers in our
sample were worried about their parents’ use of monitoring apps.
Geo-tracking is not without its ill effect on family relationships.Xavier，for instance，said
that discovering he was being tracked has profoundly weakened the trust between him and his
father.Furthermore，tensions among parents and children may also arise，thus widening the gap
between them.Geographical monitoring also directly challenges young people’s need to go into
the world independently，both holding back teenage autonomy and generating tensions in parent-
child relationships.
5．Why are the two questions raised for geo-tracking apps in paragraph 1?
A．To display their function.
B．To indicate their intelligence.C．To describe parents’ magic power.
D．To show the worry about privacy.
6．What makes parents adopt geo-tracking apps to monitor their kids?
A．Their desire to monitor their kids.
B．Their eagerness to reach their kids.
C．Their concern for their kids’ safety.
D．Their curiosity about their kids’ life.
7．What is most teenagers’ attitude towards the monitoring from apps?
A．Mixed. B．Confused. C．Indifferent. D．Critical.
8．What is the impact of geo-tracking on family ties?
A．It can make children more dependent.
B．It may badly influence family relationship.
C．It may relieve the tension within the family.
D．It can increase children’s trust in their parents.
Ⅱ.七选五
Facial recognition is a technology that uses distinguishable facial features to identify a
person.__1__ It may allow you to unlock your phone，go through security at the airport，and
purchase products at stores.
__2__ The police use the technology to uncover criminals or to find missing children or
seniors.Airports are increasingly adding facial recognition technology to security
checkpoints.When people know they are being watched，they are less likely to commit crimes.So
using facial recognition technology could prevent crime.
Another advantage is that，since there is no contact required for facial recognition like there
is with fingerprinting or other security measures，facial recognition offers a quick，automatic，
and seamless contact experience.__3__
The biggest drawback for facial recognition technology in most people’s opinions is the
threat to an individual’s privacy.In fact，several cities have considered or will ban real-time
facial recognition observation used by law enforcement agencies.__4__ It’s just not allowing the
government bodies to use live facial recognition software.
In addition，there are issues that need to be resolved when a person changes appearance or
the camera angle isn’t quite right.However，it’s dramatically improving now，according to
independent tests by a U．S.research institute.__5__
In order to benefit from the positive aspects of facial recognition，our society is going to have
to work through some significant challenges to our privacy and civil liberties.
A．Today，it is widely used in various aspects of life.
B．But sales organizations can still use it at certain times.
C．It has got 20 times better at finding a match in a database.D．So，no other security measures give you a similar experience.
E．There is nothing such as a key or ID that can be lost or stolen.
F．But police can still use devices such as Nest cameras to find criminals.
G．One of the major advantages of facial recognition is safety and security.

“Tiki！” I yelled.
Our little white dog Tiki had slipped out the door earlier that evening while I was carrying
groceries into the house.Now I was searching the neighborhood with my seven-year-old son，
Jordan，and my three-year-old daughter，Julia，trying to find him.
The last few months had been difficult.After losing my husband，I could no longer afford our
house in New York.The kids and I moved in northern Indiana,150 miles away from the city.Change
was easier for Julia at her age，but Jordan missed his friends and his old school.Losing his
childhood dog was the last thing he needed.
We called out Tiki’s name and knocked on neighbors’ doors until it was too dark to see.We
were forced to return home empty-handed.
“Mom，it’s all new here.What if Tiki can’t find our house？” asked Jordan.
“It’s okay，” I said.“He’s wearing his collar and dog tag，so if someone finds him，
they’ll call me，and we’ll get him back.” It was at that moment that I realized with horror that
Tiki’s tag listed our address and phone number in New York.If someone found him，they’d
have no way to reach me.
I kept asking around to see if anyone had spotted him.But after two weeks，I was beginning
to lose hope.
The kids were upset，especially Jordan.One afternoon，I found him crying in his room.“At
school，we had to write about our wishes，” he said.“I wrote，‘I wish my dog would comehome.’ Mrs Rush hung our papers in the hallway(走廊)．Every time I see my paper，I feel
sad.” My heart broke for him.
So later that week，when he put on an old T-shirt from his old school back in New York，
something told me to just let him do it.When he got home that afternoon，he told me the school
librarian had asked him about his T-shirt.“I told him that we just moved here from New York，”
said Jordan.
