(2025·山东实验中学高三月考)》
The words“caring”and“empathetic(共情的)”
aren't ones normally associated with technology.
Yearsley,an Australian enterpriser who is expert in
artificial intelligence (AI),is trying to change that.
Yearsley is the founder of Akin,a robotics startup
that currently uses a tablet-based system to help users
manage the tasks related to home life,whether that's
planning meals or reminding you to pay your cell
phone bill.Current home devices made by Google or
Amazon or Apple use predictive AI to track patterns,
strengthen behaviors and manipulate (buying
decisions,some of which,she assumes,are
questionable or just unhealthy.
In contrast,the AI that she is developing will be
designed to run the human home,encouraging
healthful decisions such as taking a nightly walk,
refilling the fridge and supporting social interactions
like lunches or birthday celebrations with friends."It's
the hardest AI I have ever built for it's a complex
system,"Yearsley says.
Yearsley began developing the Akin technology in
2017,when she realized the need to better manage the
home is hugely ignored.Besides,she realized that
women unequally bear the burden of household work.
A United Nations report estimates that women do 2.6
times the amount of unpaid care and domestic work
that men do,or close to 30 hours per week in the US
alone.
While Yearsley pictures an army of robots
someday helping with routine homemade tasks,the
first display for Akin will take time and money.Akin
has received some early seed money from a handful of
investors,and was recently selected as a finalist for
tech giant LG Nova's Mission for the Future program,
an annual challenge that seeks to identify businesses
having potential to improve life and lead society into
the future.
1.What might the Akin's AI system suggest?
A.Consuming more drinks to enjoy yourself.
B.Staying up late working to make more money.
C.Spending more time staying with your family.
D.Purchasing products that may attract you.

Confirmation bias refers to people's tendency to
seek out information that supports their existing
beliefs.While it's usually subconscious,its impacts
are significant.It can cloud people's judgement and
decision-making processes.
One explanation for confirmation bias is that it is
an efficient way to process information.Humans are
constantly fed with information and cannot possibly
take the time to carefully process each piece.It is
adaptive for humans to rely on subconscious,automatic
judgements that contribute to the efficiency.Another
reason why people show confirmation bias is to protect
their self-worth.People like to feel good about
themselves,and discovering a belief they highly value
is incorrect makes them feel bad about themselves.
Therefore,confirmation bias will encourage them to
disregard the information contrary to their belief.
Researches show that confirmation bias is strong
and widespread.In studies examining my-side bias,
people were able to generate and remember more
reasons supporting their side of a controversial issue
than the opposing side.Only when a researcher directly
asked people to generate arguments against their own
beliefs were they able to do so.It is not that people are
incapable of generating arguments that are contrary to
必修第三册
their beliefs,but,rather,people are not motivated to
do so.
Confirmation bias also surfaces in interpersonal
communication.When interacting with people who
perceivers think have certain personalities,the
perceivers will ask questions that are biased toward
supporting the perceivers'beliefs.If a new roommate
is expected to be friendly and outgoing,Maria may ask
her if she likes to go to parties rather than asking if she
often studies in the library.
Confirmation bias may lead to incomplete and
misinterpreted understanding of an issue or topic,as
crucial information may be overlooked or dismissed.
Thus,to avoid it,people are supposed to diversify the
sources of information accessed as seeking multiple
perspectives brings a broader understanding of the
subject matter and allows for well-rounded decision-
making.Another way is to actively challenge the bias
by questioning assumptions and relying on evidence
rather than personal opinions,which helps us
consciously recognize informational biases and
minimize their impact.
5.Why do people show confirmation bias?
(
A.To help maintain their dignity.
B.To prevent shallow judgements.
C.To handle complex information.
D.To develop their logical reasoning.
6.What did the studies in Paragraph 3 find?
(
A.People couldn't produce arguments against their
belief.
B.Information supporting people's belief often won
preference.
C.It took considerable motivation to face controversial
issues.
D.People focused on information concerning the
opposing side.
7.How does the writer illustrate confirmation bias in
communication?
A.By making comparison.
B.By giving an example.
C.By introducing a study.
D.By defining a concept.
8.What is the passage mainly about?
A.The role of my-side bias in enhancing people's
own beliefs.
B.The effects of information overload on decision-
making process.
C.The impact of confirmation bias on interpersonal
communication.

(2024·广东广州模拟)
Physicist and Nobel Prize winner Richard
Feynman developed a clever learning method known as
the Feynman Technique.It involves explaining what
you're learning to others.By teaching what you've
learned from memory,you engage in active recall.
1()It also ensures that you understand the topic,
because you can only explain an idea if you truly
understand it.The technique consists of four repeatable
steps.
To begin,choose a concept or topic you wish to
fully understand.2()The more interested you
are,the faster you'll grasp it.Moreover,a personally
interesting topic will keep you motivated and engaged.
3()Write notes and explain it in a way that
makes sense to a five-year-old.If you'd rather avoid
actually teaching someone,you can just teach it to an
imaginary audience.But it works much better if you
use a real person.They'll be able to let you know
when something isn't clear.
While teaching you may discover gaps in your
understanding.4()Review your notes,reread
books,or seek external help to ensure you have a
complete understanding of the context before moving
forward.
Now that you fully grasp the concept,test your
understanding by trying to teach it to another person.
This will help you identify any remaining areas of
uncertainty you need to revisit.
The Feynman Technique is a great way for kids
and grown-ups to learn.5()You need to actively
think about the problem instead of passively reading or
listening to someone else.However,with great efforts
in mastering this method,you'll see your learning
results improve quicker than ever before.
A.It is mentally demanding.
B.This helps the information stick in your mind better.
C.Teach it to a five-year-old,who would give you
direct feedback.
D.Your curiosity about it will determine the pace of
your learning.
E.Once you have chosen a topic,you can teach it to
someone else.
F.Active engagement plays a key role in promoting
deeper learning.
G.When this happens,refer back to the original
material for the missing pieces.
