B(2025山东滨州二模)
When Loki,the golden retriever(寻回犬),entered our lives five years ago,we anticipated that he would assume the roles of tail-wagging family guardian and personal trainer.
Time has proved that not only does Loki fulfil all those functions,he’s also the family’s ultra-punctual alarm clock as well as stand-up comedian.But without doubt his most unexpected contribution to our household is that of peacemaker.
Now,Loki is the spiritual leader of our family.When we become irritated,such as when my wife mentions my weight,he always makes us stop arguing.Loki possesses a reliable warning system.As soon as our voices rise,he demands the restoration of harmony,first leaning his head on the leg of the instigator of the argument and staring at him or her with pleading eyes.If he fails,he will climb up and lick his or her neck affectionately,which usually works.Therefore,if we want to have a good argument,we have no choice but to leave home.
After 28 years of marriage,time hasn’t eased our hot temper,but Loki’s influence has.He has imposed his personality on us.He has also improved my well-being.When attached to a blood pressure monitor,I’ve watched my numbers head in the right direction when Loki lies next to me on the sofa.Scientists say stroking a dog can reduce blood pressure by as much as 10 percent.
As usual,the other day,just after daybreak,I found myself lying on the edge of the bed,pushed aside by Loki,which was lying on a down comforter,snoring(打鼾) intermittently.And it suddenly dawned on me that I spent more time sleeping alongside Loki than my wife.
Although Loki has the ability to mediate,he is particularly unable to convince Tracey to let me cross the threshold(门槛) at night due to my snoring.My weight is undoubtedly the cause.It’s time for him to step back up to his primary role,a personal e on,Loki.Let’s go for a run!
4.What was Loki originally expected to serve as according to the author
A.A peacemaker.
B.An alarm clock.
C.A spiritual leader.
D.A family guardian.
5.What might be Loki’s way to end the argument between the couple
A.Raising his voice.
B.Barking at the couple.
C.Interacting with the instigator.
D.Running away from home.
6.What can be inferred from the last three paragraphs
A.The author blames his weight problem on Loki.
B.Tracey doesn’t allow the author to go out at night.
C.Loki has a positive influence on the author’s health.
D.The author prefers sleeping alongside Loki to his wife.
7.What’s the tone of the passage
A.Relaxing. B.Critical.
C.Serious. D.Ironic.
C(2025湖南永州二模)
When we sleep,our brain is still actively processing the day’s experiences and integrating them with past memories.Previous studies have identified links between pupil(瞳孔) size and sleep state,as well as between sleep state and memory formation.However,it has been unclear how fresh memories are processed without blurring into old ones.For example,how do we learn to play the piano without forgetting how to ride a bike
Researchers at Cornell University addressed this question by attaching brain-scanning electrodes and tiny eye-tracking cameras to mice.They monitored the mice as they learned new tasks during the day,such as navigating a maze,and then observed them during sleep.(Fun fact:mice can sleep with their eyes open.)
The study revealed two distinct substages during non-rapid eye movement(NREM) sleep,a critical period for memory formation.One substage replayed new memories,coinciding with narrowed pupils.The other involved recalling older memories,marked by widened pupils.These stages alternated rapidly.The team also discovered that during the narrowed pupil stages,blocking sharp-wave ripples(SWRs) limited the mice’s ability to remember new information.
It is also found that the brain has an intermediate(中间的) period that separates new learning from old knowledge.The results suggest that the brain can multitask distinct cognitive processes during sleep to facilitate continuous learning without interference.It’s like new learning,old knowledge,new learning,old knowledge,shifting slowly throughout sleep.
The implications of the study are far-reaching:such a non-invasive means of monitoring brain function may help treat memory issues and boost memory,for example.The study also supports the hypothesis(假说) that human brains and computer systems may significantly forget old information.Catastrophic forgetting,known in AI,is an area where machines still lag behind biology.What’s more,the findings provide a potential solution for preventing catastrophic interference while enabling memory integration in both biological and artificial neural networks.
Despite the many similarities between human and mouse brains,similar studies need to be conducted in humans to verify these results.
8.What do researchers at Cornell University focus on
A.How pupil size is related to sleep state.
B.How people learn to perform new tasks.
C.How memories are kept without interference.
D.How sleep state is connected with memory formation.
9.What is the finding of the study
A.Blocking SWRs removes old memories.
B.The brain processes new memories first.
C.Widened pupils are associated with replaying new memories.
D.A transitional stage distinguishes old memories from new ones.
10.What is the implication of the study
A.It provides an invasive solution to memory study.
B.It helps avoid large-scale interference and integrate memory.
C.It denies that brains and computers may forget information dramatically.
D.It supports that machines perform better in catastrophic forgetting than brains.
11.Which of the following can be a suitable title for the text
A.Code of Memory Integration in Sleep
B.Role of Sleep in Memory and Learning
C.Pupil Size:A Window into Human Brain
D.A Breakthrough:How Mice Sleep with Eyes Open

Motivation is the stimulus for you to take positive action.Motivation comes in two types.The first is self-motivation,which comes from within ourselves.The second is motivation from external sources.
Many of us have a dream that we would love to achieve.Our dream can be something we want to accomplish in our professional life,our personal life,or even in our social life.　12　 Perhaps we want to set up our own business,become a best-selling author,or maybe a social-media influencer.In our personal lives,we might seek to enter a top university,get married,have children,or move to a better neighborhood.We might be eager to travel or enlarge our pool of friends.　13　
Having dreams is fine,but realizing those dreams is even better.Achieving dreams requires determination,single-mindedness,courage,and commitment.　14　 As we gain experience and knowledge,we will become more confident.
Above all,we must feel motivated to begin the journey to pursue our dreams and remain motivated.　15　 Small obstacles can take on huge proportions if you lose your motivation,and soon you find you have given up on your dream.
　16　 A whole industry has grown up dedicated to motivating people.Motivational speakers outline their recipes for success.There are videos,books,documentaries,and online courses available to anyone seeking motivation.Just by having a dream,we tend to be motivated to try to achieve it successfully.
A.How,therefore,do we get and stay motivated
B.We’ll need to work hard and not be afraid to fail.
C.We might seek a better job or getting promoted.
D.Then,what should we do next after having a dream
E.So it’s crucial to make a thorough plan before acting.
F.The list is indeed long,and some pursue more in our lives.
G.Staying motivated is hard,especially with frequent setbacks.
