Computers，smartphones，and audio players are an essential part of students' everyday lives.That means that whenever students are doing homework，they are going to be faced with the problem of using their devices for purposes other than learning.Instead of concentrating on one task，they are performing multiple tasks.
According to the research by Larry Rosen，published in the journal Computers in Human Science，students spend up to 45% of their homework time on various tasks unrelated to their studies.Students often get distracted by their phones or use their laptops for unauthorized activities.Often，students think that they are able to multitask effectively，without sacrificing their studies.However，the research shows that it is true in only 5% of all cases.
But why do teenagers multitask？The answer is simple：multitasking makes us feel good.As the research indicates，the entertainment gained from secondary activities during studies makes learners feel better emotionally.
Watching TV or talking to your friends by email is pleasant and helps students fight boredom while doing homework or listening to a lecture they find boring.Another reason why students multitask is that they simply do not see the negative impact it has on their coursework.Teenagers often overrate their abilities.The seemingly tiny distractions，however，result in a constant need to switch focus and sort out information，injuring the brain by overuse and making the process inefficient.
However，the effects of multitasking are not entirely negative.The research conducted by HKU indicates that people who routinely multitask are able to use their senses in conjunction more easily.Other research also shows that multitasking has a positive effect on the ability to pass judgment and solve problems quickly and efficiently.

1．How to Learn from Your Regrets Regret's benefits don't come to us by chance.（1）
.Here are three steps you can take the next time you find yourself thinking carefully about your past missteps.
Kill the ghost（鬼魂）.
People often say their regrets keep coming to their mind.This suggests that regret is like a ghost.Bring your ghost out of the shadows by making a list of your regrets.Write down why each one still bothers you and its bad effects.（2）.
Forgive yourself.
（3），but sometimes you just can't stop blaming yourself.Perhaps you dropped out of school decades ago and are constantly calculating today how much money you would be making if you had pressed on to graduation.Now is the time to declare："I will not waste my life reliving a decision that cannot be changed."
Collect your diploma.
Regret is like a school run by human nature.If you never experienced regret，you would keep repeating the same behaviors that led you to miss opportunities. （4）.Next，list all the ways that you can invest in your own skills and improvement right now — and get started.
Regrets may hurt.（5），while trying to live without them is a lost opportunity to grow.Life is a journey full of pleasures and pains.To live it well and fully means learning from every bit of it，including the mistakes，and moving forward.
A.After you make a mistake，life moves on
B.Filling your mind with them is destructive
C.The ghost certainly doesn't rule a person's life
D.We have to seek them out on purpose to improve ourselves
E.You will find that a list is a lot less frightening than a ghost

G.If you let regret teach，you can note how you want to change your behavior發(fā)布：2025/1/1 17:0:1組卷：3引用：5難度：0.4 -
2．When faced with the decision to get out of bed or have a few more minutes of sleep，which do you choose？Believe it or not，that decision could make a world of difference in the rest of your day.
About 85 percent of Americans use an alarm clock to wake up in the mornings，according to sleep researcher Till Roennenber.And while there are no official numbers on snoozing（打盹），a quick survey of social media makes it clear that hitting the snooze button is a popular pastime.
As to how the snooze button will affect your day，scientists have mixed opinions.Some scientists think people who hit the snooze button in the mornings are actually clever，creative and happy while some said that hitting the snooze button will ruin your life，or at the very least your day. "I feel that hitting the snooze button has got to be one of the worst things that ever happened to human sleep，" researcher Jonathan Horowitz said. "The chances of you 'snoozing' and actually experiencing a meaningful rest are close to zero."
According to some sleep experts，when hitting the snooze button，you are in fact confusing your body and mind，and throwing yourself into a deep state of being sleepy.The body needs some time to wake up，so，when returning to what will be a light sleep for a brief period of time，you are putting your body back into a sleep mode before waking it again.At that point your body won't know what it wants，resulting in a sort of half awaken state.
If you really want to take advantage of an alarm clock，the key is to form a healthy sleep cycle.Focus your efforts on getting enough sleep each night and waking up at the same time each day so that when your alarm goes off you feel rested.
（1）What can we infer about hitting the snooze button from Paragraph 2？
A．People do it just for fun.
B．It is a common practice.
C．People take it seriously.
D．It is a bit childish.
（2）What do some sleep experts think of hitting the snooze button？
A．It is meaningful in the long term.
B．It makes people become lazy.
C．It brings us a sense of satisfaction.
D．It affects our body and mind.
（3）What's the author's suggestion on getting the best out of alarms？
A．Forming a good sleep habit.
B．Trying to relax ourselves.
C．Making use of willpower.
D．Using an extra alarm.
（4）What is the best title for the text？
A．Ways to keep refreshed in the morning.
B．The snooze button and people's character.
C．Should you rely on the snooze button？
D．How to avoid the light sleep mode？發(fā)布：2025/1/1 17:0:1組卷：2引用：4難度：0.6 -
3．The curb cut （下斜路緣）.It's a convenience that most of us rarely，if ever，notice.Yet，without it，daily life might be a lot harder—in more ways than one.Pushing a baby stroller onto the curb，skateboarding onto a sidewalk or taking a full grocery cart from the sidewalk to your car—all these tasks are easier because of the curb cut.
But it was created with a different purpose in mind.
It's hard to imagine today，but back in the 1970s，most sidewalks in the United States ended with a sharp drop-off.That was a big deal for people in wheelchairs because there were no ramps （斜坡） to help them move along city blocks without assistance.According to one disability rights leader，a six-inch curb "might as well have been Mount Everest".So，activists from Berkeley，California，who also needed wheelchairs，organized a campaign to create tiny ramps at intersections to help people dependent on wheels move up and down curbs independently.
I think about the "curb cut effect" a lot when working on issues around health equity （公平）.The first time I even heard about the curb cut was in a 2017 Stanford Social Innovation Review piece by PolicyLink CEO Angela Blackwell.Blackwell rightly noted that many people see equity "as a zero-sum game." Basically，that there is a "prejudiced societal suspicion that intentionally supporting one group hurts another." What the curb cut effect shows though，Blackwell said，is that "when society creates the circumstances that allow those who have been left behind to participate and contribute fully，everyone wins."
There are multiple examples of this principle at work.For example，investing in policies that create more living-wage jobs or increase the availability of affordable housing certainly benefits people in communities that have limited options.But，the action also empowers those people with opportunities for better health and the means to become contributing members of society—and that benefits everyone.Even the football huddle （圍成一團以秘密商討） was initially created to help deaf football players at Gallaudet College keep their game plans secret from opponents who could have read their sign language.Today，it's used by every team to shield the opponent from learning about game-winning strategies.
So，next time you cross the street，or roll your suitcase through a crosswalk or ride your bike directly onto a sidewalk—think about how much the curb cut，that change in design that broke down walls of exclusion for one group of people at a disadvantage，has helped not just that group，but all of us.
（1）By "might as well have been Mount Everest" （paragraph 3），the disability rights leader implies that a six-inch curb may become.
A．a(chǎn)s famous as the world's highest mountain
B．a(chǎn)n almost impassable barrier
C．a(chǎn) connection between people
D．a(chǎn) most unforgettable matter
（2）According to Angela Blackwell，many people believe that.
A．it's fair to give the disadvantaged more help than others
B．it's impossible to have everyone be treated equally
C．it's necessary to go all out to help the disabled
D．it's not worthwhile to promote health equity
（3）Which of the following examples best illustrates the "curb cut effect" principle？
A．Spaceflight designs are applied to life on earth.
B．Four great inventions of China spread to the west.
C．Christopher Columbus discovered the new world.
D．Classic literature got translated into many languages.
（4）What conclusion can be drawn from the passage？
A．Everyday items are originally invented for people with disabilities.
B．Everyone in a society should pursue what is in his or her interest.
C．A disability rights leader changed the life of his fellow men.
D．Caring for disadvantaged groups may finally benefit all.發(fā)布：2025/1/1 17:0:1組卷：8引用：3難度：0.3
