Do you need to throw your smartphone away to live your best life? Not necessarily, according to researchers from Ruhr-Universität Bochum who suggest that we could all benefit from cutting down on screen time — just only a little bit time.

On average, we spend more than three hours a day on our smartphone screens. Between social media, news feeds, endless video games, and an app for pretty much everything else, there’s always something to draw our attention. In recent years, studies have blamed(责备) smartphones for modern problems ranging from rising anxiety rates to neck pain. It begs the question: Are people all really better off turning back to landlines(座机)?

“The smartphone is both a blessing and a curse,” says study leader Dr. Julia Brailovskaia, whose team set out to answer that question by gathering together 619 volunteers, hoping to know how much the smartphone is good for us. 200 people put their smartphones completely aside for a week; 226 reduced the amount of time they used the device by one hour a day; 193 people didn’t change anything in their behavior.

Researchers interviewed each person about both their overall lifestyle habits and well-being four months later after the experimental week ended. “We found that both completely giving up the smartphone and reducing its daily use by one hour had positive effects on the well-being of the participants(参与者),” as Brailovskaia sums up the upshots. Notably, changing their smartphone habits for just one week appeared to produce lasting outcomes to the subjects(实验对象). Even four months afterward, participants who were told to avoid using their smartphones totally were using their phones for an average of 38 minutes less per day.

Meanwhile, the “one hour less” group were using their phones as much as 45 minutes less per day after four months. This group also showed improved life satisfaction, more exercise, and less depression(沮丧).

“It’s not necessary to completely give up the smartphone to feel better,” Brailovskaia concludes.

1. What’s the purpose of Paragraph 2?
A.To stress the benefits of smartphones.
B.To state disadvantages of the experiment.
C.To explain why the experiment was done.
D.To answer the question on the smartphones.
2. What did the researchers do to the volunteers before testing them?
A.They trained them.
B.They interviewed them.
C.They gave them a physical exam.
D.They divided them into 3 groups.
3. What does the underlined word “upshots” in Paragraph 4 mean?
A.purposeB.resultsC.reasonsD.doubts
4. What is the text mainly about?
A.Fewer smartphones, more well-being.
B.No smartphone use is the best policy.
C.Smartphones are a part of our lives.
D.A small smartphone, two big sides.

【推荐2】You are given many opportunities in life to choose to be a victim or creator. When you choose to be a victim, the world is a cold and difficult place.     1     “They” are wrong and bad, and life is terrible as long as "they" are around. Or you may blame yourself for all your problems, thus internalizing (内化) your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others.

    2    They know there are individuals who might like to control their lives, but they don't let this get in the way. They know they have their weaknesses, yet they don't blame themselves when they fail.     3    They believe their dance with each sacred (神圣的) moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.

Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish (沉溺) in anger, guilt, and other emotions that cause others — and even themselves — to feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them.     4    

In reality, all of us play the victim or the creator at various points in our the One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime.     5     He may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.

【推荐3】Ways to Be More Curious

Buried in the same daily routines and familiar surroundings, some people may lead an unhappy life.     1     It’s a desire to know how and why and a combination of intelligence and hunger for new things. Here are some tips on how to improve curiosity.

You should communicate with others. There is a to-do list in Leonardo da Vinci’s notebook. Out of the fifteen tasks on the list, at least eight involve consulting with others. Montaigne once wrote how traveling to different countries allows us to “polish our brains”.     2    

Why not visit a library? It allows us to meet other unexpected information. You can enter it without purpose.     3     And just follow your curiosity to explore unexpected knowledge. The more you explore, the greater your curiosity will be.

    4     With ideas stored in mind, you can mix and remix ideas and themes, making new findings and spotting unusual patterns, until a creative breakthrough is achieved, which strengthens your curiosity. Anyone stopping learning facts for himself because he can search online later is making himself stupid.

Don’t just focus on puzzles but on mysteries. Puzzles have clear answers. Once the missing information is found, it’s not a puzzle anymore, with curiosity fading away.     5     Because the answers often depend on a complex set of factors, both known and unknown. The most beautiful thing we can experience is mysteries. In the process of finding the answers, they are the source of curiosity.

A.Start to search for books you want or need.
B.Unlike puzzles, mysteries don’t need answers.
C.Mysteries have questions that can’t be answered clearly.
D.And that’s how Leonardo polished his brain to remain curious.
E.Allow books or things on the bookshelves freely to attract your eyes.
F.Always thinking of ideas rather than searching online plays an important part.
G.But we can achieve happiness and more meaning in life if we increase our curiosity.
