The Internet plays a big pan in human life.We use it for work and pleasure.We use it to lean a new language.We find advice on it.We use it to connect with family and friends.We use it to stay in touch with events we care about.The list goes on and on.
   As far as the Internet being a part of our lives,well that train has left the station.There is no going back to an Internet-free life.But can using the Internet too much be bad for our health?It might be,say researchers.A new study finds that heavy Internet use may be connected to high blood pressure in a young group:teenagers.
   The study results show that teens who spend at least 14 hours a week only online may cause high blood pressure,which makes your heart and blood vessels (血管)work too hard.Over time,this extra pressure increases your risk of a heart attack.High blood pressure can also cause heart and other diseases.
   The Henry Ford Hospital in Detroit,Michigan did the study.335 young people,from 14 to 17 years old,took part in it 134 of the teens were described as "heavy Internet users".And researchers found that out of these 134 teens,26 had high blood pressure.The researchers say the study is the first to connect heavy web use with high blood pressure.
   The lead researcher is Andrea Cassidy Bush row.She said,"Using the Internet is part of our dally life,but it shouldn't ruin us. " Ms.Cassidy Bushrow adds that it is important for teens to stop to have a rest regularly from their computers or smartphones and do some kind of physics-activity.She also suggests that parents shouldn't let their children use the Internet for more than two hours a day,five days a week.

  • 1.Every year,thousands of teenagers participate in programs at their local art museums.But do any of them remember their time at museum events later in life?A new report suggests that the answer is yes—and finds that arts-based museum programs are credited with changing the course of alumni's(畢業(yè)生的)lives,even years after the fact.
       The Whitney Museum of American Art,the Walker Art Center and the Museum of Contemporary Art,Los Angeles recently asked researchers to conduct a study to find out how effective their long-standing teen art programs really are.They involved over 300 former participants of four programs for teens that have been in existence since the 1990s.Alumni,whose current ages range from 18 to 36,were invited to find out how they viewed their participation years after the fact.
       Among the alumni surveyed,75 percent of them thought the teen art program experience had the most favorable impact on their own lives,beating the family,school and their neighborhoods.Nearly 55 percent thought that it was one of the most important experiences they'd ever had,regardless of age.And two-thirds said that they were often in situations where their experience in museums affected their actions or thoughts.
       It turns out that participating in art programs also helps keep teens enthusiastic about culture even after they reach adulthood:Ninety-six percent of participants had visited an art museum within the last two years,and 68 percent had visited an art museum five or more times within the last two years.Thirty-two percent of alumni work in the arts as adults.
       Though the study is the first of its kind to explore the impact of teen-specific art programs in museums,it reflects other research on the important benefits of engaging with the arts.A decade of surveys by the National Endowment for the Arts found that the childhood experience with the arts is significantly associated with people's income and educational attainments(成就)as adults.Other studies have linked arts education to everything from lower dropout rates to improvement in critical thinking skills.

    (1)Why were the researchers asked to conduct the study?

    A.To change the course of alumni's lives.
    B.To introduce the art museums.
    C.To find out how effective the long-standing teen art programs are.
    D.To invite people to participate in the art programs.
    (2)What do the figures in Paragraph 3 show?

    A.Students are more influenced by the family and school.
    B.Teen art programs in museums are highly beneficial.
    C.Many teens fail to realize the great value of art programs.
    D.Most experiences in museums are boring for today's teens.
    (3)What does Paragraph 4 tell us about art programs?

    A.They create adults who are culturally aware.
    B.They are intended to attract more adults.
    C.They are designed to support art museums.
    D.They provide many job opportunities for adults.
    (4)What do the studies mentioned in the last paragraph have in common?

    A.All suggest the need to improve museum programs.
    B.All show the growing popularity of art programs.
    C.All focus on the link between art and education.
    D.All prove the good effects of art education.

  • 2.The British are known for their sense of humour.However,it is often difficult for foreigners to understand their jokes.The main point to remember is that the British often use understatement.
       Understatement means saying less than you think or feel.For example,if someone gets very wet in a shower of rain,he might say. "It's a little damp(潮濕的)outside." Or,if someone is very impolite and shouts at another person,someone else might say, "She isn't exactly friendly." Understatement is often used in unpleasant situation or to make another person look silly.Understatement plays an important part in British humour.
       Another key to understanding British humour is that the British like to make fun of themselves as well as others.They often laugh about the silly and unpleasant things that happen to our everyday life when someone accidentally falls over in the street.They also like to make jokes about people from different classes of society.They like to make jokes about their accents,the way they dress and the way they behave.What's more,the British love to watch comedies about people who do not know how to behave in society.The comedy series Mr Bean is a good example of this kind of humour.Mr Bean is the character created by British actor Rowan Atkinson in 1990.
       Mr Bean doesn't talk often,and instead he uses his body movements and facial expressions to make people laugh.Perhaps what makes Mr Bean so funny is that he does things that adults in the real world cannot do.Mr Bean is popular in many countries around the world because you do not have to speak English to understand the humour.Because of this,many people have become familiar with the British sense of humour.

    A.The British often enlarge the fad.
    B.British jokes are connected with many different cultures.

  • 3.There is more of a connection between food and culture than you may think.On an individual level,we grow up eating the food of our culture.It becomes a part of who we are.Many associate food from our childhood with warm feelings and good memories and it ties us to our families,holding a special and personal value for us.Food from our family often becomes the comfort food we seek as adults in times of frustration and stress.
       On a large scale,traditional food is an important part of culture.It also operates as an expression of culture identity.Immigrants bring it wherever they go,and it is a symbol of pride for their culture and means of coping with homesickness.
       Many immigrants open their own restaurants and serve traditional dishes.However,the food does not remain exactly the same.Some materials needed to make traditional dishes may not be readily available,so the taste and flavor can be different from what they would prepare in their home countries.Additionally,immigrants do not only sell dishes to people from the same countries as them,but to people from different countries.Therefore,they have to make small changes about the original dishes to cater to a wider range of customers.Those changes can create new flavors that still keep the cultural significance of the dishes.
       We should embrace our heritage(傳統(tǒng))through our culture's food but also become more informed about other cultures by trying their food.It is important to remember that each dish has a special place in the culture to which it belongs,and is special to those who prepare it.Food is a window into culture,and it should be treated as such.

    (1)What's the function of food mentioned in the text?

    A.To help motivate homesickness.
    B.To show national identity.
    C.To reflect a country's history.

    A.The specific traditional food.
    B.The national culture.
    C.A traditional expression of food.
    D.The old-fashioned taste.
    (3)Why do some immigrants have to change the original dishes in their restaurant?

    A.To attach cultural importance to their dishes.
    B.To announce the beginning of their life on foreign soil.
    C.To make the dishes popular among customers.
    D.To present their own food culture in a new way.
    (4)What's the author's attitude towards different food cultures?
