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.Each year on Halloween,children look forward to trick-or-treating (不請客就搗亂) for candies.But for some kids,eating Halloween candies can be dangerous.
       That's because one out of every 13 kids in the Us have a food allergy(過敏癥).They are allergic to ingredients(成分)in many Halloween candies,such as peanuts,tree nuts,milk,eggs,and beans.If they eat these foods,they will get sick or even die.
       "I had to throw away all my candies with tears," eight-year-old Conlen said.Conlen is allergic to peanuts,tree nuts,and dairy.Twelve-year-old Kylie is allergic to peanuts and tree nuts.She has been trick-or-treating only twice. "I brought my candies home and gave them to the neighbors," Kylie said. "It felt terrible."
       But this year,Conlen,Kylie and other kids with food allergies will have a chance for a happy Halloween.That's because nearly 100,000 households across the US have promised to take part in the Teal Pumpkin Project(TPP),which was started last year by Food Allergy Research & Education(FARE).FARE is an organization that works to improve the lives of people with food allergies.Through the project,the households agree to have nonfood items for trick-or-treaters,including trinkets(小飾品) and toys.
       To take part in the project,people buy a teal(藍綠色) pumpkin or paint a pumpkin teal and place it in front of their house.The painted pumpkins let trick-or-treaters know that nonfood items are available there.The households also add their home addresses to an online map,making it easier for trick-or-treaters to find them.
       Kylie loves the idea."The TPP makes Halloween fun and safe," she said."It makes me feel like a normal kid,and it makes everyone feel included."

    (1)To Conlen and Kylie,the past Halloween were

    A.upsetting and dangerous
    B.interesting and special

    (2)According to the passage,we know that FARE

    A.helps people with food allergies recover
    B.helps the households take part in the TPP
    C.takes action to change kids' bad eating habits
    D.helps kids with food allergies have a happy Halloween
    (3)The households help kids with food allergies by

    A.giving them teal pumpkins as gifts
    B.offering them all kinds of food except candies
    C.providing them with trinkets and toys as treats
    D.asking them for home addresses and sending them gifts
    (4)Where is the passage most probably taken from?

    A.A magazine about the history of festivals.
    B.A news report on cultures and customs.
    C.An advertisement for an organization.
    D.A research paper on kid's health.

  • 3.Besides the excitement of travel,one reason to study abroad is that you will experience new customs,holidays,foods,art,music,and politics first-hand.
       "I learned the language and am now fluent,but perhaps what's more important is how much I learned about cultures,people,and myself.I learned this from the viewpoint of an active member of the community and my host family,not from the tourist's point of view," says Andrew,who studied in Poitiers,France.
       Another reason for studying abroad is that you'll gain self-confidence.Christina studied in Caracas,Venezuela,a city of more than 3 million people and a huge change from her hometown of 35,000!Christina says she learned how to better stand up for herself and her beliefs and to express herself in another language.What could make you more confident than that?
       Living away from home can also help you adjust in the transition(過渡)to college and adulthood.Mathew says he returned from studying in Australia with confidence and a real interest in international affairs that made him different from his peers(同齡人). "After having gone abroad in high school,I found the transition to college a breeze—moving 560 miles from home didn't seem particularly frightening after having lived thousands of miles away."
       Most of all,it's fun while you're studying in a different learning environment.

    (1)What is the passage mainly about?

    A.Learning a language.

    (2)What did Andrew pay special attention to while studying abroad?

    A.Host families.
    B.The foreign cultures.

    D.Community problems.
    (3)According to the example of Christina,what do we know about studying abroad?

    B.It can offer us opportunities.
    C.It can increase our knowledge.
    D.It can build our confidence.
    (4)What do the underlined words "a breeze" in paragraph 4 probably refer to?
