电脑在我们的日常生活当中，给我们带来了许多方便。但是，也可能会给我们带来烦恼。一项研究发现，青少年过度使用因特网可能会导致高血压。 The Internet plays a big part in① human life.We use it for② work and pleasure.We use it to learn a new language.We find advice on it.We use it to connect with family and friends.We use it to stay in touch with③ events we care about④.The list goes on and on⑤. Well，that train has left the station.But can using the Internet too much be bad for⑥ our health? It might be，researchers say.A new study finds that heavy Internet use may be connected to high blood pressure (血压) in an unlikely group：teenagers. High blood pressure makes your heart and blood vessels (血管) work too hard.Over time⑦，this extra pressure increases your risk of a heart attack.High blood pressure can also cause heart and kidney (肾脏) disease.It is also closely linked to⑧ a brain disease. The Henry Ford Hospital in Detroit，Michigan did the study.335 young people，from 14 to 17 years old，took part in⑨ it.134 of the teens were described as⑩ “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 with⑪ high blood pressure.Other research has connected heavy Internet use with anxiety，depression and obesity (肥胖)． The lead researcher is Andrea CassidyBushrow.She said，“Using the Internet is part of ⑫ our daily life，but it shouldn’t ruin us.” Ms CassidyBushrow adds that it is important for teens to take regular breaks⑬ from their computers or smartphones and do some kind of physical activity⑭.She also suggests that parents limit (限制) their children’s use of the Internet to two hours a day，five days a week.
