1.Spending time online is normal behavior for teenagers.But too much Internet use by teens-or too little,for that matter-might be related to depression (抑郁),a new study finds.
The findings,reported in the Journal of Pediatrics,do not mean that the Internet is to blame.For one,teens in the study who spent no time online were also at increased risk of depression symptoms (症状).Instead,the researchers say that both heavy Internet use,and non-use,could show that a teenager is having a hard time.
For the study,Dr.Pierre-Andre Michaud and his colleagues at the University of Lausanne,Switzerland,surveyed 7,200individuals ages 16to 20about their Internet use.
Those who were online more than two hours per day were considered"heavy"Internet users,while those online anywhere from several times per week to two hours per day were considered"regular"users.
The teenagers also answered a number of health-related questions,including some standard questions about"depressive tendencies"(抑郁倾向) that show how often a person feels sad or hopeless.Compared with regular Internet users,the study found,kids who were heavy users or non-users were more likely to be depressed or very depressed.
Among boys,heavy users and non-users were both around one-third more likely to have a high depression score,compared to"regular"users.Among girls,heavy Internet users had an 86percent greater chance of depression,while non-users had a 46percent compared to regular users.
Since teenagers typically go online to connect with friends.The researches find that those who are never online may be more socially isolated.

分析 本文通过一次调查证明了,在年轻人中,重度互联网使用者和从不使用互联网的孩子都有抑郁倾向,从来不使用互联网的孩子甚至会被社会孤立.
解答 56.B推理判断题.根据文中第二段的原句For one,teens in the study who spent no time online were also at increased risk of depression symptoms (症状).可以得知从来不上网的年轻人有抑郁症状的风险也在增加.另外,倒数第二段中的原文Among boys,heavy users and non-users were both around one-third more likely to have a high depression score,compared to"regular"users.Among girls,heavy Internet users had an 86percent greater chance of depression,while non-users had a 46percent compared to regular users.这个实验证明了在男生中不上网的年轻人与正常使用互联网的人相比有三分之一有抑郁的表现,女生中百分之四十六.故选项B的描述正确.
57.A细节理解题.根据文中第四段中的原句while those online anywhere from several times per week to two hours per day were considered"regular"users.可以得知,那些每天上网两小时的人被称为"正常使用者".所以作者建议年轻人每周上网的时间要少于14小时.故选A.
58.D细节理解题.结合文中第三四五段的活动,Dr.Michaud 是想通过实验证明使用互联网时间的长短对年轻人的压力之间的关系.故D选项描述正确.
59.C词汇理解题.结合文中最后一段原句Since teenagers typically go online to connect with friends.The researches find that those who are never online may be more socially isolated.由于年轻人上网是为了与朋友联系,所以调查还发现那些从来不上网的孩子可能有被社会、社交孤立了.故isolated的意义等同于separate,表示孤立、分开.
