Question

Internet time tied to teen depression(抑郁) symptoms

Spending time online is normal behaviour for teenagers. But too much Internet use by teens —or too little, for that matter —might be related to depression, 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. Instead, the researchers say that both heavy Internet use, and non-use, could serve as signals 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 7,200 individuals aged 16 to 20 about 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” that gauge(判定) 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 male teens, 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 86 percent greater chance of depression, while non-users had a 46 percent greater likelihood compared to regular users.

That was with factors like family income and any chronic health problems taken into account.

Since teenagers typically go online to contact with friends, the researchers speculate(推测) that those who are never online may be more socially isolated.

【解析】

这是一篇说明文。本文阐述调查研究证明：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。

1.细节理解题。根据第四段第一句“Those who were online more than two hours per day were considered heavy’ Internet users ...”可知，每天上网时间超过两小时的人被视为“过度上网者”。 故选A。

2.推理判断题。根据第三段中的“surveyed 7,200 individuals aged 16 to 20 about their Internet use”和接下来的研究结果叙述可知，Michaud博士和他的同事研究的目的是了解因特网的使用和抑郁症的关系。故选D。

3.词义猜测题。根据前句Since teenagers typically go online to contact with friends “青少年上网主要是为了与朋友们联系”可知，“那些从来不上网的青少年可能更孤立自闭”，故用 separated (分离的，单独的)最合适。 故选C。

4.推理判断题。根据本段中的Among girls, heavy Internet users had an 86 percent greater chance of depression, while non-users had a 46 percent greater likelihood compared to regular users.可知，女孩当中过度上网者患抑郁症的可能性比正常上网者高86%，从而可以推断出，在女孩中，重度上网者比正常上网者更容易患抑郁症。故选B。
