单选题 British psychologists have found evidence of a link between excessive Internet use and depression, a research has shown.
Leeds University researchers, writing in the Psychopathology journal, said a small proportion of Interact users were classed as Internet addicts and that people in this group were more likely to be depressed than non-addicted users.
The article on the relationship between excessive Intemet use and depression, a questionnaire-based study of 1 319 young people and adults, used data gathered from respondents to links placed on UK-based social networking sites.
The respondents answered questions about how much time they spent on the Inventory-a series of questions designed to measure the severity of depression.
The six-page report, by the university's Institute of Psychological Sciences, said 18 of the people who completed the questionnaire were Interact addicts.
"Our research indicates that excessive Interact use is associated with depression, but what we don't know is which comes first--are depressed people drawn to the Interact or does the Interact cause depression.'?" the article's lead author, Dr. Catriona Morrison, said. "What is clear is that, for a small part of people, excessive use of the Internet could be a warning signal for depressive tendencies. "
The age range of all respondents was between 16 and 51 years, with a mean age of 21.24. The mean age of the 18 Internet addicts, 13 of whom were male and five female, was 18.3 years. By comparing the scale of depression within this group to that within a group of 18 non-addicted Intemet users, researchers found the Internet addicts had a higher incidence of moderate to severe depression than non-addicts. They also discovered that addicts spent proportionately more time browsing sexually pleasing websites, online gaming sites and online communities.
"This study reinforces the public speculation that over-engaging in websites that serve to replace normal social function might be linked to psychological disorders like depression and addiction," Morrison said. "We now need to consider the wider societal implications of this relationship and establish clearly the effects of excessive Interact use on mental health. /

单选题 Internet addicts are people who______
A. use the Intemet more than enough B. feel depressed when using the Internet
C. seldom connect to the Internet D. feel depressed without the Intemet

【正确答案】 A

【答案解析】根据题干中的Internet addicts定位到第2段。第2段是对第1段的解释说明，第2段提到的Intemetaddicts和depression之间的关系，由此对等关系可知Internet addicts应为“过度使用互联网的人”。因此，本题应选A。B和D都具有干扰性，因为这两项中提到的depressed来自原文，但depressed并非将某个网民归类为addict的标准，可见这两项没有说出addict的重点。

单选题 What was collected as data by the researchers?
A. The number of users of UK-based social networking sites.
B. Respondents' visits to UK-based social networking sites.
C. Links on UK-based social networking sites.
D. Respondents' answers to a questionnaire.

【正确答案】 D

【答案解析】定位到第3段。原文该段中提到这个研究是a questionnaire—based study，这表明研究者的数据来自“问卷调查”，即受访者填在问卷上的回答就是研究依赖的数据，由此可见，本题应选D。本题最具干扰性的是C，该选项的内容原文照搬自第3段段末，要注意的是，原文提到的links placed on UK-based social networking sites只是研究人员收集受访者的答卷的路径，这些links本身不是数据，因此，C选项纯属断章取义。

单选题 What is confirnmed by the study?
A. Depression leads to excessive use of the Intemet.
B. Depression results from excessive use of the Internet.
C. Excessive use of the Internet usually accompanies depression.
D. Excessive use of the Internet is usually prior to depression.

【正确答案】 C

【答案解析】定位到第6段。原文该段表明，研究找到沉迷网络与抑郁症两者相关，但它们孰因孰果却不明确，该段最后一句中的warning signal进一步说明了沉迷网络和抑郁症有关，对于沉迷网络的人，要小心他们同时患有抑郁症的可能，由此可见，沉迷网络的人通常伴有抑郁症，因此本题应选C。原文该段第1句but后的句子表明，研究人员不能确定沉迷网络和抑郁症出现的先后顺序或它们的因果关系，由此可见，其他三项的说法均与原文不符。

单选题 It is speculated by the public that online communities ______
A. can never replace normal social function B. are intended to replace normal social function
C. are associated with psychological disorders D. shouldn't take the blame for psychological disorders

【正确答案】 B

【答案解析】定位到第7段最后一句和最后一段第1句。最后一段第1句提到的“那些旨在取代正常吐交功能的网站”包括上一段最后一句提到的online communities，那么，很显然网上社区也是取代正常社交功能的网站，因此，B正确，其中are intended to是对serve to的同义改写。关于A，最后一段第1句提到“那些旨在取代正常社交功能的网站”时，websites后的定语从句提供的内容属于中性，即该定语从句没有表明这些网站是好是坏，也没有讨论它们是否“能”真正地取代正常的社交功能，A缺乏原文依据，故不能选。C是对最后一段第1句的might be linked to psychological disorders的近义改写，但原文中，这个谓语的主语为“过度使用…网站”，重点是“过度使用”，因此，那些网站本身与是否会造成心理失调无关，而原文也没有讨论这些网站本皇和心理失调之间的关系，C和D都与原文不符。

单选题 According to Dr. Catriona Morrison, the public speculation______
A. lacks scientific evidence B. helps clarify their study
C. toms out to be correct D. is worth further study

【正确答案】 C

【答案解析】定位到最后一段第1句。原文该句开头的reinforces(加强，进一步证实)表明Dr．Catfiona Morrison认为公众的想法是正确的，因此，本题应选C。Dr．Catriona Morrison没有从“科学性”去评论公众的猜想，因此A无原文依据；本文表明Dr．Catriona Morrison的研究加固了公众的猜想，而B说的是公众的猜想阐明了研究结果，显然与原文意思不符；D只是将第1句中的“公众猜想”和第2句中的“需要进一步思考”的问题硬扯在一起，属于随意拼凑。
