单选题 Do your children lie to you and their friends about their activities online? Do they feel empty, depressed and irritable when not at the computer? Do they have problems with school or work, yet they always seem to feel energized again when they are at the computers surfing the internet? If you answered "yes" to one or even more of the above questions, your children are suffering from internet addiction. The amount of time kids spend online is a source of headaches for many parents. At first, parents welcomed the Internet into their homes, believing they were opening up an exciting new world of educational opportunities for their children. But soon, to their disappointment, instead of using the Internet for homework or research, their kids were spending hours instant chatting with friends, playing online games or even talking to strangers in chat rooms, which is posing real dangers to the children.
Maintaining a healthy balance between entertainment media and other activities in children's lives has always been a challenge for parents. The Internet has made this challenge even more difficult. The engaging nature of Internet communications and interactive games means many children and teens have trouble controlling the time they spent online.
Unfortunately, parents and teachers do not realize that there is a problem until it becomes serious. To make it worse, Internet addiction is not widely recognized by the medical community. (Mental health practitioners continue to debate whether this behavior is an "addiction," with some preferring to identify it as "behavior control problems.
Children and young people can easily become "hooked" on online activities such as multi-user games, instant messaging with their pals and chat rooms. The children most easily influenced, according to the Computer-Addiction Services at Harvard Medical School, are those who are "lonely and bored or from families where nobody is at home to relate to after school."
Children who are unpopular or shy with peers are often attracted to the opportunities for creating new identities in online communities. Boys, in particular, are frequent users of online role-playing games, where they have new identities and interact with other players. Although playing these games with thousands of other users may appear to be a social activity, for the troubled child or teen, too much playing can further separate them from friends and peers.

单选题 Which one of the following is NOT mentioned as one of the activities children doing online that are giving parents headaches?

【正确答案】 B

【答案解析】[解析] 细节题；原文的首段就提出了家长发现孩子们日益陷入网络之中，他们从事的活动主要有“instant chatting with friends，playing online games or even talking to strangers in chat rooms”，对照选项，A、D和C这样的选项顺序是对原文信息的逐个改写，B选项貌似原文中提到的“posing real dangers to the children”这一个信息点，但是其主语却搞错了，原文是说“聊天室聊天会对孩子造成威胁”，而不是像选项中所说的那样“由于上网中病毒给电脑造成威胁”，该选项是在有意地曲解原文的意思。

单选题 What is the "challenge" the author is talking about in paragraph 2?

【正确答案】 D

【答案解析】[解析] 细节题；这里明确告诉我们是要考查原文第二段之中的challenge一词，通过句子的分析就可以解决这个问题，原文中有这样一句话“Maintaining a healthy balance between entertainment media and other activities in children's lives has always been a challenge for parents．”，这里的主语部分就是我们要寻找的答案，分析句子可以发现，主语的核心部分是 balance，要寻求一种平衡，一种在“娱乐媒介”和“其他活动”之间的平衡，D选项和这样的意思不谋而合。A和C选项是在曲解原文的意思，B选项的迷惑性相对较大，提到了网络游戏的问题，但从原文我们可以看到，这些因素的谓语部分是“made this challenge even more difficult”，也就是加重了这一问题，而不是问题本身。

单选题 What seems to make the situation of internet addiction worse?

【正确答案】 D

【答案解析】[解析] 细节题；题干的主体成分是“What makes the situation worse”从原文可以看到“To make it worse”这样的同义表达，所以我们需要找到的是和“Internet addiction is not widely recognized by the medical community．”具有类似含义的句子，选项中D具有这样的意思，为正确选项。A和原文中第三段首句的表达非常类似，但这不是文章中所说的导致问题恶化的因素，干扰性比较大。B和C都是利用原文的具体细节信息在借题发挥，他们分别在原文的“medical”和“behavior control problems”的基础上进行偏离文章内容的肆意发挥，均为干扰选项，要排除他们的难度不大。

单选题 Who seem to be the group of children that are more easily to get addicted with internet?

A、 Children who are popular among a lot of friends, because they need to communicate with them even when they are online.
B、 Children who come from big families since they can get the attention they desire but fail to get from real life.
C、 Children who are not welcome among peers since online communication and games can satisfy their needs in a way real life can not.
D、 Children who like to play basketball, football and other sports activities since online game can make all these more fascinating.

【正确答案】 C

【答案解析】[解析] 细节题；“The children most easily influenced，according to the Computer-Addiction Services at Harvard Medical School，are those who are“lonely and bored or from families where nobody is at home to relate to after school．”这句话是该题答案的参考出处，其主语部分就是我们题干的设问部分，而这个句子的后半部分的骨干在“those who are‘lonely and bored…’”部分，选项中的C符合这样的含义。其他选项均是在文章中的细枝末节的细节信息点处进行随意发挥改写。
