　　Technology is everywhere. We see it any place we go and， in fact， almost all of us carry some piece oftechnology with us every time we leave the house. What I always forget， though， is just how useful andpowerful technology can be when we want to help others.

　　There is not a single room in my house that does not have some electronic devices(设备) lying around init. Whenever I am at home， I am almost always using at least one electronic device. If you walked into myliving room on any given day， you would find that， first， I have the television on. At the same time， I usuallyhave my laptop resting on my knee， or I will be using my mobile phone， Even when i'm not at home I amalways using my phone， and at work or in cafes， I sit down and connect to the local wireless network on myipcop.

　　I must say that I waste a lot of time on the computer and the time I spend on it could be much betterspent if I were to take up a little online volunteering

　　The technology we carry about everywhere can have a great power to do good for the world and to helpothers and recently I discovered just how much online volunteering there is to do in the world. From usingyour language skills to do translations， to developing and managing projects and helping with IT work， thereis so much that so many people can do to help people in their own countries and across the world. The UnitedNations， in fact， has a huge page with "Volunteers Recruited" on its website.

　　This work can support the poor and help charities who cannot pay for staff. Many organizations onlyrequire you to work an hour a week-some even less. And the support provided by online volunteers can reallyhelp make a difference to those in need.

　　A. uses technology a lot B. works in a cafe

　　C. is a computer engineer D. likes modern music

　　【答案】27. A 28. B 29. D 30. C

　　【解析】科学技术已经渗透进了我们的生活，我们每天都在使用这些科技带来的方便中。但作者认为我们应该利用这些先进的技术去帮助别人，这样才能体现出这些科技的力量。

　　27. 细节理解题。题目问到的是短文第二段，仔细阅读这一段我们可以知道，这一段的第一句话是该段的中心句，根据这句话There is not a single room in my house that does not have some electronic devices(设备) lying around in it.的意思可知，在作者的家里，没有一个房间里是没有电子设备的，也就是说作者使用非常多的电子设备，下面的文字作者举例来说明，如television, laptop, mobile phone等，故应选A。

　　28. 词义猜测题。根据该段中I discovered just how much online volunteering there is to do in the world.可知，作者发现在网上有很多在线志愿活动，而这句话说的就是联合国在网上招募志愿者的一个网站，由此我们可以知道划线这个单词应该是“招聘”的意思，与wanted同义，故选B。

　　29.细节理解题。根据第三段中I must say that I waste a lot of time on the computer and the time I spend on it could be much betterspent if I were to take up a little online volunteering以及下一段中的The technology we carry about everywhere can have a great power to do good for the world and to help others可知，故选D。

　　30. 主旨大意题。这篇短文开头部分作者讲述了我们周围无处不在使用着科学技术，短文的第一段中What I always forget， though， is just how useful and powerful technology can be when we want to help others点明文章的主题，从短文的第三段开始，作者对文章主题进行展开论述，即我们应该利用这些技术去做一些在线的志愿者活动，去帮助别人，所以C选项Online volunteering在线志愿者活动这个题目能点明文章的主题，故选C。A选项Website Design网站设计;B选项Internet Organization在线组织;D选项Online Translation在线翻译，这几个选项都不符合文意。

　　这篇短文讲述的是现在我们应该利用我们周围无处不存在着先进的技术去帮助别人。短文主题明确、突出，线索也非常清楚，比较有利于学生们的做题。后面的题目设置包括细节理解、词义猜测和主旨大意题。细节题都可以在短文中寻找到相关信息去作答，例如第1小题，这个题目涉及的是短文第二段的内容， 因此我们只需要弄清楚第二段的大意就行，这一段的主题句是第一句话，根据这一句我们可以知道，这里作者介绍的是他家里的各种各样的电子设备，说明他在平时的生活中大量的使用了这些设备，故应选A。
