Teachers say the digital age has had a good influence - and a not-so-good influence - on this generation of American teenagers．More than 2,000 teachers took an online survey．Three-quarters of the teachers said the Internet and digital search tools have had a mostly positive effect on their students' research habits and skills．But 64 percent said the technologies do more to distract（使 - - - ---分心） students than to help them academically． And 87 percent agreed that these technologies are creating an easily distracted generation with short attention spans．
The Pew Internet Project did the survey with the National Writing Project．Judy Buchanan is the vice director of the National Writing Project and a co-author of the report．Ms．Buchanan says digital research tools are helping students learn more and faster．Teachers really favor these tools because they are ways to make some of the learning exciting and engaging．Young people favor these tools．The goal is to really help them bee creators of meaningful content, and not just sort of consumers．
But one problem the survey found is that many students lack digital literacy．They trust too muck of the information they find on the Internet．Judy says these students haven't developed the skills to determine the quality of online information．It's something that really has to be taught and paid attention to．Because in a world in which things happen quickly, you do need to step back, reflect and analyze the information you have．
Another problem is blamed on something that might not seem like a problem at all: being able to quickly find information online．Teachers say the result is a reduction in the desire and ability of their students to work hard to find answers．They say students are overly dependent on search engines and do not make enough use of printed books or research libraries．
Many teachers are also concerned that the Internet makes it easy for students to copy work done by others instead of using their own abilities．

(答案→)D
解析：
试题分析: 本文是一篇调查结果，介绍了电子产品给教学带来了好处的同时也带来了一些问题。比如，因为缺少识别虚假和真实信息的能力，学生们很容易受到不好的影响；同时，调查还发现学生们也会因为在网上容易查到答案而不愿意努力学习。
【小题1】D主旨大意题。文章开头介绍了调查的结果Teachers say the digital age has had a good influence - and a not-so-good influence - on this generation of American teenagers．然后在下文再进行详细的叙述，故答案选D。
【小题2】A细节理解题。文章开门见山提出主题，然后在第二段讲述电子产品所带来的好处，而其余三段都是介绍电子产品可能造成的问题，故A选项正确。
【小题3】D细节理解题。根据后面的解释部分“学生应该被教给如何去培养技能去识别网上信息的质量”可知学生对于信息没有很好的判断能力，答案选D
【小题4】A细节理解题。从文章倒数第二段可知教师担心学生们不努力学习的原因是他们可能会从网上抄袭作业，答案选A。
