科技发展与信息技术创新，科学精神，信息安全

1.D细节理解题。根据第一段中的“At present, these technologies are still expensive, though.”和第二段中的“Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard.”可知，研究人员开发智能键盘是为了降低保护电子空间的成本。故选D项。

2．C细节理解题。根据第二段中的“These patterns are unique to each person. Thus, the keyboard can determine people's identities…”可知，因为每个人的打字方式不同，这使得发明智能键盘成为可能。故选C项。

3．B细节理解题。根据最后一段中的“…the keyboard should be pretty straightforward to commercialise and is mostly made of inexpensive, plastic­like parts.The team hopes to make it to market in the near future.”可知，研究者认为实现智能键盘商业化应该会很容易，其造价并不昂贵，因此研发团队希望在不久的将来智能键盘能早日面世。故选B项。

4．D推理判断题。本文是一篇说明文，介绍了一种防止个人身份和数据在电子空间被盗的高科技智能键盘，由此可推断本文最有可能刊登在(科学) 杂志上。故选D项。diary“日记”；guidebook“指导手册”；novel“小说”，均不符合题意。
