1、.阅读理解As data and identity theft becomes more and more common, the market is growing for biometric (生物测量) technologieslike fingerprint scansto keep others out of private espaces. At present, these technologies are still expensive, though.Researchers from Georgia Tech say that they have come up with a
2、 lowcost device (装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence (节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a users typing and
3、the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine peoples identities, and by extension, whether they should be given access to the computer its connected toregardless of whether someone gets the password right.It also doesnt require a new type o
4、f technology that people arent already familiar with. Everybody uses a keyboard and everybody types differently.In a study describing the technology, the researchers had 100 volunteers type the word “touch”four times using the smart keyboard. Data collected from the device could be used to recognize
5、 different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plasticlike parts. The team hopes to make it to market in the near future.本文是一篇说明文。数据和身份盗窃变得越来越普遍，目前，
6、像指纹扫描等技术仍然是昂贵的。本文介绍了一种新的科技智能键盘，它能给espace用户带来安全，而且这项技术也不贵。1Why do the researchers develop the smart keyboard?ATo reduce pressure on keys.BTo improve accuracy in typing.CTo replace the password system.DTo cut the cost of espace protection.解析：细节理解题。根据第一段的At present, these technologies are still expensi

16、he reason you want to form this new habit.本文是一篇说明文。主要介绍了养成良好的习惯的方法。1D解析：根据上文The most successful people all have certain habits in their daily routines.(最成功的人在日常生活中都有一定的习惯。)中“certain habits”和“The most successful people”可对应到选项D中的“These habits”和“their success”，故D项“这些习惯有助于促成他们的成功”符合语境。故选D。2E解析：根据本段的主题句“
17、Set your goal(设定目标)”，与上文Before you can begin to work on your new habit, it is worthwhile to consider your goal.(在你开始培养新习惯之前，有必要考虑一下你的目标。)中的“consider your goal”可知，此处讲的应是要弄清楚自己的目标是什么，故E项“弄清楚你究竟希望实现什么”符合语境。故选E。3B解析：通读第三段可知，主要讲与目标一致的好习惯能提高你实现自己的目标的可能性。再结合该段中的“After you have set your goal and worked out
18、all of the specifics (细节) of achieving that goal, find a habit that is part of achieving that goal.(在你设定了目标，并制定了实现目标的所有细节之后，养成一个习惯，这也是实现目标的一部分。)”可知，B项“找到你想养成的习惯”最能概括本段的主题。故选B。4G解析：根据该段的主题句以及空前的“take some time to consider your motivation(花点时间考虑你的动机)”以及空后的“Good motivation can be the difference between
19、 success and failure in terms of forming a new habit.(在形成新习惯方面，良好的动机可能是成功和失败的区别。)”可知，本段的中心内容涉及“动机”，故G项“Your motivation is the reason you want to form this new habit(你的动机是你想要养成这个新习惯的原因)”符合语境。故选G。5F解析：根据本段的主题句“Give yourself time(给自己一点时间)”以及上文As you work to form your new habit, just keep in mind that it may be a while before it comes true.(当你努力养成新习惯时，请记住，这可能需要一段时间才能实现。)可知，良好的习惯不是一朝一夕就能养成的，它需要时间，因此在养成良好习惯的过程中要对自己有耐心，故选F项。
