(2019·全国卷Ⅰ)As data and identity theft becomes more and more common, the market is growing for biometric (生物测量) technologies—like fingerprint scans—to 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 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 user's typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by extension, whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right.
It also doesn't require a new type of technology that people aren't 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 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.
篇章导读：本文是一篇科研报道。来自佐治亚理工学院的研究人员发明了一种智能键盘，可以通过分析用户的打字模式来判断该用户是不是安全访客。
5．Why do the researchers develop the smart keyboard? A．To reduce pressure on keys. B．To improve accuracy in typing. C．To replace the password system. D．To cut the cost of espace protection.
答案：D 推理判断题。根据第一段最后一句以及第二段第一句可推知，研究者研发这种智能键盘是为了降低网络安全保护技术的成本。故选D。
6．What makes the invention of the smart keyboard possible? A．Computers are much easier to operate. B．Fingerprint scanning techniques develop fast. C．Typing patterns vary from person to person. D．Data security measures are guaranteed.

答案：C 推理判断题。题干为“是什么让智能键盘的发明成为可能”，也就是问这一发明的核心依据是什么。根据第二段中的“These patterns are unique to each person.Thus, the keyboard can determine people's identities ...”可知，正是因为每个人的打字模式不同，这种智能键盘就可以通过分析用户的打字力度及节奏等来判断该用户是不是安全访客。故选C。
7．What do the researchers expect of the smart keyboard? A．It'll be environmentfriendly. B．It'll reach consumers soon. C．It'll be made of plastics. D．It'll help speed up typing.
答案：B 细节理解题。根据题干“研究者对于智能键盘有什么期望”可直接定位到最后一段的最后一句话“该团队希望在不久的将来将智能键盘推向市场”。故选B。
8．Where is this text most likely from? A．A diary. C．A novel.
B．A guidebook. D．A magazine.
答案：D 推理判断题。根据本文的话题“智能键盘”以及第二段第一句中的“Researchers from Georgia Tech say that they have come up with a lowcost device ...”，尤其是其中的关键词“Researchers” “lowcost device”等来推断，这篇文章是一篇科研报道，最有可能出现在杂志上。故选D。
Ⅲ.短文改错
(2019·山东省枣庄八中月考)I have never been to a cooking school. I learned cooking from my mother because she was really interesting in teaching me how to cook. The main reason for this was because my mother didn't know how to cook something when she got married.
My grandmother never allowed her stay in the kitchen. At the age of 25, my mother started cooking, it was very hard for her. However, she had to take a few cooking class to prepare our meals. After having that experience, she decided to teach me how to cook.
I remember I always helped out my mother when I was with her in the kitchen enjoy cooking. Nowadays, I am thankful to that experience.

⑩for
1．interesting→interested 考查固定搭配。句意：我从未上过烹饪学校。我从妈妈那里学到了烹饪，因为她对教我做饭很感兴趣。be interested in ... 为固定搭配，意为“对……感兴趣”，所以把interesting改为interested。
2．because→that 考查名词性从句的连接词。分析句子结构可知，这是一个表语从句，陈述一个事实，而非原因，故把because改为that。
3．something→anything 考查不定代词。根据上下文的内容可知，是说“我”妈妈在结婚时什么饭菜也不会做，在否定句中，应用anything。
4．stay前加to 考查固定搭配。allow sb. to do sth.为固定搭配，“允许某人做某事”。因此要在stay前加to。
5．it前加and或it→which 考查连词或定语从句的引导词。句意：在25岁的时候，妈妈开始做饭，这对她来说很难。分析句子“At the age of 25, my mother started cooking, it was very hard for her.”可知，这是两个句子，两个句子必须有一个连接词。根据句意可知，要么用并列连词and把两个句子连接起来，要么用关系词引导定语从句。改成定语从句“At the age of 25, my mother started cooking, which was very hard for her.”，其中用which指代前面的整个主句。所以也可把it改为which。
6．However→Therefore 考查副词。根据上下文可知，这里表示结果，不是转折。 7．class→classes 考查名词。class “课程”被a few(一些)修饰，应用名词的复数形式，class在本句中是可数名词，因此class要用复数形式，故把class改为classes。
8．去掉out 考查动词搭配。help out意为“帮助解决难题，帮助摆脱困境”；help sb.意为“帮助某人”。此处语境并无前者的深刻含义，故去掉out。
9．enjoy→enjoying 考查非谓语动词。分析句子结构可知，enjoy在句中应作伴随状语，其逻辑主语为“I”，故把enjoy改为enjoying。
