“If you get enough data,a model can be built pretty easily,” Oli Buckley,a professor of Internet security.“If it works on one keyboard,it will likely work on the next. The MacBook has a nice,quiet keyboard,so the idea is that if it works on something quiet,it will have a wide-reaching ability on louder keyboards”. While this all sounds pretty scary,not to mention a new form of hacking（侵入） to look out for,it isn’t quite as worrying as it sounds. “A good sample of data is needed for it to work,so this changes if you’re using a Dell,a MacBook or an external keyboard. Also,factors change. Some people type louder and harder,or my keyboards full of cat hair so that impacts things slightly,”says Buckley.
04 Unit 4 Living with technolog江1月卷) When was the last time you used a telephone box?I mean to make an actual phone call—not to shelter from the rain. Ages ago,right?The last time I used a phone box for its intended purpose was...2006.I was conducting auditions（试演） for my play in my tiny old shared house in London. Hoping to impress some talented actors to come and work for me for nothing,I spread some throws over the sofas and lit candles to make it seem a bit more “young professional”.
For a few months after the “library” opened,I didn’t bother taking a look,as I had assumed that it would be stuffed full of cheesy love stories. Then I noticed folk conducting spring cleans dropping boxes of voluminous books on various subjects there. And these books were free. This unbeatable price-point encouraged me to experiment with dozens of titles that I would never normally consider buying. And I’ve discovered some great books! If I ever get trapped outside my house again,my local telephone box will,sadly,no longer be able to connect me with my keys. But it can certainly keep me entertained while I wait for my wife to rescue me.
B
A. The play. B. The shared house.C. The sofa. D. The telephone box.
[解析] 词义猜测题。根据第一段最后两句可知，作者为了组织剧本试演，特意布置了房间，以使房子看起来更像一个“年轻专业人士”的生活空间，所以it指代的是作者的合租房。
[解析] 推理判断题。根据第二段可知，作者被锁在了门外，手机在房间里，需要联系房东的房产管理代理人来获取备用钥匙，所以作者2006年使用电话亭是为了拨打紧急电话。
3. What do we know about the “mini community library”?( )
B
A. It provides phone service for free.B. Anyone can contribute to its collection.C. It is popular among young readers.D. Books must be returned within a month.
B (2024·山东潍坊统考) All the hard work that you’ve spent making strong passwords,combining pet names with numbers,symbols and birthdates could all soon be for nothing as a new artificial intelligence（AI） model achieves a 95% accuracy of understanding keystrokes（按键）. At least that’s the extreme view of a team of British researchers. Using a deep learning model,they were able to steal data from a laptop’s keyboard using a microphone to understand what is being typed. This,in theory,would allow hackers who were able to gain access to your laptop to obtain what is being typed including messages and passwords.
[解析] 细节理解题。根据第四段中的“And these books were free.”和最后一句“And I’ve discovered some great books!”可知，作者发现“迷你社区图书馆”里有很多优秀的免费书籍，所以开始使用。选项C中的excellent和文章中的great是同义替换。
[解析] 细节理解题。根据第三段最后一句“...any passer-by can‘borrow’ a book from its shelves,and return it later,or replace it with another title from their own collection.”可知，任何人都可以为“迷你社区图书馆”捐赠书籍。
2. Why did the author use the telephone box in 2006?( )
A
A. To place an urgent call. B. To put up a notice.C. To shelter from the rain. D. To hold an audition.
4. Why did the author start to use the “library”?( )
C
A. He wanted to borrow some love stories.B. He was encouraged by a close neighbour.C. He found there were excellent free books.D. He thought it was an ideal place for reading.
As I rushed outdoors to empty the wastepaper baskets,the door swung shut behind me. Suddenly I was locked outside. My mobile phone was inside,but luckily there was a telephone box across the street. So,I called Directory Assistance,got put through to our landlady’s managing agent,and had a spare key sent to me with just enough time to get back in before the actors arrived. As it has been many years since I last used one,I should hardly be surprised that there are no longer any public telephones near my house. The last one standing has just been turned into a “mini community library”:any passer-by can “borrow” a book from its shelves,and return it later,or replace it with another title from their own collection.
【语篇导读】本文主要说明了随着手机的普及，电话亭逐渐被淘汰。作者回顾了自己最后一次使用电话亭的经历，并发现家附近最后一个电话亭被改造成了“迷你图书馆”，这一功能的转变为社区提供了新的价值。
1. What does the underlined word “it” in the first paragraph refer to?( )
The first step for this attack to work is by recording the keystrokes on someone’s keyboard. This is needed to train the algorithm（计算程序）.While this could be done from the laptop’s microphone,it could equally be achieved by placing a smartphone near the computer. By pressing 36 keys on a modern MacBook Pro 25 times each and recording the sounds produced,the researchers gained a full set of training data. This information is turned into waveforms to show identifiable differences between each key. With this information in hand,they could then build a machine-learning model to understand which of these waveforms lines up with which key.
