Passage1阅读理解
Researchers at the University of Alabama in Birmingham suggest that brainwave-sensing headsets (耳麦), also known as EEG headsets, need to do more to protect users after a study which shows hackers (黑客) could guess a user’s bank account passwords by monitoring his brainwaves.
Nitesh Saxena, Ph.D., professor in the UAB College of Computer and Information Sciences Department, and his team found that a person who stopped a video game and entered into a bank account while wearing an EEG headset was at a risk for having his passwords stolen by a bad software program. Saxena and his team used one EEG headset that could be bought by customers online to show how easily an ill software program could eavesdrop on a user’s brainwaves. While typing, a user’s inputs meet with their visual processing, as well as hand, eye and head muscle movements. All these movements are caught by EEG headsets.
The team asked 12 people to type passwords into a text box as if they were entering into an online account while wearing an EEG headset, in order for the software to train itself on the user’s typing and the present brainwave. The team found that, after a user entered passwords within the ill software program that could make educated guesses about the passwords, the user entered by reading the EEG data recorded. It increased the chance of guessing a six-letter password from one in 500,000 to one in 5.
“Given the growing popularity of EEG headsets and the different ways in which they could be used, they will become part of our daily lives,” Saxena said. “It is important to study the possible risks together with this new technology to raise users’ attention to the risks and develop solutions to the bad attacks.” One possible solution suggested by Saxena and his team is the insertion (插入) of noises anytime a user types a password while wearing an EEG headset.
1．How do hackers guess passwords of a user’s bank account
A．They use a software program.
B．They use a new-type computer.
C．They guess the user’s brainwaves.
D．They talk with the user on the net.
2．The underlined words “eavesdrop on” in Paragraph 2 refer to “________”.
A．make full use of B．watch carefully
C．record or write down D．gain or get secretly
3．What was the result of the research of Saxena and his team in Paragraph 3
A．They made a very exact answer.
B．They got close to the passwords.
C．They got a part of the passwords.
D．They failed to get the passwords.
4．Why do EEG headsets need to do more to develop solutions
A．More and more hackers come about.
B．More people use online bank accounts.
C．EEG headsets will become more popular.
D．EEG headsets still have problems in quality
Passage2阅读理解
“Instagram (a social networking app) will cut out many users’ accounts on December 20. To protect your account, repost this warning #KeepMyAccountSafe.” Every few months, it happens again — dozens of annoying posts from my kids’ friends suddenly start to appear on my Instagram news feed.
According to a new study by Stanford University, most kids don’t know what news is false. Researchers asked more than 7,800 middle school and high school students to complete 56 tasks, like distinguishing an advertisement from a real news story on a website and determining which blog in a series was most reliable. They found that students judged the credibility of blogs based not on the source of the material, but on how much detail they contained, or whether a large photo was attached.
“Many people assume that because young people are fluent in social media, they can distinguish fake news, but our work shows the opposite to be true,” wrote the lead study author Sam Wineburg, a professor at Stanford’s Graduate School of Education.
Both Google and Facebook are now taking steps to prevent misleading news from making its way on their platforms, but they won’t be able to eliminate it completely. That is why it’s now more important than ever to teach our kids to think critically when it comes to believing various information sources.
“In the coming months, we look forward to sharing our assessments and working with educators to create materials that will guide young people in the sea of disinformation they encounter online,” said Wineburg.
5．How does the author introduce the topic of the passage
A．By stating opinions. B．By citing sayings.
C．By quoting a post. D．By showing findings.
6．According to researchers, what determines the credibility of online information
A．The size of relevant photos B．The popularity of the website.
C．The amount of detail. D．The source of the material.
7．What does the underlined word “eliminate” mean in Paragraph 4
A．Update. B．Remove. C．Estimate. D．Digest.
8．Which of the following can be the best title for the passage
A．Stronger Together: The Internet Changes Our Life
B．Reliable News Has No Place on Social Media
C．Be Careful: Kids Are Bad at Identifying Fake News
D．Educators Have a Long Way to Go to Guide the Young.

Passage3
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写词数应为150左右。
Losing a parent is one of the most painful parts of life. No matter how old we are when they leave us, it can be a heartbroken experience. Our memories are all that is left of them and happy reminders of their love turn into our most valuable treasures. That's how Mara Soriano feels about the teddy bear that she tragically lost in her recent move to a new apartment.
Diagnosed with cancer, Mara Soriano's mother, Marilyn, gave her daughter the bear as a gift in 2017. After her mother's death last June, the gift became even more special. "That bear was basically the last reminder of my mom. It was her voice that accompanied me," she said in an interview.
The plush (长毛制的) toy didn't cost a lot, but it contained a recording of her mother's voice telling her that she loved her and was proud of her. The bear, called Mama Bear, was in the backpack that contained electronics like an iPad and a Nintendo Switch. When the bag was stolen last week during the move, the 28 -year-old was heartbroken-- not for the gadgets(小装置), but for Mama Bear.
Mara posted a photo of her and her Mama Bear on Instagram, explaining the importance of the bear. Millions of users were touched by the story. More and more people were talking about the bear, but there was no good news for Mara. So again and again she posted online about the item and the story behind it, hoping it could catch more viewers' attention in a big way.
Actor Ryan Reynolds was moved by Mara's story and then posted an appeal(请求)for Mama Bear's safe return. "I think we all need this bear to come home," he wrote. Along with the message, he also offered a reward for the people who found the bear.

参考答案
Part2相关话题阅读练
1．A 2．D 3．B 4．C
【导语】这是一篇说明文。讲述了EEG耳机的安全性问题，研究人员发现用户在佩戴EEG耳机过程中，有着被黑客通过监测脑电波来窃取密码的风险，随着该耳机愈发普遍，建议需要付诸更多的努力来保护用户的安全信息。
1．细节理解题。根据第二段首句“Nitesh Saxena, Ph.D., professor in the UAB College of Computer and Information Sciences Department, and his team found that a person who stopped a video game and entered into a bank account while wearing an EEG headset was at a risk for having his passwords stolen by a bad software program. (阿联酋大学计算机与信息科学系教授Nitesh Saxena博士和他的团队发现，当一个人在戴着EEG耳机暂停一个视频游戏并进入了一个银行账户时，他的密码有被不良软件程序窃取的风险)”可知，黑客是通过使用某个不良软件来窃取用户密码，所以选项A符合题意。故选A。
2．词句猜测题。根据第一段“Researchers at the University of Alabama in Birmingham suggest that brainwave-sensing headsets (耳麦), also known as EEG headsets, need to do more to protect users after a study which shows hackers (黑客) could guess a user’s bank account passwords by monitoring his brainwaves. (伯明翰阿拉巴马大学的研究人员建议，脑电波传感耳机, 也被称为EEG耳机，需要做更多的工作来保护用户，因为一项研究显示黑客可通过监测用户的脑电波来猜出用户的银行账户密码)”和第二段首句“Nitesh Saxena, Ph.D., professor in the UAB College of Computer and Information Sciences Department, and his team found that a person who stopped a video game and entered into a bank account while wearing an EEG headset was at a risk for having his passwords stolen by a bad software program. (阿联酋大学计算机与信息科学系教授Nitesh Saxena博士和他的团队发现，当一个人在戴着EEG耳机暂停一个视频游戏并进入了一个银行账户时，他的密码有被不良软件程序窃取的风险)”可知，佩戴EEG耳机的用户很容易被不良软件监测脑电波，进而窃取他们的账户密码，由此可推断出此处“eavesdrop on”表示窃听，偷听的含义，呼应关键词“stolen”，所以D选项符合题意。故选D。
3．细节理解题。由第三段“The team found that, after a user entered passwords within the ill software program that could make educated guesses about the passwords, the user entered by reading the EEG data recorded. It increased the chance of guessing a six-letter password from one in 500,000 to one in 5. (研究团队发现一名用户在不良软件程序中输入密码后（该不良软件可对密码进行有根据的猜测），用户通过读取记录的脑电图数据进入。它将猜出6位字母密码的几率从50万分之一提高到五分之一)”可知，他们最终得到的密码是接近于正确密码的。所以B选项“They got close to the passwords. (他们接近了正确密码)”符合题意。故选B。
4．细节理解题。根据最后一段“Given the growing popularity of EEG headsets and the different ways in which they could be used, they will become part of our daily lives (鉴于EEG耳机的日益普及和它们的不同使用方式，它们将成为我们日常生活的一部分)”可知，因为EEG耳机在日常生活中越来越普遍，所以需要展开更多工作来研究解决方案。故选C。
5．B 6．D 7．B 8．C
【导语】这是一篇说明文。文章主要说明了斯坦福大学的一项新研究发现，大多数孩子不知道什么新闻是假的。文章介绍了这项研究开展的过程以及发现，研究人员指出应当教我们的孩子在相信各种信息来源时进行批判性思考。
5．推理判断题。根据第一段“‘Instagram (a social networking app) will cut out many users’ accounts on December 20. To protect your account, repost this warning #KeepMyAccountSafe.’ Every few months, it happens again — dozens of annoying posts from my kids’ friends suddenly start to appear on my Instagram news feed. (“社交网络应用Instagram将于12月20日关闭许多用户的账户。为了保护您的账户，请转发此警告#KeepMyAccountSafe。” 每隔几个月，这种事情就会再次发生——来自孩子的朋友们的几十条烦人帖子会出现在我的Instagram动态中)”可推知，在第一段中作者通过引用自己Instagram动态中出现的一些说法来引入文章的主题。故选B。
6．推理判断题。根据第二段中“According to a new study by Stanford University, most kids don’t know what news is false.(根据斯坦福大学的一项新研究，大多数孩子不知道什么新闻是假的)”和“They found that students judged the credibility of blogs based not on the source of the material, but on how much detail they contained, or whether a large photo was attached.(他们发现，学生们判断博客的可信度不是基于材料的来源，而是基于它们包含多少细节，或者是否附有一张大照片)”可知，研究人员认为，大多数孩子不知道什么新闻是假的，是因为他们判断博客的可信度不是基于材料的来源，由此推知，决定网络信息可信度的是材料的来源。故选D。
7．词句猜测题。根据画线词所在句“Both Google and Facebook are now taking steps to control misleading news from making its way on their platforms, but they won’t be able to eliminate it completely. (谷歌和Facebook现在都在采取措施控制误导新闻在他们的平台上传播，但他们不可能完全eliminate它) ”中but可知，上下文有转折，虽然谷歌和Facebook在采取措施控制误导新闻的传播，但不可能完全消除这些新闻。画线词eliminate意思为“消除”，与remove意思相近。故选B。
8．主旨大意题。通读全文，结合第二段中“According to a new study by Stanford University, most kids don’t know what news is fake.(根据斯坦福大学的一项新研究，大多数孩子不知道什么新闻是假的)”可知，文章介绍了斯坦福大学的研究发现，大多数孩子不知道什么新闻是假的，并分析了原因，给出了建议。由此推知，B选项“小心：孩子们不擅长识别假新闻”是文章最佳标题。故选C。
9．G 10．D 11．E 12．F 13．B
【导语】本文是一篇说明文，主要讲了三个安全上网，避免受到坏的影响的方法。
9．空前说“Today I thought I’d blog about a question that has been asked many times—how do you stay safe online and avoid bad experiences on the Internet I am not an expert.(今天，我想我要写一个被问了很多次的问题——如何保证网络安全，避免在网络上的糟糕经历？我不是专家。)”，空后提出了三种方法，说明作者虽然不是专家，但是还是知道一些方法，G选项“But many years as a blogger have taught me a thing or two.(但是多年的博客生涯教会了我一些东西。)”说明了作者知道一些方法的途径，引起下文的几种方法，因此G选项承上启下，符合语境，故选G。
10．空前说“If you see or read something that makes you feel uncomfortable, leave the site immediately.(如果你看到或读到让你感觉不舒服的东西，立即离开该网站。)”，也就是立刻离开，不做任何评论，D选项“Don’t post comments or click on anything.(不要发表评论或点击任何东西。)”所讲的方法和空前说的“立刻离开网站”表达意思差不多，因此D选项承接上文，符合语境，故选D。
11．空前说“Second, protect your privacy.(第二，保护你的隐私。)”，空后说“Someone might use the information to steal your identity.(有人可能会利用这些信息窃取你的身份。)”，E选项“Don’t give out your address or phone number.(不要留下你的地址或电话号码。)”中的“address or phone number(地址或电话号码)”和空后的“the information(信息)”相一致，说明了保护隐私的具体方法，因此E选项承上启下，符合语境，故选E。
12．空后说“Like a troll, a cyberbully will also write something mean but it is usually directed at particular people.(像喷子一样，网络恶霸也会写一些刻薄的东西，但通常是针对特定的人。)”，空格处应说网络恶霸除了这一点以外还会做的事情，F选项“A cyberbully uses the Internet to be mean to others.(网络恶霸利用互联网对他人刻薄。)”说明的是网络恶霸会做的事情，因此承上启下，符合语境，故选F。
13．空前说“Have you had any bad experiences online, or do you have some good advice for staying safe (你在网上有过不好的经历吗 或者你有一些关于安全的好建议吗？)”，空格处应该说如果有的话该怎么做，B选项“Post your comments below!(在下面发表你的评论！)”说明了如果你在网上有过不好的经历或有一些关于安全的好建议可以在下面发表评论，因此承接上文，符合语境，故选B。
14．C 15．D 16．B 17．A 18．C 19．D 20．B 21．C 22．A 23．B 24．A 25．D 26．B 27．C 28．A 29．D 30．A 31．D 32．B 33．C

【导语】这是一篇说明文。文章主要介绍了黑客及其工作内容。
1．考查非谓语动词。句意：他们花了好几天的时间寻找方法，侵入任何可以连接到互联网的东西，以获取从未被看到的信息。分析句子结构可知，句中已有谓语动词，空处为非谓语动词作目的状语，所以用动词不定式。故填to access。
2．考查冠词。句意：杰克为自己的谋生之道感到自豪。固定搭配for a living“为了谋生”。故填a。
3．考查非谓语动词。句意：在好莱坞，黑客通常被描述为在暗室中从事非法活动的戴头巾的人，同时敲打着键盘。分析句子结构可知，句中已有谓语动词，空处为非谓语动词作后置定语，修饰figures，该动词和修饰的名词之间存在被动关系，所以用过去分词作定语。故填involved。
4．考查副词。句意：实际上，黑客是电脑编程和解决问题的专家。此处修饰后面整个句子，用副词actually。故填Actually。
5．考查主谓一致。句意：黑客是一种活动，任何活动与犯罪的区别在于许可。根据全文的时态可知，此处应为一般现在时，主语为what引导的主语从句，what指代permission，谓语动词用单数。故填is。
6．考查连词。句意：司机可以自由驾驶，但他们没有每小时驾驶150英里的许可——这是违法的。根据句意可知，司机可以自由驾驶，但他们没有每小时驾驶150英里的许可，所以前后两句之间为转折关系，用转折连词but或者yet。故填but或yet。
7．考查介词。句意：银行家可以转移客户的资金，但如果他们未经许可就这样做，那是违法的。根据前文“they do not have permission”及与前一句的并列关系可知，这里指的是银行家可以转客户的钱，但是如果他们在没有允许的情况下这么做，那就是非法的，所以用介词without“没有”,和后面的名词构成介词短语，在句中作状语。故填without。
8．考查动词语态。句意：参与非法使用黑客的人不应被称为“坏黑客”，而应被称为“威胁行为人”。主语someone与call之间是被动关系，应用被动语态，情态动词should后加be动词原形。故填be called。
9．考查名词复数。句意：黑客就是像杰克和他的IBM团队一样的人——安全专家。此处表示“安全专家”，所以用名词professional，为可数名词，前面没有限定词，应用复数形式，表泛指。故填professionals。
10．考查形容词。句意：黑客在确保公司和人员安全方面发挥着至关重要的作用。固定搭配keep sb./sth. safe“保持某人/物安全”，形容词作宾语补足语。故填safe。

¤读后续写练
Luckily, the Internet did its thing. It’s a bit of a modern-day wonder that would never have happened without social media. Mara’s story was quickly and continuously spread via the Internet. Several days later, with anxiety and worry, Mara finally got positive feedback. Mara said she got an email from someone. The sender told her the bear was on the way back. On Tuesday night, Mara’s bear came home.
The email was from the woman who sent the bear back. She told Mara that she was deeply touched by Mara’s story. She didn’t want the reward, just hoping that Mara could live a happy life in the future. Mara is getting married next summer and the bear is going to have a special seat at the ceremony--the one her mother would sit in. For now, she’s keeping Mama Bear close and sending thanks to those who helped with the happy reunion.
