Kyle, a student who I never saw text in class, gave the teacher his phone. When the teacher left, two students who I often saw text in class started boasting (自夸) about how they sent text messages and never got caught. “Kyle, you don't text in class that way！” one of them said. “I put my phone under my desk so it looks like I'm looking at my textbooks.” 课后课时作业（一） 81 “Isn't it funny that we always text and never get caught, but the first time Kyle does it, he gets caught？” the other one laughed. They must have thought they were smart, because they never got caught and Kyle did. But which situation is worse: getting caught, or getting away with it? Rules are there for a reason. These two students might not have got caught, but neither of them had good grades. They keep texting in class, not paying any attention.

They take it one step at a time, starting with smaller rules. Kyle might have got caught, but at least he learned a good lesson. He will not break the rules in the future, so he will learn more in class and stay out of trouble.

How can you avoid __6__ (fool) by a deepfake? Wael Abd­Almageed suggests not __7__ (immediate) believing what you see online.

Despite my determination, it's hard not to feel sorry for him. As the end of Year 6 draws closer, the weeks are filled with stories of new classmates whose parents have, as one friend texted recently, “cracked”. Apps are springing up so that friends going to different secondary schools can easily keep in touch. But it pains me to see the anxiety and effect that smartphones cause. So I stick to my decision. 精深阅读 课后课时作业（一） 95 There is research conducted by the Office of Communications (Ofcom) showing that school bullying is more likely to happen on a device rather than face to face. School bullies aren't new, but their ability to reach the sanctuary (庇护) of the home is a recent development. Headteacher Jon Boyes of Herne Bay High School told parents that they'd have to sort out arguments between pupils that had occurred online. According to the research, children who were given a phone later went on to experience better mental well－being in relation to their self－confidence and their ability to relate to others. However, those who received a phone at a younger age were more likely to experience sad thoughts, feelings of aggression towards others and the sense that they were separated from reality. 课后课时作业（一） 96 Parents should be willing to consider the idea that it's possible to refuse to follow the herd at least until their children are old enough to judge what they find on the Internet. There is power in questioning the idea that a smartphone is the only way to keep a child safe and ensure they have access to important friendships. My son is only 10. He's nowhere near ready to deal with the confusing and harmful garbage that he will no doubt find on the Internet. He hasn't developed the emotional maturity to skillfully avoid the litter along his route. As his parent, why would I believe he could deal with what many adults struggle to get a handle on? Instead, I believe that he can survive with his old－fashioned phone. It turned out that he agreed. 课后课时作业（一） 97 篇章导读：本文是一篇夹叙夹议文。文章主要阐述了手机给孩子带来的负面影响以及父母应该如何应对孩子对手机的渴望。 课后课时作业（一） 98 1．What factor strengthens the author's decision? A．The text messages from a friend.

There are more and more apps providing help for students. PhotoMath The new, seemingly magic app allows users to take pictures of a math problem, and then receive a step­by­step solution. It is now the number one free app on the App Store. A PhotoMath spokeswoman says educators have welcomed the app with positive reviews, but the software causes a lot of angry public discussion and disagreement. Why? This is because students can use it to cheat when doing their math homework. 课后课时作业（二） 112 iHomework Whether you're a high school student or a college student, there's one thing you've got for sure: a lot of homework. iHomework can help you keep track of all your homework. It can help you arrange it in a particular order according to types, or based on deadlines. Homework Helper Chinese Internet search company Baidu has launched an app called Homework Helper with which students can get answers to homework. Users post a picture or type their homework questions onto an online forum (论坛), and those who answer the questions can win e­coins that can be used to buy devices like laptops. The app has logged 5 million downloads, much to the concern of many parents who argue that the students spend less time thinking about challenging problems. 课后课时作业（二） 113 篇章导读：本文是一篇应用文。文章介绍了四款为学生提供帮助的教育应用程序。 WolframAlpha WolframAlpha is similar to PhotoMath, but it focuses on older students studying high levels of math and doesn't support photos. The service also produces step­by­step solutions to advanced topics, making it a popular tool for college students. 课后课时作业（二） 114 1．What is the public's worry about the app PhotoMath? A．It can't recognize pictures. B．It doesn't provide a step­by­step solution. C．It makes cheating at homework more likely to happen. D．It encourages students to use smart phones more frequently. 解析：细节理解题。根据PhotoMath部分中的“This is because students can use it to cheat when doing their math homework.(这是因为学生在做数学作业时可以用它来作弊。)”可知，公众对PhotoMath应用程序的担忧在于它使得在家庭作业中作弊的情况更容易发生。故选C。 课后课时作业（二） 115 2．What can we learn about Homework Helper? A．It is thought highly of by teachers. B．It is unpopular among Chinese students. C．Many parents think it harmful to children's study. D．Answering questions on the app wastes students' time. 解析：推理判断题。根据Homework Helper部分中的“The app has ... about challenging problems.(这款应用程序的下载量已达到500万次，许多家长对此表示担忧，他们认为学生们花在思考具有挑战性的问题上的时间更少了。)”可推知，许多家长认为Homework Helper对孩子们的学习有害。故选C。 课后课时作业（二） 116 3．Which app is the best choice if you want to deal with advanced math problems? A．PhotoMath. B．iHomework. C．Homework Helper. D．WolframAlpha. 解析：细节理解题。根据WolframAlpha部分中的“WolframAlpha is similar to ... doesn't support photos.(WolframAlpha类似于PhotoMath，但它专注于学习高水平数学的高年级学生，并且不支持照片。)”可知，如果你想解决高等数学问题，WolframAlpha应用程序是最好的选择。故选D。 课后课时作业（二） 117 B Recent research demonstrates the harmful mental health effects caused by social media use, including increased rates of depression, anxiety, suicidal tendency and self­harm. Adolescents (青少年) who spend more than three hours per day on social media face twice the risk of poor mental health outcomes. Addictive feeds—designed to make use of personal data to intensify (增强) users' content that will keep them on the platform for as long as possible—have dramatically heightened the risk to young users' well­being and made our children addicted to these social media outlets. 课后课时作业（二） 118 In the first seven years after addictive feeds were introduced, suicide rates for 10­ to 14­year­old girls doubled and hospitalizations for suicidal tendencies and attempts increased nearly twice for all adolescents. Instead of responding to the problem, social media empires have made great efforts to keep and capture user engagement, and the consequences have been catastrophic． Beyond the direct harm of social media addiction, the collection of children's data by these giant companies puts our kids at huge risk, leaving them vulnerable (易受伤的) to having their location and other personal data tracked, shared and sold online. As a consequence, that data is at greater risk of falling into the wrong hands—including human traffickers, identity thieves and others who might prey (欺凌) on young people. 课后课时作业（二） 119 篇章导读：本文是一篇说明文。文章主要介绍了网络社交媒体通过让人上瘾的内容危害青少年健康的现象，并呼吁大家保护青少年免受社交媒体的伤害。 We will not stand by and watch an arms race among social media mega­corporations (大型企业) over who can best profit from our children's pain and addiction. That is why we should use and are using every tool at our disposal to fight back against these damaging practices: from the courthouse to the statehouse. 课后课时作业（二） 120 4．What can we learn about addictive feeds? A．They are food that can easily satisfy people. B．They are Internet content that can get people addicted. C．They are kept on the platform just for a short period of time. D．They are personal data stored on the Internet for convenience. 解析：细节理解题。根据第二段“Addictive feeds ... social media outlets.”可知，上瘾式推送是指能让人上瘾的网络内容。故选B。 课后课时作业（二） 121 5．Which word can best replace the underlined word in Paragraph 4? A．destructive B．striking C．unique D．effective 解析：词义猜测题。第三段介绍了上瘾式推送对青少年的严重危害，画线词上文“Instead of responding to ... capture user engagement”表明社交媒体并未对这一问题做出回应，却努力保持、吸引客户，由此可推知，这个后果是灾难性的，画线词与destructive(破坏性的，毁灭性的)意思相近。故选A。 课后课时作业（二） 122 6．Why has the author written the article? A．To introduce a research finding. B．To explain the harms caused by addictive feeds. C．To blame irresponsible social media mega­corporations. D．To call on people to protect children against social media harms. 解析：推理判断题。根据最后一段中的“We will not stand by ... these damaging practices (我们不会眼睁睁地看着社交媒体大型企业之间进行军备竞赛，谁能最大限度地从我们的孩子的痛苦和成瘾中获利。这就是为什么我们应该并正在使用我们所掌握的一切工具来反击这些破坏性做法)”可推知，作者写作本文的目的是呼吁人们保护孩子们免受社交媒体的伤害。故选D。 课后课时作业（二） 123 7．Which of the following can be a suitable title for the text? A．Mental Health Is Safe for Children B．Teens Should Be Kept Away from Internet C．Addictive Feeds Heighten Great Risks to Teens D．Social Media Empires Are to Blame for Children's Safety 解析：标题判断题。通读全文可知，文章介绍了社交媒体通过让人上瘾的内容对青少年产生危害。C项(成瘾式信息推送会显著增加青少年面临的风险)最适合作为文章标题。故选C。 课后课时作业（二） 124 Ⅱ　读后续写 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。 “Surprise！” was the first thing I heard when I opened the door. My family and friends were all smiling at me. There were colorful balloons all over the house, a big poster saying “HAPPY BIRTHDAY”， and of course a cake with 12 candles. It was a wonderful feeling. I knew that I had finally turned twelve and I might possibly get the thing I wanted most. 课后课时作业（二） 125 I saw my mom and dad coming towards me with a small box which seemed to be a birthday present. When I opened the box, I couldn't believe my eyes. I had really gotten a mobile phone! Throwing myself into their arms, I let out a cry of joy, “Thank you! I love you guys！” “You're welcome. We knew this was going to make you happy but we didn't only get you this because you turned twelve, but also because you are doing well in school. We expect you to keep getting good grades.” “Of course I will.” I said confidently. As soon as I got to school the next morning, I was showing off my phone and asking everyone for their number. It was cool how I got so many contacts on the first day. 课后课时作业（二） 126 It felt like I didn't even exist in that class anymore. I wouldn't pay much attention to the teachers because I was too busy on my phone. However, I didn't get caught using it. I am pretty sure that the teacher did notice that I stopped paying attention to her because a week later we took a test and I failed. What was worse, my mom had to sign the test. It was hard to show my mom the test. She was used to seeing A's and B's on my tests. Finally, I showed it to her, and she couldn't believe it. She was angry but most of all, she was disappointed. 注意： 1．续写词数应为150个左右； 2．请按如下格式在相应位置作答。 课后课时作业（二） 127 Realizing the reason for my failure, my parents started to dislike the fact that I had a phone.﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ Then I started to wonder if I was wrong. ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ 课后课时作业（二） 128 写前导读：本文是一篇记叙文。文章讲述了作者12岁生日时，因为在学校表现非常出色，父母送给他一部手机作为生日礼物。后来，作者因沉迷于手机考试成绩一塌糊涂，作者拿着成绩单让妈妈签字，妈妈既生气又失望。意识到由于沉迷于手机使作者考试失败，作者的父母作何感想？作者接下来又是如何做的呢？ 课后课时作业（二） 129 [精彩范文] Realizing the reason for my failure, my parents started to dislike the fact that I had a phone. They said they had noticed that I never paid attention to them. It was like I had my own little world. So they thought we didn't communicate as much with my phone. They regretted having given me a phone, which made me ignore the family and study. 课后课时作业（二） 130 Then I started to wonder if I was wrong. A week later I tried going a whole day without a phone and it didn't go that badly. I had so much fun because I was actually spending time with my family and paying attention to them. From that day on, I had a different opinion towards phones. Phones really take me away from the rest of the world. I'm not saying that phones are bad and we should not use them, but we do have to spare some time to spend with our family and not get stuck with our phones all day. 课后课时作业（二） 131 精深阅读 Bangladesh has a large population. The nation depends on rice as its main food. Growing rice requires a lot of water and energy, especially during the dry season from January to June when farmers mostly rely on groundwater. This results in serious reduction of groundwater as well as greenhouse gas emissions (排放)． Researchers from the University of Washington and Bangladesh's Ministry of Agriculture have developed a system called Integrated Rice Advisory System (IRAS), which uses satellite data from NASA and its partners to give farmers important information. 课后课时作业（二） 132 IRAS works by combining satellite data on water use, rainfall, and weather forecasts with crop water demand characteristics to produce location－specific suggestions for farmers.
