avatars that have similar features to their personalities and that look more or less like them and act like them. 大多数人创造的虚拟形象都有着与他们性格相似的特征，看起来或多或少像他们，或者表现得像他们。 However, nearly all avatars are tall, young and nice­looking, so people obviously make their avatars look better than they do in real life. 然而，几乎所有的虚拟形象都是高挑的，年轻的和好看的，所以人们显然让他们的虚拟形象看起来比现实生活中的形象要好。 •They also experiment with things like

He'd hiked the park near his home in Southern California many times. But after adventuring along a new path last April, the 45­year­old mechanic was lost. He climbed to a spot, some 7，000 feet above sea level, where he found at least one bar of signal. “SOS. My phone is going to die. I'm lost，” he texted a friend, with a photo showing where he was. The shot showed his dirt­covered legs hanging over a steep waterfall of rocks. All he could do then was wait and hope. The temperature was dropping fast, and the winds were blowing. 课后课时作业（一） 112 Sixty miles away in Ventura County, Ben Kuo was working at home when he read a tweet, showing a grainy image of a man's legs. The search­and­rescue teams had spent the previous night unsuccessfully looking for Compean, so they posted the photo on social media, hoping someone might know the location. Kuo, then 47, works in the tech industry, and he has an unusual hobby: “I have always loved looking for where photos are taken，” he says. When he saw the blurry (模糊的) image of Compean's legs surrounded by an endless landscape of rocks and plants, he immediately pulled up a satellite map on his laptop. “There's an amazing amount of information you can get from satellites，” says Kuo. The first thing he noticed in Compean's photo was pieces of greenery. That finding narrowed his search, leading him to cross­referencing the photo with 3­D images of the area from Google Earth. The locations matched! Soon, a search­and­rescue team helicopter was in the air, hovering above Compean. 课后课时作业（一） 113 Days later, the two men met via Zoom, where they made a plan to meet in person. “I owe you my life.” he told Kuo. Compean's story probably would have ended very differently if Kuo, a total stranger, had not taken action. In fact, when Compean was finally pulled safely into the helicopter, one of his rescuers, unable to shout over the noise, wrote on a piece of paper, “You are so lucky.” 篇章导读：本文是一篇记叙文。文章主要讲述了Ben Kuo (本·郭)用卫星地图成功匹配出在野外迷路的Rene Compean (雷内·康潘)的位置，最终使Rene Compean得救。 篇章导读 课后课时作业（一） 114 1．What can we learn about Compean from the first two paragraphs？(　　) A．He was new to the forest so he got lost. B．He climbed high to get a phone signal. C．He tried to clean his legs by a waterfall. D．He was confident to be saved with his photo. 解析：推理判断题。根据第二段中的“He climbed to a spot ... bar of signal.(他爬到了海拔7，000英尺的地方，在那里他发现了至少一格信号。)”可推知，Compean爬到高处去接收电话信号。故选B。 答案 解析 课后课时作业（一） 115 2．What is the key factor in Compean's rescue？(　　) A．Good luck. B．A satellite map. C．A rescue helicopter. D．Technological skills. 解析：细节理解题。根据第四段中的“That finding narrowed his search ...

B．Kuo and a stranger. C．Compean and his friend. D．Compean and a rescuer. 解析：指代判断题。通读全文可知，Kuo使用卫星地图找到了 Compean的位置才使Compean得救，根据最后一段中的“I owe you ... he told Kuo.”可知，Compean告诉Kuo自己欠他一条命。由此可推知，“the two men”指的是Compean和Kuo。故选A。 答案 解析 课后课时作业（一） 117 B “You'll be blind by the time you're twenty­five，” a doctor at Children's Hospital predicted. “Your blood sugar is much too high.” It consumed me. No matter where I was or what I was doing, it was overhead like a dark cloud, just waiting for the right opportunity to destroy my world. I liked painting. Losing myself in painting filled me with peace. Painting provided me with the only place where I could escape from those threatening words. 课后课时作业（一） 118 When I was twenty­one, my right eye went blind. Precisely three months after my twenty­fifth birthday, I had a massive hemorrhage (大出血) in my left eye because of an accident. For the next twenty years, vision came and went. I went through many eye operations in an attempt to keep my vision. But after one final operation, I lost the battle and all remaining vision. And I buried all dreams of painting. Desperate, I enrolled in (注册) a sixteen­week program for the blind and visually impaired (受损的). I learned personal adjustment and the use of a computer with adaptive software. A whole new world opened up to me through this program. “JAWS and Window­Eyes are leading software for the blind，” my instructor told me. “You can use the Internet, e­mail and Microsoft with all its tools and features.” It's amazing! Hope went up for the first time in years. “By learning how to use hot keys to control the mouse, you can use Microsoft Access, Excel and Powerpoint，” my instructor added. 课后课时作业（一） 119 For the next several years, I learned that when one door closes, another door opens. There are plenty of choices available for the blind and visually impaired through the gift of technology. Not only do I have a speaking computer, but I have a speaking watch, alarm clock and calculator. 篇章导读：本文是一篇记叙文。文章讲述了作者因高血糖导致双目失明，从此放弃了酷爱的绘画。但是，他通过一个项目学习到适用于盲人和视力受损人员的电脑信息技术，再次燃起了对生活的希望。 篇章导读 课后课时作业（一） 120 4．What does the underlined word “it” in Paragraph 1 refer to？(　　) A．The right opportunity. B．Losing my sight in the future. C．Consuming too much sugar. D．The Children's Hospital. 解析：指代判断题。根据第一段第一句可知，医生预测作者会在二十五岁时失明；结合画线词所在句可知，无论作者身在何处，无论他在做什么，它就像乌云一样在头顶盘旋，仅仅等待着一个合适的机会来打破他的世界。据此可知，it指代“医生预测作者会在二十五岁时失明”这件事。故选B。 答案 解析 课后课时作业（一） 121 5．What happened when the author was about 25 years old？(　　) A．He gave up painting.

She searched online for certain information and made PowerPoint presentations. Wu Qiong, her classmate, was doing his chemistry homework carefully. But he couldn't work out the last problem even he tried his best. So he took out his mobile phone, opened a special app, and searched the problem. Solutions soon appeared on the screen in several seconds. Nowadays, many students do homework online with the help of the Internet. They search online, use apps or discuss through QQ and WeChat. “It’s convenient. You don’t have to wait for your teacher to explain it to you face to face，” according to Wu. “You can also learn by seeing how others work them out. What’s more, it improves students’ abilities. And it’s especially true for new kinds of homework. I am quite skilled at finding information online and using Microsoft Office.” 课后课时作业（一） 125 However, this trend (趋势) also causes problems. Some lazy students just copy the answers online without thinking. Even some ask their classmates to do homework for them. And their teacher may not know the fact. Anyhow, knowing how to use the Internet is important. The key is to have good self­control. When you come across a difficult problem, think about it by yourself first. Be sure to understand the reasons behind the answers after you have turned to the Internet, or you won't make progress. If you are not sure about your self­control, ask your parents for help. 篇章导读：本文是一篇说明文。文章介绍了网络对学习有很多好处，但是同时它也存在着一些问题。因此我们要学会正确地使用网络。 篇章导读 课后课时作业（一） 126 8．Both Li Ting and Wu Qiong used the Internet to ________．(　　) A．play games B．make friends C．take exams D．search information 解析：细节理解题。根据第一段中的“Li Ting, 15, from Shanghai, ... and searched the problem.”可知，李婷在网上搜索了一些西方节日的信息。她的同学吴琼拿出手机，搜索化学作业中的问题。由此可知，李婷和吴琼都使用互联网搜索信息。故选D。 答案 解析 课后课时作业（一） 127 9．According to Wu, he thinks ________．(　　) A．the new learning way is difficult B．students should use the new learning way C．students should study with the teacher face to face D．students can copy others' homework online 解析：推理判断题。根据第三段中的“It's convenient ... it improves students' abilities.”可知，吴琼认为上网搜索问题的解析就不用等待老师的解释，也可以通过观察别人如何解决这些问题来学习。更重要的是，它提高了学生的能力。由此可推知，吴琼认为学生们应该采用这种新的学习方式。故选B。 答案 解析 课后课时作业（一） 128 10．When a student uses the Internet, he must ________．(　　) A．have an app B．have a mobile phone C．ask his parents for help D．have good self­control 解析：细节理解题。根据最后一段中的“Anyhow, knowing how to ... good self­control.”可知，当一个学生使用互联网时，他必须有良好的自制力。故选D。 答案 解析 课后课时作业（一） 129 11．What's the main idea about the passage？(　　) A．How to learn a language.

For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as dangers and with good guides, some education, and a few precautions (预防措施), the wilds of the Internet can be safely navigated (航行). “Kids have to be on­line. If we tell our kids they can't have access to the Internet, we're cutting them off from their future，” said an expert. 课后课时作业（一） 131 Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way to limit access would be to use what is known as a “content screener (过滤器)”. But this can't be wholly reliable (可靠), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet. 课后课时作业（一） 132 A few other tips Don't put the PC in a child's room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity. Ask your child what he or she has been doing and about any friends they make on­line. Tell your child not to give on­line strangers personal information, especially like address and phone number. And tell your children never to talk to anyone they meet on­line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along. 篇章导读：本文是一篇说明文。文章讲述了因特网对孩子既有利也有害，并告诉父母应该如何保护他们的孩子远离那些不适合孩子的网络资料。 篇章导读 课后课时作业（一） 133 12．The best way to protect children from improper material is ________.

B．Children's not having access to Inter net may have effect on their progress. C．Using a content screener is most reliable for keeping children having access to Internet. D．Searching engines can help children to select materials fit for them. 解析：细节理解题。根据第二段中的“If we tell ... from their future”可知，如果我们不允许我们的孩子接触网络，会影响他们的将来。故选B。 答案 解析 课后课时作业（一） 135 14．According to the passage, we can infer that ________．(　　) A．softwares fit for children who want programming B．a child who is on­line is in danger C．Internet is a jungle full of danger D．Internet contains a lot of harmful sites 解析：推理判断题。根据第三段中的“Many of them ... your kids to go.”可知，有一些网站是不能让孩子们上的，由此可推知，网上有一些有害的网站。故选D。 答案 解析 课后课时作业（一） 136 15．The passage is mainly about the subject of ________．(　　) A．American children going on­line B．Internet in America C．appreciating Internet D．opposing children's on­line 解析：主旨大意题。通读全文并结合第一段可知，本文说明了美国孩子的上网问题。故选A。 答案 解析 课后课时作业（一） 137 课后课时作业（二） 较易题(占比50%)　中档题(占比25%)　拔高题(占比25%) 题号 Ⅰ Ⅱ Ⅲ Ⅳ 难度 ★★ ★ ★ ★★★ 课后课时作业（二） 139 Ⅰ　阅读 Washington, D．C.

Long gone are the days of dial­up and waiting for your turn to use the computer. It's easier than ever to connect to the Internet in the digital world today. 1(____) Wi­Fi is a wireless network that uses radio frequency signals to connect to the Internet or send messages between devices without wires. Everything from your phone and laptop to tablets and printers can use Wi­Fi, thanks to these waves. 2(____) Two years later, a group of companies formed the Wireless Ethernet Compatibility Alliance (now the Wi­Fi Alliance), a global non­profit organization created to promote the new Wi­Fi standard. 课后课时作业（二） 146 None of that history explains what Wi­Fi stands for, because the phrase doesn't stand for anything. Wi­Fi is a trademarked term describing the device or technology based on the Institute of Electrical and Electronics Engineers wireless communication standard 802.11, according to the Wi­Fi Alliance. 3(____) So the Wi­Fi Alliance hired the marketing company Interbrand to come up with a shorter name: Wi­Fi, according to one of the founding Alliance members. 课后课时作业（二） 147 4(____) The rumor that it stands for “Wireless Fidelity (无线保真)” is thanks to the Alliance. Some members didn't understand the branding or marketing for Wi­Fi. They felt consumers would want an explanation for the name. So the Alliance agreed to include a tagline: The Standard for Wireless Fidelity. That's why so many people assume Wi­Fi stands for wireless fidelity, but the tagline came after the name. 5(____) Don't add to the confusion and stop associating these phrases by learning the real meaning behind these acronyms. A．That's a mouthful. B．This is mostly thanks to Wi­Fi. C．The name caused a misconception about Wi­Fi. 课后课时作业（二） 148 D．There is some debate surrounding the question what Wi­Fi stands for. E．In 1997, a committee of industry leaders approved a common Wi­Fi standard. F．Several years ago, a common standard of Wi­Fi was set up by several companies. G．Plus, the Alliance removed the tag, although the confusion it brought still lives on today. 篇章导读：本文是一篇说明文。在当今的数字世界，上网比之前更加容易，这主要感谢Wi­Fi，本文介绍了什么是Wi­Fi。 篇章导读 课后课时作业（二） 149 1．答案： B 解析：根据第一段前两句可知，拨号上网的日子早已成为过去，如今和以往相比更容易连接网络，且设空处下文紧接着介绍了Wi­Fi的相关内容，由此可知，B项(这主要多亏了Wi­Fi。)承上启下，符合语境。故选B。 答案 解析 2．答案： E 解析：根据设空后一句可知，两年后，几个公司成立了无线以太网兼容性联盟，目的是推广新的Wi­Fi标准。与新的标准相对应则是一般的、普通的标准，E项(1997年，行业领导者委员会批准了通用Wi­Fi标准。)引出下文，且E项中的“a common Wi­Fi standard”与设空后的“new Wi­Fi standard”对应。故选E。 课后课时作业（二） 150 3．答案： A 解析：根据设空前“Wi­Fi is a trademarked ... to the Wi­Fi Alliance.”可知，根据Wi­Fi联盟的说法，Wi­Fi是一个商标术语，用来描述基于IEEE无线通信标准802.11的设备或技术，下文表明Wi­Fi联盟聘请了营销公司Interbrand，为它起了一个短一点的名字：Wi­Fi；由此可知，A项(那个(名字)又长又拗口。)符合语境。故选A。 答案 解析 4．答案： D 解析：根据下文中的“The rumor that”和“Some members didn't understand”可推知，人们对于Wi­Fi是什么这个问题还有一些争议。D项(围绕Wi­Fi代表什么的问题存在一些争论。)引出下文。故选D。 课后课时作业（二） 151 5．答案：G 解析：根据上文“So the Alliance ... after the name.(因此，联盟同意加入一个标签：无线保真标准。这就是为什么很多人认为Wi­Fi代表无线保真，但标签却出现在名称之后。)”可知，G项(而且，虽然该联盟去除了这个标签，但它带来的困惑到现在仍然存在。)承接上文，符合语境。故选G。 答案 解析 课后课时作业（二） 152 Ⅲ　语法填空 Last month my uncle called me and he said he __1__ (visit) me with his family soon.

He was therefore able to drive home every day for lunch. Every time he drove home in the middle of the day, he found cars were parked in the road outside his house, and there was no room for his own car. He had to drive two blocks farther before he could find a place to park. Then he had to walk home. This made him very angry. He had put up a board which read “No Parking！” in the garden facing the road, but nobody seemed to pay attention to it. People only obeyed a police notice, but not a private one. There were no parked cars where there was a blue board with white letters on it: Police Notice—No Parking! 课后课时作业（二） 161 Mrs Brown suggested that he should steal a police notice. But he dared not, being afraid of going to prison. She then suggested that he make one just like a police notice. He said he was not a policeman and couldn't use the word “police”. He decided that he must find a way out and started thinking hard. For several days, the smell of paint filled the house. One night he showed his wife a new notice board. It was painted in white letters on a blue board: Polite Notice—No Parking! “Oh，” Mrs Brown said, “but you told me you weren't going to use the word ‘police’. That's exactly like a police notice.” “Is it？” he asked. “Look again.” She began to laugh, “You are really rather clever.” 课后课时作业（二） 162 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。 Why did Mrs Brown say her husband was really rather clever？﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ If the police discovered that the Browns were using a police notice, ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ 课后课时作业（二） 163 写前导读：本文是一篇记叙文。文章讲述了Mr Brown (布朗先生)每天中午回家吃饭的时候，家门口前总是停满了车，因此他不得不把车开到其他地方，然后走路回家。这对他来说是一个难题。他贴了一张“No Parking”的广告牌没人理会。后来，他换了一张广告牌 。他的妻子为什么会夸他聪明？如果警察发现了布朗先生的广告牌，会处罚他吗？ 写前导读 课后课时作业（二） 164 [精彩范文] Why did Mrs Brown say her husband was really rather clever? Because she found that he had written a notice which looked exactly like a police notice. He made a blue board with white letters on it, but it was not a real police notice. Being afraid of going to prison, Mr Brown certainly dared not use the word “police”， but he used “polite notice” instead of “police notice”. He was quite clever, wasn't he? If the police discovered that the Browns were using a police notice, they would feel angry and punish them. It was a crime because he offended the police, passing himself off as a policeman. But Mr Brown remained very calm. He would ask the policemen to look at the board carefully. The policemen would burst out laughing when they realised what had happened. 答案 课后课时作业（二） 165 R $$
