篇章导读：本文是一篇议论文，主要描述了作者对生活的感悟，即努力过好每一天，珍惜眼下的生活。
1.them　考查代词。介词of后接人称代词的宾格形式。they的宾格为them。
2.limited　考查词性转换。此处limited和specified是并列关系，一起修饰time，所以填limit的形容词形式limited。
3.but　考查连词。句意：有时长达一年，有时短到24小时，但是我们总是对弄清楚垂死的人选择如何度过最后的时光或最后的几个小时感兴趣。根据语境可知，此处应用but表示转折。
4.discovering　考查非谓语动词。固定搭配be interested in后接名词或动名词作宾语。故填discovering。
5.what　考查宾语从句的连接词。动词wonder后的宾语从句中缺少动词do的宾语，所以用连接词what引导。
6.happiness　考查词性转换。感叹句中，what修饰名词，happy的名词形式为happiness。
7.as　考查固定搭配。句意：有时我想，把每天都当作生命的最后一天来度过也不失为一个很好的生命法则。as if是固定搭配，意为“似乎，好像”，符合语境。
8.sharply　考查词性转换。此处应用副词修饰动词stress。故填sharply，意为“大幅度地”。
9.were　考查虚拟语气。句意：我常常想，如果每个人在他成年的早期有一段时间处于眼盲、耳聋的状态，那会是一种幸事。根据句意可知，本句为虚拟语气。根据主句中的谓语动词“would be”可知，if从句中的谓语动词应用一般过去时，be动词一律用were。
10.more　考查形容词的比较级。appreciative是多音节形容词，本句表示“黑暗让他更加感激光明”，应用形容词的比较级形式，故填more。
Ⅳ.短文改错
Thanks for your concern in your letter about the smog which frequent strikes some areas of China. I'm also very worrying about such a terrible weather. It has brought much inconvenience or rather harm to people's health such as road accident, bad coughs and even lung cancers and so on.

Try to drive less and choose air­friendly products. Only when everyone had the environmental awareness can we have a blue sky. Hope to hear from you and share my good ideas.
答案：
Thanks for your concern in your letter about the smog which strikes some areas of China. I'm also very about such terrible weather. It has brought much inconvenience or rather harm to people's health such as road ， bad coughs and even lung cancers and so on.

Only when everyone the environmental awareness can we have a blue sky. Hope to hear from you and share good ideas.
难项分析：
第三处：去掉a　考查冠词。weather是不可数名词，不能和不定冠词搭配。故去掉a。
第七处：protect前加to　考查非谓语动词。句意：所以我们应该尽我们所能去保护它。此处用动词不定式作目的状语。故在protect前加to。
第八处：different→difference　考查固定搭配。make a difference为固定搭配，意为“有影响，起作用”。

课时作业
Ⅰ.阅读理解

(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：本文是一篇说明文。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。
1.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。
2.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。题干问的是“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。
3.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。
4.Where is this text most likely from？
A.A diary. B．A guidebook.
C.A novel. 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”等可推断，这篇文章是一篇科研报道，最有可能出现在杂志上。故选D。

(2020·内蒙古自治区奋斗中学高三月考)Many Android and iPhone owners use Google services on their mobile phones or tablets. One of the most widely used location services is Google Maps. When someone uses Google Maps, information about times and locations is recorded and stored.
Google also uses tracking tools with other services. Weather apps, for example, are designed to identify a user's location to provide local weather information. Even some Google Internet searches can result in the collection of information about exactly where a person was when the search was made.
Google says it collects the data to improve users' localized experiences. But such practices have also raised privacy concerns. Privacy activists have called on Google and other major technology companies to make it easier for users to turn off location services if they do not want to be tracked. In some ways, Google is clear about asking permission to use location information. For instance, Google Maps will seek approval from a user to give the app access to locations. If a user agrees to let Google collect location information over time, Google Maps will show this history in a “timeline” that shows the person's daily movements.
Google also has a “Location History” setting. The company says any user can turn off Location History at any time. And when Location History is turned off for a user's account, it is turned off for all equipment linked to that Google account. But the AP (Associated Press) found this does not appear to be true, finding that Google continued to save location history even if a user had turned off Location History.
Google states users can stop the saving of all location markers by turning off another setting, however, which is not clearly identified as being connected to location tracking. The setting is called “Web and App Activity”. It stores different kinds of information from Google apps and websites to a user's Google account.
篇章导读：本文是一篇说明文。文章讲述的是在关闭位置历史记录的情况下谷歌仍然在跟踪对象。
5.Why does the author mention Weather apps？
A.To advise people to stop using them.
B.To stress Google services are widely used.
C.To prove Google collects users' data illegally.
D.To show many apps can track a user's location.
答案：D　推理判断题。根据第二段中的“Google also uses tracking tools with other services. Weather apps, for example, are designed to identify a user's location to provide local weather information.”可知，谷歌还在其他服务中使用跟踪工具。作者提到Weather apps是为了说明许多应用程序可以跟踪用户的位置。故选D。
6.What is the voice from the privacy activists？
A.Users should use the Internet less.
B.Google should stop tracking users.
C.Google should respect users' privacy.
D.Google should turn off location services.
答案：C　推理判断题。根据第三段中的“Privacy activists have called on Google and other major technology companies to make it easier for users to turn off location services if they do not want to be tracked.” 可知，隐私维权人士希望用户在不想被跟踪的情况下可以很容易就关闭定位服务，他们主张“谷歌应该尊重用户的隐私。”故选C。
7.What does the author indicate in Paragraph 4？
A.The Location History setting is difficult to find.
B.The AP asks Google to remove Location History.
C.Turning off Location History can avoid being tracked.
D.What Google announces is hardly consistent with the fact.
答案：D　推理判断题。根据第四段中的“when Location History is turned off for a user's account, it is turned off for all equipment linked to that Google account. But the AP (Associated Press) found this does not appear to be true, finding that Google continued to save location history even if a user had turned off Location History”可知，即使用户关闭了位置，谷歌继续保存位置历史，所以谷歌所宣布的与事实并不相符。故选D。
8.Which can best summarize the passage？
A.Using Google puts you into a dangerous state.
B.Google services urgently need to get improved.
C.Google still tracks you with Location History off.
D.Web and App Activity has endangered people's life.
答案：C　主旨大意题。根据全文内容尤其是第四段中的“the AP (Associated Press) found this does not appear to be true, finding that Google continued to save location history even if a user had turned off Location History”可知，本文讲述的是谷歌仍然在关闭位置历史记录的情况下跟踪用户。故选C。
Ⅱ.七选五
(2019·全国卷Ⅲ)In an online class, developing healthy patterns of communication with professors is very important. __1__While I have only listed two of each, there are obviously many other situations that can arise. Students should be able to extend the logic (逻辑) of each to their particular circumstance.
Do's
•__2__Questions about subject content are generally welcomed. Before asking questions about the course design, read the syllabus (教学大纲) and learning management system information to be sure the answer isn't hiding in plain sight.
•Participate in discussion forums (论坛), blogs and other open­ended forums for dialogue. __3__Be sure to stay on topic and not offer irrelevant information. Make a point, and make it safe for others to do the same.
Don'ts
•Don't share personal information or stories. Professors are not trained nurses, financial aid experts or your best friends. If you are in need of a deadline extension, simply explain the situation to the professor. __4__
•Don't openly express annoyance at a professor or class. __5__When a student attacks a professor on the social media, the language used actually says more about the student. If there is truly a concern about a professor's professionalism or ability, be sure to use online course evaluations to calmly offer your comments.
A.That's what they are for.
B.Turn to an online instructor for help.
C.If more information is needed, they will ask.
D.Remember that online professors get a lot of emails.
E.Below are some common do's and don'ts for online learners.

G.Ask questions, but make sure they are good, thoughtful questions.
篇章导读：本文是一篇说明文。文章介绍了在选修网络课程时如何与授课老师建立健康有益的互动交流。
1.E　空格前句意：在网络课堂上，与授课老师建立健康的沟通模式是非常重要的；空格后句意：虽然“我”每个只列出了两条，但显然还有许多其他情况可能发生。下面的段落紧接着介绍了沟通的注意事项——两“做”和两“不做”，因此E项“下面是在线学习者应该做和不应该做的一些常见事情”符合语境。
2.G　此空位于句首，是对段落的总结。空格后句意：与主题内容相关的问题通常会受欢迎。在询问有关课程设计的问题之前，阅读教学大纲和学习管理系统信息，以确保答案不会隐藏在眼皮底下。由此可推知，此段表达要提出好的有水平的问题，故G项“问问题，但要确保这些问题是好的、深思熟虑的问题”符合语境。
3.A　上文建议参加论坛讨论、博客讨论和其他开放式讨论对话，举的这三个例子都是在线的讨论，并且可以帮助在线学习者，故A项“那就是它们的作用”符合语境。
4.C　空格前句意：如果你需要延长最后期限，只需向授课老师解释一下情况，故C项“如果需要更多的信息，他们会询问”符合语境。
5.F　空格前句意：不要公开表达对授课老师或课程的不满，由此可推知，后文应有对其不满的原因或具体说明，因此F项“每个人都曾经上过不太好的课”符合语境。

篇章导读：本文是一篇说明文。文章主要介绍了Uber公司正在研发飞行汽车，这种汽车操作噪声小、耗能低、污染少。
1.reality　考查词性转换。句意：飞行汽车可能很快成为现实。空格前有不定冠词“a”限定，空格处应用名词，因此用所给词real的名词形式reality。
2.to help　考查非谓语动词。ask sb. to do sth.是常用短语，意为“要某人做某事”。故填to help。
3.in　考查介词。固定短语in the future “在未来，在将来”。故填in。
4.which　考查定语从句的引导词。句意：Uber公司想利用一种体积小、完全由电力供能的飞行器，这种飞行器能像直升机一样在停车场上空起飞和着陆。空格处引导非限制性定语从句，指代先行词aircraft，在从句中作主语。故填which。
5.quieter　考查形容词的比较级。根据后面的连词“than”可知，此处用比较级形式。故填quieter。
6.was　考查动词的时态和主谓一致。此处描述的是过去发生的事情，应用一般过去时；主语flying cars表示的是一类事物，并结合空格后的“a ridiculous idea”可知，谓语动词应用第三人称单数形式。故填was。
7.But　考查连词。根据语境可知，此处表示转折，因此用But。注意首字母大写。
8.hiring　考查非谓语动词。句意：……我正在阅读关于Uber雇用一名美国航空航天局的工程师制造飞行汽车的消息……此处应用hire的动名词形式，作介词about的宾语。故填hiring。
9.flying　考查非谓语动词。这里应用v.­ing形式作定语，修饰cars。
10.themselves　考查反身代词。根据下文中的“but with human pilots”可知，此处指早期的飞行汽车不能自动飞行。故填反身代词themselves。

I am always dreaming about life in the future. What on earth will it be like？
Perhaps some people will go to the moon for a holiday, and some scientists will live under the sea. With plenty of educational programmes on the Internet, children needn't go to school every day; as a result, they can study at home. Maybe in the future each family will have a robot, which can do whatever they are told to, such as shopping and housework.
I do believe the dream will come true some day.
