(共10小题；每小题2分，满分20分)ALaptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1,500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e­mails to “speak” with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees — anywhere at all!Because of the many changes in computer technology, laptop used in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable (轻便的) computers can connect students to not only the Internet, but also libraries and other resources. State higher education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “Here we are in the middle of Virginia and we’re giving students a window on the world. They can see everything and do everything.”1. The main purpose of the laptop program is to give each student a laptop to ________.A. use for their schoolworkB. access the InternetC. work at homeD. connect them to libraries2. Why is the word “speak” in the second paragraph in quotation marks (引号)?A. They don’t really talk.B. They use the computer language.C. Laptops have speakers.D. None of the above reasons is correct.3. Which of the following is TRUE about Westlake College?A. All teachers use computers.B. 1,500 students have laptops.C. It is an old college in America.D. Students there can do nothing.4. “A window on the world” in the last paragraph means that students can ________.A. attend lectures on information technologyB. travel around the worldC. get information from around the worldD. have free laptops5. What can we infer from the passage?A. The program is successful.B. The program is not workable.C. The program is too expensive.D. We don’t know the result yet.[助读词汇]resource n. 资源powerful adj. 有力量的connect to 使与......连接have access to 接近in addition 另外be similar to 与......相似BI’m not so sure I like my friends any more. I used to like them— to be honest. We would have lunch, talk on the phone or exchange emails, and they all seemed normal enough. But then came Facebook, and I was introduced to a sad fact: many of my friends have dark sides that they had kept from me.Today my friends show off the more unpleasant aspects of their personalities via Facebook. No longer hidden, they’re thrown in my face like TV commercials— unavoidable and endless advertisements for the worst of their personalities.Take Fred. If you were to have lunch with him, you would find him warm, and self-effacing (谦逊的). Read his Facebook and you’ll realize he’s an unbearable, food-obsessed boring man. He’d pause to have a cup of coffee on his way to save a drowning man — and then write about it.Take Andy. You won’t find a smarter CEO anywhere, but now he’s a CEO without a company to run. So he plays Mafia Wars on Facebook. He’s doing well— level 731. Thanks to Facebook, I know he’s playing about 18 hours a day. Andy, you’ve run four companies— and this is how you spend your downtime? What happened to golf? What happened to getting another job?Take Liz. She is positive that the flu vaccine (流感疫苗) will kill us all and that we should avoid it. And then comes Chris who likes to post at least 20 times a day on every website he can find, so I get to read his thoughts twice, once on Facebook and once on Twitter.In real life, I don’t see these sides of people. Face to face, my friends show me their best. They’re nice, smart people. But face to Facebook, my friends are like a blind date which goes horribly wrong.I’m left with a dilemma. Who is my real friend? Is it the Liz I have lunch with or the anti-vaccine madman on Facebook? Is it the Fred I can grab a sand wich with or the Fred who weeps if he’s at a party and the wine isn’t up to his standards?1. Who is opposed to the flu vaccine in the passage?A. Fred.B. Andy.C. Liz.D. Chris.2. What is Andy probably busy doing now?A. He’s running his company.B. He’s playing golf all day.C. He’s looking for another job.D. He’s playing computer games.3. According to the passage, Facebook tends to ________.A. present another side of peopleB. offer some foods for freeC. show endless advertisementsD. get you to more parties4. What does the underlined “it” in the last paragraph refer to?A. a dilemmaB. my real friendC. FacebookD. Twitter5. The passage is developed mainly by _________.A. giving examplesB. following the time orderC. 1isting figuresD. raising questions[助读词汇]aspect n. 方面via prep. 通过unavoidable adj.不可避免的unbearable adj.难以忍受的pause vi. 暂停dilemma n. 困境keep from 隐瞒show off 卖弄food-obsessed 对事物上瘾的；吃货 a blind date 初次约会；相亲二、完形填空阅读下面短文，从短文后各题所给的A、B、C和D项中，选出可以填入空白处的最佳选项。

2021版高考英语一轮复习第一部分教材重点全程攻略Unit3Computers限时规范特训新人教版必修2Ⅰ.阅读明白得AWhile the world is still debating the safety of self­driving cars, Dubai is preparing to launch an autonomous flying taxi. Starting in July, the world's first passenger drone (无人机), the EHANG 184, will be available to passengers.The shuttle, released in Las Vegas in January 2021, weighs 440 pounds and can fly at heights of up to 11,500 feet. The egg­shaped vehicle has room for a single passenger weighing up to 220 pounds and a small suitcase. Though the flying taxi can reach speeds of up to 100 mph, it will typically operate at about 62 mph.Passengers can ask for the flying taxi to pick them up from appointed zones using a smartphone app. Passengers strap into the seat, select a destination on the touch screen, and enjoy the flight. To ensure the passenger's safety, all flights are monitored remotely by a control room on the ground.In the unlikely event that any of the components malfunction or disconnect, the drone will make an emergency landing to ensure the customer's safety. It's also programmed to ensure its route won't affect that of another drone. While having no control over the remotely piloted vehicle may appear scary, the producer, China­based EHANG, says, “It is the safest, smartest and eco­friendly low altitude autonomous flying vehicle.” Any drawback? The EHANG 184 has a battery life of 30 minutes and a flight range of just 31 miles. Also unknown is the cost of each ride.Though the flying taxi seems advanced, it is not the first driverless transportation option available to Dubai's residents. As part of its goal to have 25% of the public transportation automated by 2030, the authorities have built the world's longest driverless metro and introduced serf­navigating shuttles. Offi cials recently also partnered a US company to build supersonic speed pods to carry passengers between Dubai and Abu Dhabi.篇章导读：本文是一篇科普说明文，介绍了一种迪拜正预备投入供公交出租使用的自动驾驶低空飞行器——EHANG 184。

Book2unit3知识点在 Book2unit3 中，我们会接触到众多重要的知识点，涵盖了词汇、语法、阅读、写作等多个方面。

首先，词汇部分是英语学习的基础。

在这一单元，我们会遇到一系列新的单词和短语，比如“＿____”（单词 1），它常见的释义是“＿____”，常被用于“＿____”（相关例句）这样的语境中。

还有“＿____”（单词2），这个词有着“＿____”（释义）的意思，在“＿____”（例句）里能够很好地理解它的用法。

语法方面，重点之一是时态的运用。

例如，我们学习了过去完成时，它表示过去某一时间或动作之前已经发生或完成了的动作。

其构成是“had ＋过去分词”。

通过“＿____”（相关例句）这样的句子，能更清晰地理解其用法和意义。

另外，本单元的从句知识也值得关注。

比如宾语从句，在句子“＿____”中，“＿____”部分就是一个宾语从句，它起到了补充说明宾语内容的作用。

阅读部分，这单元的文章通常围绕着特定的主题展开，比如“＿____”。

在阅读过程中，要学会抓住关键信息，理解作者的观点和意图。

同时，注意文章中的逻辑关系和衔接词，像“however”“therefore”等，它们能帮助我们更好地跟上作者的思路。

写作方面，我们学会了如何描述一个事件或者经历。

要注意按照一定的顺序，比如时间顺序或者逻辑顺序，把事情的起因、经过和结果清晰地表达出来。

并且，要运用丰富的词汇和正确的语法结构，让文章更加生动和准确。

例如，在描述一次旅行时，可以这样写：“I had an unforgettable trip last summer First, I went to the beach The sun was shining and the sea wasso beautiful I swam in the sea and played volleyball with my friends Then,we had a delicious seafood dinner It was really a wonderful day”在学习 Book2unit3 的过程中，我们要多做练习题来巩固所学的知识，还可以通过阅读英语文章、观看英语电影等方式来提高英语的综合运用能力。
