高考英语一轮复习课时作业详答8：Unit 3《Computers》(新人教版必修2通用)
课时作业(八)Ⅰ.1.D考查交际用语。
句意为：“很抱歉，我未能按时完成它。
”“无论如何我还得谢谢你。
”D项符合语境。
A项为见面打招呼用语；B项在表示委婉拒绝时用；C项在表示非常感谢时用，均不符合句意。
2．C考查副词辨析。
句意：也许，从现在起他真应该多锻炼。
不管怎样，我希望他能很快恢复过来。
somehow “由于某种原因”；somewhat “有点；稍微”；anyway “不管怎样；无论如何”；anywhere “在任何地方”。
故C符合题意。
3．A watch over “照管”。
句意为：我去游泳，你帮我看一下衣服好吗？其他选项均不符合句意。
4．B考查短语辨析。
出了重大事故放长假，也就是说(换句话说)，他被开除了。
前后句子从逻辑上讲不存在因果关系或者转折关系。
5．A考查动词的时态和语态。
Italian Luca Parmitano 和select 是被动关系，故排除B，C。
根据句意，表示过去的动作“已经被选入……”对现在的影响，故用的是现在完成时的被动语态，故选A。
6．A考查交际用语。
由答语中的not me可以看出，他不想去，所以选择A项，这是一句美式俚语，意为“我不喜欢这个东西”或者“它不适合我”。
7．D考查词汇辨析。
as作“随着”解为连词，引导时间状语从句。
with 是介词，不能引导从句。
8．A考查时态、语态和主谓一致。
答话人之所以让对方删除手机上要求汇款的信息是因为到目前为止已经有很多人上当受骗，所以用现在完成时的被动语态，排除C、D两项；many a表示“大量”，修饰单数可数名词，谓语动词用单数，故排除B项选A项。
9．C考查as a result的用法。
as a result意为“因此，所以”，单独使用，表示后句是前句的结果；而however表示转折，moreover, furthermore表示递进，不符合语境。
10．D考查such a＋adj.＋n＋that结构。
注意，如果把A项中的a 放到well-known后也是正确的。

would not test medicines on animals.Such experiments are stressful and sometimes painful for animals，and expensive and timeconsuming for people.Yet animal experimentation is still needed to help bri dge vast gaps in medical knowledge.That is why there are some 50 to 100 million animals used in research around the world each year.Europe，on the whole，has the world’s most restrictive laws on animal experiments.Even so，its scientists use some 12 million animals a year，most of them mice and rats，for medical research.Official statistics show that just 1.1 million animals are used in research in America each year.But that is misleading.The American authorities do not think mice and rats are worth counting and，as these are the most common laboratory animals，the true figure is much higher.Japan and China have even less comprehensive data than America.Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs.Alternatives to animal testing，such as using human tissue or computer models，are now strongly recommended.In addition，sharingall research results freely should help to reduce the number of animals for scientific use.At present，scientists often share only the results of successful experiments.If their findings do not fit the hypothesis being tested，the work never sees the light of day.This practice means wasting time，money，and animals’ liv es in endlessly repeating the failed experiments.Animal experimentation has taught humanity a great deal and saved countless lives.It needs to continue，even if that means animals sometimes suffer.Europe’s new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.1．What is the main idea of this passage?A．The success of animal experiments should be ensured.B．A ban on the use of animals in the lab should be enforced.C．Greater efforts need to be taken to reduce the number of lab animals.D．Scientists should be required to share their research results with each other.2．Which of the following statements is true about animals used in the lab?A．America uses only about 1.1 million lab animals per year.B．Europe does not use mice and rats as lab animals at all.C．Britain does not use as many lab animals as China does.D．Japan has limited data on the number of lab animals used each year.3．Which of the following is mentionad as an alternative to replace animal experiments?A．Statistical studies.B．Computer models.C．DNA planted in animals.D．Tissue from dead animals.4．What usually happens to unsuccessful animal experiments?A．They are not revealed to the public.B．They are made into teaching materials.C．They are collected for future publication.D．They are not removed from the research topic list.Ⅳ.短文改错(2013·河北衡水中学高三上学期二调考试)I am Li Hua，a Chinese student taken summer courses in your university.I am writing to ask for help.I come here last month.I find my courses

Unit 3 ComputersⅠ.阅读理解AAll over the world mothers and fathers teach their children manners.Other children may have manners that are not like yours.There are all kinds of manners.Many years ago，children who had good manners were seen and not heard.They kept quite quiet if grownups were talking.T oday，wellmannered children have more freedom.Sometimes good manners in one place are bad manners in other places.Suppose you are a visitor in the land of Mongolia.Some friends ask you to eat with them.What kind of manners do they want you to have？They want you to give a loud “burp(打嗝)”after you finish eating.Burping would show that you like your food.In some countries，if you give a loud burp，you are told to say “Excuse me，please.”In many places people like to eat together.But in some parts of Polynesia，it is bad manners to be seen eating at all.People show good manners by turning their backs on others while they eat.What are manners like in an East African town? The people try not to see you.They are being polite.You may see a friend.He may not see you at all.If you are polite，you will sit down beside him.You will wait until he finishes what he is doing.Then he will talk to you.Suppose you visit a friend in Arabia.You should walk behind the other tents until you come to histent.If you pass in front of the other tents，you will be asked into each one.The people will ask you to eat with them.And it is bad manners if you say no.Manners are different all over the world.But it is good to know that all manners begin in the same way.People need ways to show that they want to be friends.[语篇解读] 本文主要介绍了世界上一些地方的礼仪。

Online computer game centers exist in many cities and towns throughout Asia. Facing the pressures of school and life, people tend to the virtual world, expecting a diversion from these problems. Too often, however, they can lead to problems and unhealthy addictions.This is most clearly seen in the example of South Korea. The country has the world's highest percentage of highspeed Internet services. It also has a high number of online game players and related problems. It was once reported that a young man collapsed (突然晕倒) and died while playing online games. He had been playing almost nonstop for 86 hours at an Internet cafe. Another young man killed his sister after becoming confused between the online world and real life. A12yearold boy stole $16，000 from his father and ran away from home. He did this to continue his obsession (着迷) with online games. Such problems, however, don't just happen in South Korea. They are spreading to other parts of Asia, as well.What kinds of people develop online game addiction? What does the problem look like? Dr SueHuei Chen, a clinical psychologist, researches Internet addiction. She discovered s ome signs of atrisk individuals such as lack of friendship and good social skills. Those problem individuals feel it so compulsive to play online games that they could sacrifice things such as school and family. They feel the need to spend more and more time online. And they become upset if anyone tries to limit their online game playing.How many problem game players are there? In mainland China, the potential number of problem online gamers is alarming. Just in 2004, China has had 13.8 million online game players according to China Daily. Furthermore, it stated that 80 percent of these were under 25 and had signs of addiction. Such numbers point towards a growing problem among Chinese youth.Make sure to keep control over your online game playing. If you don't control it, it can get control of you.16．The underlined word “diversion” in the first paragraph is closest in meaning to ________．A．solution B．comfortC．escape D．support17．The examples in the second paragraph tell us that ________．A．the side effects are caused by highspeed Internet servicesB．online game playing can even cause deathC．online games have caused much damage to young peopleD．the teenage boy can't resist the temptation of the online games18．According to Dr SueHuei Chen, what can we do to prevent game addiction?A．Limit the speed of the Internet services.B．Sacrifice things such as school and family.C．Spend more and more time online.D．Care much for the young and improve their ability to get along with others.19．We can conclude from the passage that ________．A．the demand for online services continues to growB．China is fighting a battle against online gamesC．the problems caused by online games don't just exist in South KoreaD．in the year 2004 there were a total of 13.8 million Chinese visiting the Internet20．What's the best title for the passage?A．Internet ProblemB．Addiction to Online GameC．Problem People in the WorldD．Online Game Can Control PeopleBSince the 1970s, scientists have been searching for ways to link the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines.Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's thoughts.In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles，” Tavella says. “O ur system allows disabled people to communicate with external world and also to control devices.”The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelcha ir.”He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.21．BCI is a technology that can ________．A．help to update computer systemsB．link the human brain with computersC．help the disabled to recoverD．control a person's thoughts22．How did Tavella operate the wheelchair in the laboratory?A．By controlling his muscles.B．By talking to the machine.C．By moving his hand.D．By using his mind.23．Which of the following shows the path of the signals described in Paragraph 5?A．scalp→computer→cap→wheelchairB．computer→cap→scalp→wheelchairC．scalp→cap→computer→wheelchairD．cap→computer→scalp→wheelchair24．The team will test with real patients to ________．A．make profits from themB．prove the technology useful to themC．make them live longerD．learn about their physical condition25．Which of the following would be the best title for the text?A．Switzerland, the BCI Research CenterB．New Findings about How the Human Brain WorksC．BCI Could Mean More Freedom for the DisabledD．Robotic Vehicles Could Help to Cure Brain Injuries课时作业(八)Ⅰ.本文是“我”外出购物时的一次尴尬的经历。

Unit 3 ComputersⅠ.阅读理解Today I want you to know Sadness can be a good friend.“All well and good，Master Yoda，” you say，“but how does that work？”First，Sadness is about losing something you care about，whether that's a loved one，a job，or a football game...So，Sadness shows you what you care about.Would you feel sad if your girlfriend / boyfriend left？The answer tells you how attached you are to this person.Along the same lines，experiencing the Sadness of loss helps us to appreciate what we still have.Funerals are painful occasions，and they are great for bringing people back together，burying old conflicts，healing wounds，but it only works if you show up and feel the Sadness and let it bring you together with the others there.One who can't bear Sadness will tend to shy away from love，commitment，and real passion，in order to avoid grief，and that's an empty life.Similarly，losing a job can help you appreciate that you still have your health.Losing your health can bring loved ones together.Losing money can help you to focus on what really matters to you，your values，your sense of mission，your spirituality.Lastly，Sadness has authenticity to it.Grieving has a way of slowing you down and bringing you back to the moment.It forces you to let go of your worries about your t odo list and next quarter's numbers and your fastpaced life and really be with yourself，your feelings and the people around you.This is important today because we can get so lost in our smart phones and emails and lose sight of people，relationships，and dreams.So，Sadness is the kind of friend who can help you to stay grounded and real，to honor what's important and let go of what's not，and we all need that kind of friend.1．The best title for the text would be________.A．Why Sadness Is Your FriendB．How Sadness Works in Your LifeC．What Do You Think of SadnessD．Why You Feel Sad2．How many reasons why Sadness can be a friend are mentioned in the text?A．Only one. B．Two.C．Three.

高考英语一轮复习Unit3Computers学案新人教版必修2Unit 3 Computers电脑晨读・记忆 ComputersThe goal of early calculating machines was to simplify difficult sums. But with the help of new technology, electronic chips replaced tubes and a revolution of artificial intelligence has arisen. From then on, the appearance of computers totally changed our lives. They can not only download information from the web when connected by the network or mobile phone signals, but also solve different types of logical problems. With operators as their coaches,they can even control rockets to explore the moon and instruct androids withthe human race’s characters to mop floors and watch over your naughty niece. Anyhow, computers are so helpful that they do bring happiness.However, computers are easily attacked by viruses. This reality has become a hard-to-deal with-problem. As a result, computers are dangerous in a way. So, personally, I worry about their universal applications in some fields, such as finance.电脑早期计算机器的目的是简化比较难的计算。

Unit 3 ComputersⅠ.阅读理解A(2018·吉林长春检测)Electronic books have changed the way many people read for pleasure.Now online textbooks are changing the way some students learn and some teachers teach.More than one hundred and seventy-five thousand students attend the public schools in Fairfax County,Virginia,outside st year,the school system used digital(数字的) books in fifteen schools.This school year,middle schools and high schools changed from printed to electronic textbooks in their social stu dies classes.Luke Rosa is a history teacher at Falls Church High School.His students work on laptop computers at school.He explains the idea to them this way,“I mean,it’s just like a regular textbook,except it’s got it all,online.”Peter Noonan,an assistant superintendent(助理监督) of schools,said,“The world’s changing.And the online textbooks can change r ight along with the events that are happening.” Digital books also cost less than printed textbooks,he said.A student named Melanie Reuter said,“I don’t h ave to carry a textbook around,so that’s nice.”But another student said,“I don’t like it because the Internet sometimes doesn’t work.”Students also need access to the Internet when they are not at school.About ten percent of students in Fairfax County do not have a computer or online access at home.Public libraries in the county have free Internet.There are also after-school computer labs as well as computer clubhouses supported by the county.Middle school student Slieman Hakim is happy about that.He said,“My family only has one computer;my sister and I both do our homework on it.So I come here to do my homework.It’s good.”Other school systems in the area are also considering online textbooks.1.Which of the following is NOT used when students have social studies classes?puters.B.The Internet.C.Paper textbooks.D.Electronic textbooks.2.One of the disadvantages of digital textbooks is that .A.they’re more expensiveB.they can’t be used if the computer is offlineC.they’re soon ou t of dateD.reading online does harm to students’ eyes3.Why does Slieman Hakim feel happy?A.He is offered a free computer to do his homework.B.He doesn’t have to do his homework at home.C.He has access to the Internet to study at any place.D.He needn’t share a computer with his sister to do homework.4.What can we learn from the passage?A.All students like digital textbooks because they are new.B.Digital textbooks are more beautiful than paper textbooks.C.Students can do their homework in the computer clubhouses.D.The lessons online are completely different from those in paper textbooks.〚导学号23280038〛B(2018·陕西西安中学期中检测)The Internet plays a big part in human life.We use it for work and entertainment.We can find new recipes on the Internet or advice on staying healthy.We can even use it to learn a new language.We use the Internet to keep in contact with family and friends and stay in touch with issues we care about.The list goes on and on.So,there may be no going back to an Internet-free life.But can using the Internet too much be bad for our health?It might be,say researchers.A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group—teenagers.So,try to be a responsible guardian(监护人).The study results show that teens who spend at least 14 hou rs a week online were more likely to have high blood pressure.High blood pressure makes your heart and blood vessels work too hard.Over time,this extra strain increases your risk of a heart attack or stroke.High blood pressure can also cause heart and kidney disease.It is also closely linked to some form of dementia(痴呆),or a brain disease.The Henry Ford Hospital in Detroit,Michigan did the study.It involved 335 young people,from 14 to 17 years old.One hundred and thirty-four of the teens were described as “heavy Internet users”.Researchers found that out of these 134teens,26 had high blood pressure.The researchers say the study is the first one to connect heavy web use with high blood pressure.Other research has connected that heavy Internet use with health problems including anxiety,depression and obesity.The lead researc her of the study is Andrea Cassidy-Bushrow.For the purpose of the study,she explains,teens considered heavy Internet users were online on average 25hours a week.It is important for teens to take regular breaks from their computers or smartphones and to do some kind of physical activity.She also suggests that parents limit their children’s use of the Internet to two hours a day,five days a week.The Centers for Disease Control and Prevention(CDC) says,70 million,or 29%,of American adults have high blood pressure.The CDC estimates that high blood pressure costs the United States $46 billion each year.5.The author mai nly wants to tell us .A.how to prevent high blood pressureB.too much Internet use may be bad for teenagersC.it’s necessary for teenagers to avoid the InternetD.heavy Internet use will worsen teenagers’ memory6.The first paragraph of the text is used to.A.introduce the topicB.analyze the causesC.offer some opinionsD.make some suggestions7.According to Cassidy-Bushrow,teenagers’ use of the Internet should be limitedto.A.25 hours a weekB.2 hours a weekC.10 hours a weekD.5 hours a week8.The text is mainly intended for .A.parentsB.teachersC.web-designersD.students〚导学号23280039〛Ⅱ.七选五阅读Speaking is not equal to learning1.You don’t need to study grammar too much.The first suggestion may sound strange to many students who begin to learn English,but it is exactly important. 1 However,if you want to speak fluently,you should try to speak English without thinking too much of grammar.Studying grammarwill only slow you down and make you hesitate.You will think about the grammar rules instead of naturally saying a sentence like a native.2.You can’t translate every word.When you try to speak English,you do not need to translate every word from your mother tongue. 2 Another problem you may meet is that you will misuse grammar rules that you have learned in your mother language.3. 3The reason why many people can learn well is that they often practise.But in order to speak English fluently,you need to practise speaking.When you study,don’t just listen.Speak out loud the material you are listening to and practise what you hear.Practise speaking out loud until your mouth and brain can do it without any effort. 44.You should study correct material.A phrase you often hear is,“Practice makes perfect.” This is not completelytru e.Practice only makes what you are practising permanent.If you practise the incorrect sentence,you will have perfected saying the sentence incorrectly. 5A.You should try to speak fluently.B.You need to practise speaking what you hear.C.By doing so,you will be a ble to speak English fluently.D.If you want to pass examinations,you should study grammar well.E.If you listen more,you can speak correctly and fluently sooner or later.F.Therefore,it is important that you study material that is commonly used by most people.G.The order of words is probably completely different and you may be both slow and incorrect by doing this.〚导学号23280040〛Ⅲ.书面表达(2018·河北滦南一中期中检测)假定你是李华,你校外事处招募暑假“志愿家庭”,接待来你市参观访问的美国中学生代表。

You roll over, smiling as you come across a swimming pool filled with chocolate. And then, your wonderful dream becomes a nightmare(噩梦) when someone is screaming, “Get up！” It's just what every teenager goes through each morning!Now, there seems to be one school that finally understands that requiring teens to show up at 9 am is not just cruel but also harmful to both the kids and the school.Monkseaton High School in North Tyneside, Britain, recently decided to experiment to see if there is any difference in student behavior if they just pushed back the start of their day by one hour, from 9 am to 10 am. And the results are surprising.Since carrying out the later start, Monkseaton has seen a 28% drop in truancy,_even hardly any lateness, and best of all, higher test scores. One of the reasons is that the teenagers are much happier to have the extra hour of sleep, but there is also a scientific reason behind why they need the extra sleep.The school's decision to push back the time was based on the research done by Oxford Professor Russell Foster, who pointed out that teenagers and adults have different sleep cycles，explaining why teenagers go to bed late and wake up late.While adults are wide awake and ready at 8 am, teenagers are not fully awake until 10 am, sometimes even noon. Teachers may argue that their students perform better in the morning, but in fact, it is because they are in the zone while their students are still sleepy, making the students easier to control.Memory tests prove that the more difficult classes should be in the afternoon when teenagers are most wide awake.The Monkseaton school officials are encouraged by the results and plan on voting to make it a permanent change.31．What's the meaning of the underlined word “truanc y”？A．Grades. B．Classes.C．Absence. D．Practice.32．What can we learn from the passage?A．Teenagers and adults have the same sleep cycle.B．Teenagers are fully awake at 10 am as a whole.C．Teenagers are much happier to sleep than study.D．Teenagers need the extra sleep also for a scientific reason.33．Which of the following statements is NOT true according to the passage?A．Monkseaton High School is satisfied with the result of the experiment.B．It is very cruel for the teenagers to show up in class at 9 am every day.C．Monkseaton High School plans to change the school time forever.D．In fact, teenagers perform better in the morning than in the afternoon.34．What's the best title for this passage?A．Get up early, teenagers!B．Finally, a school understands teenagersC．Why do teenagers stay up late?D．Differences between teens and adultsⅣ.完成句子35．Scientists ____________________ the cure for AIDS for the last 20 years. (explore)在过去的二十年里，科学家们一直在探索治愈艾滋病的方法。

B(2018·合肥市高三调研性检测)Social networks are a big part of nearly every teenager's life in this day and age. Many teens have QQ, WeChat, or Weibo but little do a lot of teens know that they can be held responsible for everything they post for the rest of their lives. Everything you post online is part of a digital footprint that can always be traced (追踪) back to you. That includes every post, even every like, comment, favorite and forward that you have ever committed. All pictures you've posted or will post have been stored in a digital database, and it is the companies' right to keep all of these documents that you believe to have been deleted or hidden.With every post comes a consequence; whether it is good or bad，what you post could be seen by anyone. That is why you have to be very careful of what you decide to post or comment.If you think you are safe from Servite finding out about one funny comment you made six months ago on a meaningless picture, you are probably wrong. Recently, a senior, Aaron, at Servite learned this lesson the hard way this year. He wrote a series of ugly comments towards Connelly girls on a web page, ignoring potential consequences.This student, however, did have to face consequences from Servite as he was removed from all of his leadership roles in the school. Surprisingly enough, he fully agreed with his punishment handed down by the administration and fully understood why he was given such severe discipline (处罚)．“When you agree to come to Servite, you are agreeing to defend what Servite stands for，” the young man said. “That continues from 8 am to 2 pm. It's at all times.”So, next time you're about to post something you think could be received as offensive or inappropriate, think twice, or don't press the “Send”．【文章大意】本文是一篇议论文。
当下很多青少年拥有微信、QQ、微博等网络社交工具，但是他们很多人都不知道要对自己所发布的内容负责。
文章通过一名高中生的事例说明，在网上发布信息应当慎重。
4. What does the author think the teens should do in the first paragraph?A．Avoid using social media.B．Remove their own digital documents.C．Be responsible for what they put online.D．Learn to balance their online and offline time.答案与解析：C'考查细节理解。
