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。

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。
