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。

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. D．Five.3．The fourth paragraph is developed mainly by________.A．providing the examplesB．telling personal experiencesC．making comparisonsD．listing facts4．The word “It” in the last paragraph but one refers to________.A．Letting go of your worriesB．Bringing you back to the momentC．GrievingD．Fast­paced life答案：[解题导语]本文是一篇议论文。

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。

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.

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。

And 160 researchers join in the project. The university's researchers made an agreement with the European Commission. The work may try to make “multi－modal interfaces (界面)”which allow machines to sense and respond to the moods of the user.Programme coordinator (协调者) Professor Roddy Cowie said while it sounded like science fiction，computers which responded to human feelings would appear.“At the moment，our use of computers is limited by the fact that we need a keyboard and a screen to access(使用) them，”he said.“But feelings are part of normal speech, and experience has s hown that most users are deeply uncomfortable with speech interfaces that ignore them－too uncomfortable to use them very much.”“If we can make computers more expressive, and also less challenging to use，there is a great chance to let people make full use of information technology.”The emotion－sensitive computer would have its own “personality” and build a social relationship with the user.“It's a fair bet that in 30 years' time, emotion－sensitive interfaces will be as much part of life as windows and mouse interfaces are now，”said Professor Cowie.The project team believes such computers would play an important part in teaching and learning.1．What does the passage mainly tell us?A．Researchers at Queen's University have completed a project.B．The research for an emotion－sensitive computer is being led by a Northern Ireland team.C．160 researchers have joined in the 10 million－euro project for a thinking computer.D．Computers are playing a more and more important part in our daily life.2．It can be learned from the passage that ________．A．an emotion－sensitive computer has been invented and is being put into use B．an emotion－sensitive computer cannot respond to the moods of the user C．an emotion－sensitive computer has not been invented by the teamD．the research for an emotion－sensitive computer has not gained people's support3．What does Professor Roddy Cowie think of the emotion－sensitive computer?A．He thinks it is only a part of science fiction.B．He thinks it is worth the research and it is easy to produce.C．He believes it is impossible for the team to invent the emotion－sensitive computer.D．He believes it can come into being.4．In Professor Roddy Cowie's opinion，________ limits our use of computers.A．the fact that a keyboard and a screen are needed to use computersB．the fact that we don't know much about computersC．the fact that feelings are part of normal speechD．the fact that the emotion－sensitive computer has its own “personality”5．What are emotion－sensitive computers believed to do in the future?A．They will take the place of teachers in teaching and learning.B．They can build a social relationship with human beings.C．They will replace human beings and control the world.D．They will have the same“personality”as their users.Ⅳ.翻译句子1．随着春天的到来，万物复苏了。

Unit 3 Computers课时作业i •阅读理解A（2019 •郑州模拟）As our cell phones get smarter , smaller and faster , and enable users to connect at high speeds to the Internet , an obvious question arises: is the mobile handset into the next computer? In one sense , it already has.Today's most complicated mobile phones have the process ing power of a mid —1990s PCwhile using 100 times less electricity.And more and more of today's mobile phones have computer —like features , allowing their owners to send e —mails , browse（浏览）the Web and even take photos? 84 million mobile phones with digital cameras were shipped last year.We ask the question whether mobile phones will ever overshadow or replace the PC, and the issue suddenly becomes questionable.PC supporters say mobile phones are too small and connect too slowly to the Internet to become effective at tasks now performed on the large scree ns and keyboards of today's computer.Fans of the mobile phones respond: just ing techniques will solve the limitation of the mobile phone. “One day, two or three billion people will have cell phones , and they are not going to have PCs ，” says one inven tor of the smart phone and the chief tech no logy officer of an importa nt smart phone company. “The mobile phone will become their digital life. ”The inven tor's a n ewest product , the shiny , slim pocket —size cell phone , has a tiny keyboard , a built —in digital camera and narrow openings for added memory.The smart phone market makes up only five percent of overall mobile phone sales today , but the figure has bee n doubli ng each year」n the Un ited States , it's the bus in ess crowd that's primarily buying these han dsets. “ What makes the smart phone so much better than the computer is that it's always with you, always up and always ready，” says one of them , who works in an 80 —memberlaw firm , which recently started giving its lawyers smart phones in stead of laptops.【文章大意】本文是一篇议论文，针对手机将来是否会取代电脑，不同的人群有不同的观点。

Unit 3 ComputersⅠ.阅读理解[2020·成都市高中毕业班摸底测试]Self－driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human－driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair.Crash statistics for human－driven cars are gathered from all sorts of driving situations, and on all types of roads. However, most of the data on self－driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle ahead. Automated cars are good at those tasks, but so are humans.It is true that self－driving cars don't get tired, angry, frustrated or drunk. But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive human driver. Nor do they possess the foresight to avoid potential perils. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.To a self－driving car, a bus full of people might appear quite similar to an uninhabited cornfield. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate (评估) a situation the same way a human would.And machines can't be programmed in advance to handle every imaginable set of events.Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation (航空) shows that as new automated systems are introduced, there is often an increase in the rate of disasters.Therefore comparisons between humans and automated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one－for－one exchange.1．What makes the comparison between self－driving cars and human－driven carsunfair?A．Self－driving cars never get tired.B．Statistics are collected differently.C．Machines can make decisions faster.D．Self－driving cars know the world better.2．What does the underlined word “perils” in Paragraph 3 most probably mean?A．Dangers. B．Self－driving cars.C．Pedestrians. D．Human－driven cars.3．In which aspect can self－driving cars beat human－driven cars?A．Driving steadily.B．Climbing steep slopes.C．Evaluating the cost of loss.D．Making complex decisions.4．Why does the author write this text?A．To support human－driven cars.B．To show his doubt about self－driving cars.C．To call for exact evaluation of self－driving cars.D．To stress the importance of reducing car accidents.Ⅱ.七选五[2020·贵州适应性考试] The small habits really damage the wallet.
