The home of the future won’t be completely different and we will be living in houses and flats just as we do today.But people will want to shape their homes to match their dreams.No two homes will be the same.People will be able to buy “house kits” containing a basic house structure,with movable walls,doors and windows.They will put together the different parts to create the homes they want.
Many jobs that we do today will disappear,others will still exist but will change and new jobs will be created.Skilled workers such as builders,gardeners and electricians won’t disappear because machines can’t replace them.Teachers will still exist because students need human contact.But they will be using modern technology in class more and students will be working more from home.The medical technology revolution and space travel will create new jobs which we can only imagine today.
Space holidays will develop in the future,but these holidays won’t be for everyone because they won’t be cheap.Short space trips will develop first,then space hotels will orbit Earth where it will be possible to have a longer vacation.By the end of the next century,there will be holiday centres on the moon with leisure facilities for families.
Paper won’t exist in the future.Instead,there will be e-paper which people will be able to use over and over again.This will develop in order to save natural resources.E-newspapers and e-magazines will replace traditional newspapers and magazines,enabling us to stay informed of the latest news.
The laws of physics tell us that Earth is going to disappear sometime in the future.This isn’t going to happen tomorrow but scientists predict that it will happen in five billion years when our sun explodes (爆炸).We will have to explore the universe and find another home.At some point in the distant future,either we stay on Earth and die with it,or we leave and move to another planet.There won’t be any other choice.
(　　)1.What will homes of the future be like
A.They will be movable as you want.
B.They will be different from one another.
C.They will be very similar to our homes.
D.They will be completely different from those of today.
(　　)2.What does Paragraph 2 imply
A.The future will witness job changes.
B.Skilled workers will face great changes.
C.Technology will totally replace workforce.
D.An unimaginable life will come into being.
(　　)3.Why will e-paper replace traditional paper
A.Because young people like it.
B.Because it will be cheaper to produce.
C.Because it will be convenient to carry.
D.Because it won’t waste natural resources.
(　　)4.Why will we have to move to another planet in the distant future
A.Because Earth will explode.
B.Because we want to live a better life.
C.Because we want to save ourselves.
D.Because Earth is too crowded to live on.
语篇导读:本文是说明文。文章向我们介绍了未来的生活,包括我们未来的家、职业、太空旅行和可重复利用的电子纸等。
答案及剖析:
1.B　细节理解题。根据第一段中的“No two homes will be the same.”可知,没有两个家是一样的。由此可知,未来的家相互之间都是不同的。故选B。

Ⅲ.阅读理解(共4题;每题2.5分,共10分)
Imagine a world where technology helps doctors see diseases earlier,develop treatments faster,and care for patients more personally.That’s the promise of artificial intelligence,or AI,in healthcare.
AI’s first big role is in diagnosis.Think of it like a super-smart assistant for doctors.In skin cancer checks,AI algorithms (算法) can analyse skin images and spot melanoma—a dangerous skin cancer—with surprising accuracy.It can even notice tiny details that human eyes might miss.Similarly,when looking at X-rays or MRI (核磁共振成像) scans,AI can quickly highlight areas that need a doctor’s attention,helping catch illnesses like cancer or heart disease sooner.
Beyond diagnosis,AI speeds up drug development.By simulating molecular interactions,AI recognises potential drug candidates faster and cheaper than traditional methods.This breakthrough could lead to life-saving treatments for conditions like Alzheimer’s disease and cancer.
Wearable devices,like smartwatches,are getting smarter thanks to AI.They can track your heart rate,sleep,and even stress levels.If something unusual is detected,like an irregular heartbeat,the device can send a warning,which lets you and your doctor act fast.AI can also help create treatment plans tailored just for you by considering your health history,lifestyle,and even genetics.
While AI is powerful,it’s not perfect.It needs lots of data to learn,and if that data is biased—for example,mostly from one group of people—it might not work well for everyone.Furthermore,ethical dilemmas may arise.While AI improves decision-making,it cannot take the place of human empathy (同理心).Doctors can listen,empathise,and make complex decisions.Their intuition and patient communication remain irreplaceable.Striking a balance between AI efficiency and human touch is significant.
So AI isn’t here to replace doctors or nurses.Instead,it’s a tool to help them provide better,faster,and more personalised care.As AI technology advances,so will our ability to rise to health challenges and improve lives.The future of healthcare isn’t just about machines — it’s about how we use them to work better together.
(　　)1.What is a key advantage of AI in diagnosis
A.It reduces the cost of MRI scans.
B.It can replace radiologists completely.
C.It speeds up hospital check-in processes.
D.It detects illnesses missed by human doctors.
(　　)2.What can be inferred about AI’s impact on healthcare
A.AI-powered wearable devices can treat heart disease.
B.AI algorithms can only be used in skin cancer checks.
C.AI can speed up drug discovery,which might lead to breakthroughs.
D.AI will cause people’s needs for hospitals to disappear.
(　　)3.Why might AI fail to work equally well for all patients
A.Because it may learn from biased data.
B.Because it lacks human empathy.
C.Because it can’t replace the human touch.
D.Because it can’t improve human decisions.
(　　)4.What is the best title for this passage
A.The Promise of AI: Serving as a Powerful Tool
B.AI in Healthcare: Opportunities and Challenges
C.The Future of Healthcare: Replacing Doctors with AI
D.AI in Healthcare: Revolutionising Diagnosis and Treatments
语篇导读:本文是说明文。文章主要讲述了人工智能在医疗领域的应用、优势、挑战及前景。
答案及剖析:
1.D　细节理解题。根据第二段倒数第二句可知,人工智能在诊断方面的一个关键优势是它能检测出人类医生可能漏诊的疾病。故选D。
2.C　推理判断题。根据第三段内容可知,人工智能可以加速药物开发,这可能会带来医疗突破。故选C。
3.A　细节理解题。根据倒数第二段第二句可知,人工智能可能无法对所有患者都同样有效,因为它可能会从有倾向性的数据中获取信息。故选A。
4.B　标题归纳题。通读全文,尤其是第一段可知,本文主要讲述了人工智能在医疗领域的应用、优势、挑战及前景,因此B项最适合作为文章标题。故选B。
Ⅳ.语法填空(共10题;每题1.5分,共15分)
The future always 1.　　　　 (interest) people of all ages.With technology 2.　　 　　 (develop) so rapidly,we can now predict what life might be like in 50 years.Some predictions may sound like science fiction,3.　　　　 they are often based on real scientific research.
For example,smart homes will allow people 4.　　　　 (control) household devices through simple voice 5.　　 　　 (command).Advanced medical technology will help doctors treat diseases much 6.　　 　　 (early) than before.However,experts have warned that over-reliance on technology may 7.　　　　 (weak) human social skills.
Through the Internet,we can keep 8.　　　　 touch with friends around the world.We must remember 9.　　 　　 the future is not fixed — it is shaped by the decisions we make today.
10.　　　　 (use) technology wisely is essential for our future development.
语篇导读:本文是说明文。文章探讨了科技发展对未来生活的潜在影响,并强调了明智地运用科技的重要性。
答案及剖析:
1.interests　考查动词的时态和主谓一致。主语The future为第三人称单数,且本句陈述的是客观事实,时态应用一般现在时。故填interests。
2.developing　考查非谓语动词。此处为“with+宾语+宾语补足语”结构,technology与develop为主动关系,应用现在分词作宾语补足语。故填developing。
3.but　考查连词。空前句意“一些预测可能听起来像科幻小说”与空后句意“它们通常是基于真实的科学研究”之间构成转折关系。故填but。
4.to control　考查非谓语动词。allow sb to do sth为固定搭配,因此设空处应用动词不定式作宾语补足语。故填to control。
5.commands　考查名词复数。command作“命令”讲时为可数名词,其前无限定词修饰,因此应用复数形式。故填commands。
6.earlier　考查副词比较级。根据标志词than可知,此处应用比较级形式。故填earlier。
7.weaken　考查词形转换。根据空前的may可知,空处应为动词原形,weak的动词形式为weaken,意为“削弱”。故填weaken。
8.in　考查固定搭配。keep in touch with为固定短语,意为“与……保持联系”。故填in。
9.that　考查宾语从句。remember后接宾语从句,且从句成分和意思均完整。故填that。
10.Using　考查动名词。分析句子结构可知,此处需用动名词短语作主语,表示“明智地运用科技”这一概念;设空处位于句首,单词首字母应大写。故填Using。UNIT 2　课时作业(三)

Mr Watson is late again.He has no time for breakfast.But at least he has the basic necessities: bang on the minute,the coffee machine supplies his first hot drink.The motion sensor is activated and notifies the garage door,which now opens.In all the rush,he has forgotten to switch off the iron and light.No problem.He deals with that while underway via his smartphone.
What Mr Watson benefits from is the idea of “Smart Home”,an idea more topical and attractive than ever.But what does “Smart Home” mean “Smart Home” is an indicator of the use of technical systems,automated processes and connected,remote-controlled devices in apartments and houses.The main objective of the functions is to improve the quality of life and convenience in the home.Other goals are greater security and more efficient use of energy thanks to connected,remote-controllable devices.
“Smart Home” was brought to life through continuous technological progress,in particular through the Internet and computer.Science fiction literature in the 1950s described the first visions of homes that were monitored and controlled fully automatically by machines.An American film in 1999 was about household computers and the consequences when smart machines took on a life of their own.The Fraunhofer In-Haus Centre,which was opened in Duisburg in 2001,was a lighthouse project which involved exploring and testing new system solutions in a residential environment.The first T-Com House from Deutsche Telekom in Berlin was opened to interested visitors in 2005.The focus of this model project was on connecting various home appliances and controlling them by means of different input devices.
Scientists have already been working for decades of years on “Smart Home”.There are still challenges as a result of trends like an aging society,greater environmental awareness and the related wish for a sustainable energy supply.But there are more solutions.What is the next big evolutionary advance
(　　)1.How does the author introduce the topic in Paragraph 1
A.By giving a definition.
B.By describing a scene.
C.By making a prediction.

A.It is a newly-formed concept.
B.It involves energy-consuming devices.
C.It values security more than efficiency.
D.It’s not all about comfort and convenience.
(　　)3.What is the main idea of Paragraph 3
A.“Smart Home” has changed people’s lives a lot.
B.“Smart Home” is equipped with advanced devices.
C.“Smart Home” develops with technological advances.
D.“Smart Home” is favoured by more than one generation.
(　　)4.What is the author’s attitude to the future of “Smart Home”

Science and technology is truly reshaping our lives,and shopping is one area where their impact is quite visible.Many things that we thought would never happen are now a reality.
My grandmother once told me she usually covered a long distance to a small village shop to buy goods,as there were no better choices.Later,supermarkets opened in our town,so my mother used to shop there,enjoying the convenience of finding all items in one place.Now,online shopping has become a common phenomenon with the advancement of smart devices.
For the future,I believe shopping will be more high-tech.Virtual reality might let us “touch” and “try” products at home.Technology will make shopping smarter and more enjoyable.UNIT 2　课时作业(一)

The home of the future won’t be completely different and we will be living in houses and flats just as we do today.But people will want to shape their homes to match their dreams.No two homes will be the same.People will be able to buy “house kits” containing a basic house structure,with movable walls,doors and windows.They will put together the different parts to create the homes they want.
Many jobs that we do today will disappear,others will still exist but will change and new jobs will be created.Skilled workers such as builders,gardeners and electricians won’t disappear because machines can’t replace them.Teachers will still exist because students need human contact.But they will be using modern technology in class more and students will be working more from home.The medical technology revolution and space travel will create new jobs which we can only imagine today.
Space holidays will develop in the future,but these holidays won’t be for everyone because they won’t be cheap.Short space trips will develop first,then space hotels will orbit Earth where it will be possible to have a longer vacation.By the end of the next century,there will be holiday centres on the moon with leisure facilities for families.
Paper won’t exist in the future.Instead,there will be e-paper which people will be able to use over and over again.This will develop in order to save natural resources.E-newspapers and e-magazines will replace traditional newspapers and magazines,enabling us to stay informed of the latest news.
