A
In 1900, an American engineer called John Elfreth Watkins made a number of predictions about what the world would be like in 2000.So what did Watkins get right and wrong 100 years later
Digital Color photography
“Photographs will be telegraphed from any distance.If there is a battle in China a hundred years hence, snapshots of its most striking events will be published in the newspapers an hour later... Photographs will reproduce all of nature's colors.”
Watkins did not, of course, use the word “digital” or describe precisely how digital cameras and computers would work, but he accurately predicted how people would come to use new photographic technology.When Watkins was making his predictions, it took a week for a picture of something happening in China to make its way into Western papers.
Mobile phones
“Wireless telephone and telegraph circuits will span the world.A husband in the middle of the Atlantic will be able to converse with his wife sitting in her boudoir in Chicago. We will be able to telephone to China as readily as we now talk from New York to Brooklyn.”
International phone calls were unheard of in Watkins' day.It was another 15 years before the first call was made, by Alexander Bell, even from one coast of the US to the other.The idea of wireless telephone was truly revolutionary.
Pre prepared meals
“Ready cooked meal will be bought from establishments similar to our bakeries of today.”
The popularity of ready meals in supermarkets and takeaway shops suggests that Watkins was right although he supposed that the meals would be delivered on plates which would be returned to the cooking establishments to be washed.
Hothouse vegetables
“Winter will be turned into summer and night into day by the farmer with electric wires under the soil and large gardens under glass.”
Large gardens under glass were already a reality, but he was correct to predict the use of electricity.Although colored lights and electric currents did not take off, they were probably experimented with.
语篇解读：1900年，美国工程师John Elfreth Watkins对人类100年后将会出现的事物做出了预测，他的许多预测如今已经实现。
1．The writer wrote the above paragraphs mainly to ________.
A．tell us what the world was like 100 years ago
B．explain how Watkins made so many predictions
C．introduce what Watkins predicted right
D．encourage us to make more predictions
解析：选C 写作意图题。一百年前，美国工程师Watkins做出了许多预言，本文主要介绍了得到应验的部分预言。
2．According to the second prediction, we can surely say 100 years ago ________.
A．people had easy access to international telephone calls
B．people could conveniently make a call from New York to Brooklyn
C．international phone calls were only available in large cities like Chicago
D．the first call from the east coast of the US to the west coast had been made
解析：选B 细节理解题。根据第二项预测部分“We will be able to telephone to China as readily as we now talk from New York to Brooklyn.”可知，当时人们已经可以方便地从纽约打电话到布鲁克林区。
3．What can we infer from the passage
A．Ready cooked meals were popular 100 years ago.
B．Watkins predicted plates would be washed before they were returned.
C．Watkins would carry out experiments to test his predictions.
D．Large gardens under glass were put in use 100 years ago.
解析：选D 细节理解题。根据最后一段“Large gardens under glass were already a reality”可知D项正确。
4．What will most probably be discussed in the next part of the passage
A．Some wrong predictions from Watkins.
B．Some predictions for the next century.
C．Great changes that took place in the 20th century.
D．Comments on Watkins' predictions from all walks of life.
解析：选A 推理判断题。文章第一段“So what did Watkins get right and wrong 100 years later？”提供了文章的写作线索，文中介绍了正确的预测，因此文章接下来会介绍Watkins的错误预测。
B
Many leading AI researchers think that in a matter of decades, artificial intelligence will be able to do not merely some of our jobs, but all of our jobs, forever transforming life on Earth.
The reason why many reject this as science fiction is that we've traditionally thought of intelligence as something mysterious that can only exist in biological organisms, especially humans.But such an idea is unscientific.
From my point of view as a physicist and AI researcher，intelligence is simply a certain kind of information processing performed by elementary particles (基本粒子) moving around，and there is no law of physics that says one can't build machines more intelligent than us in all ways.This suggests that we've only seen the tip of the intelligence iceberg and that there is an amazing potential to unlock the full intelligence that is potential in nature and use it to help humanity.
If we get it right, the upside is huge. Since everything we love about civilization is the product of intelligence, amplifying (扩大) our own intelligence with AI has the potential to solve tomorrow's toughest problems. For example, why risk our loved ones dying in traffic accidents that self driving cars could prevent or dying of cancers that AI might help us find cures for Why not increase productivity through automation and use AI to accelerate our research and development of affordable sustainable (可持续的) energy
I'm optimistic that we can develop rapidly with advanced AI as long as we win the race between the growing power of our technology and the knowledge with which we manage it.But this requires giving up our outdated concept of learning from mistakes.That helped us win the race with less powerful technology: We messed up with fire and then invented fire extinguishers (灭火器), and we messed up with cars and then invented seat belts.However, it's an awful idea for more powerful technologies, such as nuclear weapons or superintelligent AI — where even a single mistake is unacceptable and we need to get things right the first time.
语篇解读：本文是一篇议论文。文章主要论述了正确认识并恰当利用人工智能以使其造福人类的问题。
5．How do many people feel about leading AI researchers' predictions
A．Worried. B．Curious.
C．Doubtful. D．Disappointed.
解析：选C 推理判断题。根据第二段中的“many reject this as science fiction”可以推知，很多人不相信AI研究者的预言，认为那更像是科幻小说。
6．What does the author think of intelligence
A．We know little about it.
B．It belongs to human beings.
C．It is too difficult to understand.
D．We have a good command of it.
解析：选A 细节理解题。根据第三段中的“we've only seen the tip of the intelligence iceberg”可知，作者认为，人类对智能的认识还只是冰山一角。
7．What does the underlined word “upside” in Paragraph 4 probably mean
A．Cost. B．Potential.
C．Quantity. D．Advantage.
解析：选D 词义猜测题。第四段主要论述了恰当利用人工智能的好处，第一句是本段的主题句。upside意为“好的一面，优势”，相当于advantage。
8．What's important for us in the race between people and technology
A．Learning from failure.
B．Increasing our intelligence.
C．Avoiding making mistakes.
D．Making accurate predictions.
解析：选C 细节理解题。根据最后一段中的“we can develop rapidly with advanced AI ...giving up our outdated concept of learning from mistakes”可知，作者认为，赢得这场比赛的关键在于抛弃“从错误中学习”的过时理念。
Ⅴ.阅读七选五
You put a great deal of effort into reaching the college of your dreams. It's time to get started. But what's next The beginning of college life can be an exciting but awkward time. Follow these tips to adjust to your new life rapidly and make the most of your college experience.
·To save time and money, use the college's bus system. Taking the bus to school is quick, easy and free in most college towns. __1__ It's also a good way to be environmentally aware.
·__2__ You might not even need all of the recommended books. New textbooks cost a lot. Try buying used textbooks — it's a good way to save money and serve the purpose as well.

Ⅴ.阅读理解
A
We don't know how different our future will be in the future. We can only try to imagine it.
At first we think about human relationship. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet — even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won't be as important as they are today — we will feel a little lonely.
Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.
Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar powered cars, which will be much more environmentally friendly.
We could expect that the faster technological progress would lead to a more polluted environment. But it isn't true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.
Although we can't predict the exact changes which will be made in the world, we often think about them. We worry about our and our children's future; we have expectations, hopes as well as fears. But I think we should be rather optimistic about our future. We should be happy and believe good things will happen.
1．Why will people probably feel a little lonely in 2050
A．Because the number of people will become much smaller.
B．Because there will be less face to face communication.
C．Because people won't like making friends with each other.
D．Because people won't communicate with each other much often.
解析：选B 细节理解题。根据第二段的内容可知，在2050年，人们主要通过电脑进行交流，很少进行面对面的交流，人与人之间的关系也就淡薄了，因此那时的人们会感到有点孤独。
2．The third paragraph mainly tells us ________.
A．that computers will do all the things for human beings
B．how people will use computers to communicate with each other
C．that machines like computers and robots will help people a lot
D．how people will use robots to do the housework
解析：选C 段落大意题。根据第三段的内容可知，计算机和机器人等机器会给人类带来很大的帮助，故选C。
3．According to the passage, which of the following will happen in 2050
A．The relationship between people will be more important than that of today.
B．The way of spending holidays will be the same as that of today.
C．It won't be difficult for people to travel to other planets.
D．Our environment will be much more polluted with a growing number of cars.
解析：选C 细节理解题。根据第四段的“Traveling to other planets or to the moon will be available for everyone.”可知C项正确。
4．What does the passage mainly talk about
A．How people will communicate in the year 2050.
B．What our life will be like in the year 2050.
C．How people will travel and spend their holidays in the year 2050.
D．What high technology will appear in the year 2050.
解析：选B 主旨大意题。文章的第一段就是本文的中心，即设想2050年的生活会是什么样子的，故选B项。

What's more exciting than having a fresh hot pizza delivered to your door How about having it brought to you by a robot Thanks to Domino's Robotic Unit or DRU, that just became a reality. On March 8, the three foot tall robot made its first delivery to some lucky residents in Brisbane, Australia.
The autonomous DRU is the result of a cooperation between Domino's Pizza Australia and Marathon Robotics. The machine can cover a distance of up to 12 miles and back before requiring a battery recharge. Equipped with Google Maps and GPS guidance, DRU can go along bike paths and sidewalks and also find the most efficient way to its destination. LIDAR, a laser based sensor technology similar to the one used in self driving cars, enables DRU to detect and avoid obstacles, while traditional sensors ensure its path to its destination is safe. DRU's plastic shell protects the food from the bad weather, while its aluminum and steel container ensures that the pies remain hot.
The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders. To access their food, customers have to enter the unique code provided to them by the company. This not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.
Domino's expects additional DRUs to be ready for service in their various Queensland locations within the next six months. But don't expect these super cute robots to replace humans anytime soon. According to Domino's, the DRU still needs extensive testing, which the company believes could take up to two years. There is also the issue of regulations. The public use of autonomous vehicles is still banned in most countries. But Don Meij, the CEO of Domino's Pizza, is not worried. He believes that one day DRU will become a necessary part of the Domino's family.
语篇解读：文章介绍了一款名为DRU的机器人系统的工作原理以及它的功能：为人们派送比萨。
5．What's the function of LIDAR
A．Keeping DRU free of obstacles.
B．Recharging DRU's battery.
C．Helping DRU find its destination.
D．Protecting DRU from bad weather.
解析：选A 细节理解题。根据第二段中的“LIDAR ... enables DRU to detect and avoid obstacles”可知，LIDAR这种基于激光传感器的技术能让机器人侦测和躲避障碍物。故选A项。
6．What does the underlined word “accommodate” in Paragraph 3 probably mean
A．Heat. B．Hold.
C．Sell. D．Show.
解析：选B 词义猜测题。根据第三段第一句话可知，该机器人最多能装十个比萨。根据画线词前“and even has a separate cold area”可知，该机器人还有冷藏区域，因此可以推断冷藏区可以容纳饮品。故选B项。
7．Why does the company provide codes for its customers
A．To fit up more pizzas.
B．To prevent the pizza being taken by mistake.
C．To keep the pizza warm.
D．To get the pizza paid in time.
解析：选B 细节理解题。根据第三段最后一句“This not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.”可知，公司让顾客输入密码不仅能保证他们拿对自己的比萨，而且还能防止比萨被偷走。故选B项。
8．What can we infer about the future of DRU
A．It may need some improvements.
B．It will replace humans soon.
C．It may be banned in Australia.
D．It will soon be applied worldwide.
解析：选A 推理判断题。根据第四段中的“the DRU still needs extensive testing”该机器人仍然需要大量的测试可推知，该机器人需要改进，故选A项。PAGE

Warming Up & Reading — Pre-reading

A
What will people die of 100 years from now If you think that is a simple question, you have not been paying attention to the revolution that is taking place in biotechnology (生物科技). With_the_help_of_new_medicine,_the_human_body_will_last_a_very_long_time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of attention these days. But the change in medicine can be the real technological event of our times. How long can humans live Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells and so on, in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.
语篇解读：在未来的100年，人类的生命由于生物科技的发展可以无限期延长的愿望有可能成为现实。
1．According to the passage, human death is now mainly caused by ________.
A．diseases and aging B．accidents and war

3．How long can humans live in the future according to the passage
A．Over 100 years. B．More than 120 years.
C．About 150 years. D．The passage doesn't tell us.

B
Some people are pessimistic (悲观的) when they think about the future. They say that, a hundred years from now, we will have used most of the earth's resources. We will have polluted our seas badly, and be unable to eat fish from them. We will have made the air so dirty
that we will need to wear masks. The world's population will have doubled, and we will have used all the countryside for housing; there will be no farmland left.
Other people believe that man adapts very easily. They have a different idea of the future. How, in their views, will people be living in a hundred years' time
One architect (建筑师) believes that man will move off the land. He suggests that the city of the future will be a huge, pyramid shaped (金字塔形的) building, which will be floating on the surface of the sea. About 5,000 families will be living there, and the building will contain shops and schools as well as homes. By living on the sea, we will give farmers more land to grow crops.
As for oil, people will no longer need it: we will be heating our homes with power from the sun. And we will not be short of minerals, because there are plenty under our oceans. At the moment, we do not have the technology to get them out. But, in a hundred years' time, the optimists say, the new sea cities will be using these resources.
What will be in the shops in the year 3000 What will people be wearing How will people be traveling
Scientists who make predictions about the future suggest that, by the year 3000, shops will no longer puters will have replaced them; and people will order goods from home.
People will be wearing very light, thin clothes. By this time, scientists will have invented a fabric (织物) that keeps us cool in hot weather and warm in cold weather.
As for travel, the experts say that most people will be using public transport. Electric cars will be traveling through the streets day and night. Anybody will be able to stop one and use it.
An interesting picture. Unfortunately, we will not be there to see if these predictions come true.

A．electric cars will be going along the streets continuously
B．the resources under the oceans will never be used up
C．people will order goods from home
D．people won't suffer from cold any longer
解析：选B 细节理解题。文章最后四段是科学家的推测。倒数第二段第二句提到日夜运作的电车；倒数第四段末句提到人们将在家中订购物品；倒数第三段末句提到新发明的织物会使我们觉得冬暖夏凉；只有B项文中未提及。
C
What shape the school of the future will take is uncertain, but most educators and observers agree that the future school will go electronic.
In the future schools as we know will no longer exist. In their place will be community style centers operating seven days a week, 24 hours a day. Computers will become an essential part for an effective school of the future. Students will see and hear teachers on computers. Accessing “classrooms” on their home computers, students will learn at times most convenient for them. Yet some attendance at an actual school will be required to help students develop appropriate social skills.
One of American public schools, A．C.T. Academy in McKinney, Texas, was created as an actual “school of the future”. Originally funded by a D|S5.5 million grant from the US Department of Education, the school is now supported by the McKinney Independent School District.
At the school, knowledge is “actively constructed by the learner on a base of prior knowledge, attitudes, and values”. Sophisticated (尖端的) technology is in place to support the pursuit of knowledge.
The 250 Academy students all have access to a computer. The 12 to 18 year olds each have their own computer; 7 to 11 year olds have one portable computer for every two students; and 5 and 6 year olds use computers at fixed stations. In addition, the students use multimedia computers, Printers, CDROMs, laserdiscs, VCRs, video editing machines, camcorders, cable television, online services, and telephones — simple but effective research tools.
Whatever the shape of a school of the future might be, technology is always a huge part of it. The school days when computers mean word processing or playing games will be behind us.
7.According to the passage, what will play an important role in the school of the future
A．Computers. B．Environment.
C．Teachers. D．Skills.
解析：选A 细节理解题。根据第二段第三句可知，电脑在未来的学校中会起到很重要的作用。
8．It can be inferred from the passage that ________.
A．there will be no longer schools in the future
B．students will only stay at home to study in the future
C．many educators are sure of the function of future schools
D．many students are playing games on computers now
解析：选D 推理判断题。根据最后一段最后一句可知，在未来的校园生活中，电脑不再只是被用来处理文字或玩游戏了。由此可推知，现在很多学生用电脑来玩游戏。
9．From Paragraph 5 we know that those sharing a portable computer with another one are ________.
A．from any age group
B．12 to 18 year olds
C．7 to 11 year olds
D．5 and 6 year olds
解析：选C 细节理解题。根据第五段第二句中的“7 to 11 year olds have one portable computer for every two students”可知，七到十一岁的学生两人共享一台手提电脑。
10．Which of the following about A．C.T. Academy is TRUE
A．It is the only actual public school in the future.
B．It was funded by the McKinney Independent School District.
C．All students in it have a computer of their own.
D．High technology is made full use of in it.
解析：选D 正误判断题。根据文章第三段和第四段可知，A.C.T. Academy是按照未来学校模型设计的，学校利用了尖端技术来支持学生对知识的追求，因此D项正确。
