1 . Who has no regrets about things done in the past? Wouldn’t it be nice if, somehow, we could go back to change a couple of bad decisions? This sounds like science fiction.
The laws of physics prohibit traveling back in time for many reasons. If we did travel back in time and changed the course of events, we would be altering the course of history. An example often cited is the grandfather’s paradox (悖论): If your grandfather died when he was still a high school student, he wouldn’t have met your grandmother and your father and you wouldn’t exist.
Putting humans or consciousness traveling back in time aside for the moment, is there anything in science even similar? Surprisingly, yes. At the level of quantum particles (量子粒子), there is something called Wheeler’s delayed-choice experiments that show that actions in the present can influence the past. The experiments use something called the wave-particle duality (波粒二象性) of light and of matter. The fact that the physical nature of quantum objects is undetermined until it is measured. In other words, this means that a particle of light or of matter can behave either as a wave (spreading out in space) or as a particle (staying together) depending on the measuring devices. Long and ongoing discussions about the nature of quantum physics are still trying to work out what this actually means. Do our minds determine the nature of physical reality?
Should we offer food for thought for the future or the past? Unfortunately, these experiments say very little about how we could interfere with the past in events relevant to the human scale. Better to think carefully about decisions than to try to fix them backwards.

4 . When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr. Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn’t take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.
Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note — “Please add a bottle of buttermilk next delivery” — and place it in the box along with the empty bottles. And then, the buttermilk would magically (魔术般) appear.
All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn’t freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.
There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk, thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practical to have a delivery service.
Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch (门廊) . Every so often my son’s friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.
1. Mr. Basille gave the boy a quarter out of his coin changer to __________.A.show his magical power | B.pay for the delivery |
C.satisfy his curiosity | D.please his mother |
A.He wanted to have tea there. | B.He was a respectable person. |
C.He was treated as a family member. | D.He was fully trusted by the family. |
A.Nobody wants to be a milkman now. | B.It has been driven out of the market. |
C.Its service is getting poor. | D.It is not allowed by law. |
A.He missed the good old days. | B.He wanted to tell interesting stories. |
C.He needed it for his milk bottles. | D.He planted flowers in it. |

8 . Technologically, the 20-year jump from 2015 to 2035 will be huge. Back in 1995 we were in the early days of the Internet, we worked in small rooms and our computers were heavy and powered by Windows 95. There were no touch screen phones or flat screen TVs; people laughed at the idea of reading electronic books.
So, what will our world really be like in 2035? What will the future jobs and technology be like? The world in 2035 will probably be much like it is today, but smarter and more automatic. We can see the future of our work first.
Taxi drivers will be replaced by self-driving Uber cars and receptionists will be replaced by robots. Doctors can use vast medical databases and travel agents will be wiped out by trip-planning, flight-booking web services. Even writers are threatened by companies such as Narrative Science, which currently uses AI to create sports reports and financial updates.
Obviously, there will also be new jobs created: the computer engineer who fixes the self-driving Uber taxis, programmers, space tour guides and vertical (垂直的) farmers. Technology will continue to disrupt (扰乱) businesses and get rid of jobs, creating new professions we can’t yet envisage now.
Those of us who work probably won’t do so in a traditional office either. We’re already seeing a shift in the definition of work. It’s now a task you perform, not a place you go to. Productivity is no longer measured by sitting at a desk. There’s no nine to five. No job for life.
The biggest advantage of working from home is that you save a lot of time commuting back and forth to work. You can spend extra time with your children or spouse and read the newspaper instead of sitting in traffic. Of course, advanced technology will ensure that most of us can work from home.
1. What’s the function of the questions in paragraph 2?A.Leading in the topic of the article. | B.Raising the thinking of the readers. |
C.Introducing the work of the future. | D.Inspiring readers to explore the future. |
A.Assess. | B.Ignore. | C.Imagine. | D.Reject. |
A.In the office. | B.At the hotel. | C.In the open air. | D.At home. |
A.The future health. | B.The future technology. | C.The future marriage. | D.The future transportation. |
9 . Is there anybody out there? For centuries humans have wondered although the ways in which we have gone about this have varied. As we have gained a greater understanding of the universe, our searches have taken on more concrete(具体的) forms. Questions about aliens(外星人) have become a subject for science rather than science fiction.
Now new cooperation between the Very Large Array (VLA) observatory in New Mexico and the SETI Institute in California means that our curiosity about whether aliens exist can be closer than ever before to being satisfied. Data from the VLA’S 28 radio telescopes, used to scan a vast area of sky, will be fed through a special supercomputer that will search for distant signals.
How likely it is that a signal will be found, and what this might mean, are hard questions to answer. SETI’s existing projects have not discovered any signals from other planets so far. But recent discoveries in space and Earth sciences have provided some encouragement for those who are enthusiastic about the possibility, however remote, of detecting other civilizations.
Once it was thought that our solar system could be unique. Since the discovery of the first exoplanet (a planet beyond the solar system) in the 1990s, thousands more have been located. Around one in five stars is now thought to have a planet in their orbit(运行轨道) in a so-called “habitable(适合居住的) zone”—that is, at a distance from the star where the temperature means that life is theoretically possible.
Are Earth’s 7.5 billion humans, along with billions of other animals and plants they share their home with, on their own in the universe? If there is another life form somewhere, could it be as intelligent as humans? Or could it threaten them? I think all of these need further exploration. As explorations of Mars continue, and a new set of observations from the James Webb Space Telescope are set to begin, our interest in the possibility of alien life appears as much as before.

B.New technologies are employed to find aliens |
C.Some exoplanets may have habitable zones |
D.Signals have been discovered from other planets |
A.Uncertain | B.Positive | C.Unacceptable | D.Worried |
A.Space: the unknown place | B.Finding aliens: possible or not? |
C.Receiving signals: aliens appear again? | D.Exoplanets: home of aliens |
10 . Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and younglooking. In 2035, medical technology is better than ever. Many people at your age could live to 150, so at 40, you're not old at all. And your parents just had an antiaging (抗衰老的) treatment. Now, all three of you look the same age!
You say to your shirt, "Turn red." It changes from blue to red. In 2035, "smart clothes" contain particles (粒子) much smaller than the cells in your body. The particles can be programmed (编程) to change your clothes' color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, "You shouldn't drink that!" Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.
It's time to go to work. In 2035, cars drive themselves. Just tell your "smart car" where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology" is all around you.
So will all these things come true? "For new technology to succeed," says scientist Andrew Zolli, "It has to be so much better that it replaces what we have already." The Internet is one example—what will be the next?
