1 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?

2 . 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.

3 . The future home is something that people have talked about for decades. Because the future home idea inspires our imagination, scientists and engineers have been working hard to develop different systems to make houses “smarter”.
The video camera at the entrance recognize visitors using facial recognition. The facial recognition software of the future home will not only recognize friends, but strangers as well. And the software in the future home will run the strangers faces against a database of criminals.
The future home will also have smart application appliances (家电) as well. There will be a vast networking system connecting them. Ovens, microwaves and refrigerators will be controlled automatically, so remote cooking will be a possibility and meals are prepared for your arrival.
There will also be a green systems in place such as saving and reusing washing water and bathwater. Plants and people may receive pure or mineralized (含矿的) drinking water.
If you think this future home idea is pie in the sky or science fiction, then think again. Most of the systems described here are either in development or already out in the market. Future homes may not be standard yet for the middle class but this is not as far ahead as many people would think.

5 . Life on Mars: Is it really possible?
Now that Curiosity is beaming back Earth-like pictures of Martian landscape, the old question raises its head: Could man and woman ever go there? The answer is very definitely yes. There are a number of practical challenges to overcome first, however. There are differences between Earth and Mars, but also a number of similarities.
Phobos and Deimos
Unlike Earth, Mars does not have a polar magnetic field. Scientists believe that the two Martian moons, Phobos and Deimos, are little planets.
For the annual IGEM or International Genetically Engineered Machines competition, students around the world attempt to make living cells perform new tasks. In preparation for the human colonization of Mars, seeds and organic matter would have to be transported from Earth to begin growing plants and establishing a food supply.
Super-sized Bees
Plants need pollinators as well as water, and the best pollinator on Earth is the humble bee-and entire hives would be transported to Mars.
Overcoming Challenges-Opening Possibilities
There will be other challenges to overcome, for example, the effect on the human body of living in a field with low gravity.
| A．IGEM |
| B．The next question is: Could man colonize Mars? |
| C．Once there, the insects would be let loose among the plants. |
| D．However, all kinds of other interesting things will be happening. |
| E．But these are already issues for astronauts living on the International Space Station. |
| F．They do not have the stabilizing effect on the spin of the planet like the moon has upon Earth. |
| G．Mars has Earth-like seasons and the planet surface is abundant in minerals essential for plant growth. |
6 . If you could travel in time, where would you go? Perhaps you would watch an original performance of a Shakespeare’s play in Elizabethan England? What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you’d voyage far ahead of the present day to see what the future holds.
The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is the science fiction novel The Time Machine, which was written by H. G. Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term “time machine”, coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.
But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called “wormholes”, which could be used as shortcuts to other periods. Einstein’s theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking said you could travel into the future with a really fast spaceship—going at nearly the speed of light. Though building such a spaceship would of course be no simple task.
Even if you could travel into the past, there is something called the “grandfather paradox”. It asks what would happen if a time traveller were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveller wasn’t born, how would he travel back in time?
And would you really like to visit the future? In H. G. Wells’ book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles (触角). If that’s what’s in store, maybe we are better just living in the present day after all.

| A．the traveller is prevented from meeting his grandfather |
| B．the traveller goes back in time to seek for his grandfather |
| C．the grandfather’s death makes the traveller’s birth impossible |

9 . You’ve heard the predictions from some of the brightest minds about AI’s influence. Tesla and SpaceX’s chief Elon Musk worries that AI is far more dangerous than nuclear weapons. The late scientist Stephen Hawking warned that AI could serve as the “worst event in the history of our civilization” unless humanity is prepared for its possible risks.
But many experts, even those who are aware of such risks, have a more positive attitude, especially in health-care and possibly in education. That is one of the results from a new AI study released Monday by the Pew Research Centre.
Pew canvassed the opinions of 979 experts over the summer, a group that included famous technologists, developers, innovators, business and policy leaders. The interviewed experts, some of whom chose to remain anonymous, were asked to join in the discussion of a serious and important question: “By 2030, do you think it is most likely that advancing AI and related technology systems will improve human capacities and control them?”
Nearly two-thirds of experts predicted most of us will be mostly better off. But a third thought otherwise, and a majority of the experts expressed at least some concerns over the long-term impact of AI on the “essential elements of being human”. Among those concerns were data abuse, loss of jobs and loss of control brought by autonomous weapons and cybercrime. Above all, by taking data in and spitting answers out, those “black box” tools make decisions in digital systems. It is an erosion in our ability to think for ourselves.
1. Why is Stephen Hawking mentioned in the first paragraph?| A．To warn humans to give up AI as soon as possible. |
| B．To remind readers that a new AI age has come into view. |
| C．To prove great scientists care much about the future of AI. |
| D．To introduce the main idea of the text that AI benefits the future. |
| A．Most experts are certain that AI will be out of control. |
| B．Pew asked experts from different fields for opinions. |
| C．Pew concludes that humans will suffer from AI. |
| D．33% of experts think AI will have little impact on humans. |
| A．Because they make decisions in digital systems. |
| B．Because they can take data in and spit answers out. |
| C．Because they may weaken our ability to think independently. |
| D．Because they may decrease humans’ welfare in the long term. |
| A．Experts’ concern about AI. | B．Humans’ being controlled by AI. |
| C．Experts’ Expectation of AI. | D．AI’s influence on society. |
10 . Fancy a holiday to the moon? Sounds crazy? Not really. A Japanese company has been working on how to organize holidays to the moon for several years now.
Trying to make the holiday possible will not be an easy task, and the Japanese company plans to make it in stages.
The next stage is to build a big hotel orbiting 500 km above the earth. The hotel will orbit the earth once every four or five hours, which will offer visitors some fascinating views of the earth.
The final stage in the plan is the construction of a hotel on the surface of the moon itself. As solar energy would be used to provide power, it would be important to build the hotel near one of the poles of the moon in order to gather as much solar energy as possible.
So perhaps in a few years you might be enjoying yourselves on the moon.
| A．Next, the hotel will have a wide range of sporting activities. |
| B．Tourists who want to travel into space can stay at a big hotel. |
| C．The first thing to do is to organize trips around the earth for a few hours. |
| D．There would probably be holidays to a moon hotel within the next ten years. |
| E．There is plenty of sand, but the big problem will come with producing water. |
| F．This part of the development plan does not seem to be too difficult to carry out. |
| G．This is because a lunar day, which is 14 earth days long, is followed by 14 days of darkness. |
