1 . What is the future of AI (人工智能)? Will it be a good thing? We asked four students what they think.

In the future, we     1    (live) in smart homes that will keep us secure, save us energy, and provide a more comfortable environment. Smart homes will control just    2    everything in our home. They will use integrated     3    (sensor) to go into an energy-efficient mode all by itself when we leave home. In     4    (add), smart homes will be monitoring our health every day. If they find there is something    5    (normal) or you have a critical illness, they will give you a     6    (warn) early on and    7    (potential) save our life.Smart homes will also be able to prevent serious damage from accidents. If they find something wrong they will detect    8    and provide us with the relevant information for us    9    (fix) the problem. In a word, this smart technology is not a fantasy, and it will take some years    10    most new homes begin to use this new technology.

Have you ever imagined    1     (live) in 2120, 100 years from now? Latest research describes robots, underwater cities and holidays in space. City planners and experts on space and architecture    2     (ask) to give their opinions on life in 2120. According to them, the way people live, work and play will be totally different     3     how we do these things today. They also said that over twenty years ago, people couldn’t imagine how the Internet     4    the smartphone would change our lives. But today, both have changed the way we communicate, learn and do daily things, and the changes in the next century will probably be even     5    (great).

Those     6     (question) in the research said that people may not go to the office in the future but will work at home instead. People will have advanced 3D printers which will let     7    download a design for furniture or a food recipe and then “print” the sofa, table or pizza at home.     8     will also be less need for visits to the doctor. People will have a home health capsule that will “diagnose” what the problem is and provide    9    (treat). They will also be going into space for holidays, and     10    (hopeful), to get resources that have been used up on earth.

7 . Step into Moving to Mars, an exhibition of the Mars mission and colony design at London’s Design Museum, and immediately you have good reasons for not moving there.

Frightening glowing wall-texts announce that Mars wasn’t made for you, that there is no life and little precious water, that, dressed in a spacesuit, you will never touch, taste or smell the planet you now call “home”. As Lisa Grossman wrote for New Scientist a couple of years ago, “What’s different about Mars is that there is nothing to do there except try not to die.”

It is an odd beginning for such a celebratory exhibition, but it provides a valuable, dark background against which the rest of the show can sparkle(闪耀)—a show that is, as its chief manager Justin remarks, “not about Mars; this is an exhibition about people.”

Moving along, there is a quick yet clear flash through what the science-fiction writer Robinson calls “the history of Mars in the human mind”. A Babylonian clay tablet and a Greek vase speak to early ideas about the planet. A poster for the original Total Recall film reminds us of Mars’ psychological threat.

The main part of the show is our current plans for the Red Planet. There are real spacesuits and models of 3D-printed Martian settlements and suitable clothing and furniture. Mission architectures and engineering sketches line the walls. Real hammers meant for the International Space Station are wall-mounted beside a low-gravity table that has yet to leave, and may indeed never leave, Earth.

This, of course, is the great strength of approaching science through design: reality and assumptions can be given equal visual weight, drawing us into an informed conversation about what it is that we actually want from a future on Mars.

8 . 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 sanguine about our future. We should be happy and believe good things will happen.

I have loved     1     (watch) films since I was a child.     2     (go) to the local cinema with my parents was a pleasant memory. The cinema was old and uncomfortable, but I liked it and always looked forward to     3     (see) a new movie. Now they’ve stopped     4     (show) films there. The owner would like to go on     5     (run) the cinema, but the cinema is so old that it needs     6     (repair), which means     7     (spend) a lot of money.

The last film shown in this cinema was a detective film. It was five minutes from the end when suddenly all the lights went out and the film stopped.     8     (wait) in the darkness made us kind of anxious. Then the owner appeared with a torch. “I regret to tell you,” he said. “The electricity has failed. We’ve tried     9     (phone) the electricity company, but they said they couldn’t help.” Then he explained to the audience how the film ended.

What a funny and disappointing experience! But I don’t regret     10     (have) the chance to witness the last film in this cinema.
