1 . While the idea of living on the moon was once a thing of science fiction,several space agencies including NASA and Roscosmos are racing to make it a reality.Now,one scientist has revealed what he thinks the lunar cities could look like in the next 150 years,in a project named“Moontopia”.

Professor Lewis Dartnell,a science communication expert at the University of Westminster,has teamed up with Hillarys to bring his vision to light.He said:“As our understanding of space advances,the opportunity to start a new world becomes ever more possible.Moving home or to another country is already incredibly exciting,imagine what it would be like to move to an entirely different environment.The challenges and problems would be new and hard but the mind boggles at what the human race could achieve if we take this next step.”

Professor Dartnell predicts that homes in Moontopia will be built in lava tubes,and that settlers will travel around using bikes or on foot.Moontopia would also include an airlock that would keep the city pressurized,meaning people could walk around freely with spacesuits.The lunar city could have a lakes,parks and basketball courts.

While this sounds pretty great so far,if you’re used to eating what you want,when you want it,living in Moontopia could be a struggle.Other key challenges would include adapting to the temperatures on the Moon.In direct sunlight,the moon can reach up to 100℃,while at night,temperatures can drop to-170℃!Thankfully,the temperature inside lava tubes would be easily controlled.

While Professor Dartnell’s vision is merely based on predictions,lunar cities could become a reality in the not-so-distant future.In 2016,Russia announced plans to build a human settlement on the Moon by 2030,while NASA plans to establish a lunar outpost in 2028.

2 . My dad works with green technology. Last summer, he was sent to a small town called Gaviotas in Colombia. He decided to take me with him. At first I wasn’t too keen. What was I going to do in the middle of nowhere, in a country where I couldn’t even speak the language? And anyway, what was so special about Gaviotas?

My dad told me that Gaviotas was an example of how people could live without destroying the environment. This got me a bit more interested, so I did some research. I found out that Gaviotas was founded in 1971 by a group of scientists and artists. They had decided to build a completely new town in the remote, war-worn eastern Colombia where there was nothing.

When we eventually arrived, I was amazed by how green it was and my dad explained that they had replanted millions of trees. There were many different species of birds flying about and flowers everywhere. I was beginning to like it. My dad’s contact in Gaviotas has a son exactly my age Ricardo. He speaks really good English and so for the next week he was my guide to this amazing place. The first thing he pointed out to me was all the fantastic technology that had been invented there. Ricardo told me that they produce 70% of all their own energy and food with very little waste. The trees they planted more than compensate for any greenhouse gases they emit（排放）.

But Gaviotas is not a success just because of its green technology, it’s also a model for how people can live more peacefully together. Every family gets a free home, free meals and free schooling for the children. So there is no poverty. People get on well with each other. It’ s fantastic.

I was really sad to leave Gaviotas, but now I have a new dream: I hope that 20 years from now, we’ll all be living in towns like Gaviotas.

3 . I don’t believe Artificial Intelligence (AI) could replace my teaching career. I have always been interested in human connection, and the ways in which I can use these connections to inspire change and make a difference.     1    , there are other ways where AI could make a more efficient and effective difference than I could on my own.

My teaching experiences over the past several years have been creative and inspiring. I believe that the job of educators extends beyond simply teaching students a set curriculum.     2    , they must constantly reflect on ways to better their teaching, and they must inspire their students to be the best versions of themselves. And now with the help AI, they could achieve these goals much easier.

    3    . First, AI can be used to promote fundamental skills, such as mathematical education and vocabulary lessons. Additionally, I see AI being used for such necessary tasks as answering questions and grading assignments. Thus I could focus my attention to establishing human connection, individualizing lesson plans and inspiring my students.

    4    . I believe AI could provide a strong basis for educational equality around the world. According to Todd Leopold, close to 800 million people worldwide are functionally illiterate (不识字的). Due to its ability to efficiently pass knowledge across large groups of people fewer teachers may be needed in some schools.     5    .

A．Since students will always need a human teacher

B．The benefit AI brings is far beyond my own classroom

C．I think AI is a powerful assistant to my future classroom

D．The need for students to learn how to use AI will also grow

E．Although human connection may never be able to be fully replaced by AI

F．This could be an opportunity for students everywhere to receive equal education

G．They must observe and get to know their students in order to individualize educational plans

4 . In the future those who are taking care of old people may get help from the house itself.

Over the last few years, new technology, such as the Internet, Wi-Fi and flat TV screens, has changed our homes and the way that we live. Now, another technology revolution is happening. A new project at the University of Hertfordshire wants to create a home that monitors people living in it who are elderly.

The researchers have developed a wristband device（装置）which helps us to watch the elderly person who is wearing it. The device collects information to see if the person has fallen or has wandered away from where he or she should be.

The assisted-living project is part of the university’s wider Interhome project, which is the development of a smart house. The house remembers the habits of the person who lives there and it uses very low amounts of energy. The Interhome team hope that offering this service will help take care of the elderly. They say, “It’s very important that these technologies are there to help and support and not replace any of the existing services.”

The Interhome is not just a research method. It’s also a way for students from different scientific backgrounds to learn and develop technology. The university uses the latest technology to help students get experience by developing new hardware and software themselves. The team includes design, engineering and computer science students working together.

“We are working on a smart-home project in Watford with some companies at the moment,” says the project leader. “We are looking at how a smart home can provide even more services.” This could help millions of old people around the world have a better and safer life in the future.

5 . How do you pay for things in a shop? Perhaps you like the touchable reliability of hard cash? Maybe the financial flexibility of a credit card suits you better? Or perhaps you prefer the simple convenience of a smartphone?

Whatever you use today, experts believe all these methods could soon become outdated. Instead, we will use our bodies: our eyes, our fingerprints, even our mere presence in the store. In fact it's happening already. Amazon are trialing stores which have no checkouts, where   technology tracks the items you've taken from the shelves and deducts（扣除） the total from your   account when you leave the shop.

French supermarket Monoprix takes a different path: you choose your groceries and leave them with a human cashier. You then leave the shop while the cashier adds up your bill,   charges your account, and organizes delivery to your home.

Amir, CEO of Barclaycard predicts that such new developments mean the end of the plastic credit card. Instead, wearable items such as rings, necklaces and key chains will carry chips（芯片） that allow shoppers to shop, going between the web, an app or in store.

And while all the above payment methods are supported by accounts held in traditional currencies, let's not forget the rise of alternatives such as Litecoin. Virtual（虚拟） currencies can rise in value very quickly. One such possibility is explored in the movie In Time. It imagines a futuristic society in which the currency is time itself, where people trade the amount of time they have left to live.

Or perhaps we'd do better to wind back the clock to the simpler financial world of the equal exchange economy. While the term recalls images of bags of grain and herds of sheep being exchanged in ancient times, there are signs that are making a comeback in today's world of modern technology. Maybe the only thing we know for certain is that money will keep updating.
