It’s also a time when we’re usually more carefree and less constrained.

READING

Future humans. I can match visual information to a text.

THINK! How are you different from your parents and grandparents? Will people in the future be different? Why?

Answer:

Compared to previous generations, I have differences in appearance, lifestyle and mindset. For example, I was born and raised in a time when technology had a breakthrough, developed strongly, was exposed from an early age, so compared to my grandparents and parents, I was able to get acquainted with and use technology better.

Yes, I think people in the future will be different. Because humans have always evolved to adapt to changing living conditions and environments. In addition, today's life is more and more modern and changing, so people will also have certain changes in aspects such as appearance, physical strength and thinking.

1. Read the article on the future of human beings. Match paragraphs 1-5 with pictures A - E.

FACES OF THE FUTURE

Humans have adapted and changed through the ages and, unless a catastrophe destroys the Earth, we'll probably survive and continue to change. Scientists are already saying that children born now might live until they're 150. Further into the future, perhaps people won't die but simply buy new body parts as they get older!

What other changes are possible in the years ahead?

1. Homo Informaticus

If we continue to use computers and screens more and more, our eyes and brains will probably get bigger in order to process more information.

2. Neo-humans

If there’s a terrible war or an epidemic, survivors might leave the cities and live in caves. They'll become stronger, hairier and more agile.

3. Homo Perfectus

If scientists manipulate human genes, will some people pay to have children who are better looking, healthier and more intelligent than ‘normal’ humans?

4. Cyborgs

Soldiers of the future might be part human, part machine, with super-strong body parts, auto-zoom eyes and a brain connected by Wi-Fi to super computers.

5. Space humans

If the Earth gets too crowded, humans will move to other planets. If they adapt to a different atmosphere and gravity on another planet, they won't look the same as humans on Earth.

Answer:

WRITING

A blog post. I can link ideas to express purpose.

THINK! If our earth gets tô crowded, will we move to another planet?

Answer:

Yes, I believe that if our earth gets too crowded, we will move to another planet.

With the prospect that in the future there will be no land to live on, humanity will find a new home in space, most notably the idea of sending humans to Mars to live. I supposed that the colonization of many planets will ensure our existence thousands of years from now. Mars is an ideal planet for us because it's the right size, close to Earth, and has frozen water on its surface.

1. Read the blog. Do you want to live on another planet when the Earth is too crowded?

Dave23

Do you think we will move to somewhere else in this vast universe if our 'home' gets too crowded? Here is my thought about an ideal planet to live on.

I wonder what it would be like to set foot on an exotic ground. Humans will have to find ways to adapt to new environments. I suppose that we will be stronger and more flexible.

I guess there will be more chances to explore a new ecosystem, too. What kinds of animals and plants will we discover? Who knows! Will we be making friends and living with the native people?

Moreover, with our intelligence and new resources, I imagine that we will surely thrive. Humans are going to develop new technology and new vehicles, such as flying cars or teleporting portals to better our life.

Above are some of my views about ideal life on another planet. What do you think about them? Tell me in the comment section.

Answer:

Yes, I want to live on another planet when the Earth is too crowded. Because it can be a chance to help people become stronger and more flexible. There will be more opportunities to explore a new ecosystem with new resources. In addition, on another planet, humans are also going to develop new technology and new vehicles, such as flying cars or teleporting portals to better our life.

Answer:

My ideal planet for humans to live on would provide a suitable amount of energy and heat for life to thrive. I suppose that we will be taller, stronger and more intelligent in our new life. The planet would have a diverse range of landscapes, which has a comfortable climate that was not too extreme, with plenty of freshwater sources and a variety of plant and animal species to support a healthy ecosystem. I expect that the inhabitants will have a strong sense of community and a deep connection to the natural environment, with a shared commitment to preserving the planet for future generations. In terms of technology, humans will invent advanced infrastructure to support modern living, including reliable communication networks, efficient transportation systems, and sustainable sources of energy.
