1 . By 2050 we’ll be able to send memories, emotions and feelings across the Internet.
I’m talking about telepathy (心灵感应), really. We’ll still communicate the traditional way.
Medicine will develop fast, too. We will have cured certain forms of cancer, and we will have begun to treat the disease like the common cold. We’ll live with it. It will no longer be deadly.
| A．We will do a few tests. |
| B．People will live an easy life. |
| C．We won’t fear it like we used to. |
| D．Brain science will have changed communication. |
| E．We can already use human cells to grow skin, noses, ears, etc. |
| F．But communicating telepathically will avoid misunderstandings between people. |
| G．Our clothes will discover the beginnings of a heart disease, and advise us to get treatment. |
2 . “We are running out of space and the only places to go to are other worlds... Spreading out may be the only thing that saves us from ourselves. I’m convinced that humans need to leave the earth.” These are the words of the famous scientist Stephen Hawking, spoken at a science festival in Norway in 2017, a year before his death.
Hawking was not alone in this view. Many experts feel that the only way for humanity to last far into the future is to colonise (移民于) other planets. That way, if a terrible disease, nuclear war or some other disasters strike the earth, civilisation as we know it would still have a chance. Mars is one of the most attractive destinations. NASA, the United Arab Emirates, the private company SpaceX, and the organisation Mars One all have plans to send humans there. “Either we spread the earth to other planets, or we risk going extinct,” SpaceX founder Elon Musk said at a conference in 2013.
But not everyone agrees that colonising Mars or any other planet is such a great plan. The most common argument against going is that it’s just too expensive or dangerous. It will take huge amounts of money and other resources just to get people there,let alone set up a place for them to live. It’s not even clear if humans could survive on Mars. One of the biggest dangers is its deadly radiation that ruins the planet.
Maybe all the time and money people would pour into a Mars mission would be better spent on more urgent projects here on Earth, like dealing with poverty or climate change. Some experts argue that handling a problem like an asteroid (小行星) strike or a disease outbreak while staying here on Earth would be much easier and less expensive than surviving on a new planet.
In addition, moving to a new planet could harm or destroy anything that already lives there. Mars seems uninhabitable, but micro-organisms could exist on Mars. Human visitors may destroy these lives or permanently change or damage the Martian environment. Some feel that’s too much of a risk to take.
