Humans：it’s time to abandon Earth or race extinction.

It could be the plot of a summer blockbuster (大片)，but this prediction isn’t science fiction.It’s a glimpse of the future，according to famous British scientist Stephen Hawking.

“I see great dangers for the human race，”he said in an interview with global forum Big Think.“There have been a number of times in the past when its survival has been a question of touch and go.”

“I believe that the long­term future of the human race must be in space，”he said.“It will be difficult enough to avoid disasters on planet Earth in the next hundred years，let alone the next thousand，or million.”

Hawking，who was awarded the Presidential Medal of Freedom last year，has recently voiced many concerns about the future of life on Earth.

“If aliens visited us，the outcome would be as much as when Columbus landed in America，which didn’t turn out well for the Native Americans，”he said.“Such advanced aliens would perhaps become nomads(游牧民)，looking to conquer and colonize whatever planets they can reach.”

But Hawking says he’s still hopeful for the future of humanity.He told Big Think，“We’ve made remarkable progress in the last hundred years.But if we want to continue beyond the next hundred years，our future is in space.”

Getting to another planet will prove a challenge，not to mention colonizing it for humanity.Katherine Freese from University of Michigan told Big Think，“The nearest star to Earth is Proxima Centauri (比邻星) which is 4.2 light years away.That means，if you were traveling at the speed of light the whole time，it would take 4.2 years to get there－or about 50，000 years using current rocket science.”

【文章大意】文章主要介绍了英国著名的科学家斯蒂芬·霍金对人类未来的预测。

1．Humans are advised to abandon Earth mainly because________．

A．aliens will take up our home planet soon

B．it was discussed in the forum Big Think

C．many scientists like Hawking are concerned about it

D．many disasters will happen on Earth

解析：选D。细节理解题。根据文章第四段中的“It will be difficult enough to avoid disasters on planet Earth in the next hundred years，let alone the next thousand，or million.”可

知，在接下来的几百年中地球上会有许多灾难发生。故答案为D。

2．Thinking about the future of humans，Hawking feels that________．

A．humans can’t live on Earth any longer

B．Earth will not be habitable for humans

C．other planets are ready for humans to reach

D．aliens are the biggest future threat to humans

解析：选B。推理判断题。根据文章第七段中的“We’ve made remarkable progress in the last hundred years.But if we want to continue beyond the next hundred years，our future is in space.”可知，我们虽然在过去的几百年中取得了卓越的进步，但是如果我们要在接下来的几百年中继续延续这种进步，我们将来的生活空间在太空。据此可以推断出，未来地球将不再适合人类居住。故答案为B。

3．What is the writer’s key point in the last paragraph?

A．It is impossible to get to another planet in space.

B．It is urgent for Hawking to develop the space science.

C．The near future can’t see human’s move to another planet.

D．The planet Proxima Centauri is far away from Earth.

解析：选C。推理判断题。根据文章最后一段的内容可知，人类借助现在的火箭科学技术，短时间内是不可能到达离地球最近的Proxima Centauri(比邻星)的，所以人类搬去另外一个星球在不远的将来是不会实现的。故答案为C。

4．This passage is most probably taken from________．

A．a conference interview B．a science fiction

C．a history book D．a forum report

解析：选D。推理判断题。文章主要介绍了斯蒂芬·霍金对人类未来的预测，是在global forum Big Think上发表的自己的看法与观点，故文章最有可能摘自论坛报告。答案为D。
