From
self-driving cars to carebots (care＋robots) for elderly
people, rapid development in technology has long represented a possible threat
to many jobs normally performed by people. But experts now believe that almost
50 percent of occupations existing today will be completely unnecessary by 2025
as artificial intelligence continues to change businesses.
"The
next fifteen years will see a revolution in how we work, and a revolution will
necessarily take place in how we plan and think about workplaces," said
Peter Andrew, Director of Workplace Strategy for CBRE Asia Pacific.
A
growing number of jobs in the future will require creative intelligence, social
skills and the ability to use artificial intelligence.
The
report is based on interviews with 200 experts, business leaders and young
people from Asia Pacific, Europe and North America. It shows that in the US
technology already destroys more jobs than it creates.
But
the report states:" Losing occupations does not necessarily mean losing
jobs—just changing what people do." Growth in new jobs could occur as
much, according to the research.
"The
growth of 20-to-40 person companies that have the speed and technological
know-how will directly challenge big companies，"
it states.
A
2014 report by Pew Research found 52 percent of experts in artificial
intelligence and robotics were optimistic about the future and believed there
would still be enough jobs in the next few years. The optimists pictured "a
future in which robots do not take the place of more jobs than they create,"
according to Aaron Smith, the report's co-author.
"Technology
will continue to affect jobs, but more jobs seem likely to be created. Although
there have always been unemployed people, when we reached a few billion people
there were billions of jobs. There is no shortage of things that need to be
done and that will not change," Microsoft's Jonathan Grudin told
researchers.
36．We can infer from the text that in the future ____.
A．people will face many difficulties
B．people will take up more creative jobs
C．artificial intelligence will threaten people's lives
D．most jobs will be done in traditional workplaces
37．According to the report, ____.
A．people won't necessarily lose jobs
B．big companies will face fewer challenges
C．small companies will win against big companies
D．most people will become interested in technology
38．What is the attitude of most experts in artificial intelligence and robotics to the future？
A．Mixed. B．Worried. C．Hopeful. D．Doubtful.
39．Jonathan Grudin's words in the last paragraph suggest that ____.
A．there will be enough jobs for people
B．things will change a lot in a few years
C．many people will become unemployed
D．technology will totally change future jobs
【答案】36．B
37．A
38．C
39．A
【解析】【分析】本文是一篇说明文，人工智能改变商业结构，专家称约一半的职业到2025年将会消失。
【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇社会类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，从而选出正确答案。
36．考查推理判断。根据第二段中的“The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces”未来15年，我们的工作方式将发生革命，我们如何规划和思考工作场所，必然会发生一场革命；以及第三段内容可知，未来人们需要从事更具有创造性的工作，故选B。
37．考查细节理解。根据第五段中的“Losing occupations does not necessarily mean losing jobs—just changing what people do. ”可知，职业消失并不意味着工作必然丢失——它仅仅改变了人们做的事情。故选A。
38．考查推理判断。根据倒数第二段中的“52 percent of experts in artificial intelligence and robotics were optimistic about the future”52% 的人工智能和机器人方面的专家，对未来持乐观态度；以及“The optimists pictured'a future in which robots do not take the place of more jobs than they create，'”乐观主义者认为“一个机器人不会取代他们创造的工作岗位的未来”。可知，大多数人工智能和机器人领域的专家对未来持乐观态度。故选C。
39．考查推理判断。根据最后一段中的“but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs.”但似乎会创造更多的就业机会。虽然一直都有失业的人，当我们达到几十亿人的时候，有数十亿的工作机会。可知，微软公司的Jonathan Grudin认为，更多的工作会被创造出来，人们会有足够的就业机会。故选A。

The
year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our planet, but
two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth's atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the Earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperatures around the world fall to almost zero. Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then about 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn't live through the cold climate that followed and they died out. Will we meet the same end
40．What is mainly described in the passage
A．A historical discovery. B．An event of imagination.
C．A research on space. D．A scientific adventure.
41．When the first piece hits the South Atlantic, it causes ____.
A．an earthquake B．damages to cities
C．an Earth explosion D．huge waves
42．Why can't the northern half of the Earth escape for long
A．Because the land is covered with water.
B．Because the light and heat from the sun can not reach the Earth.
C．Because people there can not live at the temperature of zero.
D．Because wars break out among countries.
43．By giving the example of dinosaurs, the author tries to prove ____.
A．animals could not live in the cold climate
B．what happened 65 million years ago was an invented story
C．the human beings will die out in 2094
D．the Earth could be hit by other objects in space
【答案】40．B
41．D
42．B
43．D
【解析】【分析】本文是一篇记叙文，描述了在2094年如果一颗彗星的碎片撞向地球，人类可能面临终结。
【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇故事类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，从而选出正确答案。
40．考查细节理解。根据第一段的时间2094以及下文的内容可知，文章描述了人类在2094年可能会遭遇的灾难。这些事情只是一种想象而已。故选B。
41．考查细节理解。根据第二段中“Huge waves are created and spread outwards from the hole. ”巨浪从洞中涌出，向外扩散。故选A。
42．考查推理判断。根据第三段可知，南半球的数以百万计的人已经死了，而北半球也逃脱不了这种厄运。因为太阳照不到地球，地球上的温度几乎降到了零度。庄稼遭到了破坏，食物缺乏导致战争的爆发。故选B。
43．考查推理判断。根据最后一段中的“Could it really happen？”以及“Will we meet the same end？”两个问题的提出可知，作者是想通过举恐龙这一例子说明地球很有可能再次遭遇撞击。故选D。

The
year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our planet, but
two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth's atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the Earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperatures around the world fall to almost zero. Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then about 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn't live through the cold climate that followed and they died out. Will we meet the same end
