From self-driving cars to deep sea explorers, more and more of humans’ tasks are being taken over by robots. But technology doesn’t stop there. In mid-August, reported the BBC, scientists from Cambridge University developed a robotic system that meant a robot could “build other robots, each one better than the previous(以前的) generation”.

The BBC noted that “those concerned about machines taking over the world shouldn’t worry”.

However, over 1,000 scientists and numerous artificial intelligence (AI, 人工智能) researchers－including UK astrophysicist Stephen Hawking and Apple cofounder Steve Wozniak of the US-brought the danger of fully autonomous weapons(自主武器), known as “killer robots”, to our attention earlier this summer.

“If any major military(軍事的) power pushes ahead with AI weapon development, a global arms race is inevitable(不可避免的),” warned an open letter released at the International Joint Conference on Artificial Intelligence held in Buenos Aires, Argentina.

Unlike drones(無人機), which need a human hand, this kind of robot would have some decision-making abilities and the ability to act by itself. While what the BBC called these “solders that never sleep” could help reduce battlefield deaths, they might also make countries more likely to go into battle, which would lead to more deaths overall, noted the scientists. The risks, they said, could be far greater than those posed by nuclear weapons.

Scientists called for a “ban on offensive(攻擊性的) autonomous weapons beyond meaningful human control”, reported The Huffington Post.

In fact, in an interview with the BBC in 2014, Hawking warned that the “development of full artificial intelligence could spell the end of the human race”.

And according to the BBC, many leading thinkers have been thinking about the AI-powered killing machine of the not-too-distant future. “Killer robots could be here within years, not decades,” as Stuart Russell, professor of computer science at UC Berkeley, US, put it.

Authorities are gradually waking up to the risk of robot wars. Last May, for the first time, the United Nations brought governments together to begin talks on so-called killer robots in a hope of stopping such weapons while there is still time.

Meanwhile, there are scientists who are less worried. They believe all technologies have potential(潛力) for being used for good and evil ends, and argue that the ban called for by the open letter could close the door to developing AI technology that could save lives. “Technology can clearly do better than human beings in many cases,” Ronald Arkin, dean at the Georgia Institute of Technology in Atlanta, US, told The Christian Science Monitor. “If we are willing to turn over some of our decision making to these machines, we may actually get better outcomes.”

1.What does Steve Wozniak think the future robot technology might produce?

A. Artificial Intelligence. B. Autonomous weapons.

C. Soldiers that never sleep. D. Killing machines.

2.The underlined word “spell” in Paragraph 7 is closest in meaning to “______”.

A. cause B. prevent

C. reach D. change

3.What does Stuart Russell mean by saying “killer robots could be here within years, not decades.”?

A. Killer robots will visit UC Berkeley, US sooner than expected.

B. Killer robots will be produced and used sooner than expected.

C. Killer robots will speed up the development of AI in the near future.

D. Killer robots will kill these scientists in the near future.

4.What is the main idea of the text?

A. More and more of humans’ tasks are being taken over by robots.

B. Robots have decision-making abilities and the ability to act by itself.

C. Scientists called for a ban on the development of robot technology.

D. All technologies have potential for being used for good and evil ends.

In the middle of the 20th century people were worried about whales.The number of whales killed worldwide came up to 66,000 per year.However,people weren't worried about the whale as an endangered animal.Instead,they were worried about the whale industry,which would disappear if there were no whales.In 1946,the International Whaling Commission was established.It limited the whale hunting for every country and controlled the whale industry.But the commission recognized that the limitation wasn't enough.They set a worldwide law against hunting whales with only two exceptions: the hunt for scientific research and "aboriginal whaling".Aboriginal whaling allows some countries to hunt a limited number of whales because it is a part of their culture.Some countries like Japan and Norway don't care about the law;they make excuses to hunt whales and sell the products.They only care about the money.

Many fishermen complain that dolphins,also a kind of whale,steal their fish.Therefore,they kill thousands of them.In fact,this is not the truth.In reality there are so many fishermen who steal the fish from each other.Some whale hunters say that they catch the animals for scientists.They have to research what whales are eating.For that, they kill them and look into their stomach.The truth is that they only want to sell the meat.Today scientists want to observe live whales for their research.

Many whale families are not protected and thousands of them are killed.Nobody knows if all whale families would survive,even if humans end all whale hunting today.The pollution of the oceans increases fast and the poison gets into the bodies of the animals.Many of them get sick and die.The human being has killed 90%-95% of many whale families.Others are already extinct.

Today some international organizations try to protect whales.They make reports to explain how important and endangered whales are.Now people are becoming more interested in whales and a complete new industry has developed,whale watching,which you may want to learn about.

D. Because they live on hunting whales.

4.Why do many fishermen complain about dolphins?

According to a new US study, couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive as sons overall.

The research by Angelina Grigoryeva, a sociologist at Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members. 

Her analysis of the family networks of 26,000 older Americans concluded that gender(性別) is the most important predictor(預示物) of whether or not people will actively care for elderly parents. 

In a paper being presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men statistically likely provide less care. 

Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over-50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours. 

“Whereas the amount of elderly parent care daughters provide is associated with limitations they face, such as employment or childcare, sons’ caregiving is associated only with the presence or absence of other helpers, such as sisters or a parent’s spouse(配偶),” she explained. 

“Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.” 

“This suggests that sons pass on parent caregiving responsibilities to their sisters.” 

In the UK, the 2011 census(人口普查) showed that there are now around 6.5 million people with caring responsibilities – a figure which has risen by a tenth in a decade. 

But many are doing so at the risk of their own health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a full- time job are three times more likely to be struggling with ill health than their working counterparts(相對應的人) who are not carers.

1.What’s the most important factor to predict if people will actively care for the elderly?

A. Gender. B. Education.

C. Career. D. Family networks.

2.The US study finds that _______.

A. sons are twice as likely as daughters to care for parents in old age

B. having a sister makes men less likely to do their fair share

C. sons and daughters seem to give equal care to their parents

D. sons are unwilling to leave caregiving responsibilities to female family members

3.What does the author stress in the last paragraph?

A. People should give up their jobs to care for the elderly.

B. Many care providers work longer hours than others.

C. People shouldn’t pass on caring responsibilities to others.

D. Many care providers have potential health problems.

4.The author develops the text by _______.

A. explaining social networks of careers

B. describing people’s experiences

C. analyzing various research and data

D. comparing different gender behavior
