You have probably read about robots replacing human labor as automation takes root in one industry after another. But a new report suggests humans are not the only ones who might lose their jobs.

In New Zealand, farmers are using drones (无人机) to herd (放牧) and monitor livestock (牲畜), assuming a job that highly intelligent dogs have held for more than a century. The robots have appropriated one of the animal’s effective tools: barking, Radio New Zealand reports. The DJI Mavic Enterprise, a $3,500 drone favored by farmers, has a feature that lets the machine record sounds and play them over a loud speaker, giving the machine the ability to imitate its canine counterparts.

Corey Lambeth, a shepherd on a sheep and beef farm, told RNZ the machines are surprisingly effective. “That’s the one thing I’ve noticed when you’re moving cows and calves: the old cows stand up to the dogs, but with the drones, they’ve never done that.” he said. That means the drones move livestock faster, with less stress, than the dogs do.

Farmers told RNZ the drones come in handy for more than just herding cows and sheep. The robots allow farmers to monitor their land from afar, monitoring water and feed levels and checking on livestock health without disturbing the animals.

Jason Rentoul told RNZ last spring that a two-hour herding job that used to require two people and two teams of dogs could be accomplished in 45 minutes using a single drone.“Being a hilly farm where a lot of stuff is done on foot, the drones really saved a lot of man hours,” he said. “The drone does the higher bits that you can’t see (from the ground). Before using drones, you would (otherwise) have to walk half an hour to go and have a look and then say, “Oh, there are no sheep here.”

Farmers all over the world are using drones. In South Africa, they monitor crop health from above, which boosts harvests, according to CNN. In California, winemakers use drones equipped with sensors to grow healthier grapes, according to MIT Technology Review. Because drones fly closer to the ground, they are able to provide high-resolution images that are less expensive than hiring someone to fly over a field in a manned aircraft, the publication reported.

For now, farmers in New Zealand say, some dogs are already learning to work alongside drones, identifying the machines as more co-worker than enemy. Besides, there is still a need for herding dogs, primarily because they have a longer life span than drones, can work in bad weather and do not require an electrical socket (插座) every few hours to recharge.

1.The underlined part in Paragraph 2 probably refers to“_____”.

A.farmers’ order

B.dogs’ barking

C.the call of sheep

D.the sound of loud speakers

2.What’s the advantage of drones according to the farmers?

A.They can be purchased at a low price.

B.They put less stress on livestock.

C.They can do more than one task efficiently.

D.They help them monitor weather conditions.

3.What does Paragraph 6 mainly talk about?

A.The secret to harvesting healthier grapes.

B.The application of drones in global agriculture.

C.How drones provide less expensive but clearer images.

D.Why manned aircraft are losing appeal for

4.It can be inferred from the last paragraph that ________.

A.drones function normally in extreme weather

B.farmers are troubled by where to charge drones

C.the herding dogs show no enthusiasm to drones

D.drones cannot replace dogs entirely at the moment

高三英语单项填空中等难度题查看答案及解析

Machines might one day replace human laborers in a number of professions,but surely they won't ever replace human artists.Right?

Think again.Not even our artists will be safe from the inevitable machine takeover,if a new development in artificial intelligence by a team of researchers from Rutgers University and Facebook's A.I.lab offers a clue of what's to come.They have designed an A.I.capable of not only producing art,but actually inventing whole new aesthetic styles similar to movements like impressionism or abstract expressionism,reports.The idea,according to researcher Marian Mazzone,was to make art that is "novel,but not too novel."

The model used in this project involved a generator network,which produces the images,and a discriminator network,which "judges" whether it's art.Once the generator learns how to produce work that the distributor recognizes as art,it's given an additional directive: to produce art that doesn't match any known aesthetic styles.

"You want to have something really creative and striking—but at the same time not go too far and make something that isn't aesthetically（美学地）pleasing,"explained Ahmed Elgammal.

The art that was generated by the system was then presented to human judges alongside human-produced art without showing which was which.To the researchers' surprise,the machine-made art scored slightly higher overall than the human-produced art.

Of course,machines can't yet replace the meaning that's infused in works by human artists,but this project shows that artist skill sets certainly seem duplicatable by machines.

What will it take for machines to produce content that's infused with meaning?That might be the last A.I. frontier.Human artists can at least hang their hats in that field...for now.

"Imagine having people over for a dinner party and they ask,‘Who is that by?’And you say,‘Well,it's a machine actually’.That would be an interesting conversation starter,"said Kevin Walker.

1.What is implied in the first paragraph?

A. Artists won't be replaced by AI.

B. AI can produce new styles of art.

C. AI is totally at a loss about impressionism.

D. AI fails to reflect abstract expressionism.

2.What did Marian find in his study?

A. AI can copy the skills of artists.

B. AI can combine content with meaning.

C. AI can make art aesthetically unpleasant.

D. AI can please human judges with its art.

3.What does the underlined phrase “hang their hats” mean?

A. Discover.　　 B. Hold.

C. Struggle.　　 D. Survive.

4.What Kevin said in the last paragraph tells us that_____.

A. she uses machines to cook for a party　　 B. she likes to join in a dinner party

C. she expects the arrival of AI　　 D. she cares about the starter of a chat

For decades，the San Francisco Bay area has been the heart of the computer technology industry．Many of the biggest technology companies have their headquarters in the area called Silicon Valley．But the area has not always been associated with charity(慈善)．

Now，a new generation of entrepreneurs(企业家)appears to be changing Silicon Valley．One example is Marc Benioff，a donor(捐赠者)，who has called on wealthy donors to give more to their communities．He also is the founder of Salesforce．com，a computer services company in San Francisco who has helped build a children’s hospital and given millions of dollars to non-profit organizations in the city．

Money from the technology industry has also started to change the face of charity．Benjamin Soskis writes about the history and ideas behind charity in America．His articles have appeared in The Atlantic magazine and a number of major publications．He says，traditionally，donors have given after they spent much of their lives building up wealth．Usually donors are in their 70s．But an increasing number of people appearing on the list of top donors are younger than 40 years of age．Benjamin Soskis says that is something new．“There’s a whole new model that’s appearing in which people give and accumulate at the same time．”

Some of the young donors on this year's top 50 list have started to change in the way people see charity．That is especially the case in the San Francisco area，where giving money and making money appear to be coming together．“I think it's fair to say that charity is now a part of the Silicon Valley identity．”
