A couple of years ago,Ashok Goel was overwhelmed by the number of questions his students were asking in his course on artificial intelligence.Goel teaches computer science at Georgia Tech,sometimes to large classes,where students can ask thousands of questions online in a discussion forum.Professor Goel already had eight teaching assistants,but that wasn't enough to deal with the increasing number of daily questions from students.
When students feel confused and reach out with questions that go unanswered,their motivation to continue begins to fade.Professor Goel decided to do something to improve this situation and his solution was to create a virtual assistant named Jill Watson,which is based on the IBM Watson platform.
Goel and his team developed several versions of Jill Watson before releasing her to the online forums.At first,the virtual assistant wasn't too great.But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched.Then they began to feed Jill with the questions and answers.After some adjustments and enough time,Jill was able to answer the students' questions correctly 97% of the time.The virtual assistant became so advanced and realistic that the students didn't know she was a computer.The students,who were studying artificial intelligence,were interacting with the virtual assistant and couldn't tell it apart from a real human being.Goel didn't inform them about Jill's true identity until April 26.The students were actually very positive about the experience.
The goal of Professor Goel's virtual assistant next year is to take over answering 40% of all the questions presented by students on the online forum.The name Jill Watson will,of course,change to something else next semester.Professor Goel has a rosy outlook on the future of artificial intelligence,believing it will be widely applied.
(1)、What did Professor Goel find in the online course?A、The course was too difficult for students. B、Most students dropped out of his course. C、Students' questions were too many to handle. D、Assistants' capacity made students unsatisfied.(2)、What can be inferred about Jill Watson?A、She was easily identified as an AI. B、She turned out to be a great success. C、She was released online as the first version. D、She could answer all the questions correctly.(3)、Which is the closest in meaning to the underlined word "rosy" in paragraph 4?A、Hopeful. B、Sensitive. C、Adventurous. D、Cautious.(4)、What is the main idea of the text?A、An online computer course benefits students. B、An AI team develops online discussion forums. C、A knowledgeable AI assists in online education. D、A new outlook promises online AI development. -

Medha Gupta sometimes felt worried about making the 20-minute walk from the corner where the school bus dropped her off to her home in Herndon,Va.—especially during the colder months in winter.
Her mother,Divya Gupta had a suggestion:write an app.She was half-kidding,but Medha didn't take the challenge lightly.So she set out to work.
The result was Safe Travel,an app designed by Medha to help walkers feel more secure when they are travelling alone.Using the iPhone,a person can program it to send a warning to someone he or she trusts if he or she fails to arrive at a destination within a certain time.
It was the first iOS app that Medha had created.While she didn't think much would come from the project,her effort caught the eye of judges for the annual Congressional App Challenge,who selected her as the winner for Virginia's 10th District.
The App Challenge is designed to encourage students to consider careers in science,technology,engineering,and math by experimenting with coding and computer science.Winning students are invited to attend a reception on Capitol Hill in April and also received $250 in Amazon Web Service credits.
Medha said it took her about 40 hours to design,program and test the app.As for her next app?Medha's not certain.She temporarily has her app-development ambitions on hold because she's busy teaching herself artificial intelligence to help deal with improper words on social media platforms.Yes,she knows that there are teams of engineers probably doing the same thing.But she figures it can't hurt her own part,too.
"If we see something wrong with the world,we should do something about it," she said."After all,the only one stopping us from doing something is ourselves."
(1)、Why did Medha Gupta feel worried?A、It took a long time to walk home. B、It was difficult to write an app. C、It was colder than ever in winter. D、It was unsafe to walk home alone.(2)、What is Medha's attitude to the challenge of writing an app?A、Serious. B、Casual. C、Uncertain. D、Indifferent.(3)、What does the underlined phrase "on hold" in paragraph 6 mean?A、Developed. B、Delayed. C、Achieved. D、Satisfied. -

Grizzly bears,which may grow to about 2.5 m long and weigh over 400 kg,occupy a conflicted corner of the American psyche—we revere(敬畏) them even as they give us frightening dreams.Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see,and their answer is often the same:a grizzly bear.
"Grizzly bears are re-occupying large areas of their former range,"says bear biologist Chris Servheen.As grizzly bears expand their range into places where they haven't been seen in a century or more,they're increasingly being sighted by humans.
The western half of the U.S.was full of grizzlies when Europeans came,with a rough number of 50,000 or more living alongside Native Americans.By the early 1970s,after centuries of cruel and continuous hunting by settlers,600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies.In 1975,grizzlies were listed under the Endangered Species Act.
Today,there are about 2,000 or more grizzly bears in the U.S.Their recovery has been so successful that the U.S.Fish and Wildlife Service has twice attempted to de-list grizzlies,which would loosen legal protections and allow them to be hunted.Both efforts were overturned due to lawsuits from conservation groups.For now,grizzlies remain listed.
Obviously,if precautions(预防) aren't taken,grizzlies can become troublesome,sometimes killing farm animals or walking through yards in search of food.If people remove food and attractants from their yards and campsites,grizzlies will typically pass by without trouble.Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away."Our hope is to have a clean,attractant-free place where bears can pass through without learning bad habits,"says James Jonkel,longtime biologist who manages bears in and around Missoula.
(1)、How do Americans look at grizzlies?A、They cause mixed feelings in people. B、They should be kept in national parks. C、They are of high scientific value. D、They are a symbol of American culture.(2)、What has helped the increase of the grizzly population?A、The European settlers' behavior. B、The expansion of bears' range. C、The protection by law since 1975. D、The support of Native Americans.(3)、What has stopped the U.S.Fish and Wildlife Service from de-listing grizzlies?A、The opposition of conservation groups. B、The successful comeback of grizzlies. C、The voice of the biologists. D、The local farmers' advocates.(4)、What can be inferred from the last paragraph?A、Food should be provided for grizzlies. B、People can live in harmony with grizzlies. C、A special path should be built for grizzlies. D、Technology can be introduced to protect grizzlies. -

It should be one of the main goals in today's society to reduce plastic consumption.Though many believe recycling will solve the problem,and continue using plastic,it's actually the opposite.In 2013,254 million tonnes of trash was produced in the US alone,and only around 30% was recycled.This means the rest ended up in a landfill and will stay there for up to 1,000 years.
Now Asian countries,including Vietnam and Thailand,are looking for new ideas to avoid plastic.One of those ideas was a new,eco-friendly way to pack their goods by avoiding plastic packaging.One of Perfect Homes Chiangmai's team members noticed a creative way to reduce plastic that a supermarket called Rimping Supermarket was using.Little did he know that people all around the world would absolutely love this idea."I just entered to get a few items while we were waiting to sign some contracts with our lawyer,who was delayed.When I noticed the vegetables wrapped in banana leaves,I simply liked the idea.So I took a few pictures and posted them online," he said.
With more than 3.5 million views and over 17 thousand shares,the idea became something people can encourage more supermarkets to implement(实施).
Some have noticed that not everything on the shelves is completely plastic-free to which the supermarket responded that they are taking one step at a time,but it's not that easy.Many products come to the supermarkets pre-packaged and many companies are interested in wrapping their produce in plastic since it is the cheapest and the easiest option.
It's now up to the shoppers to show the supermarket which they prefer.If everyone opts for the banana leaf packaging,they will probably stop stocking the items in plastic.
(1)、What can we infer about recycling from paragraph 1?A、The author thinks highly of recycling. B、The US did a great job in recycling in 2013. C、Recycling has failed to solve the plastic problem. D、Recycling helps a lot in reducing plastic consumption.(2)、Why did the man go to Rimping Supermarket?A、To buy some items. B、To look for new ideas there. C、To take photos of their shelves. D、To sign a contract with a lawyer.(3)、What does the underlined phrase "opts for" in the last paragraph probably mean?A、Doubts. B、Increases. C、Dislikes. D、Chooses.(4)、What is the best title of the text?A、Leaf Packaging Spreads Rapidly B、Reducing Plastic Consumption C、Recycling Avoids Plastic Packaging D、A Good Option Makes a Difference -
