【题目】 Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. Professor Goel already had eight teaching assistants, but that wasn’t enough to deal with the overwhelming number of daily questions from students.

Many students drop out of online courses because of the lack of teaching support. When students feel ignored or confused and reach out with questions that go unanswered, their motivation to continue begins to taper off. Professor Goel decided to do something to improve this situation and his solution was to create a virtual assistant named Jill Watson.

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 sufficient 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 posed by students on the online forum. Professor Goel has a much rosier outlook on the future of artificial intelligence.

【题目】 Only 48% of school age children in the United States get 9 hours of sleep most weeknights, according to a new research being presented at the American Academy of Pediatrics ( AAP) 2019 National Conference & Exhibition in New Orleans. An abstract of the study, "Sounding the Alarm on the Importance of Sleep” , will be presented on Saturday, Oct. 26, at the Ernest N. Morial Convention Center in New Orleans.

“Long-term sleep loss is a serious public health problem among children,” said abstract author Hoi See Tsao, MD, FAAP. "Insufficient sleep among adolescent, for example, is associated with physical and mental health consequences including increased risk of depression and obesity and negative effects on mood, attention and academic performance.”

Dr. Tsao said, "Our research shows that children who get enough sleep are more likely to flourish(健康成长)in comparison to children with insufficient sleep."

Researchers analyzed responses from parents and caregivers of 49,050 children ranging in age from 6-17 years old in the combined 2016-2017 National Survey of Children's Health. They answered questions on how many hours of sleep a randomly selected child in their household slept on an average weeknight. For the study, sufficient sleep was defined as sleeping greater than or equal to 9 hours on an average weeknight.

The researchers found that sufficient sleep, was positively associated with several individual flourishing markers, as well as the combined childhood flourishing measure. The researchers also identified risk factors associated with insufficient sleep, which included lower levels of parental or caregiver education, the presence of mental health conditions and so on.

Dr. Tsao said the study strengthened the importance of increasing efforts to help children get the recommended amount of sleep for their age. “Interventions like these may help children demonstrate more measures of childhood flourishing, enhance their development and give them brighter futures, " she said.

【题目】 When “Rise of the Planet of the Apes” was first shown to the public last month, a group of excited animal activists gathered on Hollywood Boulevard. But they weren’t there to throw red paint on fur-coat-wearing film stars. Instead, one activist, dressed in a full-body monkey suit, had arrived with a sign praising the filmmakers: “Thanks for not using real apes ()!”

The creative team behind “Apes” used motion-capture (动作捕捉) technology to create digitalized animals, spending tens of millions of dollars on technology that records an actor’s performance and later processes it with computer graphics to create a final image (图像). In this case, one of a realistic-looking ape.

Yet “Apes” is more exception than the rule. In fact, Hollywood has been hot on live animals lately. One nonprofit organization, which monitors the treatment of animals in filmed entertainment, is keeping tabs on more than 2,000 productions this year. Already, a number of films, including “Water for Elephants,” “The Hangover Part Ⅱ” and “Zookeeper,” have drawn the anger of activists who say the creatures acting in them haven’t been treated properly.

In some cases, it’s not so much the treatment of the animals on set in the studio that has activists worried; it’s the off-set training and living conditions that are raising concerns. And there are questions about the films made outside the States, which sometimes are not monitored as closely as productions filmed in the States.

1Why did the animal activists gather on Hollywood Boulevard?

A.To see famous film stars.

B.To oppose wearing fur coats.

C.To raise money for animal protection.

D.To express thanks to some filmmakers.

2What does paragraph 2 mainly talk about?

A.The cost of making “Apes.”

B.The creation of digitalized apes.

C.The publicity about “Apes.”

D.The performance of real apes.

3What does the underlined phrase “keeping tabs on” in paragraph 3 probably mean?

A.Listing completely.

B.Directing professionally.

C.Promoting successfully.

D.Watching carefully.

4What can we infer from the last paragraph about animal actors?

A.They may be badly treated.

B.They should take further training.

C.They could be traded illegally

D.They would lose popularity.

【题目】 A housewarming party is a special party to be held when someone buys or moves into a new apartment or house. The person who bought the house or moved is the one who throws the party.
