AI（人工智能）products are not new. However, researchers have been working to improve the technology. Now virtual（虚拟的）assistants, like Siri and Alexa, can have short conversations with us. AlphaGo taught itself to play Go and became better than the top human players.

Now an AI system （系统）has been tasked with passing a multiple-choice （多项选择） exam. The goal is to improve machines' language understanding and logic（逻辑）with so-called computer vision（视觉）.

A system named Aristo was developed by the Allen Institute for AI, a lab in the United States city of Seattle. It recently passed an eighth-grade science exam taken by many US students. The New York Times reported. It correctly answered more than 90 percent of the questions. Then it was given a twelfth-grade exam, it scored more than 80 percent.

It's an example of the progress in AI development. Four years ago, 700 computer scientists tried to develop AI systems that could pass these kinds of exams. None scored higher than 60 percent.

Aristo was able to pass the exams because it can not only understand language but also use logical thinking to solve difficult problems. For example, it can understand what a forest fire is and how it could endanger animals like squirrels or make the food supply they need less.

The system used BERT, a kind of neural （神经的）network technology developed by Google, to answer the questions. BERT has "read" thousands of English articles. If it looks at a sentence with a missing word, it can correctly guess what the word is. With BERT’ s help. Aristo "read" many multiple-choice questions and answers. Over time, it was able to find logical patterns on its own.

It may still be in the earliest stages, said Jingjing Liu, a Microsoft researcher who has been working on similar technologies. “We can't compare this technology to real human students and their ability to reason."

However, Aristo's success means that Al systems are getting better at understanding users, and we might see improved search engines and hospital databases （数据库）in the near future.

1.Why did scientists develop Aristo?

A.To make better multiple-choice exams.

B.To improve AI's ability to teach itself.

C.To shorten the time AI needs to "read" information.

D.To improve the language understanding and logic of AI.

2.What can we know about Aristo from its exam results?

A.It was smarter than most US students.

B.It could only deal with science questions.

C.It was best at understanding English.

D.It did better than other AI systems in similar tasks.

3.The sixth paragraph mainly talks about how__________ .

A.Aristo teaches itself B.Aristo reads English articles

C.Google developed BERT D.difficult it was to design Aristo

4.What can be learned from Jingjing Liu's words?

A.AI will soon take the place of humans in many tasks.

B.Aristo still cannot compare to human reasoning skills.

C.Humans can't live without Al in the future.

D.Aristo can score more than 80 percent in a twelfth-grade exam.

Twelve animal head statues(生肖兽首雕像) are well-known treasures from Yuanmingyuan, or the Old Summer Palace. After Anglo-French troops(英法联军) broke into the old Summer Palace in 1860, a large number of national treasures, including the 12 animal head statues, were taken away.

On November 13th, 2019, a red bronze(铜) horse-head statue returned to Beijing. It was donated by Macao collector Stanley Ho and handed over to the National Cultural Heritage Administration(国家文物局) in Beijing.

“The broken link(链接) of history memory is connected again in this way,” Liu Yuzhu, director of the NCHA, told China Daily when she was in an interview.

“The return of the heritage(文物) holds the Chinese’s collective emotion(集体情感). People’s cultural confidence can be strengthened. It will also encourage more compatriots (同胞), both at home and abroad, to better protect the cultural heritage of our country.”

In the past 70 years, the Chinese government and many compatriots have made a great contribution to getting back lost Chinese heritage from foreign countries. Because of their hard work, the horse statue is the seventh of the 12 animal statues to be returned from other countries. Now the search is on for the remaining five: a dog, a rooster, a dragon, a sheep and a snake.

1.When were the 12 animal head statues taken away from Yuanmingyuan?

2.Who donated the red bronze horse-head statue to China last year?

3.What does Liu Yuzhu do?

4.How many animal head statues have returned to China?

5.Why do so many compatriots try to get back lost Chinese heritage?

We all know that foods will easily go bad if they get too warm. So we usually put them into our fridges to keep cool in hot weather. But can you make it without fridges?

In 1995，Abba，a teacher from Nigeria，found a cool way. His invention was called Pot-in-Pot Cooling System.

It uses two clay pots (陶罐). There is a smaller pot inside a lager one. The space between the two pots is filled with wet sand. Some foods can be kept fresh for several weeks in it.

Abba built five thousand pot-in-pot systems for the villagers in his hometown. Then people all over the country began using the invention. Soon it became popular with farmers in other African countries.

In 2000, Abba got a prize--the Rolex Award. If you are trying to do something to improve human life，you may have the chance to get this prize.
