【題目】 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.

【1】What problem did Professor Goel meet with?

A.Students’ questions were too many to deal with.

B.Teaching assistants were not professional at all.

C.Many students were lack of interest in his class.

D.He felt confused about how to teach online.

【2】Which of the following best explains the underlined phrase in Paragraph 2?

A.grow dramaticallyB.increase sharply

C.decrease graduallyD.decline unreasonably

【3】What do we learn about Jill Watson?

A.She could answer all questions without mistakes.

B.She turned out to be a great success.

C.Her performance was remarkable all the way.

D.Her true identity was still a secret to students.

【4】What’s the main idea of the text?

A.A robot gives an online course.

B.Virtual assistant is getting popular in school.

C.Robots will replace humans in online classes.

D.One Georgia Tech’s teaching assistant isn’t human.

【答案】

【1】A

【2】C

【3】B

【4】D

【解析】

這是一篇說明文。文章說明了佐治亞理工學(xué)院的Ashok Goel教授開發(fā)了一個(gè)人工智能助教，以幫助處理在線課程中大量的學(xué)生問題，即基于知識(shí)的人工智能。文章還介紹了這一做法的產(chǎn)生的原因是學(xué)生的問題太多，教授無法處理。以及這個(gè)名為Jill Watson的虛擬助理投入的過程，以及學(xué)生們對(duì)此的反饋。

【1】細(xì)節(jié)理解題。根據(jù)第一段中Professor Goel already had eight teaching assistants, but that wasn’t enough to deal with the overwhelming number of daily questions from students.可知Goel教授已經(jīng)有了8名助教，但這還不足以應(yīng)付學(xué)生每天提出的大量問題。由此可知，Goel教授遇到的問題是學(xué)生的問題太多了，無法處理。故選A。

【2】詞義猜測(cè)題。根據(jù)上文When students feel ignored or confused and reach out with questions that go unanswered, their motivation to continue begins to可知當(dāng)學(xué)生感到被忽視或困惑，和一些問題沒有被回答時(shí)，他們繼續(xù)學(xué)習(xí)的動(dòng)力就開始逐漸taper off了，由此可知，劃線短語意思為C項(xiàng)“逐漸減少”。故選C。

【3】推理判斷題。根據(jù)第三段中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.可知虛擬助理變得如此先進(jìn)和現(xiàn)實(shí)，以至于學(xué)生們不知道她是一臺(tái)電腦。這些學(xué)生正在學(xué)習(xí)人工智能，他們與虛擬助手進(jìn)行互動(dòng)，無法將其與真人區(qū)分開來。Goel直到4月26日才告訴他們Jill的真實(shí)身份。學(xué)生們對(duì)這次經(jīng)歷給予肯定。由此可推知，虛擬助理Jill Watson很非常成功。故選B。

【4】主旨大意題。根據(jù)第一段中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.可知佐治亞理工學(xué)院的Ashok Goel教授開發(fā)了一個(gè)人工智能助教，以幫助處理在線課程中大量的學(xué)生問題，即基于知識(shí)的人工智能。結(jié)合文章還介紹了這一做法的產(chǎn)生的原因是學(xué)生的問題太多，教授無法處理。以及這個(gè)名為Jill Watson的虛擬助理投入的過程，以及學(xué)生們對(duì)此的反饋。這篇文章的主旨是介紹一個(gè)佐治亞理工學(xué)院不是人類的虛擬助教Jill Watson。故選D。

【題目】 CARMEL VALLEY - You don’t necessarily have to be older to be a Good Samaritan. Take Carmel Valley resident, Daniella Marie Benitez, 14, who is not your average teen. Daniella is helping Tijuana families have roofs over their heads — one family at a time.

It began in 2017 while she was volunteering for Build A Miracle and building a home for a family in need in Tijuana, Mexico. Daniella found it so fulfilling that she took the lead in building another home with the support of her family and friends.

To date, she has raised $32,000 for her cause and recently headed to Tijuana to begin building her team’s second home.

“It has been an unbelievable experience,” Daniella, a freshman at Cathedral Catholic High School in San Diego, said. She learned about Build A Miracle through her previous school, Notre Dame Academy. It is a nonprofit organization that takes a family in need from a shack (棚屋) to a new home with electricity, bedrooms, kitchen and a bathroom. It has built more than 350 homes since 1999.

During this most recent trip to Tijuana, Daniella and her team poured the foundation (基金) for the second new home. Additionally, she used her other volunteering position as a member of KIDBOX’s Kids board of directors to help distribute $10,000 worth of brand new KIDBOX clothing to her BAM community’s kids.

Between BAM and KIDBOX, the busy teen said she would continue to volunteer both locally and in Mexico to “stay humble.” She isn’t about to stop helping others; in fact, it’s something she treasures. “I’ve been working with BAM for about a year and a half. I got involved at the end of seventh grade when my previous school sponsored the building of a school sponsored home; my mom forced my family and me to go down to TJ to actually help build the house,” she said. “Meeting the family and seeing their delight and relief when they walked into their new home was priceless and is what inspired me to keep doing this.”

【1】What made Daniella stand out among teens?

A.Her constant efforts to help those less fortunate.

B.The building of a school sponsored home.

C.Her attempt to raise a fund for her cause.

D.The organizing of Build A Miracle.

【2】How did Daniella make connections between BAM and KIDBOX?

A.She encouraged KIDBOX to collect money for BAM.

B.She promoted a donation to BAM from KIDBOX.

C.She held leading positions in both organizations.

D.She built a platform for them to communicate.

【3】What chiefly inspired Daniella to keep helping others?

A.The support from her parents.B.Carmel Valley’s traditional values.

C.Tijuana families’ happy reactions.D.The influence from her previous school.

【題目】閱讀下面材料，根據(jù)其內(nèi)容和所給段落開頭語續(xù)寫兩段，使之構(gòu)成一篇完整的短文。續(xù)寫的詞數(shù)應(yīng)為150左右。

It seemed I’d done everything I’d ever wanted to do in my life, but I had one regret. I was born in 1898, the oldest of five kids. Papa couldn’t spare me to go to school, so I worked in the fields with him till I was 21 years old.

Everywhere I went, I learned some hard lessons about what happens to a man who even can’t read the alphabet. People cheat you out of wages. They sell you a ticket to one city, take your money and hand you a ticket to somewhere else.

By 1928, I’d been wandering for nine years. I met a woman named Elzenia. We fell in love, married and moved to Dallas, where I got work fixing roads for the city. When Amelia, the oldest of our seven children, first went to school, I took my wife aside. “Elzenia,” I said. “I don’t want the kids to know I can’t read or write.”

In 1938, one day my boss called me in. “George,” he said. “No one knows those machines like you do. I’d like to promote you.” But my thrill and surprise were cut short when he said, “Fill out this application and we’ll get you a raise.” I couldn’t admit the truth. I thanked him and walked out of his office. I did stay right where I was, until I turned 65 and my boss made me retire. But I didn’t stop working. For the next 25 years, I lived a happy life, but it still seemed to me like something was missing.

A young fellow handed me a piece of paper. It’s information about adult education classes. People can learn to read and write. Now I’m 102. I thought of my friends and neighbours and what they might think if they found out I couldn’t read. After all these years, my secret would be out. But all my life I’ve wanted to read. It was high time for action.

Paragraph 1: The young man drove me to a huge building and led me into a spacious classroom, which was crowded with elderly people like me.

Paragraph 2: I’m still going to school.
