2019年12月份大学英语四级阅读理解原文及考题如下：
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. This online course is a core requirement of Georgia Tech's online Master of Science in Computer Science program. Professor Goel already had 8 teaching assistants, but that wasn't enough to deal with the overwhelming number of questions from students.
Many students drop out of online courses because of the lack of teaching support .When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy 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 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill the questions and answers. After some adjustment 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 artificial intelligence 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 questions posed by students on the online forum. The name, Jill Watson,will of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gatesor Steve Wozniak.

A) It is a robot that can answer students' questions. B ) It is a course designed for students to learn online.

48.What do we learn about Jill Watson?
A) She turned out to be a great success B) She got along pretty well with students.
C) She was unwelcome to students at first. D) She was released online as an experiment. 49.How did the students feel about Jill Watson?
A) They thought she was a bit too artificial. B) They found her not as capable as expected.
C) They could not but admire her knowledge. D) They could not tell her from a real person.
50. What does Professor Goel plan to do next with Jill Watson?

赠：大众情人，难伺候，配不上Jessica：Hey 怡茹, what's your plan for the weekend?
YR: 我原来大学的同学组了个乐队，今晚在酒吧表演，怎么样？要不要一起来？Jessica: 那，得看乐队成员帅不帅呀?
YR: 那你一定得来! 我这些同学都是大学里的校草级人物，主唱更是人帅脾气好，大学的时候简直是大众情人啊!
YR: Lady killer? 女性...杀手?
Jessica: No! A lady killer refers to a man who's extremely charming and women just throw themselves at him. These guys are usually very good-looking.
YR: 这简直就是我那个同学的写照！Every girl dreamt of dating him in college. He's such a lady killer! 尽管如此，他人却特别随和，一点也不难伺候! 不像我男朋友，动不动就不高兴，我简直受够了!
YR: High maintenance? 高级维修?我倒不用维修我男朋友...
Jessica: Haha Yiru, when you say someone is high-maintenance, it means he or she is really hard to satisfy.
YR: 哦，我懂了，就是难伺候！My boyfriend is definitely high-maintenance. He's constantly complaining, and can easily get upset!
Jessica: I'm sorry Yiru. You know what? Maybe you will have a shot with that lady killer classmate.
YR: 我？我可配不上他。

对了，这个“配不上”用美语怎么说？
a nice girl like you deserves someone awesome! I don't think any guy is out of YOUR league!
YR: 呵呵，谢谢你Jessica! 那你晚上跟我一起来哦!
Jessica: Sure. I'll go with you. Before we get ready for the party, tell me what you've learned today!。
