Professor Ashok Goel of Georgia Tech （佐治亞理工學院） developed an artificially intelligent teaching robot, knowledge-based artificial intelligence, to help handle the enormous number of students' questions in the online class. This online course is a core requirement of Georgia Tech's online Master of Science（理科碩士） in Computer Science program. 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 isolated 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 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 （獲得） the online discussion forum to find all the 40,000 questions that had ever been answered 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. So advanced and realistic was the virtual assistant 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. Not until April 26 did Goel inform them about Jill's true identity. To his great delight, the students were actually positive about the experience.

Next year, Professor Goel's virtual assistant will be supposed to take over answering 40% of all the 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 artificial intelligence than, say, Elon Musk, Stephen Hawking,Bill Gates or Steve Wozniak.

寫作導引

本次的寫作任務是寫一篇文章給?？陡?，要求學生描述虛擬助教的應用情況、對虛擬助教的看法以及建議等，并且至少需要使用一個非謂語或部分倒裝句。這些寫作要求和所給語篇的主題語境是緊密相關的。 我們可以通過整合同主題閱讀材料的內容和語言，梳理寫作思路和積累素材。

（三）提出建議的核心表達

1. had better do sth 最好做某事

With the advancement of..., it has become a trend that...（現(xiàn)象）

I am positive about... because of the following reasons. First, ... Second, ... Third, ...(觀點) I believe that it will be better if we do sth in order to/so as to... (建議)

四、語篇過手

根據以上提供的主題、主題表達和語篇結構，我們可以寫出文章的第一、二段。第一段描述虛擬助教的應用情況，第二段表達個人的觀點并提出建議。 總詞數控制在80左右。

同時，學習運用前文閱讀材料中出現(xiàn)的非謂語或部分倒裝。尤其要注意表達的內在邏輯關系，需要注意使用恰當的連詞。
