Students from the School of Physics took part in a volunteer activity organized by the Student Union to assist elderly people in the neighborhood this weekend, bringing them great laughter and joy.

With the increasing awareness of the aging of population, the whole society sets out to take better care of and show more respect for our senior citizens for their lifelong dedication and commitment to our society. In response to the call, this weekend a group of volunteers went to the local community to communicate with the elderly and help them with some housework. Much pleased at their coming, all the elderly people expressed their sincere thanks for young volunteers' company. In the light of many adult children not being able to visit their aging parents frequently, many old people have to endure loneliness. Thus, what matters most to than is the company and listening attentively is just a good idea.

The Student Union expressed their willingness to sponsor more meaningful activities like this to serve our society with college students' passion and talents.

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 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 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 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. The name Jill Watson will, of course, change to something else

佐治亚理工学院的 Ashok Goel 教授开发了一种人工智能助教，以帮助处理在线课程“基于知识的人工智能”中的大量学生问题。该在线课程是佐治亚理工学院计算机科学在线硕士课程的核心要求。Goel 教授已经有八名助教，但这还不足以应付学生每天提出的海量问题。

许多学生因为缺乏教学支持而退出在线课程。当学生感到孤立或困惑并提出未得到解答的问题时，他们继续学习的动力开始减弱。Goel 教授决定采取一些措施来补救这种情况，他的解决方案是创建一个名为 Jill Watson 的虚拟助手，它基于 IBM Watson 平台。

Goel 和他的团队在将 Jill Watson 发布到在线论坛之前开发了多个版本。起初，虚拟助手并不太好。但是 Goel 和他的团队找到了在线讨论论坛，以查找自课程推出以来所提出的所有 40,000 个问题。然后他们开始用问题和答案喂吉尔。经过一些调整和充足的时间，吉尔能够正确回答学生问题的概率为 97%。虚拟助手变得如此先进和现实，以至于学生们都不知道她是一台电脑。正在学习人工智能的学生正在与虚拟助手互动，无法将其与真人区分开来。Goel 直到 4 月 26 日才告诉他们吉尔的真实身份。学生们实际上对这次经历非常积极。

Goel 教授的虚拟助理明年的目标是接管回答学生在在线论坛上提出的所有问题的 40%。吉尔沃森这个名字当然会在下学期改成别的名字。Goel 教授对人工智能的未来前景比埃隆·马斯克、斯蒂芬·霍金、比尔·盖茨或史蒂夫·沃兹尼亚克要乐观得多。

Textbooks represent an 11 billion dollar industry, up from $8 billion in 2014. Textbook publisher Pearson is the largest publisher -- of any kind -- in the world.

It costs about $1 million to create a new textbook. A freshman textbook will have dozens of contributors, from subject-matter experts through graphic and layout artists to expert reviewers and classroom testers. Textbook publishers connect professors, instructors and students in ways that alternatives, such as open e-textbooks and open educational resources, simply do not. This connection happens not only by means of collaborative development, review and testing, but also at conferences where faculty regularly decide on their textbooks and curricula for the coming year.

It is true that textbook publishers have recently reported losses, largely due to students renting or buying used print textbooks. But this can be chalked up to the excessively high cost of their books -- which has increased over 1,000 percent since 1977. A restructuring of the textbook industry may well be in order. But this does not mean the end of the textbook itself.

While they may not be as dynamic as an iPad, textbooks are not passive or lifeless. For example, over the centuries, they have simulated (模拟) dialogues in a number of ways. From 1800 to the present day, textbooks have done this by posing questions for students to answer inductively (归纳性地). That means students are asked to use their individual experience to come up with answers to general questions. Today's psychology texts, for example, ask: "How much of your personality do you think you inherited?" while ones in physics say: "How can you predict where the ball you tossed will land?"

Experts observe that "textbooks come in layers, something like an onion." For an active learner, engaging with a textbook can be an interactive experience. Readers proceed at their own pace. They "customize" their books by e

本题解析：

教科书代表着110亿美元的产业，高于2014年的80亿美元。教科书出版商皮尔逊是世界上最大的出版商——任何类型的出版商。

创建一本新教科书的成本约为 100 万美元。一本新生教科书将有数十名贡献者，从主题专家到图形和布局艺术家，再到专家评审员和课堂测试员。教科书出版商以开放电子教科书和开放教育资源等替代品无法做到的方式将教授、教师和学生联系起来。这种联系不仅通过协作开发、审查和测试来实现，而且还通过教师定期决定来年教科书和课程的会议来实现。

的确，教科书出版商最近报告了亏损，主要是由于学生租用或购买使用过的印刷教科书。但这可以归结为他们的书籍成本过高——自 1977 年以来已经增加了 1,000% 以上。教科书行业的重组很可能是有序的。但这并不意味着教科书本身的终结。

虽然它们可能不像 iPad 那样充满活力，但教科书并不是被动的或毫无生气的。例如，几个世纪以来，他们以多种方式模拟对话。从1800年到现在，教科书都是通过提问归纳性地回答学生的。这意味着要求学生利用他们的个人经验来回答一般问题。例如，今天的心理学课文会问：“你认为你继承了多少个性？”而物理学中的人说：“你怎么能预测你扔的球会落在哪里？”

专家观察到“教科书层层叠叠，就像洋葱一样”。对于积极的学习者来说，阅读教科书可以是一种互动体验。读者按照自己的节奏进行。他们通过接触不同的层次和联系来“定制”他们的书籍。突出显示、便利贴、狗耳朵和其他技术允许进一步定制，学生更重视印刷书籍而不是数字形式的书籍。

Finally, some good news about airplane travel. If you are on a plane with a sick passenger, you are unlikely to get sick. That is the __26__ of a new study that looked at how respiratory (呼吸道) viruses __27__ on airplanes.

All other passengers had only a very __28__ chance of getting sick, according to the findings. Media reports have not necessarily presented __29__ information about the risk of getting infected on an airplane in the past.

正确答案：

【参考范文】

Nowadays, we are witnessing a surge in technology in all aspects. People’s views vary greatly on whether this trend are causing people’s addiction. In my point of view, being immersed in a sea of technology will definitely harm people’s life, even make them become addicted.

For one thing, despite the fact that some technologies, are invented to help people, many of them are made to attract people’s attention and make profit. Unaware of this, one would easily get trapped in the world of technology, like computer technology, and lose himself. For another, since most of us are living in a highly digitalized society, few can escape from the influence of their friends and families who are already addicts to technology.

All in all, without strict government restriction and proper guidance on computer technology, people are exposed to the risk of being addicted. It is also necessary for everyone to resist this temptation and maintain good self-discipline.

本题解析：

【参考译文】

如今，我们正目睹科技在各个方面的飞速发展。对于这种趋势是否会导致人们上瘾，人们的看法大相径庭。在我看来，沉浸在技术的海洋中肯定会伤害人们的生活，甚至使他们上瘾。

一方面，尽管有些技术是为了帮助人们而发明的，但其中许多技术是为了吸引人们的注意力和盈利。没有意识到这一点，一个人很容易陷入科技、尤其是电脑科技的世界中，迷失自我。另一方面，由于我们大多数人生活在一个高度数字化的社会，很少有人能够摆脱他们已经沉迷于科技的朋友和家人的影响。

总而言之，如果没有政府的严格限制和对于科技的适当指导，人们将面临上瘾的危险。每个人都必须抵制这种诱惑，保持良好的自律。

Directions: For this part, you are allowed 30 minutes to write an essay on whether violent video games online will cause students’ violent behaviors. You should write at least 120 words but no more than 180 words.

查看答案开始考试

正确答案：

Nowadays, violent video games online have become increasingly popular among students. Many people hold the view that such violent games can cause propensity for violence while others think that those games are only created for fun.

In my opinion, such games do lead to a tendency of violence to some extent. On the one hand, students are easier to be misguided by some violent behaviors in those games since they are not mature enough to tell right from wrong. Consequently, they will probably imitate these behaviors in real life. On the other hand, some students can do what are forbidden in real life while permitted in these games, during which they gradually develop the quality of violence and become easier to make aggressive behaviors when conflicting with others.

To sum up, I think we should reduce our time spent on those violent video games and do more meaningful things to live our life to the fullest.

【参考译文】

如今，网络暴力游戏在学生中越来越流行。许多人认为这种暴力游戏会导致暴力倾向，而另一些人则认为这些游戏的开发初衷只是为了好玩。

在我看来，这类游戏在某种程度上确实会导致暴力倾向。一方面，学生很容易被这些游戏中的一些暴力行为所误导，因为他们还不够成熟，不能辨别对错。因此，他们可能会在现实生活中模仿这些行为。另一方面，一些学生可以在游戏中做一些在现实生活中被禁止而在游戏中被允许的事情，在游戏中他们逐渐发展出了暴力的品质，在与他人发生冲突时更容易做出攻击性的行为。

总之，我认为我们应该减少花在暴力游戏上的时间，做更多有意义的事情来充实我们的生活。
