Experts believe that the best time to teach kids language skills is when they are babies. Most of the time the task is easily accomplished with parents reading or talking to their babies. However, in some cases that is not possible due to busy work schedules or when kids are born deaf. Now, an adorable blue-eyed robot, a human avatar, and some high-tech neuroscience may be able to assist parents with this important developmental task.

The Robot AVatar thermal-Enhanced system, or RAVE, is the brainchild of a team of researchers led by Laura-Ann Petitto, an educational neuroscientist, at Washington, DC's Gallaudet University. The learning process begins when the robot's camera, which is focused on the baby's face, detects tiny changes in his/her body temperature. This, combined with the baby's facial expression, causes the robot to turn its head and guide the baby's attention to a computer screen, on which a human avatar starts to communicate with the baby, much like what a parent would do. For example, if the baby points towards the screen, the avatar might respond, "Are you pointing to me?" and follow that up with a nursery rhyme, fairy tale, or some essential social communication, all in American Sign Language(ASL). The "conversation" continues until the kid loses interest.

The researchers, who have been testing the system for three years, found that babies as young as 6 to 8 months old began to move their hands in a rhythm similar to ASL after interacting with RAVE for just a few minutes. Petitto says natural language, whether communicated through speech or sign, activates the same parts of the brain and believes the rhythmic motions prove that the babies are learning the essential elements of communication.

What sets this technique apart from other methods, such as showing educational videos or television shows, is its interactive nature and real-time response to the baby's actions. The researchers say that while it is too early to determine the system's long-term influence on baby communication, the initial response has been very encouraging. Next, they plan to introduce an avatar that can both sign and speak to babies.

1. What does Paragraph 2 mainly talk about?
A.How babies learn ASL effectively.B.How parents educate their babies.
C.How robots talk and read to babies.D.How the RAVF system works.
2. What indicates babies are learning with the help of the RAVE system?
A.Interest in videos and TV shows.B.Changes in their body temperature.
C.Improvement in their natural language.D.Hand movements in a rhythm like ASL.
3. What do the researchers think of the RAVE system?
A.Promising.B.Impractical.C.Satisfactory.D.Disappointing.

文章大意:这是一篇记叙文。文章主要讲述了作者曾经因为父亲带他看美丽的流星而久久不能忘怀,作者认为像父亲这样有非凡“天赋”的父母,能够为孩子们打开一扇门,带领他们进入辉煌的新领域。

【推荐1】One summer night, a boy felt himself lifted from bed by his father. Dazed with sleep, he saw stars flashing across the heavens. “What is it?” the child whispered. “Shooting stars. They come every year in August.” Decades have passed, but I remember that night still, because I was the fortunate boy whose father believed a new experience was more important than an unbroken night’s sleep.

Some parents like my father have the gift of opening doors for their children. This art of adding dimensions to a child brings the reward: the marvelous moment when the spark bursts into a flame that will burn brightly on its own one day. At a Golf Association tournament, a ten-year-old girl played creditably. “How long have you been interested in golf?” someone asked. “I got it for my ninth birthday,” she said.“ Your father gave you a set of clubs?” “No,” she said, “he gave me golf.”

I have a friend, a psychiatrist, who says there are two types of people: those who think of life as a privilege and those who think of it as a problem. The first type is enthusiastic and energetic. The other type is suspicious and self-centered. And he adds, “Tell me about your childhood and I can tell you which type you are likely to be.”

The real purpose, then, of trying to open doors for children is to build eager and outgoing attitudes, which is the most valuable legacy we can pass on to the next generation. But why don’t we work harder at it? Probably because sometimes we don’t have the awareness or the selflessness or the energy. And yet, for those of us who care what becomes of our children, the challenge is always there but the opportunities also come repeatedly. Many years have passed since that night. And next year, when August comes with its shooting stars, my son will be seven.

A.To show parental impact on children’s passion.
B.To suggest hobbies always start from the small.
C.To highlight the importance of diverse experiences.
D.To prove true passion usually arises from the reward.
2. What do the underlined words “adding dimensions to” in Paragraph 2 mean?
A.Setting an example for.B.Broadening the horizons of.
C.Providing attentive care for.D.Narrowing the possibilities of.
3. What will the author’s psychiatrist friend agree with?
A.Stability in upbringing builds confidence.
B.Parenting styles requires professional guidance.
C.Childhood experience determines adult happiness.
D.One’s personality is related to childhood experiences.
4. What can we infer from the last paragraph?
A.The author is always addicted to shooting stars.

文章大意:本文是一篇议论文。 文章主要介绍了“选择悖论”这一现象,即过多的选择会让人们感到困惑和不满,从而降低消费者的满意度。文章还介绍了“最大化者”和“满足者”的区别,以及心理学和行为经济学在解决这一问题中的作用。

【推荐2】Imagine you need milk, so you go to the grocery store to pick some up, only to find there are dozens of options. These days, you have to make a decision on not only the percentage of fat you want, but also what source you want your milk to be coming from: cows, soybeans... You have no idea what milk to pick. There are so many choices that you are confused.

This phenomenon is known as the paradox (悖论) of choice and it is becoming a concern in the modern world, where more and more options are becoming easily available to us. While we might believe that being presented with multiple options actually makes it easier to choose one that we are happy with, and thus increases consumer satisfaction, having too many options actually requires more effort to make a decision and can leave us feeling unsatisfied with our choice.

The idea was popularized by American psychologist Barry Schwartz when he published his book, The Paradox of Choice: Why More Is Less. Schwartz, who has long studied the ways in which economics and psychology intersect (交叉), became interested in seeing the way that choices were affecting the happiness of citizens in Western societies. He identified that the range of choices that we have available to us these days is far greater than that people had in the past; however, consumer satisfaction has not increased as much as traditional economics theories might expect.

Schwartz identified that the paradox of choice carries the most consequence for people that are maximizers. Maximizers, unlike satisficers, are concerned with making the best choice instead of simply making a choice that they are happy with. When there are many options available to maximizers, it becomes harder for them to determine which is the best, which can cause them to feel a great deal of regret after they have made a choice.

Instead of believing that freedom of choice is unlimited, Schwartz advocates that the role of psychology and behavioral economics should be to find the kind of limitations on freedom that can lead to the greatest level of happiness within society.

1. What’s the author’s purpose in mentioning buying milk in paragraph 1?
A.To lead in the topic.
B.To draw a conclusion.
C.To show that we have more choices when shopping.
D.To indicate that people pay greater attention to health when shopping.
2. What does the paradox of choice suggest?
A.More options mean less satisfaction.
B.Consumer satisfaction has greatly increased.
C.People are happy with more choices.
D.Modern people are happier than their ancestors.
3. What can be learned about satisficers?
A.They aim for the very best.B.They tend to follow their feelings.
C.They often regret their decisions.D.They have trouble making a decision.
4. What does Schwartz suggest people do?
A.Hold on to their beliefs.B.Accept their own behavior.
C.Give up freedom.D.Limit their own choices.

文章大意:本文是一篇说明文。文章介绍了计算机专业学生在开发项目时实际上是在进行研究,他们需要收集数据、分析并得出结论,以证明他们的设计与开发过程系统且有效。同时本文也出自一本书的引言,说明了书中的主要内容。

【推荐3】Some readers majoring in computing discipline might ask, “What’s all this got to do with me? I just want to develop a computer system, build a website or create a computer animation and write a report about it, not collect and analyse data or make arguments.”

The response is that designing and creating any kind of computer-based product is still a form of research, which requires finding or generating data, analysing it and drawing conclusions. The research question is. “Is it possible to develop a computer-based product to do X?” In order to define that question fully (for example, What is X? Why is it important to have a computer system to do X?), and then to answer it, you will have to gather data about the computer-based product required, generate your own data to document how and why you designed and implemented the product, and test the computer-based product and obtain user or viewer feedback, which will involve more data generation and analysis.

Ultimately, you will have to convince the readers of your report that you went about the design and development tasks in a systematic way, finding, generating and analysing appropriate data, so that you could draw conclusions about whether or not you could indeed develop a computer system to do X.

Of course, some systems development is fairly trivial, for example, using a PC-based software package to build a database to keep track of your music collection. To satisfy academics as a valid (有效的) piece of research, the computer-based product must contribute something new, for example, the system includes some new functions not previously automated using Information Technology (IT), or its design is based on a new theory or algorithm, or the system exhibits some new artistic ideas. Viewing the design and creation of computer systems as research is discussed more fully in Chapter 8.

As explained above, increasingly researchers who build computer-based products are also being encouraged to evaluate their products in use. Effectively, a new research question is being added to design and creation projects — What happens when the computer-based product is used in practice or viewed by an audience? To answer that question, researchers have to use one or more of the other strategies and data generation methods described in this book.

1. Why does the author begin the text with quotes from readers?
A.To provide evidence.B.To lead in the topic.
C.To present the argument.D.To review what is discussed.
2. Why is designing and creating a computer-based product viewed as research?
A.It has the same process as a research.
B.It serves the same purpose as a research.
C.It needs the same qualifications as a research.
D.It faces the same difficulties as a research.
3. What is the closest in meaning to “trivial” in paragraph 4?
A.Abstract.B.Important.C.Simple.D.Creative.
4. Where is the text most probably taken from?
A.A book review.B.A book report.
C.The introduction to a book.D.The main body of a book.
