They dont take lunch breaks or even get paid. Why? Theyre robots! Robots have long worked in fac
2、tories, helping to build cars and electronic appliances. But todays robots dont just do the jobs of people they actually look and act a lot like people. Kansei, a robot from Japan, has a plastic face covering 19 movable parts. The robot can make 36 facial expressions in response to different words.
3、Kansei shakes in fear at the word “war” and smiles when it hears the word “dinner” Researchers in Europe are going even further with iCub, a “baby” robot. They are teaching it to speak and hold conversations. The ability to interact is crucial for robots that will one day work closely with humans, s
4、ays robotics professor ChrisAtkeson. “This will require robots to understand what you say and how you are feeling and respond with appropriate emotions， ” he told WR News. Japanese scientist Minoru Asada agrees. He is building a robot called CB2 that acts like a real baby. “Right now, it only goes,
5、Ah, ah. But as we develop its learning function, it will start saying more complex sentences and moving on its own， ” Asada says. “Next generation robots need to be able to learn and develop by themselves.” Intelligent robot will become more important in the future, as populations age and the number
6、 of human workers declines in many countries. “Were going to have many more old people and not enough young people to care for them， ” says robot 【 精品教育资源文库 】 researcher Matthew Mason. “Technology can help the old people live at home longer, instead of going to nursing homes.” 篇章导读：本文是一篇说明文。介 绍了日本和

A To describe the functions of modern robots. B To pr
9、edict the future uses of robots. C To explain how a robot works. D To define what a robot is. 答案： A 段落大意题。根据文章第二段中的 “do the jobs of people” 和 “they actually look and act a lot like people” 可知机器人能做很多工作，而且外形和行为在很大程度上与人类相像，故推知本段主要介绍了现代机器人的功能。 3 How would the Kansei robot probably respond to the word “f
10、ire” ？ A Use languages to warn nearby humans. B Produce a worried look on his face. C Activate an automatic fire alarm. D Back up its memory files. 答案： B 推理判断题。根据文章第三段第二句 “The robot can make 36 facial expressions in response to different words.” 和最后一句中的关键信息 “Kansei shakes in fear at the word war and

B the capacity to interact with humans C the ability to learn independently D the willingness to work together 答案： C 细节理解题
12、。根据文章倒数第二段最后一句 “Next generation robots need to be able to learn and develop by themselves.” 可知，下一代的机器人能够独立学习和发展。 B 【 精品教育资源文库 】 The world is filled with extremely talented sand artists people that can masterfully carve up giant castles, sculptures and even paintings, using just sand and water. But
13、very few are as lovable as the Beachbot a robot which will keep the audience entertained as it moves around creating beautiful masterpieces. An automatic pressure control allows the robot to use the right amount of force on the soft sand. Seven motors ensure that the Beachbot can arrange the rake pr
14、ongs (尖头 ), allowing it to create “brush strokes” measuring two feet long and fifteen inches wide and tall. The rake can also be retracted at any time, enabling the robot to create the outline with multiple lines instead of a continuous one. Its three cushioned balloon like wheels not only help in p
15、ainting smoother curves, but also allow the robot to drive over the artwork, without ruining it. Of course all the skill and quickness are only possible because of the Beachbots incredible “brain” ， which has been programmed and turns images into paths that the robot can easily follow. An inbuilt la
16、ser scanner allows the detection of the four reflective poles that act as limits of its sand paintings. In addition, the inertial (惯性的 ) measurement unit allows the artist to make precise movements that become lines, patterns, and eventually beautiful shapes and images, some as big as 30 feet by 30
17、feet. While the Beachbots artwork, which it completes in a speedy quick ten minutes is certainly impressive, what is even more so is watching the robot create it a sight its inventors suitably describe as “a magical show” The Beachbot, which is still in the concept stage, is not quite ready for prod
18、uction. Thats because it requires manual (靠人工的 ) pulling, especially when creating larger sand paintings. In addition, its inventors imagine future Beachbots to be able to erase their own masterpieces, paint entire shorelines and even be proficient snow artists. 篇章导读：本文是一篇说明文。主要介绍了一款可以在沙滩上作画的沙滩 机器人。
19、 5 What does the underlined word “one” in Paragraph 2 refer to? A The outline. B The robot. C The line. D The rake. 答案： C 指代判断题。根据画线词前面的 “enabling the robot to create the outline with multiple lines instead of a continuous” 可知， one 指的是前面提到的线条。 6 How does the Beachbot know what to draw? A By using an
20、 inbuilt laser scanner to receive a signal of painting. B By arranging seven motors to design the painting patterns. C By using a program to change images into paths. D By depending on a man to guide it on the scene. 答案： C 细节理解题。结合第三段中的 “because of the Beachbots incredible “brain” ， which has been p
21、rogrammed and turns images into paths that the robot can 【 精品教育资源文库 】 easily follow” 可知，这个沙滩机器人由软件控制，能够把图案转变成路径从而进行作画。 7 What helps the Beachbot figure the boundaries to draw within? A The four reflective poles. B The inertial measurement unit. C The automatic pressure control. D The three cushione
22、d balloon like wheels. 答案： A 细节理解题。根据第三段第二句 “An inbuilt laser scanner allows the detection of the four reflective poles that act as limits of its sand paintings.”可知，这四个反射杆限制着它的作画范围。 8 Why isnt the Beachbot ready for production? A It cant complete paintings in a short time. B It cant create larger sa
23、nd paintings. C It cant draw a continuous line. D It cant move all by itself now. 答案： D 推理判断题。从最 后一段中的 “which is still in the concept stage” 及“because it requires manual ( 靠人工的 ) pulling” 可知，这个沙滩机器人还不能独自作画，即它还需要人工帮助。 . 七选五 Technology and kids: 4 ways to unplug A recent report by Common Sense Media found that over one third of 0 to 8 year olds studied had used a smartphone, iPad or a similar tablet.
