Ⅱ.阅读理解
Scientists have created a way to control a robot with signals from a human brain.
By generating the proper brainwaves—picked up by a cap with electrodes(电极)that sense the signals and reflect a person's instructions—scientists can instruct a humanoid robot to move to specific locations and pick up certain objects.
The commands are limited to moving forward, picking up one of two objects and bringing it to one of two locations.The researchers have achieved 94 percent accuracy between the thought commands and the robot's movements.
“This is really a proofofconcept demonstration，”said Rajesh Rao，a researcher from the University of Washington who leads the project.“It suggests that one day we might be able to use semiautonomous robots for such jobs as helping disabled people or performing routine tasks in a person's home.”
The person wearing the electrode cap watches the robot's movement on a computer screen through two cameras installed on and above the robot.
When the robot's cameras see the objects that are to be picked up they pass on the information to the user's computer screen.Each object lights up randomly on the computer screen.When a person wants something to be picked up and it happens to light up，the brain registers surprise and sends this brain activity to the computer and then to the robot as the choice object.The robot then proceeds to pick up the object.
A similar program is used to decide where the robot will go.
“One of the important things about this demonstration is that we're using a ‘noisy’ brain signal to control the robot，”Rao said.“That means we can only obtain brain signals indirectly from sensors on the surface of the head，and not where they are generated deep in the brain.As a result，the user can only generate highlevel commands such as indication which object to pick up or which location to go to，and the robot needs to be autonomous enough to be able to execute such commands.”
In the future，the researchers hope to make the robot more adaptive to the environment by having them carry out more complex commands.
16．What is special about the robot introduced in the passage?
A．It is controlled by human thoughts.
B．It can be made humanoid.
C．It can be used to help the disabled.
D．It has high intelligence itself.
17．Which of the following is TRUE about the robot?
A．It can move forward and backward and pick up two objects at the same time.
B．It can move forward, pick up both objects and bring them to either location.
C．It can only move forward，pick up one object and put it in one location.
D．It can read all human thoughts and do as instructed.
18．What Rao says in the eighth paragraph suggests that the new robot________.
A．is still at its early stage of development
B．will be widely used in our daily routines soon
C．is autonomous enough to complete complex commands
D．is only limited to doing routine work at home
19．The sixth paragraph mainly describes________.
A．how the robot controls a person's action
B．how the robot picks up the right object
C．how the person controls the robot
D．how the robot finds out where to go
Ⅲ.任务型阅读

The Key Factor in Solving Robot’s Intelligence Problem
C.
Comparison between Humans and Robot
D.

20. ________
Robot, it is a word that seems very modern, a word that creates a strong mental picture, a picture of something that looks and acts like a human. Robots are not human. Of course, they are machines.
21. ________
The word robot, and robots themselves, are less than 100 years old. But humans have been dreaming of real and imaginary copies of themselves for thousands of years. Early people made little human statues out of clay. And they cut wood and stone to look like humans.
22. ________
What is the future of robots? The goal of scientists is to create a true humanlike robot. Some experts have described this robot of the future as one that can act independently with the physical world through its own senses and actions. Humans have the ability to see, hear, speak and solve problems. Engineers have built robots that have one or two of these abilities. But it takes a number of big expensive computers to make the robots work.
23. ________
The biggest problem in creating a humanlike robot is copying human intelligence. The way the human mind works is almost impossible to copy. A simple computer can do mathematical problems far beyond the ability of even the smartest human mind. But the human mind is better than a thousand supercomputers at speaking, hearing and problemsolving. Several American and Japanese companies are working to develop the senses of sight and touch for robots. The development of these senses will make robots much more useful.
24. ________
However, the most important human ability—the most difficult to copy—is problemsolving. An intelligent robot must be able to change the way it acts when it faces an unexpected situation. Humans do it all the time. Computers must do it for robots. This means computers must have a huge base of information about many things. They must be able to find quickly the needed information in their systems. And they must make choices about how to act. So far, this is beyond the ability of computers.
答案
课时作业(三十二)
Ⅰ.1.B 考查非谓语动词。“演员等待被发现”， 用被动， “发现”发生在“等待”之后， 所以用不定式。
2．B 考查非谓语动词。表示被动、已完成，用过去分词作原因状语。句意：由于写得匆忙，作文到处都是错误。
3．D 考查非谓语动词。the one指代前面提到的buildings与repair是动宾关系，由前半句房屋需要修缮可知修缮这个动作发生在need之后，所以用to be repaired。
4．D 考查非谓语动词。句意：现在人们有时把他们的垃圾分开，以便很容易被重复利用。“再利用”是指将来发生的动作，而且是被动的。故选D。
5．A 考查非谓语动词。由next Friday可知时间是将来，party是被举行，故选A。
6．B 考查虚拟语气。desire 后面的从句要用虚拟语气，即should ＋动词原形，其中should可以省略。
7. D 考查非谓语动词。句中省略了it is，补充完整为：What a victory it is to be envied by those…。句意：被富有而又自大的女人所妒忌是一种胜利。
8．D 考查交际用语。with pleasure “乐意地，愉快地”，表示同意。
9．D 考查embarrass的用法。feel在此处用作系动词，后应跟形容词作表语。embarrassing “令人难堪的”；embarrassed “窘迫的，尴尬的”。依据语境应选D。
10．A 考查动词词义辨析。句意：这种娱乐设施的说明指南说，除非由大人陪同，小孩子不可以独立操作器械。accompanied by an adult由大人陪同。
11. D 考查形容词辨析。句意：只要我们坚持在公众中传播科学知识，所有的奇怪的信仰一定会从我们的生活中消失。A意为“必要的，必需的”；B意为“重要的”；C意为“困难的，艰难的”；D意为“注定的”。从语意和搭配看，这里用固定短语be bound to do sth.表示“一定会……”。故选D项。
12．B 考查动词辨析。alarm意为“使警觉，使惊恐，惊动”。句意：两头狮子从动物园跑出来的消息令当地人很惊恐。delight使高兴；satisfy使满足；inspire鼓舞，激励。
13. C 考查冠词用法。句意：世界博览会就像文化交流的一个大舞台，它将全世界的人们紧密联系起来。第一空表泛指，第二空表特指。
14. B 考查交际用语。前句表示提出建议，根据应答句的后一分句可知应答句选B，意思是：我乐意。
15．C 考查交际用语。在英语中对于别人提出的帮助请求，通常用with pleasure(非常乐意)回答，my pleasure用来表示你帮对方做了某事后，别人向你表示感谢后你的回答用语，意思是“这是我乐意做的”。
Ⅱ.本文属于科普读物。文章介绍一种通过人的思维来控制机器人以及实验的一些情况。
16．A 细节理解题。文章介绍的这种机器人能够按照人脑所发出的信息去把需要的东西捡起来并把它放到需要的位置，因此其突出特点是能够被人的思维控制。
17．C 细节理解题。从第三段的介绍可知，这种机器人只能向前移动，捡起两个物体中的一个，然后把它放到两个地点中的一个。
18．A 推理判断题。从文章中Rao所说的话推断，这种机器人现在还只能接受一些浅层次的指令，因此还处于发展的初级阶段。
19．B 主旨大意题。第六段主要介绍这种机器人怎样获得信息并把物体捡起来。
