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(类人 的) 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 proof- concept demonstration, said Rajesh Rao, researcher from the of” a

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 movements 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 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.The robot then proceeds to pick up the object. A similar algorithm(计算程序) 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,not where they are generated deep in the brain.As a result,the user can only generate highlevel commands such as indicating 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 robots 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 thought demands and do as instructed. 18.What Rao said suggests that the new robot________. A.is still at its early stage of development B.will be widely used in our daily routine soon C.is autonomous enough to complete complex commands D.is only limited to doing routine work at home

A.receives Ⅲ.阅读表达 Some expressions have made a jump from sports events to everyday life.One such expression is fall guy.A fall guy is the person who someone decides will be the loser or victim. The first fall guys were men who wrestled for money.At the end of the 19th century, wrestling was a very popular sport in the United States.Wrestling competitions were held not only in big cities but also at country fairs and traveling shows.As wrestling gained in popularity,it became less like a sport because the winners of the matches were arranged in advance.The wrestlers knew—before the match—which one of them would be the winner. The goal in wrestling is to hold the shoulders of your opponent down against the floor.This is called a fall.Sometimes,one of the wrestlers would be paid before the match to take the fall.He would agree________—the fall guy. Today,a fall guy is anyone who is tricked into taking the blame for the crime or wrongdoing of someone else.There are fall guys in many situations—people who publicly take the blame when something goes wrong. A fall guy takes the rap for something wrong or illegal.He accepts responsibility and punishment for what someone else did.He may have something to do with the situation,but is not the person who should be blamed. The word “rap” has meant blame for several hundred years.The expression “to take the rap” was first used about one hundred years ago.Another similar expression is “bum rap”.A person receives a bum rap if he is found guilty of a crime but is really innocent. 21.What does the expression “a fall guy” refer to according to Paragraph 1? (Please answer within 15 words.) 22.Which sentence in the passage is the closest in meaning to the following one?
