electrodes(電極) that sense the signals and reflect a persons instructionsscientists can instruct a humanoid(類人的) 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 robots 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 persons home.”The person wearing the electrode cap watches the robots movements on a computer screen through two cameras installed on and above the robot.When the robots cameras see the objects that are to be picked up they pass on the information to the users 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(計(jì)算程序) is used to decide where the robot will go.“One of the important things about this demonstration is that were 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.16What is special about the robot introduced in the passage?AIt is controlled by human thoughts.BIt can be made humanoid.CIt can be used to help the disabled.DIt has high intelligence itself.17Which of the following is true about the robot?AIt can move forward and backward and pick up two objects at the same time.BIt can move forward，pick up both objects and bring them to either location.CIt can only move forward，pick up one object and put it in one location.DIt can read all human thought demands and do as instructed.18What Rao said suggests that the new robot .Ais still at its early stage of developmentBwill be widely used in our daily routine

Canada and Canadians，and should best be considered North American.There are，of course，exceptions.Small­minded officials，rude waiters，and ill­mannered taxi drivers are hardly unknown in the US.Yet it is an observation made so frequently that it deserves comment.For a long period of time and in many parts of the country，a traveler was a welcome break in an otherwise dull existence.Dullness and loneliness were common problems of the families who generally lived distant from one to another.Strangers and travelers were welcome sources of diversion，and brought news of the outside world.The cruel realities of the frontier also shaped this tradition of hospitality.Someone traveling alone，if hungry，injured，or ill，often had nowhere to turn to except the nearest cabin or settlement.It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers.It reflected the harshness of daily life：If you didnt take in the stranger and take care of him，there was no one else who would.And someday，remember，you might be in the same situation.Today there are many charitable organizations which specialize in helping the weary travelers.Yet，the old tradition of hospitality to strangers is still very strong in the US，especially in the smaller cities and towns away from the busy tourists trails.“I was just traveling through，got talking with this American，and pretty soon he invited me to his home for dinner amazing.”Such observations reported by visitors to the US are not uncommon，but are not always understood properly.The casual friendliness of many Americans should be interpreted neither as superficial (膚淺的) nor as artificial (矯揉造作的) but as the result of a historically developed cultural tradition.As is true of any developed society，in America a complex set of cultural signals，assumptions and conventions affects all social interrelationships.And，of course，speaking a language does not necessarily mean that someone understands social and cultural patterns.Visitors who fail to“translate”cultural meanings properly often draw wrong conclusions.For example，when an American uses the word“friend”，the cultural implications of the word may be quite different from those it has in the visitors language and culture.It takes more than a brief encounter (邂逅) on a bus to distinguish between courteous convention and individual interest.Yet，being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.The Americans FriendlinessVisitors21.
