| 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. |
| 1．What is special about the robot introduced in the passage? |

| 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. |

| 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 |
| 4．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 |

| Easy Ways to Keep Your Brain Sharp Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit and that can be a very annoying thing.__1__ Read on for some techniques worth trying. 1．__2__ People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study.__3__ Something as simple as setting a goal to have a weekly coffee date with a friend will do.There's evidence that people who have a purpose in life or who are working on long or shortterm goals appear to do better.In other words, keep your brain looking forward. 2．Go for a walk. Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels.In fact, exercise produces chemicals that are good for your brain.__4__ 3．Learn something new. Take a Spanish class online, join a drawing club, or learn to play cards.A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind.But the best thing for your brain is when you learn something new and are physically active at the same time.__5__ Or go dancing with your friends. |
| A．Focus on the future. B．This can be especially harmful to the aged. C．It should be something like learning gardening. D．So take a few minutes each day to do some reading. E．But don't worry if your schedule isn't filled with lifechanging events. F．Luckily, research shows there is a lot you can do to avoid those moments. G．In other words, when you take care of your body, you take care of your brain. |
