Ⅱ.阅读理解Scientists have created a way to control a robot with signals from 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(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-of-concept 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 semi-autonomous 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 high-level 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
19.The sixth paragraph mainly describes________.
A.how the robot reacts to a person’s instructions
B.how the robot picks up the right object
C.the functions of the computer
D.how the robot finds out where to go
20.The underlined word “registers” in the passage can be best replaced by “________”.
A.receivesB.showsC.writes downD.picks up
Ⅲ. 任务型读写
The e-book is a downloadable book that can be put right onto your e-reader, certain cellphones and computers. There are websites that sell e-books where you can buy them and load them right onto whatever device you choose. The e-book makes it possible to take reading with you, without the mess of carrying dozens of books around with you.
However, not all book authors are okay with having their books in digital format. The creator of Harry Potter says that her books will never be an e-book, and many just like her feel the same way. However, there are lots of authors who absolutely love the idea and feel it’s the next step to keep books alive.
The e-book can be loaded onto an e-reader which is a mini-device that is slim and small just like a cellphone. It usually has a touch pad screen and can hold a few hundred books. That’s perfect news for people who travel on planes or go on holidays and would love to take a collection with them but wouldn’t carry fifty hard covers.
The other great thing about e-readers is that you can read e-books on them quickly and there’s no need for two hands to hold the book and turn the page; it is more convenient for people to read it. Most of them also have a night light, so if you want to read at night but don’t want a big light on to wake your partner, the e-reader is ideal.
Websites that sell e-books have their sites looking just like ordinary book store websites. There is a list for best-sellers and a new release (发行) section. There is also clearance e-books on sale and gift certificates available to give to someone who also downloads e-books. They seem to cost the same amount of money as buying a paperback book.
