高三英语单项填空简单题查看答案及解析

Helping yourself to a cup of coffee may seem like a small, everyday thing. But it is not the case if you are quadriplegic (四肢瘫痪). Quadriplegics have lost the use of all four limbs. Thanks to a project organized by John Donoghue of Brown University, in Rhode Island, and his colleagues, quadriplegics have hope.

One of the participants in his experiments, a 58-year-old woman who is paralyzed and unable to use any of her limbs, can now pick up a bottle containing coffee and bring it close enough to her mouth to drink from it using a straw. She does so using a thought-controlled robotic arm fixed to a nearby stand. It is the first time she has managed something like that since she suffered a stroke, nearly 15 years ago.

Arms are more complicated pieces of machinery than legs, so controlling them via electrodes (多波段电极) attached to the skin of someone’s scalp (头皮) is not yet possible. Instead, brain activity has to be recorded directly. And that is what Dr Donoghue is doing. Dr Donoghue and his team have had small, multichannel electrodes implanted in the parts of the motor cortexes (运动皮质) of participants’ brains associated with hand movements.

Dr Donoghue and his team decoded signals from their participants’ brains as they were asked to imagine controlling a robotic arm making present movements. The woman and other volunteers were then encouraged to operate one of two robot arms by thinking about the movements they wanted to happen. When the software controlling the arms detected the relevant signals, the arms moved appropriately. The arm that the woman used to help herself to a drink is a lightweight device developed by DLR, German’s Aerospace Centre, as part of its robotics program.

Dr Donoghue and his colleagues have thus shown that a mechanical arm can be controlled remotely by the brain of a person with paralysis. Controlling an arm that is attached to the individual’s body will be trickier, but in time even that may be possible. In the meantime, a robotic arm attached to a wheelchair will be a real soon.

1.What does the underlined word “that” in Paragraph3 refer to?

A.Controlling a robotic arm via electrodes attached to the scalp.

B.Recording the activity of brain and implanting electrodes.

C.Controlling a robotic leg via electrodes attached to the scalp.

D.Controlling a mechanical arm attached to the individual’s body.

2.Which statement may the author agree with?

A.Thanks to the research by Dr Donoghue and his colleagues, a paralyzed woman can get herself a drink.

B.The woman in the experiment drinks a bottle of coffee with a robotic arm attached to her scalp.

C.The woman is encouraged to control the mechanical arm by moving her body.

D.The robotic arm the woman used is remoted by DLR.

3.What’s the author’s attitude to the future of the robotic arm attached to quadriplegic?

A.Pessimistic. B.Objective.

C.Controversial. D.Optimistic.

4.What’s the main idea of the text?

A.Quadriplegics can use the artificial limbs developed by Dr Donoghue and lead a good life by themselves.

B.The newly-developed thought-controlled robotic arms can help the paralyzed in their daily life.

C.Scientists have invented a kind of robotic arm attached to the individual’s body.

D.A quadriplegic can be on his feet again due to the new invention.
