Question

  Mind control Imagine looking at something and being able to move it just by using your brain!That is exactly what the new technology called BrainGate can do 一 with the help of a robotic arm,anyway.

   BrainGate is. the idea of Professor John Donoghue and his team of researchers at the Brown Institute for Brain Science,USA. BrainGate is attached directly to the brain. First of all,gold wires are put into the part of the brain that controls movement. These are then connected to a small computer chip(芯片) . When the person thinks about different movements,this creates electrical signals,which are picked up by the chip. After this,the signals that are created by the brain are sent back to a computer,which changes the signals into movements. Finally,the computer uses the robotic arm to carry out these movements. BrainGate can already be used to write an e-mail or play computer games,just by brain power.

   The technology has already cost millions of dollars to develop and when it is available for use,it will probably cost thousands of dollars per person. There are still many challenges ahead for Donoghue nd his team. They are currently planning a mini wireless version,which will allow people to be connected to the computer at all times. Donoghue also dreams of using this technology to help disabled people who can't move their arms or legs. He plans to connect BrainGate directly to their own paralysed limbs(癱瘓的胳膊或腿) .This will mean that the person can control their own body again,without relying on a robotic arm.

   This research is attracting the military's (軍方的) attention as well. However,it is easy to understand why scientists might be concerned about how thought-controlled machines could be used by the military.

32. What does the underlined word “These” in Paragraph 2 refer to?

   A. Wires. B. Brains.

   C. Thoughts. D. Movements.

33. According to the text,what is one of BrainGate's disadvantages?

   A. It is too expensive.

   B. It needs improvement.

   C. It is difficult to control.

   D. It produces few movements.

34. How will Donoghue help disabled people?

   A. By making BrainGate smaller.

   B. By developing a wireless version.

   C. By attaching BrainGate to their bad limbs.

   D. By replacing their limbs with robotic ones.

35. What does the military think of thought-controlled machines?

   A. They could be useful.

   B. They could lead to disasters.

   C. They would be in mass production.

   D. They would face fierce competition.

Answer 1

32. A 35. A

(科普知識與現代技術)

本文是說明文。文章介紹了思想控制器——大腦之門。利用該裝置，人們可以通過大腦直接控制機械手臂的運動。

32. A.篇章結構題。根據第二段中的gold wires are put into the part of the brain that controls movement …then connected to a small computer chip可知，首先是把一些金線跟控制運動的那 部分大腦連接，然后再把“這裝線”跟一個小的 電腦芯片連接。

33. 4.推理判斷題。根據第三段中的The technology has already cost millions of dollars to develop and when it is available for use,it will probably cost .thousands .of dollars per person 不難 看出，該技術十分昂貴，可能會限制它的使用。

34. G。細節理解題。稂據第三段中的Donoghue also dreams of using this technology to help disabled people who can* t move their arms or legs. He plans to connect BrainGate directly to their own paralysed limbs 可知，Donoghue 打算把 大腦之門直接連接到殘疾人癱瘓的四肢上。

35. A.推理判斷題。根據最后一段中的This research is attracting the military’s attention as well 及 how thought-controlled machines could be used by the military可推測，軍方對思想控制 器感興趣是因為認為它們有用。
