二、阅读理解
根据短文内容，从题中所给的A、B、C、D四个选项中选出最佳选项，并完成第5小题。
Have you ever dreamed of writing down your thoughts without holding a pen or typing on a keyboard? This amazing idea is no longer just a fantasy, but a real achievement made by students from Tianjin University. They successfully used Brain-Computer Interface (BCI) technology to “write” the Chinese character “fu” (which means blessing).
“The character is actually written by a robotic arm, and the arm is controlled directly by the researchers’ thoughts,” explained Professor Xu Minpeng from Tianjin University. In their laboratory, two researchers wore special caps with sensors. They focused their eyes on a computer screen and tried to “write” the character with their minds. First, a computer received and analyzed signals from their brainwaves. Then, it sent orders to the robotic arm, which finally wrote “fu” on a piece of red paper. The whole process took the researchers about three minutes.
BCI technology is not new. It has been applied in many different fields. In 2016, Chinese astronauts Jing Haipeng and Chen Dong tested a BCI system in the Tiangong II space lab, and it was the first time that such a system was used in space. Scientists hope that in the future, astronauts can use BCI technology to finish difficult tasks, because moving around in space is really challenging for them.
Besides space exploration, BCI technology can also bring great help to disabled people. For instance, those who have lost their hands or arms may use BCI to send messages or browse (浏览) the internet easily. What’s more, BCI might be widely used in smart homes someday. You could just think “turn on the light”, and the lights in your house would turn on automatically.
()1. What did the students from Tianjin University achieve with BCI technology?
A. They made a magic hat that can help people type fast.
B. They used it to make a robotic arm write the character “fu”.
C. They helped astronauts finish difficult tasks in space.
D. They invented a thing that can collect brain signals.
()2. What is the right order of the process of “mind-writing” “fu”?
a. The robotic arm writes “fu” on red paper.
b. Researchers wear caps with sensors and focus on a screen.
c. A computer reads and analyzes brainwave signals.
d. The computer sends orders to the robotic arm.
A. b-c-d-a B. b-d-c-a
C. c-b-d-a D. c-d-b-a
()3. What does the underlined word “them” refer to in paragraph 3?
A. BCI systems B. tasks
C. scientists D. astronauts
()4. What can BCI technology be used for according to the text?
a. Helping disabled people.
b. Controlling others.
c. Exploring space.
d. Freeing people’s hands.
e. Reading others’ minds.
A. a, b, c B. a, c, d
C. b, c, e D. c, d, e
5. What does the writer mainly want to tell us?

1. B
2. A 由第二段第二至第五句可知，流程为：研究人员戴传感器帽子并注视屏幕→电脑读取分析脑波信号→电脑向机械臂发送指令→机械臂写“福”字，故选A。
3. D 4. B
5. The writer mainly wants to tell us what BCI technology is and its uses.

【分析】
本题为科普类阅读理解，涵盖细节理解、事件顺序排列、词义猜测、主旨大意四类题型。解题思路：1. 细节理解题需定位原文对应段落，匹配选项与原文信息；2. 事件顺序题需梳理原文描述的动作先后逻辑；3. 词义猜测题需结合上下文指代关系判断；4. 主旨大意题需提炼全文核心内容，避免片面信息。
【解析】
1. 定位第一段，天津大学学生用BCI技术让机械臂写“福”字，对应选项B；A选项“魔法帽”未提及，C是未来应用，D是部分环节非成果，故选B。
2. 定位第二段流程：先戴传感器帽注视屏幕（b）→电脑分析脑波信号（c）→电脑发指令给机械臂（d）→机械臂写“福”（a），顺序为b-c-d-a，选A。
3. 第三段提到“astronauts can use BCI to finish difficult tasks, because moving around in space is really challenging for them”，them指代前面的astronauts，选D。
4. 第三段提到BCI用于太空探索（c），第四段提到帮助残疾人（a）、解放双手（d，无需握笔打字），对应a、c、d，选B；b“控制他人”、e“读心”未提及，排除。
5. 全文先介绍BCI技术的应用成果，再讲其在太空、残疾人、智能家居等领域的用途，主旨是介绍BCI技术及其用途，故答案为The writer mainly wants to tell us what BCI technology is and its uses.
【答案】
1.B 2.A 3.D 4.B 5.The writer mainly wants to tell us what BCI technology is and its uses.
