[新素材]素材话题:突破障碍的出行新发明
[2026 吉林长春期末]Going up and down stairs is really difficult for people in a wheelchair. But a new invention may change that. A group of scientists have invented a special wheel. 4 The wheel has a sensor (传感器), an outer circle of chain and a set of wires. The wires run through the centre of the wheel. 5 This allows the wheels to change shape and roll over the barrier (障碍物). The wheels can go over a barrier up to 1.3 times the height of their radius (半径). They can then change back to hard wheels for faster travel on flat ground.
6 They made the wheelchair climb the stairs with a life-size dummy (真人大小的人体模型) in it. Each step was 18 centimetres tall. The wheelchair easily did that.
On flat ground, the wheels can run at speeds of up to 30 kilometres per hour. The scientists are working on making them go even faster. 7 That is the medium speed of cars on the highway.
The team believes that their wheels will be very helpful in the future. With the wheels, a robotic delivery vehicle (运送车) could climb stairs to deliver food and more. The wheels could also be used on two-legged and four-legged robots. 8 These robots could work in factories or even dangerous places like battlefields.
A. The team tested the wheels on a wheelchair.
B. It can change its shape to move over barriers.
C. Their goal is to reach about 100 kilometres per hour.
D. When the sensor meets a barrier, it softens the wires.
E. They would help the robots move more stably and reach more places.

4. B 根据前文及“The wheel has a sensor, an outer circle of chain and a set of wires.”可知,此处总述轮子的特点,选项B(它可以改变其形状以越过障碍物。)符合语境,故选B项。
5. D 根据“The wheel has a sensor... The wires run through the centre of the wheel.”和“This allows the wheels to change shape and roll over the barrier.”可知,此处应介绍这些部件的作用,选项D(传感器遇到障碍物时,它会软化电线。)符合语境,故选D项。
6. A 根据“They made the wheelchair climb the stairs with a life-size dummy in it.”可知,此处应介绍在轮椅上测试轮子,选项A(该团队在轮椅上测试了轮子。)符合语境,故选A项。
7. C 根据“The scientists are working on making them go even faster.”和“That is the medium speed of cars on the highway.”可知,此处应介绍轮椅会达到的速度,选项C(他们的目标是达到每小时约100千米。)符合语境,故选C项。
8. E 根据“The wheels could also be used on two-legged and four-legged robots.”和“These robots could work in factories or even dangerous places like battlefields.”可知,此处应介绍轮子在机器人上可能的应用,选项E(它们将帮助机器人更稳定地移动,到达更多的地方。)符合语境,故选E项。

新素材素材话题:采茶新发明——龙井茶园的机器人
[2026 湖南长沙期末]Spring is coming, and it's time to enjoy the West Lake Longjing tea! Usually, we think workers will pick tea leaves by hand. But now, some Longjing tea leaves are being picked by special workers—tea-picking robots!
In a tea garden in Hangzhou, a smart tea-picking robot invented by Zhejiang Sci-Tech University is working for the first time. "We take thousands of pictures of new tea buds (芽) and make the robot learn them carefully. The robot uses an AI model to find the buds that it should pick," said Professor Chen Jianneng, a member of the research team. This helps the robot find the right tea buds most of the time.
The robot's arm pulls and then sucks (吸) up the tea buds. These buds are quickly moved into a special box. Once the robot has collected all the buds from the area it's working at, it moves the buds from the box to a main box that holds everything it collects.
The robot was made because there are not enough people to pick tea. In Zhejiang, about 2,000,000 pickers are needed now. "Picking is the biggest challenge for the development of the tea industry," said Professor Wu Chuanyu, who leads the research team.
"Tea-picking robots are a trend (趋势) of the future," said Wu. "About five years from now, the robots will do the job of picking the West Lake Longjing tea instead of people," Wu added.
9. How are tea leaves usually picked?

10. To find tea buds, what is the robot made to learn carefully?

11. How does the robot pick tea buds?

12. How many pickers are needed in Zhejiang?

13. What do you think of the tea-picking robot?

9. They are usually picked by hand. 根据第一段的“Usually, we think workers will pick tea leaves by hand.”可知,人们通常手工采茶。
10. Thousands of pictures of new tea buds. 根据第二段的“We take thousands of pictures of new tea buds and make the robot learn them carefully.”可知,机器人通过仔细学习数千张新茶芽的图片来识别茶芽。
11. The robot's arm pulls and then sucks up the tea buds. 根据第三段第一句可知答案。
12. About 2,000,000. 根据第四段的“In Zhejiang, about 2,000,000 pickers are needed now.”可知,浙江目前需要大约200万名采茶工。
13. It's very helpful./... 开放性试题,言之有理且无语法错误即可。
