Self-driving cars don’t need people to drive them. They can “see” the road by themselves. Have you wondered how that works?
A school in Jiangsu Province has an answer. It even lets students make their own self-driving cars! Suzhou Science and Technology Town Foreign Language School has a special lab. Students go there for their smart transportation class. In the class, they look at car models carefully. “This helps students better understand the different car parts,” said IT teacher Guo Shuang.
After that, students learn to code. They write programs to make their cars move and do different tasks. The class is very fun. “Our teacher always lets us learn by doing,” said 15-year-old Zhang Xiaoxi. “Each step makes me proud of what I can do.”
But it’s not always easy to make the cars run well. Sometimes, they get “lost”. In one class, students
tried to make their cars follow a white line. “Sometimes the sensor (传感器) wasn’t sensitive (灵敏的) enough for the car to turn in time. Other times, it was too sensitive and the car moved left and right,” said 14-year-old Xue Hongsheng. “But I felt very proud when I finally made it work.”
()36. What do students do first in the smart transportation class?
A. Learn to code. B. Study car models.
C. Drive real cars. D. Fix the sensors.
()37. In the passage, sometimes the cars get “lost”. This probably means the cars .
A. are stolen B. become very dirty
C. go too fast D. cannot find the way
()38. From Xue Hongsheng’s story, we can learn that .
A. making the cars work is always easy B. the teacher will do it for you
C. you need to try many times to succeed D. the sensor never has problems
()39. Why does Zhang Xiaoxi like the class?
A. Because there is no homework. B. Because the teacher lets them learn by doing.
C. Because they can play games all day. D. Because the cars always work perfectly.
()40. What is the main idea of this passage?
A. A fun class for students to make self-driving cars.
B. Self-driving cars are better than our common cars.
C. Learning to code is the most important subject for students.
D. Students in Jiangsu Province are very good at driving cars.

36. B 根据“In the class, they look at car models carefully.”可知,学生在智能交通课上首先仔细研究汽车模型。故选B。
37. D 根据“Sometimes the sensor wasn’t sensitive enough for the car to turn in time. Other times, it was too sensitive and the car moved left and right...”及结合前文汽车“迷路”的描述可知,get “lost”在此处指汽车因传感器问题无法正确循迹,即“找不到路”。故选D。
38. C 根据Sometimes the sensor wasn’t sensitive enough及“But I felt very proud when I finally made it work.”可知,他们最后成功了,这体现出成功需要多次尝试。故选C。
39. B 根据Our teacher always lets us learn by doing可知,她喜欢这门课是因为老师让他们通过实践来学习。故选B。
40. A 全文围绕学校开设的智能交通课程展开,重点描述了学生制作自动驾驶汽车的过程、挑战和收获,强调了课程的趣味性和实践性。因此,文章主旨是介绍一门让学生制作自动驾驶汽车的有趣课程。故选A。
