(B)
When Riya was 14, one day, she saw a blind woman walking alone on the street, using a traditional white cane to find her way. But even with the cane, she kept bumping into things. That moment sparked something in Riya. She could not believe that in a world full of smartphones and self-driving cars, blind people were still using simple sticks to get around.
She decided to do something about it. But there was one big challenge: she was
not an engineer and did not have a laboratory. All she had was a computer connected to the internet and a strong desire to help.
Through months of online research and self-learning, Riya designed a “SmartCane”. The device attaches to the bottom of a traditional white cane, and uses sensors to detect obstacles. When an obstacle is detected, the cane vibrates to warn the user.
But Riya didn’t stop there. The SmartCane also connects to a smartphone app that offers voice navigation, telling users when to turn and how far to walk. It can even identify nearby crosswalks and tell users when it is safe to cross.
Riya built her first model cane using a 3D printer at her local library. The total cost was about 150, while other high-tech canes usually cost thousands of dollars.
When she tested the SmartCane with blind users, one of them said, “This is what I’ve been waiting for. It makes me much more independent.”
Riya’s invention has won several national science competitions. She has been invited to speak in public. Now, she is working with a team of engineers to bring the SmartCane to market at an affordable price. “Technology should be for everyone, not just those who can afford it,” Riya said.
If a 14-year-old girl can help solve this problem, imagine what we can all do if we just care a little more.
46. What surprised Riya when she saw the blind woman?
A. Her cane was just a traditional stick without high technology.
B. She was blind but nobody was walking with her in the street.
C. She lived in a world full of smartphones and self-driving cars.
D. Even with the cane, she kept bumping into things.
47. What was Riya’s biggest difficulty when she started her project?
A. She had no computer or internet connection at home.
B. She had no money to buy materials for her invention.
C. She did not know how to use a 3D printer in the library.
D. She wasn’t an engineer and had no laboratory to work in.
48. What is special about the SmartCane?
A. It needs a smartphone in order to work well.
B. It warns users by vibrating and making sound.
C. It costs much more than other high-tech canes.
D. It sells well and gains popularity in the market.
49. What was the blind users’ attitude towards the SmartCane?
A. They were worried whether it would be safe to use it.
B. They were satisfied with it and gave positive response.
C. They were interested and planned to use it every day.
D. They were impatient because they waited too long for it.
50. What does Riya’s story mainly tell us?
A. Scientists should use technology to solve problems.
B. Blind people should be taken good care of by society.
C. A caring heart and a strong will can make a difference.
D. Being an engineer is a great dream that we should pursue.
