This old saying comes true in the story of Remya Jose, a 14-year-old girl from India. When Remya’s mother fell ill, she had to wash clothes by hand in the nearby river. She soon found it took too much time and energy. So she decided to create a better way using bicycle parts. Remya’s invention is a pedal-powered(踏板驱动的) washing machine. The machine has a round metal drum held in a strong wooden frame(框架). A thick chain(链条) connects the bicycle pedals to a metal stick that runs through the centre of the drum. When you step on the pedals, the chain pulls the stick, making the drum go around smoothly inside the frame. To use the machine, people first need to put in dirty clothes, soap powder(洗衣粉) and some warm water until the clothes are fully covered. Next, sit on a chair in front of the machine and start stepping on the pedals — slowly at first, then faster. The drum moves the clothes around in the soapy water, making them clean like hand washing. This machine is great for places without electricity. It saves time and helps people stay fit while doing chores. However, success didn’t come easily: sometimes the metal drum fell off, and other times water went out from the drum before cleaning finished. But Remya didn’t give up. She added a special ring to stop water going out and fixed the chain tightly. Finally, her machine worked! Remya even won a prize from India’s president for her creative idea. Just as Remya wrote in her diary: Age is just a number when it comes to invention. ( )1. Which of the following shows Remya’s invention? ( )2.
