五、思维品质·勇于探究 任务型阅读
Kristen Tapping, a student from London South Bank University, has invented a bike wheel that can help clean the air. It’s called Rolloe.
The wheel uses fins (尾翼) to pull in air as it turns. It then uses filters (过滤器) to take in polluted air and give off clean air back into the environment. The wheel can filter more air if it goes faster, although it still works at low speeds.
Tapping said users would need to change the filters every week or after about 250 kilometres, to make sure the wheel continues to work well. The wheel fits in the front of a standard (标准的) bike and weighs about one kilogram.
Tapping said she was encouraged to create the wheel when she was biking around London. “In traffic, you always notice the pollution, the heat, the gases and the smell,” she said. She predicts that if 10 percent of the riders in London had a Rolloe on their bike, they could filter about 266,865 $ \mathrm{m}^3 $ of air a day, although this has yet to be tested.
Tapping wants to use the wheel on shared bike projects at first, with the aim of making the wheels available for all bikes to use. She says she would also like to create wheels that will fit in the back of bikes, as well as making them available in different sizes.
26. What does the wheel use filters to do?（不超过10个词）
27. Where does the wheel fit?（不超过10个词）
28. What do you think of the wheel?（不超过20个词）
