These days, we still need to wear masks because of COVID-19 when we go to some places like hospitals and supermarkets. It becomes a rule. We use lots of masks every day. But do you know a lot of them may end up on the streets, in the parks, or even in the rivers?     1     这对我们的环境是有害的。

A company in Cornwall, Britain came up with a good idea to solve the problem.

    2     他们能把用过的口罩变成有用的东西。 First, they collect used masks. Then, they remove the straps and wires.     3     After that, they put masks into a special machine. The masks turn into big blocks. At last, they break these blocks into small pieces and make litter pickers (捡拾器) with the pieces.     4     It is said that every 45 masks can make one litter picker.

Now in Cornwall, over 300 schools get these litter pickers.     5     Students can use them to help clean up their streets and parks. “The picker is made from masks. Now I can pick up a used mask with it. I think it’s really cool,” says a schoolgirl.
