You have to be careful when throwing away wet rubbish, which may include food or other kinds of rubbish. Maybe these kinds of waste have made a big mess when you've thrown (they) away before.
Shi Yuan, 14, from Shanghai Wenlai Middle School, has made a special plastic bag to solve this problem. plastic bag has a band of adhesive tape (粘贴带). When one end of the tape is open, the bag can (turn) upside-down. You can hold the bottom end and throw wet rubbish into a trash can (easy).
Shi came up with the idea after an unpleasant experience in which he got wet waste all over his pants while throwing it away. He found that many other people had the same problem. He decided to solve this problem and (invent) his special bag.
He first thought about using a gunny (麻布) bag or placing a bag break on his trash cans. But of these ideas worked. So he decided to just design his own rubbish bag. "I didn't want to put any extra burden (负担) on the bag, so I used adhesive tape." Shi said.
, the bag he made first was a one-off product and not environmentally friendly. So Shi kept on improving his design.
He remembered (read) about the adhesive used for Post-it notes (便利贴). Shi thought this weak glue could be used for the adhesive tape and allow the rubbish bag to be reused.
So far, he (sell) 2 million bags online. His bag has become popular in many communities. His father is quite proud of him.
" (child) like to play. Shi just changed the way he 'plays' and put his mind toward looking for a way to make life easier," Shi's father said.
