While most people are learning to sort(分类) rubbish, a student in Hangzhou does something
46 (much) than that—he designed a smart bin by
47 (he).
Jiang Haotian is a
48 (teenage). His smart bin is made up of two small bins, each with a cover on its top to open or close. The bin can follow
49 (people) instructions. For example, when people say "recyclable waste(可回收垃圾)" or "unrecyclable waste", the
50 (correctly) one of the two small bins will open. When it's full of rubbish, the bin will not open. In this way, it won't smell terrible like the old
51 (one) on the streets. Also, it will make a loud sound when someone throws burning(燃烧的) things in it.
Jiang came up with the idea of
52 (make) a smart bin to sort rubbish when he was in Grade 5. One day, he took out the rubbish and was told not
53 (mix) all kinds of rubbish together. And he started to design it after he
54 (take) a course which taught him to program(编程).
To make the dustbin as perfect as possible, Jiang wrote lots of codes(代码). And he visited different places and asked for advice. After hard work, now his bin works
55 (perfect). It's really useful for the environment!
