题目
Bill Gates is one of the world's richest men.He and his company,Microsoft,helped make computers cheap and popular.So what's he interested in now？Toilets.
You might not think much about what happens after you use the toilet,but it's important.In I much of the world,toilets are connected to sewers which take human waste and water away.The waste is then removed and the water is cleaned.
But what if you didn't have a toilet？Or what if your toilet wasn't connected to running water？That's the way it is for almost half the people in the world.It's not just smelly.It's dangerous.Without running water,there's nothing to take the waste away.It's hard to keep things clean and healthy.Human waste has many dangerous germs that can make people sick.Around 500，000 children under five die every year because of bad sanitation （卫生系统）.
In 2011，Bill Gates created the "Reinvent the Toilet Challenge".He wanted people to invent toilets that could work without running water.The Gates Foundation gave ＄200 million to work on this problem.
In November 2019，Bill Gates held a special meeting in Beijing,showing off about 20 new kinds of toilets.These toilets can work in places with no running water.Most of the toilets separate and treat the waste to create clean drinking water.The new toilets usually burn the solid parts of the waste.Some are able to create electricity.Others make a fertilizer （肥料） which can help farmers.
Right now,the toilets cost a lot of money.Bill Gates said that the new challenge is learning how to make the toilets cheap enough so that everyone can have a safe,healthy toilet to use.
