Pollution inside homes and other buildings kills more than 4 million people each year. Many people die as a result of breathing smoke or from cooking over wood-powered or coal-powered stoves.
One way to reduce the number of deaths is through cooking equipment powered by the sun. Crosby Menzies, a solar power expert in a South African company, described his latest solar cooker called the ―Sol-4‖. ―It is four square meters of
mirrors, six to eight meters in length. It is quite a large cooker.‖
The ―Sol-4‖ works by reflecting(反射) light from the sun off large mirrors. The
mirrors direct the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.
The cooker is also much ―friendlier‖ than other models becau people do not have to stand in the sun to u it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals would be less likely
to have breathing illness from harmful smoke.

We all know that recycling rubbish is very important. But sometimes it is not so convenient when we can‘t find a recycling bin anywhere.
Now a team of middle school students from the US has solved that problem by designing
their Recycling Bin app (应用程序).
This app encourages people to recycle. It provides urs with a map of local recycling centers. And it allows them to save places as favorites on it. This app
also reminds urs to recycle.
The group of nine sixth-graders is from STEM Center Middle School. They came up with the idea as part of a school project for the Verizon Innovative App Challenge. Their school provided professional app training. It gave 10 teams Samsung tablets (平板) as prizes.
The challenge wanted to develop students‘ interest in science, technology and engineering. In this contest, students showed an app design that could solve a problem in their school or city. The nine students came up with the idea for Recycling Bin when they saw a need for more recycling.
―We thought that this would really help a lot of people,‖ Jaden Hilkemann, 12, told Time
For Kids.
They kept their design easy so that anyone could u it. Now the free Recycling Bin app has been put into u in the Google Play app store for Android phones or tablets.
―I was so excited when it went up at the app store,‖ Seralyn Blake, 12, said. ―A lot of my family members downloaded (下载) the app. It was pretty cool.‖
