Hello, everyone! I’m Callie of St Julie Billiart, a nine-year-old boy. As you know, a big problem in the world today is the loss of energy. One way of energy loss is when people brush their teeth, they leave the water running. This wastes one of the world’s best resources—water.

To solve this problem, I have made a machine that controls how long the water can run in your tap（水龙头）. This machine has a set of buttons（按钮）on it. On each of the buttons there is a word, for example “wash hands”. My machine will turn the water on for a certain time, and then automatically（自动地）turn off. It is called the Automatic Water Turn-er Off-er.

This machine is not too hard to work. There are no handles（把手）to turn, which prevents people from using it when they don’t want to use the buttons. I hope that this machine will solve our problem of water loss.

The Automatic Water Turn-er Off-er will cost about $250.00 to deliver and install（安装）. This machine will help people who don’t know how long they should wash their hands or how long to brush their teeth. Both doctors and dentists will like it.

If you are interested in my invention, please reach my teacher Jean Stringer or me. Thanks for listening to my speech.

A new font(字体) designed by a Finnish software company could make your writing more polite and hopefully reduce cyberbullying(网络暴力).

Polite Type, developed by TietoEVRY, replaces harmful language with nicer words as you type. For example, if you type “you are ugly”, it will be replaced with “you are not traditionally beautiful”.

“We want bullies(欺凌者) to rethink the words they use and the actual meaning behind them,” said company manager Kia Haring.

The problem of cyberbullying has been around since the internet was invented. Nearly everyone who has used the internet has experienced it, or at least seen it in action.

Polite Type is a good step in the right direction. But how do we really deal with cyberbullying? For one, we can choose to be “invisible (隐形的)”—that is, to surf the internet without making any profiles (个人资料) or leaving any comments(评论). This, however, isn’t a real solution, as it forces us to give up our right to “exist (存在)” online.

We can also choose to simply take no notice of bullies. However, this isn’t perfect either, as it can be hard to forget people who are especially cruel (残酷的).

A better solution could be to block and report. If you block someone on social media, they won’t be able to see or comment on your posts. Most websites have rules against harmful language if you report a bully’s profile to the website, they will often stop that person from using the website. Sometimes direct action like this is the best action to take.
