Florida teen band The Garbage-Men is performing on the stage. The band has five members. They are Jack Berry, Ollie Gray, Harrison Paparatto, Austin Siegel and Evan Tucker. The five teens are making music from waste. The Garbage-Men band's instruments are made from recycled things. The guitars are boxes. A horn(号) is made from pipes. The keyboard is formed from old bottles.

    The band started about two years ago. Jack Berry who was in eighth grade at the time decided to make a playable, home-made guitar. After some trial-and-error(反复试验),                he ended up building it from a cereal box,  a yardstick and toothpicks. After Jack showed his creation to his friend Ollie Gray, Ollie had the idea to form a band using other home-made instruments as a way to improve recycling. “We want to show people there is more to recycling than throwing things away in the bin.” Jack, 16, told TFK. “You can actually reuse materials.”

Last year, the Garbage-Men played at local events, including festivals, farmer's markets. Typically， the teens set up on the street and performed popular songs from the 1960s， including classic Beatles and crowd favorite “Wipe Out”. They talked about recycling and offered tips for how to improve the environment. While they were performing, Jack's little brother Trent, 11, gave out leaflets about recycling and helped sell the band's CDs and other musical products.

The band donated the money from sales to charity. They have raised more than $2,500 for Heifer International. The organization gives farm animals, seeds and agricultural training to people in poor countries to help end poverty and hunger. “It's a good, sustainable-development (持续发展的)charity,” Jack says, “By donating one animal, you help the whole community.”

The band, all tenth graders, tries to play a show every week. They've also played on a Florida radio station. The teens hope to take their shows on the road by touring in other states. “Music is a really good way to get a good message across to people because it's really close.” Jack says. Their instruments may be rubbish, but their message isn't.

    There are many kinds of ants(蚂蚁) in America. One is very strong. People are afraid(害怕) of it and animals are afraid of it, too.

    These ants are often in big groups(群). They eat all the animals on their way. They can kill(杀死) and eat elephants. And they can eat house. Sometimes they can kill people and eat them. When the ants come near, people leave their homes. But people are sometimes happy after the ants pass by (经过), because they can see no insects(昆虫) or snakes(蛇).

    Have you ever wished that your life was like a reality TV show(真人秀节目)? Well, like it or not, things might be this way in the future.

    This is because of Google glasses. Glasses are the latest technology from Google. They have more exciting features(特征)than you could possibly imagine.

    For one thing, people who wear the glasses can shoot videos and record the sounds around them. So if your friend is wearing Google glasses, he or she can record your every move and broadcast live on the Internet for the world to see.

    There is a GPS system in the glasses. So if you get lost you can say" OK, Glass, where am I?", and it will find where you are and tell you where you need to 90.

    Google glasses are a bit like a helpful secretary. You can tell them what you want to write in an e—mail and they will type it for you.

    Since April 16, Google glasses have been on the market in small numbers. But by the end of the year anyone will be able to buy a pair for about 2, 500 yuan.

    Some people are not sure whether they find Google glasses cool or not. When someone is wearing Google glasses, it is not easy to see whether or not they are using them.

    A myth is something that is not correct, but many people believe. There are a lot of myths about the human brain.

    One of the biggest myths is that we only use 10 percent of our brains. The next part of the myth is that if we can learn to use the rest of our brains, then we'll be much smarter. People say this all the time, but it's absolutely not true! The truth is that although we don't know everything about the human brain, we know that each part of it has an important function (功能). Modern scientists think the "10 percent myth" ridiculous(荒谬的).

    The other most popular myth is about being "right brained" or "left brained". According to this myth, people who use the right side of their brains are more artistic and creative. People who use the left side of their brains are better at math and science. This is as popular as the 10 percent myth, and it's also wrong. In 2013, a study at an American university examined the right brain and left brain myth. According to the study, we use both sides of our brains equally (相等地).

    It's true that we use different parts of our brains for different things. We use our left side for language more, and our right side when we need to pay attention. But there is no evidence (证据) that creative people use the right side more, or that scientific people use the left side more.

    We've talked about myths, so let's look at a few interesting facts about the brain. First of all, the brain feels no pain. Second, about 75 percent of the brain is made of water. It's also the fattest organ in your body. Here's another interesting fact about the brain. Around the time you turn 18 years old, it stops growing.

    Artificial intelligence(AI)(人工智能)is the ability of a computer program or a machine. The computer or the machine with AI can think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with(提出)the name "artificial intelligence" over 60 years ago. Many things such as learning and problem solving can be done by computers, though not in the same way as people do.

    An unusual goal of AI research is to create computer programs. They can learn, solve problems, and think logically(逻辑地). At present, Al can successfully understanding human speech, recognizie (识别)human faces, operate self-driving cars and compete in some game systems like playing Chess. However, Some people also consider(认为）AI a danger to humans if it develops too quickly. A famous British scientist also was not for this kind of technology.

    Math is the basic language of AI. If students are good at math, they will be more likely to become successful AI designers(设计者)in the future. We need not only bright students, but also average(普通的)students. As for(对于)average students ，if they get enough math skills, they can also become successful AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.

    Scientists hope to create creative(有创造力)and emotional (有感情的)AI. The AI can possibly understand human feelings or create art. Many ways and tools have been tried to discover this wide and exciting field.
