Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobile phones are usually to blame* for a number of things: from headaches to house fires. One theory even blames mobile phones for the disappearance* of bees!
The theory is that the bees’ navigation systems are damaged by the radiation* from mobile phones. Bees have a built-in system, and this helps them find their way back to their hives*. But recently, thousands of bees have failed to find their way home.
The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems. The important thing about bees is that most of the plants in many countries of the world are pollinated* by them. Without bees, the plants can’t grow. Many beekeepers in America and Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, a London beekeeper, was recently asked how the problem was affecting him. “My business has been destroyed by this,” he complained.
Nobody has proved that this theory is true but it’s a fact that bees are disappearing in very large numbers. And we can do nothing without them. Einstein said that if all our bees disappeared, man would only live for four more years! The situation firstly needs to be tested by the world’s best scientists. If the result proves that the theory is correct, we need to do something about it immediately — before it is too late.

【推荐2】Trees are one of the oldest “citizens” of our Earth. Trees keep our air clean, reduce noise pollution and provide food. Just like us, trees change a lot as they grow. Between 1 and 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns（刺）to make animals not go near.
At the age of 15, trees become young adults. They begin to produce flowers and fruit.
It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. The adult tree not only gives us shade, oxygen and natural beauty, but also provides a great place for us to rest, read books or listen to music. After that, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When part of a tree becomes dead, it provides a home for small animals.
In many ways, the life of a tree is just like everyone’s own life. Each period of life brings its own joy and challenge. Enjoy every minute of the life of the trees and take care of trees.

【推荐3】Winter is hard for most animals. So some birds and animals fly to the south.
The groundhog (土拨鼠), however, deals with winter differently. As soon as it feels the weather turning cold, it starts to dig a hole at least five feet underground. There it makes a comfortable home with leaves and grass. It spends the cold winter months in its underground bed and it won’t wake up until spring.
The groundhog doesn’t eat at all during the winter. Instead, it eats as much and as often as it can during the summer. As winter comes, the groundhog becomes so fat that it can hardly move. When it starts to feel sleepy, it goes back to the home and falls into a deep sleep. Its breathing almost stops, its heart slows to about four beats a minute and its body temperature falls to just above 0℃ during the sleep. When it wakes up in spring, its weight (重量) is only half of what it was in the fall. By February or March, it’s ready to leave its hole.
So years ago, when science and technology was less developed, people often waited for the first groundhog to stick its head out above ground as it showed that spring was coming. This gave rise to a number of stories. One of them is about a groundhog called Phil. This animal could forecast (预测) the weather. Phil stuck his head out above ground and looked around every February 2nd. If he saw his shadow (影子), it meant that there would be an extended (延长的) winter of six weeks. If the weather was cloudy and he didn’t see his shadow, it meant spring would be early.

100 Easy Science Experiments for Kids to do at Home （2023） |
Do you have a little scientist living in the house with you? You’re probably looking for science experiments for your kids at home. |
We searched the Internet and practiced these science experiments with our own young kids. They’re super educational and so much fun for kids of all ages! Each of these easy science experiments will take only about 30 minutes to complete from start to finish. They each use simple materials from around the house. And, they teach simple science knowledge that your kids will use in school. It’s also a great way to learn about the scientific method that they’ll use throughout their whole life. Here is a fun science experiment to introduce your child to the magical world of science! |
Water Cycle In A Bag This is one of the best science experiments to teach your kids about the water cycle, and it’s so easy to do! |
| Materials (材料): Zip (拉链) lock bag, marker pen, water, blue food coloring |
| Steps: ◆Use a marker pen to draw a sky on the upper half of your Zip lock bag. Include clouds and the sun. ◆Fill a cup with water and add a few drops of blue food coloring. Mix it up until the water is blue. ◆Pour the water into the bag and zip it tight, so no water escapes. ◆Hang your bag up on a window that gets a lot of sunshine. In a couple of hours, you will see some drops of water will be in the “clouds” and other drops will be coming down like rain. |
What’s Happening? The sun is heating up the water in the bag, which turns the water into the gas. This happens in our atmosphere, too. Because the water is in a bag and has nowhere to go, it turns back into water. This experiment shows the power of the sun to turn water into different states.

【推荐3】I’m the engine that keeps you working, and I’m here to share some of my secrets. I have 100 billion nerve cells(神经细胞), so you need to consider before you blame(责怪) me for not being so fast enough. It’s not really my fault: information travels through me too fast and sometimes I can’t keep all of it.
The Internet is making me weak. A study found that you’ve been relying more on the Internet. That means I’m going to forget more over time. Scientists have been worried that our ability to think is being lost.
In general, I’m about ten percent larger in men than women. It doesn’t make men smarter. It just lets me control their different bodies. Actually, it’s more common for women to get angry, but men can’t focus on a thing well. They usually have language difficulties.
Your mobile phone scares me. A new study showed that more than one hour of mobile phone use can get me in trouble. Mobile phone radiation(辐射) might cause me to be in a worse situation.
Some parts of me never sleep. It’s important for you to get a good night’s sleep. Sleep helps to improve memories. In fact, when you are asleep, some parts of me are still working hard on my duty. Besides, laughter is really the best medicine for me. So remember to laugh more for my better situation.
