1 . Only humans speak using words. But all animals can communicate in one way or another. Maybe you have heard about the way bees dance around to send messages to each other and the way dogs make loud noises in different ways to give warnings.

Do you know that animals can communicate through infrasonic (次声的) sounds? This is how it works:

Humans hear low sounds like thunder rumbling (雷声轰鸣) in the sky. But we don’t hear sounds lower than these. However, elephants can hear many lower sounds, and they use them to communicate with each other. This is known as infrasound.

Another surprising thing about infrasound is that it travels over several kilometres. Sounds which have a higher pitch(音调), like the ones people can hear, don’t travel through walls, leaves, trees and so on. And that is why we can’t hear sounds from more than 100 metres away. But infrasound is much ‘stronger’, and things like grass and trees have no effect on it. Because of that it can travel much farther. Elephants can hear infrasonic calls from four kilometres away!

There have been reports that people were watching elephants feeding or resting when the elephants all ran away for no reason at all. It is clear that they heard a warning call from a long way away, but the people didn’t hear the sound. In places like a zoo where you can get nearer to animals, it is a bit easier to sense when infrasonic sounds are made. When you stand near mother elephants with their babies in a zoo you may notice a weak rumbling in the air every few minutes — not loud or strong, but clearly noticeable. They are infrasonic calls — the mother elephants “talking” to their babies.

8 . It’s the end of August, and it’s time to start thinking about going back to school. For some, it’s a very exciting time. For others, however, they can feel very stressful. There are lots of things to do if you want to have a great first day at school.

Stay busy throughout the summer holiday. Usually those who struggle (挣扎) on their first days are people who spend too much of their summer holiday indoors and relaxing. So you should try to stay active and busy over the course of the holiday. There are lots of things you can do, such as getting a summer job or taking up a sport.

Continue learning over the summer holiday. People who struggle the most at first are those who aren’t learning over the holiday. Learning itself doesn’t have to be boring! You can learn about anything you want. Simply keeping your brain in the habit of learning will give you an extra advantage when it’s time to go back to school.

Spend time with friends that will attend the same school. If you have any friends living in the same neighborhood, there are chances that you will go to the same school! Make a point of creating stronger bonds (关系) with those friends. Spend part of your summer holiday with them, and grow closer. While there’s always some worry about going into the first day of school, having friends around that care about you makes it much easier.

Buy your school supplies. The most important thing you can do in preparation for your first day is make sure you have all of the equipment you need. Though the types of materials you’ll need differ from class to class, certain things, like pens and paper, will be used for all classes.
