As a new student in a school, you will give a talk and introduce yourself in a class. Do you know how to introduce yourself?
Here are some ways to make sure you can let others know about you quickly:
●Start with a smile and be friendly. This will make your classmates more interested in what you say.
●Tell others about your name, age, class, hometown, hobbies, and interests. Talking about your family is also a good idea.
●Speak slowly and clearly, and makeeve contact with your classmates.
●Let others know what you are good at. This may help you make new friends quickly.
●Practice beforehand(预先). If you do so, you will feel better when you introduce yourself.
Hope you can have a great life in a new school.
Have you noticed that time seems to pass more slowly when you're waiting in a long line? But when you're playing with your friends, hours seem like minutes. Of course, time is always passing at the same speed--but why does it sometimes feel different?
A study in the Journal of Neuroscience can tell us the answer. Lead researcher Masamichi Hayashi and his research team in the US have found that it has something to do with neurons (神经元) in our brains that are sensitive(敏感的) to time.
The researchers studied the brain activity of 18 adults who were asked to look at a picture on a screen for a certain length of time. They were then asked to guess how long they'd been looking at the picture. They tended to(倾向于) guess incorrectly in the end when they were asked to stare at the picture for very long or very short periods of time.
After researching into their brain activity further, the researchers discovered neurons that work actively in response to(对…有反应) certain amounts of time, which are called time-sensitive neurons. When they receive repetitive stimulation (重复的刺激)(such as staring at a screen), these neurons finally get "tired" and don't work properly. It doesn't matter whether this amount of time is long or short, as long as the stimulation is repetitive. However, other neurons still work normally, having an influence on the ways we experience time.
When you stand in line or do some other repetitive things, such as math homework, your time-sensitive neurons get tired and cause you to feel like time is going slowly. But when you're doing something more fast-changing, such as playing soccer, you feel like time is flying. Either way, you'd better be careful with your brain when it comes to your experience of time. It may lie.
