Have you ever heard the phrase "You never get a second chance to make a first impression(印象)"？ It may sound like an unusual piece of advice，but it is true－the first impression someone has about you when meeting you for the first time will probably influence how that person treats you or reacts to you in the future.
What is even more interesting is that the brain takes in all the information to create that first impression in about three seconds.When you meet someone for the first time，by the time you have stated your name or shaken hands，the other person has already formed an opinion about the kind of person you are.
So how do you make a good first impression？All things grown up tell you such as being polite，and being welldressed are very important.However，the most important tool for making a good first impression is your face.
Smiling，being responsive，and looking like you are happy will almost always leave a positive(积极的)impression on people，especially those who do not know you.Most people，generally speaking，are ready to smile back when they are smiled at.
Furthermore，smiling and being in a positive mood helps you to know and get a better understanding of new things.This means that you can possibly be friendlier to people you do not know and be more creative and able to solve problems more quickly.So if you ever need a reason to be happy，think about the wonderful people you might meet and impress with a cheerful smile.
