    Researchers have discovered that, in general, it only takes seven seconds for a person to start making judgments about you when they first meet you. That's why you should follow these useful tips on how to create a good first impression.

    Before meeting someone, start thinking about the purpose of the meeting. Are you trying to impress them? For example, if you want to make new friends at a social event, you will want to appear friendly. And if you decide to run for class president at your school, you will need to appear confident（自信）.

    Smiling is the most important thing you can do when meeting someone new. It shows that you're friendly and makes people around you feel more comfortable. To have a winning smile, make sure your teeth are clean by brushing them every day.

    Before you begin speaking, you will be judged on your body language. Therefore, it's important to show trust in yourself by standing up tall and putting your shoulders back. Besides, if you uncross your arms, you will appear relaxed and friendly.

    How you smell can influence people's first impression of you. If you have a bad body smell, it will put people off. In short, aim to smell clean and avoid putting on a lot of scented products.

    What you wear matters. While you should look clean and tidy, it's also important to dress properly, whether you're going to a birthday party or a sporting event. You should think about what your clothes say about you.

A. Smell good B. Dress to impress C. Get ready for a speech D. A smile goes a long way E. Be careful about your body language F. Decide what image（形象）you want to present
