Let's go get a sandwich, shall we? I'm getting a bit hungry.
This one looks good! Chicken and mayonnaise on multi-grain bread . . . Yum!
I'll have a ham and cheese baguette, I think.
Oh, look at the gelato! I'll get a chocolate gelato as well.
Hey Anne, do you want a cookie?
Sure, let's get a couple. I like the chocolate chip ones.
To make your English sound natural, vary your tones. It is boring to use a flat tone throughout. Intonation is very important when you speak. Add some feelings to it too. Take the above dialogue as an example. Don't just read it aloud with one tone. When you see a question mark, raise your tone because you're asking a question. When you see an exclamation mark, use a heavier tone because the speaker is getting excited about something. Look at the sentence, imagine the scenario and the speaker's feelings and express them with the appropriate tone.
1. Find out what you two have in common.
2. Look at the person while you talk. Eye contact is very important.
3. Be pleasant. A smile goes a long way.
