跟外教學英語 English Pronunciation: "F" vs. "V" Sounds

My name is Megan Brach, I've been teaching English as a second language for four years. Learning English isn't fast nor is it easy, but I'm gonna help you get started. Are you ready? Let's learn English. Now let's learn the difference between the F and the V sounds. You're going to put your top teeth on your bottom lip and breathe out, but for F you're not going to use your vocal cords. So practice,fine, first, half, fun. Now for V your mouth shape is going to be the same but now you're going to use your vocal cords. So let's practice, vine, very, vivid, valve. So now you practice the difference between your F and your V sounds.
