What's the Difference Between a Vowel and a Consonant?
In pronunciation, a consonant touches at some point in the mouth. Try saying [p] with your mouth open—you can't do it because your lips must come together to make the [p] sound. A vowel, on the other hand, doesn't touch anywhere. You can easily say [e] without any part of the mouth, tongue, or lips coming into contact with any other part. This is why we are calling W, Y, and R semivowels, or glides.内容来自 听力课堂网：http://www.tingclass.net/show-8155-235200-1.html
