What's the difference between "hear" and "listen"?
1. We "hear" a lot of things, whether we want to or not. 2. When we "listen," we do it on purpose.
Examples: 1a. I hear the dog barking next door. 1b. I hear the telephone when it rings.
2a. I listen carefully when my mother speaks. 2b. Many ESL students need to improve their "listening" skills, but they don't want to take a class in "listening"!
