本单元是关于Tim 爱的忠告的对话

Michal: Tim, can I talk to you?
Tim: Sure, what's on your mind?
Michal: It's about Helen and her family.
Tim: Yeah, how was that visit you had to her folks' place?
Michal: It was difficult.
Tim: Why?
Michal: Well, I thought Helen and I were just having some fun, you know, nothing too serious. But her parents have already got us married and are right now thinking up names for the grandchildren we're going to give them!
Tim: Does Helen feel the same as you then?
Michal: I'm not sure.
Tim: Well, you need to find out and then you've got to set her parents straight ... I wonder who that is.

Voiced and unvoiced sounds 发音和不发音

If a sound is voiced it means that there is a vibration in your throat when you say the sound. If place your hand over your throat and say the sound /z/ or /m/, for example, you can feel your throat vibrate or buzz. When you say an unvoiced sound, on the other hand, like /s/ or /t/, you can't feel any buzz or vibration in your throat.
