【简答题】
Listen and practice the following conversation: Can I borrow your phone? Jenny: Can I borrow your phone to call my boss? Richard: I can't believe you still don't have a cell phone. Here you go. Jenny: Thanks. Now, what do I need to do? Richard: First of all, be sure to turn it on. And don't forget to dial the area code. Jenny: OK, I can see the number, but I can't hear anything. Richard: That's because you haven't pressed the “call” button. Jenny: Oh, good. It's ringing. Richard: Try not to get too excited. You'll probably get his voice mail. Jenny: You're right. It's a recording. Richard: Make sure to hit the “end" button or else you'll leave our conversation on his voice mail!
