[EX Q]: Person1: Did you hear about car accident on Spring Road yesterday ?
Person2:Yes , I did . I heard that they took both drivers to hospital . One needed surgery .
Person1: Yes . I heard he had a few broken bones too , but that the doctors have set the fractures without any problems .
Person2:The second driver was luckier . He had a concussion and needed some stitches for his head wound .
Person1: Yes . He was released from hospital yesterday evening . The other man could be there for weeks .
Person2:I understand that he ' s connected to a heart monitor and breathing apparatus . His condition can ' t be very good .
Person1: The hospital announced this morning that his condition is poor but stable . What does that mean ?
Person2:It means he ' s really badly injured , but he will almost certainly survive .
Person1: His family will be pleased to hear that . They must have been so worried .

[EX Q]: Person1: So , is L . A . all it's cracked up to be ?
Person2:Well , the stereotype in the movies is that L . A . is a frivolous town with a lot of flaky people . I guess , in the back of my mind , that's what I expected .
Person1: And , is it what you found ?
Person2:Well , it is and it's not . The city of L . A . is much bigger and more diverse than I had expected . There are people here from all over the country and all over world , like New York . I've heard people say that in L . A . , everyone is from somewhere else . Tha's partly true . So , I've met all kinds of people here . What I'm realizing is that the picture of L . A . that's in movies only represents a small segment of the city .
Person1: You're right . Life isn't always like the movies .
