[EX Q]: Person1: Wake up sleepyhead.The sun is beginning to shine . What a lovely summer day !
Person2:Yeah , clearly blue sky.But it is a bit too hot for me . I don't like heat and humidity .
Person1: It's not that hot . It's cooler than yesterday . Let's go swimming !
Person2:That's a thought . It's still early , and the beach isn't crowded at this time of the day . If we don't stay too long , we won't get sunburned .
Person1: Yeah , sounds like fun . I can wear my new pink bikini .
Person2:There won't be anyone there to appreciate how cute you are .
Person1: Who cares ! Well , the smart guys get there early . That's the kind of guy I want to meet . Let's go !
Person2:If you are going to husband hunting in a bikini , then I want to wear one , too .
Person1: Ok , you could borrow one of mine .
Person2:Thanks , how about the green and black one ?
Person1: No problem . Here it is .

[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 .
[EX A]: formal
