Input:  Person1:       So it looks like we start selling in the U . S . next year .  
 Person2:Did Mr . Lin put you in charge of marketing ?  
 Person1:        He's still not sure whether he wants to put me in charge , or whether he wants to hire an American.But even if he hires an American , I'll probably be transferred to our American office .  
 Person2:Where will it be ?  
 Person1:        We aren't sure yet . Maybe L . A . I think L . A . would be the best idea .  
 Person2:Is it because of trade negotiations that we can start selling in the U . S . ?  
 Person1:        Yes , the recent agreements between the two governments have changed everything.Now we have the right to sell in America at a much lower tariff.It ' s going to be good . We can compete more directly with them .  
 Person2:Great .  
 Person1:        Our computers have a high level of quality now.We can demonstrate it . And our prices will be good.So I think it will really be worthwhile .  
 Person2:You seem excited about it .  
 Person1:        Well , you know I studied marketing in America.So maybe the thought of going back there to promote our brand is kind of exciting to me . I'd love to be part of the team .  
 Person2:Do you honestly think we can compete though ? All the computer giants are there .  
 Person1:        Yes , I do . I think we can compete . I think we can make a name for ourselves.It will be hard at first . But if we develop a good advertising campaign , I think we can break into the market .  
 Person2:The company will have to choose a good advertising firm.And then there's the problem of quality.How do we convince American buyers that our quality is good ?  
 Person1:        It takes some time.Because even if the quality is high , people won't accept a high tech product unless they recognize the name.Name recognition is crucial .  
 Person2:Well , I hope it all works out , John . I think if you're part of the team , things will go well.But you know we'd all miss you here . So I won't say I'm happy to think that you're leaving .  
 Person1:        That's very nice of you to say.But if we set up an office there in the States , maybe you could try to become part of it .  
 Person2:Me ? No way . I'm dedicated to the company , but I'm not going to leave Taiwan . I'm happy here .
