Person2: everything's great . I've just returned from my office .
Person1: your office ? Aren't you a freelancer ?
Person2: sure I am . I work for myself , but I've rented a virtual office at an office building in the downtown area .
Person1: a virtual office ?
Person2: yeah , an office that runs efficiently by using nothing other than online communication technologies . I pay the rent and share office services with others in the same building .
Person1: what kind of services do they offer ?
Person2: a separated office , internet access , phone services , fax services , mail & courier services , and almost everything you have in a conventional office .
Person1: sounds fun.what else ?
Person2: I get a business address at an expensive location , and I can share the receptionist and secretary with other offices in the same floor .
Person1: oh , that helps a lot to promote your corporate image .
Person2: you bet it !

[EX Q]: Person1: Did you set your clock forward for daylight savings time ?
Person2: What ? Why do we have to do that ?
Person1: Well , at the start of the spring we usually have more daylight in the mornings and less in the afternoon . This is basically due to our position on the planet and the rotation of the earth . In any case , to take better advantage of the daylight available , we compensate by moving our clocks forward one hour .
Person2: I see . That ' s convenient ! I never understood things like this , such as GMT . I never know what time zone we are in or when to change my clock !
Person1: That just stands for Greenwich Mean Time . Here in California , we are in Pacific Standard Time , that is eight time zones west of Greenwich . Remember when we were in Beijing ? Well , then we were in China Standard Time , and that ' s eight time zones east of Greenwich !
Person2: That ' s why it was so weird traveling from Beijing to LA ! Because of the huge time difference , even though we left Beijing at noon and flew for more than eight hours , we still arrived in LA the same day at noon ! It ' s like we went back in time !
