M: Today time has gone by so quickly! Do you estimate how long a job will take?
W: Well, sometimes it’s not productive for me to estimate how much time I will spend completing a job.

W: If I have an appointment, I try to figure it out how much travel time is involved.
M: I find it really difficult to stay on a time plan when I go to a convention.
W: Why is that?
M: Because I meet so many new people, and I want to interact with them.
W: A convention is a good place to enquire with them professionally.
M: Yes, although I can communicate with many of my colleagues through email, I would prefer to chat with them faceltofface.
W: That would fulfill my needs better because I wouldn’t have to write out my questions or comments.
M: Well, by the way I have noticed that many people in China travel to work by bicycle.
W: Yes, it’s convenient most of the time because the traffic is often very bad.
M: But it would not be possible for me to ride to work in the United States by bicycle because I live a long way from work.

M: In my city in the United States, you have to telephone a taxi if you need one.
