Q: Person1: How do I apply to an American university ?
Person2:You should go to the library to find some information about American universities , and write to the Admission Office . Then the Admission Office will send you application forms and other related materials . From experience , many applicants write to several universities instead of just one .
Person1: I was told that it took a lot of time and effort to apply .
Person2:That is true . I'll list for you the requirements of almost all the universities . First of all , you need official transcripts of your undergraduate work , three letters of recommendation from your professors who know your competence , and the official TOEFL ( Test of English as a Foreign Language ) score ( It's usually 550 ) . Then you need a financial guarantee , and an application fee of 25 dollars .
Person1: What's to come next ?
Person2:If they agree to enroll you , they will send you a TAP - 66 Form . With TAP - 66 , you can apply for a passport from our government , and then apply for a visa from the US Embassy in Beijing .
Person1: How long will it take to go over all the procedures ?
Person2:From 3 to 6 months if everything goes well .
Person1: Thank you . I appreciate all your help .
Person2:You are welcome . Please feel free to ask if you have any more questions .

Q: Person1: What is your favorite coffee ?
Person2:Irish coffee is my favorite . But I'm not particular on it .
Person1: All right . Would you make coffee yourself when you are at home ?
Person2:Not very often . Making coffee is a bit troublesome . Most of the time , I just buy takeout at Starbucks . And also , I quite like instant coffee .
Person1: I think instant coffee is becoming more and more popular . Though its taste is not perfect , it's really cheap and convenient .
Person2:Exactly . Nescafe is the world's favorite coffee . People love it all over the world .
Person1: I agree . I heard that in the western countries , almost everyone likes coffee . Is that true ?
Person2:Yes . No doubt about that . For us , coffee is more a living style rather than a simple drink . I heard Chinese people don't drink that much coffee .
Person1: No , we don't , especially the elder people . But more and more young people fall for coffee nowadays .
Person2:I suppose so . That's probably why there are so many wonderful coffee houses in China now .
