[EX 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 .

[EX Q]: Person1: What ' s wrong with you ? Why are you scratching so much ?

Person1: Let me have a look . Whoa ! Get away from me !
Person2:What ' s wrong ?
Person1: I think you have chicken pox ! You are contagious ! Get away ! Don ' t breathe on me !
Person2:Maybe it ' s just a rash or an allergy ! We can ' t be sure until I see a doctor .
Person1: Well in the meantime you are a biohazard ! I didn ' t get it when I was a kid and I ' Ve heard that you can even die if you get it as an adult !
Person2:Are you serious ? You always blow things out of proportion . In any case , I think I ' ll go take an oatmeal bath .
