[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: I work so hard that I do not have the energy to exercise .
Person2:That is just an excuse . You can always find some time to exercise .
Person1: But I work hard all the time for long hours . Often I have no time for lunch . Yet , I am still getting fatter .
Person2:Bill , you know that work is not the same as exercise as it is stressful but not relaxing . And skipping meals will not help you lose weight . In fact your body will only store fat if you miss meals .
Person1: I know you're right , but what can I do ?
Person2:How about going for a walk instead of sitting on the sofa reading the newspaper after dinner every night ?
Person1: But I'll miss the news . It's important in my business to keep up with events in China .
Person2:I know , I know . Have you got a portable radio ? You can listen to the news and get healthy at the same time .
Person1: That's a good idea !
