Просто перевести текст (за ранее спасибо)

Not long ago Vlad applied for a grant from an American university.

He was sure he had all chances to win this grant. Soon he got a message that the

board at the University had sent him the application docu ments and forms to fill in.

The letter having been posted by FedEx, the board informed him about the tracking number. Vlad doesn’t know what this means, so he asks Boris, his brother-in-law,about FedEx.

Vlad: Hi, Boris,I have got a little problem.

Boris: What is it? What is the matter?

Vlad: I saw you receive a parcel with a sign FedEx several times.Boris: Well,I use their service quite often. Why are you asking?Vlad: You see,I must get a letter sent by FedEx, andI don’t know what I am to do.

Boris: You know, it is rather simple. FedEx is an American compa ny specializing in delivering letters, parcels and goods. In fact, it is a carrier service, or an express transportation com pany. There are quite a lot of companies of this kind all over the world, say, DHL, FedEx, German Parcel, etc.

Vlad: Then, in what way are they different from traditional postal service?

Boris: In fact, there is a great difference. To begin with, they are more reliable than the regular post. Having something really important to be sent, you’d better use the service of such company, though their services are not cheap.

Vlad: Does FedEx deliver internationally, being an American com pany?

Boris: Of course, they do. If I am not mistaken, they have repre sentative offices in more than 200 countries.

Vlad: Have they, really? Then,I think,I am sure to receive the documents very soon. But then there is one more question: they have supplied me with the tracking number. What is it needed for?

Boris: Oh, using this number you can track your letter.

Vlad: Where can I track it?

Boris: In the Internet, of course. Just go to FedEx homepage and insert the number you received. You’ll get the complete in formation about where your package is and when it is going to be at your destination. It is interesting sometimes to see that your parcel travels through so many countries to reach you.

Vlad: Do you want to say that their delivery is slower than a usual post service?

Boris: Why do you think so?

Vlad: You said it travels to many countries ...

Boris: No, it is very fast. They choose the best way to deliver. They have their own aircraft and vehicles.

Vlad: It is really very interesting. I wish I knew this before. Now I’d better go and track my parcel.
