Tutorial for lesson 1 to lesson five 5 of Oral English (1)
Background knowledge for lesson one and lesson four:
If your health problem is complicated, it is usually best to go to a doctor you trust or someone has recommended. You should remember that medical services, including dental work, in the U.S. are generally very expensive. Appointments are made far in advance, but many doctors and dentists will try to fit you in if you have an urgent problem. In the United States, many people subscribe to private insurance companies for personal coverage. Some large companies and Civil Service employers provide medical coverage for their employees.

Dialogue: At the Doctor's
Doctor: You said on the phone that you feel terrible. What's wrong?
Bob: I've had a terrible stomachache since Saturday night.
Doctor: Any other symptoms? Like diarrhea, nausea.
Bob; Yes, I also feel dizzy.
Doctor: Cay you think of anything you ate for Saturday dinner that might have caused it?
Bob: All I can think of is the fish we had. It didn't taste right.
Doctor: then that might be it. Now normally how have you been feeling?
Bob: Well, I 've been feeling tired for quite sometime.
Doctor: Do you get much exercise?
Bob: As a matter of fact, I don't. And I think I smoke too much, too.
Doctor: Well, that explains why you feel tired. I'll give you some pills to stop your stomach pain. I also recommend that you cut down on your smoking. If you try to get more exercise, your feeling of tiredness will be gone in no time.
Bob: Thank you, doctor.

Background knowledge for lesson two:
It is all right to make plans with friends at the last minute if you invite them to party. It is more polite, however, to plan ahead of time.
Parties, shows and concerts are very popular. It is a good idea to buy tickets in advance if you want to see a particular show or concert.
When going to a cocktail party, it is common to arrive ten minutes late and leave twenty minutes before it is scheduled to end. If you wish to leave earlier, you should at least stay for half an hour. On these occasions you should talk for a few minutes to one person, then move on to talk to another one. Good topics are weather, studies, jobs or what part of China you come from. Do not ask others about their age and income. Questions about age and money are considered rude.
Background knowledge for lesson five:
Traveling is not only a source of pleasure for people these days; it is also "big business'. In other words, lots of companies now exist simply to organize holiday for people. They naturally make a lot of financial profit from this type of business. Newspapers and magazines frequently have articles about different types of holiday. They offer advice on how to select the best holidays, describe different destination, suggest ways of traveling cheaply, comfortably and easily, and recommend good place to stay. They also contain lots of advertisements for different travel companies.
