Warming up by learning about what is obligation

Hello, class. We shall learn to talk about “obligation” or lack of “obligation”. But first what is “obligation”?

It is a noun, meaning

1. A moral or legal duty or tie.

2. The binding power of such a duty or tie.

3. A debt of gratitude for a service.

Example:

be under obligation to her

If you have not signed a contract, you are under no obligation to (= it is not necessary to) pay them any money. You have a legal obligation to (= The law says you must) ensure your child receives a proper education. I haven't got time to do his work for him - I've got too many obligations as it is. A tender conscience is a stronger obligation than a prison.

Every man has obligations which belong to his station.

Duties extend beyond obligation, and direct the affections, desires, and intentions, as well as the actions.

She will study English for five months and then go to Columbia University in New York to study engineering. ●Small Talk Dialogue

Maria: The service is really slow here. I've been trying to get the waiter's attention for the last ten minutes.

Ali: I hope he waits on us soon. I have a class at two o'clock.

Maria: Me, too. I recognize that English book. You must be a student at the English

Language Center.

Ali: Yeah. I'm in the fourth course. Are you studying there?

Maria: Yes, I'm in the fifth course. I took the fourth course last month.

Ali: I just came here two weeks ago. Do you like the institute?

Maria: It's pretty good. I think I've learned a lot of English so far.

Ali: Yeah. I only wish the classes were a little smaller, though, because we don't get enough chance to talk. But I like my teachers a lot.

Maria: How long are you going to be here?

Ali: I guess a year, but sometimes I feel like going home tomorrow.

Maria: You'll get used to it. Where are you from?

Ali: Saudi Arabia. How about you?

Maria: Venezuela. I'm only staying here three more months. Then I go to Columbia University in New York.

●Points to Remember

★When you first meet most American's, it's impolite to talk about certain things such as salary, age, sex, and religion.

★Introduce yourself casually in informal situations. As the conversation develops, a simple introduction, such as "By the way, my name is..." is generally considered sufficient.

★If a friend comes along and stops to talk, informally introduce him or her to the person you are talking to. It is helpful to provide some information about each of them so that each will 1) know what your relationship is to the other person (friend, neighbor, wife, brother, teacher) and 2) have some information with which to begin a

conversation.

★When we are introduced to someone informally, we usually respond with "Nice to meet you" or "Hi, how are you?" "How do you do?" is used in more formal situations and the response to this expression is generally "How do you do?"
