MUST, HAVE TO, SHOULD (OBLIGATION)

Modal Verbs of Obligation

We can use have to + infinitive, must + infinitive and should + infinitive to express obligation (something you have to do).

Present	Positive	Negative
have to / don’t have to	strong obligation (possibly from outside) Children have to go to school. (sometimes ‘have got to’)	no obligation I don’t have to work on Sundays. You don’t have to eat anything you don’t like.
must / mustn’t	strong obligation (possibly based on the speaker’s opinion) I must study today.	negative obligation You mustn’t smoke here.
should / shouldn’t	mild obligation or advice You should save some money.	mild negative obligation or advice You shouldn’t smoke so much.

Be careful about the difference between mustn't and don't have to!
Mustn't means it's not allowed, or it's a bad idea:

• You mustn't eat so much chocolate, you'll be sick

Don't have to means you don't need to do something, but it's fine if you want to do it:

• I don't have to get up early at the weekend
  (of course, if I want to get up early, that's fine, but I can stay in bed if I want

Past	Positive	Negative
had to / didn’t have to	obligation in the past I had to go to wear a school uniform when I was a child.	no obligation in the past We didn’t have to go to school on Saturdays.
must*	changes to 'had to'	-
should have + pp / shouldn’t have + pp	a past action which didn’t happen: the advice / regret is too late You should have gone to bed earlier, now you have missed the train.	a past action which didn’t happen: the advice / regret is too late You shouldn’t have taken that job., it was a bad idea.

* Remember ‘must have done’ is a modal verb of deduction or speculation, not obligation in the past. For example: Julie must have left. Her coat’s not here.

Complete List of Present Perfect Forms

USE 1 Unspecified Time Before Now

We use the Present Perfect to say that an action happened at an unspecified time before now. The exact time is not important. You CANNOT use the Present Perfect with specific time expressions such as: yesterday, one year ago, last week, when I was a child, when I lived in Japan, at that moment, that day, one day, etc. We CAN use the Present Perfect with unspecific expressions such as: ever, never, once, many times, several times, before, so far, already, yet, etc.

Examples:

• I have seen that movie twenty times.
• I think I have met him once before.
• There have been many earthquakes in California.
• People have traveled to the Moon.
• People have not traveled to Mars.
• Have you read the book yet?
• Nobody has ever climbed that mountain.
• A: Has there ever been a war in the United States?
  B: Yes, there has been a war in the United States.

How Do You Actually Use the Present Perfect?

The concept of "unspecified time" can be very confusing to English learners. It is best to associate Present Perfect with the following topics:

TOPIC 1 Experience

You can use the Present Perfect to describe your experience. It is like saying, "I have the experience of..." You can also use this tense to say that you have never had a certain experience. The Present Perfect is NOT used to describe a specific event.

Examples:

• I have been to France. This sentence means that you have had the experience of being in France. Maybe you have been there once, or several times.
• I have been to France three times. You can add the number of times at the end of the sentence.
• I have never been to France. This sentence means that you have not had the experience of going to France.
• I think I have seen that movie before.
• He has never traveled by train.
• Joan has studied two foreign languages.
• A: Have you ever met him?
  B: No, I have not met him.

TOPIC 2 Change Over Time

We often use the Present Perfect to talk about change that has happened over a period of time.

Examples:

• You have grown since the last time I saw you.
• The government has become more interested in arts education.
• Japanese has become one of the most popular courses at the university since the Asian studies program was established.
• My English has really improved since I moved to Australia.

TOPIC 3 Accomplishments

We often use the Present Perfect to list the accomplishments of individuals and humanity. You cannot mention a specific time.

Examples:

• Man has walked on the Moon.
• Our son has learned how to read.
• Doctors have cured many deadly diseases.
• Scientists have split the atom.

TOPIC 4 An Uncompleted Action You Are Expecting

We often use the Present Perfect to say that an action which we expected has not happened. Using the Present Perfect suggests that we are still waiting for the action to happen.

Examples:

• James has not finished his homework yet.
• Susan hasn't mastered Japanese, but she can communicate.
• Bill has still not arrived.
• The rain hasn't stopped.

Future tenses

There are several different ways in English that you can talk about the future. This page is an introduction to the most important ones:

Predictions/statements of fact

The auxiliary verb will is used in making predictions or simple statements of fact about the future.

• The sun will rise at 6.30 tomorrow.
• Lunch break today will be 10 minutes longer than usual.
• In the year 2050 all students will have their own computers in school.
• If you help me, I will help you.
• Do you think she will come soon?
• You won't pass your exams if you don't start working harder.
• I know my parents won't let me go to the party.
• Will it snow for Christmas?
• I know she's sick, but will she be back in school tomorrow?

Intentions

The auxiliary verb going to is used in talking about intentions. (An intention is a plan for the future that you have already thought about.)

• We're going to buy a new car next month.
• I'm going to work in a bank when I leave school.
• In the new year I'm going to stop eating so much junk.
• He's not going to go to the dance. He's got too much work.
• I'm not going to watch TV until my science project is finished.
• Are you going to play basketball after school?
• What are you going to have for lunch today?

Note: going to is often used in the past tense to talk about an unfulfilled intention. Examples: I was going to study for my grammar test, but I had no time. / He was going to call you, but he couldn't find his mobile phone. / My grandmother was going to visit us, but she fell and broke her arm.

Arrangements

The present continuous tense is used in talking about arrangements. (An arrangement is is a plan for the future that you have already thought about and discussed with someone else.)

• I'm meeting my mother at the airport tomorrow.
• Our grandparents are visiting us this Christmas.
• Sorry, I can't stay after school today; I'm playing tennis with Jun-Sik.
• My sister's going to the dentist tomorrow.
• I'm not returning home for the holidays, so I can come to your party after all!
• Are you doing anything on Sunday morning?
• Do you know if he is going to the dance with Maiko next week?

Scheduled events

The present simple tense is usually used to refer to future events that are scheduled (and outside of our control).

• Hurry up! The train departs in 10 minutes.
• I leave Frankfurt at 5 o'clock in the morning and arrive in New York
at midnight the next day.
• She has an appointment with the headmaster after school today.
• There's no need to hurry. The train doesn't leave for another 30 minutes.

Examples:

• I did not have any money because I had lost my wallet.

FORM

[VERB+ed] or irregular verbs

Examples:

Complete List of Simple Past Forms

USE 1 Completed Action in the Past

Use the Simple Past to express the idea that an action started and finished at a specific time in the past. Sometimes, the speaker may not actually mention the specific time, but they do have one specific time in mind.

Examples:

• I saw a movie yesterday.
• I didn't see a play yesterday.
• Last year, I traveled to Japan.
• Last year, I didn't travel to Korea.

USE 2 A Series of Completed Actions

We use the Simple Past to list a series of completed actions in the past. These actions happen 1st, 2nd, 3rd, 4th, and so on.

Examples:

• I finished work, walked to the beach, and found a nice place to swim.
• He arrived from the airport at 8:00, checked into the hotel at 9:00, and met the others at 10:00.
• Did you add flour, pour in the milk, and then add the eggs?

USE 3 Duration in Past

The Simple Past can be used with a duration which starts and stops in the past. A duration is a longer action often indicated by expressions such as: for two years, for five minutes, all day, all year, etc.

Examples:

• I lived in Brazil for two years.
• Shauna studied Japanese for five years.
• They sat at the beach all day.

USE 4 Habits in the Past

The Simple Past can also be used to describe a habit which stopped in the past. It can have the same meaning as "used to." To make it clear that we are talking about a habit, we often add expressions such as: always, often, usually, never, when I was a child, when I was younger, etc.

Examples:

• I studied French when I was a child.
• He played the violin.
• He didn't play the piano.

USE 5 Past Facts or Generalizations

The Simple Past can also be used to describe past facts or generalizations which are no longer true. As in USE 4 above, this use of the Simple Past is quite similar to the expression "used to."

Examples:

• She was shy as a child, but now she is very outgoing.
• He didn't like tomatoes before.
• Did you live in Texas when you were a kid?
• People paid much more to make cell phone calls in the past.

IMPORTANT When-Clauses Happen First

Clauses are groups of words which have meaning but are often not complete sentences. Some clauses begin with the word "when" such as "when I dropped my pen..." or "when class began..." These clauses are called when-clauses, and they are very important. The examples below contain when-clauses.

Examples:

• When I paid her one dollar, she answered my question.
• She answered my question when I paid her one dollar.

When-clauses are important because they always happen first when both clauses are in the Simple Past. Both of the examples above mean the same thing: first, I paid her one dollar, and then, she answered my question. It is not important whether "when I paid her one dollar" is at the beginning of the sentence or at the end of the sentence. However, the example below has a different meaning. First, she answered my question, and then, I paid her one dollar.

Example:

• I paid her one dollar when she answered my question.

ADVERB PLACEMENT

The examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.

Examples:

• You just called Debbie.
• Did you just call Debbie?

ACTIVE / PASSIVE

Examples:

• Tom repaired the car. Active
• The car was repaired by Tom. Passive

Past Continuous

FORM

[was/were + present participle]

Examples:

• You were studying when she called.
• Were you studying when she called?
• You were not studying when she called.

Complete List of Past Continuous Forms

USE 1 Interrupted Action in the Past

Use the Past Continuous to indicate that a longer action in the past was interrupted. The interruption is usually a shorter action in the Simple Past. Remember this can be a real interruption or just an interruption in time.

Examples:

• I was watching TV when she called.
• When the phone rang, she was writing a letter.
• While we were having the picnic, it started to rain.
• What were you doing when the earthquake started?
• I was listening to my iPod, so I didn't hear the fire alarm.

USE 2 Specific Time as an Interruption

In USE 1, described above, the Past Continuous is interrupted by a shorter action in the Simple Past. However, you can also use a specific time as an interruption.

Examples:

• Last night at 6 PM, I was eating dinner.
• At midnight, we were still driving through the desert.
• Yesterday at this time, I was sitting at my desk at work.

IMPORTANT

In the Simple Past, a specific time is used to show when an action began or finished. In the Past Continuous, a specific time only interrupts the action.

Examples:

• Last night at 6 PM, I ate dinner. I started eating at 6 PM.
• Last night at 6 PM, I was eating dinner. I started earlier; and at 6 PM, I was in the process of eating dinner.
