OBLIGATION

SHOULD ,  MUST,  HAVE TO

 It’s 8.15 and school starts at 8.00. Mother to son:

                                              

1 You be at school at this time.

2 You  skip school, it’s bad for your education. It's also against the rules.

3 You  got up so late.

4 You take a bus, I’ll drive you to school.

5 You  go to bed earlier at night. You'd feel more relaxed in the morning.

Tom looks very pale and tired.       

                                                  

1 He studied a lot today.

2 He  rest a little before supper. It would do him good.

3 He  study so hard, he knows his lessons very well.

4 He  gone out for a walk in the middle of the afternoon.

5 He  try to be less scared of tests. He wouldn't suffer so much. 

6 He be very worried about tomorrow’s Maths test. 

Jerry said he would invite me to his party but he didn’t.
                                        

1 He  make false promises.

2 You’re such a fun at parties, he  invited you.

3 You  get offended, he may have forgotten to ring you up.

4 You  think there’s something wrong with you. It was Jerry’s mistake.

5 If  you don’t go to his party, you  buy him a present. That is an advantage!

 Look, there’s going to be a terrible storm soon.

                                         

1 We  hurry home. I think it would be better and safer.

2 We brought an umbrella. We could have walked in the rain.

3 We  stand under a tree. It’s too dangerous.

4 Look, there’s a man selling umbrellas. We absolutely buy one.

5 We  pay very much. I think 5 dollars will be enough.

The house smells of smoke. It’s terrible.
        

1 Tom is in his room, he be smoking and he never closes the door.

2 He  smoke so much. It’s bad for his health.

3 He  smoked at least 10 cigarettes since this morning.

4 You told him that he could smoke in his bedroom.

5 He  try to give up this bad habit.
