1. Do the pairs of sentences mean the same? Write S for same or D for different. If they are different, can you explain why?

1 — D: should = advice, must = strong obligation.

3 — D: doesn’t have to = not necessary, shouldn’t = advice not to do it.

4 — D: ought to = advice, have to = obligation.

5 — D: mustn’t = prohibited, don’t have to = not necessary.
