Lesson 25 must / have to / had to

Choose the correct answers:

  1. When most people visit a foreign country, they __________ (must, have to, had to) get a passport and a visa.
  2. My cousin __________ (must, has to, had to) get his passport and visa before he came to study in the United States.
  3. He also __________ (must, has to, had to) arrive here before the semester started.

Explain:

“Must”, “have to”,  and “had to” all explain responsibilities, obligations, and necessities.

must, have to:   They are for current or future situations. “Must” is stronger than “have to”.

had to:   It is for past situations.  It is the past tense of “must” and “have to”.

  • In Sentence #1, it is about the current official law. Both “must” and “have to” are correct, but “must” has a stronger and more formal tone.
  • In Sentence #2 and #3, the context shows that the actions occurred in the past, so the past tense “had to” is used.
