What Passengers Could Do
Practice note: Grammar examples and role-play details may be hypothetical. Questions explicitly about the article use the reported facts. This is a historical report, not current travel advice.
Words from the text: move a trip, alternative, without paying, under the waiver's conditions, disrupt, impact, affected, flexibility, figures, eligible, conditions
A In Unit 4 you learned to use can for permission or possibility now. Any fee exemption comes from the waiver's conditions, not from can itself.
Eligible passengers can move their trip to an alternative flight without paying extra money.
Right now, affected customers can change their flight under the airline's conditions.
B Use could for permission or possibility that existed in the past. Could is the past form of can. We use it to talk about what was true before, for example during a storm or last week.
Cape Air said that passengers could move their trip to an alternative flight until October 2.
The waiver gave affected passengers more flexibility — they could move their trip without paying extra fees.
Last Saturday, affected passengers could change their flight without paying a fee.
Русскоговорящие часто используют can и для прошлой ситуации («passengers can change...» вместо «could change...»). Для общей возможности в завершённой прошлой ситуации используем could. В косвенной речи can иногда сохраняется, если правило всё ещё действует.
C The negative is couldn't (could not). The question form is Could + subject + verb...?
In this practice scenario, the old ticket rules required a fee, so passengers couldn't change that ticket without paying the fee.
Could passengers travel without paying extra money because of the storm's impact? Yes, they could, under the waiver's conditions.
