1 If you are under 16, you have to come with an adult or you can't use the club.

2 The club is free for members. They don't have to pay.

3 Swimmers have to wear a swimming cap in the pool. You can't swim without one.

4 Everyone has to have a shower before going into the pool, or they can't go in.

5 You don't have to bring your own towel or shampoo. We have everything you need here.

6 You have to put your wet towels in the bins. Please do not leave them on the floor.

Объяснение:

• Модальный глагол have to имеет значение обязанности или необходимости.

• Отрицание don't have to переводится как "не нужно", "не должен" и выражает отсутствие необходимости в чем-либо. В случае правил, установленных в организации, речь идет о запретах.
