Решение:
Чтобы поставить предложения с конструкцией 'There is/are' (существует/существуют) в отрицательную форму, нужно добавить частицу 'not' после глагола 'is' или 'are'. Если глагол стоит в прошедшем времени, используются 'was not' (wasn't) или 'were not' (weren't). Также, если в утвердительном предложении было 'some', в отрицательном чаще используется 'any'.
