Как различать:
There is / There are — когда говорим, что что-то есть, существует, находится:
There is a playground. There is a bus stop. There is someone on the phone.It is — когда говорим о погоде, температуре, времени, расстоянии, а также при идентификации и в выражениях типа it seems that:
It is warm. It is 5 km. It seems that… It is our guide.
Проверка: везде с there стоит единственное число — there is; а it использовано в погоде, расстоянии, устойчивом выражении it seems и при идентификации человека по телефону.
