Hi guys!
Hoje é dia de aprender mais sobre as preposições ´in´ and ´on´ para fontes de informação.
Veja os exemplos:

IN (written material) – book, magazine, newspaper, etc.

´She read it in a book.´
´Did you see the picture of the president in today´s newspaper?
´I read this great article in the journal ‘English Class.´

ON (electronically) – the radio, the Internet, telephone, TV, etc.
´I heard a new song on the radio.´
´She watched a sitcom on TV.´
´We found Class Idiomas resources on the Internet.´

Já sabiam como usar essas preposições? :D
See you soon guys.
