My hobby is not as popular as the others, and it will be difficult to explain. I am cleaning manga. Manga is Japanese comics. The cleaner is the person who cleans the text from the manga, cleans up the sounds and restores the background. Sometimes he also deals with the initial processing of the scans. I like to do this kind of hobby in my free time and I'm very fond of the process. For this hobby, I can sit until night.

Объяснение:

Present Continues это настоящая продолжаемая время

В этом продолжаемом времени мы используем в глаголах -ing и после местоимении пишем am, is и are

вот, к примеру:

He/She/It is wearing my jeans. ( "is" пишется после местоимении "He/She/It";

и к глаголу "wear" прибавляется окончание "-ing")

I am studying English. (здесь тоже самое но к "I -..." мы пишем "am",

и к глаголу "study" прибавляется окончание "-ing")

We/They/You are going to the party. (после местоимении "We/They/You" пишется "are",

и к глаголу "go" прибавляется окончание "-ing")
