Learning English

When l began to studying English, I used to sing English songs, watch English movies, and read English stories.
l think that singing English songs was my favoite way to learn. It was really helpful and interesting.
Now, l learn English on websites. lt's a good way to study English, and l have got a lot of language partners. That's the real meaning of language, is that right?

You only made two actual mistakes:
1. The plural of “story” is spelled “stories.”

2. In your sentence “l think that singing English songs was my favorite way to learn, it was really helpful and interesting,” you forgot the letter “r” in “favorite” and you should have used a semicolon (;) instead of a comma. Another option would be to use a connector like “because” or “that is to say.” It is not necessary or desirable to start a new sentence, since the two ideas are so closely connected.

Note regarding the other member’s “corrections:”
“Web site” and “website” are both acceptable, although the latter spelling has become much more popular these days.

“I began to study” and “I began studying” are both correct and synonymous in this context.

The comma after “music” (the so-called “Oxford comma”) is absolutely unnecessary here.

l think that singing English songs was my favoite way to learn; it was really helpful and interesting.
Now, l learn English on web sites. lt's a good way to study English, and l have got (perfectly good grammar, although we usually use the contraction "I've") a lot of language partners. That's the real meaning of language, isn't (we use negative tags for affirmative sentences, and vice versa) that right?
