Sad Day Sad Day

I was taught a painting today/ I was taught how to make a painting today/ I was taught how to paint something today. I was taught a painting today/ I was taught how to make a painting today/ I was taught how to paint something today.

Other ways of saying it more naturally too!

I was taught painting today. I was taught painting today.

I went to art class today.

I was being taught painting today. I was being taught painting today.

"I was learning about painting today." would sound the most natural, but adding "being" is ok. Saying "I was taught X" implies you learned X completely. "I was being taught X" means you are learning about X.

I was taughtlearned how to painting today. I learned how to paint today.

Or alternatively: "I took a painting class" "I was taught painting today" is in the passive voice and leaves a lot of questions: who taught you? Where were you taught?

I was taughtWe had a painting class today. We had a painting class today.

This one sounds more natural.

I was taughtlearning how to painting today. I was learning how to paint today.

"I was taught" has a sense of completeness to it, like you had the lesson and now you know how to paint, and have nothing further to learn. Saying you were learning (or attending a class, as I see someone else suggested) conveys the sense of an ongoing process better.

I was taughthad a painting lesson today. I had a painting lesson today

sounds more fluid

Recently, I haven't improved in skill.

FinallyIn the end, I was scolded by teacher. In the end, I was scolded by teacher.

Finally, I was scolded by teacher. Finally, I was scolded by teacher.

I ended up being scolded by the teacher.

Finally, I was scolded by the teacher. Finally, I was scolded by the teacher.

Finally, I was scolded by teacher. I was scolded by teacher.

"Finally" makes more sense in the context of you giving an explanations of a variety of things that happened. Since that didn't precede this sentence, I just removed the word altogether.

Finally, I was scolded by the teacher. Finally, I was scolded by the teacher.

Finally, I was scolded by the teacher. Finally, I was scolded by the teacher.

Finally, I was scolded by teacher. I was scolded by teacher.

"Finally" is a little awkward here as in the context it gives the image of the teacher getting fed up and yelling at you and the idea that this was overdue.

I'm sad, but I should practice more and more. I'm sad, but I should practice more.
