Okay, thank you!! :D

In this sentence, "commission" is used as a noun, not a verb. The verb would be "are," so this sentence is correct. I hope this helped! serkevtî bin!

I think that reading books is definitely helpful. However, make sure you get a modern book so you don't start talking like Shakespeare. I think the best way to practice with your teacher would be to talk in English about something (like what you did that day) if you're far enough along, and have your teacher correct your mistakes as you talk. That way, you would get practice speaking and pronouncing words, as well as listening comprehension. Another important thing to discuss would be irregular verbs, since those are very confusing.

In the sentence "taihen tanoshii haikingu deshita," the "tanoshii" is describing the hike. The literal translation would be "a very fun hike it was," like Yoda speak, which is correct in Japanese. However, you could also say, "haikingu wa taihen tanoshikatta desu," which means almost the same thing (it may sound more like hiking in general, but it is also grammatically correct). Hope this helped! 日本語を勉強するのは頑張ってね！

In this case, "not" is referring to what was said right before this sentence. The speaker said, "You better pray to God not," meaning, "You better pray to God that does not happen/that is not the case." I hope this helps! :D
