As you said 着 is a present progressive marker but can only be used right after a verb. Imagine if some one says, "I am ing-watch TV." It's ungrammatical. However, what is different is that 着 only refers to an action that is taking place right now. It can be an observable moving like "我读着书" = "I am reading (a) book (right now)", or can be abstract like "国家正在发展着" = "The country is right now developing (right now)". * 正在and着 both means present progressive and it looks redundant, but... well, it is. :p But it is how people use it. For the counter particle 本, you can try this N + V + (# + counter) + adj + N. (#+Counter) group and adj can be reversed. Don't miss the number.

各位认真想想， 中国人究竟是怎样说话的? Andrea, 你想说话像个中国人，还是像个不伦不类的老外? I think native Chinese speakers, when not under the undue influence of an English sentence and when NOT under pressure to translate, would say, as a matter of natural Chinese speech, "我在看一本中文小说/童话选/短篇故事选， 很好看。" 中国朋友们，其实英语"interesting"在这里的意思是"好看"。拿着英汉字典来阅读英语是不行的，要明白了英语世界的思维才真的有能力去翻译得准确的。"interesting"是最不好明白的英文字之一。 I know of no native Chinese speakers who would speak Chinese by first constructing an English sentence and then pausing to translate it.

Yes. When you've finished reading it, you can say"我看了一本很有意思的书。" or "我读了一本很有意思的书。" The verb can be translated as "看" or "读" both are correct in this context. "看" emphasizes "look at" or "watch" （e.g. 看电视(watch TV)） “读” has a deeper meaning with more thinking or reciting. Both are OK in spoken or writing Chinese.

1. "我看了很有意思的本书 "不正确。应该说“我看了一本很有意思的书"，或者”我看了很有意思的一本书“。 2. ”本书“ means ”this book“。”一本书“ means " a book"。”书本“ means "books"

you have got it！should like this：我看了本很有意思的书
