What is the difference between 阅读, 读, and 看? What is the difference between the three read verbs, 阅读，读，and 看? A casual googling gets you some explanations but as I still can't get it correctly and it has not been posted here, I wish someone could clarify it.

I understand the difference of the three verbs from 念; 念 is used when you speak it out, sometimes loudly.

But as to the three verbs, 看 is used in more general while 阅读 is used when you concentrate on the action of reading...right?

And then I don't know the difference between 阅读 and 读. 

Also, does 阅读 (or 读) is only used when you read words or sentences? For example, I'm now at Starbucks and see a trash bin outside, around 10m ahead. Is it awkward to say 请阅读那个垃圾桶?

In most books I used I saw 看 is most often used, but during my current stay in China (too short yet), I have seen 阅读 far more often than 看...
看 could mean see, look, watch and read, but 阅读 does not mean see, look or watch. 阅读 only means read. Examples: 


我在看书。(I'm reading a book.)
我在读书。(I'm reading a book.)
我在阅读。(I'm doing some reading.)(Normally we don't say 我在阅读书; see below.)
WRONG SENTENCE: 请阅读那个垃圾桶。(Please read that trash bin.)
请看那个垃圾桶。(Please look at that trash bin.)

阅读 is more like an intransitive verb, or a noun in English, while 读 is more like a transitive verb. Examples:


我喜欢阅读。(I like reading.)
UNNATURAL: 我喜欢阅读书。(I like reading books.)(Although in English it is very good, it sounds weird in Chinese, because a one-syllable word is combined with a two-syllable word.)
RATHER FORMAL: 我喜欢阅读书籍。(I like reading books.)(This sounds formal rather than weird because two two-syllable words are put together.)
