[Grammar] all/all of

[sandy319]

Hello,
Could you explain the usage of "all" and "all of", please?
When should I use the "all"?
When should I use the "all of"?

For example,

______ people in the club like playing the basketball.
______ my students work hard.
______ flesh is mortal.
______ us enjoyed the trip.
______ the students are girls.
______ my heart likes the you.

Which one is the correct word for each sentence. why?

Thanks for your help. ^^

All of is used when the following word is a pronoun such as it, us, you...
In other cases, you should use all

Not necessarily, ‘all’ is an adjective so it can describe a noun or pronoun followed by it to refer to whole quantity(All flesh is mortal.) or number(All the students are girls) or degree (with all due respect) etc
‘all of’ is used as pronoun to refer to whole quantity or whole number; as
All of life’s ingredients are found in Orion Nebula
All of us are included in the team.
All of us enjoyed the trip..
all of a sudden is an idiomatic expression used as adverb; as:
We were having a nice talk, when, all of a sudden, she started shouting.
