英文grammar 問題 plz help

Sometimes it is impossible to tell which one is correct if you do not give us the whole sentence.

1. Both are possible. The word exercise can be a countable or an uncountable noun. It depends on the meaning of the word in that particular sentence.

2. 'Come across' is a phrasal verb. It should be followed by a noun or noun phrase.

3. "Indicate" is a transitive verb. It should be 'students' instead of 'student'.

4. Between my friends and me. I cant imagine how this phrase can be used as the subject of a sentence. Sometimes it might be placed at the beginning of a sentence, but still it is not the subject. e.g. Between my friends and me, we shared the money. This sentence can be rewritten as 'We share the money between my friends and me.'
Have you ever heard 'the two of we'? Never! 'the two of us' is what you have heard, right?

Nowadays, many people say "between my friends and I". So I think maybe it is ok to say that although 'between my friend and me' is grammatically correct.

[My friend and I] is correct because both are the subjects of a sentence. For example: [My friend go swimming.] & [I go swimming.], both [My friend] and [I] are the subjects. If you combine the 2 sentences together, it becomes [ My friend and I go swimming together.]

In fact, you can change the position of the 2 subjects and it becomes: [I and my friend go swimming togehter.] & it cannot be [ Me and my friend go swimming together.] because [me] is an object (e.g. My friend go swimming with me. / He cannot see me.).

It just that [I and my friend] is very uncommon in typical English and people usually tend to say [XXX and I]. I honestly do not know why that is so, maybe they want to show respect to others so they purposely put [I] at last.

Anyway, its function does not change although it is not placed at the first position of a sentence. It still serves as a subject.

As for 'the two of us', it is grammatically different from [my friend and I], so I do not think these 2 kinds of expression can be related and 'the two of us' is not an appropriate example to explain the expression [my friend and I].

Of course the expression of 'the two of us' is absolutely correct and there is no such thing as 'the two of we', but the explanation for such a saying is completely different from the one for [my friend and I].

According to standard English grammar, the pronouns (e.g. he / him / they / we / her, etc) placed after the preposition [of] are mostly or even must be in object form. It is too complicated to explain the reason here (it will take very long and I can't type too much due to lack of space).

But I can tell you this is the rule of the game (I mean English). Other examples for such expression are : [both of them], [none of us], [neither of them], [either of us], [some of them], [one of us]....etc.

Please take note if you change such expression to [Something XXX and XX] and the second subject is [I], you still have to use [I] instead of [me]. E.g. [Both Julia and I] but not [Both Julia and me] because there is no more [of] in the expression!
