okay, so i have this English test tommorow morning on subjects & predicates, can u please help me!!!

My first question is, I know that a prepositional phrase isn't supposed to be included in the simple subject, but can it be included in the complete subject?
For Example : On Beartooth Highway in Montana, excellent campgrounds and scenic overlooks provide many views of distant glaciers.
CS - On Beartooth Highway in Montana, excellent campgrounds and scenic overlooks
SS - campgrounds and overlooks
CP - provide many views of distant glaciers.
SP - provide
Would this be correct?

Secondly, this sentence confused me a little - Sacagawea of the Shoshones helped open the West.

CS - Sacagawea of the Shoshones
SS - Sacagawea
CP - helped open the West
SP - helped open

Is this correct? I m confused because of the "helped." Would that be included in the simple predicate?

My first question is, I know that a prepositional phrase isn't supposed to be included in the simple subject, but can it be included in the complete subject? sometimes; only if it's modifying that subject

For Example : On Beartooth Highway in Montana, excellent campgrounds and scenic overlooks provide many views of distant glaciers.
CS - On Beartooth Highway in Montana, excellent campgrounds and scenic overlooks No, just "excellent ... overlooks" is the complete subject.
SS - campgrounds and overlooks yes, but I think without the conjunction "and"
CP - provide many views of distant glaciers. yes
SP - provide yes
Would this be correct?
I think the prepositional phrases at the beginning of the sentence are more adverbial than adjectival.

Secondly, this sentence confused me a little - Sacagawea of the Shoshones helped open the West.

CS - Sacagawea of the Shoshones
SS - Sacagawea
CP - helped open the West
SP - helped open
Only "helped" is the SP; "open" is part of an infinitive, except that the word "to" (in front of "open" has been omitted.

Is this correct? I m confused because of the "helped." Would that be included in the simple predicate?
Is the above explanation clear?

??

Sure, I'd be happy to help you with your English test!

Regarding your first question, you are correct that a prepositional phrase is not usually included in the simple subject of a sentence. However, it can indeed be included in the complete subject. In the example you provided, "On Beartooth Highway in Montana, excellent campgrounds and scenic overlooks" is the complete subject because it includes the prepositional phrase "On Beartooth Highway in Montana." The simple subject would be "campgrounds and overlooks."

For your second question, you have analyzed the sentence correctly. "Sacagawea of the Shoshones" is the complete subject, and "Sacagawea" is the simple subject. "Helped open the West" is the complete predicate, and "helped open" is the simple predicate. The word "helped" is indeed part of the simple predicate because it is the verb that shows the action or state of being.

To determine the simple subject, you need to identify the main noun or pronoun that the sentence is about. The simple predicate, on the other hand, is the main verb or verb phrase that tells what the subject is doing or experiencing.

I hope this helps! Let me know if you have any more questions.
