The subordinating clause in the sentence stated above is:
<span>C.as the tides rise and fall
</span>
The clause begins with a subordinate conjunction "as" and contains a subject and verb. Subordinating conjunctions is also referred to as dependent clause because it cannot stand alone and therefore needs the independent clause to express a complete thought.
The sentence that uses a subjective pronoun correctly is the first one - Laura and I have written an original play for this year's festival.
The second sentence is incorrect because the word him is not subjective, and neither is her in the third sentence, or them in the last one.
Some students like the library because the internet is fast and makes working on school projects, abd other related things is quick and easy. Having fast internet allows students to not get frustrated at their computers. One improvement we could make though to help others who can't focus or concentrate on their work is having separate rooms, so students can choose to work in one room with multiple people or in separate rooms by themselves. Additionally the library could offer headphones for those who want to listen to music to help them concentrate.
