Adverb clause

Explanation:

The sentence consists of two clauses: an adverb clause which it's “After a long day of hard work was over” and that we can identify as such because it begins with the subordinating conjunction “After” and it provides information about time; and an independent clause: “Tom went to the lake” which is also the main clause because it expresses a complete idea.

Adverb clauses may be placed at the beginning, middle or end of the sentence. The grammar rule holds that when an adverb clause begins a sentence, a comma must follow, just like it is in the sentence. Therefore, the function of the introductory comma of the sentence is to separate the adverb clause from the main clause.

3. perhaps it was just me, but the air in the laboratory began to thicken as i found myself having difficulty to breathe.

4. i turned to look at him fully as i mentally prepared myself for what my very first words would be to thomas edison.

5. the next couple of seconds shocked me. it wasn't me who spoke, but rather him and with diction i could never think of using in a simple sentence.
