Complex Sentence with an adverbial clause of time

Explanation:

A complex sentence is a sentence which comprises a main/an independent clause and one or more subordinate/dependent clauses. A main/an independent clause can stand on its own whereas a subordinate/dependent clause although it has a subject & a verb it cannot stand on its own, example I like to have salads before I start the main course.

The subordinate clause in complex sentence are noun clause, adjectival clause, and adverbial clause. A noun clause starts with words such as that, how, that, where, whether, what, whatever, when, who, whoever, which, whichever, whom, why, and whomever. An adverbial clause functions as an adverb, and entire clause modifies an adjective, a verb, or another adverb; it usually starts with a subordinating conjunction. An adjective clause usually comes after the noun it modifies and is made up of many words and comprise a subject as well as a verb

Examples,
