Residing in the arid desert of central Australia presents numerous challenges, among which the procurement of water stands out as particularly formidable.
Analysis:
The prepositional phrase "of which" signals a non-restrictive relative clause. To comprehend the relationship denoted by "of," we must first identify its antecedent, "challenges." Based on the antecedent's collocation, we can infer that "of" expresses a subordinate relationship. Alternatively, we might opt to select "of" predicated on the verb搭配within the relative clause. Non-restrictive relative clauses serve as supplementary descriptions for nouns or pronouns. They are not essential and can be omitted without altering the sentence's meaning. They are typically separated from the noun they modify by a comma.
In this case, "of which" introduces a non-restrictive relative clause that further explains the challenges encountered in the Australian desert. The relative clause is "obtaining water is not the least of the problems." By substituting its antecedent, "problems," into the relative clause, we arrive at the complete thought:
"Obtaining water is not the least of the problems challenges."
It is crucial to possess the ability to identify the relative pronouns within relative clauses. This requires an understanding of the usage of each relative pronoun. Next, it is essential to pinpoint the antecedent and incorporate it into the relative clause. Finally, we can utilize the antecedent's role within the relative clause to ascertain the relative pronoun.
Language Point:
"Not the least of the problems" connotes not a minor issue but a significant one.
Translation:
Inhabiting the parched desert of central Australia presents many obstacles, of which obtaining water is a particularly formidable one.
