EN: The noun clause introduced by 'that' ('that microscopic particles... can traverse...') acts as an appositive to the noun 'evidence', defining the specific content of the evidence.

EN: The adverbial phrase 'for the first time' is placed between the auxiliary verb 'have' and the past participle 'identified' to emphasize the historical significance of the action.

EN: The McMurdo Dry Valleys in Antarctica are among the most extreme deserts on Earth, historically used by NASA to simulate Martian conditions due to their extreme cold and dryness. The discovery of nanoplastics here is culturally and scientifically significant because it shatters the illusion that any part of our planet remains truly 'untouched' by human industrial activity.
EN: The use of past participle phrases as post-modifiers. In this sentence, 'published in the journal Nanoplastics' and 'collected from the McMurdo Dry Valleys' are past participle phrases modifying 'The groundbreaking study' and 'soil samples' respectively. They function as shortened relative clauses (which was published... / which were collected...).
The data collected from the weather stations indicated a sudden drop in temperature.
EN: Noun clauses introduced by 'that' as direct objects. The verb 'revealed' is followed by a noun clause 'that soil samples... polymers' which functions as the direct object of the main verb, reporting the findings of the study.

EN: The prepositional phrase 'alongside' used to mean 'together with' or 'in addition to'. It is commonly used in formal and scientific writing to introduce items that coexist or occur together with the primary subject of discussion.

EN: The McMurdo Dry Valleys in Antarctica are among the most extreme deserts on Earth, characterized by extremely low humidity and minimal ice cover. Historically considered pristine and untouched by direct human industrial activity, the discovery of nanoplastics here is culturally and environmentally significant, highlighting the global reach of human-made pollution even to the most remote corners of the planet.
EN: The noun clause introduced by 'that' functions as the direct object of the reporting verb 'emphasized'. This structure is commonly used in academic and journalistic writing to report findings, assertions, or beliefs.

EN: The past participle phrase 'situated among...' functions as an adjective clause (reduced relative clause) modifying the noun phrase 'The McMurdo Dry Valleys'. It is a shortened form of 'which are situated among...'.

EN: The McMurdo Dry Valleys in Antarctica are one of the most extreme deserts on Earth, characterized by extremely low humidity and surrounded by mountains that prevent the flow of ice. Because of their cold, dry, and wind-swept conditions, they are considered the closest terrestrial equivalent to the environment on Mars. This makes the discovery of human-made nanoplastics there particularly shocking to the scientific community.
EN: The noun clause introduced by 'that' functions as the direct object of the reporting verb 'suggests'. It contains a complete sentence structure: 'atmospheric transport (S) carries (V) nanoplastics (O)'.
Recent data suggests that global temperatures are rising faster than previously projected.
EN: The prepositional phrase 'far beyond...' acts as an adverbial modifier, indicating a location or extent that exceeds a certain limit. 'Far' is used as an intensifier before the preposition 'beyond'.

EN: The verb 'go' can function as a copular (linking) verb meaning 'to become' or 'to remain in a certain state', typically followed by an adjective or a past participle with a negative connotation (e.g., go unnoticed, go unpunished, go hungry).

EN: The sentence highlights a shift in environmental science and public discourse. While 'microplastics' (particles smaller than 5mm) have been the focus of ecological concern for over a decade, 'nanoplastics' (particles smaller than 1 micrometer) represent a newly understood, more insidious threat due to their ability to cross biological barriers, reflecting how scientific terminology and environmental priorities evolve over time.
EN: The sentence begins with a participial phrase ('Measuring less than...') acting as an adverbial modifier. This structure is a reduced relative clause or adverbial clause of reason/condition, sharing the same subject as the main clause ('these microscopic particles').

EN: The mention of 'Antarctic interior' and 'Greenland' highlights the global reach of environmental issues. Historically, these regions were considered pristine and isolated from industrial impact.
