Climate change profoundly impacts ecosystems by forcing species to shift ranges, disrupting food webs, increasing extreme events like wildfires, and reducing resilience, leading to habitat loss, biodiversity decline, and even extinctions, with marine life suffering from warming/acidification and terrestrial systems facing drought, insect outbreaks, and altered plant life, stressing nature's ability to provide essential services like clean water and food. Key Impacts on Land: * Habitat Shifts & Loss: Plants and animals move to cooler, higher elevations or latitudes, but can't always keep pace with rapid change, causing habitat fragmentation and loss. * Altered Timing (Phenology): Earlier berry ripening affects bear diets (e.g., less salmon), disrupting food webs. * Increased Disturbances: Hotter, drier conditions fuel more intense wildfires and insect outbreaks, destroying habitats. * Invasive Species: Stressed ecosystems allow invaders like cheatgrass to thrive, d...
At B2 level, the "-ing" form (gerund/present participle) is used extensively for continuous tenses (e.g., I am working), as subjects/objects (Swimming is fun), after certain verbs (enjoy, avoid, finish), after prepositions (used to, look forward to), and in reduced relative clauses (the man sitting there), requiring fluency in recognizing patterns like "verb + -ing," "-ing" as nouns, and complex constructions like "with + -ing". Key Uses at B2 Level: 1. Continuous Tenses: Forming present, past, future continuous tenses (e.g., She was cooking dinner). 2. Gerunds (Noun Form): * As Subjects: Reading novels helps improve vocabulary. * As Objects of Verbs: I enjoy reading. * After Prepositions: Thanks for helping. * After Certain Expressions: It's no use crying over spilled milk. 3. Verbs Followed by "-ing": Mastering verbs like admit, avoid, consider, dislike, finish, give up, miss, suggest, etc., that require the -in...
