Pronunciation: Sentence stress and rhythm

Burning FOSSIL FUELS releases CARBON DIOXIDE. We need CLEANER ENERGY, not just a NEW SLOGAN. Content words form beats; contrast may shift emphasis. Say the second sentence with stress on cleaner, then slogan, and explain the different focus. Keep unstressed words audible without giving every word equal stress.

Grammar and use

A present-participle clause usually has an active meaning: Burning fuel, the engine releases gases. A past-participle clause often has a passive meaning: Heated by sunlight, the surface warms. The understood subject must match the main-clause subject; avoid dangling participles. These shortened clauses may express reason, time or a related action, so expand them to check meaning.
