It is not only words and word order that are important in your language. The rise and fall of your voice as you speak, and the stress you place on certain words (called “intonation”), also give the listener information.
For a statement (sentence), the voice does not stay at the same level throughout. It slightly rises and falls on key words (like nouns, adjectives, adverbs) and usually drops at the end of the sentence. Depending on the accent of the speaker, these rises and falls may be bigger or smaller.
In these ways, English speakers communicate meaning not only with words, but with intonation.
Instructions. Listen to the audios of native speakers. Note the intonations. Practice repeating each example sentence until you too flow smoothly and naturally.
