Sentence: "If I were to speak in front of the audience, I would feel a wave of anxiety."
Explanation: The sentence uses the conditional mood because it expresses a hypothetical situation that depends on a condition (speaking in front of an audience). The use of "would feel" indicates that anxiety is a consequence of this imagined scenario occurring, rather than a statement about a present reality. The structure "if... were to" further emphasizes the conditional nature of the situation, as it reflects uncertainty and possibility rather than certainty.
