This advanced grammar structure adds a dynamic sense to your English, allowing you to emphasize the temporary or continuous nature of an action. For example, you might say <span data-no-translation>She seems to be working late tonight<\/span> to comment on an ongoing situation, highlighting that the action is happening right now. Similarly, <span data-no-translation>I need to be focusing more on my studies<\/span> expresses an ongoing intention. When used with modals, as in <span data-no-translation>You should be studying for your exam<\/span>, it can criticize a current action. Mastering continuous infinitives significantly enhances your ability to express nuanced meanings and complex ideas in C1 English.<\/div>\n<h2>What Are Continuous Infinitives?<\/h2>\n<p>A continuous infinitive is a verb form that emphasizes an action is currently happening or is ongoing over a period of time.
