Adverb Clauses of Time: when, before, after, until, as soon as

Adverb clauses of time tell us when something happens by using subordinating conjunctions like when, before, after, until, and as soon as. For example, "I'll call you as soon as I land" or "Before the cabin is depressurized, fasten your helmet."

In this challenge, you will help chaotic chefs time their recipes, guide astronauts through pre-flight checklists, decode a time traveler's journal, and plan a spy mission — all while mastering tricky grammar rules. You will practice choosing the right time conjunction for each context, using the correct verb tense in future time clauses (present simple, not will!), and sequencing past events with the right combination of past simple and past perfect.

You will work through 15 questions in a fun mix of single-choice, multi-choice, drop-down, and drag-and-drop formats.
