Download this free B2–C1 grammar worksheet PDF for English learners and teachers. This lesson helps students practise unless, as long as, provided that, even if and even though to express conditions, requirements, hypothetical situations and contrasts.
Students learn how to use unless + clause to express a negative condition. The worksheet explains that unless usually means if…not and gives examples such as Unless the queue gets shorter, we’ll book online and We won’t start unless everyone is ready.
The worksheet also teaches as long as for conditional permission and agreements. Students practise sentences such as You may join the workshop as long as you register beforehand. They also learn that as long as can express duration, meaning for the whole time that, as in The lights will stay on as long as the generator works.
Students practise provided (that) + clause to express conditions that must be satisfied, particularly in formal rules, contracts and agreements. Examples include Access is granted provided that visitors follow the safety rules. The lesson helps students distinguish the more formal tone of provided that from the everyday use of as long as.
The worksheet also explains even if for possible or imagined situations that would not change an outcome. Students practise examples such as Even if the forecast improves, I’ll take a coat and hypothetical sentences such as Even if I inherited a fortune, I wouldn’t give up teaching.
An important part of the lesson is distinguishing even if from even though. Students learn that even if introduces a possible or imagined situation, while even though introduces an established fact. For example, Even though the forecast improved, the trip was cancelled describes a known situation rather than a hypothetical possibility.
The worksheet also covers future conditional clauses, helping students avoid ordinary future will after these linking expressions. Students practise using the present simple or present perfect for future reference, clause order, comma placement and choosing expressions according to meaning rather than simply memorising structures.
The PDF includes a grammar focus section, choose-the-best-form practice, sentence-to-meaning matching, mistake correction, controlled sentence completion, rewriting tasks, meaning-and-structure practice, speaking questions, sentence-writing practice, integrated grammar production, an error-checking challenge, useful reminders and a full answer key.
This worksheet is suitable for one-to-one lessons, group classes, online English lessons, adult ESL and EFL classes, advanced grammar revision, exam preparation, business English lessons, homework and independent study.
