Download this free B1–B2 grammar worksheet PDF for English learners and teachers. This lesson helps students practise the zero conditional, the first conditional and future time clauses with when, after, before, as soon as and until.
Students learn how to use the zero conditional for general facts, routines and repeated results. The worksheet gives clear examples such as If I don’t sleep enough, I feel tired and When I work late, I take a taxi.
The worksheet also teaches the first conditional for real future possibilities and likely results. Students practise forms such as If the weather improves tomorrow, we’ll eat outside, If the train is late, we won’t arrive by six and What will you do if the client cancels?
Students also learn how to use future time clauses correctly. The worksheet explains that after when, after, before, as soon as and until, students should normally use a present form for future reference, not ordinary future will. Examples include I’ll message you when I arrive, I’ll wait until he arrives and As soon as the results arrive, we’ll publish them.
The worksheet also covers key B1–B2 nuance. Students practise the difference between when for general repeated situations and when for one future event, clause order and comma use, negative main clauses with until, and present perfect in time clauses, as in I’ll send the file when I’ve checked it.
The PDF includes a grammar focus section, zero conditional and first conditional exercises, choose-the-correct-form practice, sentence matching, mistake correction, mini-dialogues, sentence rewriting, meaning-and-use practice, speaking practice, writing practice, vocabulary and grammar sentence practice, an error-checking challenge, useful reminders and a full answer key.
This worksheet can be used in one-to-one lessons, group classes, online English lessons, adult ESL lessons, EFL classes, exam preparation, homework or independent grammar practice.
