40 questions to practise will for predictions and opinions: opinion markers (I think, I believe), probability adverbs (definitely, probably, maybe), and choosing the right prediction form.
Choose the correct option to complete each prediction. Opinion markers like 'I think', 'I believe', 'I doubt' are followed by will or won't. Correct answers are mixed across the set.
| Marker | Meaning | Example |
|---|---|---|
| I think | personal opinion, moderate confidence | I think he'll pass. |
| I believe | stronger personal opinion | I believe it will work. |
| I'm sure | high confidence | I'm sure she'll be fine. |
| I doubt | negative opinion (use 'will' after!) | I doubt he will come. |
| I don't think | negative opinion (better than 'I think ... won't') | I don't think it will rain. |
| Adverb | Probability | After will (+) | Before won't (−) |
|---|---|---|---|
| definitely | ~95% | will definitely come | definitely won't come |
| certainly | ~90% | will certainly pass | certainly won't pass |
| probably | ~70% | will probably rain | probably won't rain |
| perhaps / maybe | ~50% | will perhaps try | perhaps won't try |
