Manner and Purpose Phrases - Advanced Exercises

Advanced manner and purpose phrases ask you to notice fine differences between expressions that can look similar. Key phrases include by accident, by chance, on foot, at random, on purpose, in a hurry, by heart, in vain, and by mistake. The contexts are less direct than in easier practice, so the best answer depends on whether the sentence shows intention, luck, error, memory, wasted effort, rushing, random selection, or walking.

The key distinction is often between unplanned events and errors. By chance means through luck or coincidence, as when you meet an old teacher unexpectedly. By accident means unintentionally, especially when something goes wrong. By mistake points to a wrong choice or confusion. At random describes selection without a pattern, while in vain says an attempt failed. These phrases help B2 learners sound precise in narratives, explanations, and formal descriptions. Small context details, such as luck, blame, selection, or failure, decide the answer accurately here.
