About this lesson
In this lesson you will learn how to make assumptions and deductions about the present using modal verbs such as must, can't, could, may and might. You will understand the difference between strong certainty (must / can't) and a weaker assumption (may / might / could). You will master the grammatical structures through an authentic dialogue and practical exercises. Through them you will develop the ability to speak and write convincingly, drawing logical conclusions in English.
