Unit III revision

Task 7

Translate from English into Russian concentrating on the meaning of deduction while matching the items on the right to the items on the left.
We use various forms when we are making a deduction based on evidence or on our experience:
-He always wears smart suits. He could be a businessman.
-Why isn't she here yet?'- I don't know. The train may be running late.'
We can use well after may, might and could if we think the possibility is quite strong. If we are very certain of the possibility, we use must:
-He must be ill, otherwise he would be here.
