Module 2《A Job Worth Doing》Period 3: FUNCTION—Making deduction about the past Objectives●To learn to making deduction about the pastProcedures▇Warming up by learning to “deduce”★Can we deduce from your silence that you do not approve?★We can deduce a lot from what people choose to buy.★The answer is deducible from the evidence available.★He arrived at the solution by a simple process of deduction.★If my deductions are correct, I can tell you who the killer was.★We can examine the bones of dinosaurs and make deductions about how they lived.■Making deduction about the past with modal verbs (degrees of certainty)As Swan (Practical English Usage (Oxford University Press, 1997)), explains:"One (of the meanings of modal verbs) is to do with degrees of certainty: modal verbs can be used to say for instance that a situation is certain, probable, possible or impossible. "Modal verbs can be used to express these ideas about the past, present and future.The most definite degree of certainty can be expressed with will and won't, followed by must and can't/couldn't, should and shouldn't, may and may not, and might/could and mightn't, which express the least definite degree of certainty.All of these modal verbs can be used to talk about degrees of certainty in the past. Once more, will or won't expresses the most certainty, and might/could or mightn't the least certainty. Examples:★That will have been Ted you saw --- he's seven feet tall.★It won't have been Sue you saw --- she's blonde and is five feet tall.★Notice that would and wouldn't can be used in the same way as will and would here:★That would have been Ted you saw --- he's seven feet tall.★It wouldn't have been Sue you saw --- she's blonde and is five feet tall.★That must have been fun --- you love dancing, don't you?It can't/couldn't have been much fun out on the boat --- there were gale-force wind, I hear. (See grammar definitions).★Where can they be? They should have been here a long time ago.★Where can they be? They shouldn't have taken this long.★She may have dropped by --- we were out all morning.★She may not have been able to see properly in the heavy rain.★He might have had an accident!★She mightn't have even known we were going to be here.★I'm absolutely sure!. They must have arrived yesterday, I saw their ticket.★Are you joking! David can't have gone to Paris last week. He doesn't have enough money.★The concert must have been wonderful last night. Fiore is a great conductor.★John isn't here. He's on assignment in Bali. So the person you spoke to this morning can’t have been John.★She might have taken the bus.
