Goal

It’s time to learn about how to make deductions by using modal verbs.

You can watch the video or go straight to the written explanation. You decide! Once you’ve finished, you can move to step 4.


Language Discovery


Look at the phrases in blue in the text in step 1. What do they have in common?

1- They all include modal verbs (might, must, can’t)

2- They all have a verb in the base form.

3- They are deductions.


Modals of Deduction

  1. It must run in the family.

She must be a little sleepy.

  1. She can’t be hungry because I fed her less than an hour ago. 

She can’t be very happy about having a dirty nappy.

  1. She might need to burp.

Yes, it might be from work.

We often use modal verbs when we are speculating or making deductions about things. Remember modal verbs are followed by a base verb:

It must run in the family

NOT It must runs in the family 

  1. must We feel sure that something is true because there is lots of evidence.
  2. can’tWe feel sure something is not true
  3. might /may/couldWe use might/may to say that we think something is possible but we’re not sure. We can also use could in affirmative sentences.

Dig a little deeper

The opposite of must is can’t, NOT mustn’t.

We often use be + gerund after might / must / can’t

Conclusion

Ready? Terrific! Let’s move on to step 3 to practise what you’ve learnt in this step.
