Rob and Stephen look at how ‘must’, ‘could’ and ‘perhaps’ can be used to speak about certainty and possibility.


Watch the video. Then go to the Tasks and do the activities.




hello, could you help me with this please
"We could be looking for a tea drinker". Why do we use could be v-ing here. How about "we could look for a tea drinker" instead? Thank you.

Hello quoc hung,

Since Ashlie and Stephen are already investigating the crime when she says this, the continuous form is the best form here.

I am so interested in English after watching the video. It's very helpful.
Thanks a lot:).

I cannot find the video. Where is it?

Hello haq,

I've checked the page and video and both are working properly. If you still can't see it, I would suggest that you try using a different web browser or different device to view this page. That should solve the problem, I think, but if not, please let us know what browser and browser version you are using and we'll see what we can do to help you.

All the best,

I switched my browser from IE to Firefox and now I can see the video. Thanks for the help.

Hi Team.
Help me with these, please?
- Maybe someone shot her.
- The murderer might be close.
Is it nature if we put 'might' at the beginning of the sentence?
("Might be someone shot her").
- Just as I suspected,
- Just as I was about to say,
Do we always use 'just as' with the past form combination?
Would you like to explain, please?
Thank you very much.

Hello Nizam,

Yes, you can say 'Might be someone shot her', which is an informal and reduced way of saying 'It might be that someone shot her'.

As far as I know, there are no restrictions on the verb tenses that 'just as' can be used with. It is certainly very common, as you have already noticed, with the simple past in situations just as the one your example is from. But you could also use it when talking, for example, about a plan for a surprise birthday party, 'We'll all sing 'Happy Birthday' just as she turns on the lights after getting home'.

All the best,
The LearnEnglish Team

Thank you
