Please note: The MARS / WARS and FADS sessions are back on Skype for another week, but a couple of Lynne's sessions have been cancelled. Check the calendar for dates and times.
Shiva asked in the lessons about the difference between could and could be.
Could is what we call a modal verb:-http://www.learnenglish.de/grammar/verbmodal.html
Click on the link and you will see it can be used in a variety of ways, and that could be why people get confused.
Did you see what I did there?
"Could be" can be used to express the possibility of something being true (or not).
For example: This could be the next forum.
It can also be used to describe the way something / someone behaved in the past:-
For example: As a child I could be a pain in the neck. / My first computer could be very temperamental.
Shiva, if you read this, the best thing to do now is practise a few sentences here.
