The past tenses of the modal verbs MUST, CAN and CAN’T often cause problems, even for advanced students of English. I have heard some of my best students, who had already passed the CAE exam, use words like MUSTED, and I was not happy about it. That is why I try to teach this grammar thoroughly.
[showmyads] In this post I would like to share an infographic and additional exercises I use to teach this grammar point. I hope you find this post useful. Please don’t hesitate to share any of your materials on this topic. You can send them to my email: rotreklzdenek @gmail.com. Thank you.
