I am wondering in which context people stress the be in English grammar. Both Wiktionary and Wordrefence have a weak and a strong form in their dictionary : https://en.wiktionary.org/wiki/be#English and https://www.wordreference.com/enfr/be
I know that for example, the word has is used in strong form only when used negatively.
- /aɪ həv si:n hə/
- /aɪ hævnt si:n he/
But for the word be, I see no example where we could use it negatively. If someone could help
