Look at the underlined words in the tapescript🤯It’s completely contrary to my grammar rules that the verb BE is followed by a verb instead of a present participle or an infinitive. Please tell me why, thanks! As the dictionary says, we can use “what” as a pronoun to mean “the thing(s) that”. So these sentences can be transformed to: The thing(s) that you do is send it to me … The thing(s) that I do is keep in touch with you … The thing(s) that you can do is phone them up … The thing(s) that you can’t do is leave it … We get rid of the clauses then: The thing(s) is send it to me … The thing(s) is keep in touch with you … The thing(s) is phone them up … The thing(s) is leave it … These sentences seem grammatically incorrect, don’t they? What if I change these verbs to “sending/keeping/phoning/leaving” or “to send / to keep / to phone / to leave”? Are they accepted usages?
