Converting reported speech with infinitive to passive: original “He told me not to touch it” becomes “I was told not to touch it by him.” Structure: object (me) becomes subject (I) + was + past participle (told) + infinitive phrase (not to touch it) + agent (by him). The negative infinitive “not to touch” remains intact. This passive form focuses on the recipient of the instruction.
