Complete these sentences using the verbs in brackets in the passive voice. New programmes ________ (to introduce) by TV people all the time.

The passive voice is formed using a form of the verb "to be" + past participle. Since the sentence refers to "all the time," which implies a habitual or ongoing action, we need to use the present simple passive.

"New programmes" is plural, so we use "are". The past participle of "introduce" is "introduced". Therefore, the correct form is "are introduced".

Answer: are introduced
