Using language
Past perfect passive
BY MICHELLE
01
Past perfect passive
Look at the sentences and answer the questions. Sentence (a) is from the reading passage.
a　At the start of the detox, over 100 students had been persuaded to stop using social media, in ANY form, for seven days.
b　At the start of the detox, people had persuaded over 100 students to stop using social media, in ANY form, for seven days.
Were the students in sentence (a) persuaded before the detox started, or afterwards
What is the difference between sentences (a) and (b)
Why does the author choose to use a passive form instead of an active form
The students were persuaded before the detox started.
They differ in voice. The passive voice is used in sentence (a), while the active voice is used in sentence (b).
Maybe the author doesn’t know who had persuaded students to stop using social media, or it is unnecessary to say who the persuaders were.
Now look for more sentences with the past perfect passive in the reading passage, and summarise its use in your own words.

Work in pairs. Describe the pictures using the past perfect passive.
Jack started the habit of cleaning his room last week. This is what his room looked like yesterday morning.
The floor was clean. The sheet was laid flat on the bed. All the books and clothes were placed neatly and tidily. The pictures on the wall were straight.
Work in pairs. Describe the pictures using the past perfect passive.
But two weeks ago, Jack's room was like this:...
Jack's room had been an awful mess. His clothes had been thrown everywhere; the pictures had not been hung straight; and all the drawers had been opened. It had been a very disorderly sort of room, with books and papers lying around everywhere.
