To review the passive voice
① It was going to be tested out by Larry's wife, Claire.
② Now she was being looked after by a robot that looked so human, and it was disturbing.
③ Claire thought it was ridiculous that she was being offered sympathy by a robot, but she gradually admired his wisdom and integrity and began to trust him.
Scan the reading text and underline all the verbs in the passive voice. Then discuss with a partner why the passive voice is used.
④ As he was not allowed to accompany her to the shops, he wrote out a list of things that he would need for his work on the house.
⑤ Tony expected that the house, which was being completely transformed, would be ready.
⑥ The saleswoman there was rude to her, so she rang Tony and told him she was being treated badly.
Using the passive allows the speaker or writer to make choices about what is important.
We use the passive for different reasons. We sometimes use it to give focus to something. We can also use it because we don’t know the identity of the ‘doer’ or because it’s not important to know who or what did the action. In addition, we use it to be impersonal and create distance.
We often use passives without agents in academic and technical contexts when the process or actions are more significant than who or what did them:
e.g. A sample was taken and injected into a tube.
In this study, children’s eye movements were recorded while they listened to a series of messages.
We often use passive forms of reporting verbs (believe, think, say, consider, find) to create distance from personal statements and focus more on impersonal processes:
e.g. Police are looking for a man in his 30s. He is believed to be dangerous.
In some cultures blowing your nose in public is considered impolite.
When we want to give emphasis to something new, we can begin with something which is already known and put the newsworthy or important item at the end, where it can be stressed and given focus:
e.g. A: That’s a lovely chair.
B: Yes, it’s very old. It was given to me by my grandmother.
I was made to feel very welcome by everyone.
