Infinitives after passives

Passive verbs are sometimes followed by infinitives and occasionally by -ing forms. In this post we look at some examples.

1. Verb + object + infinitive

2. Infinitives after wh-words

3. Infinitives of purpose, etc

4. Infinitive forms

5. Passive reporting structures

6. Passives after preparatory it and there

7. Actions after verbs of perception - see, hear etc

8. Bringing it all together.

1. Verb + object + infinitive

In active sentences some verbs follow the pattern:

subject + verb + object + to-infinitive

The receptionist told me to wait.

They made him take a test.

In most cases these can be made passive. In the passive, all verbs (including make) are followed by to + infinitive.

subject + passive verb + to-infinitive

I was told to wait (by the receptionist).

He was made to take a test.

Verbs used like this include advise, allow, ask, expect, instruct, make, mean, order, require, teach, tell

Note 1. - let is not used this way in the passive; we need to use allow instead.

We were let to stay up late

We were allowed to stay up late.

Note 2. - some verbs followed by an infinitive in active sentences are not used in the passive - like, dislike, hate, prefer, love, wish, etc.

2. Infinitives after wh-words

These structures usually come after active verbs, eg - I don't know who to ask, but sometimes occur after passives, especially with tell and show.

We were told where to go.

They were shown what to do and how to do it.

3. Infinitive of purpose etc

We can also use an infinitive to mean in order to or something like so that. These are usually in the active, but passives are also possible.

He was selected to represent his country.

It has been designed to withstand high temperatures.

The bushes were planted there to hide the rubbish bins.

4. Infinitive forms

So far we have only used the standard to-infinitive, but Passive verbs can be followed by a to-infinitive in various forms. See if you can remember them:

Exercise 2

Enter the six forms of the to-infinitive of the verb do.

standard	We were told it immediately.
continuous	He is thought it right now.
perfect	She was meant it already.
perfect continuous	They are thought it for hours.
passive	The task is scheduled before the end of the week.
passive perfect	The job was reported rather well.

Notes: .

Perfect infinitives are used for actions that happened before the reporting

Passive perfect infinitives are sometimes used to emphasise that something is or isn't complete - It was to have been done today, but they didn't manage.

5. Passives followed by an infinitive - reporting verbs

In active sentences reporting verbs usually follow the pattern:

subject + reporting verb + that clause

They believe that the tourists are safe.

They reported that the suspect was dangerous.

In the passive, these verbs follow the same pattern with a to-infinitive as the causative verbs we've just been looking at.

subject + passive verb + to-infinitive

This pattern is used with verbs such as say, believe, feel, consider, know, report, think, understand

Exercise 3

Enter a suitable verb in the appropriate form of the infinitive. Each infinitive is in a different form.

arrive ·
injure ·
look for ·
plan ·
release ·
unveil

1.	Apple are expected their new iPhone next week.

6. Structures with preparatory it and preparatory there

There are two other structures used with reporting and similar verbs:

it + that-clause
It is said that

there + to-infinitive
There are known to be

You can find out more about these, and practise with some exercises, at my post on passive reporting structures (link below).

7. Actions after verbs of perception and certain other verbs

There are a couple of structures that can be used after verbs of perception, such as see, hear etc. We can use an -ing form to suggest that something was in progress, or a bare infinitive to suggest that the person witnessed the whole action. Notice what happens to these in the passive.

Subj + verb perception + obj + -ing form

She saw a man climbing out of a window.

A man was seen climbing out of a window.

Subj + verb perception + obj + bare infinitive

They heard someone shout a warning.

Someone was heard to shout a warning.

Notice the change to a to-infinitive in the passive infinitive version. In practice, only see, hear and observe are used much in the passive.

There's also a small group of verbs used in a similar way, but that are used only with the -ing form - catch, discover, find, keep (sb waiting), leave (sb doing sth)
