Learn about the use of Passive Versus Active + Causative verbs.
We often use the passive to describe a process or emphasize the action rather than who is doing the action. English grammar
Structure English grammar
The passive always contains: to be + past participle English grammar
The verb ‘to be’ can be conjugated in any tense: English grammar
- Present simple: am, is, are Present continuous: am/is/are being
- Past simple: was, were Past continuous: was/were being English grammar
- Present perfect: has/have been Past perfect: had been
- Future: will be With modals: can / could / must / would / should… be
- Modals in the past: could / should / would / must have been
The past participle for ‘regular verbs’ is ‘-ed’: ask -> asked
For irregular verbs, you need to check an irregular verb list; past participles are in the third column: write – wrote – written
- The fees were included in the contract.
- The prices will be written in the quotation.
- The operators have been asked to speed up production. English grammar
In the above examples, we don’t know who included the fees, who will write the quotation, nor who have asked the operators. This information is not considered necessary or important. However, it can be included if necessary by adding the ‘by’ after the past participle:
- One of the most famous social network companies was founded by a college drop-out. English grammar
Usage English grammar
The passive is used more commonly in writing especially in reports, textbooks, in industry, science and technology to describe processes, and for official rules. We use the passive in these cases because we don’t always know who the ‘agent’ is.
Compare the active and the passive in the following examples: English grammar
- People have used this application for a long time. This application has been used for a long time.
- You freeze-dry the reagent in the vials. Reagents are freeze-dried in the vials.
- Someone has to count the points at the end. The points have to be counted at the end.
Things to look out for on the TOEIC Grammar
> We sometimes use ‘get’ instead of ‘be’.
- They got lost on their way to the construction site.
- Do you often get asked questions about your unusual professional background?
> Don’t confuse the past participle (-ed or irregular form) with the present participle (-ing)
- I am interested in this article.
- This is an interesting article.
A present participle can be used to describe the feeling that a noun causes. The article interests me. The past participle tells us how the subject feels. We can substitute the verb ‘feel’ for the verb ‘be’:
- I was bored during the movie. (I felt bored.)
- That movie was really boring. (The movie caused me to be bored.)
Other verb pairs that can be confusing (or that make us confused!) :
- Jane told us an amusing/shocking/surprising story.
- We were amused by/shocked by (or at)/surprised at her story.
- The 10-day strike was annoying for the commuters.
- The commuters were annoyed about the strike.
Causative verbs are used to show that a person causes, makes or enables another person to do something or make something happen. The structure of these types of sentences can be confusing as the verb after the causative verb may be in either the infinitive without ‘to’, the ‘to-infinitive’ or the past participle depending on the causative verb used. On the TOEIC, you will need to understand these differences.
