Chapter II theoretical background of the categories of the verb

Gerunds and nominalization
Gerunds and nominalized verbs (nouns derived from verbs and referring to the actions or states expressed by them), unlike finite verbs, do not require explicit subjects. This allows an object to be expressed while omitting a subject. For example:
The proof of the pudding is in the eating.
Generating electricity typically requires a magnet and a solenoid.

Many English educators and usage guides, such as The Elements of Style, discourage the use or overuse of the passive voice, seeing it as unnecessarily verbose (when the agent is included in a by phrase), or as obscure and vague (when it is not). This perception is exacerbated by the occasional intentional use of the passive voice to avoid assigning blame, such as by replacing «I made mistakes» with «Mistakes were made.»
Nonetheless, the passive voice is frequently used for a number of other reasons:
Certain verbs frequently appear in the passive – for example, be born, be smitten, and be had are all more common in certain senses than their active counterparts – though in many cases these might be better analyzed as adjectival passives (see above) than as true passives.
The passive voice serves to emphasize the patient; if the agent is comparatively unimportant to the point, or if the agent is obvious from context, then the passive voice might serve a rhetorical purpose.
Since in English, the subject nearly always comes before the object in a sentence, using the passive voice (i.e., promoting the patient from object to subject) moves the patient earlier in the sentence. If the patient has been mentioned in a previous sentence, this can serve as a marker of the connection between the two sentences.
Scientific writing has traditionally used the passive voice rather than mentioning a researcher in every sentence; this may be changing, however.
In journalistic writing and law, two areas where it can be essential to state only established facts, use of the passive voice allows uncertain agents to be omitted; again, however, use of the active voice is on the rise, with other mechanisms being used to avoid insupportable claims.
