Passive verbs

Introduction

In spoken English we often use a subject such as "people", "somebody", "they", "we", or "you" even when we do not know who the agent is. In formal English, particularly writing, we often prefer to use a passive.

Compare:

They're installing the new computer system next month.
The new computer system is being installed next month. (more formal)
