Everyone is expected to obey the following rules. 希望大家遵守以下规定。
Scan the reading text and underline all the verbs in the passive voice. Then discuss with a partner why the passive voice is used.
was going to be tested out; to be harmed; was being looked after; was being offered; was not allowed; was being treated badly; to be discovered by her; was being completely transformed
The passive voice is used to focus on the person or object that experiences an action rather than the person or object that performs the action. It is used when we don't know the performer, or the performer is unimportant ( and therefore omitted ), or the performer is to be highlighted ( and therefore placed toward the end ).
