    the light is refracted by the surface of the glass.
    2.2. pseudo-passive
    another passive form is “pseudo-passive”. it is considered as passive. because the predicate of pseudo-passive is “be+-ed”. it is impossible that pseudo-passive can be transformed into active voice. “be” in pseudo-passives can be replaced by “become, feel, remain and seem”. the past participles can be modified by “very, quite, more and rather.” the participles in pseudo-passive don’t have the characteristics of verbal-participle. it just becomes an adjective.
    for examples:
    my uncle was (got or seemed) (very) tired.
    the car was old and ruined.
    the agentless passive sometimes is regarded as “subject + copula + predicative”.
    2.3. quasi-passive
    2.3.1. quasi-passive also call semi-passive. it is between true-passive and pseudo-passive. the –ed participles in quasi-passives can express the characteristics of verbal-participle and adjectival-participle. this structure can be transformed into active form. it also can be modified by “very, quite more and rather”. “be” in quasi-passive can be replaced by “feel, seem, become and remain”.
    for examples:
    i was alarmed by the news.
    → the news alarmed me.
    → i was alarmed by and angry at the news.
    → i was very alarmed by the news.
    → i felt alarmed by the news.
    she was irritated by these two children.

    → she was more irritated by this child than by that.
