1) People say that this house is haunted.
全句分兩部份
People say = 主句
that this house is haunted =名詞子句 (haunted = past participle
used as adjective 作形容詞)
Main subject of the main clause is stressed 重點放在people
2) This house is said to be haunted.
this sentence has exactly the same meaning as the first one; but the emphasis is on the house, and therefore the verb after it is in passive voice.
第二句等同第一句, 重點放在屋, 所以用被動式
