主动语态转换为被动语态
在将主动语态转换为被动语态的过程中，应注意以下几种结构不同的转换方式。
a. 主语 + 谓语 + 宾语
这类结构转换成被动语态时，把宾语转换成主语，主语转换为“by + 宾语”的短语，谓语动词转换为被动结构。如：
Susan bought the flowers just now.
→ The flowers were bought by Susan just now.
苏珊刚刚买了花。
b. 主语 + 谓语动词 + 间接宾语 + 直接宾语
这类结构转换时，既可将间接宾语转换成主语，
也可将直接宾语转换成主语。如：
Mr Green gave the children some cards.
→ Some cards were given to the children by Mr Green.
→ The children were given some cards by Mr Green.
格林先生给那些孩子一些卡片。
