25、b) 以 it 作形式主语，将 (a)中的动词变为被动态，保留(a)中的 that 分句；(c)将分句的主语变成被动句中的主语，将(a)中的动词变为被动态，再将 (a)中的 that 分句改为不定式短语，放在被动态后面。能这样用的动词主要有：think, consider, assume, suppose, say, report, acknowledge, feel, believe, find, presume, know, understand, etc.如果 that 分句的动词是进行体，这时分句要改为不定式进行体。They suppose that she is coming.
