A.Having seen B.Seeing.请老师详细解析句子结构

Answer 1

解析过程：
选A.句意：尽管他以前看过这部古典电影, 但是他仍然决定和他的女朋友再看一遍.
根据before以及句意, 可以知道动作see发生在谓语动词decide之前, 再根据he和动词see成主动关系, 所以用现在分词的完成主动式, 因此选A.
Having seen the classic film before , he still decided to see it again with his girlfriend.=Though he had seen the classic film before , he still decided to see it again with his girlfriend.

规律方法：
对于非谓语动词的选择, 1 首先看非谓语动词是做状语, 定语还是宾语补足语； 2 其次找非谓语动词的逻辑主语, 如果作状语, 逻辑主语就是句子的主语, 如果作定语, 逻辑主语就是前面被修饰的名词； 如果做宾补, 逻辑主语就是前面的宾语. 3 如果逻辑主语和非谓语动词成主动关系, 就用-ing形式, 成被动关系, 就用-ed形式. 4 最后看非谓语动词和谓语动词的时间先后, 如果发生在谓语动词之前, 往往用现在分词的完成式having done或having been done结构.
