Because her son is interested in reading,she often buys books for her son.
怎么样把这个缘由状语转化为独立分词结构呢？
Her son being interested in reading,
Her son interested in reading,
不知哪一种改法正确？这个being在这样的情况下，到底是去还是不去？或者说interested这个词非常特殊，和其他分词作状语不同？按道理说理解为被动结构我也没错吧？
假如这里不去这个being的话，岂不是其它被动结构也可以不去掉这个being了吗？望指教
Because her son is interested in reading,she often buys books for her son.
用以下两种形式的独立主格结构，都正确。
Her son being interested in reading, she often buys books for him.
Her son interested in reading, she often buys books for him.
下面是针对分词作状语的解答，同样合适于独立主格结构：
1. 单个的形容词作缘由状语，这个时候应加being，变成非谓语动词，即：目前分词。非谓语动词作状语很自然。
比如：
Being ill, he can’t attend today’s meeting.
Being hungry, they had to look for food.
2. 若是分词形容词（由过去分词变来的形容词），加不加 being 均可，由于它过去是分词，本身就是非谓语动词。
比如：
worried about his health, she couldn’t sleep.
surprised at the news, he kept asking how.
3. 若是形容词词组作缘由状语，加不加 being 均可。比如：
seriously ill, Tom couldn’t go to school.
sad over the news, she cried all day.
个人怎么看：语言追求简练，但也应防止单调。单个的形容词之前加 being，主如果为了防止单调。一个形容词读起来会很唐突，像 ill 和 angry。如果是Being ill，Being hungry 则非常自然。
