问个高中英语语法题
______,he remains in a bad mood.
A Although got a lot of money
B Having got a lot of money
C Although a lot of money got
D He has got a lot of money
ing可隐含让步之意 ,表达即使,即B项可以理解为前面相当于有个Although
请帮分析下A,C,D为什么错 尤其是A 不可以理解为Although (he)got a lot of money吗,不是说主从主语一样可以省略一个,我这语法不太清楚,为什么不能是Although后有个He省略掉了呢

Having got a lot of money,he remains in a bad mood.
A Although got a lot of money 语法不正确
Although 表示让步,可以有两种说法：
1）although + 从句,即 Although he has got a lot of money
2）although + 分词短语.即 Although having got a lot of money
后者等于前者去掉主语 he 后再把谓语动词变成分词 having got
B Having got a lot of money 是分词短语作状语,逻辑主语就是句子主语 he,语法正确.
注：句首的分词短语可以作时间、原因、条件、让步从句
C Although a lot of money got 语法不正确
Although 后不可跟独立主格结构,即“名词（主格） + 过去分词”,因此需要改为被动语态 Although a lot of money has been got.
D He has got a lot of money和后面的句子连接不正确
如果有两个单独的句子,需要通过下列手段变成一个相互关联的句子：
1） 用连词 but 或 yet 连接—— He has got a lot of money,but/yet he remains in a bad mood.
2） 用分号并列—— He has got a lot of money; he remains in a bad mood.
3） 用从属连词 although 连接——Although he has got a lot of money,he remains in a bad mood.
