ing和ed的问题比较麻烦高分求助好像是关于非谓语动词
先举两个选择题：

A:Dressed B:To dress C:Dressing D:Having dressed
_______from heart trouble for years,Professor White has to take some medcine with him wherever he goes.
A.Suffered B.Suffering C.Having suffered D.Being suffered
请先说明选择答案,并说明为什么,还有什么时候应该用“ed”,什么时候用“ing”什么时候用“having + ed”什么时候用“to”什么时候用“being+ed”.请认真回答.
就是zyyfaith同学说的，第一题选择A。什么时候用doing呢？

1.A dress 是给某人穿,要是人做主语就要用be dressed in
2.C 因为后面有for years,表示持续的一段时间,所以要用完成时,suffer用主动语态.
判断用ing还是用ed,主要看句子里的动词与主语的关系是主动还是被动,主动就用ing,被动就用ed.
being ed 表示正在被...例如：the building being built will be finished next month.

1.A 做he的定语
2.D 因为用的是被动语态Be+Ving
ed:过去时态时用动词+ed
ing: 现在分词时动词+ing
having+ed: 过去完成进行时用having+V+ed
to:动词不定式用to+V
Being+ed:名词化被动语态用Being+Ved

我感觉应该选A和C
1.be dressed in 是固定搭配
这个句子的完整形式应该是When he is dressed in a white uniform,he looks more kile a cook than a doctor.从句和主句的主语一致，我们可以同时省略从句的主语和be动词,when也可省略。 或者可以解释为he与dress是被动关系，应该用过去分词...

我感觉应该选A和C
1.be dressed in 是固定搭配
这个句子的完整形式应该是When he is dressed in a white uniform,he looks more kile a cook than a doctor.从句和主句的主语一致，我们可以同时省略从句的主语和be动词,when也可省略。 或者可以解释为he与dress是被动关系，应该用过去分词
2.首先我们说for years 表明这个句子时态应用完成时态，所以这个句子的完整形式是：
Because he has suffered from heart trouble for years,Professor White has to take some medcine with him wherever he goes.
这里he与suffer from 是主动关系，所以用动名词。
主语跟动词的关系是主动的时候就用doing
被动时用done
