 GWD-23-Q23

After several years of rapid growth, the healthy care company became one of the largest health care providers in the metropolitan area, while it then proved unable to handle the increase in business, falling months behind in its payment to doctors and hospitals.

A.    while it then proved unable to handle the increase in business, falling months behind in its payment to

B.    while it then proved unable to handle the increase in business and fell months behind in its payment to

C.    but then it proved unable to handle the increase in business, falling months behind in its paying

D.    but then proving unable to handle the increase in business, falling months behind in paying

E.     but then proved unable to handle the increase in business, falling months behind in paying

我选了A，答案是E

关于E：1 paying优于 payment?

            2 “ ,BUT” 不是只能连接句子么？

       3 感觉while也是表对比阿

问题1 payment for sth./sb.

问题2http://forum.chasedream.com/dispbbs.asp?boardid=23&id=324770&star=1#2939294 有讨论

问题3 while 和but 都没错，A错在it主语指代the healthy care company ，但while句后根据逻辑关系应该用被动。少了was

非常感谢raiden_lee 

关于问题3，如果选择E，那么proved 仍然不是被动阿

你的问题很好，也是我的问题。我认为E中proved 前省略了the healthy care company became

并借用BY的理论证明

两个句子并列,第一个句子含有be动词或者become,第二个句子中的be动词或者become必须省略,同时,一些重复的名词或形容词也必须省略。例如:

Once the economic and social usefulness of the motor was demonstrated and its superiority to the horse proved, ... (proved前省略了was)

注意:be able/unable to是be动词短语,在这个短语中be动词不是助动词,不能省略！
        

例:A president entering the final two years of a second term is likely to be at a sever disadvantage and is often unable to carry out a legislative program.

望大家讨论

如果but作为连词后面省略的相同的主语和谓语the healthy care company became的话，
                but then the healthy care company became proved unable to handle the increase in business, falling months behind in paying那补全后proved作为什么成分呢？
