Question

一道英语选择题，帮我解释下

It's necessary to be prepared for a job interview. ______will certainly do you good.
A.Well dressed B.Well dressing C.being well dressed D.Well dressing from

选什么，并详细解释下为什么选这个，谢了！

Answer 1

选C，要填的地方是做主语，主语可以是名词，代词，或名词性短语，A中dressed可看做是adj，adj不可做主语。B中，dress一般用被动态，所以不行。D中，同B。所以选C。
PS：你应该好好复习一下名词性短语或从句这一块内容，之后这个问题就可以迎刃而解了

Answer 2

C

Answer 3

C
穿戴得体当然有好处。
being well dressed 是动名词做主语。

Answer 4

选C。
分析：A.well dressed 过去分词不能作主语，故排除A。
B.well dressing D.well dressing from 打扮，穿衣用be dressed up ，排除B、D，
选C.being well dressed
对比下面的题目：
