现在分词做状语

Question

Though a little suspicious this time, the policeman gave him the same answer.
Though a little suspicious this time,是个让步状语从句,主语和谓语动词都被省略了.如果我把它改成现在分词做状语不知道对不对?
Being a little suspicious this time, the policeman gave him the same answer.

有人说 原句是省掉了being，可以这样理解吗？
谢谢

Answer 1

1. 该句采用了状语从句的省略语法，即：
Though a little suspicious this time, the policeman gave him the same answer.
= Though (the policeman was) a little suspicious this time, the policeman gave him the same answer.
省略的是从句的主语和be动词，后者并不一定是谓语动词。

再如：When sleeping at home last night, I heard a knock at my door.
= When (I was) sleeping at home last night, I heard a knock at my door.
规定如下：如果状语从句的主语是it或与主句主语相同，且从句谓语动词以be动词开始，则可以省略从句的主语和be动词。

另：原句并非省略being.

2. 楼主改正无误，即可以改成：
Being a little suspicious this time, the policeman gave him the same answer.

Answer 2

though 引导让步状语从句时常可倒装，引导的从句主谓语若是系表结构时，可以省略从句主语和be动词。若改为改成现在分词做状语，需注意时态，因为警察给出答案之前以前已经有所怀疑，而回答是过去发生的，因此主句应用过去的过去，即过去完成时
Having been a little suspicious this time, the policeman gave him the same answer

内容很多，请搜索“现在分词短语”和“过去分词短语”。
总的说来，现在分词做状语，表示主动和正在进行；过去分词表示被动和已经完成。

原句是同时省略了主语和was
