第一题选A没错,其他答案不好.分析如下：我闻到某个东西肯定是（正在燃烧）,强调有东西此刻在烧,你闻到味道了.如果选C,表示正在被（人）烧,表面看也行,但你怎么能闻到人呢?懂了吗?不懂继续问.所以,BCD都不好.
第二题是动名词的完成时,暗示或者强调发生在谓语动词（此题为were praised)之前的动作,即强调having finished这个动作是发生在were praised之前.可译为：我们因为（提前）完成工作而（之后）受到表扬.
再如：He seemed to have been hurt before.他似乎以前受过伤.（受伤先于seemed这个谓语动作）

Something is burning.
=> I smell something (that is) burning. 。。。。that is 被省略了。
2) praised for ... 后面自然是接动名词从句没错。
唯一你没列入考虑的，是 既然主句时态上用的是 were 那从句必然...

1.不用特别强调被烧！只是有东西在烧！
2.ahead of time 是提前的意思。有强调一种已经过去的状态！就用现在完成时咯！
