Tasting nice and delicious, the roast ducks

1. 非谓语动词短语做状语,一般考查该动词和主语的关系(特殊情况例外).
2. 句中主语是the roast duck,它和动词taste的关系应该是:
the roast ducks tasted/tastes nice and delicious
因为此处taste是个系动词,所以应该是主动/主谓的关系,所以用现在分词
3. 如果主语和该动词是动宾/被动的关系,则一般使用过去分词做状语.
如: Taken good care of by his mother, the boy is growing up healthily.

那烤鸭味道很好,很可口.
