分词作结果状语时,通常位于句子的主谓结构之后,且常常带有副词 thereby, therefore, thus 等,以示强调。如:
We increase the length of the wire, thus increasing its resistance.我们增加了导线的长度,从而增加其电阻。
He didn't come today, thereby making it necessary for us to find someone else. 今天他没有来,因此我们必须找别人。
不定式(短语)作结果状语主要用于一些固定句型,如“too...to”结构、“only + 不定式”、“so...as to do sth.”、“be such as to do sth.”、“such + 名词 + as to do sth.”等。
