with my head ( lower)用ing还是ed
with 结构中用-ed还是用-ing,取决于它与前面的名词、代词之间的关系,如果它与前面的名词/代词之间是主动的关系,就用-ing形式；如果是被动关系,就用-ed形式.
此处的bow与前面的head之间是被动关系,头被低下,所以用-ed形式.
如：
with the door closed
with all the people looking at him那lower呢用ing还是ed只要是前面的名词与其后面的动词之间是存在被动的关系，用法是一样的。lower是及物动词，头是被低下的，with his head lowered顺便看看下面的句子，也许对你有帮助1.with+ 宾语+ 过去分词1) With his key lost, he couldn’tget into his house.(钥匙丢了, 他进不了家门. )2) With his hair cut, Father looks much younger.
