Question

in front of the gate of the park stood an old pine tree like an umbrella covering the entrance
这句话里面的covering是什么用法,在句子中充当什么成份.

Answer 1

本句用了倒装,相当于An old pine tree like an umbrella stood in front of the gate of the park,covering the entrance.
句中covering the entrance是现在分词短语作状语（表伴随）,因为主语an old pine tree 与cover逻辑上是主谓关系所以用了表主动地covering形式.
