37、the evening newspaper when a dog started barking.2 如不能和句子中的主语保持一致，该动词-ing形式必须有自己的逻辑主语，通常由名词或代词来担任。The last bus having gone,we had to walk home.Weather permitting,the football match will be played on Friday.,高中阶段有一些固定的动词-ing形式短语，如generally speaking,judging from.,considering.,talking of.,supposing.等，它
