非谓语动词做壮语，其逻辑主语要与句子主语保持一致

你的标题就是理论部分，一点错误也没有。但是你的例句就有问题了。 1. Arriving home ,the door was found locked. 是个错句 因为主语the door ，不能发出arrive-When I arrived home,the door was found locked. -Arriving home ,I found the door was locked 改写之后都是正确的。理论同上2. looking out of the window ,there are lots of people in the street. 这个也是错误的，理论同第一题-When you look out of the window,there are lots if people in the street. -Looking out of the window ,you can see there are lots of people in the street. 后面这2个都对。参考文献：个人观点 收起
