分词的时态问题
Seeing the teacher is coming, the students stopped playing.is 能不能改成 was?句子能不能改成 Seeing the teacher was coming, the students has stopped playing.(语法问题上有没有错误）

Answer 1

原句有错误Seeing the teacher is coming, the students stop playing.或者是Seeing the teacher was coming, the students stopped playing.应保持前后时态一致. seeing在这里是连词 意思是 因为, 既然, 鉴于例如seeing that因为...; 既然; 鉴于Seeing (that) he refused to help us, there's no reason why we should now help him.他既然曾经拒绝帮助我们, 我们现在没有理由要来帮助他.
