这个英语句子存在语法错误吗?
I was walking on the street one day,then saw you I didn’t know what to say.
不是让重新改句子，请指出语法错误。比如：then 后边没有主语I
答
错误是一个句子中有两个动词,这样会好些:
One day,I was walking on the street .Then ,I saw you ,but didn’t know what to say
答
这句话，存在很大的语法错误！
正确的句子应该是这样：
I was walking on the street when I saw you that day,but I didn’t know what to say
按照你的意思，不应该用“one day”，应该用“that day”
意思是，那一天我遇到你，但不知说什么！
曲解你的意思，请你谅解！
答
有点问题,应该是：I was walking on the street one day.Then I saw you ,but I didn't know what to say.一楼的句子少成分,“not knowing what to say”少主语还有二楼的“I was walking on the street when I saw ...
答
Walking along a street one day, I saw you, not knowing what to say.
