as引导时间状语时不可省

你说那个是这样的：
while walking along the street last night, I heard a voice and felt very scared.
While walking along the street, I met an old friend of mine.
当状语从句的主语和主句的主语一致的时候，可以把状语从句的主语和系动词一起省略。但是一般不是在since引导的状语从句中哦。

1. since从句的谓语动词是终止性动词照字面意思理解。如：

I’ve been feeling down since I lost my job. 自从失去工作后,我的情绪一直处于低潮。
2. since从句谓语动词延续性动词，且为现在完成时时，仍然按字面意思理解。如：
She has never come to see me since I have lived in the city. 自从我住到城里，她就一直不来看我。
3. since从句谓语动词延续性动词，且为一般过去时时，按与字面意思相反的意思理解。如：
I have made great progress since I was ill. 我自病愈以来取得了很大的进步。
4.since前有ever，或从句谓语动词是be且后接表示人成长过程中的某个阶段或年龄的名词、形容词时，仍然按字面意思理解。如：
I have lived here ever since I was a child. 我从还是个孩子时就一直住在这儿。

可以,但是，结构和表达搭配要正确。例如
They have been good friends since they met last Sunday.
=They have been good friends since their meeting last Sunday.

可以省略
