主句+状语从句的结构,状语从句前面可以加逗号吗?
比如You can't have seen him,since I went to an international conference with him.
since前面可以加逗号吗?
答
一般这样的情况都不加逗号的。一般都是状语从句放在前面，加上逗号，再加上主句的。
if it rains tomorrow, i won't there.
答
不可以 。 since放在前面，才有。Since I ...., you .....
I didn't go to school because I was ill.
Beacause I was ill, I didn't go to school. 同一个道理。
答
比如You can't have seen him,since I went to an international conference with him.
since前面可以加逗号吗?
答：一般不加,如有插入语,或主句较长,想歇口气,就可以加.
这个例句有误,since应改为for
since表示原因时,常放在主句的前面,译作‘既然’.
