问题描述：
The young college students jumped into the river and swam to the boys___they heard them crying for
elp.
A as soon as B before C because D till
可为什么C不能填?
“年轻的大学生跳到河里游向男孩们因为他们听到了他们的哭救”也很顺啊
一定要透彻,并说一下语法和规律,
答
1. 语法情景题.强调一听到就跳下水.
2. 从汉语上讲：然跳下水的确是因为听到呼救了.但是呼救不是跳下水的直接原因.因此此处如果要表示原因,最好用for
3. for是并列连词,表示推断的原因,或对前一分句补充说明理由.
例：It must be morning for the birds are singing.一定是清晨了,因为鸟儿在叫.（鸟叫不是天亮的原因）
4. 其实A的确是最佳答案.
