最好有解析

Answer 1

C 固定结构
B as因为
as，because，since都可以表示因果关系，连接原因状语从句，含义是"因为，由于"，但它们有区别：because表示的语气最强；as一般放在句首，语气较弱，较口语化；since常常用在书面语中，表示多为对方已知的、或稍加分析便可得知的原因，有时可译作"既然"。例如：

(1) He will succeed because he is in earnest.他一定会成功，因为他很认真。

(2) Since you are so sure of it he”ll believe you.既然你对此如此有把握，他会相信你的。

(3) As rain has fallen, the air is cooler.因为下过雨，空气比较清爽。
