as作为连词,在引导原因状语从句时,表示已知的原因或理由。与because相比,as所表达的原因通常更为显著或已为人们所知,且语气相对较轻。 1. 基本结构:as引导的原因状语从句可以放在主句之前或之后,用于解释主句动作或状态发生的原因。当从句放在主句前时,通常要用逗号与主句隔开。 2. 语气与because的区别:as引导的原因状语从句在语气上不如because强烈,更多时候是作为对主句的附加说明或补充理由。它强调的是一种已知或显而易见的原因。 3. 常见用法:as引导的原因状语从句常用于日常对话、文章写作等场合,用于提供简洁而明确的原因解释。 as原因状语从句的练习题 1. 填空练习 在空白处填入适当的连词,使句子完整。 * _______ it was raining, we decided to stay at home.
