原因状语从句
Henry must have stayed up last night, ___ he looks so tired and sleepy. A. for B. as C. though D. since
答案是A, 你知道为什么吗?
引导原因状语从句的连词通常有because /as /for /since/now that
for, as, since都可以引导原因状语从句。for(因为)所提出的只是对所谈内容的一种补充说明, 因此for引导的句子不能放在句首, for也认为是并列连词。另外, for引导的原因从句前要用逗号分开。
as(既然,因为), since(既然)和now that (既然)提出的原因是已经的, 或是句中不太重要的部分。since比as稍正式一点。
如:We had to walk all the way as we had no money for fares(车费)。 我们一直步行, 因为我们没有车费。
Since you don’t trust him, you should not employ him. 既然你不信任他, 你就不该雇用他。
本题中的从句主要是对主句的补充,并且前面有逗号分隔, 所以选A。
另外, because强调的原因是句子中最重要部分, 因为常放在句末, 不能用其它词代替;同时回答why引导的问句时也用because。
