单选题 ______ I had lost his address, I did not know where I could find him.
A. Due to th at B. Owing to that
C. Due to the fact that D. Owing to the fact that

【正确答案】 D
【答案解析】四个选项都包含表示原因的短语，不同之处是A和B选项在短语后直接用that引导一个名词性从句，而C和D选项是先跟了一个名词，再跟一个同位语从句。如果知道在介词后必须接名词加同位语从句，那么就可将A和B先排除。C和D的区别在于位置。due to在句中可以充当状语或表语，但一般不置于句首，而owing to却可以置于句首，因此D为正确答案。
