问题补充：

I don’t have to live in the hotel my friend provides a very good place for me.

A. because

B. if

C. until

D. because of

答案：

(答案→)A. because

B. if

C. until

D. because of

解析：because“因为”引导原因状语从句，if“如果”引导条件状语从句；until“直到…才”引导时间状语从句，because of“因为”后面应该接名词，代词或动名词等，不能跟句子。根据前后句的关系，本句应该用because，所以本题选A 。
