Question

—Tony misses his hometown very much.

—Yes, he       from his hometown _____he was twenty years old.

A. has been away; for

B. has left; since

C. has been away ; since

Answer

C

【解析】

试题分析：句意：――托尼非常想念他的故乡。――是啊，他从二十岁就离开了故乡。从二十岁离开故乡到现在，表示过去开始一直延续到现在的动作或状态，用现在完成时态；离开：leave，是一个非延续性动作，不能与for,since连用，把它改成be away；he was twenty years old（他20岁）是时间的起点，用since引出时间的起点（for引出时间的长度）。故选C。

考点：考查现在完成时及连词的用法。
