Mr. Brown told his son that ______ . [A] he would be away from home for four days [B] he would be back in seven days [C] he would be back in a month

B
【答案解析】[精解] 题干的意思是Brown先生告诉他儿子什么。A的意思是他将离开家四天，B的意思是他七天内回来，C的意思是他一个月内回来。文章第一句为“Mr．Brown was going away for a week．”，即Brown先生将要出门一周，可以推断为七天之内可以回来。因此B是正确答案。
