问题 All bags and briefcases______into the building are subject to inspection.
选项 A、bring
B、brought
C、are bringing
D、have brought
答案 B
解析 因为句子的动词是are，所以空格中不能填入动词。因此可以单独作为动词结构使用的(A)bring，(C)are bringing，(D)have brought都不是正确答案。bring的过去分词形式brought表示被动的含义“被带进来的”修饰主语All bags and briefcases。空格前面的which are可以省略。
