It is______for all construction workers to wear protective gear when they are at the project site.
选项
A、mandator
B、mandate
C、mandatorily
D、mandatory
答案
D
解析
be动词is后是表语位置,所以名词(A)和(B),形容词(D)都有可能是正确答案。句中it是形式主语,不定式to wear…project site是真正的主语,for all construction workers是句中的逻辑主语。根据“所有建筑工人都强制穿戴保护装置”的句意可知,修饰真正主语to wear…project site的形容词(D)mandatory(强制的,义务的)是正确答案。在使用名词(A)和(B)时,和真正的主语形成同等的主格关系,将两个词带入到句中,意为“穿戴保护装置的是命令者”和“穿戴保护装置的是命令”,语义不通顺,所以不正确。作为参考,应该知道(B)mandate在当动词使用时,有“授权”的意思。
