问题
Without a(n)________passport a tourist is forbidden to enter a country.
选项
A、operative
B、effective
C、valid
D、efficient
答案
C
解析
没有有效护照的游客禁止入境。形容词辨析题。这四个词都有“有效的”这个意思,但用法各有侧重。operative意为 “可使用的,有效的”,指法律、法规、规定等有效的;effective意思是“有效的,实际的”,指方法或措施有效,强调能达到预期效果;valid意为“(法律上)有效的,(正式)认可的”,通常指证件等合法有效的efficient意思是“效率高的;有能力的”,指人有能力或指方法有效。根据句意可知,C项为正确答案。
