In most western countries, on April Fool’s Day，people often play trick on each other; children especially have great fun.
A. a；a
B. the；the
C. 不填；a
D. a；不填

A. a；aB. the；theC. 不填；a(答案→)D. a；不填解析：考查冠词。第一空是固定词组paly a trick on=play tricks on作弄…；欺骗；第二空后的名词fun是一个不可数名词，have fun玩的开心；句意：在大部分西方国家，在愚人节这一天，人们经常相互捉捉弄，尤其是孩子玩得非常开心。故D正确。
