A、such
B、all
C、many
D、those
【正确答案】：A
【题目解析】：第31题考察的是英语中词汇的正确用法。句子中提到“It is widely used for 31 purposes as meteorological(气象的)and airport communications,international conferences,and the?32?of information over the radio and television networks of many?33.”，根据句子结构，这里需要一个能引导目的状语的词。 选项A的“such”在这里作为形容词使用，修饰名词“purposes”，意思是“这样的，如此的”，用于列举具体的例子，符合句子中列举“meteorological(气象的)and airport communications,international conferences”等用途的语境。 选项B的“all”通常用于表示“全部，所有”的意思，但在这个上下文中，它不能很好地引导并列举出具体的例子。 选项C的“many”虽然可以表示数量多，但在这里缺乏引导具体例子的功能。 选项D的“those”通常用作代词，指代前面提到的名词，但在这里并不适用，因为前面并没有提到需要被代指的名词。 因此，根据句子的结构和语境，正确答案是A，“such”。
