选项
答案calling改成called
解析 此处语法点是动词的过去分词作后置定语，它其实是由定语从句缩略为形容词短语的。这个句子可还原为：…workers to wear small computers，which are called "electronic tags"通常从句是被动语态时可省略关系代词(此处是which)和be．原文的动名词形式(calling)通常用于两种情况：一是表动作正在进行，二是表主动。这里small computers不能自己称自己为“electronic tags”，而应是被称为，所以应改成过去分词。动词的过去分词和ing形式各自的用法容易搞不清楚，也常考。
