Electronic business transactions ______(conduct) in full or in part in a wireless environment are referred to as mobile commerce.
Electronic business transactions ______(conduct) in full or in part in a wireless environment are referred to as mobile commerce.
【正确答案】:conducted
【题目解析】:一个句子中只能有一个谓语动词,由于句中已经有谓语动词are referred to,所以前面要用非谓语动词。transaction(交易)与conduct之间是被动关系,所以用过去分词。
