reason用于事情可指“理由,原因,道理,情理”,用于人可指“理智,理性,思维能力,推理能力”。
reason后常可接动词不定式或for引导的短语或从句作定语,引导从句的why在口语中常省略。
reason作主语时,可接that引导的从句作表语。
引导the reason的定语从句,多数语法学家认为应是that,而章振邦和张道真两位先生却只给出why,实际上这两种都是可以的,许多语法书或辞书都有收录,故可放心使用。
传统的语法规则认为the reason...is because...句型是错误的,应将because改为that。但是,近些年来, the reason...is because...不仅在口语中,而且书面语也用得颇多,甚至得到了某些词典的认可。例如:The real reason people no longer wanted to be secretaries was because the pay was so low.人们不想当秘书的真正原因是工资太低。不过为了稳妥些,还是少用because为好。
v.(动词)reason的基本意思是根据事实作出判断或推理,强调连续的逻辑思考,以某个假设的前提、某个确定的数据或证据开始,作出推论。引申可指“争辩”。
reason既可用作及物动词,也可用作不及物动词。用作及物动词时,通常接that从句作宾语。
reason可接介词into表示“说服某人做某事”; 接out of表示“说服某人放弃某事”; 接out表示“推断出”; 接with表示“说服,规劝”。
