语气的种类:英语句子中谓语动词的语气有四种:1. 直陈语气(the indicative mood)直陈语气用于直截了当地陈述事实、描述状态: e.g. he has published quite a number of essays this year .他今年已发表了好几篇论文。2. 祈使语气(the imperative mood)祈使语气用于提出请求、命令、建议或是劝告等: e.g. wait outside until you are asked . 请在外面等候,请你进再进去。 let"s just take a break, shall we ? 我们休息一会儿,好吗?3. 疑问语气 the interrogative mood :用来提出问题 e.g. where are from ? 虚拟语气(the subjunctive mood)虚拟语气用于表示主观愿望和假设的虚拟情况。虚拟语气不太顾及事实的存在,它表现出说话人的主观因素比较多。所以说话人所讲的内容往往是与事实相反的;或是其实现的可能性微乎其微,甚至于没有实现的可能性。当然,有时为了使说话的语气客气、缓和、委婉,也使用虚拟语气。e.g. i wish you were more careful .但愿你更细心一些。if i had more money, i would buy a bigger apartment.
