文档介绍：虚拟语气 ,所说的是一个条件,不一定是事实,或与事实相反。 ,一类为真实条件句,一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。真实条件句真实条件句用于陈述语气,假设的情况可能发生. 句型:条件从句+主句一般现在时+shall/will+动词原形 es,hewillbringhisviolin. 典型例题 Thevolleyballmatchwillbeputoffifit___. A. willrain 答案B。真实条件句主句为将来时,从句用一般现在时。注意: 1)在真实条件句中,主句不能用begoingto表示将来,该用shall,will. (错)Ifyouleavenow,youarenevergoingtoregretit. (对)Ifyouleavenow,youwillneverregretit. 2)表示真理时,主句谓语动词便不用shall(will)+动词原形,而直接用一般现在时的动词形式。非真实条件句时态:能够表示过去,现在和将来的情况。它的基本特点是时态退后。。句型:条件从句+主句一般过去时+should(would)+动词原形 Iftheywerehere,theywouldhelpyou. 。句型:条件从句+主句过去完成时+should(would)have+过去分词 Ifshehadworkedharder,eeded.
