表Conclusion连接词：that、whether连接代词：who、whom、whose、what、which、whoever、whomever、whatever、whichever连接副词：when、where、why、how注：that在主语从句中无实际意义，但不能省略。表语从句中that也不能省略。主语从句放于句首时不能用if引导，用it作形式主语时，也只能用whether引导主语从句。“nomatter+疑问词”不能引导主语从句，此时用“疑问词-ever”的形式引导。step5:it作形式主语为了避免头重脚轻，在主语从句中常用it代替主语从句作形式主语置于句首，而把主语从句置于句末。常用句型如下：1.It+be+名/形+that从句Itisapity/shamethathelostthegame.ItispossiblethatchairmanXiwillcometoGuizhou.2.It+vi+that从句Itseems/appears/happens/occursthat(似乎、碰巧)Itseemedthathewasangry.3.It+be+过去分词+that从句Itissaid/reported/wellknown/believed…thatItisbelievedthatMH370hasdisappeared.step6:当堂导练1.finish金太阳Unit4Period
