+强调部分+that...  该句型是强调句型。将被强调的部分放在前面,其它部分置于that之后,被强调部分可以是主语,宾语,表语或状语,强调的主语如果是人,that可以由who换用。如果把这种句型结构划掉后,应该是一个完整无缺的句子;这也是判断强调句型与其它从句的方法。Itwasabout600yearsago_____thefirstclockwithafaceandanhourhandwasmade.Itwasthey___cleanedtheclassroomyesterday.+被强调部分+that...该句型也是强调句型。主要用于强凋时间状语,译成汉语"直到...才...",可以说是not...until...的强调形式。Itwas__________thatIrealizedshewasafamousfilmstar.’tshetakeoffherdarkglasses=Ididn'(obvious,true,possiblecertain....)that.....该句型中it是形式主语,真正的主语是that引导的主语从句,常译为"清楚(显然,真的,肯定...)" 是主语从句最常见的一种结构。Itisveryclearthathe'sroundandtalllikeatree.=Thathe'’(necessary,right,strange,natural...)that...该句型和上一个同属一个句型;由于主句中的形容词不同,that后的从句中要用虚拟语气(should+动词原形),should可以省去,建议记住该句型中的形容词。Itisimportantthatwe(should)learnEnglishwell. Itisnecessarythathe(should)(reported,learned....)that..."据说(据报道,据悉...)"。etoBeijing. (ordered/demand...)that...主句中的过去分词是表示请求,建议,命令等词时,that 后的从句要用虚拟语气(should+动词原形),should可以省;常译为"据建议;有命令...) Itissuggestedthatthemeeting(should)beputoff. Itwasorderedthatwe(should)(ashame...)that...该句型中,that后的从句一般用虚拟语气(should+动词原形),,常译为"竟然"。没有这种意义时,则不用虚拟语气。Itisapitythatsuchathing(should)happeninyourclass.这种事竟然发生在你们班上,真是遗憾! ,真遗憾!(theverytime,thehightime)that...该句型中that后的从句应该用虚拟语气,值得注意的是①常用过去时态表示虚拟.②有时也用should+动词原形,should不能省,常译为"是(正是)...的时侯..." Itistimethatchildrenshouldgotobed. =(second...)timethat...现在完成时Itwasthefirst(second…)timethat…过去完成时It____thefirsttimeI________here.;;;....s
